چکیده

Phosphonoformate was found to be an inhibitor of the deoxyribonucleic acid polymerase induced by the herpesvirus of turkeys. The apparent inhibition constants were 1 to 3 muM. Phosphonoformate was also able to block the replication in cell culture of Marek's disease herpesvirus, the herpesvirus of turkeys, and herpes simplex virus. It was as effective as phosphonoacetate. Phosphonoformate was not an effective inhibitor of a phosphonoacetate-resistant mutant of the herpesvirus of turkeys nor of its induced deoxyribonucleic acid polymerase.

Phosphonoformate and Phosphonoacetate

Mutants of herpes simplex virus type 1, resistant to phosphonoformate (PFA) and phosphonoacetate (PAA), have been selected in cell culture. The PFAresistant mutant (HSV-PFAr) and the PAA-resistant mutant (HSV-PAAr) were also resistant to PAA and PFA, respectively. This cross-resistance indicates that PFA and PAA interact at the same site. The HSV-PFAr had a decreased susceptibility to vidarabin...

Mutually exclusive inhibition of herpesvirus DNA polymerase by aphidicolin, phosphonoformate, and acyclic nucleoside triphosphates.

Dual inhibitor studies were performed to examine the interaction of aphidicolin, phosphonoformate, 9-(2-hydroxyethoxymethyl)guanine triphosphate, and 9-(1,3-dihydroxy-2-propoxymethyl)guanine triphosphate with herpes simplex virus DNA polymerase. Kinetic data indicated that inhibition by one agent prevents simultaneous inhibition by a second agent, producing a mutually exclusive inhibition patte...

Sodium Valproate-Induced Potentiation of Antiherpetic Effect of Acyclovir

Background: Sodium valproate (VPA), an anticonvalsant drug, has been reported to stimulate viral replication.  A combination therapy with VPA and acyclovir (ACV) is used for the treatment of herpesvirus encephalitis, the commonest sporadic encephalitis of viral origin. Objective: To determine a possible interaction between VPA and ACV leading to a modification of antiviral activity of ACV. Meth...

Induction of deoxyribonucleic acid synthesis and the oncogenicity of Marek's disease virus.

Leukocytes recovered from birds inoculated with an oncogenic strain of Marek's disease virus synthesized deoxyribonucleic acid in vitro at a rate 7.9 times that of leukocytes from normal birds or birds inoculated with the nononcogenic herpesvirus of turkeys. A close relationship was observed between the level of in vitro deoxyribonucleic acid synthesis and in vivo tumor formation.

Hydroxyquinolines inhibit ribonucleic acid-dependent deoxyribonucleic acid polymerase and inactivate Rous sarcoma virus and herpes simplex virus.

8-Hydroxyquinoline and several of its derivatives inactivate the transforming ability of Rous sarcoma virus and inhibit its ribonucleic acid-dependent deoxyribonucleic acid polymerase activity. The copper complex of these metal-binding ligands is as active as the free ligand. The activity of the 8-hydroxyquinolines is approximately 50-fold more effective than another group of metal-binding comp...
