T1 - Detection of a Toxic Methylated Derivative of Phomopsin A Produced by the Legume-Infesting Fungus Dioporthe toxica N2 - Phomopsin A (PHO-A), produced by the fungus Diaporthe toxica, is a mycotoxin known to be responsible for fatal liver disease of lupin-fed sheep. The füll spectrum of the toxic secondary metabolites produced by D. toxica is still unknown. PHO-A and the naturally occurring derivatives B—E have been subject to several studies to reveal their structures as well as chemical and toxicological properties. In this work, a methylated derivative of PHO-Aisolated firom lupin seeds inoculated %vith D. toxica is described. It was characterized by high-resolution mass and NMR data and shown to be the N-methylated derivative of PHO-A 1 is cytotoxic againstHepG2 cells.
