Abstract
|
|
|
A chemical analysis of the fermentation of the marine-derived fungus Penicillium sp. led to the isolation of a biogenetic precursor of citrinin, redoxcitrinin (1), together with polyketide mycotoxins, phenol A (2), citrinin H2 (3), 4- hydroxymellein (4), citrinin (5), and phenol A acid (6). The structures of compounds 1-6 were determined on the basis of physicochemical data analyses. Among them, compounds 1- 3 exhibited a potent radical scavenging activity against 1,1- diphenyl-2-picrylhydrazyl (DPPH) with IC50 values of 27.7, 23.4, and 27.2 ¥ìM, respectively
