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.
