Structure of the Varicella Zoster Virus Thymidylate Synthase Establishes Functional and Structural Similarities as the Human Enzyme and Potentiates Itself as a Target of Brivudine Varicella zoster virus (VZV) is a highly infectious human herpesvirus that is the causative agent for chicken pox and shingles. VZV encodes a functional thymidylate synthase (TS), which is the sole enzyme that produces using differential scanning fluorimetry (DSF), suggesting that TSVZV binds dUMP and raltitrexed in a sequential binding mode like other TS. The DSF also revealed interactions between TSVZV and in vitro phosphorylated brivudine (BVDUP), a highly potent anti-herpesvirus drug against VZV infections. The binding of BVDUP to TSVZV was further confirmed by the complex structure of TSVZV and BVDUP solved

zoster occurring at the surgical site. A 68-year-old man developed herpes zoster at the surgical site and severe neuralgia following left nephroureterectomy for left kidney clear cell carcinoma accompanied by postoperative renal insufficiency. After treatment with brivudine, the herpes was controlled, and neuralgia began to subside by day 3, with crust formation occurring by day 9. Postoperative nerve injury and regeneration may influence varicella-zoster virus latency. This case indicates that brivudine is an effective treatment for herpes zoster in patients with chronic renal insufficiency.

effectiveness. * Brivudine and foscarnet do not substantially differ in effectiveness from trifluridine or acyclovir. * Ganciclovir is at least as effective as acyclovir.Complications[1] * Corneal scarring and visual impairment this may be progressive and irreversible after recurrent ocular herpes simplex infections. It occurs in 18–28% of cases of stromal keratitis. * Herpes simplex keratitis is the leading

or vidarabine and similar in therapeutic effectiveness. Brivudine and foscarnet do not differ significantly in effectiveness from trifluridine or aciclovir. Ganciclovir is at least as effective as aciclovir. Most patients also benefit from lubricants. Whilst it is best practice to refer the patient with suspected HSV, in a well-established case of recurrent infections, treatment may exceptionally be started

in a surveystudy follow-up of a previously conducted RCT,13which found asignificantly lower incidence of PHN after brivudin than afteraciclovir treatment.18In an RCT comparing brivudin with famci-clovir, however, no statistically significant between-group differ-ences with respect to pain prevalence and duration were seen.19Regarding ocular complications of HZ ophthalmicus, painduration and resolution and placebo inimmunocompromised patients with localized or disseminatedHZ; here, aciclovir was superior considering a reduced incidenceof complications (including cutaneous and visceral dissemina-tion).23Another RCT in 48 immunocompromised patients,comparing intravenous aciclovir with oral brivudin did not findstatistically significant differences regarding cutaneous or vis-ceral dissemination.24When

patterns shared between compounds. As a test case, we took the anti-viral drug brivudine (BVDU), which also has anti-cancer activity, and defined ten interaction patterns using our tool PLIP. These patterns characterise BVDU's interaction with its target s. Using PLIP we performed an in silico screen of all structural data currently available and identified the FDA approved malaria drug amodiaquine

HSV-1 isolates and a fluorescence reporter were introduced into the HSV-1 strain 17(+) that had been cloned into a bacterial artificial chromosome. The susceptibility of these different strains to aciclovir, penciclovir, brivudin, and foscarnet was determined with a modified cytopathic effect reduction assay. The strains were also tested for their aciclovir susceptibility by measuring the relative fluorescence intensity as an indicator for HSV-1 replication and by quantifying the virus yield. Our data indicate that the amino acid substitutions R41H, R106H, A118V, L139V, K219T, S276R, L298R, S345P, and V348I represent natural polymorphisms of the TK protein, whereas G61A and P84L mediate broad cross-resistance against aciclovir, penciclovir, brivudin, and susceptibility to foscarnet. This method allows

of amino acids 7 to 74 aa (Δaa 7 to 74), were associated with resistance against acyclovir (ACV), penciclovir, or brivudine, whereas the L73I substitution and the Pol substitutions T237K and A955T revealed sensitive viral phenotypes. The results were confirmed by quantitative PCR by measuring the viral load under increasing ACV concentrations. In conclusion, analyzing the enzymatic activities

of antivirals currently marketed for the treatment of alpha- and/or betaherpesvirus infections (including acyclovir, ganciclovir, penciclovir, foscarnet, and brivudin), we also investigated the structure-activity relationship of various 5-substituted uridine and cytidine molecules. The antiviral efficacy of nucleoside derivatives bearing substitutions at the 5 position was decreased if the bromovinyl to those of brivudin. Additionally, we selected brivudin- and acyclovir-resistant rhadinoviruses in vitro and characterized them by phenotypic and genotypic (i.e., sequencing of the viral thymidine kinase, protein kinase, and DNA polymerase) analysis. Here, we reveal key amino acids in these enzymes that play an important role in substrate recognition. Our data on drug susceptibility profiles
