Product Description
BMS-986122 is a potent and selective positive allosteric modulator (PAM) of the μ-opioid receptor (μ-OR). BMS-986122 displays orthosteric agonist-mediated enhancement of beta-arrestin recruitment, adenylyl cyclase inhibition, and G protein activation. BMS-986122 enhances DAMGO-mediated binding of [35S]GTPγS in mouse meninges.
Biological Activity I Assay Protocols (From Reference)
ln Vitro
BMS-986122 promotes the recruitment of β-arrestin in U2OS-OPRM1 human osteosarcoma cells that express u-opioid receptors in response to endorphin 1 (EC50=3 μM). BMS-986122 upregulates the suppression of forskolin-stimulated adenylyl cyclase activity in CHO cells that express human recombinant u-opioid linkers, which is activated by endorphin 1 (EC50=8.9 μM). In mouse meninges, BMS-986122 increases DAMGO-mediated binding of [35S]GTPγS and, to some extent, seems to be a positive affinity modulator of DAMGO binding via u-opioid uptake [1]. In CHO cells expressing human u-opioid receptors, BMS-986122 enhances the ability of the endogenous opioid methionine-enkephalin (Met-Enk) to stimulate G protein activity, while it is inactive on its own and less effective than β-arrestin Enhanced G-protein activation recruitment. BMS-986122 amplifies Met-Enk's ability to suppress GABA release in the periaqueductal gray matter, a critical area for anti-injury effects [2]. BMS-986122 possesses the similarly related δ-OR and is selective for μ-OR. A quiet allosteric modulator of δ-OR and κ-OR is BMS-986122 [3].

Solubility Data
Solubility (In Vitro)
DMSO : ~100 mg/mL (~222.83 mM)
Solubility (In Vivo)
Solubility in Formulation 1: 2.5 mg/mL (5.57 mM) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), suspension solution; with sonication.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL.
Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution.

Solubility in Formulation 2: ≥ 2.5 mg/mL (5.57 mM) (saturation unknown) in 10% DMSO + 90% Corn Oil (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 900 μL of corn oil and mix evenly.

 (Please use freshly prepared in vivo formulations for optimal results.)

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.

What volume of a given 10 mM stock solution is required to make 25 ml of a 25 μM solution?
Using the equation C1V1 = C2V2, where C1=10 mM, C2=25 μM, V2=25 ml and V1 is the unknown:
  • Enter 10 into the Concentration (Start) box and choose the correct unit (mM)
  • Enter 25 into the Concentration (End) box and select the correct unit (mM)
  • Enter 25 into the Volume (End) box and choose the correct unit (mL)

Biological Data
  • Effect of μ-PAMs BMS-986121 and BMS-986122 on endomorphin-I stimulated β-arrestin recruitment in U2OS-OPRM1 cells. Both BMS-986121 (A) and BMS-986122 (B) produced concentration-dependent leftward shifts in the β-arrestin–recruitment response to the agonist endomorphin-I. The data were analyzed simultaneously using an allosteric ternary complex model to provide Kb and cooperativity factor (α) values for each compound (SI Materials and Methods). Calculated EC50 values (nanomoles per liter) for endomorphin-I at each concentration of compound are shown in the legend of each graph. The fold leftward shift in EC50 values for endomorphin-I in the presence of increasing concentrations of PAM compound is presented (C). Data are represented as means ± SEM of four experiments.[1].Burford NT, et al. Discovery of positive allosteric modulators and silent allosteric modulators of the μ-opioid receptor. Proc Natl Acad Sci U S A. 2013;110(26):10830-10835.
  • Effect of μ-PAMs on inhibition of forskolin-stimulated cAMP accumulation in CHO-μ cells. Both BMS-986121 (A) and BMS-986122 (B) increased the effect of a low (∼EC10; 30 pM) concentration of endomorphin-I (PAM-detection mode) in a concentration-dependent manner. The compounds also showed some agonist activity when added alone (agonist-detection mode). For agonist-detection mode, 0% activity represents vehicle (basal) activity. For PAM-detection mode, 0% is normalized to the response to an ∼EC10 (30 pM) concentration of endomorphin-I. The 100% response represents the response to an Emax concentration of endomorphin-I (10 nM) in both agonist and PAM-detection modes. Data are represented as means ± SEM of three experiments.[1].Burford NT, et al. Discovery of positive allosteric modulators and silent allosteric modulators of the μ-opioid receptor. Proc Natl Acad Sci U S A. 2013;110(26):10830-10835.
  • Effect of μ-PAM, BMS-986122, on μ-opioid agonist-stimulated [35S]GTPγS binding in membranes from C6μ cells and mouse brain and DAMGO binding affinity in C6μ cell membranes. [35S]GTPγS binding in C6μ membranes was determined as described in Methods and Materials. The EC50 of DAMGO to stimulate [35S]GTPγS binding was shifted to the left sevenfold in the presence of 10 µM BMS-986122 (A). The maximal stimulation by DAMGO was not affected by BMS-986122. The potency of morphine to stimulate [35S]GTPγS binding was shifted to the left threefold in the presence of 10 µM BMS-986122, and the Emax of morphine compared with DAMGO was increased by BMS-986122 (B). BMS-986122 (10 µM) also produced a sixfold leftward shift in DAMGO affinity in DAMGO competition-binding studies with [3H]diprenorphine (C) but had no effect on [3H]diprenorphine-binding affinity (Fig. S3A and Table S1). The EC50 of DAMGO to stimulate [35S]GTPγS binding in membranes from mouse brain was shifted to the left 4.5-fold in the presence of 10 µM BMS-986122 (D). Basal [35S]GTPγS binding (femtomoles bound per milligram of protein: 3.2 ± 0.2 in C6μ cells and 4.8 ± 0.4 in mouse brain) was not affected by 10 μΜ BMS-986122. Shown are the combined means ± SEM data from three to seven separate assays, each performed in duplicate.[1].Burford NT, et al.
