Oligo-benzamide-based peptide mimicking tools for modulating biology.

Area of Science:

• Medicinal Chemistry
• Organic Synthesis
• Biochemistry

Background:

• Protein-protein interactions (PPIs) are crucial in biological processes but also implicated in diseases.
• Alpha-helices are common structural motifs in proteins that mediate many PPIs.
• Mimicking these natural structures with synthetic molecules offers a therapeutic strategy.

Purpose of the Study:

• To design and synthesize oligo-benzamide scaffolds that mimic protein alpha-helices.
• To evaluate the ability of these compounds to disrupt protein-protein interactions.
• To explore their potential as therapeutic agents.

Main Methods:

• Design of rigid oligo-benzamide frameworks capable of presenting functional groups in an alpha-helix-like conformation.
• Development of efficient, iterative synthetic routes for oligo-benzamide production in solution and on solid phase.
• In vitro and in vivo studies to assess protein binding and disruption of PPIs.

Main Results:

• Oligo-benzamides demonstrated outstanding alpha-helix mimicry.
• Compounds showed strong binding to target proteins.
• Effective disruption of protein-protein interactions was observed both in vitro and in vivo.

Conclusions:

• Oligo-benzamides represent a promising class of synthetic molecules for alpha-helix mimetics.
• Their efficient synthesis and potent inhibition of PPIs highlight their therapeutic potential.
• Further development could lead to novel treatments for diseases driven by aberrant protein interactions.
