Definition
Peptide-like oligomer in which the side chains are attached to the backbone nitrogen atoms instead of the α-carbons (N-substituted glycines).

Detailed Explanation

Peptide-like oligomer in which the side chains are attached to the backbone nitrogen atoms instead of the α-carbons (N-substituted glycines). This subtle shift makes peptoids completely resistant to proteases — no enzyme has evolved to cleave N-substituted amide bonds — while maintaining the ability to fold into defined structures and bind biological targets. Peptoids are synthesized efficiently on solid phase using the 'submonomer' method, which uses cheap primary amines instead of expensive Fmoc-amino acids.

Peptoid libraries can be rapidly diversified since hundreds of commercially available amines can serve as side chains. Antimicrobial peptoids mimicking the amphipathic structure of AMPs show potent antibacterial activity. Peptoid-peptide hybrids combine the stability of peptoids with the target specificity of peptides.
