摘要
目的合成7α-羟基-去氢表雄酮(7α-OH-DHEA),并对其进行活性测定。方法以薯蓣皂苷元为起始原料,用化学法合成DHEA,再用生物转化法合成7α-OH-DHEA。结果经6步化学反应合成得到了DHEA;筛选出一株对DHEA有转化活性的菌株,经鉴定为曲霉(Aspergillus.),利用曲霉对DHEA转化得到了7α-OH-DHEA,收率为35.0%。结论利用生物转化的方法合成7α-OH-DHEA,步骤少,立体选择性好,污染小,目标产物具有好的免疫调节活性。
OBJECTIVE To study the synthesis of 7α-OH-DHEA. METHODS DHEA was synthesized using chemical synthesis with diosgenin as starting material, and the 7α-OH-DHEA was obtained by microbial transformation. RESULTS The strain isolated from samples collected from different area, was identified as Aspergillus. which could translate DHEA into 7α-OH-DHEA, and the yield was 35.0 percent. CONCLUSION Microbial transformation was a good method because of its less steps, small pollution and good stereo-selectivity. The target compound have good immunocompetence.
