Synthesis and biological evaluation of benzamides and benzamidines as selective inhibitors of VEGFR tyrosine kinases
摘要:
A series of benzamidines and benzamides was synthesized as selective inhibitors of vascular endothelial growth factor receptor (VEGFR) tyrosine kinases, and tested for inhibitory activity toward autophosphorylation by the enzyme assay. Selective inhibition of VEGFR-2 tyrosine kinase was observed in the salicylic amide 4e and the anthranilic amidine 5a, and their percent inhibitions of VEGFR-2 tyrosine kinase were 44-60% at a 10 mu M concentration of compounds. The salicylic amide 4a showed inhibition of both VEGFR-1 and VEGFR-2 tyrosine kinases at a 10 mu M concentration. (c) 2006 Elsevier Ltd. All rights reserved.

palladium-catalyzed remote meta-C–H functionalization of aromaticaldehydes and ketones. In situ-generation of acetals and ketals, as well as removal afterwards, makes the C–H bond functionalization process more straightforward and efficient. This also represents the first example of chelation-directed meta-C–H functionalization of aromaticaldehydes and ketones.
