Figure 1. Inhibition of 2-hydroxyglutarate production in heterozygotic IDH-1 cells.
Wild-type IDH-1 converts isocitrate to alpha-ketoglutarate. Heterozygotic IDH-1 (R132H) mutant protein can convert alpha-ketoglutarate to 2-hydroxyglutarate, an onco-metabolite. Selective therapeutics against IDH-1 (R132H) prevent 2-hydroxyglutarate production while leaving normal IDH-1 enzymatic function intact.
