of N-phenyl-N'-(2-chloroethyl)ureas (CEUs) as potential antineoplastic agents, we investigated the effect of carbonylated substituting chains of the aromatic ring of CEU on their covalent binding to the colchicine-binding site (C-BS). In this study, we found that CEU, 5e, 5f, 8e, and 8f substituted by either a methyl ester or a methyl ketyl group at the omega-position exhibited a significant antiproliferative
在开发N-苯基-N'-(2-氯乙基)脲(CEUs)作为潜在的抗肿瘤药的过程中,我们研究了CEU芳环的羰基取代链对它们与秋水仙碱的共价结合的影响。结合位点(C-BS)。在这项研究中,我们发现在ω-位被甲基或甲基酮基取代的CEU,5e,5f,8e和8f对HT-29,M21和MCF-7肿瘤表现出显着的抗增殖活性细胞。SDS-PAGE分析和细胞周期分析证实5e,5f,8e和8f与C-BS共价结合,并使细胞分裂停滞在G(2)/ M期。令人惊讶地,ω-羧基,ω-乙基酯或ω-酰胺的存在显着降低了抗增殖活性和对β-微管蛋白的特异性。
