Angew Chem Int Ed Engl 2024; 63:e202403044. [PMID: 38517205 DOI: 10.1002/anie.202403044] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/12/2024] [Revised: 03/18/2024] [Accepted: 03/19/2024] [Indexed: 03/23/2024]
Abstract
Dual bioorthogonal labeling enables the investigation and understanding of interactions in the biological environment that are not accessible by a single label. However, applying two bioorthogonal reactions in the same environment remains challenging due to cross-reactivity. We developed a pair of differently modified 2'-deoxynucleosides that solved this issue for dual and orthogonal labeling of DNA. Inverse-electron demand Diels-Alder and photoclick reactions were combined to attach two different fluorogenic labels to genomic DNA in cells. Using a small synthetic library of 1- and 3-methylcyclopropenyl-modified 2'-deoxynucleosides, two 2'-deoxyuridines were identified to be the fastest-reacting ones for each of the two bioorthogonal reactions. Their orthogonal reactivity could be evidenced in vitro. Primer extension experiments were performed with both 2'-deoxyuridines investigating their replication properties as substitutes for thymidine and evaluating subsequent labeling reactions on the DNA level. Finally, dual, orthogonal and metabolic fluorescent labeling of genomic DNA was demonstrated in HeLa cells. An experimental procedure was developed combining intracellular transport and metabolic DNA incorporation of the two 2'-deoxyuridines with the subsequent dual bioorthogonal labeling using a fluorogenic cyanine-styryl tetrazine and a fluorogenic pyrene-tetrazole. These results are fundamental for advanced metabolic labeling strategies for nucleic acids in the future, especially for live cell experiments.

Abstract
While bioorthogonal reactions are routinely employed in living cells and organisms, their application within individual organelles remains limited. In this review, we highlight diverse examples of bioorthogonal reactions used to investigate the roles of biomolecules and biological processes as well as advanced imaging techniques within cellular organelles. These innovations hold great promise for therapeutic interventions in personalized medicine and precision therapies. We also address existing challenges related to the selectivity and trafficking of subcellular dynamics. Organelle-targeted bioorthogonal reactions have the potential to significantly advance our understanding of cellular organization and function, provide new pathways for basic research and clinical applications, and shape the direction of cell biology and medical research.

Abstract
A selection of four different 2'-deoxyuridines with three different dienophiles of different sizes was synthesized. Their inverse electron demand Diels-Alder reactivity increases from k2 = 0.15 × 10-2 M-1 s-1 to k2 = 105 × 10-2 M-1 s-1 with increasing ring strain of the dienophiles. With a fluorogenic tetrazine-modified cyanine-styryl dye as reactive counterpart the fluorescence turn-on ratios lie in the range of 21-48 suitable for wash-free cellular imaging. The metabolic DNA labeling was visualized by a dot blot on a semiquantitative level and by confocal fluorescence microscopy on a qualitative level. A clear correlation between the steric demand of the dienophiles and the incorporation efficiency of the modified 2'-deoxyuridines into cellular DNA was observed. Even 2'-deoxyuridines with larger dienophiles, such as norbornene and cyclopropene, were incorporated to a detectable level into the nascent genomic DNA. This was achieved by an optimized way of cell culturing. This expands the toolbox of modified nucleosides for metabolic labeling of nucleic acids in general.

Abstract
Oligonucleotide conjugates are versatile scaffolds that can be applied in DNA-based screening platforms and ligand display or as therapeutics. Several different chemical approaches are available for functionalizing oligonucleotides, which are often carried out on the 5' or 3' end. Modifying oligonucleotides in the middle of the sequence opens the possibility to ligate the conjugates and create DNA strands bearing multiple different ligands. Our goal was to establish a complete workflow that can be applied for such purposes from monomer synthesis to templated ligation. To achieve this, a monomer is required with an orthogonal functional group that can be incorporated internally into the oligonucleotide sequence. This is followed by conjugation with different molecules and ligation with the help of a complementary template. Here, we show the synthesis and the application of a thiol-modified thymidine nucleoside phosphoramidite to prepare ligatable oligonucleotide conjugates. The conjugations were performed both in solution and on solid phase, resulting in conjugates that can be assembled into multivalent oligonucleotides decorated with tissue-targeting peptides using templated ligation.

Abstract
Fluorescent protein-DNA-binding peptides or proteins (FP-DBP) are a powerful means to stain and visualize large DNA molecules on a fluorescence microscope. Here, we constructed 21 kinds of FP-DBPs using various colors of fluorescent proteins and two DNA-binding motifs. From the database of fluorescent proteins (FPbase.org), we chose bright FPs, such as RRvT, tdTomato, mNeonGreen, mClover3, YPet, and mScarlet, which are four to eight times brighter than original wild-type GFP. Additionally, we chose other FPs, such as mOrange2, Emerald, mTurquoise2, mStrawberry, and mCherry, for variations in emitting wavelengths. For DNA-binding motifs, we used HMG (high mobility group) as an 11-mer peptide or a 36 kDa tTALE (truncated transcription activator-like effector). Using 21 FP-DBPs, we attempted to stain DNA molecules and then analyzed fluorescence intensities. Most FP-DBPs successfully visualized DNA molecules. Even with the same DNA-binding motif, the order of FP and DBP affected DNA staining in terms of brightness and DNA stretching. The DNA staining pattern by FP-DBPs was also affected by the FP types. The data from 21 FP-DBPs provided a guideline to develop novel DNA-binding fluorescent proteins.

