Transketolase-IN-3 (Cat No.: I042602) is a selective inhibitor of transketolase, a key enzyme in the non-oxidative branch of the pentose phosphate pathway (PPP). By targeting transketolase, this compound disrupts nucleotide biosynthesis and redox balance, making it a valuable tool for studying cancer metabolism and oxidative stress. Transketolase-IN-3 helps elucidate the role of PPP in tumor growth and metabolic reprogramming. It is particularly useful in exploring therapeutic strategies aimed at limiting cancer cell proliferation by impairing metabolic flexibility and antioxidant defense mechanisms.
