Background technique

In recent years, the targeted drug delivery system mediated based on drug receptor has been widely studied, targeted drug transmitting system Its specific target tropism can be improved in system, overcomes the problems, such as that drug distribution is wide, toxic side effect is serious.Wherein, agglutinin receptor is One kind is distributed in the glycoprotein, glycolipid or saccharide complex of cell membrane surface, can specific recognition and bound fraction glycosyl.Mannose Receptor is most important efficient endocytosis agglutinin receptor, and function includes removing endogenous molecule, promoting antigen presentation, adjust carefully Born of the same parents' activation and transport, also with the immunologic escape of tumour and shift closely related, be mainly expressed in macrophage, dendritic cells with Tumour cell, can specific recognition mannose glycosyl molecule.Mannose group as most potential targeting group, have it is nontoxic, It many advantages, such as non-immunogenicity, good biocompatibility and biodegradability, can be widely used for drug delivery system It is glycosylation modified.

As most classic nano target drug administration carrier, the exposure basis of targeting is based on difference for liposome, nanoparticle Organ is selective to diameter of particle size intake situation difference to be gathered in the lymphoid tissues organ such as lung, to improve anti-swollen The therapeutic effect in each organ of tumor medicine.It, which is prepared, simply has controlled release, non-immunogenicity, and the features such as raising curative effect. But after targeting is realized in the endocytosis of liposome, nanoparticle dependence macrophage, stabilization during targeting dilivery Property and lesion part intake efficiency it is also relatively low, targeting also needs further continuous improve.Thus with life The continuous development of object pharmacy, material science, nanotechnology improves nanoparticle targeting and novel targeting vector exploitation gradually As the research hotspot in antitumor field, occurs a variety of various forms of nano targets at this stage and pass medicine type.

For using liposome as the targeting vector of drug, according to the principle that its targeting plays, ratio is studied to obtain at present More mature is divided into physics targeting and molecular target tropism liposome.Wherein physics targeted hposome includes pH sensitive liposome Body (PLP), photosensitive liposomes, magnetic liposome, thermo-responsive liposome etc..By taking photosensitivity liposome as an example, the benefits such as Yang Peptide pcCPP is permeated with light sensitive cells and contains the short of aspartic-glycine-arginine residues (Asn-Gly-Arg, NGR) Peptide is connected to surface of liposome, constructs pcCPP-NGR-LP, which can promote cellular uptake, and effectively sink Silent c-mycc gene, delays the growth of human fibrosarcoma.However, although above various forms of liposomes add to a certain extent Strong targeting, but still have shortcoming, pH sensitive liposome not can solve the liver and spleen cumulative toxicity problem of liposome.It is photosensitive The problems such as feasible and storage ability discharged with magnetic liposome organism, is still urgently to be resolved.Thermal sensitive liposome can be straight Connect killing tumor cell, but heating time too long causes normal tissue injury.There is also drugs for molecular target tropism liposome Orientation conveying and internal target organ absorption it is bad the problems such as.

To sum up, targeted drug is researched and developed, primarily solves the problems, such as to be exactly that nano-carrier keeps it steady during transportation Determine without being destroyed, (some there may be passive target due to not having active targeting for common nanoparticle or liposome Property), it is easily removed by endothelial system, reduces utilization rate, it is also possible to cause unnecessary toxicity.It secondly is exactly that drug reaches After target cell, by more effective ligand, more rapidly and directly enter the key point that cells play drug effect is research.
