Front Cover: Corrin Ring Modification in Peptide Drug Development – a Brief History of “Corrination” (ChemMedChem 10/2025)

The cover art shows the coronation of peptides crowning new routes to peptide administration, targeted delivery and novel structures. These new peptides show potential for oral delivery, improved protease stability, prevention of aggregation and changes to central nervous system versus peripheral nervous system localization. More details can be found in article 10.1002/cmdc.202500129 by Nancy Cham and Robert P. Doyle.
