Biological Activity

NBCoV1 is a highly potent small molecule viral fusion inhibitor with potential pan-Coronavirus activity (SARS-CoV IC50=17 nM, SARS-CoV-2 IC50=51 nM, MERS-CoV IC50=75 nM, cell-based single-cycle assays).
NBCoV1 also has potent antiviral activity against all mutant pseudoviruses carrying single-, double-, or triple-mutations featured in the B.1.1.7 UK, B.1.351 RSA, and B.1.617.2 Delta variants (IC50=30-80 nM).
NBCoV1 completely preventing the induction of any virus-induced CPE (IC100=1.25 uM, SARS-CoV-2 (US_WA-1/2020)).
NBCoV1 bind to the S2 subdomain of the SARS-CoV-2 trimer, thus, inhibits the fusion of CoVs with the cell membran, and is specific for the SARS-CoV-2 S protein.
NBCoV1 demonstrated drug-like properties, excellent half-life (t1/2) of 11.3 h, a mean resident time (MRT) of 14.2 h, and oral bioavailability.
