Solvent & Solubility
DMSO : 100 mg/mL (214.31 mM; Need ultrasonic; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
Ethanol : 50 mg/mL (107.15 mM; Need ultrasonic)
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, 6 months; -20°C, 1 month. When stored at -80°C, please use it within 6 months. When stored at -20°C, please use it within 1 month.

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: ≥ 2.5 mg/mL (5.36 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 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.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 2.5 mg/mL (5.36 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 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.

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
Binding of [3H]-LSD at rat cloned 5-HT7 receptor is performed in the assay. In 1 mL of incubation buffer (50 mM Tris, 10 mM MgCl2 and 0.5 mM EDTA, pH 7.4) are suspended 30 μg of membranes, 2.5 nM [3H]-LSD, LP-211 (6−9 concentrations). The samples are incubated for 60 min at 37°C. The incubation is stopped by rapid filtration on GF/A glass fiber filters (presoaked in 0.5% polyethylenimine for 30 min). The filters are washed with 3 × 53 mL of ice-cold buffer (50 mM Tris, pH 7.4). Nonspecific binding is determined in the presence of 10 μM 5-CT. Approximately 90% of specific binding is determined under these conditions[1].

Rats[3]
Thirty male adult Wistar rats (300-450 g) are assessed for novelty preference behavior after acute treatment (administered immediately after the training session and 24 h before the test session). After a 4 weeks' wash out, the rPDT is conducted to evaluate attraction from a greater/uncertain reward, with a sub-chronic treatment (five injections, immediately after sessions which follow the indifferent point). Food restriction, imposed by the experimenter through a limited quantity of food given at the end of each rPDT session, is applied to increase motivation to work for food delivery. All behavioral tests take place between 9:30 am and 4:00 pm. Rats are randomly assigned to treatment (LP-211 at 0.25 or 0.50 mg/kg i.p.) and control groups (injection volume 10 mL/kg; n = 10 per group). The brain penetrant 5-HT7R agonist LP-211 is dissolved in a vehicle solution of 1% dimethyl sulfoxide (DMSO) in saline (0.9% NaCl). Control group receives the vehicle strictly in the same conditions[3].
