花生四烯酸乙醇胺是人类发现的第一个内源性大麻素类似物,近年来,关于花生四烯酸乙醇胺含量的改变和疾病之间的关系的文献报道越来越多,有研究者认为,大麻受体内源性主要配体花生四烯酸乙醇胺在许多疾病中可能扮演了疾病前兆性指示物或疾病发生标志物的角色。
将富含花生四烯酸的微生物藻油(花生四烯酸含量43.69%,其他包含的脂肪酸有6.68%棕榈酸、5.81%硬脂酸、5.95%油酸、8.93%亚油酸、2.27%亚麻酸、4.2%花生三烯酸、3.2%山嵛酸、10.62%木焦油酸等)与单乙醇胺进行酰胺化反应。其中微生物藻油与单乙醇胺的摩尔比为1:3,按照质量体积比为1:1添加反应介质(正己烷:无水乙醇=1:1,v/v),0.3%的甲醇钠的甲醇溶液作为碱性催化剂,在25℃下搅拌反应2.5h,结束反应。经HPLC分析,脂肪酸乙醇酰胺含量为62.5%。按照尿素:95%乙醇=1:2(m/v)于70℃下加热回流,待尿素完全溶解后,按混合脂肪酸单乙醇酰胺:尿素=1:2(m/m)加入脂肪酸单乙醇酰胺,继续回流至溶液变澄清透明,停止反应并自然冷却至室温。然后在-40℃下脲包12h,取出后迅速抽滤分离,并用乙醇洗涤结晶物2~3次,合并滤液,移至分液漏斗,再加入无水乙醚和热水,轻轻震荡,充分萃取几次,静置分层。得到水相为尿素溶液,经一次低温结晶,滤液浓缩后二次结晶可得到尿素晶体回收干燥利用。合并有机相,用无水Na2SO4干燥,旋蒸去除溶剂,得到较高纯度的花生四烯酸乙醇胺。所得花生四烯酸乙醇胺纯度从42.17%提高到63.18%。

Anandamide, acting via CB2 receptors, alleviates lipopolysaccharide (LPS)-induced neuroinflammation in rat primary microglial cultures. The endocannabinoid system modulates both neuronal and immune functions through two protein-coupled cannabinoid receptors (CB1 and CB2), although endocannabinoids, especially Anandamide (AEA), can activate numerous other receptors like PPARS, TRPV1, and GPR18/GPR55.
Anandamide is an endocannabinoid binding both CB1R and CB2R. To evaluate the impact of CBR activation on whole-body glucose homeostasis, glucose tolerance is assessed after a single intraperitoneal Anandamide injection (10 mg/kg). The increase in glycemia in response to glucose ingestion is considerably smaller in mice treated with Anandamide compared with control, and this is associated with an improvement of glucose tolerance as illustrated by the AUC 0-2h calculations.
