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

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%

Thirty-one differently substituted pyrimidine bases were tested for their inhibitory effect on the glucuronidation of 4-nitrophenol and phenolphthalein by rat liver microsomes. 5-Nitrouracil (compound 1) and its isomer 4,6-dihydroxy-5-nitropyrimidine (compound 2) were the most potent and selective inhibitors of 4-nitrophenol

Several N-phenylhomophthalimide derivatives were prepared and their inhibitory activity on thymidine phosphorylase/ platelet-derived endothelial cell growth factor (TP/PD-ECGF) was assessed. Among them, 2-(2,6-diethylphenyl)-7-nitro-1,2,3,4-tetrahydroisoquinoline-1,3-dione (9) was found to be a more potent inhibitor than the classical inhibitor, 5-nitrouracil (1). Lineweaver-Burk plot
