Inhibitory activities of 1,5-diarylimidazole analogs with methylthiophenyl group on prostaglandin $E_2$ ($PGE_2$) production from LPS-treated RAW 264.7 cells, were evaluated and compared with those of the corresponding analogs with 4-methanesulfonylphenyl group. Among the tested nineteen analogs with methylthiophenyl group, fourteen analogs showed strong inhibitory activities (>88%) when compared with the reference compound NS-398, and fifteen analogs have similar inhibitory activities with those of parent analogs with 4-methanesulfonylphenyl group. Those results suggest that most of 1,5-diarylimidazole analogs with methanesulfonylphenyl group can be also active even after they are metabolized by reduction.
