The synthesis of three new analogues of the cyclic cationic antimicrobial peptide Gramicidin S is described. These derivatives contain a modified turn region in which the DPhe-Pro motif has been replaced by a constrained furanoid sugar aminoacid or a flexible linear aminoethoxy acetic acidmoiety. Structural analysis revealed conformational changes in the modified turn region compared to GS. The biological
