of a variety of dysfunctions in female and male health,1 as well as an intermediate in the synthesis of steroidal drugs, such as abiraterone acetate which is used for the treatment of prostate cancer.2−4 In this manuscript we describe a novel, concise, and cost-efficient route toward DHEA (2) and DHEA acetate (3) from 4-androstene-3,17-dione (4-AD, 1). Crucial to success was the identification of a
脱氢表雄酮(DHEA,2)是哺乳动物中一种重要的内源性类固醇激素,可用于治疗男女健康中的各种功能障碍1,也是合成甾体药物(如醋酸阿比特龙)的中间体2-4。在本手稿中,我们描述了一种新颖,简洁且经济高效的途径,可从4-雄甾烯3,17-二酮(4-AD,4)转化为DHEA(2)和DHEA乙酸盐(3)。1)。成功的关键是从维氏鞘氨醇单胞菌中鉴定出一种酮还原酶,该酶可将5-雄甾烯-3,17-二酮(5)的C3-羰基高度区域和立体选择性还原为所需的3β醇(2,> 99%de)。该酶在高底物浓度(最高150 g / L)下显示出出色的鲁棒性和溶剂稳定性。
