Annonaceous acetogenins are a large class of naturally occurring polyketides exhibiting potent anticancer activities. Based on our previous discovery of AA005, a multi-ether mimic of natural acetogenins having potent antitumor activities and significant selectivity between normal cells and cancer cells, a new series of mimics containing a terminal lactam were designed, synthesized and evaluated. Bioactivity
丙酮酸非生成素是一大类天然聚酮化合物,表现出强大的抗癌活性。基于我们先前对AA005的发现,AA005是一种天然的促乙酸素的多醚模拟物,具有有效的抗肿瘤活性,并且在正常细胞和癌细胞之间具有显着的选择性,因此设计,合成和评估了一系列新的包含末端内酰胺的模拟物。针对癌细胞的生物活性研究表明,含N-甲基化内酰胺的化合物3、4和5与AA005相比具有相似的效力,并且对癌细胞具有相似的选择性。通过合成衍生物24-26进一步探索了N-烷基的烃长效应,并研究了该衍生方案在荧光标记中的应用。
