Description: Lactate dehydrogenase inhibitor; impairs aerobic glycolysis
Chemical Name: 3,8,9,10-Tetrahydroxypyrano[3,2-c][2]benzopyran-2,6-dione potassium salt
Purity: ≥95% (HPLC)
Biological Activity
Inhibitor of human lactate dehydrogenase (LDH) (Ki values are 5.46 and 15.1 μM for LDH-A and LDH-B, respectively, in competition with pyruvate). Inhibits lactate production and decreases ATP synthesis in PLD/PRF/5 cells; thought to decrease cell viability via impairment of aerobic glycolysis.
