Beyond Simple Mimicry: Next-Generation Geometric Architectures and Future Paradigms in Small-Molecule and Macrocyclic...

Area of Science:

• Medicinal Chemistry
• Structural Biology
• Drug Discovery

Background:

• Peptidomimetics have advanced from simple inhibitors to sophisticated drug scaffolds.
• There is a critical need to overcome the limitations of peptide therapeutics.
• The field is shifting towards converting peptide motifs into orally available small molecules.

Purpose of the Study:

• To highlight geometric design principles for next-generation peptidomimetic architectures.
• To showcase strategies for targeting protein-protein interactions (PPIs).
• To discuss the future of peptidomimetics in drug discovery.

Main Methods:

• Geometric design principles: linear repetition, convergent fusion, and cyclization.
• Development of repeating-unit oligomers, heterocycle-centered scaffolds, and macrocyclic frameworks.
• Integration of automated synthesis and AI-driven design.

Main Results:

• Novel architectures enable targeting of complex protein-protein interactions (PPIs).
• Repeating-unit oligomers, heterocycle scaffolds, and macrocycles offer diverse structural strategies.
• Advanced architectures incorporate dynamic responsiveness and multi-structure platforms.

Conclusions:

• Geometric logic transforms peptidomimetics into a primary therapeutic modality.
• This approach enables engagement of the human interactome, including "undruggable" PPIs.
• The convergence of design, synthesis, and AI will revolutionize therapeutic development.
