helenalin
Sign in to saveAlso known as 6alpha,8beta-dihydroxy-4-oxoambrosa-2,11(13)-dien-12-oic acid 12,8-lactone, Helenalin A, (3aS)-3,3aalpha,4alpha,4a,7aalpha,8,9,9aalpha-octahydro-4-hydroxy-4abeta,8alpha-dimethyl-3-methyleneazuleno(6,5-b)-furan-2,5-dione
Helenalin, or (-)-4-Hydroxy-4a,8-dimethyl-3,3a,4a,7a,8,9,9a-octahydroazuleno[6,5-b]furan-2,5-dione, is a toxic sesquiterpene lactone which can be found in several plants such as Arnica montana and Arnica chamissonis Helenalin is responsible for the toxicity of the Arnica spp. Although toxic, helenalin possesses some in vitro anti-inflammatory and anti-neoplastic effects. Helenalin can inhibit certain enzymes, such as 5-lipoxygenase and leukotriene C4 synthase. For this reason the compound or its derivatives may have potential medical applications.
