Abstract
Bioorthogonal click chemistry has played a transformative role in many research fields, including chemistry, biology, and medicine. Click reactions are crucial to produce increasingly complex bioconjugates, to visualize and manipulate biomolecules in living systems and for various applications in bioengineering and drug delivery. As biological (model) systems grow more complex, researchers have an increasing need for using multiple orthogonal click reactions simultaneously. In this review, we will introduce the most common bioorthogonal reactions and discuss their orthogonal use on the basis of their mechanism and electronic or steric tuning. We provide an overview of strategies to create reaction orthogonality and show recent examples of mutual orthogonal chemistry used for simultaneous biomolecule labeling. We end by discussing some considerations for the type of chemistry needed for labeling biomolecules in a system of choice.

Abstract
Organoboron compounds have a wide range of applications in numerous research fields, and methods to incorporate them in biomolecules are much sought after. Here, on-resin chemical syntheses of aliphatic and vinylogous peptide boronic acids are presented by transition metal-catalyzed late-stage hydroboration of alkene and alkyne groups in peptides and peptoids, for example on allyl- and propargylglycine residues, using readily available chemicals. These methods yield peptide boronic acids with much shorter linkers than previously reported on-resin methods. Furthermore, the methods are regio- and stereoselective, compatible with all canonical amino acid residues and can be applied to short, long, and in part even "difficult" peptide sequences. In a feasibility study, the protected peptide vinylboronic acids are further derivatized by the Petasis reaction using salicylaldehyde derivatives. The ability of the obtained peptide boronic acids to reversibly bind to carbohydrates is demonstrated in a catch-release model experiment using a fluorescently labeled peptide boronic acid on cross-linked dextran beads. In summary, this highlights the potential of the target compounds for drug discovery, glycan-specific target recognition, controlled release, and diagnostics.

Abstract
The desire to create biomolecules modified with functionalities that go beyond nature's toolbox has resulted in the development of biocompatible and selective methodologies and reagents, each with different scope and limitations. In this overview, we highlight recent advances in the field of bioconjugation from 2016 to 2023. First, (metal-mediated) protein functionalization by exploiting the specific reactivity of amino acids will be discussed, followed by novel bioorthogonal reagents for bioconjugation of modified biomolecules.

Abstract
We report the development of a C(sp3 )-C(sp2 ) coupling reaction using styrene boronic acids and redox-active esters under photoredox catalysis. The reaction proceeds through an unusual polarity-mismatched radical addition mechanism that is orthogonal to established processes. Synergistic activation of the radical precursor and organoboron are critical mechanistic events. Activation of an N-hydroxyphthalimide (NHPI) ester by coordination to boron enables electron transfer, with decomposition leading to a nucleofuge rebound, activating the organoboron to radical addition. The unique mechanism enables chemoselective coupling of styrene boronic acids in the presence of other alkene radical acceptors. The scope and limitations of the reaction, and a detailed mechanistic investigation are presented.

Abstract
Bioorthogonal chemistry involves selective biocompatible reactions between functional groups that are not normally present in biology. It has been used to probe biomolecules in living systems, and has advanced biomedical strategies such as diagnostics and therapeutics. In this review, the challenges and opportunities encountered when translating in vitro bioorthogonal approaches to in vivo settings are presented, with a focus on methods to deliver the bioorthogonal reaction components. These methods include metabolic bioengineering, active targeting, passive targeting, and simultaneously used strategies. The suitability of bioorthogonal ligation reactions and bond cleavage reactions for in vivo applications is critically appraised, and practical considerations such as the optimum scheduling regimen in pretargeting approaches are discussed. Finally, we present our own perspectives for this area and identify what, in our view, are the key challenges that must be overcome to maximise the impact of these approaches.

