Abstract
Peptides are remarkably interesting alternatives to several applications. In particular, antimicrobial sequences have raised major interest of the scientific community due to the resistance acquired by commonly used antibiotics. Amongst these, some dimeric peptides have shown very promising characteristics as strong biological activities and resistance against degradation by peptidases. However, despite such promising characteristics, a relatively small number of studies address dimeric peptides, mainly due to the synthesis-related obstacles in their production, whereas the well-implemented routines of solid phase peptide synthesis-which includes the possibility of automation-makes life significantly easier. Here, we present kinetic investigations of the dimerization of a cysteine-containing sequence to obtain the homodimeric antimicrobial peptide homotarsinin. Based on the structural and membrane interaction data already available for the dimer and its monomeric chain, we have proposed distinct dimerization protocols in selected environments, namely, aqueous buffer, TFE:H2O and micellar solutions. The experimental results were adjusted by a theoretical model. Both the kinetic profiles and the reaction yields are dependent on the reaction medium, clearly indicating that aggregation, peptide structure, and peptide-membrane interactions play major roles in the formation of the disulfide bond. Finally, the rationalization of the different aspects addressed here is expected to contribute to research and applications that demand the obtainment of dimeric peptides.

Abstract
The currently synthetic methods of peptide heterodimer involve tedious synthesis and purification steps. An acid-labile traceless linker was prepared, which is highly compatible with the Fmoc strategy and could be used to prepare peptide heterodimer on resin. The linker could be cleaved concomitantly with peptide cleavage, and two model heterodimers were synthesized. The proposed synthesis procedure is simple, straightforward, and provides great convenience for preparing disulfide-linked peptide heterodimers.

Abstract
Among the available protocols, chemically driven approaches to oxidize cysteine may not be required for molecules that, under the native-like conditions, naturally fold in conformations ensuring an effective pairing of the right disulfide bridge pattern. In this contest, we successfully prepared the distinctin, a natural heterodimeric peptide, and some synthetic cyclic peptides that are inhibitors of the CXCR4 receptor. In the first case, the air oxidation reaction allowed to connect two peptide chains via disulfide bridge, while in the second case allowed the cyclization of rationally designed peptides by an intramolecular disulfide bridge. Computational approaches helped to either drive de-novo design or suggest structural modifications and optimal oxidization protocols for disulfide-containing molecules. They are able to both predict and to rationalize the propensity of molecules to spontaneously fold in suitable conformations to achieve the right disulfide bridges.

Abstract
The solution phase synthesis of N-protected amino acids and peptides has been achieved through the Group-Assisted Purification (GAP) chemistry by avoiding disadvantages of other methods in regard to the difficult scale-up, expenses of solid and soluble polymers, etc. The GAP synthesis can reduce the use of solvents, silica gels, energy and manpower. In addition, the GAP auxiliary can be conveniently recovered for re-use and is environmentally friendly and benign, and substantially reduces waste production in academic labs and industry.
