AGI-6780 is a selective inhibitor of IDH2/R140Q a tumor-associated mutant of isocitrate dehydrogenase IDH2.
AGI-6780 is a selective inhibitor of IDH2/R140Q a tumor-associated mutant of isocitrate dehydrogenase IDH2. Several human cancers have somatic point mutations in the genes encoding isocitrate dehydrogenases 1 and 2 (IDH1 and IDH2), confering a gain-of-function in cancer cells in which the mutant enzymes produce the oncometabolite (R)-2-hydroxyglutarate, [(R)-2HG]. (R)-2HG inhibits histone- and DNA-modifying enzymes, resulting in altered gene expression, histone and DNA hypermethylation, and inducing a block in cellular differentiation that promotes tumorigenesis. AGI-6780 reduced (R)-2HG levels in cell lines overexpressing IDH2/R140Q with an EC50 of 20 nM, and induced differentiation of TF-1 erythroleukemia and primary human acute myelogenous leukemia cells in vitro. AGI-6780 binds allosterically at the dimer interface of IDH2. AGI-6780 shows good selectivity against other dehydrogenases, including the closely related IDH1-WT or R132H mutant enzymes.
