mutant idh1-in-2

Mutant IDH1-IN-2 is an inhibitor of mutant Isocitrate dehydrogenase (IDH) proteins, with an IC50 of 16.6 nM in fluorescence biochemical assay and an IC50 of <22 nM in LS-MS biochemical assay.

Mutant IDH1-IN-3 (Compound 1) is a selective allosteric inhibitor targeting the mutant isocitrate dehydrogenase 1 (IDH1), with an IC50 of 13 nM for R132HIDH1. It effectively suppresses the production of D-2-hydroxyglutarate (2HG) in cells and is applicable for research in oncology.

ML-309 is an inhibitor of mutant isocitrate dehydrogenase 1 (IDH1). It reversibly and selective inhibits IDH1R132H over wild-type IDH1 (IC50s = 96 and 36,500 nM, respectively). ML-309 reduces 2-hydroxyglutarate production in U87 MG glioblastoma cells (EC50 = 55 nM).

mIDH1-IN-1 (compound 43) is a potent and selective inhibitor of mIDH1 (isocitrate dehydrogenase 1 mutant) with an IC50 of 961.5 nM, and it effectively inhibits the production of 2-HG (2-hydroxyglutarate) in HT1080 cells. It also exhibits significant anti-proliferative effects on IDH1 mutant U-87 cells (IC50: 41.8 nM). mIDH1-IN-1 is an anti-tumor agent used to study IDH1 mutant solid tumors.

(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.

ML309 is a potent inhibitor of R132H mutant IDH1 capable of reducing 2-hydroxyglutarate production in U87 MG glioblastoma cells. ML309 is capable of potent and selective inhibition of mutant IDH1 and effectively lowers cell-based production of 2-HG in a U87MG mutant glioblastoma cell line.

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].
