Thirteen (13) compounds of N-phenyl-O-alkyl carbamates (1 and 3), N,N-diethyl-N'-alkyl/aryl/phenylpiperazinoureas (4-6, 8-12), N-phenyl-N'-phenylpiperazino/imidazoureas (2, 7), and N-ethyl-(N'-phenylpiperazino) thioureas 13 were synthesized and tested for their antidepressant-like activity in mice. It was found that compound N-phenyl-O-heptyl carbamate 1 and N-phenyl-N'-phenylpiperazinourea 2 showed 32.5 and 27.7% antidepressant activity in the forced swim test in mice, respectively. Considering other carbamates it was found that a decrease in alkyl chain length caused a marked decline in the antidepressant activity. Compounds 1-4 show even higher activities in the forced swim test than the standard phenelzine.

The present invention relates to a novel piperazine compound represented by the following general formula (I): ##STR1## wherein X stands for a hydrogen or halogen atom, an alkoxy, carboxy or alkoxycarbonyl group or a group R.sup.3 CO-- in which R.sup.3 stands for an alkyl group having 1 to 4 carbon atoms, R.sup.1 stands for a hydrogen atom or an alkyl group, and R.sup.2 stands for a hydrogen atom or an alkyl group. These compounds are valuable as immunopotentiators, such as for the treatment of chronic rheumatoid arthritis and other diseases accompanied by reduction or abnormal change of the immune function.
