    • The invention describes a method for selecting a polypeptide ligand having a desired level of specificity for a target, wherein the polypeptide ligand comprises a polypeptide comprising at least three reactive groups, separated by at least two loop sequences, and a molecular scaffold which formscovalent bonds with the reactive groups of the polypeptide such that at least two polypeptide loops are formed on the molecular scaffold, comprising (i) screening at least two different sets of polypeptide ligands against the target, and selecting one or more ligands from each library which interact with the target; (ii) comparing the activity of the selected ligands with one or more paralogues or orthologues of the target; and (iii) further selecting one or more ligands according to their activity towardssaid one or more paralogues or orthologues; wherein said two or more different sets of ligands differ in the length of the polypeptide loops formed on the molecular scaffold.
    • 本发明描述了一种用于选择对靶标具有期望的特异性水平的多肽配体的方法,其中多肽配体包含多肽,该多肽配体包含至少三个由至少两个环序列分开的反应性基团的多肽,以及分子支架,其与 所述多肽的反应性基团使得在分子支架上形成至少两个多肽环,其包含(i)筛选针对靶的至少两种不同组的多肽配体,以及从每个文库中选择一个或多个与 目标; (ii)将所选配体的活性与目标的一个或多个旁系同源物或直向同源物进行比较; 和(iii)根据它们的活性进一步选择一种或多种配体,所述配体依赖于一个或多个旁系同源物或直向同源物; 其中所述两种或更多种不同的配体组在分子支架上形成的多肽环的长度不同。
