摘要:
A new series of phenylpiperazine-based derivatives with strong antagonistic activity for alpha(v)beta(3) integrin was synthesized. Of these derivatives, the fluorine-substituted compound 8 showed strong inhibitory activity and high selectivity for alpha(v)beta(3) integrin receptor (IC50 = 0.055 nM). In vivo evaluation of the antistenotic effects of 8 indicated that this compound significantly inhibits neointima formation in rat balloon injury model. (C) 2004 Elsevier Ltd. All rights reserved.
