Asymmetric imidazole-4,5-dicarboxamide derivatives as SARS-CoV-2 main protease inhibitors: design, synthesis and biological evaluation.

The SARS-CoV-2 main protease, a vital enzyme for virus replication, is a potential target for developing drugs in COVID-19 treatment. Until now, three SARS-CoV-2 main protease inhibitors have been approved for COVID-19 treatment. This study explored the inhibitory potency of asymmetric imidazole-4,5-dicarboxamide derivatives against the SARS-CoV-2 main protease.
