The cyclic amide derivative is defined by the formula (I) or a
salt thereof: R1-(CH2)n-Z
in which R1 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
R2 being an aryl, a substituted aryl, a cycloalkyl or a heterocyclic group, m being an integer of 1 to 6, R3 being hydrogen or a lower alkyl, R4 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, R2 and R4 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.
