Reduction of oxoglutarate (2OG or alpha-ketoglutarate) to 2-hydroxyglutarate (2HG) is driven by NADPH. 2HG is also formed in side reactions of lactate dehydrogenase and malate dehydrogenase. Millimolar 2HG concentrations are found in some cancer cells compared to , whereas side activities of lactate and malate dehydrogenase form submillimolar s-2-hydroxyglutarate (s-2HG). However, even wild-type IDH1 and IDH2, notably under shifts toward reductive carboxylation glutaminolysis or changes in other enzymes, lead to β€œintermediate” 0.01–0.1 mM 2HG levels, for example, in breast carcinoma compared with nanomolar concentrations in benign cells. 2HG is considered an important player in reprogramming metabolism of cancer cells.
