title: Synthesis and anxiolytic activity of a series of pyrazino[1,2-a][1,4]benzodiazepine derivatives.
abstract: The synthesis and biological evaluation of some derivatives of pyrazino[1,2-a][1,4]benzodiazepines for anxiolytic and antidepressant activity are presented. Significant levels of anxiolytic activity were noted for 7-(o-chlorophenyl)-9-chloro-1,2,3,4,4a,5-hexahydro-3-methylpyrazino[1,2-a];E11,4]benzodiazepine (4b).
