Comparison of the antiviral effects of 5-methoxymethyl-deoxyuridine with 5-iododeoxyuridine, cytosine arabinoside, and adenine arabinoside.
The antiviral activity of 5-methoxymethyl-2'-deoxyuridine (MMUdR) was compared with that of 5-iodo-2'-deoxyuridine (IUdR), cytosine arabinoside (Ara-C), and adenine arabinoside (Ara-A). At concentrations of 2 to 4 mug/ml, MMUdR was inhibitory to herpes simplex virus type 1, but concentrations as high as 128 mug/ml were not inhibitory to three other herpesviruses tested (equine rhinopneumonitis ...

5-Ethynyl-2'-deoxyuridine (EdU) and 5-ethynyl-2'-deoxycytidine (EdC) are mainly used as markers of cellular replicational activity. Although EdU is employed as a replicational marker more frequently than EdC, its cytotoxicity is commonly much higher than the toxicity of EdC. To reveal the reason of the lower cytotoxicity of EdC, we performed a DNA analysis of five EdC-treated human cell lines. ...

متن کاملEvaluation of (5R,6R)-5-Bromo-6-Ethoxy-5-Ethyl-5,6-Dihydro-2\'- Deoxyuridine as a Brain-Targeted Prodrug of 5-Ethyl-2\'- Deoxyuridine
(+)-Trans-(5R,6R)-5-bromo-6-ethoxy-5-ethyl-5,6-dihydro-2'-deoxyuridine [(5R,6R)-BEEDU], a potential brain-targeted prodrug of 5-ethyl-2'-deoxyuridine (EDU), was synthesized by the regiospecific addition of BrOEt to the 5,6-olefinic bond of EDU. (5R,6R)-BEEDU is more lipophilic (log P = 0.04) than EDU (log P = -1.09). In vitro incubation of (5R,6R)-BEEDU with rat whole blood and brain homogena...
متن کاملBiological effects of 5-carboxy-2'-deoxyuridine: hydrolysis product of 5-trifluoromethyl-2'-deoxyuridine.
5-Carboxy-2'-deoxyuridine (5-COOH-2'-dUrd) is a product of the base-catalyzed hydrolysis of 5-trifluoromethyl-2'-deoxyuridine. Hydrolysis of 5-trifluoromethyl-2'-deoxyuridine to 5-COOH-2'-dUrd in phosphate-buffered saline was kinetically first order and was pH dependent. At 37 degrees C and pH 7.0, 7.5, and 8.0, hydrolysis occurred with rate constants of 4.19 x 10(-5), 9.30 x 10(-5), and 1.61 x...
