Abstract
Cancer continues to be leading cause of morbidity and mortality despite decades of research and advancement in chemotherapy. Most tumors can be reduced via standard oncology treatments, such as chemotherapy, radiotherapy, and surgical resection, and they frequently recur. Significant progress has been made since targeted cancer therapy inception in creation of medications that exhibit improved tumor-selective action. Particularly in preclinical and clinical investigations, fusion proteins have shown strong activity and improved treatment outcomes for a number of human cancers. Synergistically combining many proteins into one complex allows the creation of synthetic fusion proteins with enhanced characteristics or new capabilities. Signal transduction pathways are important for onset, development, and spread of cancer. As result, signaling molecules are desirable targets for cancer therapies, and significant effort has been made into developing fusion proteins that would act as inhibitors of these pathways. A wide range of biotechnological and medicinal applications are made possible by fusion of protein domains that improves bioactivities or creates new functional combinations. Such proteins may function as immune effectors cell recruiters to tumors or as decoy receptors for various ligands. In this review article, we have outlined the standard methods for creating fusion proteins and covered the applications of fusion proteins in treatment of cancer. This article also highlights the role of fusion proteins in targeting the signaling pathways involved in cancer for effective treatment.

Abstract
Fc fusions are a growing class of drugs comprising an antibody Fc domain covalently linked to a protein or peptide and can pose manufacturing challenges. In this study we evaluated three synthetic approaches to generate Fc fusions, using Fc-insulin as a model drug candidate. Engineered human IgG1 was digested with HRV3C to produce an Fc fragment with a C-terminal sortase tag (Fc-LPETGGH6). The synthesis of Fc-insulin2 from Fc-LPETGGH6 was evaluated with direct sortase-mediated ligation (SML) and two chemoenzymatic strategies. Direct SML was performed with triglycine-insulin, and chemoenzymatic strategies used to SML fuse either triglycine-azide or triglycine-DBCO prior to linking insulin with copper-catalyzed or strain-promoted azidealkyne cycloaddition. Reaction conditions were optimized by evaluating reagent concentrations, relative equivalents, temperature, and time. Direct SML provided the most effective reaction yields, converting 60-70% of Fc-LPETGGH6 to Fc-insulin2, whereas our optimized chemoenzymatic synthesis converted 30-40% of Fc-LPETGGH6 to Fc-insulin2. Here we show that SML is a practical and efficient method to synthesize Fc fusions and provide an optimized pathway for fusion drug synthesis.

Abstract
Although a plethora of chemistries have been developed to selectively decorate protein molecules, novel strategies continue to be reported with the final aim of improving selectivity and mildness of the reaction conditions, preserve protein integrity, and fulfill all the increasing requirements of the modern applications of protein conjugates. The targeting of the protein N-terminal alpha-amine group appears a convenient solution to the issue, emerging as a useful and unique reactive site universally present in each protein molecule. Herein, we provide an updated overview of the methodologies developed until today to afford the selective modification of proteins through the targeting of the N-terminal alpha-amine. Chemical and enzymatic strategies enabling the selective labeling of the protein N-terminal alpha-amine group are described.

Abstract
Multimeric antigen display and high overall valency are increasingly regarded as strategic goals for potent and broadly efficacious synthetic vaccines with potential market prospects. Herein, a modular and versatile approach to multifunctional peptide-based vaccine platforms at multimilligram scale in reasonable yields is reported. Preparation of chemoselectively modified peptide building blocks of medium-to-large size, conjugation of these subunits, and final assembly were achieved by a combination of Michael-type thiol-ene addition and copper(I)-mediated alkyne-azide cycloaddition. The size and structural complexity of the building blocks required exploration of a further level of orthogonality, namely furan/maleimide Diels-Alder chemistry. After process optimization, a finely tuned, stepwise click approach has emerged as a workable, on-demand strategy to create macromolecular therapeutic vaccine assemblies.

Sortase-click strategy for defined protein conjugation on a heptavalent cyclodextrin scaffold. PLoS One 2019; 14:e0217369.

Abstract
Multivalent proteins or protein dendrimers are useful for clinical and biotechnological applications. However, assembly of chemically defined protein dendrimers is a challenging endeavor. In the past, majority of protein dendrimers have been developed on branched lysine scaffolds and are usually limited to a valency of two to four. The naturally occurring cyclodextrin (CD) scaffold composed of 6–8 glucose units offers the possibility of expanding the valency. Here we have adapted a chemoenzymatic-click strategy for displaying heptavalent peptides and large proteins on the β-cyclodextrin (β-CD) scaffold. We demonstrate that recombinant proteins (engineered with a LPXTG pentapeptide motif at the carboxy terminus), labeled with an alkyne moiety by sortase-mediated ligation, can be easily clicked on to the azide-derivatized β-cyclodextrin through the Huisgen cycloaddition reaction yielding a well-defined heptavalent display of proteins.

