Abstract

Oximes of the formula: ##SPC1## And their acid salts, wherein A is a branched or unbranched, saturated or unsaturated alkylene chain of 0-6 carbon atoms, B is a basic nitrogen-containing group such as an amino, alkylamino, dialkylamino, cycloalkylamino, dicycloalkylamino, cycloalkylalkylamino, dicycloalkylalkylamino, alkylarylamino, alkylaralkylamino, a piperidino, pyrrolidino, hexamethyleneimino, morpholino, thiomorpholino, N-alkylpiperazino or N-(2-hydroxyalkyl)-piperazino group, n is 1 or 2 and X is --CH.sub.2 --, --(CH.sub.2).sub.3 -- or --CH = CH--, and R.sub.1 and R.sub. 2 are each hydrogen, halogen, alkyl of 1-4 carbon atoms, alkoxy, alkylmercapto groups of 1-4 carbon atoms, hydroxyl, nitro, amino or trifluoromethyl, are useful for their anti-depressant activity. Pharmaceutical compositions may be prepared which comprise an anti-depressant amount of at least one such compound in combination with a pharmaceutically acceptable inert diluent or carrier. Depression in humans and animals may be treated by administering an anti-depressant amount of such an oxime to such human or animal.