Abstract
Small molecules remain an important category of therapeutic agents. Their binding to different proteins can lead to both desired and undesired biological effects. Identification of the proteins that a drug binds to has become an important step in drug development because it can lead to safer and more effective drugs. Parent bioactive molecules can be converted to appropriate probes that allow for visualization and identification of their target proteins. Typically, these probes are designed and synthesized utilizing some or all of five major tools; a photoactivatable group, a reporter tag, a linker, an affinity tag, and a bioorthogonal handle. This review covers two of the most challenging tools, photoactivation and bioorthogonal ligation. We provide a historical and theoretical background along with synthetic routes to prepare them. In addition, the review provides comparative analyses of the available tools that can assist decision making when designing such probes. A survey of most recent literature reports is included as well to identify recent trends in the field.

Abstract
Bioorthogonal chemistry is a set of methods using the chemistry of non-native functional groups to explore and understand biology in living organisms. In this review, we summarize the most common reactions used in bioorthogonal methods, their relative advantages and disadvantages, and their frequency of occurrence in the published literature. We also briefly discuss some of the less common but potentially useful methods. We then analyze the bioorthogonal-related publications in the CAS Content Collection to determine how often different types of biomolecules such as proteins, carbohydrates, glycans, and lipids have been studied using bioorthogonal chemistry. The most prevalent biological and chemical methods for attaching bioorthogonal functional groups to these biomolecules are elaborated. We also analyze the publication volume related to different types of bioorthogonal applications in the CAS Content Collection. The use of bioorthogonal chemistry for imaging, identifying, and characterizing biomolecules and for delivering drugs to treat disease is discussed at length. Bioorthogonal chemistry for the surface attachment of proteins and in the use of modified carbohydrates is briefly noted. Finally, we summarize the state of the art in bioorthogonal chemistry and its current limitations and promise for its future productive use in chemistry and biology.

Abstract
Pyridazines are important scaffolds for medicinal chemistry or crop protection agents, yet the selective preparation of 3-bromo-pyridazines with high regiocontrol remains difficult. We achieved the Lewis acid-mediated inverse electron demand Diels-Alder reaction between 3-monosubstituted s-tetrazine and silyl enol ethers and obtained functionalized pyridazines. In the case of 1-monosubstituted silyl enol ethers, exclusive regioselectivity was observed. Downstream functionalization of the resulting 3-bromo-pyridazines was demonstrated utilizing several cross-coupling protocols to synthesize 3,4-disubstituted pyridazines with excellent control over the substitution pattern.

Abstract
Boronic acids can play diverse roles when applied in biological environments, and employing boronic acid structures in tandem could provide new tools for multifunctional probes. This Letter describes a pair of boronic acid functional groups, 2-nitro-arylboronic acid (NAB) and (E)-alkenylboronic acid (EAB), that enable sequential cross-coupling through stepwise nickel- and copper-catalyzed processes. The selective coupling of NAB groups enables the preparation of stapled peptides, protein-protein conjugates, and other bioconjugates.

Abstract
![]()
Strained
alkenes and alkynes are the predominant dienophiles used
in inverse electron demand Diels–Alder (IEDDA) reactions. However,
their instability, cross-reactivity, and accessibility are problematic.
Unstrained dienophiles, although physiologically stable and synthetically
accessible, react with tetrazines significantly slower relative to
strained variants. Here we report the development of potassium arylethynyltrifluoroborates
as unstrained dienophiles for fast, chemically triggered IEDDA reactions.
By varying the substituents on the tetrazine (e.g., pyridyl- to benzyl-substituents),
cycloaddition kinetics can vary from fast (k2 = 21 M–1 s–1) to no reaction
with an alkyne-BF3 dienophile. The reported system was
applied to protein labeling both in the test tube and fixed cells
and even enabled mutually orthogonal labeling of two distinct proteins.

Abstract
Prodrugs, which remain inert until they are activated under appropriate conditions at the target site, have emerged as an attractive alternative to drugs that lack selectivity and show off-target effects. Prodrugs have traditionally been activated by enzymes, pH or other trigger factors associated with the disease. In recent years, bioorthogonal chemistry has allowed the creation of prodrugs that can be chemically activated with spatio-temporal precision. In particular, tetrazine-responsive bioorthogonal reactions can rapidly activate prodrugs with excellent biocompatibility. This review summarized the recent development of tetrazine bioorthogonal cleavage reaction and great promise for prodrug systems.

