Protease inhibitors from Theobroma cacao impair SARS-CoV-2 replication in vitro
SARS-CoV-2 is a newly emerging virus from the Coronaviridae family that has already infected over 700 million people worldwide and killed over 6 million. This virus uses protease molecules to replicate and infect the host, which makes these molecules targets for therapeutic substances to eliminate the virus and treat infected people. Through the protein-protein molecular docking approach, we detected two cystatins from Theobroma cacao, TcCYS3 and TcCYS4, described as papain-like protease inhibitors. These inhibitors decreased SARS-CoV-2 genomic copies without toxicity to Vero cells. There is a need to perform comprehensive studies in relevant animal models and to investigate the action mechanisms of protease inhibitors from Theobroma cacao that control the replication of SARS-CoV-2 in human cells
