Background
Rho-associated protein kinase (ROCK) is a key intracellular mediator of cytoskeletal dynamics and cellular motility. Rho kinase mediates many downstream targets of RhoA through phosphorylation, including, for example, myosin light chain, binding subunit and myosin light chain phosphatase of LIM-kinase 2. These substrates mediate actin filament organization and contractile force. In smooth muscle cells, Rho kinase mediates calcium sensitization and smooth muscle contraction. Inhibition of Rho kinase blocks 5-HT and phenylephrine agonist-induced muscle contraction. When introduced into non-smooth muscle cells, Rho kinase induces stress fibrogenesis and is essential for cellular transformation mediated by RhoA. Rho kinase is involved in a number of cellular processes including, but not limited to, cell adhesion, cell motility and migration, growth control, cell contraction and cytokinesis. Rho kinase is also involved in Na/H exchange transport system activation, stress fiber formation, adducin activation and physiological processes such as vasoconstriction, bronchial smooth muscle contraction, vascular smooth muscle and endothelial cell proliferation, platelet aggregation and others.
Inhibition of Rho kinase activity in animal models has demonstrated many benefits of Rho kinase inhibition for the treatment of human diseases. These include cardiovascular diseases such as hypertension, arteriosclerosis, restenosis, cardiac hypertrophy, ocular hypertension, cerebral ischemia, cerebral vasospasm, erectile dysfunction, central nervous system diseases such as neuronal degeneration and spinal cord injury, and models in neoplasias. Inhibition of Rho kinase activity has been shown to inhibit tumor cell growth and metastasis, angiogenesis, arterial thrombotic diseases such as platelet aggregation and leukocyte aggregation, asthma, intraocular pressure regulation, and bone resorption. Rh in patientsoInhibition of kinase activity has the benefits of controlling cerebral vasospasm and ischemic subarachnoid hemorrhage, reducing intraocular pressure, increasing aqueous outflow through relaxation of trabecular meshwork tissue, improving blood flow to the optic nerve, and protecting healthy ganglion cells.
Rho kinase is encoded by two isoforms: ROCK1(ROCK β; p160-ROCK) and ROCK2(ROCK α). ROCK1 and ROCK2 are differentially expressed and mediated in specific tissues. For example, ROCK1 is commonly expressed at relatively high levels, whereas ROCK2 is preferably expressed in the heart and brain and skeletal muscle. The isoforms are also expressed in some tissues and in a developmental stage specific manner. ROCK1 is a substrate for caspase-3 cleavage during apoptosis, whereas ROCK2 is not. Smooth muscle specific basic heregulin is phosphorylated only by ROCK 2.
In view of the range of cellular processes and diseases involved, it would be desirable to have a compound that selectively inhibits one of rho kinases, or inhibits ROCK1 and ROCK 2.

In one aspect, the invention providesRho kinase inhibitors of the formula I. Rho kinase (ROCK), a serine/threonine kinase, acts as a target protein for the small GTP-binding protein Rho and is an important mediator of many cellular functions, including focal adhesion, motility, smooth muscle contraction and cytokinesis. In smooth muscle, ROCK is at Ca2+Plays an important role in the control of sensitization and vascular tone. It regulates the phosphorylation level of myosin II light chain of globulin II, primarily through inhibition by myosin phosphatase, and contributes to agonist-induced Ca in smooth muscle contraction2+And (5) sensitization.
Rho kinase takes two forms: ROCK1 (ROCK. beta.; p160-ROCK) and ROCK2 (ROCK. alpha.) exist. In some embodiments, the compound of formula I selectively inhibits ROCK 1. In some embodiments, the compound of formula I selectively inhibits ROCK 2. In some embodiments, the compound of formula I is non-selective for inhibition by ROCK1 and ROCK 2.
Methods for determining kinase inhibition are well known in the art. For example, the kinase activity of an enzyme and the inhibitory ability of a test compound can be determined by measuring the enzyme-specific phosphorylation of a substrate. Commercial assays and kits can be used. For example, kinase inhibition may be usedDetermined by measurement (Molecular Devices). The assay method involves the use of a fluorescently labeled peptide substrate. Phosphorylation of this tagged peptide by the target kinase helps to bind the peptide to the trivalent metal based nanoparticle via a specific high affinity interaction between the phosphate group and the trivalent metal. The proximity to the nanoparticles results in increased fluorescence polarization. Inhibition of the kinase by a kinase inhibitor prevents phosphorylation of the substrate, thereby limiting binding of the fluorescently labeled substrate to the nanoparticle. Such an assay is compatible with microwell assay formats, enabling the simultaneous determination of the IC of multiple compounds50。
In another aspect of the invention, there is provided a method of treating a patient suffering from a disease, said method comprising administering to a patient in need of such treatment a therapeutically effective amount of a compound of the invention.

The present invention provides pan ROCK inhibitors (i.e., inhibiting ROCK1 and ROCK1 compounds) that are isoform selective, as well as ROCK inhibitors. As noted above, in certain embodiments of the present invention, a ROCK2 selective inhibitor may be preferred. For example, one study found that ROCK2 is often overexpressed in hepatocellular carcinomas while ROCK1 expression is unchanged compared to tumor-free liver. Other cancers that may benefit from treatment with a selective inhibitor of ROCK2 include, but are not limited to, colon and bladder cancers. In contrast, higher ROCK1 expression levels have been observed in breast tumors. Any cancer can be tested to determine if ROCK1 and/or ROCK2 are overexpressed and treated accordingly. In certain instances, ROCK1 and ROCK2 isoforms show similarity in regulating certain downstream targets.

Likewise, these salts can be prepared in situ in the administration vehicle or dosage form preparation process, or by reacting the purified compounds of the invention in their free base form with a suitable base (e.g., hydroxide, carbonate, bicarbonate of a pharmaceutically acceptable metal cation), with aqueous ammonia, or with a pharmaceutically acceptable primary, secondary, or tertiary amine, respectively. Representative alkali or alkaline earth metal salts include lithium, sodium, potassium, calcium, magnesium, and aluminum salts and the like. Representative organic amines useful in the formation of base addition salts include ethylamine, diethylamine, ethylenediamine, ethanolamine, diethanolamine, piperazine and the like. (see, e.g., Berge et al, supra).
Wetting agents, emulsifiers and lubricants such as sodium lauryl sulfate and magnesium stearate, as well as coloring agents, releasing agents, coating agents, sweetening, flavoring and perfuming agents, preservatives and antioxidants can also be present in the composition.
Examples of pharmaceutically acceptable antioxidants include: (1) water-soluble antioxidants such as ascorbic acid, cysteine hydrochloride, sodium bisulfate, sodium metabisulfite, sodium sulfite, and the like; (2) oil-soluble antioxidants such as ascorbyl palmitate, Butylated Hydroxyanisole (BHA), Butylated Hydroxytoluene (BHT), lecithin, propyl gallate, alpha-tocopherol, and the like; and (3) metal chelating agents such as citric acid, ethylenediaminetetraacetic acid (EDTA), sorbitol, tartaric acid, phosphoric acid, and the like.
