Inhibitors of virus replication: recent developments and prospects

Area of Science:

• Virology
• Molecular Biology
• Drug Discovery

Background:

• Viral replication involves complex molecular events, with each stage presenting potential targets for antiviral interventions.
• Current antiviral strategies often target DNA replication (herpesviruses), reverse transcriptase (HIV), or protease enzymes (HIV, HCV, rhinovirus).
• Emerging targets include virus entry mechanisms and virus release processes, with new anti-influenza drugs exemplifying this approach.

Purpose of the Study:

• To review the molecular targets and strategies for developing antiviral inhibitors.
• To highlight both established and emerging targets within the viral life cycle for drug development.
• To identify under-exploited stages of viral replication as potential avenues for novel antiviral therapies.

Main Methods:

• Literature review of viral replication mechanisms and current antiviral drug targets.
• Analysis of established antiviral drug classes and their mechanisms of action.
• Identification and discussion of novel and underexplored viral targets.

Main Results:

• Viral DNA replication, reverse transcriptase, and proteases are well-established targets for antiviral drug development.
• Virus entry and release are increasingly recognized as critical targets for new antiviral agents.
• Viral RNA capping and replication complex membrane association represent underexplored targets.

Conclusions:

• A comprehensive understanding of viral molecular biology is essential for effective antiviral drug discovery.
• Targeting diverse stages of the viral life cycle, including entry and release, is crucial for combating viral infections.
• Further research into less-characterized viral processes may yield novel therapeutic strategies against a broad spectrum of viruses.
