ONC213 is an orally active αKGDH inhibitor. ONC213 can suppress mitochondrial respiration and elevate α-ketoglutarate levels by inhibiting αKGDH activity. ONC213 can induce cells apoptosis by inducing mitochondrial stress response and inhibiting translation of MCL-1. ONC213 can be used for the research of cancer, such as acute myeloid leukemia research (AML) [1].
