Abstract

FLT3 kinase inhibitors are currently under investigation as a new treatment for acute myeloid leukemia. We report here a molecular concept invoking interactions between an aromatic ring and the side chains of Phe691 and Cys828, two residues of the ATP pocket, to obtain potent and specific inhibitors of this kinase. The hypothesis has been validated by the successful design of a new inhibitor prototype showing promising antiproliferative activity in cellular assays.
