英文摘要 | Although the effective drugs or vaccines have been developed to prevent the spread of the severe acute respi-ratory syndrome coronavirus 2 (SARS-CoV-2), their efficacy may be limited for the viral evolution and immune escape. Thus, it is urgently needed to develop the novel broad-spectrum antiviral agents to control the coro-navirus disease 2019 (COVID-19) global pandemic. The 3C-like protease (3CLpro) is a highly conserved cysteine proteinase that plays a pivotal role in processing the viral polyprotein to create non-structural proteins (nsps) for replication and transcription of SARS-CoV-2, making it an attractive antiviral target for developing broad-spectrum antiviral agents against SARS-CoV-2. In this study, we identified Thonzonium bromide as an inhibi-tor of SARS-CoV-2 3CLpro with an IC50 value of 2.04 +/- 0.25 mu M by fluorescence resonance energy transfer (FRET)-based enzymatic inhibition assay from the FDA-approved drug library. Next, we determined the inhib-itory activity of Thonzonium bromide analogues against SARS-CoV-2 3CLpro and analyzed their structur-e-activity relationship (SAR). Interestingly, Thonzonium bromide showed better inhibitory activity than other analogues. Further fluorescence quenching assay, enzyme kinetics analysis, circular dichroism (CD) analysis and molecular docking studies showed that Thonzonium bromide inhibited SARS-CoV-2 3CLpro activity by firmly occupying the catalytic site and inducing conformational changes of the protease. In addition, Thonzonium bromide didn't exhibit inhibitory activity on human chymotrypsin C (CTRC) and Dipeptidyl peptidase IV (DPP -IV), indicating that it had a certain selectivity. Finally, we measured the inhibitory activities of Thonzonium bromide against 3CLpro of SARS-CoV, MERS-CoV and HCoV-229E and found that it had the broad-spectrum inhibitory activity against the proteases of human coronaviruses. These results provide the possible mecha-nism of action of Thonzonium bromide, highlighting its potential efficacy against multiple human coronaviruses. |
