Identification of potent and selective VEGFR receptor tyrosine kinase inhibitors having new amide isostere headgroups

A novel series of malonamide-type dual VEGFR2/c-Met inhibitors in which one of the amide bonds was replaced by an amide isostere-a trifluoroethylamine unit, was designed, synthesized, and evaluated for their enzymatic and cellular inhibition of VEGFR2 and c-Met enzymes. Optimization of these molecular entities resulted in identification of potent and selective inhibitors of VEGFR2 enzyme. (C) 2010 Elsevier Ltd. All rights reserved.
