New geodiamolides from the sponge Cymbastela sp. collected in Papua New Guinea.
Geodiamolides J-P (11-17) and R (19), eight new cyclic depsipetides, have been isolated from the marine sponge Cymbastela sp. collected in Papua New Guinea. The serine residue in geodiamolides L-P (13-17) and R (19) has not been previously found in this family of compounds.
