SHEN-211 is a selective 3-chymotrypsin-like protease (3CLpro) inhibitor that can protect against SARS-CoV-2. In previous work, SHEN-211 demonstrated high efficacy in inhibiting 3CLpro (IC50=24 nM) and exhibited broad-spectrum antiviral properties.
Although safe and effective vaccines for SARS-CoV-2 have been successfully developed, there are currently no therapeutic approaches available for treating acute infection, particularly for individuals at high risk of severe disease progression, and for preparedness against a potential new coronavirus pandemic.
Shanghai Curegene Pharmaceutical Co. Ltd. has synthesized 3C-like proteinase (3CLpro; Mpro; nsp5) (SARS-CoV-2; COVID-19 virus) inhibitors reported to be useful for the treatment of SARS-CoV-2 infections (COVID-19).
Shionogi & Co. Ltd. won a $375 million project agreement from the Rapid Response Partnership Vehicle to develop its 3CL protease inhibitor, S-892216, as a long-acting injectable for COVID-19 pre-exposure prophylaxis. The project was awarded to New Jersey-based Shionogi Inc., a subsidiary of the Osaka, Japan-based pharmaceutical company. S-892216 is an investigational second-generation 3CL protease inhibitor in development as a long-acting injectable for prophylaxis treatment of SARS-CoV-2.

The Agency for Science Technology & Research (A*STAR) Bioprocessing Technology Institute has patented 3C-like proteinase (3CLpro; Mpro; nsp5) (coronavirus) inhibitors.
Westlake Pharmaceutical (Hangzhou) Co. Ltd. has prepared and tested new 3C-like proteinase (3CLpro; Mpro; nsp5) inhibitors reported to be useful for the treatment of coronavirus acute respiratory syndrome.
Tohoku University has disclosed 3C-like proteinase (3CLpro; Mpro; nsp5) (SARS-CoV-2; COVID-19 virus) inhibitors reported to be useful for the treatment of viral infections and inflammatory disorders.
In work at Shanghai Curegene Pharmaceutical Co. Ltd., synthesis and optimization of a series of SARS-CoV-2 3CL protease (3CLpro, Mpro) inhibitors led to the identification of compounds [I], [II] and [III] as lead candidates suitable for further evaluation, based on their enzymatic IC50s (14, 12 and 8.6 nM, respectively), cellular EC50s (36, 26 and 52 nM, respectively) and human liver microsome (HLM) stability.
Merck Sharp & Dohme LLC has disclosed 3C-like proteinase (3CLpro; Mpro; nsp5) (SARS-CoV-2; COVID-19 virus) inhibitors reported to be useful for the treatment of SARS-CoV-2 infection (COVID-19).
