Bio-reduction of Redox-Sensitive Albumin Conjugates in FcRn-Expressing Cells

Disulfide‐containing IgG‐, Fc‐, or albumin‐based prodrugs that rely on FcRn‐trafficking by endothelial cells for prolonged circulation in the body might be hampered by premature bio‐reduction processes during FcRn‐mediated recycling events. A detailed bio‐reduction analysis of redox‐sensitive albumi...

description Disulfide‐containing IgG‐, Fc‐, or albumin‐based prodrugs that rely on FcRn‐trafficking by endothelial cells for prolonged circulation in the body might be hampered by premature bio‐reduction processes during FcRn‐mediated recycling events. A detailed bio‐reduction analysis of redox‐sensitive albumin conjugates in two FcRn‐expressing cell lines has been performed. The obtained results indicate that the FcRn‐mediated recycling pathway is not (or is only poorly) bio‐reducing. Disulfidhaltige IgG‐, Fc‐ oder Albumin‐basierte Prodrugs, die den FcRn‐Transportweg durch Endothelzellen nutzen, um länger im Körper zu verbleiben, könnten einer vorzeitigen biologischen Reduktion bei der FcRn‐Rezyklierung unterliegen. Eine entsprechende Analyse für redoxempfindliche Albuminkonjugate in zwei FcRn‐exprimierenden Zelllinien liefert neue Einblicke, um die Leistungsfähigkeit solcher Arzneistoffe zu steigern.
