(Pseudo)amide-linked oligosaccharide mimetics: molecular recognition and supramolecular properties

Area of Science:

• Carbohydrate Chemistry
• Medicinal Chemistry
• Supramolecular Chemistry

Background:

• Oligosaccharides are vital for cell activities but are metabolically unstable.
• Developing stable carbohydrate mimetics is crucial for therapeutic applications.
• Current research focuses on mimetics that mimic natural oligosaccharide functions.

Purpose of the Study:

• To review advances in synthesizing oligosaccharide mimetics with amide and pseudoamide linkages.
• To explore the supramolecular and recognition properties of these mimetics.
• To highlight their therapeutic potential in various diseases.

Main Methods:

• Synthesis of carbohydrate mimetics replacing glycosidic linkages with amide/pseudoamide functions (thiourea, urea, guanidine).
• Investigation of molecular recognition and self-assembly properties.
• Evaluation of potential therapeutic applications.

Main Results:

• Efficient synthetic routes to amide and pseudoamide-linked oligosaccharide mimetics have been developed.
• These mimetics demonstrate competitive binding in cell adhesion and enzyme inhibition.
• Studies show promising supramolecular and recognition characteristics.

Conclusions:

• Oligosaccharide mimetics with amide/pseudoamide linkages offer metabolic stability and therapeutic potential.
• These compounds can interfere with carbohydrate-mediated biological processes.
• Further research into their synthesis and applications is warranted for drug development.
