Lipopolysaccharide-induced pyrexia model was used to evaluate antipyretic activity in Wistar rats. The antiin flammatory and antipyretic mechanisms were evaluated by detecting prostaglandins E2, nitric oxide, interleukin-1b and tumour necrosis factora levels using appropriate reagents and ELISA kits.Results: The results revealed that K-601 reduced the level of in flammations in both antiin flammatory models in a dose-dependent manner. The same was true for the antipyretic model. The possible mechanisms of actions were through the inhibition of prostaglandins E2, interleukin-1b, tumour necrosis factora and nitric oxide.Conclusions: K-601 has proven anti-in flammatory and antipyretic actions. The findings provide a scientific basis for the use of K-601 as anti-in flammatory and antipyretic agent in traditional Chinese medicinal practice.展开更多
Six isochromano [4, 3-c]pyrazole derivatives were synthesized from isochroman-4-one as starting compound. Some of the products show a significant anti-inflammatory activi-ty.
