RESUMO
Various species of Absidia, Aspergillus, Cunninghamella, Trichothecium, Penicillium, and Phanerochaete were found to transform rotenone to one or more metabolites. Two biotransformation products were isolated from a preparative-scale incubation of rotenone with Cunninghamella blakesleeana and identified as 1′,2′-dihydro-1′,2′-dihydroxyrotenone and 3′-hydroxyrotenone (amorphigenin). The catalytic reduction of the isopropylene side chain of rotenone resulted in the formation of 1′,2′-dihydrorotenone. The latter was transformed by C. blakesleeana to 2′-hydroxy-1′,2′-dihydrorotenone.
