TimTec Natural Product Library was screened to identify compounds that significantly reduce infectivity without cytotoxicity. NPL collection counted 280 compounds at the time of the moderate-throughput screening. MTS assay is adaptable to different virus systems.
Out of 280 compounds, 15 molecules showed antiviral activity and were identified as promising models for immunomodulatory agents.
