YM348 has high affinity for cloned human 5-HT2C receptors with a Ki value of 0.89 nM and lower affinities for human-cloned 5-HT2B (Ki: 2.5 nM) and 5-HT2A receptors (Ki: 13 nM). To assess the binding specificity of YM348, a broad evaluation of an additional 46 binding sites including several other 5-HT receptor subtypes (1A, 1B, 1D, 3, 4, 5A, 6, 7) is performed. IC50 values of YM348 are found to be >1 μM for all of the binding sites except for the human 5-HT1A receptors (Ki: 130 nM), bovine 5-HT1D receptors (Ki: 481 nM), human 5-HT7 receptors (Ki: 177 nM), and human α2A receptors (Ki: 126 nM).YM348 exhibits a full-agonistic activity on human 5-HT2A and 5-HT2B receptors. The EC50 values of YM348 for 5-HT2C, 5-HT2A, and 5-HT2B receptors are 1.0, 93 and 3.2 nM, respectively[1].

Solvent & Solubility
DMSO : 100 mg/mL (411.02 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, 6 months; -20°C, 1 month (sealed storage, away from moisture and light). 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 (10.28 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.

Protocol
Experiments are performed with membranes obtained from Chinese Hamster Ovary (CHO) cells expressing human 5-HT2C or 5-HT2A receptors and Human Embryonic Kidney 293-Epstein-Barr virus nuclear antigen (HEK293-EBNA) cells expressing human 5-HT2B receptors. Binding assays with [3H] 5-HT are carried out. The reaction medium (50 mM Tris-HCl buffer (pH 7.4) containing 4 mM CaCl2, 10 M pargyline and 0.1 mg/ml L-(+)-ascorbic acid) containing [3H] 5-HT, membrane preparation and test compounds are incubated at 37°C for 30 min. Nonspecific binding is determined in the presence of 10 M 5-HT, and specific binding is calculated as the total binding minus the nonspecific binding. After incubation, 4 mL of 50 mM Tris-HCl buffer (pH 7.4) containing 4 mM CaCl2 is added, and the medium is filtrated under decompression through a Whatman GF/B glass filter pretreated with 0.1% polyethyleneimine. The filter is washed with the same buffer solution (4 mL×3). The glass filter is immersed in 6 mL of liquid scintillator (Packard, Aquasol-2), and the radioactivity is measured with a liquid scintillation counter. The amount of protein is measured. The dissociation constants (Kd values) are obtained by Scatchard analysis using SAS (ver. 6.11). The concentrations of compounds showing 50% inhibition of receptor binding, IC50 values, are obtained by nonlinear analysis using SAS (ver. 6.11). The Ki values indicating affinity for receptors are calculated[1].

Rats[1]
Male Wistar rats (215-350 g) are used. Rats are administered YM348 (0.0677, 0.203, 0.677, and 2.03 mg/kg) orally and moved again to their home cages. After 20 min, thereafter, the rats are individually placed in transparent acrylic plastic cages (35×30×18 cm), and their motor activity is measured for 40 min. The measurements are carried out using a SUPER-MEX sensor. SB242084 (0.1-3 mg/kg i.p.) is administered 30 min before YM348 treatment.
