SARS-CoV抑制剂;SARS-CoV Inhibitors;;InformationPF-00835231 PF-00835231 is a 3CL pro (M pro ) inhibitor that may targets SARS-CoV-2 protease 3CL pro as a potential new treatment for COVID-19.Targets3CLproIn vitroA time-of-drug-addition approach delineates the timing of early SARS-CoV-2 life cycle steps in A549+ACE2 cells and validates PF-00835231\'s early time of action. In a model of the human polarized airway epithelium, PF-00835231 potently inhibits SARS-CoV-2 at low micromolar concentrations. PF-00835231 exhibits the potential as an effective SARS-CoV-2 antiviral.Cell Research(from reference)Cell lines:A549 cells, human airway epithelial cultures (HAEC) Concentrations:1 nM-10 μM Incubation Time:0-4 h
