Abstract: | The facile synthesis of 1,2,3]triazolo((4,5-d]2]benzazepines and dibenzoc,f]1,2,3]triazolo3,4-a]azepines by the addition of sodium azide to acetylenic benzophenones is described. Examination of the pharmacological data indicates that selected triazolobenzazepines are as potent as diazepam in the anti-pentylenetetrazole test and are weaker in the inclined screen and rotarod tests, suggesting that these compounds have antianxiety properties similar to diazepam with fewer deficits in motor coordination. In addition, a possible diazepam antagonist was found in the triazolo-benzazepine series. The dibenzotriazoloazepines were found to be inactive in four standard CNS screening procedures. |
