Egalognastat
Based on 1 Customer Validation
Egalognastat (ASN90) is a selective, brain-penetrant and orally active O-GlcNAcase (OGA) enzyme inhibitor with an IC50 value of 10.2 nM. Egalognastat increases O-GlcNAcylation of intracellular proteins like tau and α-synuclein, preventing their aggregation and toxicity. Egalognastat does not inhibit hexosaminidase (Hex). Egalognastat can be used for the research of neurodegenerative diseases, such as tauopathies and α-synucleinopathies (e.g., Alzheimer’s disease and Parkinson’s disease).

Biological Activity
Egalognastat (ASN90) inhbibits O-GlcNAcase (OGA) by substrate competition and reversible binding[1].
Egalognastat induces protein O-GlcNAcylation in plated human and rodent PBMC with EC50 values of 209 nM and 489 nM, respectively[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
Egalognastat (30-100 mg/kg; oral administration; once a day; administered for 3.5 months) reduces pathological tau protein in the cerebral cortex and hippocampus and alleviates neurofibrillary tangle-like pathology in P301S tau transgenic mice[1].
Egalognastat (30-100 mg/kg; oral administration; once a day; administered for 4 days) improves upper airway dysfunction in 7-month-old P301L tau transgenic mice[1].
Egalognastat (30-100 mg/kg; oral administration; once a day; administered for 6 months) improves motor behavior and increases survival rate in 3.5-month-old P301L tau transgenic mice[1].
Egalognastat (30-100 mg/kg; oral administration; once a day; administered for 24 weeks) improves motor function, reduces astrogliosis, and promotes O-GlcNAcylation of α-synuclein in Line 61 α-synuclein transgenic mice.

-
Animal Model:Male Line 61 α-synuclein transgenic mice (1 month of age), overexpress human α-synuclein throughout the brain under the Thy1 promoter[1].
-
Dosage:30 mg/kg and 100 mg/kg
-
Administration:Oral gavage, once a day, 24 weeks

Solvent & Solubility
DMSO : 100 mg/mL (266.35 mM; ultrasonic and warming and heat to 80°C; 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 (6.66 mM); Clear solution; Need ultrasonic
This protocol yields a clear solution of 2.5 mg/mL.
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.
