Abstract
Peptide cyclization is often used to introduce conformational rigidity and to enhance the physiological stability of the peptide. This study presents a novel late-stage cyclization method for creating thioketal cyclic peptides from bis-cysteine peptides and drugs. Symmetrical cyclic ketones and acetone were found to react with bis-cysteine unprotected peptides efficiently to form thioketal linkages in trifluoroacetic acid (TFA) without any other additive. The attractive features of this method include high chemoselectivity, operational simplicity, and robustness. In addition, TFA as the reaction solvent can dissolve any unprotected peptide. As a showcase, the dimethyl thioketal versions of lanreotide and octreotide were prepared and evaluated, both of which showed much improved reductive stability and comparable activity.

Abstract
The addition of a sulfhydryl group to water-soluble N-alkyl(o-nitrostyryl)pyridinium ions (NSPs) followed by fast and irreversible cyclization and aromatization results in a stable S-C sp2-bond. The reaction sequence, termed Click & Lock, engages accessible cysteine residues under the formation of N-hydroxy indole pyridinium ions. The accompanying red shift of >70 nm to around 385 nm enables convenient monitoring of the labeling yield by UV-vis spectroscopy at extinction coefficients of ≥2 × 104 M-1 cm-1. The versatility of the linker is demonstrated in the stapling of peptides and the derivatization of proteins, including the modification of reduced trastuzumab with Val-Cit-PAB-MMAE. The high stability of the linker in human plasma, fast reaction rates (k app up to 4.4 M-1 s-1 at 20 °C), high selectivity for cysteine, favorable solubility of the electrophilic moiety and the bathochromic properties of the Click & Lock reaction provide an appealing alternative to existing methods for cysteine conjugation.

Abstract
Chemoselective modification of specific residues within a given protein poses a significant challenge, as the microenvironment of amino acid residues in proteins is variable. Developing a universal molecular platform with tunable chemical warheads can provide powerful tools for precisely labeling specific amino acids in proteins. Cysteine and lysine are hot targets for chemoselective modification, but current cysteine/lysine-selective warheads face challenges due to cross-reactivity and unstable reaction products. In this study, a versatile fluorescent platform is developed for highly selective modification of cysteine/lysine under biocompatible conditions. Chloro- or phenoxy-substituted NBSe derivatives effectively labeled cysteine residues in the cellular proteome with high specificity. This finding also led to the development of phenoxy-NBSe phototheragnostic for the diagnosis and activatable photodynamic therapy of GSH-overexpressed cancer cells. Conversely, alkoxy-NBSe derivatives are engineered to selectively react with lysine residues in the cellular environment, exhibiting excellent anti-interfering ability against thiols. Leveraging a proximity-driven approach, alkoxy-NBSe probes are successfully designed to demonstrate their utility in bioimaging of lysine deacetylase activity. This study also achieves integrating a small photosensitizer into lysine residues of proteins in a regioselective manner, achieving photoablation of cancer cells activated by overexpressed proteins.

Abstract
Simple 1-phenylpropynones undergo a selective double thia-Michael addition with thiols in buffered media, yielding an interesting dithioacetal linkage joining two thiols. The reactivity of various Michael-alkyne reagents is compared in this chemoselective, atom economical, and non-oxidative cross-linking of two thiols. The stability and chemical reactivity of the dithioacetal links are studied, and the utility of the disulfide targeting bioconjugation methodology is shown by the selective rebridging of native cyclic peptides after the reductive cleavage of their disulfide bridge.

Abstract
Peptide-based covalent probes can target shallow protein surfaces not typically addressable using small molecules, yet there is a need for versatile approaches to convert native peptide sequences into covalent binders that can target a broad range of residues. Here we report protein-based thio-methacrylate esters-electrophiles that can be installed easily on unprotected peptides and proteins via cysteine side chains, and react efficiently and selectively with cysteine and lysine side chains on the target. Methacrylate phosphopeptides derived from 14-3-3-binding proteins irreversibly label 14-3-3σ via either lysine or cysteine residues, depending on the position of the electrophile. Methacrylate peptides targeting a conserved lysine residue exhibit pan-isoform binding of 14-3-3 proteins both in lysates and in extracellular media. Finally, we apply this approach to develop protein-based covalent binders. A methacrylate-modified variant of the colicin E9 immunity protein irreversibly binds to the E9 DNAse, resulting in significantly higher thermal stability relative to the non-covalent complex. Our approach offers a simple and versatile route to convert peptides and proteins into potent covalent binders.

