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,

Development of a hypersensitive periodate-cleavable amino acid that is methionine- and disulfide-compatible and its application in MHC exchange reagents for T cell Characterisation [PDF]

open access: yes, 2012
Incorporation of cleavable linkers into peptides and proteins is of particular value in the study of biological processes. Here we describe the synthesis of a cleavable linker that is hypersensitive to oxidative cleavage as the result of the periodate ...

Aqueous Microwave-Assisted Solid-Phase Synthesis Using Boc-Amino Acid Nanoparticles

open access: yesApplied Sciences, 2013
We have previously developed water-based microwave (MW)-assisted peptide synthesis using Fmoc-amino acid nanopaticles. It is an organic solvent-free, environmentally friendly method for peptide synthesis.

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 ...

Solid-Phase Synthesis of the Lipopeptide Myr-HBVpreS/2-78, a Hepatitis B Virus Entry Inhibitor

open access: yesMolecules, 2010
Chronic HBV infection is the leading cause of liver cirrhosis and hepatocellular carcinoma (HCC). Synthetic peptides derived from the N-terminus of the large HBV envelope protein (L-protein) have been shown to efficiently block HBV entry.

Liquid-Phase Peptide Synthesis (LPPS): A Third Wave for the Preparation of Peptides.

open access: yesChemical Reviews, 2022
Since the last century, peptides have gained wide acceptance as drugs, with almost 100 already in the market and a large number in the pipeline. In this context, peptide synthesis has grown massively as a stringent field for pharmaceuticals around the ...

Prevention of aspartimide formation during peptide synthesis using cyanosulfurylides as carboxylic acid-protecting groups

open access: yesNature Communications, 2020
Aspartimide formation is a frequently occurring problem during peptide synthesis. Here, the authors present cyanosulfurylides as a protection group that masks aspartic acid residues during solid phase peptide synthesis, thus preventing aspartimide ...

DNA display III. Solid-phase organic synthesis on unprotected DNA. [PDF]

open access: yesPLoS Biology, 2004
DNA-directed synthesis represents a powerful new tool for molecular discovery. Its ultimate utility, however, hinges upon the diversity of chemical reactions that can be executed in the presence of unprotected DNA.

A facile, inexpensive scalable route to α-methyl cysteine [PDF]

open access: yes, 2013
A facile, scalable synthesis of α-methyl cysteine with three alternate thiol protecting groups (Trt, Allyl and tBu) is described. The thiol protected amino acids are obtained in 6 steps from L-cysteine ethyl ester and are ideally suited for a range of ...
