In this work, a series of novel benzimidazole derivatives were designed and synthesized as Pin1 inhibitors. Protease-coupled assay was used to investigate the Pin1 inhibitory potency of all synthesized compounds. Thirteen of them showed preferable Pin1 inhibitory effects with IC50 values lower than 5 μM, and 12a, 15b, 15d and 16c exhibited the most promising Pin1 inhibitory activity at low micromolar
在这项工作中,设计并合成了一系列新型的苯并咪唑衍生物作为Pin1抑制剂。蛋白酶偶联测定用于研究所有合成化合物的Pin1抑制能力。其中有13个显示出较好的Pin1抑制作用,IC50值低于5μM,并且与阳性对照化合物Juglone相比,在低微摩尔水平(0.33-1.00μM)下,12a,15b,15d和16c表现出最有希望的Pin1抑制活性。流式细胞仪结果表明,用16c处理PC-3细胞会引起浓度依赖性的轻微周期停滞。详细分析了苯并咪唑衍生物的R1,R2,R3和连接基的构效关系,这将有助于进一步探索新的Pin1抑制剂。
