series of N-aryl-N'-(2-chloroethyl)ureas (CEUs) and derivatives were synthesized and evaluated for antiproliferative activity against a wide panel of tumor cell lines. Systematic structure--activity relationship (SAR) studies indicated that: (i) a branched alkyl chain or a halogen at the 4-position of the phenyl ring or a fluorenyl/indanyl group, (ii) an exocyclic urea function, and (iii) a N'-2-chloroethyl
合成了一系列的N-芳基-N'-(2-氯乙基)脲(CEU)及其衍生物,并评估了其对多种肿瘤细胞系的抗增殖活性。系统结构-活性关系(SAR)研究表明:(i)苯环或芴基/茚满基4位上的支链烷基链或卤素,(ii)外环脲官能团,和(iii) )需要N'-2-氯乙基部分以确保明显的细胞毒性。诸如免疫荧光显微镜等生物学实验证实,这些有前途的化合物通过β-微管蛋白的选择性烷基化诱导微管解聚,从而改变了细胞骨架。随后的评估表明,有效的CEU是弱烷基化剂,是非DNA破坏剂,并且不与谷胱甘肽或谷胱甘肽还原酶的硫醇功能相互作用。因此,CEU是新型抗有丝分裂剂的一部分。最后,在评估的一系列CEU中,选择了化合物12、15、16和27用于进一步的体内试验。
