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.
该发明涉及具有5-HT7受体拮抗活性的新型磺胺类化合物,其制备方法,含有它们的组合物以及它们在治疗中枢神经系统和其他疾病中的用途。
其中:
