生物活性
Olutasidenib (FT-2102) is a highly potent and selective, orally active, brain penetrant mutant Isocitrate dehydrogenase 1 (IDH1) inhibitor, with IC50 values of 21.2 nM and 114 nM for IDH1- R132H and IDH1- R132C, respectively. Olutasidenib potently inhibits 2-HG production by multiple IDH1-R132 mutants (R132H, R132C, R132G, R132L), suggesting olutasidenib could be efficacious against most IDH1-R132 mutant-expressing tumors. Olutasidenib is highly selective for IDH1 isoforms, showing no appreciable inhibition against wild-type IDH1 and IDH2 mutants.
In vivo, Olutasidenib (12.5, 25, and 50 mg/kg; oral) in 12-hour intervals exhibits potent anti-tumor activity in HCT116-IDH1-R132H/+ xenograft bearing female BALB/c Nude mice. Olutasidenib has good cell permeability and low efflux ratio in the male CD-1 mouse, which indicate a low probability of p-glycoprotein driven efflux.
