Isocitrate dehydrogenases 1 and 2 (IDH1/2) are homodimeric enzymes. They catalyze the conversion of isocitrate to α-ketoglutarate (α-KG) in the tricarboxylic acid cycle. However, mutant IDH1/2 (mIDH1/2) reduces α-KG to the oncometabolite 2-hydroxyglutarate (2-HG). Inhibition of the mutant IDH (mIDH) protein represents a targeted approach to cancer treatment for...
