Herein, a series of novel urea-based benzamide derivatives were designed and synthesized based on the structure-based drug design strategy. The anticancer activities against five human cancer cell lines including HCT116, MDA-MB-231, HeLa, A579 and A375 were evaluated and the preliminary structure-activity relationships were summarized. Among them, compounds 23f and 27f exhibited potent antiproliferative
Poly(ADP-ribose) polymerase-1 (PARP-1) 是负责修复 DNA 单链断裂的 DNA 修复酶的关键成员之一。PARP-1的抑制已被证明是一种通过靶向DNA修复途径选择性杀死肿瘤细胞的有前景的策略。在此,基于基于结构的药物设计策略,设计合成了一系列新型脲基苯甲酰胺衍生物。评价了对HCT116、MDA-MB-231、HeLa、A579和A375等五种人类癌细胞系的抗癌活性,并总结了初步的构效关系。其中,化合物23f和27f对 HCT116 细胞具有有效的抗增殖作用,IC 50值分别为 7.87 μM 和 8.93 μM。此外,两种化合物均表现出优异的 PARP-1 抑制活性,IC 50值分别为 5.17 nM 和 6.06 nM。机理研究表明,23f和27f能有效抑制HCT116细胞的集落形成和细胞迁移。此外,23f和27f可导致细胞周期停滞在G2/M期,并通过
