Biological Activity

Description Trifluridine (NSC 529182, NSC 75520, Viroptic, Trifluorothymidine, TFT) is an anti-herpesvirus antiviral agent by interacting viral DNA replication, used primarily on the eye.
Targets
DNA synthesis [1]
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. [1] 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. [2] Trifluridine inhibits proliferations of mouse bone marrow cells and human colorectal carcinoma cells implanted to nude mice dose-dependently. [3]
In vivo Trifluridine has significantly fewer swabs positive for HSV-1 than the untreated eyes in the infected rabbits. [4] 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. [5] 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.
