Compounds 2–8, 15, 17, and 18 showed significant inhibitory activities. All the inhibitors were found to be competitive inhibitors, except compound 17, which was a mixed type inhibitor. The substituents (R) in para and ortho positions of phenyl ring B, apparently played a key role in the inhibitory potential of the series. Compounds 1–20 were also studied for their cytotoxicity profile by using 3T3 mouse
苯并咪唑衍生物的文库1 - 20合成,并研究了它们的α胰凝乳蛋白酶(α-CT)的体外抑制活性。进行动力学和分子对接研究以鉴定抑制类型。 与标准的胰凝乳蛋白酶抑制素(IC 50 = 5.7±0.13μM)相比,发现化合物1是α-胰凝乳蛋白酶的良好抑制剂(IC 50 = 14.8±0.1μM,K i = 16.4μM)。化合物2 - 8,15,17,和18显示出显著抑制活性。发现除化合物外,所有抑制剂均为竞争性抑制剂。图17是混合型抑制剂。苯环B对位和邻位的取代基(R)显然在该系列的抑制潜力中起关键作用。化合物1 - 20也通过使用3T3小鼠成纤维细胞研究了它们的细胞毒性曲线和化合物3,5,6,8,12 - 14,16,17,19,和20被发现具有细胞毒性。与标准化合物chymostatin相比,对该系列中最活跃的成员进行了分子对接,以鉴定最可能的结合方式。本文报道的化合物可作为进一步研究
