(Rac)-WAY-161503 (3-30 mg/kg; intraperitoneal injection; male C57BL/6J mice) reduces locomotor activity in a dose-dependent manner; the 5-HT2C/2B antagonist SER-082 blocks this effect[1].

| Animal Protocol |
Animal/Disease Models: Male C57BL/6J mice Hallucinogen 1-(2,5-dimethoxy-4-iodophenyl)-2-aminopropane (DOI) [1]
Doses: 3mg/kg, 10mg/kg, 30. mg/kg Route of Administration: intraperitoneal (ip) injection Experimental Results: Locomotor activity was diminished in a dose-dependent manner, and this effect could be blocked by the 5-HT2C/2B antagonist SER-082. WAY 161,503 was dissolved in saline containing 2.5% Tween 80. DOI and WAY 161,503 were administered intraperitoneally at a volume of 5 ml/kg body weight. [1] Animals were placed in the mouse BPM chambers 15 min after treatment with DOI, or 10 min after treatment with WAY 161,503. In experiment 1, mice (n=10–11, 63 total) were treated with vehicle, 0.625, 1.25, 2.5, 5.0, or 10 mg/kg DOI. In experiment 2, the 5-HT2A cohort consisted of 14 WT and 13 KO male mice, and 13 WT and 5 KO female mice. The mice were tested in a three-way crossover design with 1 week between tests. Each animal received vehicle as well as 1.0 and 10 mg/kg DOI in a semi-randomized, counterbalanced order, to complete a within-subject design. In experiment 3, mice (n=10, 60 total) were treated with SER-082 (vehicle or 1.0 mg/kg) 15 min before administration of DOI (vehicle, 1.0, or 10 mg/kg). In experiment 4, mice (n=8–10, 38 total) were treated with vehicle or 3, 10, or 30 mg/kg WAY 161,503. In experiment 5, mice (n=8–10, 38 total) were treated with SER-082 (vehicle or 1.0 mg/kg) 20 min before administration of WAY 161,503 (vehicle, 1, or 10 mg/kg). In experiment 6, a new 5-HT2A cohort consisted of 8 WT and 10 KO male mice, and 9 WT and 11 KO female mice. WT and KO mice were injected with either vehicle or WAY 161,503 (10 mg/kg) in a between subjects design.[1] |

| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.5 mg/mL (9.19 mM) (saturation unknown) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL. Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution. Solubility in Formulation 2: ≥ 2.5 mg/mL (9.19 mM) (saturation unknown) in 10% DMSO + 90% (20% SBE-β-CD in Saline) (add these co-solvents sequentially from left to right, and one by one), clear solution. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 900 μL of 20% SBE-β-CD physiological saline solution and mix evenly. Preparation of 20% SBE-β-CD in Saline (4°C，1 week): Dissolve 2 g SBE-β-CD in 10 mL saline to obtain a clear solution. View More

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
