title: Differential effect of nucleoside analog triphosphates on ribonucleotide reductases from uninfected and herpes simplex virus-infected HeLa cells.
abstract: Effects of the triphosphates of eight pyrimidine nucleoside analogs (5-substituted, 2'-fluoroara-, and acyclonucleosides) and acycloguanosine were examined on the ribonucleotide reductases prepared from uninfected and herpes simplex virus (types 1 and 2)-infected HeLa cells. Of the analogs tested, E-5-propenyl- and E-5-(2-bromovinyl)-dUTP were more potent inhibitors than dTTP of the enzymes from virus-infected cells, whereas only the former compound showed this effect on the uninfected HeLa enzyme.
