RESUMEN
Influenza virus causes serious threat to human life and health. Due to the inherent high variability of influenza virus, clinically resistant mutant strains of currently approved anti-influenza virus drugs have emerged. Therefore, it is urgent to develop antiviral drugs with new targets or mechanisms of action. RNA-dependent RNA polymerase is directly responsible for viral RNA transcription and replication, and plays key roles in the viral life cycle, which is considered an important target of anti-influenza drug design. From the point of view of medicinal chemistry, this review summarizes current advances in diverse small-molecule inhibitors targeting influenza virus RNA-dependent RNA polymerase, hoping to provide valuable reference for development of novel antiviral drugs.
RESUMEN
Hemagglutinin and neuraminidase, two important glycoproteins on the surface of influenza virus, play a considerable role in the entry and release stage of the viral life cycle, respectively. With in-depth investigation of influenza virus glycoproteins and the continuous innovation of drug discovery strategies, a new generation of glycoproteins inhibitors have been continuously discovered. From the point of view of medicinal chemistry, this review summarizes the current advances in seeking small-molecule inhibitors targeting influenza virus glycoproteins, hoping to provide valuable guidance for future development of novel antiviral drugs.
