The molecule is a member of the class of 4-pyridones that is nigerone B in which the nitrogen of the carboxamide has been acylated by a (3S)-3-carboxybutanoyl group. It has been isolated from Aspergillus niger ATCC 1015. It has a role as an Aspergillus metabolite. It is a dicarboximide, a monocarboxylic acid, a member of 4-pyridones and a biaryl. It derives from a nygerone B.
