Potential Antiviral Compounds for Coronaviruses: Tests and Screenings

Potential Antiviral Compounds for Coronaviruses: Tests and Screenings

(From Potential Antiviral Agents for Coronaviruses: Compounds, Herbal Products, and Drug Targets)

  • Some agents inhibiting coronaviral replication have been investigated (Golda and Pyrc, 2008).
  • The potential antiviral agents include (Golda and Pyrc, 2008):
    • Carbohydrate-binding agents;
    • Neutralizing antibodies;
    • Drugs targeting the coronaviral envelope protein.
  • Real-time PCR has been used for testing antivirals against Lassa virus, SARS coronavirus, and Ebola virus (Günther et al., 2004).
  • A small-scale screening found a class of imidazole nucleoside/nucleotide analogues with antiviral activities against Lassa virus.
  • The analogues had dinitrile or diester groups at the imidazole 4,5-positions (Günther et al., 2004).
  • Many of these had an acyclic sugar or sugar phosphonate moiety at the imidazole 1-position.
  • The compounds also suppressed the replications of SARS and Ebola viruses (Günther et al., 2004).
  • These compounds may be useful for the development of broad-spectrum drugs against viruses.
