Handling Instructions Technical Support

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 of thymidylate synthase (TS) and incorporation into DNA.

    Description

    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 of thymidylate synthase (TS) and incorporation into DNA[1][2].

    Help & FAQs
    • Do most proteins show cross-species activity?

      Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
