RESUMO
Over the course of human civilization, viral infections have been a part of human life and still represent one of the heaviest burdens for human and society, with a huge devastating socioeconomic impact. Inorganic and bioinorganic chemistry have made important contributions to medical science and human health in the past half century. In this paper, we selected the representative cases in recent years, and reviewed the research progress of antiviral drug discovery from the perspective of bioinorganic chemistry.
