Approved drug
mitapivat is an approved drug (EMA & FDA (2022))
Compound class: Synthetic organic
Comment: Mitapivat (AG-348) is a first-in-class, small molecule allosteric activator of the pyruvate kinases. It activates the PK isoform that is found in erythrocytes (PKR protein that is expressed from the PKLR gene) and the embryonic PKM2 isoform (expressed from the PKM gene) that is only expressed by cancer cells in adult tissues. Mitapivat was developed by Agios Pharmaceuticals as a novel therapy for diseases of red blood cells that are associated with inherited PKR deficiency [2], and for potential in cancer therapy via activation of PKM2. Activation of PK in red cells increases hemoglobin levels [4-5]. The active drug is the sulfate hydrate (PubChem CID 134693700). We show the structure for the parent molecule as described by its INN.
