AGI-5198 (135526-35-0) is a potent (IC50 = 70 nM) inhibitor of mutant isocitrate dehydrogenase 1(IDH1).1 It is selective for the R132H-IDH1 mutant and does not affect wild type cells.2 This mutation results in loss-of-function for oxidative decarboxylation of isocitrate and gain-of-function for production of the oncometabolite R-2-hydroxyglutarate (R-2HG) from alpha-ketoglutarate (2-OG).
