An aminopyridine compound represented by the formula:
wherein n represents 0 or 1; Z represents =S, =O, =NCN or =CHNO₂; R₁ represents -CN, -NR₃R₄, -CONR₃R₄, -NHNR₃R₄, -NHCONHR₃, -NHSO₂R₃ or -SR₃; R₂ represents H, or substituted or unsubstituted alkyl; R₃ and R₄, which may be the same or different, represent H, substituted or unsubstituted alkyl, aryl, substituted or unsubstituted acyl or alkoxycarbonyl group; and R₃ and R₄ may form a heterocyclic ring together with a nitrogen atom to which R₃ and R₄ are bound, through another heteroatom or without it; or an acid salt thereof, which is excellent in pharmacological effect and repressed in side effects as a drug for circulatory diseases.