The formulations of the present invention include those suitable for oral, nasal, topical (including buccal and sublingual), rectal, vaginal and/or parenteral administration. The formulations may conveniently be presented in unit dosage form and may be prepared by any of the methods well known in the art of pharmacy. The amount of active ingredient that can be combined with the carrier materials to produce a single dosage form will vary depending upon the host treated, the particular mode of administration. The amount of active ingredient that can be combined with the carrier materials to produce a single dosage form will generally be that amount of the compound which produces a therapeutic effect. Typically, this amount will range from about 0.1% to about 99%, preferably from about 5% to about 70%, most preferably from about 10% to about 30% of the active ingredient, on a 100% basis.
In certain embodiments, the formulations of the present invention comprise an excipient selected from the group consisting of cyclodextrins, celluloses, liposomes, micelle-forming agents (e.g., bile acids), and polymeric carriers (e.g., polyesters and polyanhydrides); and the compounds of the invention. In certain embodiments, the formulations described above make the compounds of the present invention orally bioavailable.
Methods of preparing these formulations or compositions include the step of bringing into association a compound of the invention with a carrier and, optionally, one or more accessory ingredients. In general, the formulations are prepared by uniformly and intimately bringing into association the compounds of the invention with liquid carriers or finely divided solid carriers or both, and then, if necessary, shaping the product.
Formulations of the invention suitable for oral administration may be in the form of capsules, cachets, pills, tablets, lozenges (using a flavored basis, usually sucrose and acacia or tragacanth), powders, granules, or as a solution or suspension in an aqueous or non-aqueous liquid, or as an oil-in-water or water-in-oil liquid emulsion, or as an elixir or syrup, or as pastilles (using an inert base such as gelatin and glycerin, or sucrose and acacia) and/or as mouthwashes and the like, each containing a predetermined amount of a compound of the invention as the active ingredient. The compounds of the invention may also be administered as a bolus, electuary or paste.
In the solid dosage forms of the invention for oral administration (capsules, tablets, pills, dragees, powders, granules, lozenges, etc.), the active ingredient is mixed with one or more pharmaceutically acceptable carriers, such as sodium citrate or dicalcium phosphate and/or any of the following: (1) fillers or extenders, such as starch, lactose, sucrose, glucose, mannitol, and/or silicic acid; (2) binders, for example, carboxymethylcellulose, alginates, gelatin, polyvinylpyrrolidone, sucrose and/or acacia; (3) humectants, such as glycerol; (4) disintegrating agents, such as agar-agar, calcium carbonate, potato or tapioca starch, alginic acid, certain silicates, and sodium carbonate; (5) solution retarding agents, such as paraffin; (6) absorption enhancers, for example quaternary ammonium compounds and surfactants, such as poloxamers and sodium lauryl sulphate; (7) wetting agents, for example, cetyl alcohol, glyceryl monostearate and nonionic surfactants; (8) adsorbents such as kaolin and bentonite; (9) lubricants, such as talc, calcium stearate, magnesium stearate, solid polyethylene glycols, sodium lauryl sulfate, zinc stearate, sodium stearate, stearic acid and mixtures thereof; (10) a colorant; and (11) a controlled release agent, such as crospovidone or ethylcellulose. In the case of capsules, tablets and pills, the pharmaceutical compositions may also comprise buffering agents. Solid compositions of a similar type may also be employed as fillers in soft and hard shell gelatin capsules using such excipients as lactose or milk sugar as well as high molecular weight polyethylene glycols and the like.
Tablets may optionally be prepared by compression or moulding with one or more accessory ingredients. Compressed tablets may be prepared using binders (for example, gelatin or hydroxypropylmethyl cellulose), lubricants, inert diluents, preservatives, disintegrating agents (for example, sodium starch glycolate or cross-linked sodium carboxymethyl cellulose), surface-active or dispersing agents. Molded tablets may be prepared by molding in a suitable machine a mixture of the powdered compound moistened with an inert liquid diluent.
Tablets and other solid dosage forms of the pharmaceutical compositions of the present invention, such as dragees, capsules, pills and granules, may optionally be scored or prepared with coatings and shells, such as enteric coatings and other coatings well known in the pharmaceutical formulating art. They may also be formulated to provide sustained or controlled release of the active ingredient therein, for example using hydroxypropylmethyl cellulose in varying proportions to provide the desired release profile, other polymeric matrices, liposomes and/or microspheres. They may be formulated for rapid release, e.g. freeze-drying. They may be sterilized, for example, by filtration through a bacterial-retaining filter or by incorporating sterilizing agents in the form of sterile solid compositions that can be dissolved in sterile water, or by incorporating some other sterile injectable medium immediately prior to use. These compositions may also optionally contain opacifying agents and may be such that: they release the active ingredient only or preferably in a certain part of the gastrointestinal tract, optionally in a delayed manner. Examples of embedding compositions that can be used include polymeric substances and waxes. The active ingredient may also be in microencapsulated form, if appropriate with one or more of the above-mentioned excipients.
Liquid dosage forms of the compounds of the invention for oral administration include pharmaceutically acceptable emulsions, microemulsions, solutions, suspensions, syrups and elixirs. In addition to the active ingredient, the liquid dosage forms may contain inert diluents commonly used in the art such as, for example, water or other solvents, solubilizing agents and emulsifiers such as ethyl alcohol, isopropyl alcohol, ethyl carbonate, ethyl acetate, benzyl alcohol, benzyl benzoate, propylene glycol, 1, 3-butylene glycol, oils (in particular, cottonseed, groundnut, corn, germ, olive, castor, and sesame oils), glycerol, tetrahydrofuryl alcohol, polyethylene glycols and fatty acid esters of sorbitan, and mixtures thereof.
In addition to inert diluents, the oral compositions can also include adjuvants such as wetting agents, emulsifying and suspending agents, sweetening, flavoring, coloring, perfuming and preservative agents.
Suspensions, in addition to the active compounds, may contain suspending agents as, for example, ethoxylated isostearyl alcohols, polyoxyethylene sorbitol and sorbitan esters, microcrystalline cellulose, aluminum metahydroxide, bentonite, agar-agar and tragacanth, and mixtures thereof.
Formulations of the pharmaceutical compositions of the present invention suitable for rectal or vaginal administration may be presented as a suppository, which may be prepared by mixing one or more compounds of the present invention with one or more suitable non-irritating excipients or carriers comprising, for example, cocoa butter, polyethylene glycol, a suppository wax or a salicylate, and which is solid at room temperature but liquid at body temperature and will therefore melt in the rectum or vaginal cavity and release the active compound.
Formulations of the invention suitable for vaginal administration also include pessaries, tampons, creams, gels, pastes, foams or spray formulations containing such carriers as are known in the art to be appropriate.
Dosage forms for topical or transdermal administration of the compounds of the present invention include powders, sprays, ointments, pastes, creams, lotions, gels, solutions, patches and inhalants. The active compound may be mixed under sterile conditions with a pharmaceutically acceptable carrier, and with any preservatives, buffers, or propellants which may be required.
In addition to the active compounds of the invention, the ointments, pastes, creams and gels may contain excipients, for example animal and vegetable fats, oils, waxes, alkanes, starches, tragacanth, cellulose derivatives, polyethylene glycols, silicones, bentonites, silicic acid, talc and zinc oxide or mixtures thereof.
Powders and sprays can contain, in addition to a compound of the invention, excipients such as lactose, talc, silicic acid, aluminum hydroxide, calcium silicates and polyamide powder or mixtures of these substances. Sprays can additionally contain conventional propellants, such as chlorofluorohydrocarbons and volatile unsubstituted hydrocarbons, such as butane and propane.
