Abstract

At the time of writing, more than 440 million confirmed coronavirus disease 2019 (COVID-19) cases and more than 5.97 million COVID-19 deaths worldwide have been reported by the World Health Organization since the start of the outbreak of the pandemic in Wuhan, China. During the COVID-19 pandemic, many variants of SARS-CoV-2 have arisen because of high mutation rates. N501Y, E484K, K417N, K417T, L452R and T478K in the receptor binding domain (RBD) region may increase the infectivity in several variants of SARS-CoV-2. In this study, we discovered that GB-1, developed from Chiehyuan herbal formula which obtained from Tian Shang Sheng Mu of Chiayi Puzi Peitian Temple, can inhibit the binding between ACE2 and RBD with Wuhan type, K417N-E484K-N501Y and L452R-T478K mutation. In addition, GB-1 inhibited the binding between ACE2 and RBD with a single mutation (E484K or N501Y), except the K417N mutation. In the compositions of GB-1, glycyrrhizic acid can inhibit the binding between ACE2 and RBD with Wuhan type, except K417N-E484K-N501Y mutation. Our results suggest that GB-1 could be a potential candidate for the prophylaxis of different variants of SARS-CoV-2 infection because of its inhibition of binding between ACE2 and RBD with different mutations (L452R-T478K, K417N-E484K-N501Y, N501Y or E484K).
