Miniature β-Hairpin Mimetic by Intramolecular Hydrogen Bond and C-H···π Interactions. [PDF]

ACS Omega, 2022
Canonically, protein β-hairpin motifs are stabilized by intramolecular hydrogen bonds. Here, we attempt to develop a rational design recipe for a miniature hairpin structure stabilized by hydrogen bonding as well as C–H···π interaction and try to ...
