ABSTRACT:
The cyclic amide derivative is defined by the formula (I) or a salt thereof: R.sup.1 --(CH.sub.2)n-Z in which R.sup.1 is a group derived from a cyclic amide compound, substituted or unsubstituted, n is zero or an integer of 1 to 10 and Z is ##STR1## R.sup.2 being an aryl, a substituted aryl, a cycloalkyl or a heterocyclic group, m being an integer of 1 to 6, R.sup.3 being hydrogen or a lower alkyl, R.sup.4 being an aryl or a substituted aryl, a cycloalkyl or a heterocyclic group, p being an integer of 1 to 6, provided that the cyclic amide compound is quinazoline-on or quinazoline-dion, R.sup.2 and R.sup.4 are neither aryl nor substituted aryl. The cyclic amide compound is pharmacologically effective to prevent and treat diseases due to insufficiency of the central choline functions.
