Recent advances in PROTAC-based antiviral and antibacterial therapeutics

By harnessing the ubiquitin proteasome system, proteolysis targeting chimeras (PROTACs) have emerged as a highly promising strategy in drug design for degrading pathogenic proteins. The extensive benefits of PROTAC technology have facilitated its swift and extensive adoption, resulting in numerous PROTACs advancing to clinical trials, and most of them was used for cancers, neurodegenerative diseases, and immune disorders in clinical trials. A number of antiviral PROTACs and antibacterial PROTACs have been developed, exhibiting encouraging bioactivities against various pathogenic viruses and bacterial. Herein, this review summarizes recent advances in PROTAC technology for antiviral and antibacterial drugs, we also provided an overview of the current state of PROTAC clinical trials and detailed the crystal structures of PROTAC in complex with its target protein. Hopefully, this review will contribute to the development of novel antiviral and antibacterial drugs through the utilization of PROTAC technology.
