Pharmacology
IDH2 inhibitor; enasidenib is a small molecule that selectively targets mutant IDH2 variants (R140Q, R172S, R172K), decreasing 2-hydroxyglutarate (2-HG) levels and inducing myeloid differentiation in IDH2-mutated AML.
Olutasidenib is a small-molecule inhibitor of mutated isocitrate dehydrogenase-1 (IDH1); it inhibits mutant IDH1 proteins (R132H, R132C, and others), reducing 2-hydroxyglutarate (2-HG) levels in leukemia cells and promoting differentiation.
