  Computer-Aided Molecular Modeling, Synthesis, and Biological Evaluation of 8-(Benzyloxy)-2-phenylpyrazolo[4,3-c]quinoline as a Novel Benzodiazepine Receptor Agonist Ligand

  摘要：

  Using computer-aided conformational analysis, based on molecular dynamics simulation, cluster analysis, and Monte Carlo techniques, we have designed and synthesized compounds in which a benzyloxy substituent has been incorporated into a series of pyrazoloquinoline benzodiazepine receptor (BZR) ligands, Earlier studies had shown that the benzyloxy group could act as part of the agonist pharmacophoric determinant in the beta-carboline ring system. Furthermore, the agonist beta-carboline had been correlated with a binding site orientation and volume fit for an agonist 6-phenylimidazobenzodiazepine carboxylate. The present study was undertaken to determine whether the benzyloxy substituent could be used as an agonist pharmacophoric descriptor for the phenylpyrazolo[4,3-c]quinolin-3-one BZR ligands, The results of a determination of GABA shift ratios for the synthetic ligands indicate that 8-(benzyloxy)-2-phenylpyrazolo[4,3-c]quinolin-3-one can be predicted to be an agonist at the BZR.

  A large series of 2-aryl(heteroaryl)-2,5-dihydropyrazolo[4,3-c]quinolin-3(3H)-ones (PQ, 106 compounds), carrying appropriate substituents at the quinoline and N-2-phenyl rings, were designed, prepared and tested as central benzodiazepine receptor ligands. Compounds with an affinity significantly higher than the parent compound CGS-8216 were obtained, the most active ligand showing a pIC(50) = 10.35. Hansch and comparative molecular field analyses gave coherent results suggesting the main structural requirements of high receptor binding affinity. The possible formation of a three-centred hydrogen bond (HB) at the HB donor site H-2, as a key interaction for high receptor binding affinity, was assessed by the calculation and comparison of the molecular electrostatic potentials of a series of selected ligands.
