title: The studies of the mechanism of antiinflammatory action of 2-(5-ethylpyridin-2-yl)benzimidazole (KB-1043).
abstract: The mechanism of the antiinflammatory activity of 2-(5-ethylpyridin-2-ly)benzimidazole (KB-1043), a new benzimidazole derivative with antiinflammatory, analgesic and antipyretic activities, is described. KB-1043 inhibits the emigration of leucocytes and the exudation of protein into the site of injury. KB-1043 possesses also a potent membrane stabilizing activity. Although KB-1043, in vitro, did not inhibit the enzyme activity, the increase of enzyme activity at the site of injury was inhibited by the oral administration of KB-1043. The inhibitory effect of KB-1043 on prostaglandin synthesis was slightly weaker than that of acetylsalicylic acid (ASA). The antiinflammatory effect of DB-1043 was observed also in adrenalectomized rats and spinalectomized rats.
