Trifluridine/tipiracil hydrochloride mixture (TAS-102) is a potent and orally active nucleoside antitumor agent. The composition of Trifluridine/tipiracil hydrochloride mixture (TAS-102) is a 1:0.5 mixture (on a molar basis) of alpha,alpha,alpha-tri-fluorothymidine (FTD) and thymidine phosphorylase inhibitor (TPI). Trifluridine/tipiracil hydrochloride mixture (TAS-102) shows the antitumor activity mainly via the inhibition ofthymidylate synthase(TS) and incorporation into DNA^[1][2].

Trifluridine/tipiracil hydrochloride mixture (150 mg/kg/day; p.o.; twice a day for 14 days) prevents body weight loss and reduces the relative tumor volume in colorectal cancer and gastric cancer mice models^[2].
