1-O-Acetylbritannilactone(Inulicin) is a sesquiterpene isolated from the medicinal plant Inula britannica; anticancer and anti-inflammation acitvity. IC50 value: Target: in vitro: 1-O-Acetylbritannilactone significantly reduced melanin production in a dose-dependent manner with IC50 value of 13.3 uM. inhibited melanogenesis by activating extracellular signal-regulated kinase (ERK) and Akt signaling and also inhibiting cAMP related binding protein, which regulates its downstream pathway, including tyrosinase, tyrosinase related protein-1 and TRP-2 . ABL (5, 10, 20 micrommol/l) had several concentration-dependent effects, including inhibition of lipopolysaccharide (LPS)-induced PGE(2) production and COX-2 expression, and blockade of NF-kappaB activation and translocation . 1-O-Acetylbritannilactone is a potent inhibitor of LPS-stimulated VSMC inflammatory responses through blockade of NF-kappaB activity and inhibition of inflammatory gene COX-2 expression.
