wherein R1 is a bond, -CH2-, -CH2O-, -OCH2-, -SCH2- or a group of the formula:
R2 is a lower alkyl, -COOR5, -CONH(CH2)nCOOR5, -CONHSO2R5, -SO2NHCOR5, or an optionally substituted heterocyclic group (R5 is a hydrogen atom, lower alkyl or benzyl and n is an integer of 1 to 5); R3 is a bond, -CO- or -CONH-; and R4 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.

其中 R1 是键、-CH2-、-CH2O-、-OCH2-、-SCH2- 或式中的基团:
R2 是低级烷基、-COOR5、-CONH(CH2)nCOOR5、-CONHSO2R5、-SO2NHCOR5 或任选取代的杂环基团(R5 是氢原子、低级烷基或苄基,n 是 1 至 5 的整数);R3 是键、-CO- 或 -CONH-;和 R4 是任选取代的杂环基团、任选取代的低级烷基、任选取代的低级环烷基、任选取代的芳基或低级烷氧基羰基,或其药学上可接受的盐,对胃泌素受体和/或 CCK-B 受体具有高亲和力,但对 CCK-A 受体没有亲和力,可用于治疗与胃泌素受体和/或 CCK-B 受体相关的疾病,而不会诱发与 CCK-A 受体相关的副作用。
