Abstract
Interleukin-6 (IL-6), a multifunctional cytokine, is an attractive therapeutic target for immunological and inflammatory diseases. We investigated the chemical synthesis of IL-6 and its enantiomer (d-IL-6) using a sequential N-to-C native chemical ligation strategy from six peptide segments. Solubilizing Trt-K10 tags improved the intermediate solubility and served as protecting groups during the metal-free desulfurization to facilitate the synthesis of full-length IL-6 protein. Synthetic l-IL-6 and recombinant IL-6 exhibited nearly identical structural and binding properties. The symmetrical binding property of d-IL-6 was also demonstrated by functional analysis using IL-6-binding peptides. The resulting functional d-IL-6 was employed to screen a phage-displayed antibody fragment library, leading to the identification of several d-IL-6-binding single-domain antibodies. This work will contribute to the development of novel, potent IL-6 inhibitors without the adverse effects of undesired immune activation.

Abstract
Methods enabling the dechalcogenation of thiols or selenols have been investigated and developed for a long time in fields of research as diverse as the study of prebiotic chemistry, the engineering of fuel processing techniques, the study of biomolecule structures and function or the chemical synthesis of biomolecules. The dechalcogenation of thiol or selenol amino acids is nowadays a particularly flourishing area of research for being a pillar of modern chemical protein synthesis, when used in combination with thiol or selenol-based chemoselective peptide ligation chemistries. This review offers a comprehensive and scholarly overview of the field, emphasizing emerging trends and providing a detailed and critical mechanistic discussion of the dechalcogenation methods developed so far. Taking advantage of recently published reports, it also clarifies some unexpected desulfurization reactions that were observed in the past and for which no explanation was provided at the time. Additionally, the review includes a discussion on principal desulfurization methods within the framework of newly introduced green chemistry metrics and toolkits, providing a well-rounded exploration of the subject.

Abstract
Mirror-image proteins (D-proteins) are useful in biomedical research for purposes such as mirror-image screening for D-peptide drug discovery, but the chemical synthesis of many D-proteins is often low yielding due to the poor solubility or aggregation of their constituent peptide segments. Here, we report a Lys-C protease-cleavable solubilizing tag and its use to synthesize difficult-to-obtain D-proteins. Our tag is easily installed onto multiple amino acids such as DLys, DSer, DThr, and/or the N-terminal amino acid of hydrophobic D-peptides, is impervious to various reaction conditions, such as peptide synthesis, ligation, desulfurization, and transition metal-mediated deprotection, and yet can be completely removed by Lys-C protease under denaturing conditions to give the desired D-protein. The efficacy and practicality of the new method were exemplified in the synthesis of two challenging D-proteins: D-enantiomers of programmed cell death protein 1 IgV domain and SARS-CoV-2 envelope protein, in high yield. This work demonstrates that the enzymatic cleavage of solubilizing tags under denaturing conditions is feasible, thus paving the way for the production of more D-proteins.

Abstract
Chronic infection with hepatitis B virus (HBV) is a major cause of cirrhosis and liver cancer. Capsid assembly modulators can induce error-prone assembly of HBV core proteins to prevent the formation of infectious virions, representing promising candidates for treating chronic HBV infections. To explore novel capsid assembly modulators from unexplored mirror-image libraries of natural products, we have investigated the synthetic process of the HBV core protein for preparing the mirror-image target protein. In this report, the chemical synthesis of full-length HBV core protein (Cp183) containing an arginine-rich nucleic acid-binding domain at the C-terminus is presented. Sequential ligations using four peptide segments enabled the synthesis of Cp183 via convergent and C-to-N direction approaches. After refolding under appropriate conditions, followed by the addition of nucleic acid, the synthetic Cp183 assembled into capsid-like particles.

Abstract
We developed a new cysteine-specific solubilizing tag strategy via a cysteine-conjugated succinimide. This solubilizing tag remains stable under common native chemical ligation conditions and can be efficiently removed with palladium-based catalysts. Utilizing this approach, we synthesized two proteins containing notably difficult peptide segments: interleukin-2 (IL-2) and insulin. This IL-2 chemical synthesis represents the simplest and most efficient approach to date, which is enabled by the cysteine-specific solubilizing tag to synthesize and ligate long peptide segments. Additionally, we synthesized a T8P insulin variant, previously identified in an infant with neonatal diabetes. We show that T8P insulin exhibits reduced bioactivity (a 30-fold decrease compared to standard insulin), potentially contributing to the onset of diabetes in these patients. In summary, our work provides an efficient tool to synthesize challenging proteins and opens new avenues for exploring research directions in understanding their biological functions.

