Substituted carbohydrazides 1a - e reacted with ethenetetracarbonitrile (2) in dimethylformamide with formation of diacylhydrazines 4a - e and 5-amino-1-substiuted pyrazole-3,3,4-tricarbonitriles 5a - e. On the other hand, 1a-c reacted with diethyl (E)-2,3-dicyanobutenedioate (3) to give oxadiazinone and pyrazolone derivatives 12a - e and 13a - e, respectively.

prepared compounds 4a–d, 5a–d and 11a–d were evaluated each for antidepressantactivity using tail suspension behavioral despair test and anticonvulsantactivity against PTZ induced seizures in mice. Compounds 4a and 4b induced markedly antidepressantactivity compared to imipramine, and their activities as antidepressant nearly equal twice the activity of imipramine at 10 mg kg−1 dose level.
