  名称：

  2-Phenyl-3H-imidazo[4,5-b]pyridine-3-acetamides as nonbenzodiazepine anticonvulsants and anxiolytics

  摘要：

  A series of 2-phenyl-3H-imidazo[4,5-b]pyridine-3-acetamides were designed and synthesized as non-benzodiazepine anxiolytics based on a molecular disconnection of a typical 1,4-benzodiazepine (BZD). A number of these compounds showed submicromolar potency in a [H-3]benzodiazepine binding assay in vitro and good potency in protecting rodents against pentylenetetrazole-induced seizures. Compound 84 appears to be a selective anticonvulsant (pentylenetetrazole) agent when tested against a profile of chemically and electrically induced seizures in mice. In addition, compound 148 appears to be a selective anxiolytic/hypnotic agent on the basis of biochemical and pharmacological characterization. It appears to be a full BZD agonist as assessed by GABA shift ratio and to be effective in punishment and nonpunishment animal models of anxiety. In addition, it shows a lower side-effect profile than diazepam as assessed by rotorod neurotoxicity and potentiation of ethanol-induced sleep time in mice. The chemistry and structure-activity relationships of this series is discussed.

  Imidazoheterocyclic compounds having the formula: wherein A is a pyridine ring in any of its four positions; B is carbonyl, thioxomethyl or hydroxymethylene; Z is hydrogen, halogen, loweralkyl, hydroxy, loweralkoxy, diloweralkylamino or nitro; Ar is phenyl, pyrido, thienyl or furanyl; and W forms a wide combination of groups with B, including acids, esters, alcohols, amides and ketones. The compounds have CNS activity and find use as muscle relaxants, anticonvulsants and antianxiety agents.
