    • A benzodiazepine derivative represented by general formula (I) and a pharmaceutically acceptable salt thereof, wherein R1 represents a single bond, -CH2-, -CH2O-, -OCH2-, -SCH2- or (a); R2 represents lower alkyl, -COOR5, -CONH(CH2)nCOOR5, -CONHSO2R5, -SO2NHCOR5 or optionally substituted heterocyclic group, (wherein R5 represents hydrogen, lower alkyl or benzyl; and n represents an integer of 1 to 5); R3 represents a single bond, -CO- or -CONH; and R4 represents optionally substituted heterocylic group, optionally substituted lower alkyl, optionally substituted lower cycloalkyl, optionally substituted aryl, or lower alkoxycarbonyl. This compound has a high affinity for gastrin receptors and/or CCK-B receptors but not for CCK-A receptors, so that it is useful for curing diseases associated with gastrin receptors and/or CCK-B receptors without inducing the side effects associated with CCK-A receptors.
    • 由通式(I)表示的苯并二氮杂衍生物及其药学上可接受的盐,其中R 1表示单键,-CH 2 - , - CH 2 O - , - OCH 2 - , - CH 2 - 或(a)。 R 2表示低级烷基,-COOR 5,-CONH(CH 2)n COOR 5,-CONHSO 2 R 5,-SO 2 NHCOR 5或任选取代的杂环基(其中R 5表示氢,低级烷基或苄基; n表示1〜5的整数)。 R3表示单键,-CO-或-CONH; 并且R 4表示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。 该化合物对胃泌素受体和/或CCK-B受体具有高亲和力,但不对CCK-A受体具有高亲和力,因此它可用于治疗与胃泌素受体和/或CCK-B受体相关的疾病,而不诱导与 CCK-A受体。
