Cepharanthine: A Promising Old Drug against SARS-CoV-2.

ABSTRACT

Recently, the inhibiting effects of a clinically approved drug Cepharanthine on severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) have attracted widespread attention and discussion. However, the public does not understand the relevant research progress very well. This paper aims to introduce a brief history of studies on the effects of cepharanthine against SARS-CoV-2, including "discovery of anti-SARS-CoV-2 activity of cepharanthine in vitro", "potential mechanisms of cepharanthine against SARS-CoV-2", "confirmation of cepharanthine's anti-SARS-CoV-2 activity in vivo", "potential approaches for improving the druggability of cepharanthine" and "clinical trials of cepharanthine treating SARS-CoV-2 infection". Taken together, cepharanthine is believed to be a promising old drug for coronavirus disease-19 (COVID-19) therapy.
