isolated from the cyanobacterium Caldora penicillata and contains structural motifs found in promising cancer drug leads. The first total synthesis of 4 and its analogues was achieved, which also enabled a concise formal synthesis of somocystinamide A (3), a dimeric congener of 4 that previously showed extremely potent antiproliferative activities. This work provides further insights on structure–activity
Laucysteinamide A ( 4 ) 是一种从蓝藻Caldora penicillata中分离出来的海洋天然产物,含有在有希望的抗癌药物先导中发现的结构基序。实现了4及其类似物的第一次全合成,这也实现了 somocystinamide A ( 3 ) 的简明形式合成,这是一种4的二聚同源物,以前显示出极强的抗增殖活性。这项工作为此类天然产物的结构-活性关系提供了进一步的见解。