Transdermal patches have the additional advantage of providing controlled delivery of the compounds of the present invention to the body. Such dosage forms may be prepared by dissolving or dispersing the compound in a suitable medium. Absorption enhancers may also be used to increase the flux of compounds through the skin. The rate of such flux can be controlled by providing a rate controlling membrane or dispersing the compound in a polymer matrix or gel.
Ophthalmic formulations, ophthalmic ointments, powders, solutions, and the like are also contemplated as being within the scope of the present invention.
Pharmaceutical compositions of the invention suitable for parenteral administration comprise one or more compounds of the invention in admixture with one or more pharmaceutically acceptable sterile isotonic aqueous or non-aqueous solutions, dispersions, suspensions or emulsions or sterile powders which may be reconstituted into sterile injectable solutions or dispersions prior to use, which may contain sugars, alcohols, antioxidants, buffers, bacteriostats, solutes which render the formulation isotonic with the blood of the intended recipient or suspending or thickening agents.
Examples of suitable aqueous and nonaqueous carriers that may be employed in the pharmaceutical compositions of the present invention include water, ethanol, polyols (such as glycerol, propylene glycol, polyethylene glycol, and the like), and suitable mixtures thereof, vegetable oils (such as olive oil), and injectable organic esters (such as ethyl oleate). Proper fluidity can be maintained, for example, by the use of a coating material, such as lecithin, by the maintenance of the required particle size in the case of dispersions and by the use of surfactants.
These compositions may also contain adjuvants such as preserving, wetting, emulsifying, and dispersing agents. Prevention of the action of microorganisms on the subject compounds can be ensured by the inclusion of various antibacterial and antifungal agents, for example, parabens, chlorobutanol, phenol sorbic acid, and the like. It may also be desirable to include isotonic agents, for example, sugars, sodium chloride, and the like in the compositions. In addition, prolonged absorption of the injectable pharmaceutical form can be brought about by the inclusion of agents which delay absorption, such as aluminum monostearate and gelatin.
In some cases, to prolong the effect of a drug, it is desirable to slow the absorption of the drug from subcutaneous or intramuscular injection. This can be achieved by using a liquid suspension of crystalline or amorphous material which is poorly water soluble. The rate of absorption of the drug then depends on its rate of dissolution, which in turn may depend on crystal size and crystalline form. Alternatively, delayed absorption of a parenterally administered drug form is achieved by dissolving or suspending the drug in an oily vehicle.
Injectable depot forms are made by forming microencapsule matrices of the subject compounds in biodegradable polymers, such as polylactide-polyglycolide. Depending on the ratio of drug to polymer, and the nature of the particular polymer used, the rate of drug release can be controlled. Examples of other biodegradable polymers include poly (orthoesters) and poly (anhydrides). Depot injectable formulations are also prepared by entrapping the drug in liposomes or microemulsions which are compatible with body tissues.
When the compounds of the present invention are administered as medicaments to humans and animals, they can be administered as such or as pharmaceutical compositions containing, for example, 0.1 to 99% (more preferably 10 to 30%) of the active ingredient in combination with a pharmaceutically acceptable carrier.
The formulations of the present invention may be administered orally, parenterally, topically or rectally. They are, of course, administered in a form suitable for each route of administration. For example, they are administered in the form of tablets or capsules by injection, inhalation, ophthalmic lotion, ointment, suppository and the like, for example by injection, infusion or inhalation; by lotion or ointment; and rectally administered by means of suppositories. Oral administration is preferred.
The phrases "parenteral administration" and "parenteral administration" as used herein refer to modes of administration other than enteral and topical administration, typically by injection, and include, but are not limited to, intravenous, intramuscular, intraarterial, intrathecal, intracapsular, intraorbital, intracardiac, intradermal, intraperitoneal, transtracheal, subcutaneous, subcuticular, subcarticulary, subcapsular, subarachnoid, intraspinal and intrasternal injection and infusion.
The phrases "systemic administration", "peripheral administration" and "administered peripheral administration", as used herein, refer to the administration of compounds, drugs or other materials that do not directly enter the central nerve, such that they enter the patient's system and, thus, are metabolized and other similar processes, such as subcutaneous administration.
These compounds may be administered to humans and other animals for treatment by any suitable route of administration, including oral, nasal, such as by, for example, spraying, rectal, intravaginal, parenteral, intracisternal, and topical, such as by powders, ointments, or drops, including buccal and sublingual routes.
Regardless of the route of administration chosen, the compounds of the invention, and/or the pharmaceutical compositions of the invention, may be used in a suitable hydrated form and formulated into pharmaceutically acceptable dosage forms by conventional methods well known to those skilled in the art.
The actual dosage level of the active ingredient in the pharmaceutical compositions of the invention can be varied so as to obtain an amount of active ingredient, composition and mode of administration that is effective to achieve the desired therapeutic response for a particular patient, without being toxic to the patient.
The selected dosage level will depend upon a variety of factors including the activity of the particular compound of the invention or ester, salt or amide thereof employed, the route of administration, the time of administration, the rate of excretion or metabolism of the particular compound employed, the rate and extent of absorption, the duration of treatment, other drugs, compounds and/or materials in combination with the particular compound employed, the age, sex, body weight, condition, general health and past medical history of the patient to be treated, and like factors well known in the medical arts.
A physician or veterinarian of ordinary skill in the art can readily determine and prescribe the effective amount of the pharmaceutical composition required. For example, a physician or veterinarian can start a dose of a compound of the invention used in a pharmaceutical composition below the level required to achieve the desired therapeutic effect and gradually increase the dose until the desired effect is achieved.
In general, a suitable daily dose of a compound of the invention will be that amount of the compound which is the lowest dose effective to produce a therapeutic effect. Such effective dosages will generally depend upon the factors described above. Typically, when used for a given analgesic effect, the oral, intravenous, intracerebroventricular, and subcutaneous doses of a compound of the invention for a patient will range from about 0.0001 to about 100mg per kilogram of body weight per day.
In certain embodiments, a dose of a compound or composition is administered to a subject daily, every other day, every two days, every third day, once a week, twice a week, three times a week, or once every two weeks. If desired, an effective daily dose of the active compound may be administered as two, three, four, five, six or more sub-doses, administered separately at suitable intervals throughout the day, optionally in unit dosage form. In some embodiments, a dose of a compound or composition is administered for 2 days, 3 days, 5 days, 7 days, 14 days, or 21 days. In certain embodiments, a dose of a compound or composition is administered for 1 month, 1.5 months, 2 months, 2.5 months, 3 months, 4 months, 5 months, 6 months, or longer.
The above-described administration regimens are provided for illustrative purposes only and should not be considered limiting. One of ordinary skill in the art will readily appreciate that all dosages are within the scope of the present invention.
Although the compound of the present invention may be administered alone, it is preferable to administer the compound as a pharmaceutical preparation (composition).
The patient receiving such treatment is any animal in need thereof, including primates, particularly humans, as well as other mammals such as horses, cattle, pigs, sheep, and the like; and generally poultry and pets.
The compounds of the invention may be administered as such or in admixture with a pharmaceutically acceptable carrier and may also be administered in combination with antimicrobial agents such as penicillins, cephalosporins, aminoglycosides and glycopeptides. Thus, combination therapy encompasses the sequential, simultaneous and separate administration of the active compounds in such a way that the therapeutic effect of the agent administered first does not completely disappear when a subsequent agent is administered.
