(3-tert-Butyl-7-(5-methylisoxazol-3-yl)-2-(1-methyl-1-H-1,2,4-triazol-5-ylmethoxy)pyrazolo[1,5-d] [1,2,4]triazine (13) has been identified as a functionally selective, inverse agonist at the benzodiazepine site of GABA(A) alpha5 receptors. 13 is orally bioavailable, readily penetrates the CNS, and enhances performance in animal models of cognition. It does not exhibit the convulsant, proconvulsant, or anxiogenic activity associated with nonselective GABAA inverse agonists.
(3-叔丁基-7-(5-甲基异噁唑-3-基)-2-(1-甲基-1H-1,2,4-三唑-5-基甲氧基)吡咯并[1,5-d][1,2,4]三嗪(13)已被鉴定为苯二氮䓬位点GABA(A) alpha5受体上的功能选择性反激动剂。13具有口服生物利用度,能够轻易穿透中枢神经系统,并在认知动物模型中提高性能。与非选择性GABAA反激动剂不同,13不表现出致惊厥、促惊厥或焦虑性活性。
