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 (6.21 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 (6.21 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.

4. Then add μL
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
Membranes of neurotransmitter receptors are prepared from the tissues of rat, mouse, and guinea pig or from recombinant cells. These membranes are incubated in assay buffers containing selective radioligand for each receptor and AP521. After the incubation, the mixture is vacuum filtered through a glass membrane filter and washed by cold reaction buffer. Afterward, the radioactivity of the filters is counted[1].

Male Sprague-Dawley rats weighing 250 to 300 g are anesthetized with pentobarbital sodium (50 mg/kg, i.p.) and placed on a stereotaxic apparatus. Dialysis probes with an outer diameter of 0.105 mm are inserted into the guide cannulae so that 3.0 mm of the probes are exposed to the tissue of the medial prefrontal cortex. Rats are housed individually after these operations. On the following day, perfusion is started in the home cage using artificial cerebrospinal fluid (145 mM NaCl, 3.0 mM KCl, 1.3 mM CaCl2, 1.0 mM MgCl2) at a flow rate of 2 mL/min. AP521 (3, 10 mg/kg), tandospirone (10 mg/kg) or vehicle are administered subcutaneously 60 min after sample collection started. The dialysate samples are collected every 30 min for 180 min and extracellular levels of 5-HT are determined[1].
