AG-881 Chemical Structure
AG-881 is a potent and selective orally available inhibitor of mutated forms of both isocitrate dehydrogenase type 1 (IDH1, IDH1 [NADP+] soluble) in the cytoplasm and type 2 (IDH2, isocitrate dehydrogenase [NADP+], mitochondrial) in the mitochondria, with potential antineoplastic activity. AG-881 specifically inhibits mutant forms of IDH1 and IDH2, thereby inhibiting the formation of the oncometabolite 2-hydroxyglutarate (2HG) from alpha-ketoglutarate (a-KG). This prevents 2HG-mediated signaling and leads to both an induction of cellular differentiation and an inhibition of cellular proliferation in tumor cells expressing IDH mutations
