IDH1 Inhibitor 1 is an orally bioavailable, brain-penetrant, and selective mutant IDH1 inhibitor (IC50s: 0.021 μM, 0.045 μM, and 2.52 μM for IDH1R132H, IDH1R132C, and IDH1WT).
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).
