Aromatic Interactions in Glycochemistry: From Molecular Recognition to Catalysis

Area of Science:

• Biochemistry
• Molecular Biology
• Chemical Biology

Background:

• Aromatic platforms are key recognition elements in proteins like carbohydrate-binding domains (CBDs), RNA receptors, and enzymes.
• These platforms stabilize complexes via CH/π interactions with pyranose units, influencing binding affinity and receptor function.
• Recent research highlights the role of aromatic units in stabilizing glycoside cationic transition states.

Purpose of the Study:

• To dissect the forces stabilizing carbohydrate/aromatic complexes.
• To delineate the relationship between chemical structures and interaction strength.
• To explore the influence of these interactions on glycoside reactivity.

Main Methods:

• Extensive studies over the last decade.
• Dissection of stabilizing forces.
• Analysis of structure-interaction relationships.

Main Results:

• Identified key forces stabilizing carbohydrate/aromatic complexes.
• Established correlations between chemical structures and interaction strength.
• Demonstrated the influence of aromatic interactions on glycoside reactivity.

Conclusions:

• Aromatic platforms are crucial for stabilizing biological complexes involving carbohydrates.
• The chemical structure of glycosides and aromatic groups dictates interaction strength.
• These interactions significantly impact the reactivity of glycosides.
