ABSTRACT
Hepcidin, a 25 amino acid peptide hormone containing a complex network of four disulfide bonds is the hormone regulator of iron homeostasis. Three bridges synthetic peptide analogs have been prepared following two synthetic strategies and two oxidation procedures i) a microwave-assisted solid phase synthesis followed by air oxidation of the six free cysteines ii) a manual solid phase synthesis followed by stepwise deprotection and oxidation of cysteine pairs. All the peptides with different connectivities have been characterized by MALDI ToF spectrometry, and tested for their ability to degrade the cellular iron exporter, ferroportin. While linear peptides are inactive, the one-bridge and two-bridge peptides retaining protected cysteines by bulky substituents are active. Similarly, the three-bridge peptides are active irrespective of their disulfide connectivities.
