New antibiotics from the fungus Epicoccum nigrum. II. Epicorazine A: structure elucidation and absolute configuration.
An antibiotic, epicorazine A, isolated from a particular strain of the fungus Epicoccum nigrum, was shown to be a new epidithiodiketopiperazine from its UV, IR, mass, NMR and CD spectra. X-Ray diffraction measures confirmed this structure and its absolute configuration.
