Ptilomycalin D, a polycyclic guanidine alkaloid from the marine sponge Monanchora dianchora.
A new polycyclic guanidine alkaloid, ptilomycalin D, and the known crambescidic acid were isolated from the marine sponge Monanchora dianchora collected in Nosy-Be, northwest of Madagascar, in the Indian Ocean. The structures were elucidated using 1- and 2-D NMR and MS data, and their biogenetic implications are discussed.
