摘要：

Anthosamines A and B (1 and 2), new pipecolate derivatives have been isolated as metamorphosis-inducers of ascidian Halocynthia roretzi larvae from a marine sponge Anthosigmella aff. raromicrosclera, along with a new diketopiperazine 3, cyclo-(L-Arg-dehydrotyrosine). Their structures were elucidated on the basis of spectral data. Reversible isomerization between amine and iminium ion forms were observed for 1 and 2; iminium ion forms (1b and 2b) predominate in protic solvent, amine forms (1a and 2a) in aprotic solvent.
