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.
环酰胺衍生物的定义式(I)或其盐:R1--(CH2)n-z,其中R1是来自环酰胺化合物的取代或未取代的基团,n为0或1到10的整数,Z为##STR1##,其中R2为芳基,取代芳基,环烷基或杂环基,m为1到6的整数,R3为氢或低级烷基,R4为芳基或取代芳基,环烷基或杂环基,p为1到6的整数,只要环酰胺化合物是喹唑啉酮或喹唑啉二酮,R2和R4均不是芳基或取代芳基。该环酰胺化合物具有药理学效应,可预防和治疗由中枢胆碱功能不足引起的疾病。
