Protease inhibitors as antiviral agents

Area of Science:

• Virology
• Drug Discovery
• Molecular Biology

Background:

• Approved antiviral agents exist, but combination or alternative therapies are often needed.
• Virus-encoded proteases are essential for viral replication, protein processing, and particle assembly.
• These proteases are increasingly recognized as key targets for novel antiviral interventions.

Purpose of the Study:

• To review general features of virus-encoded proteases.
• To highlight recent advances and challenges in developing viral protease inhibitors.
• To discuss specific viral proteases from herpesviruses, retroviruses, hepatitis C virus, and human rhinoviruses.

Main Methods:

• Literature review of scientific publications.
• Analysis of molecular studies on viral protease function.
• Summary of research and development in viral protease inhibitor strategies.

Main Results:

• Viral proteases play a critical role in the viral life cycle.
• Inhibitors targeting these proteases offer potential for new therapeutic strategies.
• Specific examples from herpesvirus, retrovirus, HCV, and HRV protease research are examined.

Conclusions:

• Virus-encoded proteases are validated targets for antiviral drug development.
• Further research into viral protease inhibitors is essential for combating viral infections.
• Combination therapies involving protease inhibitors may enhance treatment efficacy.
