Biological Activity

Description
The Trifluridine/tipiracil hydrochloride mixture (TAS-102) is an effective and orally active nucleoside antitumor agent. Comprised of a 1:0.5 molar ratio of alpha,alpha,alpha-tri-fluorothymidine (FTD) and thymidine phosphorylase inhibitor (TPI), TAS-102 exerts its antitumor effects predominantly through the inhibition of thymidylate synthase (TS) and by being incorporated into DNA[1].[2].