Click'n lock: rapid exchange between unsymmetric tetrazines and thiols for reversible, chemoselective functionalisation of biomolecules with on-demand bioorthogonal locking.

Abstract
The late-stage functionalisation and diversification of complex structures including biomolecules is often achieved with the help of click chemistry. Besides employing irreversible click-like reactions, many synthetic applications benefit from reversible click reaction strategies, so called de-/trans-click approaches. Yet, the combination of both, reversible and irreversible click chemistry - while still respecting the stringent criteria of click transformations - remains so far elusive for modifications of biomolecular structures. Here, we report click'n lock as a concept that enables reversible click reactions and on-demand locking of chemical entities, thus switching from reversible to irreversible modifications of complex biomolecules. For this purpose, we employ the tetrazine-thiol exchange (TeTEx) reaction as a fully traceless click reaction with second order rate constants k2 higher than 2 M-1 s-1 within aqueous environments. Employing TeTEx as a reversible click reaction for the chemoselective modification of biomolecules is made possible by the use of 3,6-disubstituted 1,2,4,5-tetrazines bearing a single sulfide residue. The inherent reactivity of tetrazines towards inverse electron demand Diels-Alder (IEDDA) reactions allows to stabilize the clicked structure, switching from reversible to irreversible systems (click'n lock).

Abstract
Site-selective disulfide rebridging has emerged as a powerful strategy to modulate the structural and functional properties of proteins. Here, we introduce a novel class of electrophilic reagents, designated oxSTEF, that demonstrate excellent efficiency in disulfide rebridging via double thiol exchange. The oxSTEF reagents are prepared using an efficient synthetic sequence which may be diverted to obtain a range of derivatives allowing for tuning of reactivity or steric bulk. We demonstrate highly selective rebridging of cyclic peptides and native proteins, such as human growth hormone, and the absence of cross-reactivity with other nucleophilic amino acid residues. The oxSTEF conjugates undergo glutathione-mediated disintegration under tumor-relevant glutathione concentrations, which highlights their potential for use in targeted drug delivery. Finally, the α-dicarbonyl motif of the oxSTEF reagents enables "second phase" oxime ligation, which furthermore increases the thiol stability of the conjugates significantly.

Abstract
Bioconjugation, a synthetic tool that endows small molecules with biocompatibility and target specificity through covalent attachment of a biomolecule, holds promise for next-generation diagnosis or therapy. Besides the establishment of chemical bonding, such chemical modification concurrently allows alteration of the physicochemical properties of small molecules, but this has been paid less attention in designing novel bioconjugates. Here, we report a "two birds one stone" methodology for irreversible porphyrin bioconjugation based on β-fluoropyrrolyl-cysteine SNAr chemistry, in which the β-fluorine of porphyrin is selectively replaced by a cysteine in either peptides or proteins to generate novel β-peptidyl/proteic porphyrins. Notably, due to the distinct electronic nature between fluorine and sulfur, such replacement makes the Q band red-shift to the near-infrared region (NIR, >700 nm). This facilitates intersystem crossing (ISC) to enhance the triplet population and thus singlet oxygen production. This new methodology features water tolerance, a fast reaction time (15 min), good chemo-selectivity, and broad substrate scope, including various peptides and proteins under mild conditions. To demonstrate its potential, we applied porphyrin β-bioconjugates in several scenarios, including (1) cytosolic delivery of functional proteins, (2) metabolic glycan labeling, (3) caspase-3 detection, and (4) tumor-targeting phototheranostics.

Abstract
Selective reaction of diphenylcyclopropenone (DPCP) and 1,2-aminothiol in water at pH 7.4 produces an amide conjugate with the release of thiol. In addition, structural modifications of DPCP enable the coupling rate to be tuned with a reaction constant of +3.68. Based on this chemistry, triple labelling was demonstrated by treating an N-terminal cysteine peptide with DPCP-Cl followed by thiol-maleimide and tyrosine-diazonium couplings in one pot. We anticipate that the DPCP motif will be a useful toolkit for multiple bioconjugation.

