  Syntheses, pharmacological evaluation and molecular modelling of substituted 6-alkoxyimidazo[1,2-b]pyridazines as new ligands for the benzodiazepine receptor

  摘要：

  A series of 2,3-disubstituted-6-alkoxyimidazo[1,2-b] has been synthesized and evaluated for in vitro affinity for the benzodiazepine receptor (BZR). 3-(Benzamidomethyl or substituted benzamidomethyl)-6-methoxy-2-(3,4-methylenedioxyphenyl)imidazo[1,2-b]pyridazines were found to be the most potent BZR ligands (eg, 4a, IC50 7 nM; 4e, IC50 14 nM; 4v, IC50 8 nM). Imidazo[1,2-b]pyridazines unsubstituted in the 3-position, or containing builder alkoxy groups in the 6-position, were found to bind less strongly to the BZR. Selected compounds from the series were identified from in vitro GABA-shift experiments as BZR agonists. Molecular modelling has been employed to identify the common pharmacophoric points of lipophilic and hydrogen bonding, ligand-receptor interaction and areas of steric hindrance for these substituted imidazo[1,2-b]pyridazines at the BZR.
