The mechanism and pharmacodynamics of 2-((1H-indol-3-yl)thio/sulfinyl)-N-pheny acetamide derivative as a novel inhibitor against human respiratory syncytial virus.

Human respiratory syncytial virus (RSV) is a leading cause of lower respiratory tract infection worldwide. Until now, there are no licenced vaccines or effective antiviral drugs against RSV infections. In our previous work, we found 2-((1H-indol-3-yl)thio/sulfinyl)-N-pheny acetamide derivatives (4-49 C and 1-HB-63) being a novel inhibitor against RSV .

Design and synthesis of 2-((1H-indol-3-yl)thio)-N-phenyl-acetamides as novel dual inhibitors of respiratory syncytial virus and influenza virus A.

Respiratory syncytial virus (RSV) and influenza A virus (IAV) are two of the most common viruses that cause substantial morbidity and mortality in infants, young children, elderly persons, and immunocompromised individuals worldwide. Currently, there are no licensed vaccines or selective antiviral drugs against RSV infections and most IAV strains become resistant to clinical anti-influenza drug. Here, we described the discovery of a series of 2-((1H-indol-3-yl)thio)-N-phenyl-acetamide as novel and potent RSV and IAV dual inhibitors.

High-throughput screening of active compounds against human respiratory syncytial virus.

Human respiratory syncytial virus (RSV) is one of the predominant pathogens causing lower respiratory tract infection in infants and young children worldwide, whereas there is so far no vaccine or drug against RSV infection for clinical use. In this work, we developed and validated a fluorescence-based high-throughput screening (HTS) assay to identify compounds active against RSV, using RSV-mGFP, a recombinant RSV encoding enhanced green fluorescent protein (EGFP). Thereafter, among 54,800 compounds used for our screen, we obtained 62 compounds active against RSV.
