    摘要： A benzodiazepine derivative of formula I, or a pharmaceutically acceptable salt thereof:
    wherein

    (a) R 1 is -CH 2 CHOH(CH 2 ) a R 4 or a ketone group -CH 2 CO(CH 2 ) a R 5 in which a is 0 or 1 and R 4 and R 5 are selected from alkyl groups of up to 8 carbon atoms;
    (b) R 2 and R 3 are independently selected from optionally substituted monocyclic aromatic carbocylic and heterocyclic residues of 5 or 6 ring atoms of which one, two or three may be heteroatoms, the optional substituents being selected from halogen atoms and hydroxy, amino, nitro, carboxylic acid, carboxamido and cyano groups and alkyl, alkoxy, alkylamino and dialkylamino groups in which the or each alkyl group is of up to 8 carbon atoms; and
    (c) W and X are selected independently from halogen and hydrogen atoms and C 1 -C 8 alkyl and C 1 -C 8 alkoxy groups.

    These compounds are gastrin and/or CCK-B receptor antagonists.
