    제품 설명

    Setmelanotide (RM-493) is a selective melanocortin 4 receptor (MC4R) agonist with EC50s of 0.27 nM and 0.28 nM for human and rat MC4R, respectively[1].

    IC50 & Target

    Ki:3.9 nM (hMC1R), 10 nM (hMC3R), 2.1 nM (hMC4R), 430 nM (hMC5R), 2.7 nM (rMC4R)[1]
    EC50: 5.8 nM (hMC1R), 5.3nM (hMC3R), 0.27 nM (hMC4R), 0.28 (rMC4R), 1600 nM (hMC5R)[1]
    In Vitro

    Melanocortin receptor agonists act in the brain to regulate food intake and body weight and, independently of these actions. Setmelanotide exhibits agonist activity to human and rat MC4R with Kis of 2.1 and 2.7 nM and EC50s of 0.27 and 0.28 nM, respectively[1].

    Setmelanotide Related Antibodies
    In Vivo

    Inhibition of refeeding after an overnight fast by Setmelanotide is dependent on functional MC4R, and does not require MC3R. BIM-22493 acutely improves glucose homeostasis. Lepob/Lepob mice treated with BIM-22493 exhibits significantly improved glucose clearance when compared to controls. Chronic BIM-22493 treatment was associated with significantly lower levels of serum glucose and HOMA-IR values[1].
    Treatment with setmelanotide results in transient decreases in food intake (35%), with persistent weight loss over 8 weeks of treatment (13.5%) in a diet-induced obese nonhuman primate model[2].

    In Vivo:

    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.

    • Protocol 1

      Add each solvent one by one:  10% DMSO    40% PEG300    5% Tween-80    45% Saline

      Solubility: ≥ 2.5 mg/mL (2.24 mM); Clear solution

      This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).

      Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.

      Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
    • Protocol 2

      Add each solvent one by one:  10% DMSO    90% (20% SBE-β-CD in Saline)

      Solubility: ≥ 2.5 mg/mL (2.24 mM); Clear solution

      This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).

      Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.

      Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.

    Help & FAQs
    • Do most proteins show cross-species activity?

      Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
