Scientific summary

The strategy we investigated to treat Duchenne muscular dystrophy (DMD) is to associate the benefits of an over-expression of utrophin, a “foetal” autosomal homolog of dystrophin, the lacking protein in DMD, with an activation of satellite cells, a reduction of the inflammation process in muscles and a vasodilatation effect for an effective supply of metabolites and oxygen to the working muscle. For this purpose we have developed drugs which combine two key pharmacological activities, i.e., nitric oxide pathway activation and histones deacatylase inhibition. The beneficial effects of the association of arginine (the substrate of nitric oxyde synthase (NO)) and butyrate (an inhibitor of histone deacetylase) are tested in mdx mice (the animal model for DMD)and in human cell cultures of myotubes.
The data are protected by two patents.
Toxicology studies have been performed by a partner.
