    Description

    Aminooxyacetic acid (Carboxymethoxylamine) hemihydrochloride is a malate-aspartate shuttle (MAS) inhibitor which also inhibits the GABA degradating enzyme GABA-T.

    IC50 & Target

    MAS[1], GABA-T[2]

    In Vitro

    Aminooxyacetic acid hemihydrochloride (AOAA) dose-dependently decreases the survival of C6 glioma cells. Aminooxyacetic acid hemihydrochloride treatment produces a significant increase in the percentage of the cells arrested in the stage of G0/G1, as well as a significant decrease in the percentage of the cells at S phase and G2/M phase. Aminooxyacetic acid hemihydrochloride treatment leads to an obvious decrease in the number of the cells in the phase of cell division. Aminooxyacetic acid hemihydrochloride significantly increases the percentage of the cells in both early-stage apoptosis and necrosis. Treatment of the cells with 1 mM or 5 mM Aminooxyacetic acid hemihydrochloride leads to decreased levels of aging of the cells[1]. Glutamine-dependent cell lines show greater inhibition of cell growth by Aminooxyacetic acid hemihydrochloride (AOA) compare with cells that are less glutamine dependent[3].

    In Vivo

    The accumulation of GABA in cerebellum and whole brain is initially very rapid, being significantly increased already 5 min after the injection of Aminooxyacetic acid hemihydrochloride (AOAA). The rapid initial accumulation becomes gradually slower and maximal levels (400 to 600 % of the control levels) are reached 2 to 6 h after Aminooxyacetic acid hemihydrochloride. Still 24 h after Aminooxyacetic acid hemihydrochloride the GABA levels are elevated by about 250%. From 2 to 6 h after Aminooxyacetic acid hemihydrochloride the convulsions are completely blocked. Twenty four hours after Aminooxyacetic acid hemihydrochloride the convulsions are almost identical to the controls[2].

    In Vivo:

    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.

    • Protocol 1

      Add each solvent one by one:  10% DMSO    40% PEG300    5% Tween-80    45% Saline

      Solubility: ≥ 2.08 mg/mL (19.03 mM); Clear solution

      This protocol yields a clear solution of ≥ 2.08 mg/mL (saturation unknown).

      Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.8 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 2

      Add each solvent one by one:  10% DMSO    90% (20% SBE-β-CD in Saline)

      Solubility: ≥ 2.08 mg/mL (19.03 mM); Clear solution

      This protocol yields a clear solution of ≥ 2.08 mg/mL (saturation unknown).

      Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.8 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.

      Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.

    For the following dissolution methods, please prepare the working solution directly. It is recommended to prepare fresh solutions and use them promptly within a short period of time.
    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.

    Kinase Assay
    [3]

    Enzyme activity of aspartate transaminase is measured by a colorimetric assay assessing formation of pyruvate from oxaloacetate, a product of GOT1/2 (also called AST1/2) activity, as described previously. In brief, cells grown in 6-well plates are collected after 6, 24, or 48 hours of Aminooxyacetic acid hemihydrochloride (AOA) treatment and washed with cold PBS, lysed, and supernatant used for analysis[3].

    Cell Assay
    [3]

    Breast cancer cell lines are used in this study. Cells are plated in 96-well plates at 1,500 to 5,000 cells per well in 100 μL media. New medium with varying concentration of Aminooxyacetic acid hemihydrochloride (AOA) is added after 12 hours. The assay is performed after 48 hours[3].

    Animal Administration
    [2]

    Female albino rats (150 to 200 g) bred at our department are used. Aminooxyacetic acid hemihydrochloride (AOAA) is injected into a tail vein (2 mL/kg body weight). For this purpose the rat is placed in a plastic tube and the tail warmed in water 42°C[2].

    • Do most proteins show cross-species activity?

      Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
