Combating enterovirus replication: state-of-the-art on antiviral research

Area of Science:

• Virology
• Antiviral drug development

Background:

• Enteroviruses are significant human and veterinary pathogens within the Picornaviridae family.
• Despite their impact, no approved antiviral therapies are currently available for enterovirus infections.

Purpose of the Study:

• To review existing antiviral inhibitors targeting enteroviruses.
• To identify and discuss potential viral and cellular targets for novel antiviral therapies.

Main Methods:

• Literature review of existing and developing antiviral agents.
• Analysis of viral replication cycles and host-pathogen interactions.
• Identification of potential drug targets within viral proteins and host cell factors.

Main Results:

• Capsid-targeting molecules like pleconaril show promise but face limitations such as resistance and species-specific activity.
• Viral proteins (3C protease, 2C helicase, 3D RNA polymerase) and host factors are identified as potential therapeutic targets.
• Understanding virus-host interactions is crucial for developing effective antivirals.

Conclusions:

• Developing antivirals targeting different stages of the viral replication cycle is essential.
• Novel therapeutic strategies are needed to overcome limitations of current capsid inhibitors.
• Further research into viral and cellular targets holds promise for future enterovirus treatments.
