パルミトイルエタノールアミド

出典: フリー百科事典『ウィキペディア(Wikipedia)』

Palmitoylethanolamide、略称はPEA[1]、内因性脂肪酸アミドの一種であり[2][3]、抗炎症鎮痛作用がある[4]。天然に存在する生物学的に活性な脂質で、動物植物にも存在する[5]。PEAの主要な標的の1つはペルオキシソーム増殖剤活性化受容体(PPAR−α)であると考えられている[6][7]。PEAはカンナビノイド受容体GPR55およびGPR119に対しても親和性を有する[8]

研究と生産

[編集]

Palmitoylethanolamide、1957年に発見され[9][10]、食品や多くの生体内に生理活性成分として存在している[11]。消炎鎮痛薬としての適応症は1980年以前にさかのぼる。1990年代半ばには、PEAとの関係が記述されている[12]。2021年4月、中国に拠点を置く医薬品メーカー[13]CofttekはPEAの大量生産を導入した[14]
