A new piperazine-2,5-dione from the marine fungus Gliocladium sp.
A new piperazine-2,5-dione, named gliocladride, was isolated from marine fungus Gliocladium sp. The structure was established on the basis of spectral data, and the stereochemical assignments were made by 1H NMR spectrum and chiral HPLC of the hydrolyzed compound. Gliocladride showed a cytotoxic effect with an IC50 value of 3.86 microg/ml against human A375-S2 melanoma cell line.
