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].

Isocitrate dehydrogenase (ICDH), a critical enzyme in the citric acid or tricarboxylic acid cycle, facilitates the oxidative decarboxylation of isocitrate to α-ketoglutarate while reducing NAD(P)+ to NAD(P)H, thus playing pivotal roles in cellular metabolism [1].

GSK864 is an IDH1 mutant inhibitor that inhibits IDH1 mutants R132C, R132H, and R132G, and is used in the study of cardiovascular and oncology diseases.

IDH2R140Q-IN-2 is an orally active and potent IDH2R140Q inhibitor with an IC50 of 29 nM.IDH2R140Q-IN-2 possesses potential antitumour activity, reducing D2HG production in TF-1 cell lines carrying the IDH2R140Q mutation (IC50 of 10 nM) and inhibiting tumour tissue D2HG levels.IDH2R140Q-IN-2 is suitable for the study of acute myeloid leukaemia (AML).
