Transformation of lynestrenol (19-nor-17alpha-pregn-4-en-20-yn-17beta-ol) (1) was carried out by incubation with Cunninghamella elegans to obtain 19-nor-17alpha-pregn-4-en-20-yn-3-one-10beta,17beta-diol (2), 19-nor-17alpha-pregn-4-en-20-yn-3-one-6beta,17beta-diol (3), and 19-nor-17alpha-pregn-4-en-20-yn-3beta,6beta,17beta-triol (4). Metabolite 4 was identified as a new compound. These metabolites were structurally characterised on the basis of spectroscopic techniques.
林司特龙(19-去甲-17α-孕甾-4-烯-20-炔-17β-醇)(1)经培养中华被毛孢转化为 19-去甲-17α-孕甾-4-烯-20-炔-3-酮-10β,17β-二醇(2)、19-去甲-17α-孕甾-4-烯-20-炔-3-酮-6β,17β-二醇(3)和 19-去甲-17α-孕甾-4-烯-20-炔-3β,6β,17β-三醇(4)。代谢物 4 被鉴定为一种新化合物。这些代谢物基于光谱技术进行了结构表征。
