Tilorone, a Broad-Spectrum Antiviral for Emerging Viruses

Tilorone is a 50-year-old synthetic small-molecule compound with Antiviral activity that is proposed to induce interferon after oral administration. This drug is used as a broad-spectrum Antiviral in several countries of the Russian Federation. We have recently described activity in vitro and in vivo against the Ebola virus. After a broad screening of additional viruses, we now describe in vitro activity against Chikungunya virus (CHIK) and Middle Eastern respiratory syndrome coronavirus (MERS-CoV).
