ML309 is a potent and selective inhibitor of the R132H mutant isocitrate dehydrogenase 1 (IDH1 R132H) with an IC50 of 96 nM. It acts as a competitive inhibitor of α-ketoglutarate (α-KG), exhibiting a Ki value of 156 nM while demonstrating minimal inhibition of wild-type IDH1. In in vitro studies, ML309 effectively decreases the production of the oncometabolite 2-hydroxyglutarate (2-HG) in U87MG cells. This compound serves as a valuable chemical probe for investigating the role of mutant IDH1 in cancer progression and therapeutic response.
