Computational design of ACE2-based short peptide inhibitors of SARS-CoV-2


Peptide inhibitors against the SARS-CoV-2 coronavirus, currently causing a worldwide pandemic, are designed and simulated. The inhibitors are formed by two sequential self-supporting alpha-helices (bundle) extracted from the protease domain (PD) of angiotensin-converting enzyme 2 (ACE2), which binds to the SARS-CoV-2 receptor binding domains. Molecular dynamics simulations revealed that the peptides maintain their secondary structure and provide a highly specific and stable binding (blocking) to SARS-CoV-2, determined by their sequences and conformations. The proposed peptide inhibitors could provide simple therapeutics against the COVID-19 disease.
