This article is a Preprint
Preprints are preliminary research reports that have not been certified by peer review. They should not be relied on to guide clinical practice or health-related behavior and should not be reported in news media as established information.
Preprints posted online allow authors to receive rapid feedback and the entire scientific community can appraise the work for themselves and respond appropriately. Those comments are posted alongside the preprints for anyone to read them and serve as a post publication assessment.

ABSTRACT
Background Traditional Chinese medicine (TCM) has potential benefits to prevent multi-viral infection including by modulating the immune system or defending oxidative stress. Artemisia argyi (A. argyi) has been widely used for anti-microbial infection, anti-allergy, anti-diabetes, and anti-inflammation in Eastern Asia. However, it remain unclear whether A. argyi has the potential to reduce the infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).Results Through the docking simulation, eriodictyol and umbelliferone, two phytochemicals existed in Artemisia argyi, have showed their potential to bind to cellular proteins transmembrane serine protease 2 (TMPRSS2) and angiotensin-converting enzyme 2 (ACE2), which are required for the cellular entry of SARS-CoV-2. Our results further found that eriodictyol and umbelliferone suppressed the infection of ACE2-expressed HEK-293T cells with lentiviral-based pseudo-particles expressing wild type and variants of SARS-CoV-2 spike (S) protein via interrupting the interaction between S protein and cellular receptor ACE2 and via reducing ACE2 and TMPRSS2 expressions.Conclusions In summary, Artemisia argyi and its ingredients eriodictyol and umbelliferone are potential agents to reduce SARS-CoV-2 infection.
