Two pregnane steroids, pregnane (1) and 3β-hydroxypregnane (2), were oxidized by fermentation with the fungus Cephalosporium aphidicola. The fermentation of pregnane (1) yielded 3β-hydroxypregnane (2) and 3β, 6β,11α-trihydroxypregnane (3), while that of 3β-hydroxypregnane (2) afforded 6β,11α-dihydroxypregn-3,20-dione (4), 3β,6β,15α-trihydroxypregn-20-one (5) and 3β,5α,11α-trihydroxypregn-20-one (6). The metabolites are characterized by detailed physical and spectroscopic studies.
两种孕烷类固醇,孕烷(1)和3β-羟基孕烷(2),通过真菌头孢虫蚜菌的发酵作用被氧化。 孕烷(1)的发酵作用产生了3β-羟基孕烷(2)和3β, 6β,11α-三羟基孕烷(3),而3β-羟基孕烷(2)的发酵作用则产生了6β,11α-二羟基孕-3,20-二酮(4)、3β,6β,15α-三羟基孕-20-酮(5)和3β,5α,11α-三羟基孕-20-酮(6)。 通过详细的物理和光谱研究,确定了这些代谢产物的特征。
