In contrast, reversible inhibitors bind non- covalently and different types of inhibition are produced depending on whether these inhibitors bind to the enzyme, the enzyme- substrate complex, or both. Inhibition of glycolysis using 2-deoxy-d-glucose (2DG, 20 mM, 24–48 h) combined with inhibition of the pentose cycle using dehydroepiandrosterone (DHEA, 300 µM, 24–48 h) increased clonogenic cell killing in both human prostate (PC-3 and DU145) and human breast (MDA-MB231) cancer cells via a mechanism involving thiol-mediated oxidative stress. 3.
