In vitro:
GS-5734 exhibits antiviral activity against multiple variants of EBOV in cell-based assays(EC50=0.06-0.14 μM) and broad-spectrum antiviral activity in vitro against other pathogenic RNA viruses. [1]GS-5734 acts as a broad-spectrum therapeutic to protect against CoVs with EC50 of 0.03 μM for murine hepatitis virus in delayed brain tumor cells and 0.074 μM for SARS-CoV and MERS-CoV in HAE cells.[2]
In vivo:
Regardless of the time of initiation, GS-5734 treatment confers improved survival when administered by 3 mg/kg GS-5734. All animals in which 10 mg/kg GS-5734 treatments is initiated 3 days after virus exposure survive to the end of the in-life phase. However, the antiviral effects are consistently greater in animals administered repeated 10 mg/kg GS-5734 doses. The 10 mg/kg D3 (administered beginning 3 days after virus exposure) GS-5734 regimen is associated with amelioration of EVD-related clinical disease signs and markers of coagulopathy and end organ pathophysiology.[1]
