New N-aryl-N'-2-chloroethylureas (CEUs) with enhanced cytotoxicity were developed as antimitotic agents potentially useful in cancer chemotherapy. Highly potent CEUs were obtained by introduction of a branched alkylating chain, the N'-(1-methyl-2-chloro)ethyl group. Their cytotoxic activity was enantio-dependent and induced through specific alkylation of beta-tubulin, leading to microtubule disruption
具有增强的细胞毒性的新的N-芳基-N'-2-氯乙基脲(CEU)被开发为抗有丝分裂剂,可能在癌症化疗中有用。通过引入支链烷基化链N'-(1-甲基-2-氯)乙基可获得高效CEU。它们的细胞毒活性是对映体依赖性的,并通过β-微管蛋白的特定烷基化诱导,从而导致微管破坏和有丝分裂停滞。总体而言,此处描述的CEU的结构修饰显着改善了它们的β-微管蛋白烷基化动力学。在这个新系列中,CEU 16a和18a显示出与β微管蛋白更快反应有关的增强的抗增殖活性,值得进一步研究作为潜在的抗肿瘤药。
