Antiviral activity of R1479, 2″F-4′N3-C, and 2′diF-4′N3-C against reporter pneumo- and paramyxoviruses. Representative dose response curves for R1479 (green circles), 2′F-4′N3-C (blue triangles), and 2′diF-4′N3-C (red squares) against recombinant reporter (a) respiratory syncytial virus (rgRSV224), (b) measles virus (rMVEZ(3)GFP), (c) human parainfluenza virus 3 (hPIV3-GFP), and (d) Nipah virus (NiV-GFP2AM). Data points and error bars indicate the mean value and standard deviation of 4 biological replicates, and are representative of at least 2 independent experiments for each compound.
