OMDM-3 is a selective and metabolically stable anandamide cellular uptake (ACU)inhibitor(Ki of 16.6 μM).

Anandamide cellular uptake:ki:16.6 μM

OMDM-3 is anovel potent and selective inhibitors of ACU?and one 'hybrid' agonist of CB(1) and VR1 receptors (OMDM-6).?Unlike other compounds of the same type, OMDM-1, OMDM-2, and OMDM-6 were very stable to enzymatic hydrolysis by rat brain homogenates.OMDM-3 shows poor affinity for either CB1 (Ki=12.1 μM) or CB2 (Ki>10 μM) receptors in rat brain and spleen membranes, respectively;?OMDM-3 has almost no activity at vanilloid receptors in the intracellular calcium assay carried out with intact cells over-expressing the human VR1 (EC50≥10 μM), and no activity as inhibitors of FAAH in N18TG2 cell membranes (Ki>50 μM)[1].
