Abstract
Post-synthetic modification of nucleic acid structures with clickable functionality is a versatile tool that facilitates many emerging applications, including immune evasion, enhancements in stability, fluorescent labelling, chemical 5'-RNA-capping and the development of functional aptamers. While certain chemoenzymatic approaches for 3'-azido and alkynyl labelling are known, equivalent 5'-strategies are either inefficient, complex, or require harsh chemical conditions. Here, we present a modular and facile technology to consecutively modify DNA and RNA strands at both ends with click-modifiable functional groups. Our approach using γ-modified ATP analogues facilitates T4 PNK-catalysed 5'-modification of oligonucleotides, a process that is compatible with TdT-catalysed 3'-elongation using 3'-azido-2',3'-ddGTP. Finally, we demonstrate that our approach is suitable for both oligo-oligo ligations, as well ssDNA circularization. We anticipate that such approaches will pave the way for the synthesis of highly functionalised oligonucleotides, improving the therapeutic and diagnostic applicability of oligonucleotides such as in the realm of next-generation sequencing.

Abstract
Protein phosphorylation is one of the most basic mechanisms for regulating and controlling protein biological activity and function, and it is also a very important posttranslational modification process. Protein phosphorylation participates in and regulates many life activities such as signal transduction, gene expression, cell cycle, and so on. In this paper, we propose a method for the determination of the protein phosphorylation combining capillary electrophoresis (CE) with ATP analog labeling technique. We synthesized two new ATP analogs (ATP-NB and ATP-TATD-NB) functionalized by norbornene. Using Abl kinase as a model, we established a method for the determination of the kinase activity in solution and lysate by CE with laser-induced fluorescence detection (CE-LIF). This method was used to evaluate the efficiencies of kinase inhibitors. The IC50 values obtained are basically consistent with the reports. By D-A reaction (inverse electron demand Diels-Alder reaction) to label TZ-BODIPY fluorescence, we also realized the phosphorylation fluorescence detection of substrate peptide. Then, we used fluorescence confocal microscopy imaging technology to study the phosphorylation of proteins in vivo by the D-A reaction of ATP-NB and TZ-BODIPY. Our preliminary results documented that the combination of CE-LIF with analog ATP-NB labeling technique is an effective strategy for the determination of the protein phosphorylation and the kinase activity and for screening of kinase inhibitors. The D-A reaction of ATP-NB and TZ-BODIPY also laid the foundation for the subsequent in situ study of protein phosphorylation.

Abstract
γ-Amido-modified 2'-deoxynucleoside triphosphates (dNTPs) and nucleoside triphosphates (NTPs) are becoming increasingly important as biological tools. We herein describe the simple and easy synthesis of γ-amido-dNTPs and -NTPs from commercially available corresponding dNTPs and NTPs in a one-pot reaction using water-soluble carbodiimide and ammonia solution. We examined the effects of synthesized γ-amido-dNTPs on the DNA polymerase reaction. The results obtained showed the incorporation of these derivatives into the DNA primer while maintaining nucleobase selectivity; however, their incorporation efficiency by DNA polymerase was lower than that of dNTP. This is the first study to demonstrate the successful synthesis of four sets of γ-amido-dNTPs and clarify their properties.

Abstract
Cellular oxidative thymines, 5-hydroxymethyluracil (5hmU) and 5-formyluracil (5fU), are found in the genomes of a diverse range of organisms, the distribution of which profoundly influence biological processes and living systems. However, the distribution of cellular oxidative thymines has not been explored because of lacking both specific bioorthogonal labeling and sensitivity methods for single-cell analysis. Herein, we report a bioorthogonal chemical signature enabling amplified visualization of cellular oxidative thymines in single cells. The synthesized ATP-γ-alkyne, an ATP analogue with bioorthogonal tag modified on γ-phosphate can be specifically linked to cellular 5hmU by chemoenzymatic labeling. DNA with 5-alkynephosphomethyluracil were then clicked with azide (N3)-modified 5hmU-primer. Identification of 5fU is based on selective reduction from 5fU to 5hmU, subsequent chemoenzymatic labeling of the newly generated 5hmU, and cross-linking with N3-modified 5fU-primer via click chemistry. Then, all of the 5hmU and 5fU sites are encoded with respective circularized barcodes. These barcodes are simultaneously amplified for multiplexed single-molecule imaging. The above two kinds of barcodes can be simultaneously amplified for differentiated visualization of 5hmU and 5fU in single cells. We find these two kinds of cellular oxidative thymines are spatially organized in a cell-type-dependent style with cell-to-cell heterogeneity. We also investigate their multilevel subcellular information and explore their dynamic changes during cell cycles. Further, using DNA sequencing instead of fluorescence imaging, our proposed bioorthogonal chemical signature holds great potential to offer the sequence information of these oxidative thymines in cells and may provide a reliable chemical biology approach for studying the whole-genome oxidative thymines profiles and insights into their functional role and dynamics in biology.

