Use of bacterial strains of the species
Amycolatopsis mediterranei
for microbial transformation of 9β,10α-steroids of formula (I) to their corresponding 11β-hydroxyl analogues, as well as specific strains of that species, a process for transforming 9β,10α-steroids to their corresponding 11β-hydroxyl derivatives using bacterials strains of the species
Amycolatopsis mediterranei
, and subsequent isolation of the 11β-hydroxyl derivatives from the bacterial culture medium. The resulting 11β-hydroxylated products are useful intermediates for preparing novel steroidal compounds with 9β,10α-confirmation carrying different kinds of substituents in the 11β-position.
使用地中海链霉菌(Amycolatopsis mediterranei)的细菌菌株对式(I)的9β,10α类固醇进行微生物转化,以得到相应的11β-羟基类似物,该物种的特定菌株,以及使用地中海链霉菌的细菌菌株将9β,10α类固醇转化为相应的11β-羟基衍生物的过程,并从细菌培养基中分离11β-羟基衍生物。由此产生的11β-羟基化产物是制备具有不同11β位置取代基的9β,10α-确认的新型类固醇化合物的有用中间体。
