Abstract
Although the desulfurization of thiols is a topic of great importance and has received significant attention, most efforts have focused on the hydrodesulfurization of thiols. In this work, we describe the desulfurization of thiols for nucleophilic substitution. This process occurs rapidly, promoted by the Ph3P/ICH2CH2I system, and can be extended to a wide range of nucleophiles. Notably, free amines can be employed as nucleophiles to synthesize various secondary and tertiary amines. This method tolerates a wide array of functional groups, including hydroxyl groups in amination reactions. Benzyl thiols are particularly reactive and can be completely converted at room temperature within 15 min. Although alkyl thiols show lower reactivity, they can also be converted smoothly at a reaction temperature of 70 °C overnight.

Abstract
Glycoconjugates are major constituents of mammalian cells that are formed via covalent conjugation of carbohydrates to other biomolecules like proteins and lipids and often expressed on the cell surfaces. Among the three major classes of glycoconjugates, proteoglycans and glycoproteins contain glycans linked to the protein backbone via amino acid residues such as Asn for N-linked glycans and Ser/Thr for O-linked glycans. In glycolipids, glycans are linked to a lipid component such as glycerol, polyisoprenyl pyrophosphate, fatty acid ester, or sphingolipid. Recently, glycoconjugates have become better structurally defined and biosynthetically understood, especially those associated with human diseases, and are accessible to new drug, diagnostic, and therapeutic developments. This review describes the status and new advances in the biological study and therapeutic applications of natural and synthetic glycoconjugates, including proteoglycans, glycoproteins, and glycolipids. The scope, limitations, and novel methodologies in the synthesis and clinical development of glycoconjugates including vaccines, glyco-remodeled antibodies, glycan-based adjuvants, glycan-specific receptor-mediated drug delivery platforms, etc., and their future prospectus are discussed.

Abstract
Chemical protein synthesis is a powerful avenue for accessing homogeneously modified proteins. While a significant number of small modified proteins bearing native post-translational modifications and non-natural modifications have been generated to date, access to larger targets has proved challenging. Herein, we describe the use of two ligation manifolds, namely, diselenide-selenoester ligation and native chemical ligation, to assemble a 31.5 kDa phosphorylated insulin-like growth factor binding protein (IGFBP-2) that comprises 290 amino acid residues, a phosphoserine post-translational modification, and nine disulfide bonds.

Abstract
Peptides and proteins can be either synthesized using solid-phase peptide synthesis (SPPS) or by applying a combination of SPPS and ligation approaches to address fundamental questions related to human health and disease, among others. The demand for their production either by chemical or biological methods continues to raise significant interests from the synthetic community. In this context, transition metals such as Pd, Ag, Hg, Tl, Au, Zn, Ni, and Cu have also contributed to the field of peptide and protein synthesis such as in peptide conjugation, extending native chemical ligation (NCL), and for regioselective disulfide bonds formation. In this review, we highlight, summarize, and evaluate the use of various transition metals in the chemical synthesis of peptides and proteins with emphasis on recent developments in this exciting research area.

Abstract
We report selective removals of N-terminal and internal Cys protecting groups using different palladium complexes to facilitate the efficient chemical protein synthesis. Utilizing the orthogonal deprotection pairs, we accomplished chemical synthesis of histone H3 containing trimethylated Lys through the combination of Pd(0)-mediated Alloc deprotection for one-pot multiple peptide ligation and Pd(II)Cl2-mediated Acm deprotection to recover native Cys residues after desulfurization.

Abstract
Here, we describe an Se-auxiliary mediated ligation protocol capable of rapid native chemical ligations at sterically hindered junctions, followed by in situ auxiliary cleavage under neutral conditions without affecting unprotected Cys residues. This auxiliary, which is prepared from phenyl acetaldehyde in one step, can be conveniently attached to the N-terminal region of a peptide via a reductive amination or coupling reaction. We demonstrated this methodology by synthesizing two protein samples.

Abstract
The translation of biological glycosylation in humans to the clinical applications involves systematic studies using homogeneous samples of oligosaccharides and glycoconjugates, which could be accessed by chemical, enzymatic or other biological methods. However, the structural complexity and wide-range variations of glycans and their conjugates represent a major challenge in the synthesis of this class of biomolecules. To help navigate within many methods of oligosaccharide synthesis, this Perspective offers a critical assessment of the most promising synthetic strategies with an eye on the therapeutically relevant targets.

Abstract
Selenocysteine, the selenium-containing analogue of cysteine, is the twenty-first proteinogenic amino acid. Since its discovery almost fifty years ago, it has been exploited in unnatural systems even more often than in natural systems. Selenocysteine chemistry has attracted the attention of many chemists in the field of chemical biology owing to its high reactivity and resulting potential for various applications such as chemical modification, chemical protein (semi)synthesis, and protein folding, to name a few. In this Minireview, we will focus on the chemistry of selenium and selenocysteine and their utility in protein chemistry.

Abstract
Chemical synthesis of histones allows precise control of the installation of post-translational modifications via the coupling of derivatized amino acids. Shortcomings of other approaches for obtaining modified histones for epigenetic studies include heterogeneity of the obtained product and difficulties in incorporating multiple modifications on the same histone. In this protocol, unprotected peptide fragments are prepared by Fmoc solid-phase synthesis and coupled in aqueous buffers via native chemical ligation (NCL; in NCL, a peptide bond is formed between a peptide with an N-terminal Cys and another peptide having a C-terminal thioester). This task is challenging, with obstacles relating to the preparation and ligation of hydrophobic peptides, as well as the requirement for multiple purification steps due to protecting-group manipulations during the polypeptide assembly process. To address this, our approach uses an easily removable solubilizing tag for the synthesis and ligation of hydrophobic peptides, as well as a more efficient and better-yielding method to remove Cys-protecting groups that uses palladium chemistry (specifically [Pd(allyl)Cl]2 and PdCl2 complexes). The utility of this approach is demonstrated in the syntheses of ubiquitinated H2B at Lys34, phosphorylated H2A at Tyr57 and unmodified H4. Each of these analogs can be prepared in milligram quantities within ∼20-30 d.

