pubmed:abstractText |
Rapanone (2,5-dihydroxy-3-tridecyl-1,4-benzoquinone), a natural compound isolated from Myrsine guianensis growing in the Andean highlands of Colombia, was studied in different in vitro and in vivo models as a potential antioxidant and anti-inflammatory drug. Rapanone showed a mild anti-lipoperoxidative profile in rat liver microsomes and inhibited potently degranulation (IC(50) of 9.8 microM) and superoxide chemiluminescence (IC(50) of 3.0 microM) in human neutrophils. In addition, rapanone is a selective and potent human synovial PLA(2) inhibitor (IC(50) of 2.6 microM). In vivo experiments using the carrageenan paw oedema and the zymosan air pouch model in mice as well as the adjuvant arthritis model in rats have proved that rapanone is very efficient in controlling the inflammatory process by different administration routes.
