  • Publication number: 20240108737
    Abstract: The present invention relates to multimers of polypeptides which are covalently bound to molecular scaffolds such that two or more peptide loops are subtended between attachment points to the scaffold. The invention also describes the multimerization of polypeptides through various chemical linkers and hinges of various lengths and rigidity using different sites of attachments within polypeptides. In particular, the invention describes multimers of peptides which are high affinity binders of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), particularly the spike protein S1 of SARS-CoV-2. The invention also includes pharmaceutical compositions comprising said polypeptides and to the use of said polypeptides in suppressing or treating a disease or disorder mediated by infection of SARS-CoV-2 or for providing prophylaxis to a subject at risk of infection of SARS-CoV-2.

  • Publication number: 20240083945
    Abstract: The present invention relates to polypeptides which are covalently bound to molecular scaffolds such that two or more peptide loops are subtended between attachment points to the scaffold. In particular, the invention describes peptides which are high affinity binders of the COVID-19 nucleocapsid protein (N-protein). The invention also includes pharmaceutical compositions comprising said polypeptides and to the use of said polypeptides in suppressing or treating a disease or disorder mediated by the COVID-19 nucleocapsid protein (N-protein), such as infection of COVID-19 or for providing prophylaxis to a subject at risk of infection of COVID-19.
