Degradation of 3,9-Dimethoxypterocarpan and Medicarpin by Fusarium proliferatum

Abstract

Abstract The degradation of 3,9-dimethoxypterocarpan was investigated in selected strains of Fusarium. Fusarium proliferatum (i. e. Gibberella fujikuroi (SAW)WR) degrades this substrate via 3-meth-oxy-9-hydroxypterocarpan, 3,9-dihydroxypterocarpan and 2',4',7-trihydroxyisoflavan. During degradation by this organism medicarpin is first demethylated to 3,9-dihydroxypterocarpan.
