In eukaryotic cells, Isocitrate Dehydrogenase (IDH1, IDH2 and IDH3) is an enzyme that catalyzes the decarboxylation of Isocitrate producing α-Ketoglutarate and CO2. Mutations in both isoforms of IDH (IDH1 and IDH2) are commonly found in human cancers. The Mutant Isocitrate Dehydrogenase (Mutant IDH) causes a ``gain-of-function'', which reduces its affinity for isocitrate and favors the conversion of α-ketoglutarate to D-2-Hydroxyglutarate. D-2-Hydroxyglutarate (D2HG) is present at low level in normal cells and tissues, but is significantly elevated in metabolic diseases and various cancers. D2HG functions as an ``oncometabolite'' promoting cellular transformation. Recent studies show that increased Mutant IDH activity is associated
