Olutasidenib

Olutasidenib (FT-2102) is a highly potent, orally active, brain penetrant and selective inhibitor of mutant Isocitrate dehydrogenase 1 (IDH1), with IC₅₀ values of 21.2 nM and 114 nM for IDH1- R132H and IDH1- R132C, respectively . Olutasidenib (FT-2102) is under the study in the treatment of acute myeloid leukemia (AML) or myelodysplastic syndrome (MDS) ^[1][2]. IC50 & Target:IC50: 21.2 nM (IDH1- R132H), 114 nM (IDH1- R132C)^[2]. In Vitro:Olutasidenib (FT-2102) potently inhibits 2-HG production by multiple IDH1-R132 mutants (R132H, R132C, R132G, R132L), suggesting Olutasidenib (FT-2102) could be efficacious against most IDH1-R132 mutant-expressing tumors. Olutasidenib (FT-2102) is highly selective for IDH1 isoforms, showing no appreciable inhibition against wild-type IDH1 (> 20 µM) and IDH2 mutants (R172K and R140Q: both > 20 µM)^[2]. In Vivo:Olutasidenib (FT-2102, three oral doses (12.5, 25, and 50 mg/kg) in 12-hour intervals) exhibits potent anti-tumor activity in HCT116-IDH1-R132H/+ xenograft bearing female BALB/c Nude mice^[2].
