Abstract
Disulfide rebridging methods are emerging recently as new ways to specifically modify antibody-based entities and produce future conjugates. Briefly, the solvent-accessible disulfide bonds of antibodies or antigen-binding fragments (Fab) thereof are reduced under controlled conditions and further covalently attached with a rebridging agent allowing the incorporation of one payload per disulfide bond. There are many examples of successful rebridging cases providing homogeneous conjugates due to the use of symmetrical reagents, such as dibromomaleimides. However, partial rebridging due to the use of unsymmetrical ones, containing functional groups with different reactivity, usually leads to the development of heterogeneous species that cannot be identified by a simple sodium dodecyl sulfate-polyacrylamide gel eletrophoresis (SDS-PAGE) due to its lack of sensitivity, resolution and low mass accuracy. Mass spectrometry coupled to liquid chromatography (LC-MS) approaches have already been demonstrated as highly promising alternatives for the characterization of newly developed antibody-drug-conjugate (ADC) and monoclonal antibody (mAb)-based formats. We report here the in-depth characterization of covalently rebridged antibodies and Fab fragments in-development, using size-exclusion chromatography hyphenated to mass spectrometry in denaturing conditions (denaturing SEC-MS, dSEC-MS). DSEC-MS was used to monitor closely the rebridging reaction of a conjugated trastuzumab, in addition to conjugated Fab fragments, which allowed an unambiguous identification of the covalently rebridged products along with the unbound species. This all-in-one approach allowed a straightforward analysis of the studied samples with precise mass measurement; critical quality attributes (CQAs) assessment along with rebridging efficiency determination.

Abstract
Double-stranded RNAs (dsRNA)-based strategies appeared as promising therapies to induce an inflammation in the tumor microenvironment. However, currently described systems generally lack active targeting of tissues, and their clinical translation is thus limited to intratumoral injection. Herein, we developed an antibody-siRNA-5'triphosphate conjugate with multiple modes of action, combining cell surface EphA2-specific internalization, leading to a simultaneous gene silencing and activation of the receptor retinoic acid-inducible gene I (RIG-I). Recognition of cytosolic siRNA-5'triphosphate by RIG-I triggers the expression of interferons and pro-inflammatory cytokines, inducing an inflammation of the tumor environment and activating neighboring immune cells. In addition, these RIG-I-specific effects synergized with siRNA-mediated PLK1 silencing to promote cancer cell death by apoptosis. Altogether, such immune-stimulating antibody-RNA conjugate opens a novel modality to overcome some limitations encountered by dsRNA molecules currently in clinical trials.

Abstract
The chemical bioconjugation of proteins has seen tremendous applications in the past decades, with the booming of antibody-drug conjugates and their use in oncology. While genetic engineering has permitted to produce bespoke proteins featuring key (un-)natural amino acid residues poised for site-selective modifications, the conjugation of native proteins is riddled with selectivity issues. Chemoselective strategies are plentiful and enable the precise modification of virtually any residue with a reactive side-chain; site-selective methods are less common and usually most effective on small and medium-sized proteins. In this context, we studied the application of the Ugi multicomponent reaction for the site-selective conjugation of amine and carboxylate groups on proteins, and antibodies in particular. Through an in-depth mechanistic methodology work supported by peptide mapping studies, we managed to develop a set of conditions allowing the highly selective modification of antibodies bearing N-terminal glutamate and aspartate residues. We demonstrated that this strategy did not alter their affinity toward their target antigen and produced an antibody-drug conjugate with subnanomolar potency. Excitingly, we showed that the high site selectivity of our strategy was maintained on other protein formats, especially on anticalins, for which directed mutagenesis helped to highlight the key importance of a single lysine residue.

