  • Title: [Pharmacophore model of integrin alphavbeta3 antagonists].
    Author: Cheng GY, Ni GH, Jiang FC.
    Journal: Yao Xue Xue Bao; 2009 Apr; 44(4):379-85. PubMed ID: 19545055.
    Abstract:
    In order to generate a pharmacophore model of integrin alphavbeta3 receptor antagonists and design lead compounds which have potent and selective activity against alphavbeta3 receptor with the help of this model. Thirty compounds (four categories) with highly inhibitory activity against the integrin alphavbeta3 receptor (IC50 < 110 nmol x L(-1)), amide, piperazine, piperidine, gamma-valerolactam as the intermediate junction, separately, were selected as a training set to construct a three-dimensional pharmacophore models of integrin alphavbeta3 receptor antagonists with the Catalyst software. The best pharmacophore model of integrin alphavbeta3 receptor antagonists with RMS = 0.73, Correl = 0.90, Weight = 1.17, Config = 14.00 is found out, which consisting of four features: a neg ionizable core (NI), two aliphatic hydrophobic core (HP) and an aromatic ring center (RA). Some new and easily obtained compounds with fine ADME properties and highly potent activity against alphavbeta3 receptor were designed with the new pharmacophore models.
