The synthesis and the pharmacological activity of a series of 1,5-diarylimidazoles developed as potent and selective cyclooxygenase-2 (COX-2) inhibitors are described. The new compounds were evaluated both in vitro (COX-1 and COX-2 inhibition in human whole blood) and in vivo (carrageenan-induced paw edema, air-pouch, and hyperalgesia tests). Modification of all the positions of two regioisomeric imidazole cores led to the identification of 4-[4-chloro-5-(3-fluoro4-methoxyphenyl)imidazol-1-yl]benzenesulfonamide (UR-8880, 51f) as the best candidate, which is now undergoing Phase I clinical trials.

Compounds of formula I wherein: one of X or Y represents N and the other represents C; R1 represents hydrogen, methyl, halogen, cyano, nitro, -CHO, -COCH3 or -COOR4; R2 represents optionally-substituted aryl or heteroaryl; R3 represents C1-8 alkyl, C1-8 haloalkyl or -NR4R6; R4 represents hydrogen, C1-8 alkyl or arylC0-8 alkyl; R6 represents hydrogen, C1-8 alkyl, arylC1-8 alkyl, -COR8 or -COOR8; R8 represents C1-8 alkyl or C1-8 haloalkyl; aryl in the above definitions represents phenyl or naphthyl; and heteroaryl in the above definitions represents pyridine, pyrazine, pyrimidine or pyridazine, which can be optionally fused to a benzene ring. These compounds are useful as cyclooxygenase-2 inhibitors.
