Trifluridine , 三氟胸苷

Trifluorothymidine is a derivative of thymidine that exhibits antiviral and anticancer activity by inhibiting thymidylate synthase, thereby blocking nucleic acid synthesis, and by incorporating into DNA, which leads to DNA damage and apoptosis.

Trifluorothymidine is an inhibitor of TS (thymidylate synthase). It is also a substrate used to study the specificity and kinetics of thymidine kinases. Acts as an anti-herpesvirus drug by blocking viral DNA replication. Decreases CRISPR-mediated HDR (homology-directed repair) efficiency.

Trifluridine is a fluorinated thymidine analog with potential antineoplastic activity. Trifluridine is incorporated into DNA and inhibits thymidylate synthase, resulting in inhibition of DNA synthesis, inhibition of protein synthesis, and apoptosis. This agent also exhibits antiviral activity. (NCI04)

Trifluridine/tipiracil is the combination of an antineoplastic pyrimidine analogue (trifluridine) with an inhibitor of its metabolism (tipiracil) that is used in the therapy of refractory, metastatic colorectal cancer. Trifluridine/tipiracil is associated with a low rate of transient serum enzyme elevations during therapy, but has not been implicated in cases of clinically apparent acute liver injury with jaundice.

Trifluridine is a pyrimidine 2'-deoxyribonucleoside compound having 5-trifluoromethyluracil as the nucleobase. An antiviral drug used mainly in the treatment of primary keratoconjunctivitis and recurrent epithelial keratitis. It has a role as an antiviral drug, an antimetabolite, an EC 2.1.1.45 (thymidylate synthase) inhibitor and an antineoplastic agent. It is a nucleoside analogue, an organofluorine compound and a pyrimidine 2'-deoxyribonucleoside.
