Biochem/physiol Actions

Tipiracil is an inhibitor of thymidine phosphorylase. Tipiracil is used in combination with trifluridine as TAS-102 for the treatment of refractory metastatic colorectal cancer. Tipiracil increases the bioavailability of trifluridine by blocking the enzyme that would otherwise protect the tumors by metabolizing trifluridine.
