title: Inhibitory potency of 5-benzyluracil, 5-phenylcytosine and 5-phenylpyrimidin-2-one nucleosides against uridine phosphorylase from mouse leukemic L1210 cells.
abstract: The inhibitory activity of a series of novel sugar-modified nucleosides derived from 5-benzyluracil, 5-phenylcytosine and 5-phenylpyrimidin-2-one against uridine phosphorylase purified from mouse leukemic L-1210 cells was investigated. Significant activity was encountered with O2,2'-anhydro-5-benzylcytidine hydrochloride, 2',3'-dideoxy-5-benzyluridine, 2',3'-dideoxy-4-thiouridine and alpha- and beta-anomers of 5-benzyl-1-(2-deoxy-D-arabino-hexopyranosyl)uracil.
