AS Triazine Acyclonucleosides: Potential Inhibitors of Pyrimidine Enzymes1

Abstract Seven as-triazine-3,5-dione acyclonucleosides were synthesized and evaluated as inhibitors of orotate phosphoribosyltransferase (OPRTase, EC 2.4.2.10), orotidine 5′-monophosphate decarboxylase (ODCase, EC 4.1.2.23), uridine phosphorylase (UrdPase, EC 2.4.2.3), and thymidine phosphorylase (dThdPase, EC 2.4.2.4).
