Area of Science:

  • Virology
  • Infectious Diseases
  • Drug Discovery

Background:

  • Respiratory syncytial virus (RSV) causes severe illness in vulnerable populations.
  • RSV vaccine and drug development are hindered by virus instability.
  • Existing antiviral assays lack robustness for high-throughput screening.

Purpose of the Study:

  • To develop and validate a stable, cell-based high-throughput screening assay for RSV inhibitors.
  • To overcome the challenge of virus instability in RSV research.
  • To facilitate efficient drug discovery for RSV.

Main Methods:

  • Utilized frozen RSV-infected cells as a source of infectious material.
  • Developed a cell-based assay to screen for inhibitors of RSV-induced cytopathic effect.

High-throughput Antiviral Assays to Screen for Inhibitors of Zika Virus Replication

Published on: October 30, 2021

  • Validated the assay using 1,280 compounds previously identified as potentially active against RSV.
  • Main Results:

    • Successfully overcame the problem of virus instability using infected cells.
    • Validated a robust cell-based high-throughput screening assay for RSV.
    • Screened over 300,000 compounds with minimal variability in controls over several months.

    Conclusions:

    • The developed cell-based assay is stable and suitable for high-throughput screening.
    • This assay provides a viable platform for identifying novel RSV antiviral drugs.
    • The method addresses a critical limitation in RSV drug discovery research.
