A high-throughput screen identified adamantane dipeptide 1 as an inhibitor of Ebola virus (EboV) infection. Hit-to-lead optimization to determine the structure-activity relationship (SAR) identified the more potent EboV inhibitor 2 and a photoaffinity labeling agent 3. These antiviral compounds were employed to identify the target as Niemann-Pick C1 (NPC1), a host protein that binds the EboV glycoprotein and is essential for infection. These studies establish NPC1 as a promising target for antiviral therapy.
