Antiviral drug, any agent used in the treatment of an infectious disease caused by a virus. Antiviral agents generally are designed to block viral replication or disable viral proteins. Examples of antiviral drugs include agents to combat herpes viruses,
4.1. General mechanism of action The mechanisms of antiviral drugs action are mainly acting on the virus itself or acting on the host. Also, antiviral drugs act on various enzymes related to transcription and replication to destroy the viral pathogen or inactivate its infectivity (Vilas Boas et ...
susceptibility to disinfectants or mode of replication. Typically, a virus will be surrounded by a protective protein layer—capsid. Capsids are formed in a highly specific manner and their function is to protect the viral genome8. There are three main types of capsid shape: icosahedral, helical...
The Infectious Diseases Society of America (IDSA) states that antiviral drugs should not be used for routine or widespread chemoprophylaxis outside of institutional outbreaks, but may be considered in certain situations (e.g., patients at high risk of developing complications from influenza). If ...

Mechanism of action of antiviral EOs and EO compounds Until now, very few studies have demonstrated the mode of action of EOs on viruses. Most of the studies predicted that the EOs could interfere with the virion envelope structure or mask the virus structure, which subsequently blocks the virus...

We demonstrate that Ci extracts show broad inhibitory activity against different HIV isolates, including a clinical virus isolate with multiple resistances against conventional drugs. Mode-of-action studies demonstrate that Ci extracts target viral envelope proteins, preventing the primary attachment of the...
main ways. The action of the antibody variable region binding to the virus alone may mediate neutralisation by directly preventing completion of the viral life cycle, but in many cases, the Fc region functions as well. This is due to the interaction of the Fc region of intracellular antibodies...
