Phenyl-3-aminoalkyl-4-methyl-2,6-dioxopiperidines of the Formula I
wherein:
R1 represents methoxy, ethoxy or hydroxy,
R2 represents methoxy, ethoxy. hydroxy or hydrogen;
each R3 independently represents methyl or ethyl;
R4 represents hydrogen or methyl;
R5 represents hydrogen or methyl; and
n represents 2 or 3,
and a pharmacologically acceptable acid addition salt thereof (a) have anxiolytic activity, (b) antagonize the anxiogenic activity of benzodiazepine inverse agonists. (c) reducechronic abnormally high brain levels of serotonin or its metabolite 5-hydroxy-indoleacetic acid and (d) have antibacterial and antiviral activity. These activities are believed to be related to a reduction in serotonin turnover caused by blocking the depolarisation activation of tryptophan hydroxylase. Novel compositions comprise the compounds with a benzodiazepine agonist or benzodiazepine inverse agonist.
