Syntheses of 16-membered macrolactams, which were aza-analogues of macrosphelides, could be established effectively by a ring-closing metathesis (RCM) strategy. Novel 19 analogues and six aza-macrosphelide–epothilone hybrids were furnished according to simple operations. Biological assay of these artificial aza-macrosphelides revealed that some of them showed stronger apoptosis-inducing activity against
通过闭环易位(RCM)策略可以有效地建立16元大内酰胺的合成,这是大环内酯的氮杂类似物。根据简单的操作,提供了新颖的19种类似物和6种氮杂-大环内酯-埃博霉素的杂种。这些人造的氮杂-大环内酯类化合物的生物学分析表明,其中一些比母体化合物对人淋巴瘤细胞表现出更强的凋亡诱导活性。
