topical-peptides-and-proteins-for-aging-skin The intricate world of peptide chemistry often necessitates the total chemical synthesis of complex molecules to unlock their therapeutic potential or to facilitate fundamental research. Among these complex structures, cinnamycin, a 19-amino acid lantibiotic, presents a fascinating target for synthetic chemists.2023年6月5日—SPPS is a method used to create peptidesby assembling amino acids in a stepwise fashion on a solid support, such as a resin. Its unique structure, characterized by a lan (lanthionine) and two MeLan (methyllanthionine) residues, along with an unusual lysinoalanine (Lal) bridge, makes its synthesis a considerable challenge. Fortunately, advancements in solid-phase peptide synthesis (SPPS) have revolutionized the ability to construct such peptides, enabling precise control over the sequence and facilitating the incorporation of non-canonical amino acids.

Solid-phase peptide synthesis, pioneered by Bruce Merrifield in 1963, has become a cornerstone technique for preparing peptides and small chemical molecules. This methodology involves the stepwise assembly of amino acids onto an insoluble solid support, typically a resin. This approach offers significant advantages over traditional solution-phase methods, which often require laborious purification steps after each coupling. In SPPS, excess reagents can be easily washed away, simplifying the process and allowing for the efficient construction of longer peptide chains. The solid-phase synthesis of cinnamycin and its analogues has been explored extensively. For instance, the peptide of CinA (CinA1–19) has been successfully synthesized using solid-phase peptide synthesis.

The total solid phase approach for cinnamycin involves a meticulously planned series of reactions. The process begins with the selection of an appropriate resin and the attachment of the first amino acid, which will form the C-terminus of the peptide.作者：B Mothia·2012·被引用次数：2—Thesynthesisof two sets of different orthogonally protected lanthionine ready for incorporation intosolid phase peptide synthesisto form cyclised peptides ... Subsequent amino acids are then coupled sequentially, with each step involving deprotection of the N-terminus of the growing peptide chain and activation of the incoming amino acid for amide bond formation.Unparalleled Solid Phase Peptide Peptide Synthesis Various coupling reagents, such as DCC (dicyclohexylcarbodiimide), are commonly employed to facilitate peptide bond formation. The success of SPPS hinges on the efficiency of each coupling and deprotection step, as even minor inefficiencies can lead to truncated or modified sequences, impacting the overall yield and purity of the final product.作者：JM Collins·2014·被引用次数：265—ABSTRACT: A series of improvements to the standardsolid phase peptide synthesis(SPPS) process allowing for significant.
