    摘要: 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.

    摘要: The present invention provides inventive polypeptides comprising a C terminal RAB binding domain (RabBD) of RAB family interacting proteins (FIPs) stabilized by peptide stapling, and pharmaceutical compositions thereof. Also provided are methods for modulating RAB function comprising contacting an inventive stapled polypeptide with a RAB protein, and methods of treatment associated with modulation of RAB activity. The present invention also provides methods of making the inventive stapled polypeptides by ring closing metathesis of unstapled polypeptide precursors.
