  • Patent number: 7662860
    Abstract: The present invention discloses 3D-structure of SARS-CoV Viral 3CL Protease obtained through molecular simulation. The 3D-structure is used as a drug target for screening the existing medical database CMC (Comprehensive Medicinal Chemistry, MDL Information System, Inc.), and a group of compounds which have the activity of inhibiting SARS-CoV virus 3CL Protease are found. Cinanserin was tested at molecular and viral levels, and it was found to be able to inhibit the SARS-CoV viral 3CL protease and SARS-CoV viruses. Cinanserin analogs were synthesized and tested at molecular and viral levels, they were found to be able to inhibit the SARS-CoV virus 3CL Protease and SARS-CoV viruses, and may be used for treating and/or preventing SARS-CoV virus infection.
