文摘

Several coumarin derivatives have been reported to present multiple biological activities. In this study, in vitro the compound IMMLG5521 (0.1, 1, 10 ¦ÌM) can inhibit the release of ¦Â-glucuronidase from PAF-stimulated polymorphonuclear leukocytes, the compound IMMLG5521 (0.1, 1, 10 ¦ÌM) can inhibit NO production and decrease TNF-¦Á and IL-¦Â release from LPS-stimulated RAW264.7 cells. In vivo, we evaluated the effect of IMMLG5521 on acute and chronic inflammation models. Our data showed that IMMLG5521 (6 mg/kg, 12 mg/kg) could inhibit xylene-induced ear swelling and cotton pellet-induced granuloma formation in mice. Taken together, the compound IMMLG5521 inhibited the release of inflammatory factors and mediators in vitro, decreased inflammation response in mice. The compound IMMLG5521 can inhibit inflammation in vitro and in vivo.
