Biological Activity

ST-193 (ST193) is a potent, selective, broad-spectrum arenavirus entry inhibitor with IC50 of 1.6 nM against LASV pseudotypes, targets arenavirus envelope glycoprotein.
ST-193 also inhibits pseudotypes generated with other arenavirus envelopes with IC50 of 0.2-12 nM, but exhibited no antiviral activity against pseudotypes incorporating either the GP from the LASV-related arenavirus LCMV or the unrelated G protein from vesicular stomatitis virus (IC50>10 uM).
ST-193 exhibits antiviral activity against Lassa virus (LASV) in a guinea pig model (i.p.).
