Technical Field
The invention relates to dioxane chinazoline and dioxane quinoline compounds, pharmaceutically acceptable salts, isomers, hydrates, solvates or prodrugs thereof, and a preparation method and application thereof.
Background
Receptor Tyrosine Kinases (RTKs) span the cell membrane and affect the transmission of biochemical signals across the cell membrane, and consist of an extracellular domain containing a ligand binding site, a single transmembrane domain, and an intracellular domain containing tyrosine protein kinase activity. Binding of the ligand to the receptor stimulates receptor-associated tyrosine kinase activity, which leads to phosphorylation of tyrosine residues on the receptor and other intracellular molecules, which in turn initiates a cascade of signals leading to a variety of cellular responses. The overexpression of the tyrosine receptor activates a downstream signal transduction pathway, finally leads to the abnormal transformation and proliferation of cells, and promotes the generation and development of tumors.
VEGFR (vascular endothelial growth factor) is one of receptor tyrosine kinase families, and a series of biochemical and physiological processes are generated by combining with VEGF (vascular endothelial growth factor) serving as a ligand of VEGFR, so that new blood vessels are finally formed. The generation of tumor vessels and their permeability is mainly regulated by Vascular Endothelial Growth Factor (VEGF), which acts via at least two different receptors (VEGFR-1, VEGFR-2). Studies according to Jakeman, Kolch, Connolly et al show that: VEGF is an important stimulator of normal and pathological angiogenesis and vascular permeability (Jakeman et al, 1993, Endocrinology 133: 848-859; Kolch et al, 1995, Breast Cancer Research and Treatment, 36: 139-155; Connolly et al, 1989, J.biol.chem.264: 20017-20024). Vascular endothelial cell growth factor induces the angiogenic phenotype by inducing endothelial cell proliferation, protease expression and migration and subsequent formation of capillary cellular tissue. Thus, antagonism of VEGF by chelation of VEGF by antibodies can lead to inhibition of tumor growth (Kim et al, 1993, Nature 362: 841-844).
Since VEGFR-2 is mainly distributed in vascular endothelial cells, it can bind to VEGF-A, VEGF-C, VEGF-D, VEGF-E. The effects of VEGF in stimulating endothelial cell proliferation, increasing vascular permeability and neovascularization are primarily achieved by binding to and activating VEGFR-2. If the activity of VEGFR-2 is blocked, the growth and metastasis of tumor can be inhibited through direct and indirect ways, and further the ideal anti-tumor effect is achieved. Therefore, the search for small molecule inhibitors with high activity and selectivity for VEGFR-2 is a promising strategy for tumor therapy.
The hepatocyte growth factor receptor (c-MET) is one of the tyrosine kinase receptors, and its abnormal activation plays an important role in the development and progression of various malignancies, including lung cancer. Hepatocyte Growth Factor (HGF) is a specific ligand of c-MET, and after being combined with HGF, the c-MET plays a biological role through an HGF/c-MET signal channel. The HGF/c-MET signal channel can induce a series of biological effects of cell proliferation, dispersion, migration, organ morphogenesis, angiogenesis and the like. Aberrant activation of c-MET may manifest as receptor overexpression, gene mutation, amplification, ectopy, rearrangement, and the like. These changes can lead to down-stream signaling pathway disorders such as serine/threonine protein kinase (AKT), extracellular signal kinase (ERK), phosphatidylinositol-3-hydroxykinase, retinoblastoma inhibitory protein (Rb) pathway, and the like, mediating processes such as tumorigenesis, invasion and metastasis, angiogenesis, epithelial-mesenchymal transition, and the like. c-MET plays an important role in cell proliferation, metabolism, tumor production, metastasis, and angiogenesis, and has become an important target for anti-tumor therapy. The targeted therapy targeting c-MET has shown its important implications in the treatment of a variety of malignancies, including lung cancer.
RET is also a transmembrane receptor tyrosine kinase that is essential for normal development of tissues such as the brain, nervous system, thyroid and lung. Activating mutations and oncogenic fusions of receptor tyrosine kinases have been found in a variety of tumor types, including thyroid, lung, breast and colon cancers. At present, no drug which takes RET as a specific target point is on the market, so that the development of a small molecule inhibitor aiming at RET has extremely high application value.
During the treatment process of using the antitumor drug, the interaction of multiple signal pathways can influence the action effect of the antitumor drug, for example, the interaction of the HFG/c-MET signal pathway and other pathways influences the treatment effect of the antitumor drug, and drug resistance is generated. Therefore, the multi-kinase target combined drug becomes a new anti-tumor treatment means, and the successful marketing of Crizotinib and Cabozantinib indicates that the development of the multi-kinase target inhibitor has good potential and application value.
Cabozantinib is a small molecule inhibitor of protein kinase, and has inhibitory effect on various kinases such as c-MET, VEGFR-2, Ret, Kit, AXL, etc. Cabozantinib can inhibit phosphorylation of c-MET and VEGFR-2 in tumor model, and shows effective anti-tumor metastasis and anti-angiogenesis activity in preclinical drug effect model. No increase in tumor burden was observed in the pulmonary tumor metastasis model treated with Cabozantinib compared to inhibitors acting on VEGFR targets alone, suggesting that Cabozantinib is a potent inhibitor of tumor angiogenesis and metastasis in tumor patients with dysregulated c-MET and VEGFR-2 signaling pathways. The FDA approved Cabozantinib for marketing on day 29/11 of 2012 for the treatment of patients with progressive, metastatic Medullary Thyroid Carcinoma (MTC).
Inhibitors that act on multiple targets like Cabozantinib have many advantages, and studies on this type of inhibitor are also very hot. The medicines on the market at present are few, the available channels are limited, and the medicines on the market have the problems of drug resistance, side effects and the like in use. Therefore, compared with the single-target inhibitors which are already on the market, the multi-target small molecule inhibitor has better treatment effect and application prospect.
