Optimization of the screening hit 1 led to the identification of novel 1,5-naphthyridine aminothiazole and pyrazole derivatives, which are potent and selective inhibitors of the transforming growth factor-beta type I receptor, ALK5. Compounds 15 and 19, which inhibited ALK5 autophosphorylation with IC50 = 6 and 4 nM, respectively, showed potent activities in both binding and cellular assays and exhibited
筛选命中1的优化导致鉴定了新型1,5-萘啶氨基噻唑和吡唑衍生物,它们是转化生长因子βI型受体ALK5的有效抑制剂。分别以IC50 = 6和4 nM抑制ALK5自磷酸化的化合物15和19在结合和细胞分析中均显示出强大的活性,并显示出超过p38促分裂原活化蛋白激酶的选择性。描述了与人ALK5结合的19的X射线晶体结构,证实了对接研究提出的结合模式。
