[https://www.uniprot.org/uniprot/IDHP_HUMAN IDHP_HUMAN] D-2-hydroxyglutaric aciduria. Defects in IDH2 are the cause of D-2-hydroxyglutaric aciduria type 2 (D2HGA2) [MIM:[https://omim.org/entry/613657 613657]. D2HGA2 is a neurometabolic disorder causing developmental delay, epilepsy, hypotonia, and dysmorphic features. Both a mild and a severe phenotype exist. The severe phenotype is homogeneous and is characterized by early infantile-onset epileptic encephalopathy and cardiomyopathy. The mild phenotype has a more variable clinical presentation. Diagnosis is based on the presence of an excess of D-2-hydroxyglutaric acid in the urine.<ref>PMID:20847235</ref>

A number of human cancers harbor somatic point mutations in the genes encoding isocitrate dehydrogenases- 1 and -2 (IDH1, IDH2). These mutations alter residues in the enzyme active sites and confer a gain-of-function in cancer cells, resulting in the accumulation and secretion of the oncometabolite R (-)-2-hydroxyglutarate (2HG). We developed a small molecule, AGI-6780, that potently and selectively inhibits the tumor-associated mutant IDH2/R140Q. A crystal structure of AGI-6780 complexed with IDH2/R140Q revealed that the inhibitor binds in an allosteric manner at the dimer interface. The results of steady-state enzymology analysis were consistent with allostery and slow-tight binding by AGI-6780. Treatment with AGI-6780 induced differentiation of TF-1 erythroleukemia and primary human acute myelogenous leukemia (AML) cells in vitro. These data provide proof-of-concept that inhibitors targeting mutant IDH2/R140Q could have potential applications as a differentiation therapy for cancer.
