SB-334867 (SB 334867A) is an excellent,selective and blood-brain barrier permeable orexin-1 (OX1) receptor antagonist, shows selectivity over OX2 (pKb=7.4), 100-fold over 5-HT2B, 5-HT2C with pKi values of 5.4 and 5.3, respectively. SB-334867 reduces ethanol consumption and inhibits the acquisition of morphine-induced sensitization to locomotor activity in vivo.

    Description

    SB-334867 (SB 334867A) is an excellent,selective and blood-brain barrier permeable orexin-1 (OX1) receptor antagonist, shows selectivity over OX2 (pKb=7.4), 100-fold over 5-HT2B, 5-HT2C with pKi values of 5.4 and 5.3, respectively[1]. SB-334867 reduces ethanol consumption and inhibits the acquisition of morphine-induced sensitization to locomotor activity in vivo[2][3].

    In Vitro

    SB-334867 (100 pM- 10 μM) inhibits the orexin-A (10 nM) and orexin-B (100 nM)-induced calcium responses in a concentration-dependent manner, with apparent pKb values of 7.27±0.04 and 7.23±0.03, but has no effect on the calcium response elicited by UTP (3 μM), which activates an endogenous purinergic receptor in CHO-OX1 and CHO-OX2 cells[4].

    In Vivo

    SB-334867 (intraperitoneal injection; 20 mg/kg; 20 days) administers 15 min before morphine injection can significantly decrease the effect of the morphine challenge dose in mice in comparison with the sporadically morphine-treated group[2].
    SB334867 (intraperitoneal injection; 3, 10 and 30 mg/kg) significantly reduces ethanol intake relative to vehicle and does not effect water consumption in female P rats[3].
    SB334867 (intraperitoneal injection; 3, 10 and 30 mg/kg) reduces ethanol consumption at the 30 mg/kg dose, high dose suppresses sucrose intake relative to vehicle, and it results in lower blood ethanol concentrations (BECs) relative to both the 10 and 30 mg/kg doses[3].

    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: ≥ 0.33 mg/mL (0.93 mM); Clear solution

      This protocol yields a clear solution of ≥ 0.33 mg/mL (saturation unknown).

      Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (3.3 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: ≥ 0.33 mg/mL (0.93 mM); Clear solution

      This protocol yields a clear solution of ≥ 0.33 mg/mL (saturation unknown).

      Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (3.3 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.
