The kinetics of conversion of 5-fluoro-2'-deoxyuridine (FdUrd) to 5-fluorouracil (FUra) by isolated rat intestinal epithelial cells was investigated. Also, the effects of potential inhibitors of this reaction, which is catalyzed by uridine phosphorylase and thymidine phosphorylase, were determined. A 2.5%

The high-resolution IR-spectra of 5-nitrouracil and 5-bromouracil isolated in Ar matrices at 11 K were obtained for the first time. The conformational structure of uracil 5-substituents--thymine, 5-bromouracil, 5-nitrouracil--is calculated by the molecular mechanics and quantum--chemical MINDO/3 methods. The possibility of

tRNA in which uracil is completely replaced by 5-nitro-uracil was prepared by substituting 5-nitro-UTP for UTP in an in vitro transcription reaction. The rationale was that the 5-nitro substituent activates the 6-carbon of the Ura heterocycle towards nucleophiles, and hence

The degradation of 3H-thymidine under various cell culture conditions was analysed. It was found that a half of 3H-thymidine was degraded to 3H-thymine during 24 hours in PHA stimulation of blood lymphocytes. A control culture in which PHA was not

A few organisms, notably some fungi, have the ability to metabolize thymidine to uracil, thus conserving the pyrimidine ring for subsequent metabolic use. Neurospora crassa possesses this pathway, termed the thymidine salvage pathway, and can utilize thymidine as a total
