From the ocean: Ammosamides A (1) and B (2) were isolated from a marine‐derived Streptomyces species collected in the Bahamas. The structures of these chlorinated tricyclic pyrroloquinoline alkaloids were solved using X‐ray crystallographic techniques. Ammosamide A (1) was shown to contain an unusual thio‐γ‐lactam ring. Both metabolites show specific nanomolar cytotoxicity against selected cancer cell
来自海洋:氨酰胺 A ( 1 ) 和 B ( 2 ) 从在巴哈马收集的海洋来源的链霉菌属物种中分离出来。使用 X 射线晶体学技术解析了这些氯化三环吡咯并喹啉生物碱的结构。Ammosamide A ( 1 ) 被证明含有一个不寻常的硫代-γ-内酰胺环。两种代谢物都对选定的癌细胞系显示出特定的纳摩尔级细胞毒性。
