摘要:
The present invention relates to hexahydroazepine derivatives of formula ##STR1## in which: A=--CO--CH.sub.2 --, --CH(OH)--CH.sub.2 --; --CH.sub.2 --CH.sub.2 --; --CH.dbd.CH--; --C.tbd.C--;X=H or a halogen;Y=cyclohexyl or, when X is H, phenyl.It likewise relates to the salts of the said derivatives, to a process for the preparation of these and to the pharmaceutical compositions containing them, more particularly as antipsychotic agents.
摘要:
The invention concerns the use of a compound of formula (I) ##STR1## wherein R and R.sub.1, each independently, represent a hydrogen atom or a methyl group, and its pharmaceutically acceptable acid addition salts, as free radical scavengers. The pharmaceutical compositions containing these compounds may be employed in the treatment and/or prevention of pathological processes involving cell damage due to the formation of free radicals.The invention also concerns the compounds of formula (I) wherein at least one of R and R.sub.1 is methyl, which are new compounds, as well as the process for the preparation thereof and the pharmaceutical compositions containing them.