Abstract
The emergence of bioorthogonal reactions has greatly advanced research in the fields of biology and medicine. They are not only valuable for labeling, tracking, and understanding biomolecules within living organisms, but also important for constructing advanced bioengineering and drug delivery systems. As the systems studied are increasingly complex, the simultaneous use of multiple bioorthogonal reactions is equally desirable. In this review, we take a look at the different bioorthogonal reactions that have recently been developed, the methods of cellular incorporation and the strategies to create orthogonality within the bioorthogonal landscape.

Abstract
Bioorthogonal chemistries enable researchers to interrogate biomolecules in living systems. These reactions are highly selective and biocompatible and can be performed in many complex environments. However, like any organic transformation, there is no perfect bioorthogonal reaction. Choosing the "best fit" for a desired application is critical. Correspondingly, there must be a variety of chemistries-spanning a spectrum of rates and other features-to choose from. Over the past few years, significant strides have been made towards not only expanding the number of bioorthogonal chemistries, but also fine-tuning existing reactions for particular applications. In this Review, we highlight recent advances in bioorthogonal reaction development, focusing on how physical organic chemistry principles have guided probe design. The continued expansion of this toolset will provide more precisely tuned reagents for manipulating bonds in distinct environments.

Abstract
Bioorthogonal chemistry has offered an invaluable reactivity-based tool to chemical biology owing to its exquisite specificity in tagging a diverse set of biomolecules in their native environment. Despite tremendous progress in the field over the past decade, designing a suitable bioorthogonal chemical probe to investigate a given biological system remains a challenge. In this Perspective, we put forward a series of fitness factors that can be used to assess the performance of bioorthogonal chemical probes. The consideration of these criteria should encourage continuous innovation in bioorthogonal probe development as well as enhance the quality of biological data.

Abstract
Conformationally strained trans-cyclooctenes (TCOs) engage in bioorthogonal reactions with tetrazines with second order rate constants that can exceed 106 M-1s-1. The goal of this study was to provide insight into the stability of TCO reagents and to develop methods for stabilizing TCO reagents for long-term storage. The radical inhibitor Trolox suppresses TCO isomerization under high thiol concentrations and TCO shelf-life can be greatly extended by protecting them as stable Ag(I) metal complexes. 1H NMR studies show that Ag-complexation is thermodynamically favorable but the kinetics of dissociation are very rapid, and TCO•AgNO3 complexes are immediately dissociated upon addition of NaCl which is present in high concentration in cell media. The AgNO3 complex of a highly reactive s-TCO-TAMRA conjugate was shown to label a protein-tetrazine conjugate in live cells with faster kinetics and similar labeling yield relative to a 'traditional' TCO-TAMRA conjugate.

Abstract
Click chemistry has great potential for use in binding between nucleic acids, lipids, proteins, and other molecules, and has been used in many research fields because of its beneficial characteristics, including high yield, high specificity, and simplicity. The recent development of copper-free and less cytotoxic click chemistry reactions has allowed for the application of click chemistry to the field of medicine. Moreover, metabolic glycoengineering allows for the direct modification of living cells with substrates for click chemistry either in vitro or in vivo. As such, click chemistry has become a powerful tool for cell transplantation and drug delivery. In this review, we describe some applications of click chemistry for cell engineering in cell transplantation and for drug delivery in the diagnosis and treatment of diseases.

