A novel butenoate derivative from Aspergillus niger

Abstract

A novel butenoate derivative, methyl (Z)-4-{[(Z)-1-(hydroxymethyl) -2-phenyl-1-ethenyl] amino}-4-oxo-2-butenoate (1), was isolated from the fermentation broth of an Aspergillus niger strain Ta1. The structure (1) was elucidated by spectral analysis. Bioassays showed that compound 1 had a weak antioxidant activity. © 2006 Taylor & Francis.
