4-hydroxy-2-pyridone derivatives 2 were prepared by reaction of 3-amino-3-dialkylaminopropenoates with bis(2,4, 6-trichlorophenyl)malonate. These compounds were further reacted with a set of aldehydes to give bis(pyridyl)methanes 3 and 4. The newly synthesized compounds 2, 3 and 4 were evaluated in vitro

The breakdown of 5-fluoro-2'-deoxyuridine (FdUrd) to 5-fluorouracil (FUra) is catalyzed by the pyrimidine nucleoside phosphorylases, uridine phosphorylase and thymidine phosphorylase. The effects of nucleoside phosphorylase inhibitors on FdUrd and FUra elimination by the isolated perfused rat liver were investigated. The

New method for a synthesis of diazaphenoxathiin skeleton from 3-deazauracil derivatives is reported. It became possible to convert 3-deazauridine to 3-deazacytidine via an excellent intermediate "diazaphenoxathiin sulfoxide derivative".

One hundred and five nucleobase analogues were screened as inhibitors of dihydrouracil dehydrogenase (DHUDase, EC 1.3.1.2) from mouse liver. 5-Benzyloxybenzyluracil, 1-deazauracil (2,6-pyridinediol), 3-deazauracil (2,4-pyridinediol), 5-benzyluracil, 5-nitrobarbituric acid and 5,6-dioxyuracil (alloxan) were identified as potent inhibitors of this activity, with apparent

A rapid and simple procedure for liquid chromatographic analysis of plasma 3-deazauridine (3-DU), an antineoplastic agent, was developed. The plasma was extracted with methanolic silver acetate to remove interfering ultraviolet-absorbing materials and the 3-DU partially purified on a small anion
