摘 要:7α,15α-二羟基雄烯醇酮1是合成口服避孕药Yasmin活性成分屈螺酮的重要中间体,应用亚麻刺盘孢(Colletotrichum lini AS 3.4486)的羟化酶系统对去氢表雄酮底物进行生物转化,合成了7α,15α-二羟基雄烯醇酮,转化率60~70%。转化机理研究发现,亚麻刺盘孢将底物的7位羟基化合成7α-羟基雄烯醇酮,再将其15位羟基化形成双羟基的产物。亚麻刺盘孢菌能够特异性、有序地完成对去氢表雄酮的两步羟化反应,与文献报道的结论一致,间接转化方法和转化机理属于首次报道。7α, 15α-dihydroxyandrostenolone is an important intermediate for synthesizing the drospirenone active ingredient of an oral contraceptive, Yasmin. It was obtained by bio-transforming androstenolone using Col-letotrichum lini AS 3.4486 in a yield of 60-70%. The study on the bio-transformation mechanism found that androstenolone was first transformed into 7α-hydroxy androstenolone, which then underwent 15β-hydrolation to produce the final product. This result suggested that C. lini AS 3.4486 can carry out two steps of hydroxylation reactions of androstenolone in a selective and sequential manner.
