  2-(Oxadiazolyl)- and 2-(thiazolyl)imidazo[1,2-a]pyrimidines as agonists and inverse agonists at benzodiazepine receptors

  摘要：

  Oxadiazoles, like the benzoyl group in a series of imidazo[1,2-alpha]pyrimidines, have been found to be metabolically stable alternatives to ester groups in benzodiazepine-receptor ligands. This change has lead to a number of compounds which bind to the receptors and which exhibit potent agonist activity in a food-motivated conflict test thought to predict anxiolytic properties. Compounds 4, 5, and 13 were equipotent with chlordiazepoxide but showed little or no myorelaxant effects. Replacing the oxadiazole group by thiazole gave compounds such as 23 which binds to the benzodiazepine receptor but exhibits the intrinsic activity of a partial inverse agonist in vivo.

  Several series of heterocyclic carboxylic esters were found to be active in the benzodiazepine receptor binding assay, a typical example being ethyl 7-ethyl-5-methoxyimidazo[1,2-a]quinoline-2-carboxylate (4b) with an IC50 of 150 nM. The corresponding phenylmethanone 5d was more potent with an IC50 of 14 nM and was orally active in animal models thought to predict anxiolytic effects. The synthesis of a large number of compounds resulted in the optimization of this activity in a series of (imidazo[1,2-a]pyrimidin-2-yl)phenylmethanones of which compounds 7e, 8b, 8h, 8j, and 8k were equipotent with chlordiazepoxide while exhibiting reduced anticonvulsant activity, little or no muscle relaxation, and negligible sedative effects.
