    • The present invention provides novel stabilized crosslinked compounds having secondary structure motifs, libraries of these novel compounds, and methods for the synthesis of these compounds libraries thereof. The synthesis of these novel stabilized compounds involves (1) synthesizing a peptide from a selected number of natural or non-natural amino acids, wherein said peptide comprises at least two moieties capable of undergoing reaction to promote carbon-carbon bond formation; and (2) contacting said peptide with a reagent to generate at least one crosslinker and to effect stabilization of a secondary structure motif. The present invention, in a preferred embodiment, provides stabilized p53 donor helical peptides. Additionally, the present invention provides methods for disrupting the p53/MDM2 binding interaction comprising (1) providing a crosslinked stabilized α-helical structure; and (2) contacting said crosslinked stabilized α-helical structure with MDM2.
    • 本发明提供具有二级结构基序的新型稳定化交联化合物,这些新化合物的文库,以及合成这些化合物文库的方法。 这些新型稳定化合物的合成涉及(1)从选定数量的天然或非天然氨基酸合成肽,其中所述肽包含至少两个能够进行促进碳 - 碳键形成反应的部分; 和(2)使所述肽与试剂接触以产生至少一种交联剂并实现二级结构基序的稳定化。 本发明在优选的实施方案中提供稳定的p53供体螺旋肽。 另外,本发明提供了破坏p53 / MDM2结合相互作用的方法,其包括(1)提供交联的稳定的α-螺旋结构; 和(2)使所述交联的稳定的α-螺旋结构与MDM2接触。
