Understanding Stapled Peptides

At their core, peptides are short chains of amino acids that play crucial roles in biological processes.Enhancing Specific Disruption of Intracellular Protein ... However, inherent limitations such as poor stability, low cell permeability, and rapid degradation by proteases have historically hindered their therapeutic utility. Stapling is a sophisticated chemical modification technique that addresses these limitations by introducing a covalent bond, or "staple," between amino acid residues within the peptide chain. This ingenious modification typically involves introducing non-natural amino acids, such as alkenyl amino acids, which are then cross-linked, often through a hydrocarbon bridge, to form a full-carbon scaffold.

This structural reinforcement confers several crucial benefits. The stapled peptide structure stabilizes the crucial α-helical structure, a common and functional conformation in many biologically active peptides. This enhanced structural integrity leads to a significant improvement in pharmacologic performance. Specifically, stapling can greatly improve the target affinity of peptides, meaning they bind more strongly and specifically to their intended molecular partners. Furthermore, this stabilization dramatically increases proteolytic resistance, safeguarding the peptide from degradation by enzymes in the body, thereby increasing its serum half-life.Advancing Peptide Synthesis Through Stapled Peptides

Advantages for Intracellular Drug Targets

The ability of stapled peptides to overcome the inherent challenges of targeting molecules within the cell is a key reason for their growing prominence. Unlike small molecules, which can struggle with specificity and off-target effects, and larger biologics, which often have difficulty crossing the cell membrane, stapled peptides offer a compelling middle ground.Stapled Peptides Inhibitors: A New Window for Target Drug ...

One of the most significant advantages is their enhanced cell-penetrating ability. The stabilized α-helical structure and modifications introduced during the stapling process can facilitate entry into cellsStapled peptides: targeting protein-protein interactions in .... In some cases, stapled peptides themselves can act as potent cell-penetrating agents, or they can be used as carriers to transport various cargos to intracellular targets作者：D Thean·2017·被引用次数：34—A library ofstapled peptideswas synthesized and screened to identify compounds that bound Mdm2 and activated cellular p53.. This property is critical for addressing disease mechanisms that reside within the cell.

Moreover, stapled peptides excel at modulating protein-protein interactions (PPIs), which are fundamental to countless cellular processes and are frequently disrupted in disease. Many intracellular PPIs have been considered "undruggable" by conventional means due to their large, flat interaction surfaces. However, stapled peptides, with their ability to mimic natural protein interfaces and an increased capacity to bind to these broad surfaces, show a remarkable ability to inhibit intracellular PPIs that previously have been intractable with traditional small molecule or biologics. This opens up new avenues for therapeutic intervention in diseases driven by aberrant PPIs.作者：M Moiola·2019·被引用次数：207—Stapled peptidesconsist of peptide chains that bring an external brace that force the peptide structure into an α -helical one.
