idh1 mutants r132h

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.

AGI-5198 (IDH-C35) is a potent and selective inhibitor of IDH1 R132H and R132C mutants, with IC50 values of 0.07 μM and 0.16 μM, respectively.

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.

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].
