Since the compound of the present invention represented by the following formula (I) can strongly inhibit bonding of [3H]-serotonin and [3H]-5-CT to human serotonin 5-HT7 receptor subtype expressed in cultured cell line, the compound of formula (I) and pharmaceutically acceptable salts thereof can provide pharmaceutical conpositions for use in the treatment or prevention of mental diseases.
[In the above formula, A is N, CH, C having a double bond or CR5; each of B and Z is independently N, CH or CR1, with the proviso that A is N when B and/or Z is N; R1 is a hydrogen atom, a halogen atom, a lower alkyl group, a cyano group, a trihalomethyl group, a hydroxy group, an alkoxy group, an alkylthio group, an alkylsulfinyl group, an alkylsulfonyl group, an alkoxycarbonyl group, a sulfamoyl group, an amino group, a substituted amino group, a carbamoyl group, an alkylcarbamoyl group, an acyl group or a carboxy group; R2 is a hydrogen atom or a lower alkyl group; R3 is a hydrogen atom, a lower alkyl group or an aralkyl group; R4 is a hydrogen atom, a halogen atom, a lower alkyl group, a hydroxy group, an alkoxy group, an acyl group, an alkoxycarbonyl group, a nitro group, an amino group, a substituted amino gropup, a carbamoyl group, an alkylcarbamoyl group or an acyloxy group; R5 is a lower alkyl group, a cyano group, a carbamoyl group, a carboxy group, an acyl group, an acyloxy group, an alkoxy group, an alkoxycarbonyl group, a trihalomethyl group or a hydroxy group; and n is an integer of 2 to 6.]
由于下式(I)表示的本发明化合物能强烈抑制[3H]-serotonin和[3H]-5-CT与培养细胞系中表达的人5-羟色胺5-HT7受体亚型的结合,因此式(I)化合物及其药学上可接受的盐可提供用于治疗或预防精神疾病的药物组合。
[在上式中,A 是 N、CH、具有双键的 C 或 CR5;B 和 Z 各自独立地是 N、CH 或 CR1,但当 B 和/或 Z 是 N 时,A 是 N;R1 是氢原子、卤素原子、低级烷基、氰基、三卤甲基、羟基、烷氧基、烷硫基、烷基亚磺酰基、烷基磺酰基、烷氧基羰基、氨基磺酰基、氨基、取代氨基、氨基甲酰基、烷基氨基甲酰基、酰基或羧基; R2 是氢原子或低级烷基;R3 是氢原子、低级烷基或芳烷基; R4 是氢原子、卤素原子、低级烷基、羟基、烷氧基、酰基、烷氧羰基、硝基、氨基、取代氨基丙基、氨基甲酰基、烷基氨基甲酰基或酰氧基;R5 是低级烷基、氰基、氨基甲酰基、羧基、酰基、酰氧基、烷氧基、烷氧羰基、三卤甲基或羟基;以及 n 是 2 至 6 的整数。]
