SARS 3CLpro-IN-1 (Compound 3b) is a stereo-specific SARS 3CL protease inhibitor that belongs to the octahydroisochromene scaffold. It demonstrates inhibition against the P1 site imidazole, with an IC50 value of 95 μM [1].
SARS-CoV-2 3CLpro-IN-4 (Compound 5g) is a multifunctional inhibitor of SARS CoV-2 3CLpro, exhibiting antiviral, antibacterial, and antifungal activities.
SARS-CoV-2 3CLpro-IN-1 (Compound 14c) is a highly potent inhibitor specifically designed to target and inhibit the activity of SARS-CoV-2 3CL pro, which is a cysteine-protease found in the main coronaviruses. This particular enzyme has been recognized as a highly promising target for the development of effective antiviral drugs. Therefore, SARS-CoV-2 3CLpro-IN-1 holds significant potential for advancing research and development in the field of infectious diseases [1].
