生物活性
Eicosapentaenoyl ethanolamide (EPEA) is a lipid mediator that has been found to suppress lifespan extension resulting from dietary restriction inC.elegansand also to have antiproliferative and anti-inflammatory actions. InC. elegans, it is believed to act as a metabolic signal that couples nutrient availability with growth and lifespan. EPEA is a member of the N-acylethanolamines (NAEs), lipid-derived signaling molecules that include the mammalian endocannabinoid arachidonoyl ethanolamide (AEA). In mammals, NAEs are believed to act primarily through cannabinoid receptors, although they can also interact with a variety of other targets, and EPEA has been shown to act as a CB1 and CB2 receptor agonist. However,C.elegansdoes not possess clear orthologues of the mammalian cannabinoid receptors which suggests that there are unidentified NAE receptors in nematodes that are possibly conserved mediators of NAE signaling.

例如,依据体表面积折算法,将化合物用于小鼠的剂量20 mg/kg 换算成大鼠的剂量,需要将20 mg/kg 乘以小鼠的Km系数(3),再除以大鼠的Km系数(6),得到化合物用于大鼠的等效剂量为10 mg/kg。
