摘要:
                                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 IC50 value of 7.1 mu M, and inhibits VEGF-induced proliferation in human umbilical vein endothelial cells (HUVEC), with an IC50 value of 40.3 mu M. This probe will be a useful reagent for investigating ligand-protein interactions. (c) 2005 Elsevier Ltd. All rights reserved.
