Mutant isocitrate dehydrogenase in cancer: Structural biology, small-molecule inhibitors, and future drug discovery strategies.
Isocitrate dehydrogenase (IDH) enzymes convert isocitrate to α-ketoglutarate. When IDH1 or IDH2 is mutated, the enzyme gains a new function, and the oncometabolite D-2-hydroxyglutarate (D-2-HG) accumulates. Its epigenetic and metabolic effects depend on the tumor context. This review classifies mutant IDH inhibitors by...