Abstract
Peptide and protein bioconjugation sees ever-growing applications in the pharmaceutical sector. Novel strategies and reagents that can address the chemo- and regioselectivity issues inherent to these biomolecules, while delivering stable and functionalizable conjugates, are therefore needed. Herein, we introduce the crosslinking ethynylbenziodazolone (EBZ) reagent JW-AM-005 for the conjugation of peptides and proteins through the selective linkage of cysteine residues. This easily accessed compound gives access to peptide dimers or stapled peptides under mild and tuneable conditions. Applied to the antibody fragment of antigen binding (Fab) species, JW-AM-005 delivered rebridged proteins in a one-pot three-reaction process with high regioselectivity, outperforming the standard reagents commonly used for this transformation.

Abstract
Protein conjugates have found applications in a wide variety of fields, ranging from therapeutics to imaging and detection. However, robust control over the parameters of the conjugation process (such as sites and degree of conjugation) remains challenging. Previously, our group introduced Equimolar NAtive Chemical Tagging (ENACT), a method which allows for the monofunctionalization of proteins by combining an iterative low-conversion bioconjugation, an automated process, and a bioorthogonal trans-tagging reaction. However, while the automated ENACT was dimensioned to achieve monoconjugation at the mg scale, in early stage research, because of the rarity and cost of the starting materials, it is often necessary to prepare conjugates at the lower, μg, scale. Here, we introduce modified ENACT protocols, as well as a new ENACT conjugation reagent, which allow for the monofunctionalization of proteins on the micrograms scale, using minimal quantities of payload.

Abstract
Droplet-based microfluidics is leading the development of miniaturized, rapid, and sensitive version of enzyme-linked immunosorbent assays (ELISAs), a central method for protein detection. These assays involve the use of a functionalized surface able to selectively capture the desired analyte. Using the droplet's oil water interface as a capture surface requires designing custom-perfluorinated fluorosurfactants bearing azide-containing polar groups, which spontaneously react when forming the droplet with strain-alkyne-functionalized antibodies solubilized in the aqueous phase. In this article, we present our research on the influence of the structure of surfactant's hydrophilic heads on the efficiency of SPAAC functionalization and on the effect of this antibody grafting process on droplet stability. We have shown that while short linkers lead to high grafting efficiency, long linkers lead to high stability, and that an intermediate size is required to balance both parameters. In the described family of surfactants, the optimal structure proved to be a PEG4 linker connecting a polar di-azide head and a per-fluoropolyether tail (Krytox). We also found that grafting an increasing amount of antibody, thus increasing interface coverage, increases droplet stability. It thus appears that such a bi-partite system with a reactive fluoro-surfactant in the oil phase and reactive antibody counterpart in the aqueous phase gives access in situ to novel surfactant construct providing unexplored interface structures and droplet functionality.

Abstract
Despite their clinical success, Antibody-Drug Conjugates (ADCs) are still limited to the delivery of a handful of cytotoxic small-molecule payloads. Adaptation of this successful format to the delivery of alternative types of cytotoxic payloads is of high interest in the search for novel anticancer treatments. Herein, we considered that the inherent toxicity of cationic nanoparticles (cNP), which limits their use as oligonucleotide delivery systems, could be turned into an opportunity to access a new family of toxic payloads. We complexed anti-HER2 antibody-oligonucleotide conjugates (AOC) with cytotoxic cationic polydiacetylenic micelles to obtain Antibody-Toxic-Nanoparticles Conjugates (ATNPs) and studied their physicochemical properties, as well as their bioactivity in both in vitro and in vivo HER2 models. After optimising their AOC/cNP ratio, the small (73 nm) HER2-targeting ATNPs were found to selectively kill antigen-positive SKBR-2 cells over antigen-negative MDA-MB-231 cells in serum-containing medium. Further in vivo anti-cancer activity was demonstrated in an SKBR-3 tumour xenograft model in BALB/c mice in which stable 60% tumour regression could be observed just after two injections of 45 pmol of ATNP. These results open interesting prospects in the use of such cationic nanoparticles as payloads for ADC-like strategies.

