ABSTRACT:
An aminopyridine compound represented by the formula: ##STR1## wherein n represents 0 or 1; Z represents .dbd.S, .dbd.O, .dbd.NCN or .dbd.CHNO.sub.2 ; R.sub.1 represents --CN, --NR.sub.3 R.sub.4, --CONR.sub.3 R.sub.4, --NHNR.sub.3 R.sub.4, --NHCONHR.sub.3, --NHSO.sub.2 R.sub.3 or --SR.sub.3 ; R.sub.2 represents H, or substituted or unsubstituted alkyl; R.sub.3 and R.sub.4, which may be the same or different, represent H, substituted or unsubstituted alkyl, aryl, substituted or unsubstituted acyl or alkoxycarbonyl group; and R.sub.3 and R.sub.4 may form a heterocyclic ring together with a nitrogen atom to which R.sub.3 and R.sub.4 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.
