A sequence of coumarin analogs 5a–j was obtained by multi step synthesis from hydroxy benzophenones (1a–j). The in vitro antiproliferative effect of the title compounds was tested against Ehrlich ascites carcinoma (EAC) and Daltons lymphoma ascites (DLA) cell lines. Among the series, compound 5c with bromo group in the benzophenone moiety was endowed with excellent antiproliferative potency with significant
通过多步合成从羟基二苯甲酮(1a – j)获得了香豆素类似物5a – j的序列。在体外的标题化合物的抗增殖作用是对艾氏腹水癌(EAC)和道尔顿淋巴瘤腹水(DLA)细胞系进行测试。在该系列中,在二苯甲酮部分中具有溴基的化合物5c具有出色的抗增殖潜能,IC 50值很高。此外,化合物5c对鼠EAC和实体DL肿瘤模型系统的体内抗肿瘤作用通过延长的存活期得到证实。复方的抑瘤机制5c是由于抗血管生成和促进细胞凋亡。这些结果表明化合物5c的可能应用,其可以在不久的将来被开发为有效的抗癌药。
