Potential Antiviral Compounds for Coronaviruses: Tests and Screenings
- 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.
