Trifluridine 是一种抗疱疹病毒药,主要用于眼部。 三氟胸苷 (TFT) 是一种用于研究胸苷激酶特异性和动力学的底物。磷酸化后的 TFT 可掺入 DNA,诱导 DNA 损伤,因此 TFT 可用于研究 DNA 修复机制。TFT 也可用于研究胸苷酸合成酶抑制机制。
Information
Trifluridine (NSC 75520) Trifluridine (NSC 529182, NSC 75520, Viroptic, Trifluorothymidine, TFT) is an anti-herpesvirus antiviral agent by interacting viral DNA replication, used primarily on the eye.
In vitro
Trifluridine inhibits proliferations of mouse bone marrow cells and human colorectal carcinoma cells implanted to nude mice dose-dependently. Trifluridine inhibits colony formation of bone marrow cells in a concentration-dependent manner. Trifluridine (FTD) and 2\'-deoxy-5-fluorouridine (FdUrd) are incorporated into DNA with different efficiencies due to differences in the substrate specificities of TK1 and DUT, causing abundant FTD incorporation into DNA. FTD-treated cells shows differing nuclear morphologies compared to FdUrd-treated cells. Trifluridine inhibits proliferations of mouse bone marrow cells and human colorectal carcinoma cells implanted to nude mice dose-dependently.
In vivo
Trifluridine has significantly fewer swabs positive for HSV-1 than the untreated eyes in the infected rabbits. Trifluridine has increased antitumor activity and is incorporated into DNA more effectively than continuously infused Trifluridine in mice. Trifluridine gradually accumulates in tumor cell DNA, in a TPI-independent manner, and significantly delays tumor growth and prolonged survival in mice, compared to treatment with 5-FU derivatives. Trifluridine results in significantly lower viral titers, fewer HSV-1-positive eyes/total during the treatment period, lower keratitis scores, fewer eyes with keratitis/total, and a shorter time to resolution of keratitis in the New Zealand rabbit ocular model.
