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.
