    摘要: Ligands for the gastrin and cholecystokinin (CCK) receptors are provided, together with methods for preparing such ligands, and compounds which are useful intermediates in such methods. Pharmaceutical compositions comprising such ligands, methods for preparing such pharmaceutical compositions, and methods of treatment using these compositions also are provided. The ligands have the formula (I): where n is from 1 to 3; X and Y are independently ═N— or —N(R5)— where R5 is selected from the group consisting of H, Me, Et, Pr, Bn, —OH and —CH2COOR6, where R6 represents H, Me, Et, Pr or Bn; R1 is H or a C1-C15 saturated carbocylic ring optionally substituted with OMe, NMe2, CF3, Me, F, Cl, Br or I where up to three H atoms may optionally be replaced by halogen atoms; R2 is selected from H, Me, Et, Pr and OH, each R2 being independently selected from H, Me, Et, Pr and OH when n is greater than 1; R3 is selected from the group consisting of H, Me, Et and Pr when n is 1; or, when n is greater than 1, each R3 is independently selected from the group consisting of H, Me, Et and Pr, or two R3 groups on neighbouring carbon atoms are linked to form a C3 to C6 carbocylic ring, or two R3 groups are absent from neighbouring carbon atoms which are linked by a double bond; or R2 and R3 on the same carbon atom together represent an ═O group; R4 is H or a C3 to C10 alicyclic ring where up to three H atoms may optionally be replaced by halogen atoms; Z is selected from the group consisting of: Q is a 6-membered aromatic carbocycle substituted with 1 or 2 V groups and optionally substituted with 1, 2 or 3 T groups; V is selected from the group consisting of —CO—NH—SO2—Ph, —SO2—NH—CO—Ph, —CH2OH, or a group of the formula —R7U, where U is selected from the group consisting of —COOH, tetrazolyl, —CONHOH and —SO3H; and R7 is selected from the group consisting of a bond; C1 to C6 hydrocarbylene, optionally substituted by hydroxy, amino or acetamido; —O—(C1 to C3 alkylene)-; —SO2NR8—CHR9—; —CO—NR8—CHR9—, where R8 and R9 are independently selected from H and methyl; and —NH—(CO)c—CH2—, where c is 0 or 1.
