Abstract
Secretoglobin (SCGB) 3A2 belongs to an intriguing family of small, secreted proteins present only in mammals. Although members of the SCGB protein family have distinct amino acid sequences, they share structural similarities. Of particularly interest is the not yet fully understood self-assembly ability of SCGBs, which arise from covalent disulfide dimerization and non-covalent oligomerization. Recently, SCGB3A2 has attracted attention for its singular expression profile in airways. However, the knowledge on SCGB3A2 (patho)physiology derives exclusively from in vivo and complex ex vivo mixtures, which hampers characterization of the mechanisms driving SCGB3A2 structural behavior. Herein, we document the chemical synthesis of SCGB3A2 in multi-milligram quantities. Key to access both monomeric and homodimeric SCGB3A2 analogues was the use of KAHA ligation and enabled masking of the cysteine residue. The synthetic proteins were used to investigate the SCGB3A2 self-assembly profile, confirming their high propensity to dimerization even in the absence of the key Cys residue.

Abstract
An advanced insulin synthesis is presented that utilizes one-pot/stepwise disulfide bond formation enabled by acid-activated S-protected cysteine sulfoxides in the presence of chloride anion. S-chlorocysteine generated from cysteine sulfoxides reacts with an S-protected cysteine to afford S-sulfenylsulfonium cation, which then furnishes the disulfide or reversely returns to the starting materials depending on the S-protection employed and the reaction conditions. Use of S-acetamidomethyl cysteine (Cys(Acm)) and its sulfoxide (Cys(Acm)(O)) selectively give the disulfide under weak acid conditions in the presence of MgCl2 even if S-p-methoxybenzyl cysteine (Cys(MBzl)) and its sulfoxide (Cys(MBzl)(O)) are also present. In contrast, the S-MBzl pair yields the disulfide under more acidic conditions in the presence of a chloride anion source. These reaction conditions allowed a one-pot insulin synthesis. Additionally, lipidated insulin was prepared by a one-pot disulfide-bonding/lipidation sequence.

Diselenide-bond replacement of the external disulfide bond of insulin increases its oligomerization leading to sustained activity. Commun Chem 2023; 6:258.

Abstract
Seleno-insulin, a class of artificial insulin analogs, in which one of the three disulfide-bonds (S-S's) of wild-type insulin (Ins) is replaced by a diselenide-bond (Se-Se), is attracting attention for its unique chemical and physiological properties that differ from those of Ins. Previously, we pioneered the development of a [C7UA,C7UB] analog of bovine pancreatic insulin (SeIns) as the first example, and demonstrated its high resistance against insulin-degrading enzyme (IDE). In this study, the conditions for the synthesis of SeIns via native chain assembly (NCA) were optimized to attain a maximum yield of 72%, which is comparable to the in vitro folding efficiency for single-chain proinsulin. When the resistance of BPIns to IDE was evaluated in the presence of SeIns, the degradation rate of BPIns became significantly slower than that of BPIns alone. Furthermore, the investigation on the intermolecular association properties of SeIns and BPIns using analytical ultracentrifugation suggested that SeIns readily forms oligomers not only with its own but also with BPIns. The hypoglycemic effect of SeIns on diabetic rats was observed at a dose of 150 μg/300 g rat. The strategy of replacing the solvent-exposed S-S with Se-Se provides new guidance for the design of long-acting insulin formulations.

Abstract
Chemical protein synthesis can provide well-defined modified proteins. Herein, we report the chemical synthesis of plant-derived cysteine-rich secretory proteins and late-stage derivatization of the synthetic proteins. The syntheses were achieved with distinct chemoselective amide bond forming reactions - EPF2 by native chemical ligation (NCL), epidermal patterning factor (EPF) 1 by the α-ketoacid-hydroxylamine (KAHA) ligation, and fluorescent functionalization of their folded variants by potassium acyltrifluoroborate (KAT) ligation. The chemically synthesized EPFs exhibit bioactivity on stomatal development in Arabidopsis thaliana. Comprehensive synthesis of EPF derivatives allowed us to identify suitable fluorescent variants for bioimaging of the subcellar localization of EPFs.

Abstract
AbstractThe modification of native peptides to peptidomimetics is an important goal in medicinal chemistry and requires, in many cases, the integration of C-acylation steps involving amino acids with classical peptide synthesis. Many classical C-acylation protocols involving Claisen condensations and the use of ylides are not compatible with peptide synthesis, mostly due to the requirements for strong bases leading to epimerization or deprotection of peptides. Meldrum’s acid as well as several specific phosphorus and sulfur ylides, however, are acidic enough to provide reactive C-nucleophiles under mildly basic conditions tolerated during peptide synthesis. This review provides an overview of peptide-compatible C-acylations using Meldrum’s acid and phosphorus and sulfur ylides, and their application in the medicinal chemistry of peptides.1 Introduction2 C-Acylation of Meldrum’s Acid2.1 C-Acylation of Meldrum’s Acid on Solid Phase3 Ylides as Substrates for C-Acylation3.1 C-Acylation of Phosphorus Ylides in Solution Phase3.2 C-Acylation of Solid-Supported Phosphorus Ylides3.3 C-Acylation of Sulfur Ylides3.4 C-Acylation of Solid-Supported Sulfur Ylides4 Miscellaneous Ylides as Acyl Anion Equivalents5 Summary

