Abstract[English]
Provided herein is a one-pot method of synthesising a C-nucleoside-5'-monophosphate such as pseudouridine-5' -monophosphate, from an N-nucleoside using a multi-step enzymatic pathway. The method comprises reacting the N-nucleoside with a phosphate source and nucleoside phosphorylase to form a pentose-1-phosphate intermediate, reacting the pentose-1-phosphate intermediate with a phosphomutase to form pentose-5-phosphate intermediate, and reacting the pentose-5-phosphate intermediate with a nucleoside-5'-phosphate C -glycosidase to form the C-nucleoside-5'-monophosphate.[French]
La présente invention concerne un procédé de synthèse en une seule étape d'un C-nucléoside-5'-monophosphate, tel que la pseudouridine-5'-monophosphate, à partir d'un N-nucléoside en utilisant une voie enzymatique à plusieurs étapes. Le procédé consiste à faire réagir le N-nucléoside avec une source de phosphate et une nucléoside phosphorylase pour constituer un intermédiaire pentose-1-phosphate, à faire réagir l'intermédiaire pentose-1-phosphate avec une phosphomutase pour constituer l'intermédiaire pentose-5-phosphate, et à faire réagir l'intermédiaire pentose-5-phosphate avec une nucléoside-5'-phosphate C -glycosidase pour constituer le C-nucléoside-5'-monophosphate.
