VA012 (compound 11) is a positive allosteric modulator (PAM) of the serotonin 5-HT2C receptor. VA012 can reduce food intake and body weight gain during subchronic administration without causing central nervous system-related discomfort. VA012 can be used in obesity research.

Solubility Data

Solubility (In Vitro)

DMSO : ~100 mg/mL (~319.08 mM; with ultrasonication (<60°C))

Solubility (In Vivo)

Solubility in Formulation 1: ≥ 2.5 mg/mL (7.98 mM) (saturation unknown) in 10% DMSO +40% PEG300 +5% Tween-80 +45% Saline (add these co-solvents sequentially from left to right, and one by one), clear solution。 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 (7.98 mM) (saturation unknown) in 10% DMSO +90% Corn Oil (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 the 25.0 mg/mL clear DMSO stock solution to 900 μL corn oil and mix well.  (Please use freshly prepared in vivo formulations for optimal results.)

Preparing Stock Solutions		1 mg	5 mg	10 mg
	1 mM	3.1908 mL	15.9541 mL	31.9081 mL
	5 mM	0.6382 mL	3.1908 mL	6.3816 mL
	10 mM	0.3191 mL	1.5954 mL	3.1908 mL

*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.
