Aminooxyacetic acid is a GABA transaminase (GABA-T) inhibitor (Ki = 9.16 μM) that induces GABA accumulation in the brain.1 It also inhibits cystathionine β synthase (CBS) and cystathionine γ lyase (CSE; IC50s = 8.5 and 1.1 μM, respectively).2 Aminooxyacetic acid (100 mg/kg) decreases GABA-T activity, without affecting glutamic acid decarboxylase (GAD) activity, and increases GABA levels in all regions of rat brain.3 It also decreases GABA-T activity and increases GABA in mouse brain when administered at a dose of 13 mg/kg.4 Aminooxyacetic acid inhibits 3-mercaptopropionic acid-, strychnine-, and pentetrazole-induced seizures in mice (ED50s = 53, 130, and 85 mg/kg, respectively), however, it exhibits neurotoxicity in the chimney test (ED50 = 62 mg/kg) and is lethal (LD50 = 105 mg/kg) to mice.

Step 2: Enter the in vivo formulation (This is only the calculator, not formulation. Please contact us first if there is no in vivo formulation at the solubility Section.)

% DMSO % % Tween 80 % ddH2O

Calculation results:

Working concentration: mg/ml;

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid 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 master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such as vortex, ultrasound or hot water bath can be used to aid dissolving.
3. All of the above co-solvents are available for purchase on the GlpBio website.
