    Product Description

    D-α-Hydroxyglutaric acid (D-2-HG) is an α-hydroxy acid.1 It decreases the oxygen consumption rate (OCR) and ratio of ATP to ADP in U87 glioma cells when used at a concentration of 800 µM. D-2-HG (100 µM) increases the levels of thiobarbituric acid reactive substances (TBARS) in isolated rat cerebral cortex homogenates.2 Urinary levels of D-2-HG are increased in D-2-hydroxyglutaric aciduria, a neurometabolic disease characterized by epilepsy, muscle hypotonia, and delays in psychomotor development.3,4 D-2-HG is structurally similar to α-ketoglutarate, the product of wild-type isocitrate dehydrogenases, and competitively inhibits α-ketoglutarate-dependent dioxygenases, including histone lysine demethylases and DNA hydroxylases.5,6,7
