Antibacterial peptidomimetics based on guanidine-functionalized di-tertiary amides.

ABSTRACT: Tertiary amides such as peptoids are a novel class of peptidomimetics that offer enhanced structure, activity, and stability compared to many naturally occurring antimicrobial peptides. Guanidino compounds have gained interest in medicinal chemistry as cell-penetrating molecules. This work investigates the changes in the antibacterial activity of modified guanidino groups on the structure of active guanidino tertiary amides by incorporating lipophilic, hydrophobic, and extra cationic groups, thereby combining the properties of the tertiary amide in the peptoid backbone with the important role of addition of extra cationic and lipophilic residues, such as those in AMPs, but supported by guanidine backbones.
