2-hydroxypentanedioic acid Chemical Properties,Usage,Production
Description
α-Hydroxyglutaric acid (2-HG) is an α-hydroxy acid. It is metabolized to 2-oxoglutarate by D- and L-2-hydroxyglutarate dehydrogenases, and mutations in these enzymes lead to 2-hydroxyglutaric aciduria, a neurometabolic disorder characterized by increased levels of L-2-hydroxyglutaric acid . 2-HG can also be metabolized from isocitrate by mutated forms of isocitrate dehydrogenase 1 (IDH1) and IDH2. 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.
Chemical Properties
White to Off-White Solid
Uses
2-Hydroxyglutaric acid is a potential inhibitor of glutamate carboxypeptidase.
Biochem/physiol Actions
D-(or R-) enantiomer of α-hydroxyglutaric acid is a cancer related biomarker of diagnostic value, whereas the L-(or S-) enantiomer of α-hydroxyglutaric acid is a biomarker for certain neurometabolic, inherited disorder diseases. It has no known physiological function in eukaryotes. It is toxic to the brain and increases the susceptibility to develop brain tumors.
in vitro
in humans the enzyme hydroxyacid-oxoacid transhydrogenase catalyzed the formation of d-α-hydroxyglutaric acid, while d-α-hydroxyglutaric acid is catalyzed by 2-hydroxyglutarate synthase in bacteria. recent study discovered heterozygous somatic mutations in the genes encoding isocitrate dehydrogenase-1 and -2 (idh1 and idh2) and these mutations could disable the enzymes' ability to convert 2-ketoglutarate to d-α-hydroxyglutarate. the authors also found heterozygous germline mutations in idh2 that alter enzyme residue in patients with d-2-hydroxyglutaric aciduria, a neurometabolic disorder characterized by supraphysiological levels of d-α-hydroxyglutaric acid [1].
in vivo
previous animal study demonstrated that the overexpression of the isocitrate dehydrogenase-1 (idh1) mutation resulted in detectable levels of d-α-hydroxyglutaric acid in a mouse glioma model that could be measured in vivo and noninvasively by mrs. results showed that this mouse model system was of potential application in establishing the relationships among d-α-hydroxyglutaric acid levels and treatment effect, outcomes, as well as other related and necessary variables to validate d-α-hydroxyglutaric acid as a clinically important biomarker for glioma [2].
