Alogabat
Based on 1 Customer Validation
Alogabat is a positive allosteric modulator (PAM) and agonist (Ki <100 nM) of the GABAA α5 receptor, targeting the α5β3γ2 subunit with a Ki of 8.7 nM. Alogabat increases the expression level of α5β3γ2 in oocytes (1.97-fold). GABAA has been implicated in cognitive impairment associated with central nervous system (CNS) disorders, brain cancer (including brain tumors such as medulloblastoma), and can be used in the study of mild cognitive impairment (MCI), amnestic MCI (aMCI), age-associated memory impairment (AAMI), age-related cognitive decline (ARCD), dementia, Alzheimer's disease (AD), prodromal AD, post-traumatic stress disorder (PTSD), schizophrenia, bipolar disorder, amyotrophic lateral sclerosis (ALS), cognitive impairment associated with cancer treatment, mental retardation, Parkinson's disease (PD), autism spectrum disorder, fragile X, Rett syndrome, obsessive-compulsive behavior, and substance addiction.

Biological Activity
|
GABA α5β3γ2 receptor |
Alogabat (compound 8) binds selectively to the α5 subunit over α1, α2, and α3. The Ki in HEK293 cells is 8.7 nM (hGABA-Aα5β3γ2)[1].
Alogabat (30×Ki=261 nM, transient) potently enhances GABA-evoked currents in oocytes with an efficiency of 97% to elicit 20% of the maximal current response (EC20)[1].

Solvent & Solubility
DMSO : 33.33 mg/mL (81.40 mM; Need ultrasonic; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
Please refer to the solubility information to select the appropriate solvent. Once prepared, please aliquot and store the solution to prevent product inactivation from repeated freeze-thaw cycles.
Storage method and period of stock solution: -80°C, 6 months; -20°C, 1 month. When stored at -80°C, please use it within 6 months. When stored at -20°C, please use it within 1 month.

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.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 2.5 mg/mL (6.11 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 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.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 2.5 mg/mL (6.11 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 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.
