HIV-1 Protease Inhibitor ASC09 is an orally bioavailable human immunodeficiency virus type 1 (HIV-1) protease inhibitor, with potential activity against HIV and certain other RNA viruses. Upon oral administration, HIV-1 protease inhibitor ASC09 selectively targets and binds to the active site of HIV-1 protease, and inhibits the dimerization and catalytic activity of HIV-1 protease. This inhibits the proteolytic cleavage of viral Gag and Gag-Pol polyproteins in HIV-infected cells. This inhibition leads to the production of immature, non-infectious viral proteins that are unable to form mature virions, and prevents HIV replication. In addition, ASC09 may also inhibit viral proteases from other RNA viruses, thereby preventing their replication.
