Fermentation of a marine fungal species obtained from a tissue sample of a
marine sponge collected in Indonesia in October 1996, yielded the novel hex
aketide compounds iso-cladospolide B (1); seco-patulolide C (2); the 12-mem
bered macrolides, pandangolide 1 (3) and pandangolide 2 (4); and the known
terrestrial fungal metabolite, cladospolide B (5).
