Abstract
Native chemical ligation (NCL) has been playing an increasingly important role in chemical protein synthesis (CPS). More efficient ligation methods that circumvent the requirement of a peptidyl thioester and thiol additive-which allow the following desulfurization or refolding in one pot-are urgently needed for the synthesis of more complex protein targets and in large quantities. Herein, we discover that the weak acyl donor peptidyl N-acyl pyrazole can be activated by azole reagents like 3-methylpyrazole or imidazole to facilitate its ligation directly with an N-terminal cysteine peptide. As it requires no thioester or thiol additive, this ligation strategy can be conveniently combined with metal-free desulfurization (MFD) or oxidative protein folding to allow various one-pot protocols. The utility and generality of the strategy are showcased by the total synthesis of ubiquitin via an N-to-C sequential ligation-MFD strategy, the semi-synthesis of the copper protein azurin, and the efficient assembly of a sulfated hirudin variant and the cyclotide kalata B1, all in a one-pot fashion.

Abstract
Native chemical ligation is a key reaction in the toolbox of chemical methods for the synthesis of native and modified proteins. The catalysis of ligation is commonly performed by using small aryl-thiol molecules added at high concentrations. In this work, we incorporated thiotyrosine, a non-canonical amino acid containing an aryl-thiol moiety, into a designed cyclic protein « sans queue ni tête ». Importantly, the protein environment reduced the pKa of the thiol group to 5.8-5.9, which is significantly lower than the previously reported value for thiotyrosine in a short peptide (pKa 6.4). Furthermore, we demonstrated the catalytic activity of this protein both as hydrolase and in native chemical ligation of peptides. These results will be useful for the development of efficient protein catalysts (enzymes) for protein synthesis and modification.

Abstract
Thioesters are considered to be "energy-rich" functional groups that are susceptible to attack by thiolate and amine nucleophiles while remaining hydrolytically stable at neutral pH, which enables thioester chemistry to take place in an aqueous medium. Thus, the inherent reactivity of thioesters enables their fundamental roles in biology and unique applications in chemical synthesis. Here, we investigate the reactivity of thioesters that mimic acyl-coenzyme A (CoA) species and S-acylcysteine modifications as well as aryl thioesters applied in chemical protein synthesis by native chemical ligation (NCL). We developed a fluorogenic assay format for the direct and continuous investigation of the rate of reaction between thioesters and nucleophiles (hydroxide, thiolate, and amines) under various conditions and were able to recapitulate previously reported reactivity of thioesters. Further, chromatography-based analyses of acetyl- and succinyl-CoA mimics revealed striking differences in their ability to acylate lysine side chains, providing insight into nonenzymatic protein acylation. Finally, we investigated key aspects of native chemical ligation reaction conditions. Our data revealed a profound effect of the tris-(2-carboxyethyl)phosphine (TCEP) commonly used in systems where thiol-thioester exchange occurs, including a potentially harmful hydrolysis side reaction. These data provide insight into the potential optimization of native chemical ligation chemistry.

Abstract
The native chemical ligation reaction of peptide thioesters with cysteinyl peptides is a pivotal chemical process in the production of native or modified peptides and proteins, and well beyond in the preparation of various biomolecule analogs and materials. To benefit from this reaction at its fullest and to access all the possible applications, the experimentalist needs to know the factors affecting its rate and how to control it. This concept article presents the fundamental principles underlying the rate of the native chemical ligation and its homogeneous catalysis by nucleophiles. It has been prepared to serve as a quick guide in the search for an appropriate catalyst.

Abstract
Biology utilizes multiple strategies, including sequestration in lipid vesicles, to raise the rate and specificity of chemical reactions through increases in effective molarity of reactants. We show that micelle-assisted reaction can facilitate native chemical ligations (NCLs) between a peptide-thioester – in which the thioester leaving group contains a lipid-like alkyl chain – and a Cys-peptide modified by a lipid-like moiety. Hydrophobic lipid modification of each peptide segment promotes the formation of mixed micelles, bringing the reacting peptides into close proximity and increasing the reaction rate. The approach enables the rapid synthesis of polypeptides using low concentrations of reactants without the need for thiol catalysts. After NCL, the lipid moiety is removed to yield an unmodified ligation product. This micelle-based methodology facilitates the generation of natural peptides, like Magainin 2, and the derivatization of the protein Ubiquitin. Formation of mixed micelles from lipid-modified reactants shows promise for accelerating chemical reactions in a traceless manner. Sequestration of reactants in lipid vesicles is a strategy prevalent in biological systems to raise the rate and specificity of chemical reactions. Here, the authors show that micelle-assisted reactions facilitate native chemical ligation between a peptide-thioester and a Cys-peptide modified by a lipid-like moiety.

Abstract
Cyclic peptide-based therapeutics have a promising growth forecast that justifies the development of microfluidic systems dedicated to their production, in phase with the actual transitioning toward continuous flow and microfluidic technologies for pharmaceutical production. The application of the most popular method for peptide cyclization in water, i.e., native chemical ligation, under microfluidic conditions is still unexplored. Herein, we report a general strategy for fast and efficient peptide cyclization using native chemical ligation under homogeneous microfluidic conditions. The strategy relies on a multistep sequence that concatenates the formation of highly reactive S-(2-((2-sulfanylethyl)amino)ethyl) peptidyl thioesters from stable peptide amide precursors with an intramolecular ligation step. With very fast ligation rates (<5 min), even for the most difficult junctions (including threonine, valine, isoleucine, or proline), this technology opens the door toward the scale-independent, expedient preparation of bioactive macrocyclic peptides. Flow-based peptide synthesis is a well-established method, yet difficult to combine with native chemical ligation (NCL), the go-to method for peptide cyclization. Here, the authors developed a microfluidic procedure for peptide cyclization within minutes, using NCL and an SEA alkylthioester peptide.

Abstract
The present review offers an overview of nonclassical (e.g., with no pre- or in situ activation of a carboxylic acid partner) approaches for the construction of amide bonds. The review aims to comprehensively discuss relevant work, which was mainly done in the field in the last 20 years. Organization of the data follows a subdivision according to substrate classes: catalytic direct formation of amides from carboxylic and amines ( section 2 ); the use of carboxylic acid surrogates ( section 3 ); and the use of amine surrogates ( section 4 ). The ligation strategies (NCL, Staudinger, KAHA, KATs, etc.) that could involve both carboxylic acid and amine surrogates are treated separately in section 5 .
