A new manzamine alkaloid, zamamidine D (1), was isolated from an Okinawan Amphimedon sp. marine sponge. The structure of zamamidine D (1) including the relative configuration was elucidated on the basis of spectroscopic data. Zamamidine D (1) is the first manzamine alkaloid possessing a 2,2'-methylenebistryptamine unit as the aromatic moiety instead of a β-carboline unit. Zamamidine D (1) showed antimicrobial activity against several bacteria and fungi.
从冲绳的一种海绵(Amphimedon sp.)中分离出一种新的曼赞明生物碱——扎马米定D(1)。基于光谱数据阐明了扎马米定D(1)的结构,包括其相对构型。扎马米定D(1)是首个以2,2'-亚甲基双色胺单元作为芳香部分而非β-咔啉单元的曼赞明生物碱。扎马米定D(1)对几种细菌和真菌显示出抗菌活性。