Abstract
We have quantum chemically explored the Diels-Alder reactivities of a systematic series of hetero-1,3-butadienes with ethylene by using density functional theory at the BP86/TZ2P level. Activation strain analyses provided physical insight into the factors controlling the relative cycloaddition reactivity of aza- and oxa-1,3-butadienes. We find that dienes with a terminal heteroatom, such as 2-propen-1-imine (NCCC) or acrolein (OCCC), are less reactive than the archetypal 1,3-butadiene (CCCC), primarily owing to weaker orbital interactions between the more electronegative heteroatoms with ethylene. Thus, the addition of a second heteroatom at the other terminal position (NCCN and OCCO) further reduces the reactivity. However, the introduction of a nitrogen atom in the backbone (CNCC) leads to enhanced reactivity, owing to less Pauli repulsion resulting from polarization of the diene HOMO in CNCC towards the nitrogen atom and away from the terminal carbon atom. The Diels-Alder reactions of ethenyl-diazene (NNCC) and 1,3-diaza-butadiene (NCNC), which contain heteroatoms at both the terminal and backbone positions, are much more reactive due to less activation strain compared to CCCC.

Abstract
![]()
Bioorthogonal
reactions are selective transformations that are
not affected by any biological functional group and are widely used
for chemical modification of biomolecules. Recently, we reported that
vinylboronic acids (VBAs) gave exceptionally high reaction rates in
the bioorthogonal inverse electron-demand Diels–Alder (iEDDA)
reaction with tetrazines bearing a boron-coordinating pyridyl moiety
compared to tetrazines lacking such a substituent. In this integrated
experimental and theoretical study, we show how the reaction rate
of the VBA-tetrazine ligation can be accelerated by shifting the equilibrium
from boronic acid to the boronate anion in the reaction mixture. Quantum
chemical activation strain analyses reveal that this rate enhancement
is a direct consequence of the excellent electron-donating capability
of the boronate anion in which the π HOMO is pushed to a higher
energy due to the net negative potential of this species. We have
explored the second-order rate constants of several tetrazines containing
potential VBA-coordinating hydroxyl substituents. We observed an increase
in rate constants of several orders of magnitude compared to the tetrazines
lacking a hydroxyl substituent. Furthermore, we find the hydroxyl-substituted
tetrazines to be more selective toward VBAs than toward the commonly
used bioorthogonal reactant norbornene, and more stable in aqueous
environment than the previously studied tetrazines containing a pyridyl
substituent.

Abstract
Controlled activation is a critical component in prodrug development. Here we report a concentration-sensitive platform approach for bioorthogonal prodrug activation by taking advantage of reaction kinetics. Using two 'click and release' systems, we demonstrate enrichment and prodrug activation specifically in mitochondria to demonstrate the principle of the approach. In both cases, the payload (doxorubicin or carbon monoxide) was released inside the mitochondrial matrix following the enrichment-initiated click reaction. Furthermore, mitochondria-targeted delivery yielded substantial augmentation of functional biological and therapeutic effects in vitro and in vivo when compared to controls, which did not result in enrichment. This method is thus a platform for targeted drug delivery that is amenable to conjugation with a variety of molecules and is not limited to cell-surface delivery. Taken together, these two 'click and release' pairs clearly demonstrate the concept of enrichment-triggered drug release and the critical feasibility of treating clinically relevant diseases such as acute liver injury and cancer.

