β-Peptides with improved affinity for hDM2 and hDMX
摘要:
We previously described a series of 3(14)-helical beta-peptides that bind the hDM2 protein and inhibit its interaction with a p53-derived peptide in vitro. Here we present a detailed characterization of the interaction of these peptides with hDM2 and report two new beta-peptides in which non-natural side chains have been substituted into the hDM2-recognition epitope. These peptides feature both improved affinity and inhibitory potency in fluorescence polarization and ELISA assays. Additionally, one of the new beta-peptides also binds the hDM2- related protein, hDMX, which has been identified as another key therapeutic target for activation of the p53 pathway in tumors.

cyclic peptides based on the recent crystalstructure of MC4R in complex with the well-characterized antagonist SHU-9119 (Ac-Nle4-c[Asp5-His6-DNal(2′)7-Arg8-Trp9-Lys10]-NH2). These analogues were pharmacologically characterized in vitro, giving key insights into exploiting binding site subpockets to deliver more selective ligands. More specifically, the sidechains of the Nle4, DNal(2′)7, and Trp9 residues
protein complex using p53 α-helixmimetics has been shown to be a successful strategy to control p53 activity. To gain further insight into the binding of inhibitors to MDM2, the flexibility of four cyclic β-hairpins that act as α-helical mimetics and potential MDM2/p53 interaction inhibitors was investigated in relation to their inhibitory activity. MDM2-binding of the mimetics was determined using fluorescence

Methods and compositions are provided for generating macrocyclic peptides constrained by side-chain-to-C-terminus non-peptidic tethers for use as functional and structural mimics of α-helical motifs, including in therapeutic applications. These methods can be used to produce libraries of conformationally constrained peptidomimetics to identify compounds with desired activity properties.
