IDH2R140Q-IN-1 is a potent inhibitor of IDH2R140Q (IC50: 6.1 nM) and can be used in studies of acute myeloid leukemia.

AGI-6780 is a potent and selective inhibitor of IDH2 R140Q mutant.

D-α-Hydroxyglutaric acid disodium [Disodium (R)-2-Hydroxyglutarate] is a competitive inhibitor of α-ketoglutarate-dependent dioxygenases with a Ki of 0.628 mM.

Enasidenib mesylate (AG-221 mesylate) is a potent and selective IDH2 mutase inhibitor that promotes differentiation of leukemia myeloid cells for the treatment of acute myeloid leukemia.

BRD2879 is a potent and cell-active inhibitor of IDH1-R132H (IC50 = 50 nM).

Crelosidenib is a potent and selective mutant IDH inhibitor with IC50s of 6.27 nM, 3.71 nM, 36.9 nM, and 11.5 nM for IDH1 R132H, IDH1 R132C, IDH2 R140Q, and IDH2 R172K mutases, respectively, and low inhibitory activity against the wild-type IDH enzyme.

(S,R)-WT IDH1 Inhibitor 2 is a selective and potent mutant IDH1 inhibitor that inhibits R132G (IC50: 2.9 nM), R132C (IC50: 3.8 nM), R132H (IC50: 4.6 nM) and WT IDH1 (IC50: 46 nM) with 100-fold higher selectivity than IDH2. 100-fold higher selectivity than IDH2. (S,R)-WT IDH1 Inhibitor 2 is investigated in acute myeloid leukemia (AML) and other cancers for its ability to induce intracellular 2-HG reduction, failure of myeloid differentiation block, and induction of granulocyte differentiation at the level of leukemia mother cells and more immature stem cells.

Vorasidenib (PVM MA) is an inhibitor of mutant isocitrate dehydrogenase (IDH; IC50s = 31.9 and 31.7 nM for IDH1R132H and IDH2R140Q, respectively)

IHMT-IDH1-053 (compound 16) is an irreversible inhibitor highly selective for the IDH1 R132H mutant, with an IC50 of 4.7 nM. It preferentially targets IDH1 mutants over wild-type IDH1 and IDH2, in both their wild-type and mutant forms. In 293T cells transfected with the IDH1 R132H mutant, IHMT-IDH1-053 reduces 2-hydroxyglutarate (2-HG) production with an IC50 of 28 nM. The compound binds to the R132H protein at an allosteric site near the NADPH binding region, forming a covalent linkage with Cys269. Additionally, IHMT-IDH1-053 inhibits the growth of both the HT1080 cell line and primary acute myeloid leukemia (AML) cells harboring IDH1 R132 mutations [1].

IDH1 2-IN-1 (Compound 6b) is a dual inhibitor of IDH1(R132H) IDH2(R140Q) with IC50 values of 0.22 μM and 1.6 μM, respectively. This compound effectively inhibits tumor growth by suppressing tumor cell proliferation and activating antioxidative enzymes to enhance host defense. Additionally, IDH1 2-IN-1 reduces inflammation and promotes apoptosis, demonstrating significant anti-tumor activity. It is also utilized in leukemia research.

TQ05310 is an orally active inhibitor of mutant IDH2, targeting both IDH2-R140Q (IC50=136.9 nM) and IDH2-R172K (IC50=37.9 nM) mutations. This compound suppresses the production of 2-hydroxyglutarate (2-HG) by inhibiting the enzymatic activity of mutant IDH2, and induces differentiation in cells expressing IDH2-R140Q and IDH2-R172K. TQ05310 is utilized in research on acute myeloid leukemia.
