Template-fixed β-hairpin peptidomimetics of the general formula 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 which, as the remaining symbols in the above formula, are defined in the description and the claims, and salts thereof, have the property to selectively inhibit the growth of or to kill microorganisms such as Pseudomonas aeruginosa. 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.

Dye conjugates of template-fixed β-hairpin peptidomimetics of the general formula (I) wherein Z is a template-fixed chain of 14 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 which, as the remaining symbols in the above formula, are defined in the description and the claims, and salts thereof, have CXCR4 antagonizing properties, and are useful for cancer therapy; diagnostic imaging; for detection of tumors and other abnormalities; for photoacoustic tumor imaging, detection and therapy; and for sonofluorescence tumor imaging, detection and therapy. The various dyes forming part of these conjugates are useful over the range of 300-1200 nm, the exact range being dependent upon the particular dye. These dye conjugates of β-hairpin peptidomimetic can be manufactured by processes which are based on a mixed solid- and solution phase synthetic strategy.

The template-fixed β-hairpin peptidomimetics Cyclo(-Tyr-His-X-Cys-Ser-Ala-DPro-Dab-Arg-Tyr-Cys-Tyr-Gln-Lys-DPro-Pro), disulfide bond between Cys4 and Gys11, and pharmaceutically acceptable salts thereof, with X being Ala or Tyr, have CXCR4 antagonizing properties and can be used for preventing HIV infections in healthy individuals or for slowing and halting viral progression in infected patients; or where Cancer is mediated or resulting from CXCR4 receptor activity; or where immunological diseases are mediated or resulting from CXCR4 receptor activity; or for treating immuno suppression; or, in particular, for stem cell mobilization of peripheral blood stem cells and/or mesenchymal stem cell (MSC) and/or other stem cells which retention depend on the CXCR4-receptor. These β-hairpin peptidomimetics can be manufactured by a process which is based on a mixed solid- and Solution phase synthetic strategy, using methods which are well known to those adequately skilled in peptide chemistry.

摘要:
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 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.
