Description
(±)19(20)-EDP ethanolamide is an ω-3 endocannabinoid epoxide and cannabinoid (CB) receptor agonist (EC
50s = 108 and 280 nM for CB
1 and CB
2, respectively). It is produced through direct epoxygenation of docosahexaenoyl ethanolamide (DHEA; ) by cytochrome P450 (CYP) epoxygenases.
1,2 (±)19(20)-EDP ethanolamide (25 μM) reduces the viability of 143B metastatic osteosarcoma cells.
2 It decreases the production of IL-6 and increases the production of IL-10 when used at concentrations ranging from 2.5 to 10 μM in BV-2 microglia stimulated by LPS and decreases LPS-induced cytotoxicity when used at concentrations ranging from 5 to 10 μM. It also decreases nitrite production when used at a concentration of 7.5 μM, an effect that can be partially reversed by the CB
2 receptor antagonist AM630 and the PPARγ antagonist GW 9662 . (±)19(20)-EDP ethanolamide induces vasodilation of isolated preconstricted bovine coronary arteries (ED
50 = 1.9 μM) and reduces tube formation by human microvascular endothelial cells (HMVECs) in a Matrigel? assay.