Abstract
Chemical tools are transforming our understanding of biomolecules and living systems. Included in this group are bioorthogonal reagents-functional groups that are inert to most biological species, but can be selectively ligated with complementary probes, even in live cells and whole organisms. Applications of these tools have revealed fundamental new insights into biomolecule structure and function-information often beyond the reach of genetic approaches. In many cases, the knowledge gained from bioorthogonal probes has enabled new questions to be asked and innovative research to be pursued. Thus, the continued development and application of these tools promises to both refine our view of biological systems and facilitate new discoveries. Despite decades of achievements in bioorthogonal chemistry, limitations remain. Several reagents are too large or insufficiently stable for use in cellular environments. Many bioorthogonal groups also cross-react with one another, restricting them to singular tasks. In this Account, we describe our work to address some of the voids in the bioorthogonal toolbox. Our efforts to date have focused on small reagents with a high degree of tunability: cyclopropenes, triazines, and cyclopropenones. These motifs react selectively with complementary reagents, and their unique features are enabling new pursuits in biology. The Account is organized by common themes that emerged in our development of novel bioorthogonal reagents and reactions. First, natural product structures can serve as valuable starting points for probe design. Cyclopropene, triazine, and cyclopropenone motifs are all found in natural products, suggesting that they would be metabolically stable and compatible with a variety of living systems. Second, fine-tuning bioorthogonal reagents is essential for their successful translation to biological systems. Different applications demand different types of probes; thus, generating a collection of tools that span a continuum of reactivities and stabilities remains an important goal. We have used both computational analyses and mechanistic studies to guide the optimization of various cyclopropene and triazine probes. Along the way, we identified reagents that are chemoselective but best suited for in vitro work. Others are selective and robust enough for use in living organisms. The last section of this Account highlights the need for the continued pursuit of new reagents and reactions. Challenges exist when bioorthogonal chemistries must be used in concert, given that many exploit similar mechanisms and cannot be used simultaneously. Such limitations have precluded certain multicomponent labeling studies and other biological applications. We have relied on mechanistic and computational insights to identify mutually orthogonal sets of reactions, in addition to exploring unique genres of reactivity. The continued development of mechanistically distinct, biocompatible reactions will further diversify the bioorthogonal reaction portfolio for examining biomolecules.

Abstract
The emerging inverse electron demand Diels-Alder (IEDDA) reaction stands out from other bioorthogonal reactions by virtue of its unmatchable kinetics, excellent orthogonality and biocompatibility. With the recent discovery of novel dienophiles and optimal tetrazine coupling partners, attention has now been turned to the use of IEDDA approaches in basic biology, imaging and therapeutics. Here we review this bioorthogonal reaction and its promising applications for live cell and animal studies. We first discuss the key factors that contribute to the fast IEDDA kinetics and describe the most recent advances in the synthesis of tetrazine and dienophile coupling partners. Both coupling partners have been incorporated into proteins for tracking and imaging by use of fluorogenic tetrazines that become strongly fluorescent upon reaction. Selected notable examples of such applications are presented. The exceptional fast kinetics of this catalyst-free reaction, even using low concentrations of coupling partners, make it amenable for in vivo radiolabelling using pretargeting methodologies, which are also discussed. Finally, IEDDA reactions have recently found use in bioorthogonal decaging to activate proteins or drugs in gain-of-function strategies. We conclude by showing applications of the IEDDA reaction in the construction of biomaterials that are used for drug delivery and multimodal imaging, among others. The use and utility of the IEDDA reaction is interdisciplinary and promises to revolutionize chemical biology, radiochemistry and materials science.

Abstract
![]()
Bioorthogonal chemistry
can be used for the selective modification
of biomolecules without interfering with any other functionality present
in the cell. The tetrazine ligation is very suitable as a bioorthogonal
reaction because of its selectivity and high reaction rates with several
alkenes and alkynes. Recently, we described vinylboronic acids (VBAs)
as novel hydrophilic bioorthogonal moieties that react efficiently
with dipyridyl-s-tetrazines and used them for protein
modification in cell lysate. It is not clear, however, whether VBAs
are suitable for labeling experiments in living cells because of the
possible coordination with, for example, vicinal carbohydrate diols.
Here, we evaluated VBAs as bioorthogonal reactants for labeling of
proteins in living cells using an irreversible inhibitor of the proteasome
and compared the reactivity to that of an inhibitor containing norbornene,
a widely used reactant for the tetrazine ligation. No large differences
were observed between the VBA and norbornene probes in a two-step
labeling approach with a cell-penetrable fluorescent tetrazine, indicating
that the VBA gives little or no side reactions with diols and can
be used efficiently for protein labeling in living cells.

