چکیده

Trichodermanins C-E (1-3), new diterpenes with a rare fused 6-5-6-6 ring system, have been isolated from a fungus Trichoderma harzianum OUPS-111D-4 separated from a piece of a marine sponge Halichondria okadai, and these chemical structures have been established by spectroscopic analyses using IR, MASS, HRFABMS, and NMR spectra. We established their absolute stereostructures by application of the modified Mosher's method. In addition, 1 inhibited the growth of cancer cell lines potently.

Austalides S-U, New Meroterpenoids from the Sponge-Derived Fungus Aspergillus aureolatus HDN14-107

Three new meroterpenoids, named austalides S-U (1-3), were isolated from the culture of a sponge-derived fungus Aspergillus aureolatus HDN14-107, together with eleven known austalides derivates (4-14). Their structures, including absolute configurations, were assigned on the basis of NMR, MS data, and TDDFT ECD calculations. Compound 1 is the first case of austalides with the terpene ring fused...
