IDH305

IDH305 is a potent and selective inhibitor of mutant isocitrate dehydrogenase 1 (IDH1, IC50s = 27, 28, and 6,140 nM for recombinant IDH1R132H, IDH1R132C, and wild-type IDH1, respectively). It reduces R-2-hydroxyglutarate (2-HG) production, a marker of mutant IDH1 activity, and inhibits growth of MCF-10A-IDH1R132H/+ cells in a concentration-dependent manner but has no effect on HCT116 cells expressing mutant IDH2. IDH305 (200 mg/kg) reduces the concentration of tumor 2-HG in an HCT116-IDH1R132H/+ mouse xenograft model. It also suppresses 2-HG production and reduces tumor progression in an HMEX2838-IDH1R132C patient-derived melanoma mouse xenograft model when administered at a dose of 300 mg/kg.Formal Name: (4R)-4-[(1S)-1-fluoroethyl]-3-[2-[[(1S)-1-[4-methyl-2'-(trifluoromethyl)[3,4'-bipyridin]-6-yl]ethyl]amino]-4-pyrimidinyl]-2-oxazolidinone.
