Patent 7727731 was granted and assigned to AB Science on June, 2010 by the United States Patent and Trademark Office.
The present invention relates to a screening method allowing the identification and selection of compounds targeting the transphosphorylase (also called phosphotransferase) domain of c-kit, more particularly compounds selected to be potent inhibitors of constitutively activated c-kit, while being unable to inhibit other activation pathways as for example the pathways leading to death of IL-3 dependent cells cultured in presence of IL-3.