Abstract
Nucleoside triphosphates (NTPs) are essential biomolecules involved in almost all biological processes, and their study is therefore critical to understanding cellular biology. Here, we describe a chemical synthesis suitable for obtaining both natural and highly modified NTPs, which can, for example, be used as surrogates to probe biological processes. The approach includes the preparation of a reagent that enables the facile introduction and modification of three phosphate units: cyclic pyrophosphoryl P-amidite (c-PyPA), derived from pyrophosphate (PV ) and a reactive phosphoramidite (PIII ). By using non-hydrolyzable analogues of pyrophosphate, the reagent can be readily modified to obtain a family of non-hydrolyzable analogues containing CH2 , CF2 , CCl2 , and NH that are stable in solution for several weeks if stored appropriately. They enable the synthesis of NTPs by reaction with nucleosides to give deoxycyclotriphosphate esters that are then oxidized to cyclotriphosphate (cyclo-TP) esters. The use of different oxidizing agents provides an opportunity for modification at P-α. Furthermore, terminal modifications at P-γ can be introduced by linearization of the cyclo-TP ester with various nucleophiles. © 2020 The Authors.

Abstract
Exploring spatial organization and relationship of diverse biomolecules within cellular nanoenvironments is important to elucidate the fundamental processes of life. However, it remains methodologically challenging. Herein, we report a molecular recognition mechanism cellular macromolecules-tethered DNA walking indexing (Cell-TALKING) to probe the nanoenvironments containing diverse chromatin modifications. As an example, we characterize the nanoenvironments of three DNA modifications around one histone posttranslational modification (PTM). These DNA modifications in fixed cells are labeled with respective DNA barcoding probes, and then the PTM site is tethered with a DNA walking probe. Cell-TALKING can continuously produce cleavage records of any barcoding probes nearby the walking probe. New 3'-OH ends are generated on the cleaved barcoding probes to induce DNA amplification for downstream detections. Combining fluorescence imaging, we identify various combinatorial chromatin modifications and investigate their dynamic changes during cell cycles. We also explore the nanoenvironments in different cancer cell lines and clinical specimens. In principle, using high-throughput sequencing instead of fluorescence imaging may allow the detection of complex cellular nanoenvironments containing tens of biomolecules such as transcription factors.

Abstract
Modified nucleoside triphosphates (NTPs) are invaluable tools to probe bacterial enzymatic mechanisms, develop novel genetic material, and engineer drugs and proteins with new functionalities. Although the impact of nucleobase alterations has predominantly been studied due to their importance for protein recognition, sugar and phosphate modifications have also been investigated. However, NTPs are cell impermeable due to their negatively charged phosphate tail, a major hurdle to achieving live bacterial studies. Herein, we review the recent advances made to investigate and evolve bacteria and their processes with the use of modified NTPs by exploring alterations in one of the three moieties: the nucleobase, the sugar and the phosphate tail. We also present the innovative methods that have been devised to internalize NTPs into bacteria for in vivo applications.

Abstract
Chemo- and site-specific modifications in oligonucleotides have wide applicability as mechanistic probes in chemical biology. However, methods that label specific sites in nucleic acids are scarce, especially for labeling DNA/RNA from biological or enzymatic sources rather than synthetic ones. Here we have employed a classical reaction, reductive amination, to selectively functionalize the N2-amine of guanosine and 2'-deoxyguanosine monophosphate (GMP/dGMP). This method specifically modifies guanine in DNA and RNA oligonucleotides, while leaving the other nucleobases unaffected. Using this approach, we have successfully incorporated a reactive handle chemoselectively into nucleic acids for further functionalization and downstream applications.

