چکیده

We previously reported several new M2 inhibitors as active as amantadine against influenza A virus and validated by three types of in vitro assays. Herein, we further modified one of the most potent hits in a viral inhibition assay and conducted structure-activity relationship studies on this scaffold. As a result, compound 8e was identified to be the most potent inhibitor against wild-type influenza A virus, being nearly 240-fold more active than amantadine.

New Anti-Influenza Agents: Targeting the Virus Entry and Genome Transcription

Introduction: The emergence and spread of the pandemic H1N1 influenza virus in 2009 indicates a limitation in the strategy to control the infection, despite a long-established vaccination programme and approved antivirals. Production the proper vaccine against influenza is difficult due to the genetic recombination of virus in the event of pandemic and co-circulation of drug-resistance variants...

Expression of HA1 antigen of H5N1 influenza virus as a potent candidate for vaccine in bacterial system

The impending influenza virus pandemic requires global vaccination to prevent large-scale mortality and morbidity, but traditional influenza virus vaccine production is too slow for rapid responses. In this study, bacterial system has been developed for expression and purification of properly folded HA1 antigen as a rapid response to emerging pandemic strains. Here, a recombinant H5N1 (A/Indone...

The Combined Use of rHVT-H5 and rHVT-F Vector Vaccines in the Hatchery Enhances Immunity against Highly Pathogenic Avian Influenza H5N1 and Velogenic Newcastle Disease Viral Infections in Commercial Chickens

Highly pathogenic avian influenza H5N1 and Newcastle disease viral infections cause severe illness in chickens and vaccination is a strategic tool of controlling these diseases. Hence, this study was conducted to evaluate the efficacy of using both recombinant herpesvirus of turkey (rHVT-H5 and rHVT-F) vector vaccines at day-old, in the hatchery, under field conditions. Vaccinated chickens were...

A novel family of peptides with potent activity against influenza A viruses.

The emergence of drug-resistant strains of influenza virus has catalysed a search for new antiviral agents to supplement or replace existing drugs. Following the success of the human immunodeficiency virus entry blocker Enfuvirtide, there has been a resurgence of interest in peptide-based antivirals. In this paper, we report on the discovery of a novel family of peptides (FluPep, FP) that funct...
