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.

Drug design and discovery, 12(1), 53-61 (1994-07-01)
The radiochemical syntheses of the [4-14C]-(-)-trans-(5S,6S)-5-bromo-5- ethyl-6-methoxy-5,6-dihydro-2'-deoxyuridine [2,(5S,6S)-BMEDU] and (+)-trans-(5R,6R)-5-bromo-5-ethyl-6- methoxy-5,6-dihydro-2'-deoxyuridine [3,(5R,6R)-BMEDU] are reported. These BMEDU diastereomers were synthesized in 21 and 25% radiochemical yield, respectively, by direct addition of methyl hypobromite to the 5,6-olefinic bond of [4-14C]-5-ethyl-2'-deoxyuridine (EDU).

The aim of this study was to explain why 5-ethyldeoxyuridine (EUdR) showed cytotoxic activity against Ehrlich ascites tumour (EAT) cells in vitro but not in vivo. In vitro studies showed that EUdR was phosphorylated to nucleotides which inhibit thymidylate synthetase

We investigated the toxicity of intravitreal zinc sulfate, zinc gluconate, and ethyldeoxyuridine (EDU) in albino rabbits. Various concentrations of EDU were added to the infusion solution during pars plana vitrectomy. Retinal changes were observed by light microscopy after intravitreal injections

The penetration of 5-ethyl-2'-deoxyuridine (edoxudine, Aedurid) from gel base with and without the addition of urea and other adjuvant has been studied in an in vitro model using guinea pig skin. The formulation of 3% edoxudine gel with 5% urea
