title: Ceratamines A and B, antimitotic heterocyclic alkaloids isolated from the marine sponge Pseudoceratina sp. collected in Papua New Guinea.
abstract: [structure: see text] Two novel antimitotic heterocyclic alkaloids, ceratamines A (1) and B (2), have been isolated from the marine sponge Pseudoceratina sp., collected in Papua New Guinea. The structures of 1 and 2 were elucidated by analysis of spectroscopic data.