Abstract
We describe a new type of nucleotide-derived fluorescent probe designed for monitoring pyrophosphatase activity based on excimer-to-monomer transitions, called ExciTide. The nucleotides were designed with two self-interacting dye moieties and synthesised using copper-catalysed azide-alkyne cycloaddition click chemistry. We applied these probes for enzyme activity monitoring and inhibitor evaluation. Some of the probes permeated into living cells, yielding interesting prospects for future applications.

Abstract
Homogeneous catalysis plays an important and ubiquitous role in the synthesis of simple and complex molecules, including drug compounds, natural products, and agrochemicals. In recent years, the wide-reaching importance of homogeneous catalysis has made it an indispensable tool for the modification of biomolecules, such as carbohydrates (sugars), amino acids, peptides, nucleosides, nucleotides, and steroids. Such a synthetic strategy offers several advantages, which have led to the development of new molecules of biological relevance at a rapid rate relative to the number of available synthetic methods. Given the powerful nature of homogeneous catalysis in effecting these synthetic transformations, this Focus Review has been compiled to highlight these important developments.

Abstract
A conjugate of triphosphorylated 2',3'-dideoxyuridine (ddU) with SiO2 nanoparticles was obtained via the CuAAC click chemistry between a γ-alkynyl ddU triphosphate and azido-modified SiO2 nanoparticles. Assessment of cytotoxicity in human breast adenocarcinoma MCF7 cells demonstrated that ddU triphosphate conjugated to SiO2 nanoparticles exhibited a 50% decrease in cancer cell growth at a concentration of 183 ± 57 µg/mL, which corresponds to 22 ± 7 µM of the parent nucleotide, whereas the parent nucleoside, nucleotide and alkynyl triphosphate precursor do not show any cytotoxicity. The data provide an example of remarkable potential of novel conjugates of SiO2 nanoparticles with phosphorylated nucleoside analogues, even those, which have not been used previously as therapeutics, for application as new anticancer agents.

Abstract
Nucleotides modified at the terminal phosphate position have been proven to be interesting entities to study the activity of a variety of different protein classes. In this chapter, we present various types of modifications that were attached as reporter molecules to the phosphate chain of nucleotides and briefly describe the chemical reactions that are frequently used to synthesize them. Furthermore, we discuss a variety of applications of these molecules. Kinase activity, for instance, was studied by transfer of a phosphate modified with a reporter group to the target proteins. This allows not only studying the activity of kinases, but also identifying their target proteins. Moreover, kinases can also be directly labeled with a reporter at a conserved lysine using acyl-phosphate probes. Another important application for phosphate-modified nucleotides is the study of RNA and DNA polymerases. In this context, single-molecule sequencing is made possible using detection in zero-mode waveguides, nanopores or by a Förster resonance energy transfer (FRET)-based mechanism between the polymerase and a fluorophore-labeled nucleotide. Additionally, fluorogenic nucleotides that utilize an intramolecular interaction between a fluorophore and the nucleobase or an intramolecular FRET effect have been successfully developed to study a variety of different enzymes. Finally, also some novel techniques applying electron paramagnetic resonance (EPR)-based detection of nucleotide cleavage or the detection of the cleavage of fluorophosphates are discussed. Taken together, nucleotides modified at the terminal phosphate position have been applied to study the activity of a large diversity of proteins and are valuable tools to enhance the knowledge of biological systems.

Abstract
Monitoring the activity of ATP-consuming enzymes provides the basis for elucidating their modes of action and regulation. Although a number of ATP analogues have been developed for this, their scope is restricted because of the limited acceptance by respective enzymes. In order to clarify which kind of phosphate-modified ATP analogues are accepted by the α-β-phosphoanhydride-cleaving ubiquitin-activating enzyme 1 (UBA1) and the β-γ-phosphoanhydride-cleaving focal adhesion kinase (FAK), we tested phosphoramidate- and phosphoester-modified ATP analogues. UBA1 and FAK were able to convert phosphoramidate-modified ATP analogues, even with a bulky modification like biotin. In contrast, a phosphoester-modified analogue was poorly accepted. These results demonstrate that minor variations in the design of ATP analogues for monitoring ATP utilization have a significant impact on enzymatic acceptance.

