Additional Information

ML309 represents an important compound to study the role of mutant (R132H) IDH1 in cancer cells as well as the metabolic consequences of its expression. As a potent and selective inhibitor of the R132H mutant IDH1 with good cell-based activity, this compound is poised for use in various cellular contexts as well as for potential use in in vivo proof of concept models. The compound has IC50s of 96 nM and >35μM against mutant and wild-type IDH1 respectively, and a 500 nM EC50 in the cell-based 2-hydroxyglutarate production assay. Additionally, ML309 has good in vitro ADME and in vivo PK profile. Though it does not possess significant blood brain barrier (BBB) penetration in healthy mice, use in mice with compromised BBB (as is typically seen in glioblastoma) or the use in AML models is certainly warranted. As a first-in-class molecule with the aforementioned profile, we believe this compound will be quite useful to the scientific community.  (
