Toxicity/Toxicokinetics |
Toxicity Summary
2-hydroxyglutarate is an oncometabolite. It is a competitive inhibitor of multiple α-ketoglutarate-dependent dioxygenases, including histone demethylases and the TET family of 5-methlycytosine (5mC) hydroxylases. As a result, high levels of 2-hydroxyglutarate lead to genome-wide histone and DNA methylation alterations, which in turn lead to mutations that ultimately cause cancer. L-2-hydroxyglutarate mediates its neurotoxicity through activation of N-methyl-D-aspartate receptors. L-2-hydroxyglutarate is structurally similar to the excitatory amino acid glutamate and stimulates neurodegeneration by mechanisms well-known for glutamate, NMDA or mitochondrial toxins (A15198). |

Additional Infomation |
(S)-2-hydroxyglutaric acid is a 2-hydroxyglutaric acid. It is a conjugate acid of a (S)-2-hydroxyglutarate(2-). It is an enantiomer of a (R)-2-hydroxyglutaric acid.
L-2-Hydroxyglutaric acid is a metabolite found in or produced by Escherichia coli (strain K12, MG1655). (2S)-2-hydroxypentanedioic acid has been reported in Homo sapiens and Caenorhabditis elegans with data available. L-2-Hydroxyglutaric acid is an alpha hydroxy acid. In humans the compound is formed by a hydroxyacid-oxoacid transhydrogenase whereas in bacteria is formed by a 2-hydroxyglutarate synthase. The compound can be converted to α-ketoglutaric acid through the action of a 2-hydroxyglutarate dehydrogenase. In humans, there are two such enzymes called D2HGDH and L2HGDH. Tissue accumulation of high amounts of D-2-hydroxyglutaric acid is the biochemical hallmark of the inherited neurometabolic disorder D-2-hydroxyglutaric aciduria. Both the D and the L stereoisomers of hydroxyglutaric acid (EC 1.1.99.2) are found in body fluids. Accumulation of L-2-hydroxyglutaric acid has been reported in multiple patients who have a clinical phenotype of progressive neurodegeneration with extrapyramidal and cerebellar signs, seizures, and spongiform changes in the white matter. Patients who have excess accumulation of D-2-hydroxyglutaric acid in the urine exhibit a variable phenotype but included mental retardation, macrocephaly with cerebral atrophy, hypotonia, seizures, and involuntary movements. |

Solubility (In Vivo) |
Note: Listed below are some common formulations that may be used to formulate products with low water solubility (e.g. < 1 mg/mL), you may test these formulations using a minute amount of products to avoid loss of samples.
Injection Formulations
Injection Formulation 1: DMSO : Tween 80: Saline = 10 : 5 : 85 (i.e. 100 μL DMSO stock solution → 50 μL Tween 80 → 850 μL Saline)(e.g. IP/IV/IM/SC) *Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH ₂ O to obtain a clear solution. Injection Formulation 2: DMSO : PEG300 :Tween 80 : Saline = 10 : 40 : 5 : 45 (i.e. 100 μL DMSO → 400 μLPEG300 → 50 μL Tween 80 → 450 μL Saline) Injection Formulation 3: DMSO : Corn oil = 10 : 90 (i.e. 100 μL DMSO → 900 μL Corn oil) Example: Take the Injection Formulation 3 (DMSO : Corn oil = 10 : 90) as an example, if 1 mL of 2.5 mg/mL working solution is to be prepared, you can take 100 μL 25 mg/mL DMSO stock solution and add to 900 μL corn oil, mix well to obtain a clear or suspension solution (2.5 mg/mL, ready for use in animals).

Injection Formulation 4: DMSO : 20% SBE-β-CD in saline = 10 : 90 [i.e. 100 μL DMSO → 900 μL (20% SBE-β-CD in saline)] Oral Formulations
Oral Formulation 1: Suspend in 0.5% CMC Na (carboxymethylcellulose sodium) Oral Formulation 2: Suspend in 0.5% Carboxymethyl cellulose Example: Take the Oral Formulation 1 (Suspend in 0.5% CMC Na) as an example, if 100 mL of 2.5 mg/mL working solution is to be prepared, you can first prepare 0.5% CMC Na solution by measuring 0.5 g CMC Na and dissolve it in 100 mL ddH2O to obtain a clear solution; then add 250 mg of the product to 100 mL 0.5% CMC Na solution, to make the suspension solution (2.5 mg/mL, ready for use in animals).

10 mM | 0.6752 mL | 3.3759 mL | 6.7517 mL |
*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
