Abstract

A fresh look at glutamine targeting Glutamine is essential for tumor growth and has long been an attractive therapeutic target for cancer researchers. Some attempts at blocking glutamine metabolism in cancer patients resulted in toxicity, prompting Leone et al. to develop an innovative approach to reduce general side effects. They designed a prodrug form (JHU083) of the glutamine antagonist 6-diazo-5-oxo- l -norleucine (DON), which is administered in an inert state but then preferentially activated by enzymes enriched in the tumor microenvironment. JHU083 simultaneously shut down glycolysis and oxidative phosphorylation in mouse cancer cells while enhancing T cell oxidative phosphorylation and anticancer immune responses.
