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.

[EN] The invention relates to the use of bacterial strains of the species Amycolatopsis mediterranei for the microbial transformation of 9ß,10a-steroids of general Formula (I) to their corresponding 11ß-hydroxyl analogues, as well as to specific strains of that species. In addition, the present invention relates to the process of transforming 9ß,10a-steroids to their corresponding 11ß-hydroxyl derivatives using bacterials strains of the species Amycolatopsis mediterranei, and to the subsequent isolation of the 11ß-hydroxyl derivatives from the bacterial culture medium. The resultant 11ß-hydroxylated products are useful intermediates for the preparation of novel steroidal compounds with 9ß,10a-confirmation carrying different kind of substituents in the 11ß-position. [FR] La présente invention concerne l'utilisation de souches bactériennes de l'espèce Amycolatopsis mediterranei pour la transformation microbienne de stéroïdes 9ß,10a de formule générale (I) en leurs analogues 11ß-hydroxyle correspondants, ainsi que des souches spécifiques de cette espèce. L'invention concerne également un procédé de transformation des stéroïdes 9ß,10a en leurs dérivés 11ß-hydroxyle correspondants en utilisant des souches bactériennes de l'espèce Amycolatopsis mediterranei et l'isolement ultérieur des dérivés 11ß-hydroxyle à partir du milieu de culture bactérien. Les produits hydroxylés en 11ß résultants sont des intermédiaires utilisables dans la préparation de composés stéroïdiens innovants avec une confirmation 9ß,10a portant divers types de substituants en position 11ß.
