Application
三氟胸苷已用作选择性培养基组分，用于筛选淋巴瘤细胞、人淋巴母细胞样细胞TK6和小鼠淋巴瘤细胞L5178Y中的胸苷激酶(TK)突变体。
Biochem/physiol Actions
三氟胸苷(TFT)是一种胸苷类似物，对光敏感。TFT可作为胸苷激酶底物，用于研究该酶的特异性和动力学。磷酸化TFT可掺入DNA，诱导DNA损伤，因而TFT适合用于研究DNA修复机制。TFT也可用于研究胸苷酸合成酶抑制机制和筛选胸苷激酶突变基因。它对胃肠道癌具有抗肿瘤活性，也可用于治疗疱疹病毒性角膜炎。

A physiological decrease in extracellular pH (pHe) alters the efficiency of DNA repair and increases formation of DNA double-strand breaks (DSBs). Whether this could translate into genetic instability and variations, was investigated using the TK6 cell model, in which positive

Trifluorothymidine (TFT) is well known to be converted to TFT-monophosphate by thymidine kinase and to inhibit thymidylate synthase. In addition, TFT-triphosphate (TFT-TP) is also incorporated into DNA, resulting in cytocidal effects. However, the precise mechanism of TFT-induced DNA damage is
