We have developed a series of novel potent ortho-substituted azole derivatives active against kinases VEGFR-1 and VEGFR-2. Both specific and dual ATP-competitive inhibitors of VEGFR-2 were identified. Kinase activity and selectivity could be controlled by varying the arylamido substituents at the azole ring. The most specific molecule (17) displayed > 10-fold selectivity for VEGFR-2 over VEGFR-1. Compound
我们已经开发了一系列对激酶VEGFR-1和VEGFR-2具有活性的新型有效的邻位取代的唑衍生物。确定了VEGFR-2的特异性和双重ATP竞争性抑制剂。激酶活性和选择性可以通过改变唑环上的芳酰胺基取代基来控制。最特异性的分子(17)对VEGFR-2的选择性是对VEGFR-1的10倍以上。在酶促和基于细胞的测定中,化合物的活性处于已报道的临床和开发候选药物(IC50 <100 nM)的活性范围内,包括诺华的PTK787(Vatalanib)。活性化合物跨Caco-2细胞单层的高渗透性(> 30x10(-5)cm / min)指示了口服给药后肠道吸收的潜力。
