Remdesivir, a monophosphoramidate prodrug of an adenosine analog, is an investigational broad-spectrum antiviral agent with in vitro activity against multiple RNA viruses, including Ebola and CoV.

Chemical name: L-Alanine, N-[(S)-hydroxyphenoxyphosphinyl]-, 2-ethylbutyl ester, 6-ester with 2-C-(4-aminopyrrolo[2,1-f][1,2,4]triazin-7-yl)-2,5-anhydro-D-altrononitrile

Formula: C27H35N6O8P

Storage: 3 years -20°C powder, 2 years -80°C in solvent

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]
