Furanone, morpholinone and tetrahydrofuran derivatives from the marine-derived fungus sp. PSU-MF07.

Three new compounds including one furanone, one morpholinone and one tetrahydrofuran together with three known compounds were isolated from the broth extract of the marine-derived fungus sp. PSU-MF07. The structures of the isolated compounds were determined on the basis of spectroscopic methods.

-Pyrone and decalin derivatives from the marine-derived fungus PSU-MF79.

Two new compounds, one -pyrone (trichoharzianone) and one decalin (trichoharzianin), along with eight known compounds including three decalins, two -lactones, two carboxylic acids and one isochroman were isolated from the marine-derived fungus PSU-MF79. The structures were determined by spectroscopic methods. The relative configuration of trichoharzianin was assigned based on NOEDIFF data and coupling constants whereas the absolute configurations were established by comparison of electronic circular dichroism data with those of the co-metabolites.
