Product Description
Aminooxyacetic acid (Carboxymethoxylamine) hemiHCl is a malate-aspartate shuttle (MAS) inhibitor and can also inhibit the GABA-degrading enzyme GABA-T.
Biological Activity I Assay Protocols (From Reference)
ln Vitro
Aminoxyacetic acid hemihydrochloride (AOAA) dose-dependently decreases the stroma of C6 neuroastrocytoma cells. Treatment with aminooxyacetic acid hemihydrochloride greatly raised the proportion of cells in the G0/G1 phase of the cervix, and dramatically lowered the proportion of cells in the purified AS phase and G2/M phase. Treatment with hemihydrochloride resulted in a considerable reduction in the number of cells in the cell division phase. Aminoacetic acid hemihydrochloride considerably raised the percentage of early cells and surviving cells. Treatment of cells with 1 mM or 5 mM aminooxyacetic acid hemihydrochloride lowers cell senescence [1]. Glutamine-dependent cell lines revealed a stronger inhibitory effect on cell development by ammonia oxygen hemihydrochloride (AOA) than glutamine-dependent cells [3].
ln Vivo
GABA accumulates in the cerebellum and throughout the brain fairly quickly at first; five minutes after ethylene oxide hemihydrochloride (AOAA) injection, there is a noticeable increase in GABA levels. After 2 to 6 hours of ethylene oxide hemihydrochloride, the rapid final accumulation gradually slows down and achieves maximum levels (400 to 600% of control levels). Within twenty-four hours, GABA levels rose by about 250%. The amount of GABA increases by about 250% after 2–6 hours. the seizures were stopped. The 24-hour withdrawal of ammonia hemihydrochloride is identical to that which is required for expectant mothers [2].

Additional Infomation
(aminooxy)acetic acid hemihydrochloride is the hemihydrochloride salt of (aminooxy)acetic acid. It is a malate-aspartate shuttle (MAS) inhibitor which also inhibits the GABA degradating enzyme 4-aminobutyrate aminotransferase and cystathionine beta-synthetase. It contains an (aminooxy)acetate.

Solubility Data
Solubility (In Vitro)
DMSO : ~125 mg/mL (~1143.64 mM)
H2O : ~100 mg/mL (~914.91 mM)
Solubility (In Vivo)
Solubility in Formulation 1: ≥ 2.08 mg/mL (19.03 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 (19.03 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 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.

*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.

Calculator

Molarity Calculator allows you to calculate the mass, volume, and/or concentration required for a solution, as detailed below:

  • Calculate the Mass of a compound required to prepare a solution of known volume and concentration
  • Calculate the Volume of solution required to dissolve a compound of known mass to a desired concentration
  • Calculate the Concentration of a solution resulting from a known mass of compound in a specific volume
An example of molarity calculation using the molarity calculator is shown below:
What is the mass of compound required to make a 10 mM stock solution in 5 ml of DMSO given that the molecular weight of the compound is 350.26 g/mol?
  • Enter 350.26 in the Molecular Weight (MW) box
  • Enter 10 in the Concentration box and choose the correct unit (mM)
  • Enter 5 in the Volume box and choose the correct unit (mL)
  • Click the “Calculate” button
  • The answer of 17.513 mg appears in the Mass box. In a similar way, you may calculate the volume and concentration.

Dilution Calculator allows you to calculate how to dilute a stock solution of known concentrations. For example, you may Enter C1, C2 & V2 to calculate V1, as detailed below:

What volume of a given 10 mM stock solution is required to make 25 ml of a 25 μM solution?
Using the equation C1V1 = C2V2, where C1=10 mM, C2=25 μM, V2=25 ml and V1 is the unknown:
  • Enter 10 into the Concentration (Start) box and choose the correct unit (mM)
  • Enter 25 into the Concentration (End) box and select the correct unit (mM)
  • Enter 25 into the Volume (End) box and choose the correct unit (mL)
  • Click the “Calculate” button
  • The answer of 62.5 μL (0.1 ml) appears in the Volume (Start) box