The addition of the active compounds of the invention to the animal feed is preferably effected by preparing a suitable feed premix comprising an effective amount of the active compound and introducing said premix into the complete ration (ration).
Alternatively, an intermediate concentrate or feed additive containing the active ingredient may be mixed into the feed. The manner in which such feed premixes and complete rations can be prepared and administered is described in the reference ("Applied Animal Nutrition", w.h. freedman and co., San Francisco, u.s.a., 1969 or "Livestock Feeds and Feeds" O and B books, Corvallis, ore., u.s.a., 1977).
Microemulsion technology can be used to improve the bioavailability of lipophilic (water insoluble) agents. Examples include Trimetrine (Dordunoo, S.K., et al, Drug Development and Industrial Pharmacy, 17(12), 1685-. In addition, microemulsions provide enhanced bioavailability by preferentially directing absorption into the lymphatic system, rather than the circulatory system, which thereby bypasses the liver and prevents destruction of the compound in the hepatobiliary circulation.
In one aspect of the invention, the formulation contains micelles formed by the compounds of the invention and at least one amphiphilic carrier, wherein the micelles have an average diameter of less than about 100 nm. More preferred embodiments provide micelles having an average particle size of less than about 50nm, and even more preferred embodiments provide micelles having an average diameter of less than about 30nm, or even less than about 20 nm.
While all suitable amphiphilic carriers are contemplated, the presently preferred carriers are generally those having a Generally Recognized As Safe (GRAS) status and which can solubilize the compounds of the present invention when the solution is contacted with a complex aqueous phase, such as that present in the human gastrointestinal tract, and which can, in turn, microemulsify the compounds of the present invention in a subsequent stage. Typically, amphiphilic components that meet these requirements have an HLB (hydrophilic to lipophilic balance) value of 2-20 and a structure that includes a linear aliphatic group in the range of C-6 to C-20. Examples are polyglycolized fatty acid glycerides and polyethylene glycols.
Particularly preferred amphiphilic carriers are saturated and monounsaturated pegylated fatty acid glycerides, such as those obtained from different vegetable oils, which are fully or partially hydrogenated. Such oils may advantageously be composed of fatty acid triglycerides, fatty acid diglycerides and fatty acid monoglycerides and corresponding fatty acid diglycerides and monoglycerides, wherein a particularly preferred fatty acid composition comprises capric acid 4-10%, capric acid 3-9%, lauric acid 40-50%, myristic acid 14-24%, palmitic acid 4-14% and stearic acid 5-15%. Another useful type of amphiphilic vehicle includes: sorbitan and/or sorbitol partially esterified with saturated or monounsaturated fatty acids (SPAN-series) or corresponding ethoxylated analogues (TWEEN-series).
Commercially available amphiphilic carriers are specifically contemplated, including the Gelucire-series, Labrafil, Labrasol, or Lauroglicol (all manufactured and distributed by Gattefose Corporation, Saint Priest, France), PEG-mono-oleate, PEG-dioleate, PEG-mono-laurate and dilaurate, lecithin, polysorbate 80, and the like (produced and distributed by several companies in the United states and around the world).
Hydrophilic polymers suitable for use in the present invention are those that are readily soluble in water, capable of being covalently linked to vesicle-forming lipids, are tolerated in vivo and have no toxic effects (i.e., are biocompatible). Suitable polymers include polyethylene glycol (PEG), polylactic acid (also known as polylactide), polyglycolic acid (also known as polyglycolide), polylactic-polyglycolic acid copolymers, and polyvinyl alcohol. Preferred polymers are those having a molecular weight of from about 100 or 120 daltons to about 5,000 or 10,000 daltons, and more preferably from about 300 daltons to about 5,000 daltons. In a particularly preferred embodiment, the polymer is polyethylene glycol having a molecular weight of about 100 to about 5,000 daltons, more preferably having a molecular weight of about 300 to about 5,000 daltons. In a particularly preferred embodiment, the polymer is polyethylene glycol of 750 daltons (PEG (750)). The polymers used in the present invention have significantly smaller molecular weights (about 100 daltons) compared to the large molecular weights of 5000 daltons or higher used in standard pegylation techniques. The polymer may also be defined by the number of monomers therein; one preferred embodiment of the present invention uses a polymer having at least about 3 monomers, such a PEG polymer comprising three monomers (about 150 daltons).
Other hydrophilic polymers suitable for use in the present invention include polyvinylpyrrolidone, polymethyloxazoline, polyethyloxazoline, polyhydroxypropylmethacrylamide, polymethacrylamide, polydimethylacrylamide and derivatized celluloses, such as hydroxymethylcellulose or hydroxyethylcellulose.
In certain embodiments, the formulations of the present invention comprise a biocompatible polymer selected from the group consisting of: polyamides, polycarbonates, polyolefins, polymers of acrylates and methacrylates, polyvinyl polymers, polyglycolides, polysiloxanes, polyurethanes and copolymers thereof, cellulose, polypropylene, polyethylene, polystyrene, polymers of lactic acid and glycolic acid, polyanhydrides, poly (ortho) esters, poly (butyric acid), poly (valeric acid), poly (lactide-co-caprolactone), polysaccharides, proteins, polyhyaluronic acid, polycyanoacrylates and blends, mixtures or copolymers thereof.
The release profile of the formulations of the present invention depends on the encapsulating material, the concentration of the encapsulated drug and the presence of the release modifier. For example, the release may be manipulated to be pH dependent, e.g.A pH sensitive coating is used that releases only at low pH (e.g. in the stomach) or higher pH (e.g. in the intestine). Enteric coatings may be used to prevent release from occurring until after passage through the stomach. Various coatings or mixtures of nitrilamines encapsulated in different materials may be used to obtain an initial release in the stomach followed by a later release in the intestinal tract. Release can also be manipulated by the addition of salts or pore formers which can increase water uptake or drug release by diffusion from the capsule. Excipients that alter the solubility of the drug may also be used to control the release rate. Agents that enhance degradation or release from the matrix may also be incorporated. They may be added to the drug, added as a separate phase (i.e., as microparticles), or may be co-dissolved in the polymer phase, depending on the compound. In all cases, the amount should be between 0.1 and 30% (w/w polymer). Types of degradation enhancers include inorganic salts such as ammonium sulfate and ammonium chloride, organic acids such as citric acid, benzoic acid, and ascorbic acid, inorganic bases such as sodium carbonate, potassium carbonate, calcium carbonate, zinc carbonate, and zinc hydroxide, and organic bases such as protamine sulfate, spermine, choline, ethanolamine, diethanolamine, and triethanolamine, and surfactants such as Andthe pore former is added as a microparticle, which adds the microstructure to the matrix (i.e., water soluble compounds such as inorganic salts and sugars). The range should be 1 to 30% (w/w polymer).
Ingestion can also be manipulated by varying the residence time of the particles in the intestinal tract. This can be achieved, for example, by coating the particles with a mucoadhesive polymer, or by selecting a mucoadhesive polymer as the encapsulating material. Examples include most polymers with free carboxyl groups, such as chitosan, cellulose, and in particular polyacrylates (polyacrylate, as used herein, refers to polymers containing acrylate groups such as cyanoacrylates and methacrylates and modified acrylate groups).
