5-Fluoro-2′-deoxyuridine is an experimental anticancer agent shown to have activity against a variety of malignant neoplasms, including mouse mammary tumors and colorectal carcinomas. 5-Fluoro-2#39-deoxyuridine is an inhibitor of TS. 5-Fluoro-2′-deoxyuridine, a fluorinated pyrimidine nucleoside analog, serves as a prodrug that undergoes activation through liver catalysis. In vitro studies primarily involve cell cultures, utilizing 5-Fluoro-2′-deoxyuridine to investigate its impact on cellular processes such as growth, differentiation, and gene expression. Notably, it has been employed to examine the effects of this drug on DNA synthesis, cell cycle progression, and apoptosis in cell cultures, shedding light on its mechanisms of action and potential therapeutic benefits.
