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.

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 ...

HOBt·DCHA-Mediated Synthesis of Sterically Hindered Peptides employing Fmoc-Amino Acid Chlorides in Both Solution-Phase and Solid Phase Methods [PDF]

open access: yes, 2008
The synthesis of peptides employing Fmoc-amino acid chlorides in presence of HOBt·DCHA salt in solution as well as by the solid-phase methods is described. The coupling was found to be complete in 30 min and free from racemization.

N-Butylpyrrolidinone (NBP) for Solid-Phase Peptide Synthesis, Environmentally Friendlier and Synthetically Better than DMF.

open access: yesChemSusChem, 2020
Solid-phase peptide synthesis (SPPS) is the method of choice for the preparation of peptides in both, laboratory scale and large production. Although the methodology has been improved during the last decades allowing the achievement of long peptides and ...

Exploration of the one-bead one-compound methodology for the design of prolyl oligopeptidase substrates. [PDF]

open access: yesPLoS 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

The Synthesis of cis- and trans-Fused Bicyclic Sugar Amino Acids [PDF]

open access: yes, 2006
Four isomeric bicyclic sugar amino acids (SAAs) were prepared from an α-acetylenic-C-glucoside by employing a Petasis olefination and a ring-closing metathesis (RCM) as key steps.