The above-described administration regimens are provided for illustrative purposes only and should not be considered limiting. One of ordinary skill in the art will readily appreciate that all dosages are within the scope of the present invention.
Advantageously, the compounds of the present invention may be administered to a patient in need thereof together with a second agent. When the rho kinase inhibitor is administered with a second agent, the rho kinase inhibitor and the second agent may be administered sequentially or concomitantly. By sequentially is meant that one agent is administered for a period of time, then a second agent is administered, after which the first agent may be administered. When the agents are administered sequentially, the level or one agent may not be maintained at a therapeutically effective level when the second agent is administered, and vice versa. Concomitantly means that the first and second agents are administered according to a regimen that maintains both agents at substantially therapeutically effective levels, even if the agents are not administered simultaneously. Each agent can be administered in a single or multiple doses, and the doses can be administered on any regimen, including but not limited to twice daily, once weekly, once biweekly, and once monthly.
The invention also includes adjunctive administration. By adjunctive administration is meant administration of a second agent to the patient in addition to the first agent that has been administered to treat the disease or disease symptoms. In some embodiments, adjunctive administration includes administration of a second agent to the patient, wherein administration of the first agent is not sufficient to treat the disease or disease symptoms. In other embodiments, adjunctive administration includes administration of the second agent to a patient whose disease has been effectively treated by administration of the first agent, where combination therapy is expected to improve the outcome of the treatment. In some embodiments, the effect of administering the first and second agents is synergistic. In some embodiments, administration of the first and second agents prevents relapse or extends the time before relapse compared to administration of any of the agents alone. In some embodiments, administration of the first and second agents allows for a reduction in the dose and/or frequency of administration of the first and second agents.
In one embodiment of the invention, the rho kinase inhibitors and antineoplastic agents of the invention are administered to a subject in need thereof. In another embodiment, the rho kinase inhibitor and angiogenesis inhibitor of the invention are administered to a subject in need thereof. In another embodiment, the rho kinase inhibitor and the anti-inflammatory agent of the invention are administered to a subject in need thereof. In another embodiment, the rho kinase inhibitor and the immunosuppressant of the invention are administered. The second agent can be, but is not limited to, a small molecule, an antibody or antigen-binding fragment thereof, or radiation.
Anti-neoplastic agents include, but are not limited to, cytotoxic chemotherapeutic agents, targeted small molecules and biomolecules, and radiation. In addition to the rho kinase inhibitors of the invention, compounds and agents for tumor therapy that may be administered include the following: irinotecan, etoposide, camptothecin, 5-fluorouracil, hydroxyurea, tamoxifen, paclitaxel, capecitabine, carboplatin, cisplatin, bleomycin, actinomycin D, gemcitabine, doxorubicin, nordstycin, cyclophosphamide, and radiation therapy, which may be in vitro (e.g., External Beam Radiation Therapy (EBRT)) or in vivo (e.g., Brachytherapy (BT)).
Targeting small molecules and biomolecules include, but are not limited to, inhibitors of components of signal transduction pathways, such as modulators of tyrosine kinases and inhibitors of receptor tyrosine kinases and agents that bind to antigens specific to tumors. Examples include inhibitors of Epidermal Growth Factor Receptor (EGFR), including gefitinib, erlotinib, cetuximab, inhibitors of HER2 (e.g., trastuzumab emtansine (trastuzumab-DM 1; T-DM1), and pertuzumab), anti-VEGF antibodies and fragments (e.g., bevacizumab), antibodies that inhibit CD20 (e.g., rituximab, ibritumomab (rititumomab)), anti-VEGFR antibodies (e.g., ramucirumab (IMC-1121B), IMC-1C11, and CDP791), anti-PDGFR antibodies, and imatinib. The small molecule kinase inhibitor may be specific for a particular tyrosine kinase or may be an inhibitor of two or more kinases. For example, the compound N- (3, 4-dichloro-2-fluorophenyl) -7- ({ [ (3aR, 6aS) -2-methyloctahydrocyclopenta [ c ] pyrrol-5-yl ] methyl } oxy) -6- (methoxy) quinazolin-4-amine (also known aS XL647, EXEL-7647, and KD-019) is an in vitro inhibitor of several Receptor Tyrosine Kinases (RTKs), including EGFR, EphB4, kdr (VEGFR), Flt4(VEGFR3), and ErbB2, and is also an inhibitor of SRC kinases that are involved in the pathway leading to tumor unresponsiveness to certain TKIs. In one embodiment of the invention, treating a subject in need thereof comprises administration of a rho kinase inhibitor of formula I and administration of KD-019.
Dasatinib (BMS-354825; Bristol-Myers Squibb, New York) is another ATP-site competitive Src inhibitor that is orally bioavailable. Dasatinib also targets Bcr-Abl (US FDA approved for patients with Chronic Myelogenous Leukemia (CML) or Philadelphia chromosome positive (Ph +) Acute Lymphoblastic Leukemia (ALL)) as well as c-Kit, PDGFR, c-FMS, EphA2 and Src family kinases. Two other oral tyrosine kinase inhibitors of Src and Bcr-Abl are bosutinib (SKI-606) and Seatinib (AZD 0530).
According to the present invention, an angiogenesis inhibitor may be administered to a subject in combination with a compound of the present invention. Angiogenesis inhibitors include any substance that inhibits the growth of new blood vessels. For example, angiogenesis inhibitors include VEGF, antagonists of PlGF, and VEGF receptors, including the antibodies disclosed herein. An inhibitor refers to an inhibitor of a biological process or an inhibitor of a target. In this regard, an angiogenesis inhibitor is an agent that reduces angiogenesis. Rho kinase inhibitors are agents such as competitive inhibitors of ATP binding that inhibit the intrinsic activity of Rho kinase or block Rho kinase interactions. An antagonist refers to a substance that reduces or inhibits activity or function in a cell associated with a target. For example, a VEGF antagonist reduces or blocks function in a cell associated with VEGF. VEGF antagonists may act on VEGF by binding to VEGF and blocking binding to its receptor and/or may act on another cellular component involved in VEGF-mediated signal transduction. Similarly, a VEGFR2 antagonist is an agent that reduces or blocks VEGF 2-mediated signal transduction by binding to VEGFR2 and blocking ligand binding or interaction with a VEGFR2 substrate, or acts on another cellular component to reduce or block VEGFR 2-mediated signal transduction. Thus, angiogenesis inhibitors include the novel anti-VEGFR 2 antibodies shown herein (figure 11) and, but are not limited to, antagonists and complements of VEGF, VEGFR1, VEGFR2, PDGF, PDGFR- β, neuropilin-1 (NRP 1).
Non-limiting examples of VEGF binding agents include VEGF antibodies and VEGF traps (i.e., the ligand binding domain of the VEGF receptor). In general, a VEGF trap is a protein that contains the VEGF binding domain of one or more VEGF receptor proteins. VEGF-traps include, but are not limited to, soluble VEGFR-1, soluble neuropilin 1(NRP1), soluble VEGFR-3 (which binds VEGF-C and VEGF-D), and aflibercept (Zaltrap; Eyelea; VEGF trap R1R2), fragments of the extracellular domains of the human vascular endothelial growth factor receptors VEGFR1 and VEGFR2, including a constant domain (Fc) fused to human IgG 1. Corbeset (KH902) is a fusion protein comprising extracellular domain 2 of VEGFR-1(Flt-1) and extracellular domains 3, 4 of VEGFR-2(KDR) fused to the Fc portion of human IgG 1. Several VEGF traps containing various combinations of KDR and FLT-1 Ig-like domains are described in U.S. patent 8,216,575. DARPin (an acronym for designed ankyrin repeat protein) is a genetically engineered antibody mimetic protein that usually exhibits high specificity and high affinity for target protein binding.Is a Vascular Endothelial Growth Factor (VEGF) inhibitor and has been in clinical trials for the treatment of wet macular degeneration and diabetic macular edema.