Abstract
Chemical modification of nucleic acids in living cells can be sterically hindered by tight packing of bioorthogonal functional groups in chromatin. To address this limitation, we report here a dual enhancement strategy for nucleic acid-templated reactions utilizing a fluorogenic intercalating agent capable of undergoing inverse electron-demand Diels-Alder (IEDDA) reactions with DNA containing 5-vinyl-2'-deoxyuridine (VdU) or RNA containing 5-vinyl-uridine (VU). Reversible high-affinity intercalation of a novel acridine-tetrazine conjugate "PINK" (KD =5±1 μM) increases the reaction rate of tetrazine-alkene IEDDA on duplex DNA by 60 000-fold (590 M-1 s-1 ) as compared to the non-templated reaction. At the same time, loss of tetrazine-acridine fluorescence quenching renders the reaction highly fluorogenic and detectable under no-wash conditions. This strategy enables live-cell dynamic imaging of acridine-modified nucleic acids in dividing cells.

Abstract
Labeling of nucleic acids is required for many studies aiming to elucidate their functions and dynamics in vitro and in cells. Out of the numerous labeling concepts that have been devised, covalent labeling provides the most stable linkage, an unrivaled choice of small and highly fluorescent labels and - thanks to recent advances in click chemistry - an incredible versatility. Depending on the approach, site-, sequence- and cell-specificity can be achieved. DNA and RNA labeling are rapidly developing fields that bring together multiple areas of research: on the one hand, synthetic and biophysical chemists develop new fluorescent labels and isomorphic nucleobases as well as faster and more selective bioorthogonal reactions. On the other hand, the number of enzymes that can be harnessed for post-synthetic and site-specific labeling of nucleic acids has increased significantly. Together with protein engineering and genetic manipulation of cells, intracellular and cell-specific labeling has become possible. In this review, we provide a structured overview of covalent labeling approaches for nucleic acids and highlight notable developments, in particular recent examples. The majority of this review will focus on fluorescent labeling; however, the principles can often be readily applied to other labels. We will start with entirely chemical approaches, followed by chemo-enzymatic strategies and ribozymes, and finish with metabolic labeling of nucleic acids. Each section is subdivided into direct (or one-step) and two-step labeling approaches and will start with DNA before treating RNA.

Abstract
Labelling of nucleic acids as biologically important cellular components is a crucial prerequisite for the visualization and understanding of biological processes. Efficient bioorthogonal chemistry and in particular cycloadditions fullfill the requirements for cellular applications. The broadly applied Cu(i)-catalyzed azide-alkyne cycloaddition (CuAAC), however, is limited to labellings in vitro and in fixed cells due to the cytotoxicity of copper salts. Currently, there are three types of copper-free cycloadditions used for nucleic acid labelling in the cellular environment: (i) the ring-strain promoted azide-alkyne cycloaddition (SPAAC), (ii) the "photoclick" 1,3-dipolar cycloadditions, and (iii) the Diels-Alder reactions with inverse electron demand (iEDDA). We review only those building blocks for chemical synthesis on solid phase of DNA and RNA and for enzymatic DNA and RNA preparation, which were applied for labelling of DNA and RNA in situ or in vivo, i.e. in the cellular environment, in fixed or in living cells, by the use of bioorthogonal cycloaddition chemistry. Additionally, we review the current status of orthogonal dual and triple labelling of DNA and RNA in vitro to demonstrate their potential for future applications in situ or in vivo.

Abstract
We report here a deep mechanistic study of the "click" ortho-quinone methide (oQM) cycloaddition between ortho-quinolinone quinone methide (oQQM) and thio-vinyl ether (TV), named as TQ-ligation. DFT calculations revealed the unexpected fact that dehydration of oQQM precursors is the rate-determining step of this transformation, and two highly reactive oQQM precursors were predicted. Guided by the calculations, a new "click" oQM cycloaddition which shows significantly improved kinetics and remarkable efficiency on protein labeling was developed.

Abstract
Quinone methides (QMs) are transient reactive species that can be efficiently generated from stable precursors under a variety of biocompatible conditions. Due to their electrophilic nature, QMs have been widely explored as cross-linking agents of DNA and proteins under physiological conditions. However, QMs also have a diene character and can irreversibly react via Diels-Alder reaction with electron-rich dienophiles. This particular reactivity has been recently exploited to label biomolecules with fluorophores in living cells. QMs are characterised by two unique properties that make them ideal candidates for chemical biology applications: i) they can be efficiently generated in situ from very stable precursors by means of bio-orthogonal protocols ii) they are reversible cross-linking agents, making them suitable for "catch and release" target-enrichment experiments. Nevertheless, there are only few examples reported to date that truly take advantage of QMs unique chemistry in the context of chemical-biology assay development. In this review, we will examine the most relevant examples that illustrate the benefit of using QMs for chemical biology purposes and we will anticipate novel approaches to further their applications in biologically relevant contexts.
