- Foldamers
A foldamer is a discrete chain
molecule oroligomer that adopts asecondary structure stabilized by non-covalent interactions Ref|1 Ref|2. They are artificial molecules that mimic the ability ofprotein s,nucleic acid s, andpolysaccharide s to fold into well-defined conformations, such ashelices and β-sheets. Foldamers have been demonstrated to display a number of interesting supramolecular properties includingmolecular self-assembly ,molecular recognition , andhost-guest chemistry . They are studied as models of biological molecules and have been shown to displayantimicrobial activity. They also have great potential application to the development of new functional materials.Examples:
* "m"-Phenylene ethynylene oligomers are driven to fold into a helical conformation bysolvophobic force s and aromatic stacking interactions.
* β-peptides are composed ofamino acid s containing an additionalmethylene unit between theamine andcarboxylic acid . They are more stable to enzymatic degradation and have been demonstrated to have antimicrobial activity.
*Aedamer s that fold in aqueous solutions driven by hydrophobic and aromatic stacking interactions.References
