has been synthesised and evaluated for their ALK5 inhibitory activity in an enzyme assay and in a cell-based luciferase reporter assay. Incorporation of a quinoxalin-6-yl moiety and a methylene linker at the 4- and 2-position of the imidazole ring, respectively, and a m-CONH2 substituent in the phenyl ring generated a highly potent and selective ALK5 inhibitor 11e.

摘要 合成了一系列2,4-二取代的5-(6-烷基吡啶-2-基)-1 H-咪唑类化合物7a–c,11a–h和16a–h,并在一定条件下评估了它们对ALK5的抑制活性。酶分析和基于细胞的萤光素酶报告基因分析。分别在咪唑环的4-位和2-位引入喹喔啉-6-基部分和亚甲基接头,以及在苯环中引入m- CONH 2取代基,产生了高效的选择性ALK5抑制剂11e。与11e形成复合物的ALK5的对接模型表明,它与ATP结合袋非常吻合,相互作用良好。
