Summary
Researchers developed N-alkoxy peptoids using alkoxyamines for controlled solid-phase synthesis. These peptoid oligomers exhibit a stable, single conformation, suggesting potential for polyproline II structures in peptidomimetic drug design.
Area of Science:
- Biochemistry
- Organic Chemistry
- Polymer Science
Background:
- Peptoid oligomers are valuable peptidomimetics due to their synthesis ease, chemical diversity, and molecular recognition capabilities.
- Controlling peptoid structure, especially backbone amide conformation, is crucial for developing advanced functional peptoids.
Purpose of the Study:
- To introduce alkoxyamines as a novel reagent for solid-phase peptoid synthesis.
- To synthesize and characterize N-alkoxy peptoid oligomers.
- To investigate the conformational properties of these novel peptoids.
Main Methods:
- Solid-phase synthesis utilizing alkoxyamine reagents.
- Nuclear Magnetic Resonance (NMR) spectroscopy for structural analysis.
- Computational modeling to predict secondary structure propensity.
Main Results:
- Successful synthesis of N-alkoxy peptoid oligomers was achieved.
- NMR data revealed that the synthesized oligomers adopt a single, stable conformation.
- The stable conformation is characterized by the presence of trans amide bonds.
Conclusions:
- N-alkoxy peptoids demonstrate a strong propensity to adopt a polyproline II type secondary structure.
- The use of alkoxyamines offers enhanced control over peptoid backbone conformation.
- These findings pave the way for designing novel peptidomimetics with predictable structures and functions.

01:05Proteoglycans
Glycans, a class of complex heterogeneous molecules, can be covalently attached to proteins to form glycosylated proteins that regulate various physiological and pathological processes. Glycosylated proteins or glycoproteins comprise N-linked and O-linked oligosaccharides. O-glycosylation is the most common type of protein glycosylation. Here, glycans attach to the oxygen atom of the hydroxyl groups of Serine or Threonine residues. O-linked glycosylation occurs later in protein processing,...
01:24Oligosaccharide Assembly
Protein glycosylation starts in the ER lumen and continues in the Golgi apparatus. Glycosyltransferases catalyze the addition of sugar molecules or glycosylation of proteins. Usually, these enzymes add sugars to the hydroxyl groups of selected serine or threonine residues to form O-linked glycans or the amino groups of asparagine residues to form N-linked glycans. Different positions on the same polypeptide chain can contain differently linked glycans.

01:25Protein Glycosylation
Glycosylation, the most common post-translational modification for proteins, serves diverse functions. Adding sugars to proteins makes the proteins more resistant to proteolytic digestion. Glycosylated proteins can act as markers and receptors to promote cell-cell adhesion. Additionally, they have many essential quality control functions in the cell, such as correct protein folding and facilitating transport of misfolded proteins to the cytosol, which can be degraded.

02:43Peptide Bonds
A peptide bond covalently attaches amino acids through a dehydration reaction. One amino acid's carboxyl group and another amino acid's amino group combine, releasing a water molecule. The resulting bond is the peptide bond. The products that such linkages form are peptides. As more amino acids join this growing chain, the resulting chain is a polypeptide. Each polypeptide has a free amino group at one end. This end has the N-terminal, or the amino-terminal, and the other end has a free...
01:29Protein Folding Quality Check in the RER
ER is the primary site for the maturation and folding of soluble and transmembrane secretory proteins. The calnexin cycle is a specific chaperone system that folds and assesses the confirmation of N-glycosylated proteins before they can exit the ER lumen. The primary players of this quality check pipeline are the lectins, ER-resident chaperones, and a glucosyl transferase enzyme. In case the calnexin system in the lumen fails to salvage a misfolded protein, it is transported to the cytoplasm...
01:24Protein Organization
Proteins are polymers of amino acid residues. They are versatile and responsible for different cellular functions, including DNA replication, molecular transport, catalysis, and structural support. Proteins have a hierarchical structure comprising at least three levels of organization: primary, secondary, and tertiary structure. Some large proteins have a quaternary structure where individual protein subunits are linked together.
The primary structure of a protein is its amino acid sequence.
