Catecholamines, dopamine, norepinephrine, and epinephrine are chemical neurotransmitters and hormones that regulate physiological processes as well as the onset and progression of neurological, psychiatric, endocrine, and cardiovascular illnesses [1]. The catecholamines, which include dopamine (3,4-dihydrophenylethylamine), norepinephrine (norepinephrine), and epinephrine (epinephrine), function as neurotransmitters or hormones both centrally and peripherally. Dopamine, the most prevalent monoamine neurotransmitter, is also found in non-neuronal tissues such as the gastrointestinal system and kidneys, where it regulates sodium balance [2].

| Additional Infomation |
Vanilpyruvic acid is a 2-oxo monocarboxylic acid that is 3,4-dihydroxyphenylpyruvic acid in which the hydroxy group at position 3 is substituted by a methoxy group. It has a role as a human urinary metabolite. It is a 2-oxo monocarboxylic acid, a monomethoxybenzene and a member of phenols. It is functionally related to a 3,4-dihydroxyphenylpyruvic acid. It is a conjugate acid of a vanilpyruvate.

| Solubility (In Vitro) |

| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.08 mg/mL (9.90 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 20.8 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: 2.08 mg/mL (9.90 mM) in 10% DMSO + 90% (20% SBE-β-CD in Saline) (add these co-solvents sequentially from left to right, and one by one), suspension solution; with ultrasonication. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 20.8 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. (Please use freshly prepared in vivo formulations for optimal results.) |

*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.
Calculation results
Working concentration： mg/mL；
Method for preparing DMSO stock solution： mg drug pre-dissolved in μL DMSO (stock solution concentration mg/mL). Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug.
Method for preparing in vivo formulation:：Take μL DMSO stock solution, next add μL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O，mix and clarify.
(1) Please be sure that the solution is clear before the addition of next solvent. Dissolution methods like vortex, ultrasound or warming and heat may be used to aid dissolving.
(2) Be sure to add the solvent(s) in order.