Abstract
The T cell immunoreceptor with immunoglobulin and immunoreceptor tyrosine-based inhibitory motif domain (TIGIT) is an inhibitory immunoreceptor expressed on lymphocytes that serves as a promising target for cancer immunotherapy. In this study, facile synthetic protocols to produce the extracellular domain of TIGIT were investigated for applications of TIGIT in mirror-image screening. During the synthesis via sequential native chemical ligations, we encountered problems with significantly poor solubility of the ligated products. Introducing trityl-type solubilizing auxiliaries, which also functioned as temporary protecting groups for cysteine residues, facilitated a flexible order of ligations and efficient purification protocols. After refolding under appropriate conditions, the synthetic TIGIT showed a sufficient affinity toward its target ligand CD155.

Abstract
Proteins with highly hydrophobic regions or aggregation-prone sequences are typically difficult targets for chemical synthesis at the current stage, as obtaining such type of peptides via solid-phase peptide synthesis requires sophisticated operations. Herein, we report N,O-benzylidene acetal dipeptides (NBDs) as robust and effective building blocks to allow the direct synthesis of difficult peptides and proteins via a kinked backbone strategy. The effectiveness and easy accessibility of NBDs have been well demonstrated in our chemical syntheses of various challenging peptides and proteins, including chemokine, therapeutic hormones, histone, and glycosylated erythropoietin.

Abstract
Chemical synthesis of hydrophobic proteins presents a formidable task as they are often difficultly achieved via peptide synthesis, purification, and peptide ligation. Thus, peptide solubilizing strategies are needed to integrate with peptide ligation to achieve protein total synthesis. Herein, we report a tunable backbone modification strategy, taking advantage of the tunable stability of the Cys/Pen ligation intermediate, which allows for readily introducing a solubilizing tag for both peptide purification and ligation processes. The effectiveness of this strategy was demonstrated by the chemical synthesis of interleukin-2.

Abstract
Proteins modified in a controlled manner with artificial moieties such as fluorophores or affinity tags have been shown to be a powerful tool for functional or structural analysis of proteins. A reliable way to prepare proteins with a well-defined modification is protein synthesis. Although many successful syntheses have been reported, the poor aqueous solubility of synthetic intermediates causes difficulty in the chemical synthesis of proteins. Here we describe a solubilizing strategy for poorly soluble peptides which uses chemoselective incorporation of a hydrophilic tag onto a hydrazide in a peptide. We found that a hydrophilic tag possessing a dialkoxybenzaldehyde moiety can react with peptide hydrazides through reductive N-alkylation. No protecting groups are required for this reaction, and peptides modified in this way show enhanced solubility and consequently good peak separation during HPLC purification. The tag can be removed subsequently by treatment with trifluoroacetic acid to generate a free hydrazide, which can be converted in a one-pot reaction to a thioester for further modification. This method was validated by synthesis of a Lys63-linked ubiquitin dimer derivative. This late-stage solubilization can be applied in principal to any peptide and opens the possibility of the synthesis of proteins that have previously been considered inaccessible due to their poor solubility.

Abstract
Chemical synthesis of proteins with aggregable or colloidal peptide segments presents a formidable task, as such peptides prove to be difficult for both solid-phase peptide synthesis and peptide ligation. To address this issue, we have developed ligation embedding aggregation disruptor (LEAD) as an effective strategy for the chemical synthesis of difficult-to-obtain proteins. The N,O/S-benzylidene acetals generated from Ser/Thr ligation and Cys/Pen ligation are found to effectively disrupt peptide aggregation, and they can be carried for sequential ligations toward protein synthesis. The effectiveness and generality of this strategy have been demonstrated with total syntheses of programmed cell death protein 1 immunoglobulin like V-type domain and extracellular domain.

