ABSTRACT:
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.