Abstract
The synthesis of secreted cysteine-rich proteins (CRPs) is a long-standing challenge due to protein aggregation and premature formation of inter- and intramolecular disulfide bonds. Chemical synthesis provides reduced CRPs with a higher purity, which is advantageous for folding and isolation. Herein, we report the chemical synthesis of pollen tube attractant CRPs Torenia fournieri LURE (TfLURE) and Torenia concolor LURE (TcLURE) and their chimeric analogues via α-ketoacid-hydroxylamine (KAHA) ligation. The bioactivity of chemically synthesized TfLURE protein was shown to be comparable to E. coli expressed recombinant protein through in vitro assay. The convergent protein synthesis approach is beneficial for preparing these small protein variants efficiently. A convergent chemical synthesis was established for Torenia plant pollen tube attractant proteins, LUREs and their chimeric analogues by KAHA ligation. The synthetic TfLURE showed comparable bioactivity with E.coli expressed recombinant protein.![]()

Abstract
Amide linkage of glycine-amino acid was synthesized by coupling of substituted 2-(aminomethyl)malononitrile as a C-terminal glycine unit and N-terminal amine using CsOAc and O2 in an aqueous solution. This is a coupling reagent-free and catalyst-free peptide synthesis via oxidative amide bond formation. Various tripeptides and tetrapeptides were synthesized efficiently and the sulfide moiety is inert even under an oxygen atmosphere.

Abstract
The pancreatic peptide hormone insulin, first discovered exactly 100 years ago, is essential for glycemic control and is used as a therapeutic for the treatment of type 1 and, increasingly, type 2 diabetes. With a worsening global diabetes epidemic and its significant health budget imposition, there is a great demand for new analogues possessing improved physical and functional properties. However, the chemical synthesis of insulin's intricate 51-amino acid, two-chain, three-disulfide bond structure, together with the poor physicochemical properties of both the individual chains and the hormone itself, has long represented a major challenge to organic chemists. This review provides a timely overview of the past efforts to chemically assemble this fascinating hormone using an array of strategies to enable both correct folding of the two chains and selective formation of disulfide bonds. These methods not only have contributed to general peptide synthesis chemistry and enabled access to the greatly growing numbers of insulin-like and cystine-rich peptides but also, today, enable the production of insulin at the synthetic efficiency levels of recombinant DNA expression methods. They have led to the production of a myriad of novel analogues with optimized structural and functional features and of the feasibility for their industrial manufacture.

Abstract
Chemical protein synthesis allows the construction of well-defined structural variations and facilitates the development of deeper understanding of protein structure-function relationships and new protein engineering strategies. Herein, we report the chemical synthesis of interleukin-2 (IL-2) variants on a multimilligram scale and the formation of non-natural disulfide mimetics that improve stability against reduction. The synthesis was accomplished by convergent KAHA ligations; the acidic conditions of KAHA ligation proved to be valuable for the solubilization of the hydrophobic segments of IL-2. The bioactivity of the synthetic IL-2 and its analogues were shown to be equipotent to recombinant IL-2 and exhibit improved stability against reducing agents.

Abstract
Insulin has been a life-saving drug for millions of people with diabetes. However, several challenges exist which limit therapeutic benefits and reduce patient convenience. One key challenge is the fibrillation propensity, which necessitates refrigeration for storage. To address this limitation, we chemically synthesized and evaluated a methylene thioacetal human insulin analogue (SCS-Ins). The synthesized SCS-Ins showed enhanced serum stability and aggregation resistance while retaining bioactivity compared with native insulin.

Abstract
E2 conjugating enzymes are the key catalytic actors in the transfer of ubiquitin, SUMO, and other ubiquitin-like modifiers to their substrate proteins. Their high rates of transfer and promiscuous binding complicate studies of their interactions and binding partners. To access specific, covalently linked conjugates of the SUMO E2 conjugating enzyme Ubc9, we prepared synthetic variants bearing site-specific non-native modifications including the following: (1) replacement of Cys93 to 2,3-diaminopropionic acid to form the amide-linked stable E2-SUMO conjugate, which is known to have high affinity for E3 ligases; (2) a photoreactive group (diazirine) to trap E3 ligases upon UV irradiation; and (3) an N-terminal biotin for purification and detection. To construct these Ubc9 variants in a flexible, convergent manner, we combined the three leading methods: native chemical ligation (NCL), α-ketoacid-hydroxylamine (KAHA) ligation, and serine/threonine ligation (STL). Using the synthetic proteins, we demonstrated the selective formation of Ubc9-SUMO conjugates and the trapping of an E3 ligase (RanBP2) to form the stable, covalently linked SUMO1-Ubc9-RanBP2 ternary complex. The powerful combination of ligation methods-which minimizes challenges of functional group manipulations-will enable chemical probes based on E2 conjugating enzymes to trap E3 ligases and facilitate the synthesis of other protein classes.
