Embelin (2,5-dihydroxy-3-undecyl-1,4-benzoquinone) is a naturally occurring para-benzoquinone isolated from dried berries of Embelia ribes plants.[1][2] Embelin has a wide spectrum of biological activities, including antioxidant, antitumor, anti-inflammatory, analgesic, anthelmintic, antifertility and antimicrobial.[3][4][5] Several studies have reported antidiabetic activity of embelin[6] 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[7] Embelin and embelin derivatives selectively inhibits 5-LOX and microsomal prostaglandin E2 synthase-1[8][9]
