A series of studies have recently demonstrated that the release of
interleukin 1β induced by monosodium urate crystals is central to the
experimental gouty arthritis. Elaeagnus pungens has been
traditionally used for the treatment of gouty arthritis in China for more
than thousands years. However, there is still little known about the active
ingredients and mechanisms of E. pungens against gouty arthritis.
Emodinol, as a major triterpene compound in E. pungens, has been
seldom reported to have an effect on gouty arthritis. Therefore, the
potential beneficial effects and mechanisms of emodinol on gouty arthritis
were investigated in this study. Results showed that it significantly
ameliorated the hyperalgesia, inflammation, and levels of multiple
proinflammatory cytokines in monosodium urate crystals-treated mice. These
findings elucidate that emodinol exhibits a prominent effect on improving
symptoms of acute gouty arthritis induced by monosodium urate crystals
through inhibiting the generation of proinflammatory cytokines.
