Investigations of the anti-inflammatory properties of parthenolide, and feverfew have focused on suppression of primary inflammatory endpoints such as platelet aggregation [1] and carrageenan-induced mouse [2] and rat [3] paw edema. Additional studies have evaluated parthenolide’s inhibitory effect on inflammatory mediators including activity and expression of cyclooxygenase (COX) [4,5], generation of prostaglandins [6,7], and leukotrienes (LT) [4] and expression of proinflammatory cytokines [5,8]. Most recently, the compound was found to inhibit activation of transcription factor nuclear factor (NF)-?B [9-12]. Parthenolide, a major sesquiterpene lactone present in extracts of the herb Feverfew, has been investigated for its inhibitory effects on mediators of inflammation, including the proinflammatory cytokines. Although parthenolide’s anti-inflammatory effects have been investigated in vitro, little in vivo data are available. Moreover, the molecular mechanisms for these inhibitory effects are not fully understood. The objective of this study was to test the hypothesis that parthenolide suppresses lipopolysaccharide (LPS)-induced serum (interleukin) IL-6, tumor necrosis factor (TNF)-?, IL-1? and cyclooxygenase (COX)-2 expression in mice as indicated by reduced splenic and liver mRNA levels [13].
