AT-527(Bemnifosbuvir hemisulfate), a hemisulfate salt of AT-511, a guanosine nucleotide proagent, is a potent and orally active HCV viral replication inhibitor. Bemnifosbuvir hemisulfate is highly effective in the control of SARS-CoV-2 (COVID-19) infection in vitro (EC90=0.47 μM). Bemnifosbuvir hemisulfate has pangenotypic antiviral activity[1][2][3].
