A new series of 10-demethoxy-10-methylaminocolchicines bearing urea, thiourea or a guanidine moieties at position C7 has been designed, synthesized and evaluated for in vitro anticancer activity against different cancer cell lines (A549, MCF-7, LoVo, LoVo/DX). The majority of the new derivatives were active in the nanomolar range and were characterized by lower IC50 values than cisplatin or doxorubicin
一系列新的10-去甲氧基-10- methylaminocolchicines轴承脲,硫脲或一个 在位置C7胍基部分已经被设计,合成并评价在体外对不同癌细胞系A549,MCF-7,株LoVo,株LoVo抗癌活性(/ DX)。大多数新衍生物的活性在纳摩尔范围内,其特征是 IC 50值低于顺铂或多柔比星。发现两种尿素(4和8)和硫脲(19和25)是良好的抗增殖剂(低 IC 50 ) 值和高 SI),并可能被证明是基于秋水仙碱骨架的抗癌药物领域进一步研究的有希望的候选者。
