Patent

CA 2407086

The present invention concerns fusion of half-life extending vehicles, preferably Fc domains, with peptide sequences that act as antagonists of integrins, selectins, cell adhesion molecules, or their respective receptors. Linkage to the vehicle increases the half-life of the peptide, which otherwise would be quickly degraded in vivo. The peptide may be an existing peptide or a peptide selected by phage display, E. coli display, ribosome display, RNA- peptide screening, chemical-peptide screening, or other methods.

La présente invention concerne la fusion d'excipients, de préférence des domaines Fc, qui allongent la demi-vie avec des séquences peptidiques qui agissent comme antagonistes des intégrines, des sélectines, des molécules d'adhésion de cellules, ou de leurs récepteurs respectifs. La liaison à l'excipient augmente la demi-vie du peptide, qui autrement serait rapidement dégradé in vivo. Le peptide peut être un peptide existant ou un peptide sélectionné par l'expression phagique, l'expression dans E. coli, par une chimiothèque de ribosomes, par criblage par liaison ARN-peptides, par criblage par peptides d'origine chimique ou par d'autres méthodes.
