AWD 131-138 is a partial agonist of benzodiazepine receptor [1].
Benzodiazepine (BZD) is a psychoactive drug and acts as positive allosteric modulators of the inhibitory neurotransmitter GABA by binding to a recognition site (BZD receptor) of the GABAA receptor chloride ionophore complex [1].
AWD 131-138 is a partial benzodiazepine receptor agonist with anticonvulsant and anxiolytic activity [1]. In Xenopus oocytes expressed recombinant γ-aminobutyric acid A (GABAA) receptors of ɑ1β2γ2, ɑ1β3γ2, ɑ2β2γ2, ɑ3β2γ2 and ɑ5β2γ2, AWD 131-138 stimulated GABA currents in a dose-dependent way and acts at the binding site for benzodiazepines. AWD 131-138 (10 μM) stimulated GABA currents up to 12-21% of the maximal stimulation achieved by diazepam [2].
In a dog seizure model, AWD 131-138 increased the pentylenetetrazole (PTZ) seizure threshold. AWD 131-138 (5 or 40 mg/kg) caused relatively mild abstinence symptoms, particularly at the lower dosage. In dogs with newly diagnosed epilepsy, AWD 131-138 significantly reduced seizure frequency and severity [3].

General tips | Please select the appropriate solvent to prepare the stock solution according to the solubility of the product in different solvents; once the solution is prepared, please store it in separate packages to avoid product failure caused by repeated freezing and thawing.Storage method and period of the stock solution: When stored at -80°C, please use it within 6 months; when stored at -20°C, please use it within 1 month. To increase solubility, heat the tube to 37°C and then oscillate in an ultrasonic bath for some time. |

Step 1: Enter information below (Recommended: An additional animal making an allowance for loss during the experiment)
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.)
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.
