Publication Abstract from PubMed

Strategic incorporation of achiral C(alpha,alpha)-dialkylated amino acids with bulky substituents into peptides can be used to promote extended strand conformations and inhibit protein-protein interactions associated with amyloid formation. In this work, we evaluate the thermodynamic impact of chiral C(alpha,alpha) monomers on folding preferences in such systems through introduction of a series of C(alpha)-methylated and C(alpha)-ethylated residues into a beta-hairpin host sequence. Depending on stereochemical configuration of the artificial monomer and potential for additional hydrophobic packing, a C(alpha)-ethyl-C(alpha)-propyl glycine residue can provide similar or enhanced folded stability relative to an achiral C(alpha,alpha)-diethyl analogue.
