Abstract:
La tuberculose est une infection humaine cosmopolite à transmission pulmonaire causée par Mycobactérium tuberculosis. Elle représente l'une des principales causes de mortalité dans le monde. La prise en charge thérapeutique de cette maladie est confrontée aujourd’hui à une forte pharmacorésistance des bacilles à la plupart des médicaments antituberculeux habituellement indiqués. Face à cette situation la recherche de nouvelles molécules plus efficaces échappant au phénomène de pharmacorésistance est encouragée par l'OMS. C'est dans ce contexte que nous avons conçu des dérivés de la 1,10-phénan

Abstract:
La tuberculose est une maladie infectieuse extrêmement contagieuse qui dans sa forme simple peut être soignée et guérie. Cependant, des formes multirésistantes aux traitements classiques ont récemment fait leur apparition et le développement de nouvelles molécules constitue donc un enjeu majeur de santé publique. Le 3,3-diméthyl-1,2-dihydro-3H-benzofuro[3,2-f][1]benzopyrane est un produit possédant une activité antituberculeuse marquée, y compris sur des lignées résistantes.
