In this Letter, we report a convenient and efficient method for the synthesis of new simplified derivatives of hemiasterlin in which the α,α-dimethylbenzylic moiety A is replaced by α,β-unsaturated aryl groups as Michael acceptor. Most of these derivatives have a strong cytotoxic activity on three human tumor cell lines (KB, Hep-G2 and MCF7). Analogs 17b and 17f showed a high cytotoxicity against KB
在这封信中,我们报告了一种方便而有效的方法,用于合成半精胺素的新的简化衍生物,其中α,α-二甲基苄基部分A被α,β-不饱和芳基取代为Michael受体。这些衍生物大多数对三种人类肿瘤细胞系(KB,Hep-G 2和MCF 7)具有很强的细胞毒活性。类似物17b和17f显示出与紫杉醇和玫瑰树碱相当的对KB和Hep-G 2癌细胞系的高细胞毒性。
