The invention relates to novel sulfonamide compounds having 5-HT7 receptor antagonist activity, processes for their preparation, to compositions containing them and to their use in the treatment of CNS and other disorders.
wherein:
Q is phenyl or thienyl;
R1 is halogen, hydroxy, C1-6alkyl, CF3, OCF3 or C1-6alkoxy;
m is 0, 1, 2 or 3;
R2 is C1-4alkyl;
X is carbon or CH,
is a single bond when X is nitrogen or CH or
is a double bond when X is carbon,
D is a single bond, C═O, O or CH2 subject to the proviso that when X is nitrogen then D is not oxygen;
P is a 5 or 6 membered heteroaryl ring containing 1 to 3 heteroatoms selected from oxygen, nitrogen and sulphur, or a benzofused heteroaryl ring containing 1 to 3 heteroatoms selected from oxygen, nitrogen and sulphur;
R3 is C1-6alkyl optionally substituted by NR4R5, aryl, arylC1-6alkyl, C1 6alkoxy, C1-6alkylthio, cyano, hydroxy, nitro, halogen, CF3, C2F5, NR4R5, CONR4R5, NR4COR5, S(O)pNR4R5, CHO, OCF3, SCF3, CH2OR6, CO2R6 or COR6 where p is 0, 1 or 2 and R4, R5 and R6 are independently hydrogen, C1-6alkyl, aryl or arylC1-6alkyl;
n is 0, 1, 2 or 3.
