title: Researches on psychotropic agents. IV. Synthesis and neuropsychopharmacological effects of 1,3,4,14 b-tetrahydro-10-methyl-2H,10H- pyrazino[2,1-d] pyrrolo[1,2-b][1,2,5]benzotriazepine and its derivatives.
abstract: The synthesis and neuropsychopharmacological properties of new 1,3,4,14b-tetrahydro-2H,10H-pyrazino [2,1-d] pyrrolo [1,2-b] [1,2,5] benzotriazepine derivatives related to antidepressant agent aptazepine are reported. The new derivatives displayed sedative-miorelaxant activity in mice, but no significant antagonist effect on clonidine blockade of phenylquinone-induced abdominal constriction. Among test compounds 4a, 4l and 4n showed high antinociceptive effect on the hot-plate test and compound 4e protected from death and convulsion all the electroshocked animals.
