1. Regeneration of the antiviral drug (E)-5-(2-bromovinyl)-2'-deoxyuridine in vivo.

The highly potent and selective antiherpes drug BVdUrd [(E)-5-(2-bromovinyl)-2'-deoxyuridine] is cleared within 2-3 hours from the bloodstream upon intraperitoneal administration to rats. It is degraded to BVUra [(E)-5-(2-bromovinyl)uracil] and this inactive metabolite is cleared very slowly from the bloodstream so that 24 hours after the administration of B

2. Inhibition of glycosylation of bovine herpesvirus 1 glycoproteins by the thymidine analog (E)-5-(2 Bromovinyl)-2'-deoxyuridine.

(E)-5-(2-Bromovinyl)-2'-deoxyuridine (BVdU) was phosphorylated by the bovine herpesvirus 1 (BHV-1)-induced thymidine kinase and subsequently incorporated into viral DNA, resulting in DNA that was more dense than DNA from untreated cells. Incorporation of the drug did not result in the termination of replicating BHV-1 DNA molecules since radioactively labeled

3. Antigenic variations in bovine viral diarrhea viruses detected by monoclonal antibodies.

Five murine monoclonal antibodies (MAbs) against the NADL strain of bovine viral diarrhea (BVD) virus were developed, identified, and characterized. Four of the MAbs were directed against a 53-kilodalton (kDa) viral protein, and one was specific to a 47-kDa polypeptide. Competitive radioimmunoassay showed that two MAbs were specific to related epitopes of th

4. On the mechanism of selective inhibition of herpesvirus replication by (E)-5-(2-bromovinyl)-2'-deoxyuridine.

Bromovinyldeoxyuridine (BVdUrd) is a potent antiherpesvirus compound with low cytotoxicity. To gain an insight into its selectivity and mechanism of inhibition, we chemically synthesized the 5'-triphosphate of BVdUrd, BVdUTP, and tested its effect on the activities of DNA polymerases [DNA nucleotidyltransferase (DNA directed), EC 2.7.7.7] of two herpesviruse

5. Problems associated with the use of (E)-5-(2-bromovinyl)-2'-deoxyuridine for typing herpes simplex virus.

When 0.5 microgram of (E)-5-(2-bromovinyl)-2'-deoxyuridine (BVdU) per ml was incorporated directly into cell culture medium inoculated with eight known positive specimens, one herpes simplex virus type 1 (HSV-1) isolate grew in the presence of BVdU and was misidentified. By plaque assay, the titers of 15 HSV-1 strains were reduced by more than 3 log10 by BVd

6. Ocorrência de anticorpos contra os vírus da leucose enzoótica bovina, rinotraqueíte infecciosa bovina e diarreia viral bovina em bubalinos (Bubalus bubalis) no Estado do Pará

A leucose bovina, a diarréia viral bovina e a rinotraqueite infecciosa bovina estão entre as principais viroses que levam a perdas na produtividade e no desempenho reprodutivo de ruminantes. Embora bovinos e bubalinos sejam frequentemente criados em conjunto e apesar da comprovada ocorrência dessas enfermidades em bubalinos, trabalhos sobre ocorrência na

7. Inhibitory effect of E-5-(2-bromovinyl)-1-beta-D-arabinofuranosyluracil on herpes simplex virus replication and DNA synthesis.

The effect of E-5-(2-bromovinyl)-1-beta-D-arabinofuranosyluracil (BVaraU) on herpes simplex virus (HSV) replication was examined and compared with that of E-5-(2-bromovinyl)-2'-deoxyuridine (BVdUrd). The 50% inhibitory dose against HSV type 1 (HSV-1) was 0.1 microgram/ml compared with 0.008 microgram/ml for BVdUrd; the antimetabolic 50% inhibitory dose of BV

8. Comparative efficacy and selectivity of some nucleoside analogs against Epstein-Barr virus.

The effects of (2-deoxy-2-fluoro-beta-D-arabinofuranosyl)-5-iodocytosine (FIAC), 1-(2-deoxy-2-fluoro-beta-D-arabinofuranosyl)-5-methyluridine (FMAU), 1-(2-deoxy-2-fluoro-beta-D-arabinofuranosyl)-5-iodouridine (FIAU), (E)-5-(2-bromovinyl)-2'-deoxyuridine (BVdU), and 9-(1,3-dihydroxy-2-propoxymethyl)guanine (DHPG or BW B759U) on the replication of Epstein-Barr

9. Comparison of two bromovinyl nucleoside analogs, 1-beta-D-arabinofuranosyl-E-5-(2-bromovinyl)uracil and E-5-(2-bromovinyl)-2'-deoxyuridine, with acyclovir in inhibition of Epstein-Barr virus replication.

The effect of 1-beta-D-arabinofuranosyl-E-5-(2-bromovinyl)uracil (BV-araU), a new antiviral drug, on Epstein-Barr virus (EBV) was studied and compared with those of E-5-(2-bromovinyl)-2'-deoxyuridine (BVdU) and acyclovir (ACV). BV-araU effectively inhibited EBV replication both in superinfected Raji cells and in virus producer P3HR-1(LS) cells, as determined

11. InteraÃÃo das vias da ciclo-oxigenase-2 e da hemeoxigenase-1 / biliverdina / monÃxido de carbono no controle da nocicepÃÃo e da inflamaÃÃo / Interaction between cyclooxygenase-2 and heme oxygenase-1 / biliverdin / carbon monoxide pathways in nociception and inflammation control in rats and mice.

Introduction: Heme oxygenase-1 (HO-1) plays a preventive role in oxidative stress. In contrast, COX-2 is involved in the pathogenesis of many inflammatory diseases and COX-2 selective inhibition has been shown to be effective in reversing inflammation without gastric side effects. However, serious cardiovascular effects of some selective COX-2 inhibitors eme
