Due to the spike protein of the 2019-nCoV virus facilitates the entry of the virus into cells, particularly respiratory epithelial cells, by binding to the angiotensin‐converting enzyme 2 (ACE2) receptor, leading to infection and the development of the disease71–73, we want to explore whether ingredients from Danshen could play inhibition potential in binding to ACE2 and spike protein. Here, ACE2 is linked to infection.
