Solvent & Solubility
DMSO : 16.67 mg/mL (39.65 mM; Need ultrasonic; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
Please refer to the solubility information to select the appropriate solvent. Once prepared, please aliquot and store the solution to prevent product inactivation from repeated freeze-thaw cycles.
Storage method and period of stock solution: -80°C, 2 years; -20°C, 1 year. When stored at -80°C, please use it within 2 years. When stored at -20°C, please use it within 1 year.

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: ≥ 1.67 mg/mL (3.97 mM); Clear solution
This protocol yields a clear solution of ≥ 1.67 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (16.7 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: 1.67 mg/mL (3.97 mM); Suspended solution; Need ultrasonic
This protocol yields a suspended solution of 1.67 mg/mL. Suspended solution can be used for oral and intraperitoneal injection.
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (16.7 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.

Please ensure that the stock solution in the first step is dissolved to a clear state, and add co-solvents in sequence. You can use ultrasonic heating (ultrasonic cleaner, recommended frequency 20-40 kHz), vortexing, etc. to assist dissolution.
Protocol
The membranes are prepared from frozen HA7 cells. Cells are harvested in ice-cold Tris-HCl pH 7.4, homogenized and centrifuged at 40 000×g, 4°C for 10 min. The pellet is suspended in the same buffer and centrifuged again. After the second centrifugation, the pellet is suspended in an assay buffer consisting of pargyline (10 μM) and CaCl2 (4 mM) in Tris-HCl (50 mM, pH 7.4). Membrane protein, 0.031-0.084 mg/tube, is incubated with [3H] 8-OH-DPAT (1 nM final concentration) and Ocaperidone at seven concentrations, for 30 min, room temperature. The reaction is terminated by filtration through Whatman filters, and radioactivity is counted by liquid scintillation spectrometry. The experiments are performed in triplicate. Data are analyzed using the non-linear curve fitting program EBDA/LIGAND. Results expressed as pKi values are means of three determinations[3].

Rats[1]
Male Wistar rats (200 g) are treated subcutaneously with various dosages (0.01-10 or 2.5-40 mg/kg) of Ocaperidone dissolved in saline (injection of 1 mL of drug solution/100 g of body weight) or with saline (control); 1 hr thereafter the rats receive 1 μg/kg (5-10 μCi) [3H]spiperone by intravenous injection in the tail vein. The rats are sacrificed by decapitation 1 hr after the [3H]spiperone injection; the striatum, the nucleus accumbens, the tuberculum olfactorium, the frontal cortex, and the cerebellum are immediately dissected. The tissues are cooled on ice, weighed, and dissolved in 10 mL of Instagel II, in plastic counting vials. After 48 hr the radioactivity is counted; data are expressed in dpm, using external standard counting and referring to a quenched standard curve. The counted radioactivity is converted to pg of [3H]spiperone/mg of tissue. Four to six animals are treated at each drug dosage. For each drug and brain area, the values are averaged and graphically plotted versus the logarithm of the drug dosages. On each graph, values measured in the cerebellum are plotted; labeling in the cerebellum is taken as an indication of nonspecific tissue labeling[1].
