rat MCHR1 7 nM (Ki) |
CYP3A4 13 μM (EC50) |
BMS-819881 (Compound 27) is 99.8% binds to rat serum proteins and rat MCHR1 Ki is 7 nM. FLIPR-based assays establish that BMS-819881 is a potent and highly selective MCHR1 functional antagonist. BMS-819881 (Kb=32 nM) effectively blocks MCH stimulated Ca2+ mobilization in heterologous cells overexpressing MCHR1 but fails to inhibit MCH mediated Ca2+ mobilization of cells expressing MCHR2 at 10 μM. No activity is observed upon screening BMS-819881 at 10 μM versus a panel of 20 GPCRs associated with feeding homeostasis. The percent of BMS-819881 binds to serum proteins is species dependent ranging from 99.8%, 99.6%, and 99.3%, respectively, for rat, dog, and monkey. When BMS-819881 is screened for cytochrome P450 (CYP) activity, EC50 values for CYP1A2, CYP2C9, CYP2C19, CYP2D6 are >40 μM; however, the CYP3A4 EC50 is 13 μM[1].

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

Protokoll
Membranes from stably transfected HEK-293 cells expressing a mutated (E4Q, A5T) hMCHR1 receptor are prepared and differential centrifugation. Binding experiments are carried out with 0.5-1.0 μg of membrane protein incubated in a total of 0.2 mL in 25 mM HEPES (pH 7.4) with 10 mM MgCl2, 2 mM EGTA, and 0.1% BSA (binding buffer) for 90 min. For competition binding assays, reactions are carried out in the presence of 0.06–0.1 nM [Phe13, [125I]Tyr19]MCH and increasing concentrations of unlabeled test molecules. Reactions are terminated by rapid vacuum filtration over 96-well GFC Unifilter plates precoated with 0.075 mL of binding buffer containing 1% BSA and washed 3 times with 0.4 mL of PBS (pH 7.4) containing 0.01% TX-100. Filters are dried, 0.05 mL of MicroScint 20 is added to each well, and radioactivity is subsequently quantified by scintillation counting on a TopCount microplate scintillation counter. Inhibitory constants are determined by nonlinear least-squares analysis using a four-parameter logistic equation[1].

Stable HEK-293 cells expressing human MCHR1 or MCHR2 receptor are plated at a density of 50 000 cells/well in 96-well polylysine coated plates and cultured overnight in DMEM (high glucose (4.5 g/mL), 25 mM HEPES, pH 7.4, 10% fetal bovine serum, 1 mM NaCl) at 37°C, 5% CO2 conditions. For assay, the medium is replaced with 90 mL per well dye solution consisting of 3.8 mM Fluo4 AM, 0.04% Pluronic F-127, and 2.5 mM Probencid in base buffer (Hank’s balanced salt solution, 25 mM HEPES, 0.1% BSA). Dye solution is allowed to “load” for 1 h at room temperature in subdued light. Dye is subsequently removed and replaced with 75 mL of base buffer and 75 mL of diluted test compound (e.g., BMS-819881; 10 μM) and incubated for an additional 15 min. Test compound dilution plates are prepared by serial diluting test and reference compounds from 100% DMSO stocks first 1:50 in base buffer and then serially (1:3.26) in base buffer containing 2% DMSO to generate 12 half log test concentrations[1].
