RT Journal Article T1 Flavonoids and a Sesquiterpene Lactone from Tanacetum microphyllum Inhibit Anti-Inflammatory Mediators in LPS-Stimulated Mouse Peritoneal Macrophages A1 Abad Martínez, María José A1 Bermejo Benito, Paulina A1 Álvarez, Maria A1 Guerra Guirao, José Antonio A1 Silván, Ana María A1 Villar Del Fresno, Ángel AB In our ongoing research into anti-inflammatory compounds from Tanacetum microphyllum, four naturally occurring flavonoids (santin, ermanin, centaureidin and 5,3′-dihydroxy-4′-methoxy-7- methoxycarbonylflavonol) and one sesquiterpene lactone (hydroxyachillin) isolated from this plant, were evaluated as potential inhibitors of some macrophage functions involved in the inflammatory process. These five compounds significantly inhibited lipopolysaccharide (LPS)-induced nitric oxide (NO) and prostaglandin E2 (PGE2) in a concentration-dependent manner. In the tumour necrosis factor-α (TNF-α) assay, only centaureidin and hydroxyachillin significantly inhibited the accumulation of TNF-α. These results indicate that these compounds may contribute to the anti-inflammatory properties of T. microphyllum.
