DS-1001b (Safusidenib t-Butylamine) is a potent, orally bioavailable, selective mutant IDH-1 (Isocitrate Dehydrogenase-1) inhibitor with antitumor activity. DS-1001b (Safusidenib t-Butylamine) impairs the proliferation of IDH1 mutant chondrosarcoma cell lines and decreases 2-HG levels. DS-1001b exhibits activity against IDH1R132H, and IDH1R132C with IC50s of 15, and 130 nM in assays without any preincubation, respectively.
In vivo, Safusidenib (DS-1001b) has antineoplastic activity in JJ012 xenografts. Continuous administration of Safusidenib (mixed with sterilized pellet food and fed continuously for 6 weeks) impairs tumor growth in xenograft mice.
