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 ##STR1## 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.

Cyclic amide derivatives

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.

Bicyclic amide derivatives, compositions and methods of treatment

The cyclic amide derivative is defined by the formula (I) or a salt thereof: R.sup.1 --(CH2)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, 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.

Benzoxazine derivatives

The cyclic amide derivative is defined by the formula (I) or a salt thereof:

1,2,3,4 tetrahydropteridinone cyclic amide derivatives

2H-3,4-tetrahydroquinazoline-2-one and

An oxazolidone derivative represented by formula (I) which has a monoamine oxidase inhibition effect: ##STR1## {wherein A and B each represents a nitrogen atom, a sulfur atom or an oxygen atom, with the proviso than at least one of A and B must be a nitrogen atom, R.sup.1 represents a group of the formula: ##STR2## (in which n and m each represents 0 or an integer of 1 to 4, and R.sup.3 and R.sup.4 each represents a hydrogen atom, a hydroxyl group, a lower alkyl group, etc. ), a group represented by the formula: ##STR3## (in which p and q each represents 0 or an integer of 1 to 4 and X represents an oxygen atom, sulfur atom, etc.) and a group represented by the formula: ##STR4## R.sup.2 represents a hydrogen atom or a lower alkyl group}.

Oxazolidone derivative

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 ##STR1## 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.

A cyclic amine compound is defined by the formula: ##STR1## in which J is indanyl, indanonyl, indenyl, indenonyl, indanedionyl, tetralonyl, benzosuberonyl, indanolyl or a divalent group thereof, K is phenyl, an arylalkyl or cynnamyl, B is --(CHR22) r--, R22 being H or methyl, --CO-- (CHR22)r--, .dbd.(CH--CH.dbd.CH)b--, .dbd.CH--(CH2)c-- or .dbd.(CH--CH)d.dbd. and the ring including T and Q is piperidine. The compound is useful to treat senile dementia.
