Mechanism of action

Trifluridine is a nucleoside analog that inhibits thymidylate synthase, an enzyme involved in DNA synthesis. Tipracil is a prodrug that is converted to 5-fluorouracil, which inhibits dihydrofolate reductase, another enzyme involved in DNA synthesis. This dual inhibition leads to the inhibition of DNA synthesis and cell death in rapidly dividing cells, such as cancer cells.
