Chikungunya virus: an update on antiviral development and challenges

Area of Science:

• Virology
• Infectious Diseases
• Drug Discovery

Background:

• Chikungunya virus (CHIKV) re-emerged as a major public health concern following the 2005 epidemic.
• The lack of approved antiviral therapies necessitates urgent research into CHIKV treatments.

Purpose of the Study:

• To review and analyze the in vitro and in vivo efficacies of antiviral compounds against CHIKV.
• To assess the therapeutic potential of emerging CHIKV antiviral strategies.

Main Methods:

• Literature review of studies reporting anti-CHIKV activity.
• Analysis of compounds targeting host components and viral nonstructural proteins.
• Evaluation of both in vitro and in vivo experimental data.

Main Results:

• A range of potential therapeutics show anti-CHIKV activity in vitro.
• Therapeutic strategies include broad-spectrum antivirals and RNA silencing technology.
• Recent research focuses on targeting viral nonstructural proteins.

Conclusions:

• Intensified research is yielding diverse antiviral approaches for CHIKV.
• Further investigation into the efficacy and potential of these compounds is warranted.
• Development of effective CHIKV antivirals remains a critical medical need.
