GtoPdb Ligand ID: 12043

Compound class: Synthetic organic
Comment: This compound is one of the SARS-CoV-2 main protease (Mpro) inhibitors claimed in patent WO2021252491A1 from Aligos Therapeutics and Katholieke Universiteit Leuven [2]. We selected this example (58) for its combination of potency against SARS-CoV-2 Mpro enzymatic activity, and its ability to inhibit SARS-CoV-2 infection with relatively low cytotoxicity against model cell lines in vitro. Aligos Therapeutics have declared ALG-097558 as their lead clinical candidate SARS-CoV-2 antiviral, but have not yet disclosed its chemical structure (June 2022). Aligos have also published in vitro data (inhibition of SARS-CoV-2 infection in the Syrian hamster model) for another Mpro inhibitor, ALG-097111 [1], but again no complete chemical structure was divulged.
