The present invention relates to tetrahydroquinazoline-2,4-diones derivatives of the formula (I):
pharmaceutically acceptable salts thereof, wherein A is (CH2)n where n is equal to 0, 1 or 2; U is CH2, NH, or NR3, R1 and R2 are selected independently from H, (C1-C6)alkyl, Cl, F, CN, nitro, CF3, —NHC(O)R6 and —OR7, or R1 and R2, together with the atoms to which they are attached, form a carbocyclic or heterocyclic five- or six-membered ring, R3 is selected from the group consisting of H, (C1-C6)malkyl, C(═O)—(C1-C6)alkyl, where m=1 or 2; R4 and R5 are selected from H, (C1-C6)alkyl, Cl, F, —CF3, —CN, —NHC(═O)R6, —OR7, a 5-to 7-membered aryl or heteroaryl ring, where m, R6 and R7 are as defined above; and R6 and R7 are selected independently from H, (C1-C6)alkyl or a 5- to 7-membered aryl or heteroaryl ring; V is CH, CR3, or N; W is CH2, C(O), or S(O)2; X is C or N; and Y is CH, CR1,CR2, or N. The invention also relates to pharmaceutical compositions containing the same and to methods of use thereof, including in the inhibition of serotonin reuptake, the inhibition of the binding of 5-HT2A serotonin receptors and the treatment of diseases, conditions or disorders of the central nervous system. Further, the present invention is also directed to methods for the preparation of 4-(4-phenyl-1,2,3,6-tetrahydropyridin-1-yl)-propyl-1,2,3,4-tetrahydroquinazoline-2,4-dione compounds and intermediates useful thereof.
本发明涉及式(I)的四氢喹唑啉-2,4-二酮衍生物:其药学上可接受的盐,其中A为(CH2)n,其中n等于0、1或2;U为CH2、NH或NR3,R1和R2分别选自H、(C1-C6)烷基、Cl、F、CN、硝基、CF3、—NHC(O)R6和—OR7,或R1和R2与它们附着的原子一起形成一个碳环或杂环的五元或六元环,R3选自H、(C1-C6)烷基、C(═O)—(C1-C6)烷基,其中m=1或2;R4和R5选自H、(C1-C6)烷基、Cl、F、—CF3、—CN、—NHC(═O)R6、—OR7、5至7成员芳基或杂芳基环,其中m、R6和R7如上所定义;R6和R7独立选择自H、(C1-C6)烷基或5至7成员芳基或杂芳基环;V为CH、CR3或N;W为CH2、C(O)或S(O)2;X为C或N;Y为CH、CR1、CR2或N。该发明还涉及含有相同化合物的药物组合物以及使用方法,包括在抑制5-羟色胺再摄取、抑制5-HT2A 5-羟色胺受体结合和治疗中枢神经系统疾病、状况或紊乱的方法。此外,本发明还涉及用于制备4-(4-苯基-1,2,3,6-四氢吡啶-1-基)-丙基-1,2,3,4-四氢喹唑啉-2,4-二酮化合物和有用中间体的方法。