Abstract
Native chemical ligation (NCL) provides a powerful solution to assemble proteins with precise chemical features, which enables a detailed investigation of the protein structure-function relationship. As an extension to NCL, the discovery of desulfurization and expressed protein ligation (EPL) techniques has greatly expanded the efficient access to large or challenging protein sequences via chemical ligations. Despite its superior reliability, the NCL-desulfurization protocol requires orthogonal protection strategies to allow selective desulfurization in the presence of native Cys, which is crucial to its synthetic application. In contrast to traditional thiol protecting groups, photolabile protecting groups (PPGs), which are removed upon irradiation, simplify protein assembly and therefore provide minimal perturbation to the peptide scaffold. However, current PPG strategies are mainly limited to nitro-benzyl derivatives, which are incompatible with NCL-desulfurization. Herein, we present for the first time that quinoline-based PPG for cysteine can facilitate various ligation strategies, including iterative NCL and EPL-desulfurization methods. 7-(Piperazin-1-yl)-2-(methyl)quinolinyl (PPZQ) caging of multiple cysteine residues within the protein sequence can be readily introduced via late-stage modification, while the traceless removal of PPZQ is highly efficient via photolysis in an aqueous buffer. In addition, the PPZQ group is compatible with radical desulfurization. The efficiency of this strategy has been highlighted by the synthesis of γ-synuclein and phosphorylated cystatin-S via one-pot iterative ligation and EPL-desulfurization methods. Besides, successful sextuple protection and deprotection of the expressed Interleukin-34 fragment demonstrate the great potential of this strategy in protein caging/uncaging investigations.

Abstract
Disulfide-rich proteins are useful as drugs or tool molecules in biomedical studies, but their synthesis is complicated by the difficulties associated with their folding. Here, we describe a removable glycosylation modification (RGM) strategy that expedites the chemical synthesis of correctly folded proteins with multiple or even interchain disulfide bonds. Our strategy comprises the introduction of simple O-linked β-N-acetylglucosamine (O-GlcNAc) groups at the Ser/Thr sites that effectively improve the folding of disulfide-rich proteins by stabilization of their folding intermediates. After folding, the O-GlcNAc groups can be efficiently removed using O-GlcNAcase (OGA) to afford the correctly folded proteins. Using this strategy, we completed the synthesis of correctly folded hepcidin, an iron-regulating hormone bearing four pairs of disulfide-bonds, and the first total synthesis of correctly folded interleukin-5 (IL-5), a 26 kDa homodimer cytokine responsible for eosinophil growth and differentiation.

Abstract
Native chemical ligation (NCL) enables the total chemical synthesis of proteins. However, poor peptide segment solubility remains a frequently encountered challenge. Here we introduce a traceless linker that can be temporarily attached to Glu side chains to overcome this problem. This strategy employs a new tool, Fmoc-Glu(AlHx)-OH, which can be directly installed using standard Fmoc-based solid-phase peptide synthesis. The incorporated residue, Glu(AlHx), is stable to a wide range of chemical protein synthesis conditions and is removed through palladium-catalyzed transfer under aqueous conditions. General handling characteristics, such as efficient incorporation, stability and rapid removal were demonstrated through a model peptide modified with Glu(AlHx) and a Lys6 solubilizing tag. Glu(AlHx) was incorporated into a highly insoluble peptide segment during the total synthesis of the bacteriocin AS-48. This challenging peptide was successfully synthesized and folded, and it has comparable antimicrobial activity to the native AS-48. We anticipate widespread use of this easy-to-use, robust linker for the preparation of challenging synthetic peptides and proteins.

Abstract
Herein, we developed a bifunctional reagent rac-2-Br-DMNPA 2 for the late-stage protection of peptide cysteine. Through the identification of its t-Bu ester 1 as a more competent form under ligation conditions, facile N-terminal and side-chain caging for the model peptide and protein were accomplished. Building upon this, a one-pot ligation and photolysis strategy was applied in the synthesis of the mini-protein chlorotoxin. More importantly, we extended the utility of 2 as a bifunctional linker for traceless solid-phase chemical ligation.

Abstract
Caveolin-1, which is an essential protein for caveola formation, was chemically synthesized. It is composed of 177 amino acid residues, is triply palmitoylated at the C-terminal region, and is inserted into the lipid bilayer to form a V-shaped structure in the middle of the polypeptide chain. The entire sequence was divided into five peptide segments, each of which was synthesized by the solid-phase method. To improve the solubility of the C-terminal region, O-acyl isopeptide structures were incorporated. After ligation by the thioester method and the introduction of the palmitoyl groups, all the protecting groups were removed and the isopeptide structures were converted into the native peptide bond. Finally, the obtained polypeptide was successfully inserted into bicelles, thus showing the success of the synthesis.

Abstract
A novel late-stage solubilization of peptides using hydrazides is described. A solubilizing tag was attached through a selective N-alkylation at a hydrazide moiety with the aid of a 2-picoline-borane complex in 50% acetic acid-hexafluoro-2-propanol. The tag, which tolerates ligation and desulfurization conditions, can be detached by a Cu-mediated selective oxidative hydrolysis of the N-alkyl hydrazide. This new method was validated through the synthesis of HIV-1 protease.

