Vicinal Disulfide Constrained Cyclic Peptidomimetics: a Turn Mimetic Scaffold Targeting the Norepinephrine Transporter

21 June 2016

Loopy peptides: Peptide turn mimetics of a clinically relevant norepinephrine reuptake inhibitor were developed employing a high-throughput synthesis approach to generate peptide thioesters, with subsequent cyclization through native chemical ligation. The vicinal disulfide constrained cyclic peptidomimetics (see scheme) show high structural and functional similarity to the parent peptide, though with superior metabolic stability.
