Compound Overview
Spiperone, also known as Spiroperidol, is a potent antagonist of dopamine D2, serotonin 5-HT1A, and serotonin 5-HT2A receptors, and it also serves as a labelled ligand for neuroleptic receptors. It enhances intracellular calcium levels and inhibits the Wnt signaling pathway, giving it potential for neurology disease research[1][2][3][4]. It is supplied as an off-white to light yellow solid (C23H26FN3O2, MW 395.47) at 99.58% purity.

Safety
For Research Use Only. Not for use in diagnostic or therapeutic procedures, and not for human or veterinary use. Handle in accordance with the Safety Data Sheet and your institution's chemical hygiene plan.
In Vitro
| Solvent | Solubility | Notes |
|---|---|---|
| DMSO | 33.33 mg/mL (84.28 mM) | requires sonication and warming and heat to 60°C; use freshly opened DMSO (absorbed moisture lowers solubility) |
Aliquot the stock solution and store it at -80°C (up to 6 months) or -20°C (up to 1 month); avoid repeated freeze-thaw cycles.
In Vivo
Choose the formulation that suits the animal model and route of administration; percentages are volume ratios of the final working solution. Start from a clear DMSO stock (see In Vitro above), add the co-solvents one at a time in the order listed, mixing after each addition, and prepare the working solution fresh on the day of dosing. If precipitation or phase separation occurs, gentle warming or sonication can help.
Protocol 1
| Composition | 10% DMSO + 40% PEG300 + 5% Tween-80 + 45% saline |
|---|---|
| Result | ≥ 4.55 mg/mL (11.51 mM); clear solution |
| How to prepare | Gives a clear solution at ≥ 4.55 mg/mL (saturation not determined). For 1 mL of working solution: add 100 μL DMSO stock (45.5 mg/mL) to 400 μL PEG300; then 50 μL Tween-80; then 450 μL saline to bring the volume to 1 mL. Saline: dissolve 0.9 g sodium chloride in ddH2O and make up to 100 mL. |
Protocol 2
| Composition | 10% DMSO + 90% Corn Oil |
|---|---|
| Result | ≥ 2.5 mg/mL (6.32 mM); clear solution |
| How to prepare | Gives a clear solution at ≥ 2.5 mg/mL (saturation not determined). Use with caution if continuous dosing will exceed two weeks. For 1 mL of working solution: add 100 μL DMSO stock (25.0 mg/mL) to 900 μL corn oil. |

In Vitro
In HEK293 cells, Spiperone (5 μM, 24 h) selectively blocks Wnt signaling by acting on the Wnt/LRP complex[4]. Spiperone (1-10 μM, 275-470 s) raises intracellular calcium levels in HEK293 cells[4].
