Total, stereoselective syntheses of the naturally occurring, cytotoxic macrolides aspergillide A and B are described. Olefin metatheses and asymmetric allylations were key steps in the synthetic sequences. Cytotoxicity assays against several tumor cell lines have been performed for the two aspergillides and some of the intermediates or side products of the synthetic sequence. One of these intermediates
描述了天然存在的细胞毒性大环内酯类曲霉内酯A和B的总的立体选择性合成。烯烃复分解和不对称烯丙基化是合成序列中的关键步骤。已经针对两种曲霉内酯和合成序列的一些中间体或副产物进行了针对几种肿瘤细胞系的细胞毒性测定。已发现这些中间体之一对人白血病癌细胞系HL-60具有显着活性,其IC 50值可与临床药物氟达拉滨相媲美。