According to the invention, VEGF expression can be targeted. For example, VEGF inhibitor PTC299 targets VEGF posttranscriptionally by selectively binding to the 5 '-and 3' -untranslated regions (UTRs) of VEGF messenger rna (mrna), thereby preventing translation of VEGF. Pegaptanib (Macugen) is an RNA aptamer to VEGF-165.
Placental growth factor (PlGF) has been implicated in pathological angiogenesis. PlGF is structurally related to VEGF and is also a ligand for VEGFR-1. Thus, VEGF traps comprising the extracellular domain of VEGFR1 (see above) may be used to target PlGF.
PDGF is composed of four polypeptide chains forming homodimers PDGF-AA, BB, CC and DD, and heterodimer PDGF-AB. The PDGF receptors (PDGFR) - α and- β mediate PDGF function. Specifically, PDGFR α binds to PDGF-AA, -BB, -AB, and-CC, while PDGFR β interacts with-BB and-DD. Non-limiting examples of PDGF binding agents include anti-PDGF antibodies and PDGF traps. Agents targeting PDGF include FovistaTM(E10030, Ophthotech), Pegylated aptamers target PDGF-B and AX102(Sennino et al, 2007, Cancer Res.75 (15): 7359-67), DNA oligonucleotide aptamers that bind PDGF-B.
Agents targeting the PDGF receptor include ramucirumab (IMC-3G3, human IgG) 1) (an anti-PDGFR-alpha antibody), Clalanib (CP-868596) (a PDGFR-alpha (IC)500.9nM) and PDGFR β (IC)501.8nM) and nilotinib)(an inhibitor of PDGFR alpha and PDGFR beta and other tyrosine kinases).
Angiogenesis inhibitors include intracellular agents that block signal transduction mediated by, for example, ligands for VEGF, PDGF, VEGF or PDGF receptors or complement. The intracellular agent inhibiting angiogenesis inhibitor includes, but is not limited to, the following. Sunitinib (Sutent; SU11248) is a pan-specific small molecule inhibitor of VEGFR1-VEGFR3, PDGFR α and PDGFR β, stem cell factor receptor (cKIT), Flt-3 and colony stimulating factor-1 receptor (CSF-1R). Atertinib (AG 013736; Inlyta) is another small molecule tyrosine kinase inhibitor that inhibits VEGFR-1-VEGFR-3, PDGFR and cKIT. Cediranib (AZD2171) is an inhibitor of VEGFR-1-VEGFR-3, PDGFR β and cKIT. Sorafenib (Nexavar) is another small molecule inhibitor of several tyrosine protein kinases including VEGFR, PDGFR and Raf kinases. Pazopanib (Votrient; (GW786034) inhibits VEGFR-1, -2, and-3, cKIT, and PDGFR. Foretinib (GSK 1363089; XL880) inhibits VEGFR2 and MET. CP-547632 as potent inhibitors of VEGFR-2 and basic Fibroblast Growth Factor (FGF) kinases E-3810((6- (7- ((1-aminocyclopropyl) methoxy) -6-methoxyquinolin-4-yloxy) -N-methyl-1-naphthamide) inhibits VEGFR-1, -2, and-3 and FGFR-1 and-2 kinases in the nanomole range Blocket (BMS-582664) is a VEGFR-2 inhibitor that also inhibits FGF receptor signaling CT-322(Adnectin) is a small protein based on the human fibronectin domain that binds to and inhibits activation of VEGFR 647 2 VEGFR (Cavalpre; Zactica; ZD 2) is VEGFR 647647-1, Inhibitors of EGFR and RET tyrosine kinase. X-82 (Xcoverage) is a small molecule indolone inhibitor that signals through the growth factor receptors VEGFR and PDGFR.
Anti-inflammatory and immunosuppressive agents include steroid drugs such as glucocorticoids (e.g., dexamethasone), FK506 (tacrolimus), cyclosporine, fingolimod, interferons such as IFN β or IFN γ, tumor necrosis factor- α (TNF- α) binding proteins such as infliximab (Remicade), etanercept (Enbrel) or adalimumab (Humira), and mycophenolic acid.
In certain embodiments, the ROCK inhibitor of the present invention is co-administered with an agent for treating a metabolic disorder. For example, for the treatment of obesity, the ROCK inhibitor may be combined with a weight loss drug, such as, but not limited to, phentermine, a fat adsorption inhibitor (e.g., cenicr), an appetite suppressant, and the like. Methods for aiding weight loss include, for example, gastric banding, gastric bypass, or gastric restriction. For insulin resistance or metabolic syndrome or hyperinsulinemia, the ROCK inhibitors of the invention may be co-administered with cholesterol level lowering compounds, e.g., one or more drugs such as statins, fibrates or nicotinic acid. For hypertension associated with this disease, the ROCK inhibitors of the invention may be co-administered with, for example, one or more antihypertensive drugs such as diuretics or Angiotensin Converting Enzyme (ACE) inhibitors. The ROCK inhibitors of the present invention may be used in therapeutic regimens that include lifestyle changes, such as increased physical activity, improved diet, and/or smoking cessation. In certain embodiments, the ROCK inhibitor is ROCK2 selective.
Th17 cells are secreted by IL-17, IL-21 and IL-22Auxiliary CD4+A new subset of T cells. The pro-inflammatory activity of Th17 cells may be beneficial to the host during infection, but uncontrolled Th17 function has been associated with and positively implicated in the development of several autoimmune pathologies and acute Graft Versus Host Disease (GVHD), a disease characterized by selective epithelial damage to target organs mediated by mature T cells present in stem cell or bone marrow vaccination. Indeed, high levels of IL-17 associated with destruction of synovial tissue and disease activity were detected in sera and biopsies of patients with Rheumatoid Arthritis (RA) and Systemic Lupus Erythematosus (SLE). The pathological effects of IL-17 in arthritic joints are associated with stimulation and production of its pro-inflammatory cytokines, and increased recruitment of T cells and innate immune cells. Furthermore, the number of Th17 cells was significantly increased in peripheral blood of RA patients after ex vivo stimulation with anti-CD 3/CD28 antibody, and elevated concentrations of IL-17 could be seen in the supernatant of their PBMCs. In addition, myelin-reactive Th17 cells were enriched and produced high amounts of IL-22 and IFN- γ in Multiple Sclerosis (MS) patients. Furthermore, a significantly higher amount of IL-17 compared to healthy areas of the same subject with Crohn's Disease (CD) +Cells are detected in the region of the intestine affected by the disease.
