Abstract
Compounds of formula: ##STR1## in which V and W are H, halogen, alkyl (1-4C) or alkoxy (1-4C), amino, or acylamino, Z is phenyl, optionally substituted, thienyl, or pyridyl, R.sub.1 is alkyl (1-6C), alkoxyalkyl, cycloalkyl (3-6C), phenyl, phenylalkyl, or cycloalkylalkyl, R.sub.2 is alkyl (1-6C), alkoxyalkyl, cycloalkyl (3-6C), phenyl, phenylalkyl, cycloalkylalkyl, or morpholino, and NR.sub.1 R.sub.2 can also be pyrrolidino, optionally substituted piperidino, optionally substituted morpholino, thiomorpholino, optionally substituted piperazino, or an optionally substituted piperazinone, are useful as anxiolytic agents.
Claims9
A racemic or steroisomeric compound of formula ##STR9## in which V and W, which may be identical or different, denote hydrogen, halogen, alkyl of 1 to 4 carbon atoms, alkoxy of 1 to 4 carbon atoms, amino, or acylamino of 1 to 4 carbon atoms,
- Z denotes phenyl, thienyl, pyridyl, or phenyl substituted by one or two substituents selected from halogen, alkyl of 1 to 4 carbon atoms, alkoxy of 1 to 4 carbon atoms, trifluoromethyl, nitro, and amino, but not including more than one nitro,
- R.sub.1 denotes a linear or branched alkyl of 1 to 6 carbon atoms, alkoxyalkyl in which the alkyl and alkoxy portions each have 1 to 4 carbon atoms, cycloalkyl of 3 to 6 carbon atoms, phenyl, phenylalkyl in which the alkyl portion has 1 to 4 carbon atoms, or cycloalkylalkyl in which the alkyl has 1 to 3 carbon atoms and the cycloalkyl portion has 3 to 6 carbon atoms,
- R.sub.2 denotes a linear or branched alkyl of 1 to 6 carbon atoms, alkoxyalkyl in which the alkoxy and alkyl have 1 to 4 carbon atoms each, cycloalkyl of 3 to 6 carbon atoms, phenyl, phenylalkyl in which the alkyl portion has 1 to 4 carbon atoms, or cycloalkylalkyl in which the alkyl has 1 to 3 carbon atoms and the cycloalkyl has 3 to 6 carbon atoms, or a 4-morpholine ring, and R.sub.1 and R.sub.2 can also form, together with the nitrogen atom to which they are attached:
- pyrrolidino;
- piperidino unsubstituted or substituted by hydroxy, alkyl of 1 to 4 carbon atoms, alkoxy of 1 to 4 carbon atoms, or alkyloxycarbonyl in which the alkyl portion has 1 to 4 carbon atoms;
- morpholino unsubstituted or substituted by one or two alkyls of 1 to 4 carbon atoms;
- thiomorpholino;
- piperazino unsubstituted or substituted on the nitrogen atom by alkyl of 1 to 4 carbon atoms, alkyloxycarbonyl in which the alkyl portion has 1 to 4 carbon atoms, acyl of 2 to 5 carbon atoms, or formyl;
- or a piperazinone ring unsubstituted or substituted on the nitrogen atom by alkyl of 1 to 4 carbon atoms, and also, where it can exist, a salt of such a compound with a pharmaceutically acceptable acid.
A pharmaceutical composition useful as an anxiolytic containing, in association with one or more diluents or adjuvants which are compatible and pharmaceutically acceptable, at least one racemic or stereoisomeric compound of formula:
- ##STR10## in which V and W, which may be identical or different, denote hydrogen, halogen, alkyl of 1 to 4 carbon atoms, alkoxy of 1 to 4 carbon atoms, amino, or acylamino of 1 to 4 carbon atoms,
- Z denotes phenyl, thienyl, pyridyl, or phenyl substituted by one or two substituents selected from halogen, alkyl of 1 to 4 carbon atoms, alkoxy of 1 to 4 carbon atoms, trifluoromethyl, nitro, and amino, but not including more than one nitro,
- R.sub.1 denotes a linear or branched alkyl of 1 to 6 carbon atoms, alkoxyalkyl in which the alkyl and alkoxy portions each have 1 to 4 carbon atoms, cycloalkyl of 3 to 6 carbon atoms, phenyl, phenylalkyl in which the alkyl portion has 1 to 4 carbon atoms, or cycloalkylalkyl in which the alkyl portion has 1 to 3 carbon atoms and the cycloalkyl portion has 3 to 6 carbon atoms, R.sub.2 denotes a linear or branched alkyl of 1 to 6 carbon atoms, alkoxyalkyl in which the alkoxy and alkyl have 1 to 4 carbon atoms each, cycloalkyl of 3 to 6 carbon atoms, phenyl, phenylalkyl in which the alkyl portion has 1 to 4 carbon atoms, or cycloalkylalkyl in which the alkyl has 1 to 3 carbon atoms and the cycloalkyl has 3 to 6 carbon atoms, or a 4-morpholine ring, and R.sub.1 and R.sub.2 can also form, together with the nitrogen atom to which they are attached:
- pyrrolidino;
- piperidino unsubstituted or substituted by hydroxy, alkyl of 1 to 4 carbon atoms, alkoxy of 1 to 4 carbon atoms, or alkyloxycarbonyl in which the alkyl portion has 1 to 4 carbon atoms;
- morpholino unsubstituted or substituted by one or two alkyls of 1 to 4 carbon atoms;
- thiomorpholino;
- piperazino unsubstituted or substituted on the nitrogen atom by alkyl of 1 to 4 carbon atoms, alkyloxycarbonyl in which the alkyl portion has 1 to 4 carbon atoms, acyl of 2 to 5 carbon atoms, or formyl;
- or a piperazinone ring unsubstituted or substituted on the nitrogen atom by alkyl of 1 to 4 carbon atoms, or, where it exists, a salt of such a compound with a pharmaceutically acceptable acid.
