New progress in research on respiratory syncytial virus inhibitors

Respiratory syncytial virus (RSV) is the main pathogen causing respiratory infections in infants, the elderly, and immunocompromised individuals. Currently, ribavirin and the humanized monoclonal antibody palivizumab are commonly used for lower respiratory tract infections caused by RSV. However, their clinical application has been limited by their efficacy, economy and safety. Therefore, it is necessary to develop new RSV inhibitors to meet the needs of clinical prevention and treatment. This paper selects typical research cases and reviews the research progress of different target inhibitors from the perspective of medicinal chemistry.
