Cat.No. 2755 - DCA | C2HCl2NaO2 | CAS No. 2156-56-1
Description: Mitochondrial pyruvate dehydrogenase kinase (PDK) inhibitor
Chemical Name: Sodium dichloroacetate

Biological Activity

Inhibitor of mitochondrial pyruvate dehydrogenase kinase (PDK). Shifts pyruvate metabolism from glycolysis and lactate production to glucose oxidation in the mitochondria. Induces mitochondrial-dependent apoptosis and reverses the inhibition/downregulation of KV1.5 channels in cancer but not normal cells. Decreases tumor growth in vitro and in vivo.

Preparing Stock Solutions

The following data is based on the product molecular weight 150.92. Batch specific molecular weights may vary from batch to batch due to solvent of hydration, which will affect the solvent volumes required to prepare stock solutions.

Concentration / Solvent Volume / Mass 1 mg 5 mg 10 mg
1 mM 6.63 mL 33.13 mL 66.26 mL
5 mM 1.33 mL 6.63 mL 13.25 mL
10 mM 0.66 mL 3.31 mL 6.63 mL
50 mM 0.13 mL 0.66 mL 1.33 mL
