In vitro experiments assessing the efficacy of remdesivir and favipiravir against poliovirus.

Structured PICO

Population

HeLa cells infected with Sabin-like poliovirus types 1 (SL1) and 3 (SL3)

Intervention

Remdesivir, Favipiravir, and Ribavirin individually and in combination

Outcome

Antiviral effects measured by cytopathic effect inhibition, MTT assay, and qRT-PCR, and RdRp binding affinitysurrogate

Remdesivir, Favipiravir, and Ribavirin show potential in vitro antiviral activity against poliovirus.

Abstract

Complete poliovirus eradication requires managing chronic excreters and controlling potential outbreaks. RNA-dependent RNA Polymerase (RdRp) inhibitors represent promising candidates for this purpose. The antiviral activities of Remdesivir, Favipiravir, and Ribavirin against Sabin-like poliovirus types 1 (SL1) and 3 (SL3) were evaluated in HeLa cells individually and in combination. Antiviral effects were measured by cytopathic effect inhibition, MTT assay, and qRT-PCR. Drug-drug interactions were analyzed using Synergy Finder Plus. Molecular docking was performed to evaluate RdRp binding affinity. Remdesivir demonstrated the modest activity with low EC
