The current invention provides urea derivatives, in particular compounds having the core structure heteroaryl-NH-CO-NH-aryl-O- heteroaryl, for use in treating, ameliorating, delaying, curing and/ or preventing a disease or condition associated with muscle cells and/or satellite cells, such as Duchenne muscular dystrophy, Becker muscular dystrophy, cachexia or sarcopenia.

BRAF, a serine/threonine specific protein kinase that is part of the MAPK pathway and acts as a downstream effector of RAS, is a potential therapeutic target in melanoma. We have developed a series of small-molecule BRAF inhibitors based on a 1H-imidazo[4,5-b]pyridine-2(3H)-one scaffold (ring A) as the hinge binding moiety and a number of substituted phenyl rings C that interact with the allosteric binding site. The introduction of various groups on the central phenyl ring B combined with appropriate A- and C-ring modifications afford very potent compounds that inhibit V600EBRAF kinase activity in vitro and oncogenic BRAF signaling in melanoma cells. Substitution on the central phenyl ring of a 3-fluoro, a naphthyl, or a 3-thiomethyl group improves activity to yield compounds with an IC50 of 1 nM for purified V 600EBRAF and nanomolar activity in cells.
