| Description | YM-53403 is an antiviral activity that effectively inhibits the replication of RSV strains belonging to subgroup A and subgroup B. It can be used to treat respiratory syncytial virus infections. |
| In vitro | YM-53403 (0.2 μM) reduced plaque with EC50 was 0.20 ± 0.05 μM.[2] YM-53403 (50 μM) inhibited the life cycle of RSV at around 8 h post-infection in time-dependent, suggesting an inhibitory effect on early transcription and/or replication of the RSV genome. YM-53403 is an attractive compound for the treatment of RSV infection because of its highly potent anti-RSV activity and the new mode of action.[2] |
