Investigations of a southern Australian marine sponge, Oceanapia sp., have yielded two new β methyl branched bisthiocyanates, thiocyanatins D 1 (3a) and D2 (3b), along with two new thiocarbamate thiocyanates, thiocyanatins E1 (4a) and E2 (4b). The new thiocyanatins belong to a rare class of bioactive marine metabolite previously only represented by thiocyanatins A-C (1, 2a/b). Structures were assigned on the basis of detailed spectroscopic analysis, with comparisons to the known bisthiocyanate thiocyanatin A (1) and synthetic model compounds (5-7). The thiocyanatins exhibit potent nematocidal activity, and preliminary structure-activity relationship investigations have confirmed key characteristics of the thiocyanatin pharmacophore.
