Abstract: Coronavirus disease 2019 (COVID-19) is a global infectious disease that seriously endangers human life and health and affects normal social activities. Since the pandemic outbreak from December 2019 to February 2023, the total number of confirmed cases has exceeded 753 million, and the deaths caused by COVID-19 have reached 6.6 million (https://covid19.who.int; accessed on Feb. 16, 2023). Currently, supportive therapy is the primary treatment for patients, as some antiviral drugs have demonstrated significant side effects during clinical treatment. Although vaccination has a particular effect on the prevention of novel coronavirus infection and the emergence of severe diseases, the variation in the virus strain caused the vaccine’s protective effect to be greatly weakened or lost. Therefore, there is an urgent need to identify safe and effective drugs to prevent and cure COVID-19. Relevant research and exploration can also provide a reference for drug screening with which to address similar infectious diseases and public health events in the future.
