Selective activation of a prodrug by thioredoxin reductase providing a novel strategy to target cancer cells. Li, X., Hou, Y., Meng, X., Ge, C., Ma, H., Li, J., & Fang, J. Angewandte Chemie (International Ed. in English), March, 2018. doi abstract bibtex Elevated reactive oxygen species and antioxidant defense systems have been recognized as one of the hallmarks of cancer cells. As a major regulator of the cellular redox homeostasis, the selenoprotein thioredoxin reductase (TrxR) is increasingly considered as a promising target for anticancer drug development. The current approach to inhibit TrxR predominantly relies on the modification of the selenocysteine residue in the C-terminal active site of the enzyme, which is hard to avoid the off-target effects. By conjugating the anticancer drug gemcitabine with a 1, 2-dithiolane scaffold, we disclosed here an unprecedented prodrug strategy that achieves a specific release of gemcitabine by TrxR in cells. As overexpression of TrxR is frequently found in different types of tumors, the TrxR-dependent prodrugs are promising for further development as cancer chemotherapeutic agents.