Abstract
7-Methylguanosine (m(7)G) nucleotides labelled with acetylpyrene (AcPy) were synthesized as fluorescent mRNA 5' end (cap) analogues. The unique fluorescent properties of m(7)G-AcPy conjugates, different from G-AcPy, can be applied to studying various mRNA cap-related processes including the evaluation of putative inhibitors of DcpS enzyme-a therapeutic target in neuromuscular diseases.

Abstract
A sterically undemanding azide analogue of dTTP (AHP dUTP) with an alkyl chain and ethynyl attachment to the nucleobase was designed and incorporated into DNA by primer extension, reverse transcription and polymerase chain reaction (PCR). An azide-modified 523 bp PCR amplicon with all 335 thymidines replaced by AHP dU was shown to be a perfect copy of the template from which it was amplified. Replacement of thymidine with AHP dU increases duplex stability, accounting in part for the high incorporation efficiency of the azide-modified triphosphate. Single-stranded azide-labelled DNA was conveniently prepared from PCR products by λ-exonuclease digestion and streptavidin magnetic bead isolation. Efficient fluorescent labelling of single and double-stranded DNA was carried out using dyes functionalized with bicyclo[6.1.0]non-4-yne (BCN) via the strain-promoted alkyne-azide cycloaddition (SPAAC) reaction. This revealed that the degree of labelling must be carefully controlled to achieve optimum fluorescence and avoid fluorescence quenching. Dual-coloured probes were obtained in a single tube fluorescent labelling reaction; and varying the ratios of the two dyes provides a simple method to prepare DNA probes with unique fluorescent signatures. AHP dUTP is a versatile clickable nucleotide with potentially wide applications in biology and nanotechnology including single molecule studies and synthesis of modified aptamer libraries via SELEX.

Abstract
Phosphoanhydrides (P-anhydrides) are ubiquitously occurring modifications in nature. Nucleotides and their conjugates, for example, are among the most important building blocks and signaling molecules in cell biology. To study and manipulate their biological functions, a diverse range of analogues have been developed. Phosphate-modified analogues have been successfully applied to study proteins that depend on these abundant cellular building blocks, but very often both the preparation and purification of these molecules are challenging. This study discloses a general access to P-anhydrides, including different nucleotide probes, that greatly facilitates their preparation and isolation. The convenient and scalable synthesis of, for example, (18) O labeled nucleoside triphosphates holds promise for future applications in phosphoproteomics.

Abstract
The synthesis and reactivity of a novel class of clickable nucleotide analogues containing a C-phosphonate subunit that has an alkyne group at the terminal position of the oligophosphate chain are reported. The C-phosphonate subunits were prepared by simple one- or two-step procedures using commercially available reagents. Nucleotides were prepared by MgCl2-catalyzed coupling reactions and then subjected to CuAAC reactions with various azide compounds to afford 5'-γ-labeled nucleoside triphosphates in excellent yields.

Abstract
A series of π-extended distyryl-substituted boron dipyrromethene (BODIPY) derivatives with intense far-red/near-infrared (NIR) fluorescence was synthesized and characterized, with a view to enhance the dye's performance for fluorescence labeling. An enhanced brightness was achieved by the introduction of two methyl substituents in the meso positions on the phenyl group of the BODIPY molecule; these substituents resulted in increased structural rigidity. Solid-state fluorescence was observed for one of the distyryl-substituted BODIPY derivatives. The introduction of a terminal bromo substituent allows for the subsequent immobilization of the BODIPY fluorophore on the surface of carbon nano-onions (CNOs), which leads to potential imaging agents for biological and biomedical applications. The far-red/NIR-fluorescent CNO nanoparticles were characterized by absorption, fluorescence, and Raman spectroscopies, as well as by thermogravimetric analysis, dynamic light scattering, high-resolution transmission electron microscopy, and confocal microscopy.

Abstract
Esters and anhydrides of phosphoric acid are essential in biology. It is very difficult to identify processes in life that do not involve these modifications and their transformation at some point. Consequently, phosphorylation chemistry is an essential methodology with significant impact on the biological sciences. This perspective gives an overview of some very recent achievements in synthetic phosphorylation chemistry and aims at identifying challenges that lie ahead.
