製品説明

Oveporexton (TAK-861) is an orally active and selective orexin receptor 2 (OX2R) agonist with an EC50 of 2.5 nM. Oveporexton exhibits 3000-fold selectivity for OX2R over OX1R. Oveporexton can be used for the study of hypersomnia disorders including narcolepsy[1][2].

IC50 & Target[2]

OX2 Receptor

2.5 nM (EC50)

OX1 Receptor

7500 nM (EC50)

体外実験

Oveporexton potently activates recombinant OX2R (EC50 of 2.5 nM) and weakly activates OX1R (EC50 of 7500 nM)[2].
Oveporexton (10-1000 nM) induces dose-dependent depolarization of the membrane potential in histaminergic neurons in the mouse tuberomammillary nucleus with an EC50 of 31.7 nM[2].

体内実験

Oveporexton (0.03-10 mg/kg; p.o.) improves narcolepsy-like phenotype in mice, significantly increasing total waking time[2].
Oveporexton (1 mg/kg; p.o.) significantly increases wakefulness time in cynomolgus monkeys[2].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model: Male C57BL/6J mice (3 weeks old for slice electrophysiology), male OX2R KO mice (18 weeks old), male orexin/ataxin-3 mice and their WT littermates (22-29 weeks old)[2]
Dosage: For WT mice: 0.3 mg/kg, 1 mg/kg, 3 mg/kg, 10 mg/kg; For OX2R KO mice: 10 mg/kg; For orexin/ataxin-3 mice: 0.03 mg/kg, 0.1 mg/kg, 0.3 mg/kg, 1 mg/kg
Administration: Oral administration; single dose for most experiments, except for the repeated administration study in orexin/ataxin-3 mice where it was administered once daily for 14 days in the sub-chronic treatment group
Result: Increased total wakefulness time and decreased NREM and REM sleep times (in WT mice).
Had no effect on sleep-wake parameters (in OX2R KO mice).
Increased wakefulness, decreased NREM sleep, improved wakefulness fragmentation, and reduced cataplexy -like episodes (in orexin/ataxin-3 mice).

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: ≥ 5 mg/mL (9.61 mM); Clear solution

    This protocol yields a clear solution of ≥ 5 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (50.0 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: ≥ 5 mg/mL (9.61 mM); Clear solution

    This protocol yields a clear solution of ≥ 5 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (50.0 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.
