[d-Pro5,5′]-Gramicidin S was synthesized to confirm a prediction that d-d sequence at the corner position had low preference for β-turn. The analog showed much weaker activity than gramicidin S and also showed different CD spectra from those of gramicidin S. The results indicate that the analog can not take stable, gramicidin S-like, β-sheet conformation.