Abstract
The complex social ecosystem regulates the spectrum of human behavior. However, it becomes relatively easier to understand if we disintegrate the contributing factors, such as locality and interacting partners. Interestingly, it draws remarkable similarity with the behavior of a residue placed in a social setup of functional groups in a protein. Can it inspire principles for creating a unique environment for the precision engineering of proteins? We demonstrate that localization-regulated interacting partner(s) could render precise and traceless single-site modification of structurally diverse native proteins. The method targets a combination of high-frequency Lys residues through an array of reversible and irreversible reactions. However, excellent simultaneous control over chemoselectivity, site selectivity, and modularity ensures that the user-friendly protocol renders acyl group installation, including post-translational modifications (PTMs), on a single Lys. Besides, it offers a chemically orthogonal handle for the installation of probes. Also, a purification protocol integration delivers analytically pure single-site tagged protein bioconjugates. The precise labeling of a surface Lys residue ensures that the structure and enzymatic activities remain conserved post-bioconjugation. For example, the precise modification of insulin does not affect its uptake and downstream signaling pathway. Further, the method enables the synthesis of homogeneous antibody-fluorophore and antibody-drug conjugates (AFC and ADC; K183 and K249 labeling). The trastuzumab-rhodamine B conjugate displays excellent serum stability along with antigen-specific cellular imaging. Further, the trastuzumab-emtansine conjugate offers highly specific antiproliferative activity toward HER-2 positive SKBR-3 breast cancer cells. This work validates that disintegrate theory can create a comprehensive platform to enrich the chemical toolbox to meet the technological demands at the chemistry, biology, and medicine interface.

Abstract
Chalcogen-centered cascade exchange chemistry is increasingly understood to account for thiol-mediated uptake, that is, the ability of reversibly thiol-reactive agents to penetrate cells. Here, reversible Michael acceptors are shown to enable and inhibit thiol-mediated uptake, including the cytosolic delivery of proteins. Dynamic cyano-cinnamate dimers rival the best chalcogen-centered inhibitors. Patterns generated in inhibition heatmaps reveal contributions from halogen-bonding switches that occur independent from the thyroid transporter MCT8. The uniqueness of these patterns supports that the entry of tetrel-centered exchangers into cells differs from chalcogen-centered systems. These results expand the chemical space of thiol-mediated uptake and support the existence of a universal exchange network to bring matter into cells, abiding to be decoded for drug delivery and drug discovery in the broadest sense.

Abstract
Cysteine bioconjugation serves as a powerful tool in biological research and has been widely used for chemical modification of proteins, constructing antibody-drug conjugates, and enabling cell imaging studies. Cysteine conjugation reactions with fast kinetics and exquisite selectivity have been under heavy pursuit as they would allow clean protein modification with just stoichiometric amounts of reagents, which minimizes side reactions, simplifies purification and broadens functional group tolerance. In this concept, we summarize the recent advances in fast cysteine bioconjugation, and discuss the mechanism and chemical principles that underlie the high efficiencies of the newly developed cysteine reactive reagents.

Abstract
Tools that facilitate the chemical modification of peptides and proteins are gaining an increasing amount of interest across many avenues of chemical biology as they enable a plethora of therapeutic, imaging and diagnostic applications. Cysteine residues and disulfide bonds have been highlighted as appealing targets for modification due to the highly homogenous nature of the products that can be formed through their site-selective modification. Amongst the reagents available for the site-selective modification of cysteine(s)/disulfide(s), pyridazinediones (PDs) have played a particularly important and enabling role. In this review, we outline the unique chemical features that make PDs especially well-suited to cysteine/disulfide modification on a wide variety of proteins and peptides, as well as provide context as to the problems solved (and applications enabled) by this technology.

Abstract
The development of divinylpyrimidine (DVP) reagents for the synthesis of antibody-drug conjugates (ADCs) with in vivo efficacy and tolerability is reported. Detailed structural characterisation of the synthesised ADCs was first conducted followed by in vitro and in vivo evaluation of the ADCs' ability to safely and selectively eradicate target-positive tumours.
