ChEMBL null: The Ki (binding affinity) for u opioid receptors was determined using a competitive displacement assay as previously described in Neumeyer (Journal of Med. Chem. 2012, p 3878), which is incorporated herein in its entirety. Briefly, membrane protein from CHO (Chinese Hamster Ovarian) cells that stably expressed the cloned human u opioid receptor were incubated with 12 different concentrations of the compound set forth herein in the presence of 0.25 nM [3H]DAMGO (see Tiberi et al., Can. J. Physiol. Pharmacol. 1988, Vol. 66, p 1368, which is incorporated by reference herein in its entirety) in a final volume of 1 mL of 50 mM Tris-HCl, pH 7.5 at 25° C. Incubation times of 60 min were used for [3H]DAMGO (see Gulati et al., Life Sci. 1990, Vol. 47, p 159, which is incorporated by reference herein in its entirety).

ChEMBL Functional Assay (GTPgammaS Binding): The EC50 and Imax for mu opioid receptors was determined using a [I35S]GTPgammaS binding assay. This assay measures the functional properties of a compound by quantifying the level of G-protein activation following agonist binding in studies using stably transfected cells, and is considered to be a measure of the efficacy of a compound. Membranes from CHO (Chinese Hamster Ovary) cells that stably expressed the cloned human Mu opioid receptor were used in the experiments. Specifically, in a final volume of 0.5 mL, 12 different concentrations of each test compound were incubated with 7.5 ug of CHO cell membranes that stably expressed the human mu opioid receptor. The assay buffer consisted of 50 mM Tris-HCl, pH 7.4, 3 mM MgCl2, 0.2 mM EGTA, 3 uM GDP, and 100 mM NaCl. The final concentration of [35S]GTPgammaS was 0.080 nM. Nonspecific binding was measured by inclusion of 10 uM GTPgammaS. Binding was initiated by the addition of the membranes. F 7.47 pEC50 34 nM EC50 US-9133125-B2.
