Emerging drug design strategies in anti-influenza drug discovery

Area of Science:

• Virology
• Drug Discovery
• Infectious Diseases

Background:

• Influenza virus (IFV) causes severe global illness and death, with significant economic and social impacts.
• High mutation rates lead to challenges in vaccine efficacy and antiviral drug resistance.
• Urgent need exists for broad-spectrum antiviral agents effective against current and future IFV strains.

Purpose of the Study:

• To review general strategies for discovering and developing antiviral agents targeting multiple IFV strains.
• To highlight approaches effective against both wild-type and drug-resistant IFV.
• To provide a framework for developing novel anti-IFV therapeutics.

Main Methods:

• Structure-based drug design
• Mechanism-based drug design
• Multivalent interaction-based drug design
• Drug repurposing

Main Results:

• Identified key strategies for antiviral drug development against IFV.
• Emphasized the importance of targeting multiple IFV strains, including resistant ones.
• Highlighted the potential of structure-based, mechanism-based, multivalent, and repurposed drugs.

Conclusions:

• Several promising strategies exist for developing effective anti-influenza virus drugs.
• These approaches offer a framework to address challenges posed by IFV mutation and resistance.
• Continued research in these areas is vital for global influenza preparedness.
