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

Epimerisation in Peptide Synthesis
Molecules, 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
Frontiers 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,

An amalgamation of solid phase peptide synthesis and ribosomal peptide synthesis [PDF]
Peptide Science, 2008 AbstractExpressed protein ligation (EPL) is a protein semisynthesis technique that allows the site‐specific introduction of unnatural amino acids and biophysical probes into proteins. In the present study, we illustrate the utility of the approach through the generation of two semisynthetic proteins bearing spectroscopic probes. Dihydrofolate reductase

Synthesis of Chlorotoxin by Native Chemical Ligation
Journal of the Turkish Chemical Society, Section A: Chemistry, 2018 Chlorotoxin (CLTX) is a neurotoxin found in the venom of the Israeli scorpion, Leirius quinquestriatus. It contains 36-amino acids with four disulfide bonds and inhibits low-conductance chloride channels.

Solid-Phase Synthesis of Oxetane Modified Peptides [PDF]
Organic 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.

Chemistry of Peptide-Oligonucleotide Conjugates: A Review
Molecules, 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 ...

Exploration of the one-bead one-compound methodology for the design of prolyl oligopeptidase substrates. [PDF]
PLoS ONE, 2009 Here we describe the design, synthesis and evaluation of the first solid-phase substrates for prolyl oligopeptidase (POP), a cytosolic serine peptidase associated with schizophrenia, bipolar affective disorder and related neuropsychiatric disorders. This

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