The invention refers to new compounds of formula (I), wherein A and B are selected from the group consisting of N and CH, with the condition that when A is N, B is N; R1 is selected from the group consisting of CH3 and NH2; R2 and R3 are selected from the group consisting of H, CH3, Br, Cl, COCH3 and OCH3; and R4, R5 and R6, are selected from the group consisting of H, F, Cl, Br, (C1-C3)-alkyl, trifluoromethyl, (C1-C3)-alkoxy and trifluoromethoxy. Compounds of formula (I) are prepared by reaction of a substituted aminoazine with a substituted 2-bromo-2-(4-R1-sulfonylphenyl)-1-phenylethanone in a polar solvent. These new compounds inhibit COX-2 with high selectivity over COX-1. They are useful for the treatment of inflamation and/or cyclooxygenase-mediated diseases, having the additional advantage of a reduced potencial for ulcerogenic effects.
该发明涉及公式(I)的新化合物,其中A和B选自N和CH的组,条件是当A为N时,B为N;R1选自CH3和NH2的组;R2和R3选自H、CH3、Br、Cl、COCH3和OCH3的组;R4、R5和R6选自H、F、Cl、Br、(C1-C3)-烷基、三氟甲基、(C1-C3)-烷氧基和三氟甲氧基的组。通过在极性溶剂中将取代的氨基嘧啶与取代的2-溴-2-(4-R1-磺酰基苯基)-1-苯基乙酮反应制备公式(I)的这些新化合物。这些新化合物对COX-2具有高选择性抑制作用,而对COX-1具有较低影响。它们可用于治疗炎症和/或环氧合酶介导的疾病,具有减少溃疡作用的额外优势。
