5-Amino-3-methyl-Isoxazole-4-carboxylic Acid as a Novel Unnatural Amino Acid in the Solid Phase Synthesis of α/β-Mixed Peptides

open access: yesMolecules, 2022
The hybrid peptides consisting of α and β-amino acids show great promise as peptidomimetics that can be used as therapeutic agents. Therefore, the development of new unnatural amino acids and the methods of their incorporation into the peptide chain is ...

Solid-Phase Synthesis of Oxetane Modified Peptides [PDF]

open access: yesOrganic Letters, 2017
Solid-phase peptide synthesis (SPPS) is used to create peptidomimetics in which one of the backbone amide C═O bonds is replaced by a four-membered oxetane ring. The oxetane containing dipeptide building blocks are made in three steps in solution, then integrated into peptide chains by conventional Fmoc SPPS.

Epimerisation in Peptide Synthesis

open access: yesMolecules, 2023
Epimerisation is basically a chemical conversion that includes the transformation of an epimer into another epimer or its chiral partner. Epimerisation of amino acid is a side reaction that sometimes happens during peptide synthesis.

Realizing Serine/Threonine Ligation: Scope and Limitations and Mechanistic Implication Thereof

open access: yesFrontiers in Chemistry, 2014
Serine/Threonine ligation (STL) has emerged as an alternative tool for protein chemical synthesis, bioconjugations as well as macrocyclization of peptides of various sizes. Owning to the high abundance of Ser/Thr residues in natural peptides and proteins,

Synthesis of cyclotetrapeptide analogues of c-PLAI and evaluation of their antimicrobial properties [PDF]

open access: yesRoyal Society Open Science, 2021
Antimicrobial peptides (AMPs) are interesting compounds owing to their ability to kill several pathogens. In order to identify new AMPs, c-PLAI analogues were synthesized and evaluated together with their linear precursors for their antimicrobial ...

Chemistry of Peptide-Oligonucleotide Conjugates: A Review

open access: yesMolecules, 2021
Peptide-oligonucleotide conjugates (POCs) represent one of the increasingly successful albeit costly approaches to increasing the cellular uptake, tissue delivery, bioavailability, and, thus, overall efficiency of therapeutic nucleic acids, such as ...
