Abstract
Six novel metabolites, acremines A–F have been isolated from agar cultures of a strain of Acremonium sp. Their structures and stereochemistry were elucidated using a combination of 13C and 1H homo and heteronuclear 2D NMR experiments and X-ray analysis. Acremines A–D inhibited the germination of sporangia of Plasmopara viticola.
