摘要
Dear Editor,Coronavirus disease 2019(COVID-19)caused by severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)is a major public health issue.The spike(S)protein mutation D614G became dominant in SARS-CoV-2 during a global pandemic,which displayed increased infectivity.1 Entry of a virus into host cells is one of the most critical steps in the viral life cycle.Since blockade of the entry process is a promising therapeutic option for COVID-19,research attention has been focused on the discovery of viral entry inhibitors.Although SARS-CoV-2 entry inhibitor development is very attractive,no candidates have progressed into clinical trials yet.