Abstract
The emergence of bioorthogonal reactions has greatly broadened the scope of biomolecule labeling and detecting. Of all the bioorthogonal reactions that have been developed, the copper-catalyzed azide-alkyne cycloaddition (CuAAC) is the most widely applied one, mainly because of its relatively fast kinetics and high efficiency. However, the introduction of copper species to in vivo systems raises the issue of potential toxicity. In order to reduce the copper-induced toxicity and further improve the reaction kinetics and efficiency, different strategies have been adopted, including the development of diverse copper chelating ligands to assist the catalytic cycle and the development of chelating azides as reagents. Up to now, the optimization of CuAAC has facilitated its applications in labeling and identifying either specific biomolecule species or on the omics level. Herein, we mainly discuss the efforts in the development of CuAAC to better fit the bioorthogonal reaction criteria and its bioorthogonal applications both in vivo and in vitro.

Abstract
Biomacromolecules offer complex and precise functions embedded in their monomer sequence such as enzymatic activity or specific interactions towards other molecules. Their informational content and capability to organize in higher ordered structures is superior to those of synthetic molecules. In comparison, synthetic polymers are easy to access even at large production scales and they are chemically more diverse. Solubilization, shielding against enzymatic degradation to more advanced functions like switchability or protein mimicry, etc., are accessible through the world of polymer chemistry. Bio-inspired hybrid materials consisting of peptides or proteins and synthetic polymers thereby combine the properties of both molecules to give rise to a new class of materials with unique characteristics and performance. To obtain well-defined bioconjugate materials, high yielding and site-specific as well as biorthogonal ligation techniques are mandatory. Since the first attempts of protein PEGylation in the 1970s and the concept of “click” chemistry arising in 2001, continuous progress in the field of peptide– and protein–polymer conjugate preparation has been gained. Herein, we provide an overview on ligation techniques to prepare functional bioconjugates published in the last decade, also referred to as “post-click” methods. Furthermore, chemoenzymatic approaches and biotransformation reactions used in peptide or protein modification, as well as highly site-specific and efficient reactions originated in synthetic macromolecular chemistry, which could potentially be adapted for bioconjugation, are presented. Finally, future perspectives for the preparation and application of bioconjugates at the interface between biology and synthetic materials are given.

Abstract
The properties of biosensors, biomedical implants, and other materials based on immobilized proteins greatly depend on the method employed to couple the protein molecules to their solid support. Covalent, site-specific immobilization strategies are robust and can provide the level of control that is desired in this kind of application. Recent advances include the use of enzymes, such as sortase A, to couple proteins in a site-specific manner to materials such as microbeads, glass, and hydrogels. Also, self-labeling tags such as the SNAP-tag can be employed. Last but not least, chemical approaches based on bioorthogonal reactions, like the azide-alkyne cycloaddition, have proven to be powerful tools. The lack of comparative studies and quantitative analysis of these immobilization methods hampers the selection process of the optimal strategy for a given application. However, besides immobilization efficiency, the freedom in selecting the site of conjugation and the size of the conjugation tag and the researcher's expertise regarding molecular biology and/or chemical techniques will be determining factors in this regard.

Abstract
INTRODUCTION In recent years, a variety of new synthetic methodologies and concepts have been proposed in the search for new pharmaceutical lead structures and optimization. Notably, the Cu(I)-catalyzed azide-alkyne cycloaddition (CuAAC) click chemistry approach has drawn great attention and has become a powerful tool for the generation of privileged medicinal skeletons in the discovery of anti-HIV agents. This is due to the high degree of reliability, complete specificity (chemoselectivity and regioselectivity), mild conditions, and the biocompatibility of the reactants. AREAS COVERED Herein, the authors describe the progress thus far on the discovery of novel anti-HIV agents via the CuAAC click chemistry-based approach. EXPERT OPINION CuAAC click chemistry is a proven protocol for synthesizing triazole products which could serve as basic pharmacophores, act as replacements of traditional scaffold or substituent modification, be a linker of dual-target or dual-site inhibitors and more for the discovery of novel anti-HIV agents. What's more, it also provides convenience and feasibility for dynamic combinatorial chemistry and in situ screening. It is envisioned that click chemistry will draw more attention and make more contributions in anti-HIV drug discovery in the future.

