Peptides: Design, Synthesis, and Biological Activity
Design, synthesis and biological evaluation of immunostimulating mannosylated desmuramyl peptides
The simplest and minimal modification of a single amino acid or peptide bonds is represented by N-methylation. This can improve the pharmacokinetic properties of biologically active peptides as well as resulting in analogues that show specific biological activity such as enzyme inhibitors, receptor antagonists and agonists, building blocks in combinatorial chemistry for the screening of new potential drugs.
Further, structural and conformational studies performed with N-methylated analogues of natural amino acids and peptides enabled to i produce stable foldamers with different topology with respect to the helix of natural and endogenous peptides, ii confer to modified peptides high stability against proteases and iii enhance lipophilicity and bioavailability for pharmacological purposes.

Consequentially, it is crucial to provide optically pure N-methyl-amino acids and N-methylated peptides with a large supply. The present report will focus on the results obtained in the last decade in the field of chemical synthetic methodologies for the N-methylation of amino acids. Keywords: N-methyl amino acids, N-methyl peptides, N-methylation, peptidomimetics.
Abstract: The simplest and minimal modification of a single amino acid or peptide bonds is represented by N-methylation. The therapeutic and bioengineering landscape of peptides reflects a wide spectrum of biomedical potentials by expanding into new chemistry strategies, molecular diversity and medical indications.
Personalized neoantigen vaccination strategies have attracted significant research and clinical attentions as a new class of cancer immunotherapy. All data from this study demonstrate the feasibility of a novel, rapid and highthroughput strategy to identify T-cell Receptors targeting specific tumor antigens.
The rapid advancement of synthesis technology continues to further expand the boundaries of creative and unique peptide design, synthesis and applications. Here, peptides were applied to increase the number of extracellular vesicles EVs released from the peptide-treated cells, which presents intrinsic therapeutic potentials of EVs as ideal candidates in developing pharmaceuticals.
