Two new β-carboline alkaloids, xestomanzamine A (1) and xestomanzamine B (2), and a new manzamine-type alkaloid, manzamine X (3), were isolated as cytotoxic constituents from an Okinawan marine sponge of Xestospongia sp. Another new manzamine-type alkaloid, manzamine Y(4), was isolated from an Okinawan marine sponge of Haliclona sp. The structures of these alkaloids were elucidated on the bases of
两种新的β-咔啉生物碱,xestomanzamine A(1)和xestomanzamine B(2),和一种新的manzamine型生物碱,manzamine X(3),是从冲绳藻的Xestospongia sp。的细胞毒性成分中分离出来的。另一种新的manzamine型生物碱,manzamine Y(4),是从Haliclona sp。的冲绳海洋海绵中分离出来的。在2D-NMR和X射线分析的基础上阐明了这些生物碱的结构。