The development and function of Th17 cells depends on the activation of specific intracellular signaling pathways. The steroid receptor type nuclear receptor ROR γ t is selectively expressed in Th17 cells and appears to be desirable for IL-17 production. It has been observed that induction of ROR γ t is mediated by IL-6, IL-21 and IL-23 via STAT 3-dependent mechanisms. STAT3 also binds directly to the IL-17 and IL-21 promoters. In addition to ROR γ t and STAT3, interferon regulatory factor 4(IRF4) is required for the differentiation of Th17 cells because IRF4 KO mice are unable to mount a Th17 response and are resistant to the development of an autoimmune response. Recent studies have shown that phosphorylation of IRF4 by Rho kinase 2(ROCK2) modulates the development of IL-17 and IL-21 production and autoimmunity in mice.
According to the present invention, targeting Th17 (IL-17-secreting) cells via rho kinase inhibition provides a method for treating Th17 cell-mediated diseases in humans, including but not limited to autoimmune diseases such as Rheumatoid Arthritis (RA), Multiple Sclerosis (MS), Systemic Lupus Erythematosus (SLE), psoriasis, crohn's disease, atopic dermatitis, eczema, and GVHD. In one embodiment of the invention, the Rho kinase inhibitor is a compound of formula I. In some embodiments, the rho kinase inhibitor inhibits ROCK1 and ROCK 2. In some embodiments, the rho kinase inhibitor selectively inhibits ROCK 2. Selective inhibition of ROCK2 provides treatment for Th17 cell-mediated diseases and reduces or prevents toxicity associated with complete inhibition of ROCK activity.
Regulatory T cells (tregs) play a key role in the maintenance of immune tolerance to self-antigens and suppression of autoimmune responses, but at the same time prevent an effective immune response to tumor cells. Indeed, tregs isolated from peripheral blood of patients with autoimmune diseases, such as Rheumatoid Arthritis (RA) and Multiple Sclerosis (MS), show a defect in their ability to suppress effector T cell function, while an increased accumulation of tregs is associated with a poor prognosis in many cancers. Thus, the level of Treg function affects the balance between effective immunity and avoidance of pathological autoreactivity.
The development and function of tregs depends on the activation of specific signal transduction pathways. Both TGF- β and IL-2 activation expression of Foxp3 and STAT5 transcription factors play an important role in the control of Treg suppressive function. On the other hand, upregulation of pro-inflammatory cytokines by STAT3 phosphorylation inhibited Foxp3 expression. According to the present invention, pharmacological inhibition of ROCK2 (e.g., inhibition mediated by siRNA specific for ROCK2 with selective ROCK2 inhibitors such as KD025, ROCK 2), but not ROCK1, results in the down-regulation of STAT3 phosphorylation, interferon regulatory factor 4(IRF4) and steroid receptor type nuclear receptor ROR γ T protein levels in human T cells. Thus, the ROCK2 signaling pathway may be involved in the regulation of Treg function.

ROCK1 and ROCK2 Compound Selectivity
Rho kinase inhibition dose response curves were obtained from Millipore immune-based 96-well plate assay (Millipore catalog No. CSA 001). Purified active ROCK1 and ROCK2 were obtained from Invitrogen (ROCKI catalog No., PV3691 and ROCK2 catalog No., PV 3759). The kit components include assay plates that are pre-coated with recombinant MYPT1, which contains specifically phosphorylated Thr 696. The inhibitory activity of the compounds was measured according to the manufacturer's protocol. Briefly, a reduced concentration of test compound or a known ROCK inhibitor, Y-27963 (from 50 to 0.003uM) was added to a reaction buffer containing 5mM MgCl2 and 10 milliunits ROCK1 or ROCK2 in assay dilution buffer. This mixture was overlaid on a 96-well plate and the reaction was started by adding 2.5uM ATP. The assay was performed at 30 ℃ for 30 minutes and gently shaken at 120 rpm. The assay was terminated by washing the plate 3 times with Tris-buffered saline and tween wash buffer. Anti-phosphorylated MYPT1(Thr696) antibody was added to each well to detect phosphorylated substrate and incubated at room temperature for 1 hour, after which HR-labeled anti-rabbit IgG secondary antibody was added over 1 hour at room temperature. After washing the assay was developed using substrate reagents and the absorbance at 450nm was read on a Tecan Infinite M1000, reflecting the relative residual ROCK phosphorylation activity.
Data representing the inhibition of ROCK1 and ROCK2, as well as the selectivity of certain compounds for ROCK2 inhibition, are shown in table 1.
The dose response curve for inhibition of ROCK1 to inhibition of ROCK2 is shown in figure 5.
Example 182
ROCK1 and ROCK2 Compound Selectivity
The dose response curve for Rho kinase inhibition was derived fromInvitrogen Z′-LYTETMKinase assay kit (Invitrogen catalog No. PV 3793). Purified active ROCK1 and ROCK2 were obtained from Invitrogen (ROCK1 catalog No., PV3691 and ROCK2 catalog No., PV 3759). The kit components include coumarin and fluorescein labeled myosin light chain 2(KKRPQRRYSNVF) -based peptides, proprietary proteases containing visualization reagents, and proprietary termination buffers for terminating visualization reactions. The inhibitory activity of the compounds was measured according to the manufacturer's protocol. Briefly, reduced concentrations of test compound or known ROCK inhibitor Y-27963 (from 10uM to 2.56X 10)-5uM) was added to a solution containing 50mM HEPES pH 7.5, 5mM MgCl25mM EGTA and 0.05% Brij-35, and ROCK1 at 0.18ug/mL or ROCK2 at 0.8ug/mL in assay dilution buffer. The mixture was overlaid in a white 96-well half-zone plate and the reaction was started by adding 5uM ATP ROCK1 or 12uM ATP ROCK 2. The assay was performed at room temperature for 1 hour, followed by addition of the developing reagent and further incubation at room temperature for 1 hour. A stop reagent was then added and the reaction and coumarin and fluorescein emission signals were immediately read on a Tecan Infinite M1000 fluorescence plate reader (excitation: 400 nm; emission 445nm and 520nm respectively). Percent phosphorylation values were calculated by comparing the emissivity of the test sample to a control sample, and the concentration of inhibitor producing inhibition of kinase activity 1/2 (IC) was determined using Prism 50). Table 2 provides the IC for the compounds of the above examples50And (4) concentration. Several compounds also showed activity in a preliminary assay measuring inhibition of myosin light chain phosphorylation (pMLC). For compounds labeled ND, activity was not detectable under the test conditions employed.

ROCK2 selectionSelective inhibitor KD025 inhibits IL-17/IL-21 in human CD4 in vitro+Secretion and proliferation in T cells
The activation of resting T cells, which leads to cytokine secretion and proliferation, involves two distinct signals from Antigen Presenting Cells (APCs) that are mimicked by the co-stimulation of the T Cell Receptor (TCR)/CD3 complex with the CD28 receptor. By using freshly purified CD4+Human T cells and stimulatory antibodies against CD3 and CD28 to stimulate IL-17 and IL-21 secretion in response to TCR activation, treatment with the ROCK2 selective inhibitor KD025 was found to significantly inhibit IL-17 and IL-21 secretion in a dose dependent manner. Under the same conditions, the inhibition of IFN- γ secretion was less robust and was only significant at high doses (10 μ M) of the inhibitor (fig. 7A). Similarly, any inhibition of IL-2 secretion was observed only at the highest concentration of KD025 (10. mu.M). Consistent with the inhibitory effect on cytokine secretion, treatment of T cells with KD025 down-regulated their ability to proliferate in response to TCR stimulation in vitro (fig. 7B).
