A series of 4(5)-(6-alkylpyridin-2-yl)imidazoles 13a-p, 17a, and 17b have been synthesized and evaluated for ALK5 inhibitory activity in an enzyme assay and in cell-based luciferase reporter assays. The quinoxalinyl analogue 13e inhibited ALK5 phosphorylation with an IC50 of 0.012 muM and showed more than 90% inhibition at 0.05 muM in a luciferase reporter assay using HaCaT cells transiently transfected
已经合成了一系列4(5)-(6-烷基吡啶-2-基)咪唑13a-p,17a和17b,并在酶测定法和基于细胞的萤光素酶报告基因测定法中评估了ALK5抑制活性。喹喔啉基类似物13e抑制ALK5磷酸化,IC50为0.012μM,在萤光素酶报告基因测定中,使用瞬时转染了p3TP-luc报告基因构建体的HaCaT细胞,在0.05μM处显示90%以上的抑制作用。通过柔性对接研究生成的13e的结合模式表明13e通过形成几个紧密的相互作用而很好地适合于ALK5的活性位点腔。
