Abstract

La présente invention concerne un composé ayant une activité antibactérienne et un de ses dérivés, de manière davantage préférée un composé de nucléoside antibactérien qui peut inhiber l'activité du MraY, afin d'exercer une activité antibactérienne et un dérivé du composé de nucléoside, en particulier un nouveau dérivé de Muraymycine qui est un inhibiteur du MraY. L'invention concerne spécifiquement un nouveau dérivé de Muraymycine ou un de ses sels pharmaceutiquement acceptables. Le composé présente de bonnes propriétés de pénétration intracellulaire et une activité antibactérienne puissante. Le composé présente également une résistance contre les enzymes telles que les estérases présentes dans le sang. Un mode de réalisation préféré du composé présente une activité inhibitrice du MraY. Le mode de réalisation préféré du composé est efficace contre les bactéries résistantes telles que les VRE et MRSA.
