Abstract

A rapidly increasing number of pyrrole alkaloids (eg 1-4) has been isolated in recent years from marine source^.^-^ Intriguingly, some of these chemically closely related metabolites were found in taxonomically quite distinct organisms such as prosobranch molluscs, ascidians, and sponges collected at remote places in the Indian or Pacific ocean. While for example lukianol A (2) has been found in an unidentified encrusting tunicate collected in ...
