    • Template-fixed β-hairpin mimetics of the general formula R 1 -Cys-Z-Cys-R 2 (I) wherein the two Cys residues are bridged by a disulfide bond thereby forming a cyclic peptide; R l and R 2 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.
    • 通式R 1 -Cys-Z-Cys-R 2(I)的模板固定的β-发夹模拟物,其中两个Cys残基被二硫键桥接,从而形成环肽; R 1和R 2优选为Glu-Thr和Thr-Lys; 或Lys-Thr和Thr-Glu; 或Thr-Glu和Lys-Thr; 或Thr-Lys和Glu-Thr; 或Leu-Glu和Lys-Val; 或Val-Lys和Glu-Leu; 或Glu-Leu和Val-Lys; 或Lys-Leu和Val-Glu; 或Asn-Gly和Lys-Val; 或Val-Gly和Lys-Asn; 或Gly-Asn和Val-Lys; 或Gly-Val和Asn-Lys; 或Gly-Gly和Gly-Gly; 或Glu-Leu-Lys和Glu-Val-Lys; 或Lys-Val-Glu和Lys-Leu-Glu; 或Leu-Glu-Lys和Glu-Lys-Val; 或Val-Lys-Glu和Lys-Glu-Leu; 或Glu-Lys-Leu和Val-Glu-Lys; 或Lys-Glu-Val和Leu-Lys-Glu; 或Lys-Glu-Leu和Val-Lys-Glu; 或Glu-Lys-Val和Leu-Glu-Lys; 或Lys-Val-Gly和Gly-Leu-Glu; 或Glu-Leu-Gly和Gly-Val-Lys; 或Val-Lys-Gly和Gly-Glu-Leu; 或Leu-Glu-Gly和Gly-Lys-Val; 或Val-Gly-Lys和Glu-Gly-Leu; 或Leu-Gly-Glu和Lys-Gly-Val; 或Gly-Gly-Gly和Gly-Gly-Gly; 并且Z是n个氨基酸残基的链,其中n是4至20的整数,并且这些n个氨基酸残基中的每一个独立地衍生自任何天然存在的L-α-氨基酸。 包含多个这些模板的文库可用于构建噬菌体展示衍生的模板固定的β-发夹模拟物,其产生具有非常高的结合常数的靶标的噬菌体展示文库,因此结合筛选大噬菌体展示衍生模板固定的优点 β-发夹文库反过来极大地促进结构活性研究,从而发现具有有效活性和对不同类型靶标具有新选择性的新分子。