Abstract

Virus
capsids, i.e., viruses devoid of their genetic material,
are suitable nanocarriers for biomedical applications such as drug
delivery and diagnostic imaging. For this purpose, the reliable encapsulation
of cargo in such a protein nanocage is crucial, which can be accomplished
by the covalent attachment of the compounds of interest to the protein
domains positioned at the interior of the cage. This approach is particularly
valid for the capsid proteins of the cowpea chlorotic mottle virus
(CCMV), which have their N-termini located at the inside of the capsid
structure. Here, we examined several site-selective modification methods
for covalent attachment and encapsulation of cargo at the N-terminus
of the CCMV protein. Initially, we explored approaches to introduce
an N-terminal azide functionality, which would allow the subsequent
bioorthogonal modification with a strained alkyne to attach the desired
cargo. As these methods showed compatibility issues with the CCMV
capsid proteins, a strategy based on 2-pyridinecarboxaldehydes for
site-specific N-terminal protein modification was employed. This method
allowed the successful modification of the proteins, and was applied
for the introduction of a bioorthogonal vinylboronic acid moiety.
In a subsequent reaction, the proteins could be modified further with
a fluorophore using the tetrazine ligation. The application of capsid
assembly conditions on the functionalized proteins led to successful
particle formation, showing the potential of this covalent encapsulation
strategy.

Abstract
Bioorthogonal dissociative reactions boast diverse potential applications in chemical biology and drug delivery. The reaction of benzonorbornadienes with tetrazines to release amines from carbamate leaving groups was recently introduced as a bioorthogonal bond-cleavage reaction. The present study aimed at investigating the scope of leaving groups that are compatible with benzonorbornadienes. Synthesis of several benzonorbornadienes with different releasable groups is reported, and the reaction of these molecules with tetrazine was found to be rapid and afforded high release yields. The tetrazine-induced release of molecules proceeds in a cascade of steps including inverse-electron demand cycloaddition and cycloreversion reactions that form unstable isoindoles/isobenzofuran intermediates and spontaneously eliminate a leaving group of interest. In the case of oxygen-bridged BNBDs at room temperature, we observed the formation of an unproductive byproduct.

Abstract
Bio-orthogonal labelling schemes based on inverse-electron-demand Diels-Alder (IEDDA) cycloaddition have attracted much attention in chemical biology recently. The appealing features of this reaction, such as the fast reaction kinetics, fully bio-orthogonal nature and high selectivity, have helped chemical biologists gain deeper understanding of biochemical processes at the molecular level. Listing the components and discussing the possibilities and limitations of these reagents, we provide a recent snapshot of the field of IEDDA-based biomolecular manipulation with special focus on fluorescent modulation approaches through the use of bio-orthogonalized building blocks. At the end, we discuss challenges that need to be addressed for further developments in order to overcome recent limitations and to enable researchers to answer biomolecular questions in more detail.

Abstract
As potent and selective therapeutic agents, peptides and proteins are an important class of drugs, but they typically have suboptimal pharmacokinetic profiles. One approach to solve this problem is their conjugation with "stealth" polymers. Conventional methods for conjugation of this class of polymers to peptides and proteins are typically carried out by reactions that have poor yield and provide limited control over the site of conjugation and the stoichiometry of the conjugate. To address these limitations, new chemical and biological approaches have been developed that provide new molecular tools in the bioconjugation toolbox to create stealth polymer conjugates of peptides and proteins with exquisite control over their properties. This review article highlights these recent advances in the synthesis of therapeutic peptide- and protein-stealth polymer conjugates.

Abstract
Bioorthogonal reactions are widely used for the chemical modification of biomolecules. The application of vinylboronic acids (VBAs) as non‐strained, synthetically accessible and water‐soluble reaction partners in a bioorthogonal inverse electron‐demand Diels–Alder (iEDDA) reaction with 3,6‐dipyridyl‐s‐tetrazines is described. Depending on the substituents, VBA derivatives give second‐order rate constants up to 27 m−1 s−1 in aqueous environments at room temperature, which is suitable for biological labeling applications. The VBAs are shown to be biocompatible, non‐toxic, and highly stable in aqueous media and cell lysate. Furthermore, VBAs can be used orthogonally to the strain‐promoted alkyne–azide cycloaddition for protein modification, making them attractive complements to the bioorthogonal molecular toolbox.
