Mecanismo de acción (Mechanism of Action)

Targets/IC₅₀/Ki	DNA synthesis
In vitro	Trifluridine (NSC 75520) inhibits proliferations of mouse bone marrow cells and human colorectal carcinoma cells implanted to nude mice dose-dependently. It also inhibits colony formation of bone marrow cells in a concentration-dependent manner. This compound 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. It further inhibits proliferations of mouse bone marrow cells and human colorectal carcinoma cells implanted to nude mice dose-dependently.
In vivo	Trifluridine (NSC 75520) has significantly fewer swabs positive for HSV-1 than the untreated eyes in the infected rabbits. This compound has increased antitumor activity and is incorporated into DNA more effectively than continuously infused Trifluridine in mice. It 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. Furthermore, it 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.