Example 184
ROCK2 siRNA (but not ROCK1 siRNA) inhibited IL-17 and IL-21 secretion
To demonstrate the role of ROCK2 in regulating IL-17 and IL-21 secretion in human T cells, we specifically silenced ROCK1 and ROCK2 expression by RNA interference. The specificity ROCK1 and ROCK2 small interfering rnas (sirnas) reduced protein expression levels by 72% and 84%, respectively. Silencing of ROCK2 (but not ROCK1) significantly reduced IL-17 and IL-21 with minimal effect on IFN- γ secretion in human T cells (figure 8).
Example 185
KD025 inhibits STAT3 phosphorylation
STAT3 plays a key role in Th17 differentiation via regulation of ROR γ t expression and direct binding to the IL-17 and IL-21 promoters. Furthermore, recent studies have shown that RhoA-dependent STAT3 stimulation requires ROCK activity and leads to activation of STAT3 phosphorylation at amino acid Y705. Using two different experimental designs, KD025 was shown to significantly down-regulate phosphorylation of STAT 3. In one experiment, T cells were pretreated with KD025 and then stimulated with anti-CD 3/CD28 antibodies. Pretreatment with KD025 resulted in a decrease in phosphorylation of STAT3 (fig. 9A). In different experiments, we cultured cells for 5 days under Th 17-lag conditions, then treated with the ROCK2 selective inhibitor for 3 hours. STAT3 phosphorylation was reduced by treatment with ROCK2 inhibitor (fig. 9B). In a separate experiment, a decrease in phosphorylation of STAT3 as well as IFR4 and ROR γ T was verified (fig. 9C).
Example 186
KD025 down-regulated CD4 in patients from RA+IL-17, IL-21 and IFN-gamma secretion in T cells and reduced increased frequency of IFN-gamma and IL-17 expressing cells
Rheumatoid Arthritis (RA) is a chronic autoimmune inflammatory disease that results in destruction of joint structures. Although the pathogenic events involved in the development of RA are not well understood, the critical role of pro-inflammatory cytokines such as TNF- α, IL-1 β, IFN- β, IL-6 and newer IL-17 in the induction and maintenance of the pathogenesis of RA is well documented. Furthermore, the frequency of Th17 cells in peripheral blood of RA patients was significantly increased and correlated with the Disease Activity Score (DAS) compared to healthy controls.
CD4+T cells were purified from peripheral blood of RA patients at different stages of the disease or from healthy controls and stimulated ex vivo with anti-CD 3/CD28 antibodies in the presence of KD 025. In CD4+In T cells, the ROCK2 selective inhibitor significantly down-regulated IL-17, IL-21, and IFN- γ secretion in response to TCR stimulation in a STAT 3-dependent pattern (FIG. 10A). The extent of inhibition of IFN- γ secretion was comparable to the level of inhibition of IL-17 and IL-21 compared to healthy controls. In RA patients, inhibition of IFN- γ production correlated with Disease Activity Score (DAS) (fig. 10B). CD4 from 2 different RA patients +Culturing of T cells in the presence of KD025 significantly reduced the frequency of both IL-17 producing cells and IFN- γ producing cells, as indicated by intracellular staining (fig. 10C).
Example 187
KD025 upregulates STAT-5 phosphorylation
CD4+The presence of T-cell cytokines IL-6, TGF-beta, IL-1 beta, IL-23 and antigen stimulation results in the secretion of IL-17 and IL-21Induction and development of effector subsets of Th17 cells. At the same time, the development and function of tregs is inhibited. To determine the effect of ROCK2 inhibition on Treg, freshly purified human CD4 was treated with stimulatory antibodies to CD3/CD28 (5 μ g/ml), TGF- β (5ng/ml) and IL-1 β (50ng/ml) in the presence of the selective ROCK2 inhibitor KD025 at concentrations of 0 μ M, 0.5 μ M, 1 μ M and 2.5 μ M+T cells were activated for 2 days. Western blot analysis showed that treatment with KD025 significantly upregulated phosphorylation of STAT5 at site Y694 in a dose-dependent manner. (FIG. 11). Thus, ROCK2 inhibits the down-regulation of STAT3 phosphorylation, whereas human CD4, activated under Th 17-lag conditions+STAT5 phosphorylation is increased in T cells.
Example 188
KD025 increased Foxp3+The cells are in CD4+Proportion in T cells
Foxp3 is a lineage specific transcription factor for tregs and is critical for the development and suppressive function of these cells. STAT5 signaling positively regulates the in vitro and in vivo induction and stabilization of Foxp3 expression in T cells. Human CD4 with a selective ROCK2 inhibitor KD025 +Treatment of T cells significantly increased Foxp3 following 5 days of in vitro Th17 time lag activation+Percentage of cells. (FIG. 12).
Example 189
KD025 up-regulated in CD4+CD25-Treg inhibition of IL-17 secretion in T cells
Freshly purified CD4 with KD025+CD25+Human Treg cells were treated for 3 hours, washed, and CD4+CD 25-effector T cells were mixed at 1: 4 and 1: 9 (Treg: T effector) and activated for 2 days using stimulatory antibodies against CD3 and CD 28. KD 025-mediated inhibition of ROCK2 significantly increased Treg inhibition at CD4+CD25-The ability of IL-17 secretion in effector T cells. (FIG. 13).
Example 190
KD025 inhibited TGF-beta induced STAT3 and MLC phosphorylation in a manner independent of SMAD2/3
The selective ROCK2 inhibitor KD025 down-regulated TGF- β induced STAT3 and MLC phosphorylation in a dose-dependent manner, but phosphorylation of SMAD2/3 remained unchanged. (FIG. 14). TGF- β is involved in the development and function of both Th17 and Treg subsets of T cells. However, TGF- β regulates Th17 cells in a Smad2/3 independent manner that is thought to be atypical TGF- β induced signaling when tregs are regulated in a Smad2/3 dependent signaling mechanism. Furthermore, ROCK proteins have been shown to be involved in Smad-independent TGF- β signaling in cancer cells.
Example 191
Treatment of patients with KD025 inhibited ex vivo stimulation of IL-17 and IL-21 production in isolated PBMCs
8 patients were administered 120 mg/day KD025 or placebo on days 1 and 8-14 of the experimental period. Peripheral Blood Mononuclear Cells (PBMC) were collected at the beginning and end of the assay and stimulated by plating on immobilized anti-CD 3/CD28 antibody for 72 hours, and levels of IL-17, IL-21, and IFN- γ were determined. FIG. 15 shows that high levels of IL-17 and IL-21 can be induced in PBMCs isolated from six subjects on day 1. Of these six subjects, five received the ROCK2 selective inhibitor KD025 and one received placebo. Induction of IL-17 secretion was significantly inhibited in PBMCs isolated from four of five subjects treated with KD025 (fig. 15B), and induction of IL-21 secretion was significantly inhibited in PBMCs from all five subjects treated with KD025 (fig. 15A). No effect on IFN-. gamma.was observed.
Cytokine-induced inhibition was then determined in 22 patients administered KD025 at 40 mg/day, 120 mg/day, 240 mg/day, or 320 mg/day. FIGS. 15D-F show the dose-response relationship for IL-21, IL-17, and IFN- γ secretion, respectively.

Table 4 shows the amino acid sequences of the CDRs and the variable domains of the light chain. K for Mabs 105, 106 and 107dIncrease by about 10 fold each (0.24 nM, 0.22nM and 0.12nM, respectively).
