标 题:Solution-phase affinity selection of inhibitors from combinatorial peptide libraries
发明人：PENTELUTE BRADLEY L; TOUTI FAYCAL

摘要:The present invention provides novel peptides (e.g., peptides, macrocyclic peptides, mini-proteins) that modulate protein-protein interactions or salts thereof, and methods of making and using the inventive peptides. In some embodiments, the peptides are high affinity inhibitors (e.g., K D of at most 100 nM, at most 10 nM, at most 1 nM) of a protein-protein interaction. In certain embodiments, these peptides interfere with p53-MDM2 binding interactions (e.g., by binding to MDM2 (GenBank® Gene ID: 4193)). In some embodiments, the peptides interfere with the dimerization of the C-terminal domain of the human immunodeficiency virus (HIV) capsid protein (C-CA), comprising residues 146-231 of the HIV capsid protein (e.g., by binding to the C-terminal domain of the HIV capsid protein (C-CA), thereby inhibiting the dimeric interface of HIV capsid protein, thereby inhibiting viral assembly). These inventive peptides were rapidly generated and identified using novel methods described herein comprising combinatorial peptide synthesis and/or solution affinity selection.
