Enzyme-catalyzed radical-mediated C-H functionalization reactions allow nature to create natural products of unusual three-dimensional structures from simple linear peptide precursors. In comparison, chemist’s ability to harness radical C-H functionalization reactions for synthesis of complex peptides remains limited. In this work, new methods have been developed to construct peptide macrocycles via radical-mediated intramol. C-H alkylation reactions under photoredox catalysis. Linear peptide precursors equipped with a C-terminal N-(acyloxy)phthalimide ester can cyclize with the α C-H bond of N-terminal glycine or aryl C-H bond of N-heteroarene capping units in high yield and selectivity under mild conditions. The strategy uses the C-H cyclization step to incorporate lysine, homolysine, and various heteroarene-derived amino acid linchpins into peptide macrocycles, enabling convergent and flexible synthesis of complex peptide macrocycles from simple building blocks. The results came from multiple reactions, including the reaction of H-Lys(Boc)-OH(cas: 2418-95-3Quality Control of H-Lys(Boc)-OH)

We describe herein a reaction for the chemo- and site-selective replacement of carbamates with various other carbamates only at the N-terminus of peptides.

And the article was published in Biomaterials Science in 2019. Formula: C11H22N2O4 The author mentioned the following in the article:

Proteins are fragile such that even freezing, drying and dehydration may induce their denaturation, aggregation, and activity loss. To protect proteins from these kinds of damage, we prepared two types of amino acid polymers, PLG-r-PLL and PLG, from the efficient ring-opening polymerization of α-amino acid N-carboxyanhydride using LiHMDS as the initiator. β-Galactosidase was used in this study to examine the protein protecting effect of the synthesized amino acid polymers during lyophilization. The results indicate that both PLG-r-PLL and PLG exert significant protection on β-Gal during lyophilization and improve the activity of the resulting protein from 40%, without using a protecting agent during lyophilization, to 80% of the original protein activity. Nevertheless, PLG generally performs better than PLG-r-PLL independent of the chain length. Our studies also show that PLG and PLG-r-PLL with a high content of PLG subunits display no observable cytotoxicity and hemolytic effect. Furthermore, DLS and TEM characterization indicate that PLG protects β-Gal upon lyophilization by preventing the aggregation of β-Gal. Our studies demonstrate that amino acid polymers, such as PLG, can exert potent activity for protein stabilization. The easy operation of LiHMDS-initiated and efficient NCA polymerization implies the great potential of this strategy to prepare amino acid polymers quickly for the screening of protein stabilization and mechanism study.

The article was titled 《Submonomeric strategy with minimal protection for the synthesis of C(2)-modified peptide nucleic acids》, and you may find the article in Organic Letters.Application In Synthesis of H-Lys(Boc)-OH The information in the text is summarized as follows:

A novel synthesis of C(2)-modified peptide nucleic acids (PNAs) is proposed, using a submonomeric strategy with minimally protected building blocks, which allowed a reduction in the required synthetic steps. N(3)-unprotected, D-Lys- and D-Arg-based backbones were used to obtain pos. charged PNAs with high optical purity, as inferred from chiral GC measurements. “”Chiral-box”” PNAs targeting the G12D point mutation of the KRAS gene were produced using this method, showing improved sequence selectivity for the mutated- vs wild-type DNA strand with respect to unmodified PNAs.

The author of the article were Yang, Fangping; Liu, Zhiwei; Si, Wenting; Song, Ziyuan; Yin, Lichen; Tang, Haoyu. The article conveys some information:

Polysaccharide-polypeptide conjugates have gained a broad interest in mimicking the structure and bioactivity of peptidoglycans or proteoglycans for biomedical applications. Efficient and precise preparation of the conjugates is challenging and unresolved, mainly because of the mismatched solubility between polysaccharide initiators and N-carboxyanhydrides (NCAs), which frequently results in competing side reactions and oligomeric polypeptide chain. Herein, we report a facile and efficient strategy to prepare the conjugates with well-controlled polypeptide chain length (lp) directly from unmodified polysaccharides via a biphasic solution ring-opening polymerization The effect of lp on surface antibacterial properties has been investigated. Elongating the lp can significantly potentiate the antibiofilm property of the conjugate coatings. Our results may provide opportunities to develop various polypeptide-based conjugates with well-defined structures toward versatile uses.

Recommanded Product: H-Lys(Boc)-OHOn May 31, 2019, Gless, Bengt H.; Bojer, Martin S.; Peng, Pai; Baldry, Mara; Ingmer, Hanne; Olsen, Christian A. published an article in Nature Chemistry. The article was 《Identification of autoinducing thiodepsipeptides from staphylococci enabled by native chemical ligation》. The article mentions the following:

Staphylococci secrete autoinducing peptides (AIPs) as signaling mols. to regulate population-wide behavior. AIPs from non-Staphylococcusaureus staphylococci have received attention as potential antivirulence agents to inhibit quorum sensing and virulence gene expression in the human pathogen Staphylococcus aureus. However, only a limited number of AIP structures from non-S. aureus staphylococci have been identified to date, as the minute amounts secreted in complex media render it difficult. Here, we report a method for the identification of AIPs by exploiting their thiolactone functionality for chemoselective trapping and enrichment of the compounds from the bacterial supernatant. Standard liquid chromatog. mass spectrometry anal., guided by genome sequencing data, then readily provides the AIP identities. Using this approach, we confirm the identity of five known AIPs and identify the AIPs of eleven non-S. aureus species, and we expect that the method should be extendable to AIP-expressing Gram-pos. bacteria beyond the Staphylococcus genus.
