The compounds of formula (I) were studied on laboratory animals and showed activites in the psychotropic field, as potential anti-depressants.

These activities were revealed in the following tests:

Test A: Potentiation in mice of generalized trembling caused by an interperitoneal injection (200 mg/kg) of dl-5-hydroxytryptophane, following the protocol described by C. GOURET and G. RAYNAUD in J. Pharmacol. (Paris), (1974), 5, 231.

Test B: Antagonism with respect to the ptosis observed one hour after an intravenous injection (2 mg/kg) of reserpine given to mice, following the protocol described by C. GOURET and J. THOMAS in J. Pharmacol. (Paris), 1973, 4, 401.

The results of these two tests, as well as those of a well-know reference substance, TOLOXATONE, are collected in table IV below:

As can be seen from the results shown in table IV, the compounds of formula (I) have an activity greater than that of the reference compound.

They are indicated in endogenous and exogenous depressive conditions and will be administered orally in the form of tablets, pills or capsules, at a dosage of 50 to 500 mg/day on average, of active substance.

They will also be administered in the form of an injectable solution at the rate of 5-50 mg/day of active substance, the solvent used being formed by binary or ternary mixtures containing for example water, polypropyleneglycol or polyethyleneglycol (quality: 300-400), or any other physiologically acceptable solvent, the relative proportions of the different solvents being adjusted with respect to the dose administered.
