Title: Microbial transformation of (+)-androsta-1 ,4-diene-3,17-dione by Cephalosporium aphidicola. Author: Choudhary MI, Musharraf SG, Shaheen F, Atta-Ur-Rahman. Journal: Nat Prod Lett; 2002 Dec; 16(6):377-82. PubMed ID: 12462341. Abstract: Fermentation of (+)-androsta-1,4-diene-3,17-dione ([structure: see text]) with Cephalosporium aphidicola for 8 days yielded oxidative and reductive metabolites, androst-4-ene-3,17-dione ([structure: see text]), 17beta-hydroxyandrosta-1,4-diene-3-one ([structure: see text]), 11alpha-hydroxyandrosta-1,4-diene-3,17-dione ([structure: see text]), 11alpha-hydroxyandrost-4-ene-3,17-dione ([structure: see text]), 11alpha,17beta-dihydroxyandrost-4-ene-3-one ([structure: see text]) and 11alpha,17beta-dihydroxyandrosta-1,4-diene-3-one ([structure: see text]). The fermentation of [structure: see text] with Fusarium lini also yielded metabolites [structure: see text]. The structures of these metabolites were elucidated on the basis of spectroscopic techniques.[Abstract] [Full Text] [Related] [New Search]
