tetrapeptide-based beta-turn mimeticscontaining spirocyclic glucose-templated 3-hydroxyproline hybrids Glc3'(S)-5'(R)(CH(2)OH)HypH and Glc3'(S)-5'(S)(CH(2)OH)HypH as prolinemimetics is presented. NMR-based conformational analysis of Ac-Leu-D-Phe-[Glc3'(S)-5'(R)(CH(2)OH)HypH]-Val-NMe(2) and Ac-Leu-D-Phe-[Glc3'(S)-5'(S)(CH(2)OH)HypH]-Val-NMe(2) demonstrates the presence of beta-turn conformations. Different turn
