New antibiotics from the fungus Epicoccum nigrum. III. Epicorazine B: structure elucidation and absolute configuration.
Comparison of UV, IR, PMR and CD spectra of epicorazine B with those of epicorazine A, a previously isolated metabolite of Epicoccum nigrum, showed that they were isomers with the sameExpand
Cortalcerone, a new antibiotic induced by external agents in Corticium caeruleum
Abstract The antibacterial compound produced by the fungus Corticium caeruleum in response to external agents was identified as 2-hydroxy-6 H - 3-pyrone-2-carboxaldehyde hydrate, a new compound forExpand
Conversion of glucose to cortalcerone via glucosone by Corticium caeruleum
Abstract Glucose was the sole compound to be converted to cortalcerone by ‘activated’ blue mycelia of Corticium caeruleum ; the first step of this transformation was shown to be the oxidation ofExpand
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-RayExpand
