Description
Technical field
The present invention relates to pharmaceutical chemistry and therapeutics field, be specifically related to class novel benzimidazoles compounds and uses thereof.
Background technology
Features of tumor is cell or mutant abnormality proliferation, forms lump.Malignant tumour is a kind of common disease and frequently-occurring disease of serious harm HUMAN HEALTH, and caused mortality ratio is second of all disease death rates, is only second to cardiovascular and cerebrovascular diseases.
Along with molecular biological progress, people have had more understanding to synthetic, the function and the regulation and control of gene, protein, cell, and the generation development of tumour has also been had more deep understanding, for the research of antitumour drug provides new action target spot.Along with people to the understanding in depth of tumor vascular growth process, the tumor vessel system has become a treatment target spot brand-new, that be hopeful to be worth.The medicine that suppresses the new vessel generation is called angiogenesis inhibitor (angiogenesis inhibitor), angiogenesis inhibitor not only shows good function of tumor inhibition in the animal experimental model of tumour diffusion and growth, and the multi-drug resistant tumour invalid for traditional chemotherapy provides new methods of treatment, is the impressive progress of 21st century cancer therapy.
Vascular endothelial growth factor (VEGF) is the angiogenic growth factor that present known effect is the strongest, specificity is the highest, and vegf receptor is very little at normal tissue expression, and expressing significantly under pathological conditions increases.Therefore, be that the angiogenesis inhibitor of target spot has the specificity height with the vegf receptor, be difficult for producing resistance, advantage that toxicity is little, become the focus of antitumour drug research and development in recent years.
Vegf receptor belongs to receptor tyrosine kinase (recepter tyrosine kinases, RTKs) superfamily, mainly comprise two acceptors: fms sample acceptor (fms-like tyrosine kinase-1, FLT-1) and contain acceptor (the kinase domain-containing recepter that kinases inserts the territory, KDR), think that at present the main mediated cell skeleton of FLT-1 is reset and caused cell migration, and causes monocyte chemotactic; KDR then mainly mediates endothelial cell proliferation, causes that vascular permeability raises, and has anti-endotheliocyte accent to die, keep endotheliocyte survival effect.Therefore generally believe that KDR is more important in angiogenic action.
Benzimidazoles compound is that a class has extensive bioactive organic heterocyclic molecule, can show good inhibition effect to numerous enzymes, demonstrates potentiality to be exploited and application prospect preferably.In recent years, a large amount of novel benzimidazoles lead compounds with good enzyme inhibition activity constantly are synthesized and find.Present many work have stronger enzyme inhibition activity and all have the developable benzimidazoles enzyme inhibitors of superior performance aspect pharmacokinetics and the selectivity in the hope of obtaining by the structural modification transformation to benzoglyoxaline and derivative thereof.2007, Potashiman group and Hasegawa group reported that respectively the benzimidazoles compound that 2-position acid amides replaces has very strong inhibition activity (J.Med.Chem.2007,50,4453-4470 to vegf receptor; J.Med.Chem.2007,50,4351-4373), it is expected to be developed as the angiogenesis inhibitor series antineoplastic medicament.
The inventor has synthesized a series of new benzimidazoles compounds, through the anti tumor activity in vitro screening, has good antitumor activity.
