A benzodiazepine derivative of the formula (I): ##STR1## wherein R.sub.1 is a bond, --CH.sub.2 --, --CH.sub.2 O--, --SCH.sub.2 -- or a group of the formula: ##STR2## R.sub.2 is a lower alkyl, --COOR.sub.5, --CONH(CH.sub.2).sub.n COOR.sub.5, --CONHSO.sub.2 R.sub.5, --SO.sub.2 NHCOR.sub.5, or an optionally substituted heterocyclic group (R.sub.5 is a hydrogen atom, lower alkyl or benzyl and n is an integer of 1 to 5); R.sub.3 is a bond, --CO-- or --CONH--; and R.sub.4 is an optionally substituted heterocyclic group, optionally substituted lower alkyl, optionally substituted lower cycloalkyl, optionally substituted aryl, or lower alkoxycarbonyl group, or a pharmaceutically acceptable salt thereof, which has a high affinity for gastrin receptors and/or CCK-B receptors but not for CCK-A receptors, and is useful for treating diseases associated with gastrin receptors and/or CCK-B receptors without inducing the side effects associated with CCK-A receptors.
一种苯二氮平衍生物,其化学式为(I):##STR1## 其中R.sub.1是一个键,--CH.sub.2 --,--CH.sub.2 O--,--SCH.sub.2 --或式子的基团:##STR2## R.sub.2是较低的烷基,--COOR.sub.5,--CONH(CH.sub.2).sub.n COOR.sub.5,--CONHSO.sub.2 R.sub.5,--SO.sub.2 NHCOR.sub.5,或者是一个可选取代的杂环基团(其中R.sub.5是氢原子,较低的烷基或苄基,n是1到5的整数);R.sub.3是一个键,--CO--或--CONH--;R.sub.4是一个可选取代的杂环基团,可选取代的较低烷基,可选取代的较低环烷基,可选取代的芳基,或较低的烷氧羰基基团,或其药学上可接受的盐,其具有高亲和力对于胃泌素受体和/或CCK-B受体,但不具有对CCK-A受体的副作用,可用于治疗与胃泌素受体和/或CCK-B受体相关的疾病,而不会引起与CCK-A受体相关的副作用。
