title: Synthesis of a novel biotin-tagged photoaffinity probe for VEGF receptor tyrosine kinases.
abstract: A novel biotin-tagged photoaffinity probe was synthesized and evaluated as a vascular endothelial growth factor receptor-2 (VEGFR-2) tyrosine kinase inhibitor. The probe (2) is a potent VEGFR-2 inhibitor with an IC(50) value of 7.1 microM, and inhibits VEGF-induced proliferation in human umbilical vein endothelial cells (HUVEC), with an IC(50) value of 40.3 microM. This probe will be a useful reagent for investigating ligand-protein interactions.
