To identify novel c‐Met inhibitors, sequences and crystal structures of the human kinome were analyzed to find interesting hinge binders that have been underexplored within the tyrosine kinase subfamily. Through this study, the imidazolopyridine ring was selected as a novel c‐Met hinge‐binding inhibitor scaffold. A series of derivatives was prepared, and the structure–activity relationships were studied
为了鉴定新型的c-Met抑制剂,分析了人类kinome的序列和晶体结构,以发现在酪氨酸激酶亚家族中未得到充分研究的有趣的铰链结合剂。通过这项研究,咪唑并吡啶环被选作新型c-Met铰链结合抑制剂支架。制备了一系列衍生物,并研究了结构-活性关系。其中,一种化合物尤其在酶和细胞分析中表现出出色的活性,良好的体外代谢稳定性和良好的药代动力学参数。口服给药时,该化合物在NIH-3T3 / TPR-Met异种移植模型中抑制肿瘤生长,并且对体重没有不利影响。