Abstract
Proteoglycans play critical roles in many biological events. Due to their structural complexities, strategies towards synthesis of this class of glycopeptides bearing well-defined glycan chains are urgently needed. In this work, we give the full account of the synthesis of syndecan-3 glycopeptide (53-62) containing two different heparan sulfate chains. For assembly of glycans, a convergent 3+2+3 approach was developed producing two different octasaccharide amino acid cassettes, which were utilized towards syndecan-3 glycopeptides. The glycopeptides presented many obstacles for post-glycosylation manipulation, peptide elongation, and deprotection. Following screening of multiple synthetic sequences, a successful strategy was finally established by constructing partially deprotected single glycan chain containing glycopeptides first, followed by coupling of the glycan-bearing fragments and cleavage of the acyl protecting groups.

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 .

Abstract
The acetamidomethyl (Acm) moiety is a widely used cysteine protecting group for the chemical synthesis and semisynthesis of peptide and proteins. However, its removal is not straightforward and requires harsh reaction conditions and additional purification steps before and after the removal step, which extends the synthetic process and reduces the overall yield. To overcome these shortcomings, a method for rapid and efficient Acm removal using Pd(II) complexes in aqueous medium is reported. We show, for the first time, the assembly of three peptide fragments in a one-pot fashion by native chemical ligation where the Acm moiety was used to protect the N-terminal Cys of the middle fragment. Importantly, an efficient synthesis of the ubiquitin-like protein UBL-5, which contains two native Cys residues, was accomplished through the one-pot operation of three key steps, namely ligation, desulfurization, and Acm deprotection, highlighting the great utility of the new approach in protein synthesis.

Abstract
The deselenization of selenocysteine selectively removes the selenol group to give alanine under anaerobic conditions or serine under aerobic conditions (oxygen saturation).
The development of native chemical ligation coupled with desulfurization has allowed ligation at several new ligation junctions. However, desulfurization also converts all cysteine residues in the protein sequence into alanine. Deselenization of selenocysteine, in contrast, selectively removes the selenol group to give alanine in the presence of unprotected cysteines. In this study we shed more light onto the deselenization mechanism of selenocysteine to alanine and provide optimized conditions for the reaction. The deselenization can be accomplished in one minute under anaerobic conditions to give alanine. Under aerobic conditions (oxygen saturation), selenocysteine is converted into serine.

Abstract
An ionic liquid-supported synthetic method for the construction of glycopeptides in high yields is reported. This method avoids the use of large excesses of reagents and chromatographic purification and, therefore, represents a useful addition to existing approaches for the ionic liquid-supported synthesis of oligosaccharides and peptides.

Abstract
With the study of peptides and proteins at the heart of many scientific endeavors, the omics era heralded a multitude of opportunities for chemists and biologists alike. Across the interface with life sciences, peptide chemistry plays an indispensable role, and progress made over the past decades now allows proteins to be treated as molecular patchworks stitched together through synthetic tailoring. The continuous elaboration of sophisticated strategies notwithstanding, Merrifield's solid-phase methodology remains a cornerstone of chemical protein design. Although the non-practitioner might misjudge peptide synthesis as trivial, routine, or dull given its long history, we comment here on its many advances, obstacles, and prospects from a practitioner's point of view. While sharing our perspectives through thematic highlights across the literature, this treatise provides an interpretive overview as a guide to novices, and a recap for specialists.

Abstract
One of the condensation methods for the preparation of long-chain peptides, the so-called thioester method requires protecting groups for amino and thiol groups for regioselective ligation. In this study, we demonstrated that the phenacyl (Pac) group acts as an efficient protecting group of cysteine side chains. We synthesized a cysteine derivative carrying the Pac group at the side chain sulfur atom, and Pac-containing peptides and peptide thioesters were synthesized using it by the ordinary 9-fluorenylmethoxycarbonyl (Fmoc)-based solid-phase peptide synthesis strategy. Pac-containing peptide segments could be condensed by the thioester method. After the condensation reaction, Pac groups could be removed by Zn/AcOH treatment. In addition, the azido group, which was used for the protection of lysine side chains, was simultaneously converted into an amino group, demonstrating that this protecting group scheme simplified the deprotecting reaction after the peptide condensation reaction to a single step.

Abstract
In order to link structural features on a molecular level to the function of chemokines, site-specific modification strategies are strongly required. These can be used to incorporate fluorescent dyes and/or physical probes to allow investigations in a wide range of biological and physical techniques, e.g., nuclear magnetic resonance (NMR) spectroscopy, fluorescence microscopy, fluorescence resonance energy transfer (FRET), or fluorescence correlation spectroscopy (FCS). Only a limited number of functional groups within the 20 canonical amino acids allow ligation strategies that can be helpful to introduce novel functionalities, which in turn expand the scope of chemoselective and orthogonal reactivity of (semi)synthetic chemokines. In the present chapter we mainly focus on the fabulous history of native chemical ligation (NCL) and provide a general protocol for the preparation of C-terminally modified SDF-1α including tips and tricks for practical work. We believe that this protocol can be easily adapted to other chemokines and many proteins in general.
