title: Synthesis of 1-beta-D-ribofuranosyl-1,2-dihydropyrimidin-2-one derivatives and their biological activities.
abstract: Several alkyl substituted 1-beta-D-ribofuranosyl-1,2-dihydropyrimidin-2-one derivatives were synthesized by the method of stannic chloride-catalyzed glycosidation method to elucidate their inhibitory activity of cytidine deaminase and also their antitumor activities in vitro and in vivo. Alkyl substitution at position 4 or 6 of the derivatives decreased their inhibitory activity for cytidine deaminase and also decreased antitumor activity against L1210 cells in vitro.
