Biochem/physiol Actions

5-Ethyl-2′-deoxyuridine (EUdR) is used as a 5-fluorouracil (FU) modulator. EtdUrd may be used to enhance the therapeutic index of 5-FU by reducing the catabolism, prolonging the plasma and intratumoral concentrations of 5-FU, and offering protection to normal organs by increasing the endogenous uridine levels.
5-Ethyl-2′-deoxyuridine is an analog of pyrimidine, uridine. It is an effective antiviral agent and inhibits cell division in leukemic tumor cells. 5-Ethyl-2′-deoxyuridine interacts with 2′-deoxycytidine phosphate (dCTP) biosynthesis pathway to elicit antiproliferative effects.

Using an in vitro system we measured the corneal epithelial cytotoxicity and the antiviral activity of the antiviral agents idoxuridine (IDU), trifluridine (TFT), ethyldeoxyuridine (EDU), and (E)-5-(2-Bromovinyl)-2'-deoxyuridine (BVDU). Confluent rabbit corneal epithelial cell cultures were established, and the antiviral agents
