The present invention provides compounds of formula (I); wherein each of R1 to R4 is independently selected from hydrogen, a halogen, a substituted or unsubstituted cyclic and heterocyclic moiety, substituted or unsubstituted, linear or branched alkyl, alkyloxy, alkylcarbonyl, alkyloxycarbonyl, alkenyl, alkenyloxy, alkenylcarbonyl, alkenyloxycarbonyl, alkynyl, alkynyloxy, alkynylcarbonyl, alkynyloxycarbonyl, aryl, benzyl, arlyoxy, arylcarbonyl, aryloxycarbonyl and sulphur equivalents of said oxy, carbonyl and oxycarbonyl moieties, and A is NH, or (CH2)n, where n is preferably 0, 1 or 2. The invention also relates to methods for preparing the compounds and their uses as CCK receptor ligands and CCK antagonists.
本发明提供了化合物的结构公式(I);其中R1至R4中的每一个均独立地选自氢、卤素、取代或未取代的环状和杂环状基团、取代或未取代的直链或支链烷基、烷氧基、烷基羰基、烷氧羰基、烯基、烯氧基、烯基羰基、烯氧羰基、炔基、炔氧基、炔基羰基、炔氧羰基、芳基、苄基、芳氧基、芳基羰基、芳氧羰基以及上述氧、羰基和氧羰基基团的硫等效物,A为NH,或(CH2)n,其中n优选为0、1或2。该发明还涉及制备这些化合物的方法以及它们作为CCK受体配体和CCK拮抗剂的用途。
