An inhibitor of mutant IDH1 and IDH2
Vorasidenib (AG-881) is an orally available, brain penetrant second-generation dual mutant isocitrate dehydrogenases 1 and 2 (mIDH1/2) inhibitor. Vorasidenib (AG-881) exhibits nanomolar inhibition of (D)-2-hydroxyglutarate (D-2-HG), and the IC50 ranges of 0.04~22 nM against IDH1 R132C, IDH1 R132G, IDH1 R132H and IDH1 R132S and 7~14 nM against IDH2 R140Q and 130 nM against IDH2 R172K[1][2].
Vorasidenib has strong antiproliferative activity against human glioblastoma U-87 MG pLVX-IDH2 R140Q-neo, fibrosarcoma HT-1080 and neurosphere TS603 cells, all with IC50s of less than 50 nM[2].
