Synthesis of a novel biotin-tagged photoaffinity probe for VEGF receptor tyrosine kinases
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.

Novel biotin-tagged photoaffinity probes based on a trifunctional tertiary amine scaffold were synthesized and evaluated as vascular endothelial growth factor receptor-2 (VEGFR-2) inhibitors. Probes 3a–c inhibit VEGF induced proliferation in HUVE cells, with IC50 values of 29.7, 33.3, and 37.7 μM, respectively. Moreover, we identified the interaction of 3b with VEGFR-2 in photoaffinitylabeling experiment