Abstract
Synthetic fusion proteins can be designed to achieve improved properties or new functionality by synergistically incorporating multiple proteins into one complex. The fusion of two or more protein domains enhances bioactivities or generates novel functional combinations with a wide range of biotechnological and (bio)pharmaceutical applications. In this review, initially, we summarize the commonly used approaches for constructing fusion proteins. For each approach, the design strategy and desired properties are elaborated with examples of recent studies in the areas of biocatalysts, protein switches and bio-therapeutics. Subsequently, the progress in structural prediction of fusion proteins is presented, which can potentially facilitate the structure-based systematic design of fusion proteins toward identifying the best combinations of fusion partners. Finally, the current challenges and future directions in this field are discussed.

Abstract
Site-specific incorporation of bioorthogonal unnatural amino acids into proteins provides a useful tool for the installation of specific functionalities that will allow for the labeling of proteins with virtually any probe. We demonstrate the genetic encoding of a set of alkene lysines using the orthogonal PylRS/PylTCUA pair in Escherichia coli. The installed double bond functionality was then applied in a photoinitiated thiol-ene reaction of the protein with a fluorescent thiol-bearing probe, as well as a cysteine residue of a second protein, showing the applicability of this approach in the formation of heterogeneous non-linear fused proteins.

Abstract
Engineering artificial protein hydrogels for medical applications requires precise control over their mechanical properties, including stiffness, toughness, extensibility and stability in the physiological environment. Here we demonstrate topological entanglement as an effective strategy to robustly increase the mechanical tunability of a transient hydrogel network based on coiled-coil interactions. Chain extension and entanglement are achieved by coupling the cysteine residues near the N- and C- termini, and the resulting chain distribution is found to agree with the Jacobson-Stockmayer theory. By exploiting the reversible nature of the disulfide bonds, the entanglement effect can be switched on and off by redox stimuli. With the presence of entanglements, hydrogels exhibit a 7.2-fold enhanced creep resistance and a suppressed erosion rate by a factor of 5.8, making the gels more mechanically stable in a physiologically relevant open system. While hardly affecting material stiffness (only resulting in a 1.5-fold increase in the plateau modulus), the entanglements remarkably lead to hydrogels with a toughness of 65,000 J m-3 and extensibility to approximately 3,000% engineering strain, which enables the preparation of tough yet soft tissue simulants. This improvement in mechanical properties resembles that from double-network hydrogels, but is achieved with the use of a single associating network and topological entanglement. Therefore, redox-triggered chain entanglement offers an effective approach for constructing mechanically enhanced and responsive injectable hydrogels.

Abstract
The HIV-1 envelope gp120/gp41 glycoprotein complex plays a critical role in virus-host cell membrane fusion and has been a focus for the development of HIV fusion inhibitors. In this Letter, we present the synthesis of dimers of HIV fusion inhibitor peptides C37H6 and CP32M, which target the trimeric gp41 in the pre-hairpin intermediate state to inhibit membrane fusion. Reactive peptide modules were synthesized using native chemical ligation and then assembled into dimers with varying linker lengths using Cu(I)-catalyzed azide-alkyne cycloaddition (CuAAC) 'click' chemistry. Cell-cell fusion inhibition assays demonstrated that dimers with a (PEG)7 linker showed enhanced antiviral potency over the corresponding monomers. Moreover, the bio-orthogonal nature of the CuAAC 'click' reaction provides a practical way to assemble heterodimers of HIV fusion inhibitors. Heterodimers consisting of the T20-sensitive strain inhibitor C37H6 and the T20-resistant strain inhibitor CP32M were produced that may have broader spectrum activities against both T20-sensitive and T20-resistant strains.

Abstract
Annexin V (1) specifically binds to phosphatidylserine on apoptotic and necrotic cells as well as certain cancer cells, making it an attractive vehicle for the delivery of therapeutically-relevant conjugates to such sites. The wild-type protein possesses a single thiol at Cys316, which is difficultly accessible to site-specific labeling by simple maleimides. By contrast, 1,4-benzoquinone site-specifically labels annexin V in minutes. The resulting conjugate (5) serves as an intermediate for crosslinking annexin molecules, which can be accomplished within hours either directly for linking annexin V-128 (19), or via an extended sequence involving the crosslinking of two units of (5) by the symmetrical α,ω-dithiol (20). Besides its ability to mediate protein dimer formation while retaining annexin V's ability to bind phosphatidylserine, (5) possesses classic 1,4-benzoquinone reactivity. Various nucleophiles and Diels-Alder dienes form adducts with (5) in reactions that may have general utility for the synthesis of novel biologically active entities. The present work presents the first example of thiol-specific crosslinking of proteins by 1,4-quinone-based methodology designed to exploit the reactivity of this versatile chemical entity.

