Presatovir (GS-5806) is a novel, orally bioavailable RSV fusion inhibitor (mean EC50: 0.43 nM).Presatovir exhibits potent activity against a wide range of RSV A and B clinical isolates (mean EC50: 0.43 nM) [1]. GS-5806 inhibits pre to post triggered conformational changes of RSV F protein, suggesting a possible mechanism for antiviral activity.
