D-α-Hydroxyglutaric acid disodium (Disodium (R)-2-hydroxyglutarate) is the principal metabolite accumulating in neurometabolic disease D-2-hydroxyglutaric aciduria. D-α-Hydroxyglutaric acid disodium is a weak competitive antagonist of α-ketoglutarate (α-KG) and inhibits multiple α-KG-dependent dioxygenases with a K_i of 10.87 mM. D-α-Hydroxyglutaric acid disodium increases reactive oxygen species (ROS) production. D-α-Hydroxyglutaric acid disodium binds and inhibits ATP synthase and inhibits mTOR signaling^{[1][2][3][4][5]}.

D-α-Hydroxyglutaric acid ((R)-2-hydroxyglutarate) accumulates in human cancers carrying neomorphic mutations in the isocitrate dehydrogenase (IDH) 1 and 2 genes^[1][2].
A partial inhibition of KDM7A toward both H3K9me2 and H3K27me2 peptides is observed in the presence of 50 mM D-2-HG and 100 μM α-ketoglutarate (α-KG). Addition of 300 μM α-KG is capable of reversing the inhibition of Caenorhabditis elegans KDM7A (CeKDM7A) by 50 mM D-2-HG, indicating that D-2-HG is a weak competitive inhibitor against α-KG toward the CeKDM7A demethylase^[1].
D-α-Hydroxyglutaric acid is a weak inhibitor of TET hydroxylases. In the presence of 0.1 mM of α-KG, addition of 10 mM D-α-Hydroxyglutaric acid results in a partial (33%) inhibition of TET2 and addition of 50 mM D-α-Hydroxyglutaric acid results in more inhibition (83%) of TET2. D-α-Hydroxyglutaric acid exhibits a less pronounced inhibitory effect toward TET1^[1].

D-α-Hydroxyglutaric acid strongly inhibits glucose utilization, CO₂ production and the respiratory chain in rat cerebral cortex and human skeletal muscle, as well as in submitochondrial particles from bovine heart, suggesting an impairment of the aerobic metabolism^[5].
D-α-Hydroxyglutaric acid has also been proposed as an endogenous excitotoxic organic acid because it significantly decreased cell viability in neuronal cultures from chick embryo telencephalons and from neonatal rat hippocampus through stimulation of specific NMDA glutamate receptors^[5].
D-α-Hydroxyglutaric acid (0.01-1 mM) significantly increases chemiluminescence and thiobarbituric acid-reactive substances (TBA-RS) and decreased total antioxidant reactivity (TAR) values in the cortical supernatants in 30-day-old-rats^[5].

U87 cells, HCT 116 IDH1(R132H/+) cells, and HEK 293 cells are seeded in 12-well plates and after overnight incubation are treated with indicated concentrations of each compound (e.g., 400 and 800 μM D-α-Hydroxyglutaric acid). After harvesting, cells are stained with Acridine Orange (AO) and DAPI. Cell number and viability are measured based on AO and DAPI fluorescence measured by NC3000^[2].

L-2-Hydroxyglutaric acid disodium is an epigenetic modifier and putative oncometabolite in renal cancer. L-2-Hydroxyglutaric acid disodium can inhibit histone demethylases and hence promote histone methylation^[1]. L-2-Hydroxyglutaric acid inhibits mitochondrial creatine kinase (Mi-CK) activity with K_m and K_i of 2.52 mM and 11.13 mM, respectively^[2].

L-2-Hydroxyglutaric acid is potent at inhibiting 2-oxoglutarate (2-OG) dependent dioxygenases (2OGDs) including the Ten Eleven Translocation (TET) enzymes^[1].
