    Journal: Mar Drugs; 2017 Jun 09; 15(6):. PubMed ID: 28598397.
    Abstract:
    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.
