Description: Dipotassium (R)-2-Hydroxyglutarate is a potent and competitive inhibitor of α-ketoglutarate (α-KG)-dependent dioxygenases with Ki value of 0.628 mM. In U-87MG cells, (R)-2-Hydroxyglutarate acts as weak antagonists of α-KG to inhibit α-KG-dependent histone demethylases and increases dimethylation on both H3K9 and H3K79. Besides, (R)-2-Hydroxyglutarate also inhibits ATP synthase and mTOR signaling, and therefore causes growth arrest and tumor cell killing. Inhibition of ATP synthase by 2-HG or α-KG in glioblastoma cells is sufficient for growth arrest and tumor cell killing under conditions of glucose limitation, e.g., when ketone bodies (instead of glucose) are supplied for energy. These findings inform therapeutic strategies and open avenues for investigating the roles of 2-HG and metabolites in biology and disease.
