The invention relates to novel nitrogen- and sulfur-containing heterocyclic compounds of the formula (I), acid addition salts thereof, pharmaceutical compositions containing them and a process for their preparation. In the formula (I) STR1 Ar stands for an optionally mono- or polysubstituted aryl or heteroaryl group; R1 means a carbonyl or (C2-6 alkenyl)carbonyl group; R2 stands for hydrogen C1-6 alkyl, phenyl or phenyl (C1-4 alkyl) group; R3 means hydrogen or (C1-6 alkoxy)carbonyl group; R4 and R5 stand, independently from each other, for hydrogen or C1-6 alkyl group; R6 ogen, C1-6 alkyl group or halophenyl group; m is 0 or 1; and n is 1 or 2, with the proviso that R2 means hydrogen when m is 0. The compounds of formula (I) show a significant cerebral antihypoxic action and thus, they can be used for the treatment of diseases caused by hypoxic brain damages such as e.g. the senile dementia, Alzheimer's disease or disturbances of the cognitive function.

The invention relates to nitrogen- and sulfur--containing heterocyclic compounds of the formula (I), wherein, Ar represents an optionally mono- or polysubstituted aryl or heteroaryl group;, R1 represents a carbonyl or (C2 6alkenyl)--carbonyl group;, R2 represents a hydrogen atom, or a C1 6alkyl, phenyl or phenyl(C1 4alkyl) group;, R3 represents a hydrogen atom or a (C1 6 alkoxy)carbonyl group;, R4 and R5, which may be the same or different, represent a hydrogen atom or a C1 6alkyl group;, R6 represents a hydrogen atom or a C1 6alkyl group or halophenyl group;, m is 0 or 1; and, n is 1 or 2,with the proviso that R2 is a hydrogen atom when m is 0, and acid addition salts of the compounds of formula (I) and pharmaceutical compositions thereof. The invention also relates to processes for the preparation of these compounds. The compounds of formula (I) show a significant cerebral antihypoxic activity.
