SB-674042 ([3H]) (0.2-24 nM; 2 h) shows high-affinity and serves as a radio ligand suitable for labelling human OX1 receptors stably expressed in CHO cells[1].
SB-674042 (5 μM; 4 °C for 30 min, and 37 °C for 3 h) reduces the potency of CB1 receptor agonist (HY-14137) to phosphorylate ERK1/2 in HEK293 cells co-expressing the orexin-1 and CB1 receptors[2].
SB-674042 (1 μM; 24 h) eradicates the increase in mTOR phosphorylation in response to Orexin-A (HY-106224) (1 nM-1 μM; 24 h) in INS-1 cells, indicating activation of the mTOR pathway induced by orexin-A was dependent on the activated OX1 receptor[3].

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.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 1.43 mg/mL (3.19 mM); Clear solution
This protocol yields a clear solution of ≥ 1.43 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (14.3 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.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 1.43 mg/mL (3.19 mM); Clear solution
This protocol yields a clear solution of ≥ 1.43 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (14.3 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.
