  Synthesis of 1,5-diarylhaloimidazole analogs and their inhibitory activities against PGE2 production from LPS-treated RAW 264.7 cells

  摘要：

  A number of 1,5-diarylimidazole analogs were synthesized and evaluated their inhibitory activities of cyclooxygenase-2 catalyzed prostaglandin E-2 production. Reactions of 1,5-diarylimidazoles with halogenating reagents (NCS, NBS, NIS) afforded halogenated analogs. Among the analogs tested, compounds Ib, Ha, IIb and IIe exhibited significantly improved inhibitory activities against COX-2-mediated PGE(2) production from LPS-induced RAW 264.7 cells compared to those of the parent 1,5-diarylimidazoles. Especially, the analogs Ib (IC50 = 0.55 mu M) and Ha (IC50 = 0.58 mu M) showed best results. Halogenation on the 1,5-diarylimidazole ring enhanced inhibitory activities against COX-2 catalyzed PGE(2) production, however, inhibitory activities were significantly varied by position(s) and species of the substituted halogen(s).

  1,5-Diarylimidazoles with strong inhibitory activity against COX-2 catalyzed PGE2 production from LPS-induced RAW 264.7 cells

  摘要：

  A series of 1,5-diarylimidazoles with 4-methylsulfonylphenyl group were prepared and evaluated for the inhibitory activities against COX-2 catalyzed PGE(2) production from LPS-induced RAW 264.7 cells. Most of synthesized 1,5-diarylimidazoles exhibited strong inhibitory activities regardless of the position of the 4-methylsulfonylphenyl group. The 1,5-diarylimidazoles with a halogen atom (3c-3h, 3n-3p) gave mostly excellent inhibitory activities regardless of the position and species of the halogen atom. Whereas the 1,5-diarylimidazoles with two fluorine atoms (3k, 3l, 3r, 3s) showed rather reduced inhibitory activities. (C) 2010 Elsevier Ltd. All rights reserved.
