Structures of Antafumicins A and B, Novel Antifungal Substances Produced by the Fungus Aspergillus niger NH-401.
Novel antifungal substances, antafumicins A and B, were isolated from a culture of Aspergillus niger NH-401 and determined to be trans- and cis-4-(3-acetyl-2,6-dihydroxyphenyl)-2-methoxy-4- butanolide, respectively, by spectroscopic and single crystal X-ray analyses.