Abstract
Enzyme-linked immunosorbent assay (ELISA) is a central analytic method in biological science for the detection of proteins. Introduction of droplet-based microfluidics allowed the development of miniaturized, less-consuming, and more sensitive ELISA assays by coencapsulating the biological sample and antibody-functionalized particles. We report herein an alternative in-droplet immunoassay format, which avoids the use of particles. It exploits the oil/aqueous-phase interface as a protein capture and detection surface. This is achieved using tailored perfluorinated surfactants bearing azide-functionalized PEG-based polar headgroups, which spontaneously react when meeting at the droplet formation site, with strained alkyne-functionalized antibodies solubilized in the water phase. The resulting antibody-functionalized inner surface can then be used to capture a target protein. This surface capture process leads to concomitant relocation at the surface of a labeled detection antibody and in turn to a drastic change in the shape of the fluorescence signal from a convex shape (not captured) to a characteristic concave shape (captured). This novel droplet surface immunoassay by fluorescence relocation (D-SIRe) proved to be fast and sensitive at 2.3 attomoles of analyte per droplet. It was further demonstrated to allow detection of cytosolic proteins at the single bacteria level.

Abstract
The bioconjugation of proteins-that is, the creation of a covalent link between a protein and any other molecule-has been studied for decades, partly because of the numerous applications of protein conjugates, but also due to the technical challenge it represents. Indeed, proteins possess inner physico-chemical properties-they are sensitive and polynucleophilic macromolecules-that make them complex substrates in conjugation reactions. This complexity arises from the mild conditions imposed by their sensitivity but also from selectivity issues, viz the precise control of the conjugation site on the protein. After decades of research, strategies and reagents have been developed to address two aspects of this selectivity: chemoselectivity-harnessing the reacting chemical functionality-and site-selectivity-controlling the reacting amino acid residue-most notably thanks to the participation of synthetic chemistry in this effort. This review offers an overview of these chemical bioconjugation strategies, insisting on those employing native proteins as substrates, and shows that the field is active and exciting, especially for synthetic chemists seeking new challenges.

Abstract
Abstract
Simultaneous access to several targets has become the subject of intense studies in immuno-oncology. In order to benefit from the synergies provided by the activation of different signaling pathways in immunology and the knockdown of proteins involved in cancer cell survival, we established a bispecific approach. The activation of the innate immune response by delivering agonists of pattern-recognition receptors (PRR) such as RIG-I (retinoic acid-inducible I) represents a promising strategy. RIG-I detects short double-stranded RNA molecules ended by a 5'-di/triphosphate moiety (5'ppp-dsRNA). RIG-I activation promotes type I IFN secretion and cancer-cell selective apoptosis. To obtain a bifunctional molecule, the 5'ppp-dsRNA sequence was designed to silence PLK1 (polo-like kinase 1). Suppressing PLK1 expression with small interfering RNAs (siRNA) leads to cell cycle arrest and retards cancer cell growth. This concept of bifunctional RNAs has been validated by using non-targeted systems.1
To enhance this synergy, we conjugated this 5'ppp-siPLK1 to an antibody for a specific delivery to cancerous cells that overexpress erythropoietin-producing hepatocellular receptor A2 (EphA2) at their surface. Upon binding to EphA2 receptor, the antibody is well internalized, thus making it a good vehicle to deliver the bispecific 5'ppp-siPLK1. After EphA2-positive cells treatment, we observed RIG-I specific activation as well as PLK1 depletion. Both effects were correlated with cellular apoptosis and the mode of action was further confirmed with mechanistic and kinetic studies. Finally, while non-modified unconjugated siRNA has a very short half-life in plasma, we observed an increase in stability for the antibody-5'ppp-siPLK1 conjugates. These data suggest that anti-EphA2 receptor antibody could be used to deliver a bispecific RNA molecule.

Abstract
Strain-promoted azide-alkyne cycloaddition (SPAAC) is an important member of the bioorthogonal reaction family. Over the past decade, much work has been dedicated to the generation of new strained alkynes with improved reactivity. While kinetics studies of SPAAC are often conducted in organic solvents, buffered solutions or mixtures, these media do not reflect the complexity of in vivo systems. In this work, we show that performing SPAAC in human plasma leads to intriguing kinetics and selectivity effects. In particular, we observed that reactions in plasma could be accelerated up to 70-fold compared to those in methanol, and that selective couplings between a pair of reagents could be possible in competition experiments. These findings highlight the value of evaluating bioorthogonal reactions in such a complex medium, especially when in vivo applications are planned, as unsuspected behaviour can be observed, disrupting the usual rules governing the reactivity in simple solvent systems.

