A new category of phosphonium based cationic amphiphilic peptides has been developed and evaluated as potential antimicrobial peptides and cell penetrating peptides. The required building blocks were conveniently accessible from cysteine and could be

Disulfide bonds play an important role in both proteins and peptides. They cause conformational constraints and increase the stability of such molecules. In nature, disulfide bonds are very common in animal and plant peptide toxins. These disulfide-r

A novel immobilized N-chlorosuccinimide resin was developed for peptide disulfide bond formation in combinatorial libraries. The resin is prepared in a simple two-step process from commercial starting materials. Disulfide formation is initiated by ad

We describe the synthesis of a range of novel dithiol-functionalized building blocks and demonstrate how they can be used to generate new structurally diverse dynamic combinatorial libraries. A proof-of-principle experiment using the catecholamine do

A series of monomers based on the methyl, ethyl, and isopropyl esters of Nα-(methacryloyl)-serine and -threonine were synthesized, and used in an AIBN-initiated radical polymerization reaction to yield polymers with an Mn ranging between 6.6 and 23.

Contrary to other studies, here we describe cysteine (Cys) pseudoproline-containing peptides with short deprotection times in TFA. The deprotection times fell in the same range as other protecting groups commonly used in SPPS (e.g., 1–3 h). Moreove

N-Chlorosuccinimide is described as a widely applicable on-resin disulfide-forming reagent. Disulfide bond formation was completed within 15 min in DMF. This strategy was successfully used in the synthesis of oxytocin and a regioselective synthesis o

Trimethoxyphenylthio (S-Tmp) is described as a novel cysteine protecting group in Fmoc solid phase peptide synthesis replacing the difficult to remove tert-butylthio. S-Tmp and dimethoxyphenylthio (S-Dmp) were successfully used for cysteine protectio

A novel method has been developed for the efficient formation of peptide disulfide bonds under aqueous conditions using N-chlorosuccinimide. Complete disulfide bond formation is achieved in 15 min with solvent mixtures containing water and acetonitri
