Title (EN) NOVEL BILE ACID CONVERTING MICROORGANISM AND PROCESS FOR PREPARING BILE ACID
(FR) NOUVEAU MICROORGANISME CONVERTISSANT L'ACIDE BILIAIRE ET SON PROCEDE DE PREPARATION
Abstract: front page image
(EN)A microorganism having a capability of introducing a 7$g(b)-hydroxyl group into a 7-unsubstituted bile acid, and a process for preparing a bile acid having a 7$g(b)-hydroxyl group characterized by bringing the above microorganism into contact with a 7-unsubstituted bile acid to convert the acid to a bile acid having a 7$g(b)-hydroxyl group. The process permits ursodeoxycholic acid useful as a cholagogue and intermediates therefor to be efficiently prepared.
(FR)L'invention concerne un micro-organisme ayant la capacité d'introduire un groupe 7$g(b)-hydroxyle dans un acide biliaire 7-non substitué, et un procédé de préparation d'un acide biliaire possédant un groupe 7$g(b)-hydroxyle. Ce procédé consiste à mettre en contact le micro-organisme avec l'acide biliaire 7-non substitué pour transformer l'acide en un acide biliaire possédant un groupe 7$g(b)-hydroxyle. Ce procédé permet de préparer efficacement l'acide ursodésoxycholique utile comme cholagogue, et ses intermédiaires.
