Lipopeptide against SARS-COV-2

As the coronavirus SARS-CoV-2 spreads globally, we keep tracking the latest scientific findings and knowledge on the coronavirus and disease (COVID-19). We update this article regularly by searching contents of relevant journals and websites.

Inhibition of SARS-CoV-2 (previously 2019-nCoV) infection by a highly potent pan-coronavirus fusion inhibitor targeting its spike protein that harbors a high capacity to mediate membrane fusion 

Cell Research published the latest research on the X-ray crystal structure of six-helical bundle (6-HB) core of the HR1 and HR2 domains in the SARS-CoV-2 S protein S2 subunit, revealing that several mutated amino acid residues in the HR1 domain. That leads to SARS-CoV-2 showed a superior plasma membrane fusion capacity compared to that of SARS-CoV.

More importantly, they the researchers generated a series of lipopeptides derived from EK1 (the optimized form of OC43-HR2P, showed substantially improved pan-CoV fusion inhibitory activity and pharmaceutical properties) and found that EK1C4 was the most potent fusion inhibitor against SARS-CoV-2 S protein-mediated membrane fusion and pseudovirus infection. learn more