Abstract
Copper(I) is able to catalyze Huisgen 1,3-dipolar cycloaddition in a "click" fashion. This copper-catalyzed azide-alkyne cycloaddition (CuAAC) reaction presents excellent chemoselectivity and occurs over a wide-range of reaction conditions. It shows tolerance to variation in both pH and solvent polarity, thereby facilitating the ligation of peptides and proteins to produce peptidomimetics and synthetic proteins. In addition, the only product formed is a 1,4-disubstituted-1,2,3-triazole moiety, in many aspects resembling the natural peptide bond, including hydrogen-bonding capability, planarity, distance between the 1 and 4 substituents, and conformational restriction of the peptide backbone; thus the triazole-backbone-modified peptide, in which a triazole replaces the amide bond, may be anticipated to present a secondary structure similar to that of its natural counterpart. This Focus Review describes the scope and applications of copper(I)-catalyzed alkyne–azide cycloaddition in synthetic peptide/protein chemistry.

Abstract
Multivalent single chain variable fragments (scFv) show increased affinity to tumor-associated antigens compared to monovalent scFv and intact monoclonal antibodies (mAb). Multivalent constructs can be derived from self-associating or covalent scFv with covalent constructs offering improved in vivo and in vitro stability. Covalent attachment of scFv can be achieved using genetically engineered expression vectors that afford scFv with site specific cysteine functionality. Expression vectors for di-scFv-C wherein the cysteine is located in the center of two scFv have also been developed for attaching chemically reactive linkers. In the example illustrated here, the di-scFv-C is derived from a mAb directed against the MUC1 epitope, which is presented on cancer cells. To achieve multivalency, a chemical crosslinking strategy utilizing various azide and multi-alkyne functionalized polyethylene glycol (PEG) linkers was implemented. Conjugation was achieved by attachment of these linkers to the scFv thiol functionality. Chemoselective ligation was employed to covalently link different protein conjugates via copper(I) catalyzed azide alkyne 1,3-dipolar cycloaddition reaction (CuAAC) chemistry. Ligations were achieved in >70% yield using a specific set of linkers as determined by SDS-PAGE and densitometry. ELISA showed increased tumor binding of a tetravalent scFv providing a versatile chemical crosslinking strategy for construction of multivalent and bi-specific immunoconjugates that retain biological activity and have potential application in pre-targeted radioimmunotherapy and imaging.

Abstract
Methods for synthetically manipulating protein structure enable greater flexibility in the study of protein function. Previous characterization of the Escherichia coli aminoacyl tRNA transferase (AaT) has shown that it can modify the N-terminus of a protein with an amino acid from a tRNA or a synthetic oligonucleotide donor. Here, we demonstrate that AaT can efficiently use a minimal adenosine substrate, which can be synthesized in one to two steps from readily available starting materials. We have characterized the enzymatic activity of AaT with aminoacyl adenosyl donors and found that reaction products do not inhibit AaT. The use of adenosyl donors removes the substrate limitations imposed by the use of synthetases for tRNA charging and avoids the complex synthesis of an oligonucleotide donor. Thus, our AaT donors increase the potential substrate scope and reaction scale for N-terminal protein modification under conditions that maintain folding.

Abstract
Site-specific modification of glycoproteins has wide application in both biochemical and biophysical studies. This method describes the conjugation of synthetic molecules to the N-terminus of a glycoprotein fragment, viz., human immunoglobulin G subclass 1 fragment crystallizable (IgG1 Fc), by native chemical ligation. The glycosylated IgG1 Fc is expressed in a glycosylation-deficient yeast strain. The N-terminal cysteine is generated by the endogenous yeast protease Kex2 in the yeast secretory pathway. The N-terminal cysteine is then conjugated with a biotin thioester to produce a biotinylated, glycosylated IgG1 Fc using native chemical ligation.

Abstract
Dimerization can be utilized to double the molecular weight of proteins and peptides and potentially increase their avidity of binding to target receptors. These dimerization effects may be utilized to increase in vivo half-lives in a manner similar to PEGylation and may also improve biological activity. In this paper, we report a new strategy for the synthesis of N-terminally linked protein and peptide homodimers utilizing native chemical ligation to conjugate a short dithioester linker to the N-terminal cysteines of protein and peptide monomers to form dimers in a single step. This strategy is general and has been applied to the production of dimers from three recombinantly expressed polypeptides, the IgG binding domain Protein G, an HIV entry inhibitor peptide C37H6, and human interleukin-1 receptor antagonist (IL-1ra). The biological activities of the C37H6 and IL-1ra dimers produced by these methods were retained or even slightly increased when compared to their corresponding monomers.
