Recent advances in small-molecule inhibitors targeting influenza virus RNA-dependent RNA polymerase / 药学学报

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.

Recent advances in small-molecule inhibitors targeting influenza virus glycoproteins / 药学学报

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.

Progress on the discovery and development of anti-zika virus agents / 药学学报

Zika virus (ZIKV) is a kind of mosquito-borne flavivirus. ZIKV infection initially shows mild symptoms on patients, but will lead to severe neurological complications (such as Guillain-Barré syndrome) in the end. Meanwhile, pregnant women are sensitive to ZIKV, since the viruses may cause microcephaly. In 2015, after the epidemic in Brazil, ZIKV draws the public attention around the world because of its increased virulence and rapid dissemination. However, there is no approved specific anti-ZIKV drugs at present. This review summarizes progress on anti-zika virus drug research and provides prospects in this field.

Progress on IFV drug targets and small molecule inhibitors / 药学学报

The outbreak of the influenza viruses (IFV) caused significant harm to our health and life. Human infections caused by pathogenic avian influenza virus (AIV) have continually brought great panic and death threats to people all over the world. With the in-depth study of the biological characteristics of influenza viruses and the rapid development of drug discovery screening technology, a new generation of anti-influenza drug targets and their inhibitors have been continuously discovered, providing more options for the treatment of influenza. From the point of view of medicinal chemistry, this review summarizes and discusses current endeavours towards the discovery and development of novel inhibitors and also provides examples illustrating new methodologies that contribute to the identification of novel anti-influenza drugs.