Abstract
![]()
The chemical synthesis of a highly hydrophobic membrane-associated peptide by native
chemical ligation (NCL) in an ionic liquid (IL) [C2mim][OAc]/buffer mixture
was achieved by employing peptide concentrations up to 11 mM. NCL was studied at
different pH and water content and compared to several “gold-standard”
ligation protocols. The optimized reaction protocol for the NCL in IL required the
addition of 40% water and pH adjustment to 7.0–7.5, resulting in ligation yields
of up to 80–95% within 1 to 4 h. This new ligation protocol is generally
applicable and outperforms current “gold-standard” NCL methods.

Abstract
One of the main limitations encountered during the chemical synthesis of proteins through native chemical ligation (NCL) is the limited solubility of some of the peptide segments. The most commonly used solution to overcome this problem is to derivatize the segment with a temporary solubilizing tag. Conveniently, the tag can be introduced on the thioester segment in such a way that it is removed concomitantly with the NCL reaction. We herein describe a generalization of this approach to N-terminal cysteinyl segment counterparts, using a straightforward synthetic approach that can be easily automated from commercially available building blocks, and applied it to a well-known problematic target, SUMO-2.

Abstract
Chemists have been interested in the N-alkylation of a peptide bond because such a modification alters the conformation of the amide bond, interferes with hydrogen bond formation, and changes other properties of the peptide (e.g., solubility). This modification also opens the door for attaching functional groups for various applications. Nonetheless, the irreversibility of some of these modifications and the harsh conditions required for their removal currently limits the wide utility of this approach. Herein, we report applying a propargyl group for peptide bond modification at diverse junctions, which can be removed under mild and aqueous conditions via treatment with gold(I). Considering the straightforward conditions for both the installation and removal of this group, the propargyl group provides access to the benefits of backbone N-alkylation, while preserving the ability for on-demand depropargylation and full recovery of the native amide bond. This reversible modification was found to improve solid-phase peptide synthesis as demonstrated in the chemical synthesis of NEDD8 protein, without the use of special dipeptide analogues. Also, the reported approach was found to be useful in decaging a broad range of propargyl-based protecting groups used in chemical protein synthesis. Remarkably, reversing the order of the two residues in the propargylation site resulted in rapid amide bond cleavage, which extends the applicability of this approach beyond a removable backbone modification to a cleavable linker. The easy attach/detach of this functionality was also examined in loading and releasing of biotinylated peptides from streptavidin beads.

Abstract
Solid phase peptide synthesis (SPPS) provides the possibility to chemically synthesize peptides and proteins. Applying the method on hydrophilic structures is usually without major drawbacks but faces extreme complications when it comes to "difficult sequences." These includes the vitally important, ubiquitously present and structurally demanding membrane proteins and their functional parts, such as ion channels, G-protein receptors, and other pore-forming structures. Standard synthetic and ligation protocols are not enough for a successful synthesis of these challenging sequences. In this review we highlight, summarize and evaluate the possibilities for synthetic production of "difficult sequences" by SPPS, native chemical ligation (NCL) and follow-up protocols.

Abstract
Interferon-stimulated gene 15 (ISG15) is a member of the ubiquitin-like modifiers (ULM) family, which adopts a β-grasp fold domain(s) similar to ubiquitin (Ub) with only minor sequence homology. ISG15 consists of two Ub-like domains and aids the immune system in neutralizing infections by numerous pathogens and plays an important role in defending cells against many viruses including influenza A. Recently, Ub was found to be a substrate for ISG15, which can be ISGylated on Lys29 and Lys48, while the former is more dominant. The discovery of such hybrid ISG15-Ub chains brought forward various fundamental questions regarding the nature and effect of this conjugation. To further investigate the role of hybrid ISG15-Ub chains, the pure homogeneous material of these chains is needed in workable quantities. By applying advanced chemical strategies for protein synthesis, we report the total chemical synthesis of a 231-residue ISG15-Lys29-Ub hybrid chain. During the synthesis we encountered insoluble peptide fragments, and therefore we developed a new reversible Acm based solubilizing tag to efficiently tackle this hurdle. This new Acm tag was compared with the known Arg based Acm solubilizing tag and was found to be more reliable in terms of incorporation and efficiency as demonstrated in the synthesis of the native ISG15-Ub hybrid chain.

Abstract
Hydrophobic membrane peptides/proteins having low water solubility are often difficult to prepare. To overcome this issue, temporal introduction of solubilizing tags has been demonstrated to be beneficial. Following our recent work on the solubilization of a difficult target by using a hydrophilic oligo-Lys tag bearing a trityl linker (Trt-K method), this paper describes a comparative study of the solubilizing abilities of several peptidic trityl tags containing Lys, Arg, Glu, Asn, Nε-tri-Me-Lys or Cys-sulfonate using two hydrophobic model peptides. Among the tags evaluated, that containing Nε-tri-Me-Lys exhibits superior solubilizing ability.

