Abstract
CPN-116 is a peptidic agonist that activates human neuromedin U receptor type 2 (NMUR2) but suffers from chemical instability due to inherent backbone isomerization on the Dap residue. To address this, a Leu-Dap-type (Z)-chloroalkene dipeptide isostere was synthesized diastereoselectively as a surrogate of the Leu-Dap peptide bond to develop a (Z)-chloroalkene analogue of CPN-116. The synthesized CPN-116 analogue is stable in 1.0 M phosphate buffer (pH 7.4) without backbone isomerization and can activate NMUR2 with similar potency to CPN-116 at nM concentrations (EC50 = 1.0 nM).

Abstract
Described here is the synthetic, spectroscopic, crystallographic, and computational analysis of a series of peptidomimetics containing l-Xaa-d-Yaa-type (Z)-chloroalkene dipeptide isosteres (CADIs) that were measured in an investigation of the β-turn mimicry of this peptide bond surrogate. We found that the 1,3-allylic strain across the chloroalkene moiety engenders the hyperconjugative interactions between the chloroalkene moiety and the C-H bonding or antibonding orbitals of the C-H bonds in allylic positions. These effects contribute significantly to the stabilization of β-turn structures.

Abstract
![]()
The solid-phase synthesis
of Gly-Ψ[CH(CF3)NH]-peptides
is presented. In order to achieve this goal, the synthesis of Gly-Ψ[CH(CF3)NH]-dipeptides having the C-terminus unprotected, the N-terminus
protected as Fmoc- or Teoc-, and possibly side chain functionalities
protected with acid-labile protecting groups has been developed. A
selected small library of six peptidomimetics, encompassing analogues
of biological relevant peptides, have been obtained in high purity.
