The present invention relates to a group of novel benzisoxazole derivatives which are potent and selective antagonists of the dopamine D4-receptor. The compounds have general formula (I) wherein (R1)n represents 0, 1, or 2 substituents, which can be the same or different, from the group C1-3-alkyl or alkoxy, halogen, trifluoromethyl, nitro, amino mono- or dialkyl (C1-2)-amino, sulfonyl-(C1-3)alkyl or -alkoxy, sulfonyl trifluoromethyl, sulfonyl amino, and sulfonyl mono- or dialkyl (C1-2)-amino, X is O, S, NH or NCH3, Y represents CH2, or (CH2)2, (R2)m represents 0, 1, or 2 substituents, which can be the same or different, from the group methyl and ethyl, or (R2)m is a methylene bridge or ethylene bridge, A is a group —CH2—(CRH)p— wherein R is hydrogen or methyl and p is 0 or 1, and B represents 2- or 3-indolyl or 2-benzimidazolyl, which groups may be substituted at carbon with 1 or 2 substituents from the group C-1-3-alkyl or alkoxy, halogen, trifluoromethyl, nitro, amino, mono- or dialkyl (C1-2)amino, sulfonyl-(C1-3)alkyl or -alkoxy, sulfonyl trifluoromethyl, sulfonyl amino, and sulfonyl mono- or dialkyl (C1-2)-amino.
本发明涉及一组新型苯并异噁唑衍生物,它们是多巴胺D4受体的有效和选择性拮抗剂。这些化合物的一般式为(I),其中(R1)n代表0、1或2个取代基,可以是来自C1-3烷基或烷氧基、卤素、三氟甲基、硝基、氨基单或二烷基(C1-2)-氨基、磺酰基-(C1-3)烷基或-烷氧基、磺酰基三氟甲基、磺酰基氨基和磺酰基单或二烷基(C1-2)-氨基的相同或不同的基团;X代表O、S、NH或NCH3;Y代表CH2或(CH2)2;(R2)m代表0、1或2个取代基,可以是甲基和乙基,或(R2)m是亚甲基桥或乙烯桥;A是一个基团-CH2-(CRH)p-,其中R是氢或甲基,p为0或1;B代表2-或3-吲哚基或2-苯并咪唑基,这些基团可以在碳上用来自C-1-3烷基或烷氧基、卤素、三氟甲基、硝基、氨基、单或二烷基(C1-2)-氨基、磺酰基-(C1-3)烷基或-烷氧基、磺酰基三氟甲基、磺酰基氨基和磺酰基单或二烷基(C1-2)-氨基的1或2个取代基。
