Abstract:
Polyproline II helix (PPII) is one of the secondary structures in proteins that play an important role in various biological processes. In this study, we have developed a new macrocyclization strategy that efficiently reinforces a model tetrapeptide into a PPII structure. We also elucidated some relationships between structural features and PPII stability in this model. This new macrocyclic stapling strategy can serve as a useful chemical tool to manipulate the PPII structure for various applications.

Stability of Substituted Cyclohexanes
The two chair conformations of cyclohexanes undergo rapid interconversion at room temperature. Both forms have identical energies and stabilities, each comprising equal amounts of the equilibrium mixture. Replacing a hydrogen atom with a functional group makes the two conformations energetically non-equivalent.
For example, in...
Conformations of Cyclohexane
The chair form is the most stable and derives its name from its resemblance to the “easy chair.” In the chair conformation, two carbon atoms are arranged out-of-plane — one above and one below, minimizing the torsional strain. In the chair form, the bond angle is very close to the ideal...
