embelin embelin embelin (2,5-dihydroxy-3-undecyl-1,4-benzoquinone) is a naturally occurring para-benzoquinone isolated from dried berries of embelia ribes plants. embelin has a wide spectrum of biological activities, including antioxidant, antitumor, anti-inflammatory, analgesic, anthelmintic, antifertility and antimicrobial. several studies have reported antidiabetic activity of embelin embelin treatment significantly decreased paraquat‐induced lung injury through suppressing oxidative stress, inflammatory cascade (inflammatory cytokines release), and mapk/nf‐κb signaling pathway in paraquat‐intoxicated rats embelin and embelin derivatives selectively inhibits 5-lox and microsomal prostaglandin e2 synthase-1 embelin names preferred iupac name 2,5-dihydroxy-3-undecylcyclohexa-2,5-diene-1,4-dione other names embelic acid, emberine identifiers cas number 550-24-3 y 3d model (jsmol) interactive image chebi chebi:4778 chembl chembl221137 chemspider 3105 echa infocard 100.008.164 ec number 208-979-8 kegg c10342 pubchem cid 3218 unii shc6u8f5er y comptox dashboard (epa) dtxsid80203537 inchi inchi=1s/c17h26o4/c1-2-3-4-5-6-7-8-9-10-11-13-16(20)14(18)12-15(19)17(13)21/h12,18,21h,2-11h2,1h3key: irsfldgtohbadp-uhfffaoysa-n smiles cccccccccccc1=c(c(=o)c=c(c1=o)o)o properties chemical formula c17h26o4 molar mass 294.391 g·mol−1 hazards ghs labelling: pictograms signal word warning hazard statements h361 precautionary statements p201, p202, p281, p308+p313, p405, p501 except where otherwise noted, data are given for materials in their standard state (at 25 °c , 100 kpa). infobox references
