Template-fixed β-hairpin mime tics of the general formula R1-Cys-Z-Cys-R2 (1) wherein the two Cys residues are bridged by a disulfide bond thereby forming a cyclic peptide; R1 and R2 are preferably Glu-Thr and Thr-Lys; or Lys-Thr and Thr-Glu; or Thr-Glu and Lys-Thr, or Thr-Lys and Glu-Thr; or Leu-Glu and Lys-Val; or Val-Lys and Glu-Leu; or Glu-Leu and Val-Lys; or Lys-Leu and Val-Glu; or Asn-Gly and Lys-Val; or Val-Gly and Lys-Asn; or Gly-Asn and Val-Lys; or Gly-Val and Asn-Lys; or Gly-Gly and Gly-Gly; or Glu-Leu-Lys and Glu-Val-Lys; or Lys-Val-Glu and Lys-Leu-Glu; or Leu-Glu-Lys and Glu-Lys-Val; or Val-Lys-Glu and Lys-Glu-Leu; or Glu-Lys-Leu and Val-Glu-Lys; or Lys-Glu-Val and Leu-Lys-Glu; or Lys-Glu-Leu and Val-Lys-Glu; or Glu-Lys-Val and Leu-Glu-Lys; or Lys-Val-Gly and Gly-Leu-Glu; or Glu-Leu-Gly and Gly-Val-Lys; or Val-Lys-Gly and Gly-Glu-Leu; or Leu-Glu-Gly and Gly-Lys-Val; or Val-Gly-Lys and Glu-Gly-Leu; or Leu-Gly-Glu and Lys-Gly-Val; or Gly-Gly-Gly and Gly-Gly-Gly; and Z is a chain of n amino acid residues with n being an integer form 4 to 20 and with each of these n amino acid residues being, independently, derived from any naturally occurring L-α-amino acid are provided. Libraries comprising a plurality of these templates can be used for the construction of phage display derived template-fixed β-hairpin mimetics generating phage display libraries with very high binding constants to targets, thus combining the advantage of screening of large phage display derived template-fixed β-hairpin libraries which in turn considerably facilitates structure-activity studies, and hence the discovery of new molecules with potent activities and with novel selectivities towards different types of targets.

Template-fixed β-hairpin mimetics and libraries including a plurality of these mimetics are provided. The template-fixed β-hairpin mimetics are of the following general formula: R1-Cys-Z-Cys-R2 I wherein the two cysteine residues are bridged by a disulfide bond, thereby forming a cyclic peptide; R1 and R2 are di- or tripeptide moieties of certain types, as defined herein; and Z is a chain of n amino acid residues with n being an integer from 4 to 20 and with each of these n amino acid residues being, independently, derived from any naturally occurring L-α-amino acid.

Template-fixed β-hairpin peptidomimetics of the general formula (I), wherein Z is a template-fixed chain of 12 α-amino acid residues which, depending on their positions in the chain (counted starting from the N-terminal amino acid) are Gly or Pro, or of certain types, at least one of these residues being of the type of N-substituted glycines, which types, as the remaining symbols in the above formula, are defined in the description and the claims, and salts thereof, have the property to inhibit the growth of or to kill microorganisms. They can be used as disinfectants for foodstuffs, cosmetics, medicaments or other nutrient-containing materials or as medicaments to treat or prevent infections. These β-hairpin peptidomimetics can be manufactured by processes which are based on a mixed solid- and solution phase synthetic strategy.
