Parthenolide reveals an allosteric mode to inhibit the delSGylation activity of SARS-CoV-2 papain-like protease
文献摘要:
The coronavirus papain-like protease(PLpro)of severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)is responsible for viral polypeptide cleavage and the delSGylation of interferon-stimulated gene 15(ISG15),which enable it to participate in virus replication and host innate immune pathways.Therefore,PLpro is considered an attractive antiviral drug target.Here,we show that parthenolide,a germacrane sesquiterpene lactone,has SARS-CoV-2 PLpro inhibitory activity.Parthenolide covalently binds to Cys-191 or Cys-194 of the PLpro protein,but not the Cys-111 at the PLpro catalytic site.Mutation of Cys-191 or Cys-194 reduces the activity of PLpro.Molecular docking studies show that parthenolide may also form hydrogen bonds with Lys-192,Thr-193,and Gln-231.Furthermore,parthenolide inhibits the delSGylation but not the deubiquitinating activity of PLpro in vitro.These results reveal that parthenolide inhibits PLpro activity by allosteric regulation.
