Two marine sponges of the genus Monanchora (Poecilosclerida, Crambeidae) have been found to contain new polycyclic guanidine alkaloids bearing the (5,6,8b)-triazaperhydroacenaphthylene skeleton. Their structures have been determined by detailed spectroscopic analysis. Dehydrobatzelladine C (1) has been isolated from M. arbuscula and crambescidins 359 (2) and 431 (3) from M. unguiculata. The chemotaxonomic implications of these findings are discussed.
已发现两种单锚海绵属（Poecilosclerida目，Crambeidae科）的海洋海绵含有带有(5,6,8b)-三氮杂氢化苊骨架的新型多环胍生物碱。通过详细的光谱分析确定了它们的结构。脱氢巴泽拉定C（1）从丛状单锚海绵中分离得到，而crambescidin 359（2）和431（3）则从未端单锚海绵中分离得到。讨论了这些发现的化学分类学意义。
