protease, is upregulated in prostate cancer and known to be involved in the progression of metastasis. Here we report a structure-guided approach, which resulted in the discovery of 2-aryl/pyridin-2-yl-1H-indole derivatives as potent and selective inhibitors of hepsin. Potent and selective inhibition of hepsin by compound 8 is likely due to interactions of the amidine group at the S1 site with the cyclohexyl
Hepsin是一种II型跨膜丝氨酸蛋白酶,在前列腺癌中上调,并且已知与转移的进展有关。在这里我们报告了一种结构指导的方法,该方法导致发现了2-芳基/吡啶-2-基-1 H-吲哚衍生物作为肝素的有效抑制剂和选择性抑制剂。化合物8对hepsin的有效抑制作用可能是由于S1位的the基与2-芳基向S1'位突出的环己基环以及叔羟基与His57侧链相互作用造成的。如X射线晶体学所揭示。化合物8和10,显示出ķ我对于hepsin而言,其为0.1μM,并且表现出对hepsin过表达细胞系的侵袭和迁移的抑制。本文描述的化合物可以用作有用的工具试剂,以研究肝素作为癌症潜在治疗靶标的作用。
