  • MODIFIED ANGIOTENSIN-CONVERTING ENZYME 2 (ACE2) AND USE THEREOF
    Publication number: 20230193235
    Abstract: The modified polypeptides include at least one amino acid substitution that allows the polypeptide to bind better to the S surface glycoprotein of coronaviruses that use ACE2 as a cell entry receptor, either through direct increases in affinity or through improved folding and expression of ACE2. Use of the modified ACE2 polypeptides for inhibiting CoV entry, replication and/or spread, for pre-exposure and post-exposure CoV prophylaxis, and for treating a CoV infection (e.g. COVTD-19), is also described.
