Syntheses are reported for some 6-chloro(alkoxy, alkylthio and phenylthio)-3-benzamidomethyl-(acetamidomethyl and methoxy)-2-arylimidazopyridines and some corresponding imidazo-pyridazines, imidazopyrimidines and imidazopyrazines.IC50 values (or percentage displacement) are reported and discussed for the displacement of 3H>diazepam from rat brain membrane by each of these compounds.The imidazopyridines were generally less potent than the imidazopyridazines but considerably more potent than the corresponding imidazopyrimidines or imidazopyrazines.Substitution of 2-aryl group by a 2-alkyl group in imidazopyridazines led to a significant loss of activity.
