Noladin ether (2-Arachidonyl glycerol ether) is a stable analog of the endogenous cannabanoid 2-Arachidonylglycerol (2-AG) with selectivity for CB1 receptors. Noladin ether is a CB1 agonist. The Ki values for CB1 vs CB2 receptors are 21.2 nM and 3 mM, respectively. Noladin ether induces sedation and has modest antinociceptive activity in vivo, and reduces inter ocular pressure after administration in the eye. 2-Arachidonyl glycerol ether (2-AG ether) is supplied as a solution in ethanol. To change the solvent, simply evaporate the ethanol under a gentle stream of nitrogen and immediately add the solvent of choice. Solvents such as DMSO and dimethyl formamide purged with an inert gas can be used.
