Anti-inflammatory activity of an imidazopyridine derivative (miroprofen).
Anti-inflammatory activity of 2-[p-(2-imidazo[1,2-a]pyridyl) phenyl]propionic acid (Y-9213, miroprofen) was studied on various experimental models. Miroprofen was found to be as active as indomethacin against the exudative inflammation such as pleuritis in rats induced by Evans blue-carrageenin and the peritonitis in mice induced by acetic acid, and against the local Shwartzman reaction in rabbits. Miroprofen also inhibited the formation of edema induced by carrageenin or kaolin in rats' paws at lower doses. Against the proliferation of connective tissues, miroprofen showed the inhibitory action at higher doses. The ulcerogenic activity of miroprofen in rats was less potent than that of indomethacin, and as active as that of phenylbutazone. These findings indicate that miroprofen may be more effective in suppressing pain responses and acute inflammation accompanied with increased vascular permeability.
