Mitapivat
Based on 3 publication(s) in Google Scholar
Mitapivat (AG-348) is an orally active pyruvate kinase allosteric activator. Mitapivat increases enzymatic activity, protein stability, and ATP levels over a broad range of PKLR genotypes, shows the potential to restore the activity of PK (pyruvate kinase)-deficient glycolytic pathways. Mitapivat can be used in study of PK deficiency.

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 (5.55 mM); Suspended solution; Need ultrasonic
This protocol yields a suspended solution of 2.5 mg/mL. Suspended solution can be used for oral and intraperitoneal injection.