Abstract
Antibody-Oligonucleotide Conjugates (AOCs) represent an emerging class of functionalized antibodies that have already been used in a wide variety of applications. While the impact of dye and drug conjugation on antibodies' ability to bind their target has been extensively studied, little is known about the effect caused by the conjugation of hydrophilic and charged payloads such as oligonucleotides on the functions of an antibody. Previous observations of non-specific interactions of nucleic acids with untargeted cells prompted us to further investigate their impact on AOC binding abilities and cell selectivity. We synthesized a series of single- and double-stranded AOCs, as well as a human serum albumin-oligonucleotide conjugate, and studied their interactions with both targeted and non-targeted living cells using a time-resolved analysis of ligand binding assay. Our results indicate that conjugation of single strand oligonucleotides to proteins induce consistent non-specific interactions with cell surfaces while double strand oligonucleotides have little or no effect, depending on the preparation method.

Abstract
Bicyclo[6.1.0]non-4-yn-9-ylmethanol (BCN alcohol) is the most prominent strained-alkyne scaffold in chemical biology. Described herein is the synthesis of an oxidized analogue – BCN acid – whose facile functionalization via amide bond formation yields more stable derivatives than the classically encountered carbamates. We report a novel strained alkyne, coined BCN acid. This compound participates efficiently in diverse bioorthogonal reactions and allows the facile production of amide probes, which showed superior in vitro stability compared to carbamate analogues.![]()

Abstract
A new alkaloid, manniindole 1, together with four known compounds: aristolactam AII 2, aristolactam BII 3, piperolactam D 4 and polycarpol 5 were isolated from the crude extract EtOH-H2O (8:2) of the roots of Anonidium mannii by chromatographic separation. The structure elucidation was performed on the basis of a spectroscopic analysis (IR, HRESI MS, 1D and 2D NMR) as well as a comparison of their spectral data with those reported in the literature. For the first time, the crude extract and those isolated compounds were evaluated for their anti-schistosomal activity against Schistosoma mansoni and for cytotoxicity activity against Huh7 and A549 cells. Furthermore, they were also tested in vitro on the recent characterized Schistosoma mansoni NAD+ catabolizing enzyme (SmNACE) for their impact on this enzyme which is localized on the outer surface of the adult parasite. Compound 2 displayed quite good worm killing capability, while 4 showed significant inhibition of SmNACE.

Abstract
This review will discuss recent development in the bioconjugation of lysine residues on antibodies. As several chemoselective reagents have already been developed for modifying amine groups, recent strategies now tend to aim at being site-specific. Four general methods have been listed: kinetically controlled, template-directed or enzymatic strategies as well as the use of chemically programmed antibodies.

Abstract
4-Azidophenyl glyoxal enables arginine-selective functionalisation of native antibodies. Being orthogonal to classical lysine conjugation, this method allowed straightforward generation of dual-payload antibody.

Abstract
Full details of the total synthesis of the Schisandraceae nortriterpenoid natural product rubriflordilactone A are reported. Palladium- and cobalt-catalyzed polycyclizations were employed as key strategies to construct the central pentasubstituted arene from bromoendiyne and triyne precursors. This required the independent assembly of two AB ring aldehydes for combination with a common diyne component. A number of model systems were explored to investigate these two methodologies, and also to establish routes for the installation of the challenging benzopyran and butenolide rings.

Abstract
Two enantioselective total syntheses of the nortriterpenoid natural product rubriflordilactone A are described, which use palladium- or cobalt-catalyzed cyclizations to form the CDE rings, and converge on a late-stage synthetic intermediate. These key processes are set up through the convergent coupling of a common diyne component with appropriate AB-ring aldehydes, a strategy that sets the stage for the synthetic exploration of other members of this family of natural products.
