In this work, incubations of testosterone, dehydroepiandrosterone and pregnenolone with Mucor hiemalis MRC 70325 have been reported. Incubation of testosterone afforded androst-4-en-3,17-dione (3%), 14α-hydroxyandrost-4-en-3,17-dione (9%), 6β-hydroxyandrost-4-en-3,17-dione (2%) and 14α,17β-dihydroxyandrost-4-en-3-one (62%). Incubation of dehy droepiandrosterone afforded 3β,17β-dihydroxyandrost-5-ene (6%) and 3β,7α-dihydroxyandrost-5-en-17-one (72%). Incubation of pregnenolone afforded 3β,14α-dihydroxypregn-5-en-7,20-dione (3%), 3β,7α-dihydroxy-pregn-5-en-20-one (64%) and 3β,7α,11α-trihydroxypregn-5-en-20-one (11%). 3β,14α-Dihydroxypregn-5-en-7,20-dione was identified as a new metabolite.
在这项工作中,报告了睾酮、脱氢表雄酮和孕烯醇酮与 Mucor hiemalis MRC 70325 的孵育情况。睾酮孵育产生雄甾-4-烯-3,17-二酮(3%)、14α-羟基雄甾-4-烯-3,17-二酮(9%)、6β-羟基雄甾-4-烯-3,17-二酮(2%)和 14α,17β-二羟基雄甾-4-烯-3-酮(62%)。孵育去氢表雄酮可得到 3β,17β-二羟基雄甾-5-烯(6%)和 3β,7α-二羟基雄甾-5-烯-17-酮(72%)。孕烯醇酮孵育可得到 3β,14α-二羟基孕甾-5-烯-7,20-二酮(3%)、3β,7α-二羟基孕甾-5-烯-20-酮(64%)和 3β,7α,11α-三羟基孕甾-5-烯-20-酮(11%)。3β,14α-二羟基孕甾-5-烯-7,20-二酮被鉴定为一种新的代谢物。
