Parallel solid-phase synthesis of diaryltriazoles

Area of Science:

• Medicinal Chemistry
• Organic Synthesis
• Chemical Biology

Background:

• Protein-protein interactions (PPIs) are crucial in cellular processes.
• Disrupting PPIs is a key strategy for drug discovery.
• Existing peptide mimics have limitations in stability and delivery.

Purpose of the Study:

• To develop a novel class of small molecule inhibitors for PPIs.
• To synthesize substituted diaryltriazoles using an efficient solid-phase protocol.
• To evaluate the potential of these compounds as peptide mimics.

Main Methods:

• Solid-phase synthesis utilizing a modified Wang resin.
• Copper(I)- or Ruthenium(II)-catalyzed 1,3-dipolar cycloaddition reactions.
• Parallel synthesis enabling rapid generation of compound libraries.

Main Results:

• Successful preparation of a series of substituted diaryltriazoles.
• High yields achieved in many cases using the developed protocol.
• Demonstrated structural similarity to terphenyl-alpha-helix peptide mimics.

Conclusions:

• The developed solid-phase synthesis is efficient for diaryltriazole preparation.
• Substituted diaryltriazoles are promising scaffolds for targeting PPIs.
• These compounds offer potential as stable, non-peptide alternatives to peptide mimics.
