ABSTRACT

Introduction: Chikungunya virus (CHIKV), a reemerging human arthropod borne virus, can causes global epidemic outbreaks and has become a serious health concern due to the unavailability of any antiviral therapy/vaccine. Extensive research has been conducted to target different proteins from CHIKV to curtail the spread of virus.

Areas covered: This review provides an overview of the granted patents including the current status of antiviral strategies targeting CHIKV.

Expert opinion: Under the current scenario, potential molecules and different approaches have been utilized to suppress CHIKV infection. MV-CHIKV and VRC-CHKVLP059-00-VP vaccine candidates have successfully completed phase I clinical trials and ribavirin (inhibitor) has shown significant inhibition of CHIKV replication and could be the most promising candidates. The drug resistance and toxicity can be modulated by using the inhibitors/drugs in combination. Moreover, nanoparticle formulations can improve the efficacy and bioavailability of drugs.

Article highlights

  • Global CHIKV epidemic warrants the identification of drug candidates.

  • Inhibitors/drugs, monoclonal antibodies, virus-like particles and siRNAs are being studied for effective inhibition of CHIKV.

  • Combinational drugs can improve efficacy and reduce the incidence of resistance.

  • Nano-based formulations of drugs can enhance stability and bioavailability.