Abstract
During the total chemical synthesis of the water-soluble globular Haemophilus Influenzae DNA ligase (Hin-Lig), we observed the surprising phenomenon of a soluble peptide segment that failed to undergo native chemical ligation. Based on dynamic light scattering and transmission electron microscopy experiments, we determined that the peptide formed soluble colloidal particles in a homogeneous solution containing 6 m guanidine hydrochloride. Conventional peptide performance-improving strategies, such as installation of a terminal/side-chain Arg tag or O-acyl isopeptide, failed to enable the reaction, presumably because of their inability to disrupt the formation of soluble colloidal particles. However, a removable backbone modification strategy recently developed for the synthesis of membrane proteins did disrupt the formation of the colloids, and the desired ligation of this soluble but unreactive system was eventually accomplished. This work demonstrates that an appropriate solution dispersion state, in addition to good peptide solubility, is a prerequisite for successful peptide ligation.

Abstract
Solubilizing trityl tags (Trt-oligoLys/Arg) proved applicable to metal-free radical-triggered desulfurization and an Ag-mediated thioester method. Additionally, using the solubilizing trityl tag strategy, synthesis of the influenza BM2 proton channel, which previously required organic solvent-aided native chemical ligation (NCL) and desulfurization due to its low solubility, was achieved without using organic solvents.

Abstract
Hydrophobic proteins, as one of the cellular protein classifications, play an essential function in maintaining the normal life cycle of living cells. Researches on the structure and function of hydrophobic proteins promote the exploration of the causes of major diseases, and development of new therapeutic agents for disease treatment. However, the poor water solubility of hydrophobic proteins creates problems for their preparation, separation, characterization and functional studies. The temporary solubilizing tags are considered a practical strategy to effectively solve the poor water solubility problem of hydrophobic proteins. This strategy can significantly improve the water solubility of hydrophobic peptides/proteins, making them like water-soluble peptides/proteins easy to be purified, characterized. More importantly, the temporary solubilizing tags can be removed after protein synthesis, so thus the structure and function of the hydrophobic proteins are not affected. At present, temporary solubilizing tags have been successfully used to prepare many important hydrophobic proteins such as membrane proteins, lipoproteins and chaperones. In this review, we summarize the recent researches and applications of temporary solubilizing tags.

Abstract
Peptide ligation is an indispensable step in the chemical synthesis of target peptides and proteins that are difficult to synthesize at once by a solid-phase synthesis. The ligation reaction is generally conducted with two peptide fragments at a high aqueous concentration to increase the reaction rate; however, this often causes unpredictable aggregation and precipitation of starting or resulting peptides due to their hydrophobicities. Here, we have developed a novel peptide ligation strategy harnessing the two intrinsic characteristics of oligodeoxynucleotides (ODNs), i.e., their hydrophilicity and hybridization ability, which allowed increases in the water solubility of peptides and the reaction kinetics due to the proximity effect, respectively. Peptide-ODN conjugates that can be cleaved to regenerate native peptide sequences were synthesized using novel lysine derivatives containing conjugation handles and photolabile linkers, via solid-phase peptide synthesis and subsequent conjugation to 15-mer ODNs. Two complementary conjugates were applied to carbodiimide-mediated peptide ligation on a DNA scaffold, and the subsequent DNA removal was conducted by photoirradiation in a traceless fashion. This DNA scaffold-assisted ligation resulted in a significant acceleration of the reaction kinetics and enabled ligation of a hydrophobic peptide at a micromolar concentration. On the basis of this chemistry, a simultaneous ligation of three different peptide fragments on two different DNA scaffolds has been conducted for the first time.

Abstract
Canaline (Can) is a non-proteinogenic amino acid containing an aminooxy group in its side chain. Can-containing peptides can be synthesized by standard Fmoc SPPS using Fmoc-Can(2-Cl-Trt). Here, for the first time, a Can residue within a peptide sequence was found to spontaneously cleave the main chain amide bond under slightly acidic conditions (pH 4-5). Contrastingly, Can-containing peptides are completely stable under the acidic conditions for HPLC purification (pH ca. 2) and under the neutral conditions for native chemical ligation (NCL). Taking advantage of these unique pH-dependent properties of Can, a novel solubilizing tag system for NCL-mediated protein synthesis using (Lys/Arg)n-Can was developed.
