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
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
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. ^[6]

Working concentration: mg/ml;

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH₂O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
