TAS-102

半岛bd体育手机客户端 说明

一般描述

TAS-102 is a combination of two active ingredients: trifluridine (TFT), a nucleoside analog, and tipiracil (TPI), a thymidine phosphorylase inhibitor in a 1.0:0.5 molar ratio (TFT:TPI).¹TFT is the active antitumor component of TAS-102, its monophosphate form inhibits thymidylate synthase, an enzyme that plays a main role in DNA synthesis, and its triphosphate form is incorporated into DNA in tumor cells resulting in DNA dysfunction. TPI increases the bioavailability of TFT that is rapidly degraded to its inactive form by thymidine phosphorylase in the intestines and liver. The formulation presents a double targeted due to the cytotoxic effect of TFT, which is enhanced by TPI, while TPI also exerts antiangiogenic effects by inhibiting thymidine phosphorylase.²TAS 102 inhibits KM20C colon cancer xenograft growth by 70.5% when was orally administered twice daily at a dose of 150 mg/kg for 14 days.³TAS-102 has great potential to improve the treatment of malignancies when combined with other angiostatic or cytotoxic agents. A combination of TAS-102 and Avastin, an antineoplastic agent, was found to increase chemotherapeutic efficacy against colorectal cancer xenograft, compared with that for either drug alone.⁴
