The antiviral activity of 9-(4-hydroxy-3-hydroxymethylbut-1-yl)guanine (BRL 39123) was assessed in several animal models of herpes simplex virus (HSV) infection. BRL 39123 was as active as acyclovir (ACV) when applied topically to guinea pigs with a cutaneous HSV type 1 (HSV-1) infection and was also active topically in an HSV-2 genital infection. Before systemic administration to infected anim...
Herpes simplex virus (HSV) infections are very common in the general population and among immunocompromised patients. Acyclovir (ACV) is an effective treatment which is widely used. We deemed it essential to conduct a wide and coordinated survey of the emergence of ACV-resistant HSV strains. We have formed a network of 15 virology laboratories which have isolated and identified, between May 199...
The immunosuppressive agent mycophenolate mofetil (MMF) has been approved for use in kidney transplant recipients and may thus be used concomitantly for the treatment of intercurrent herpesvirus infections with drugs such as acyclovir (ACV), ganciclovir (GCV), and penciclovir (PCV). We found that MMF and its parent compound mycophenolic acid (at concentrations that are attainable in plasma) str...
BACKGROUND Acyclovir (ACV) given to HSV-2 positive women after 36 weeks reduces adverse outcomes but its benefit at lower gestation was undocumented. We determined the effect of oral acyclovir administered from 28 to 36 weeks on premature rupture of membranes (PROM) primarily and preterm delivery risk. METHODS This was a randomized, double-blind placebo-controlled trial among 200 HSV-2 positi...
1Department of Pharmaceutics AlAmeen College of Pharmacy Near Lalbagh Main Gate, Hosur RoadBangalore560027,India A b s t r a c t Acyclovir (ACV) is an antiviral drug, used for treatment of herpes simplex virus infections with an oral bioavailability of only 10 to 20 % (limiting absorption in GIT to duodenum and jejunum),half-life about 3 hrs, soluble at acidic pH (pKa 2.27) and distilled water ...
Varicella zoster virus (VZV) is usually associated with mild to moderate illness in immunocompetent patients. However, older age and immune deficiency are the most important risk factors linked with virus reactivation and severe complications. Treatment of VZV infections is based on nucleoside analogues, such as acyclovir (ACV) and its valyl prodrug valacyclovir, penciclovir (PCV) as its prodru...
2-Phenylamino-6-oxo-9-(4-hydroxybutyl)purine (HBPG) is a thymidine kinase inhibitor that prevents encephalitic death in mice caused by herpes simplex virus (HSV) types 1 and 2, although its potency is somewhat less than that of acyclovir (ACV). The present study was undertaken to determine the effect of combinations of HBPG and either ACV, phosphonoformate (PFA), or cidofovir (CDF) against HSV ...
This study investigated the oral bioavailability and efficacy of BILS 45 BS, a selective herpes simplex virus (HSV) helicase-primase inhibitor, against acyclovir (ACV)-resistant (ACV(r)) infections mediated by the HSV type 1 (HSV-1) dlsptk and PAA(r)5 mutant strains. In vitro, the compound was more potent than ACV against wild-type clinical and laboratory HSV-1 strains and ACV(r) HSV isolates, ...
Acyclovir (ACV) is a promising candidate for drug repurposing because of its potential to provide an effective treatment viral infections and non-viral diseases, such as cancer, which limited options exist. However, poor physicochemical properties limit application. This study aimed formulate evaluate ACV-loaded red clay nanodrug delivery system exhibiting cytotoxicity. The focused on the prepa...
To evaluate the effect of acyclovir (ACV) therapy on the cellular immune response, we sequentially followed 43 patients with culture-proven first episodes of genital herpes simplex virus (HSV) infection. Twenty-three patients who were treated with ACV and 20 who received placebo had blood obtained weekly during the first 6 weeks after onset of lesions and had their in vitro lymphocyte transform...
