Abstract: We report here a fragment screen directed toward the c-MET kinase from which we discovered a series of inhibitors able to bind to a rare conformation of the protein in which the P-loop adopts a collapsed, or folded, arrangement. Preliminary SAR exploration led to an inhibitor (7) with nanomolar biochemical activity against c-MET and promising cell activity and kinase selectivity. These findings increase our structural understanding of the folded P-loop conformation of c-MET and provide a sound structural and chemical basis for further investigation of this underexplored yet potentially therapeutically exploitable conformational state.
