anandamide

Anandamide ((5Z,8Z,11Z,14Z)-N-(2-Hydroxyethyl)icosa-5,8,11,14-tetraenamide) 是一种免疫调节剂，通过大麻素受体 CB1 和 CB2 起作用，还通过中枢神经系统中的其他靶点起作用，如 GPR18/GPR55。

Linoleoyl ethanolamide 是脂肪酸乙醇酰胺。它可弱结合 CB1 和 CB2 受体，并分别抑制[3H]CP-55,940的结合，Ki 分别为 10 和 25μM。它在引起小鼠过氧化氢酶方面的效力是 anandamide 的4倍，且对睡眠时间无延长效果。

The acyl amides are a family of endogenous lipids that act as potent modulators of pain and inflammation. The best characterized members of this family are the arachidonoyl amides, which includes N-arachidonoyl ethanolamide (AEA; anandamide). N-palmitoyl glycine (PalGly) contains an 18-carbon saturated fatty acid that is amide-linked to glycine and is structurally similar to the phospholipid-derived N-acyl ethanolamines. Endogenously produced in rat skin and spinal cord, PalGly is present in 100-fold greater amounts in skin and 3-fold greater in brain compared to AEA. Injection of 0.43 μg PalGly in rat hindpaw inhibits heat-induced firing of nociceptive neurons in rat dorsal horn. PalGly treatment induces transient calcium influx in native dorsal root ganglion (DRG) cells and in the PTX-sensitive, DRG-like cell line F-11 (EC50 = 5.5 μM).
