studies indicate that the quinazoline scaffold was also acceptable for the block A of class II MET inhibitors. The further pharmacokinetic studies led to the identification of the most promising compound 22a with favorable in vitro potency (MET, IC50 = 9.0 nM), human microsomal metabolic stability (t1/2 = 621.2 min) and oral bioavailability (F = 42%). Moreover, 22a displayed good in vivo antitumor efficacy
作为一种特权的支架,喹唑啉环被广泛用于EGFR抑制剂的开发中,而据报道很少有基于喹唑啉的MET抑制剂。在我们开发新的以MET为靶点的抗癌候选药物的不断努力中,设计,合成了一系列基于喹唑啉的1,6-萘吡啶酮衍生物,并对其生物学活性进行了评估。SAR的初步研究表明,喹唑啉支架对于II类MET抑制剂的A嵌段也是可以接受的。进一步的药代动力学研究导致鉴定出最有前途的化合物22a,具有良好的体外效价(MET,IC 50 = 9.0 nM),人微粒体代谢稳定性(t 1/2 = 621.2分钟)和口服生物利用度(F = 42%)。此外, 22a在MET阳性人胶质母细胞瘤U-87 MG异种移植模型中显示出良好的体内抗肿瘤功效(75 mg / kg中的IR为81%)。这些积极的结果表明22a是潜在的针对MET的新型抗肿瘤药物铅,值得进一步开发。
