Abstract
A straightforward and efficient methodology has been employed for the synthesis of a diverse set of base-modified fluorescent nucleoside conjugates via Cu(I)-catalysed cycloaddition reaction of 5-ethynyl-2',3',5'-tri-O-acetyluridine/3',5'-di-O-acetyl-2'-deoxyuridine with 4-(azidomethyl)-N9-(4'-aryl)-9,10-dihydro-2H,8H-chromeno[8,7-e][1,3]oxazin-2-ones in tBuOH to afford the desired 1,2,3-triazoles in 92-95% yields. Treatment with NaOMe/MeOH resulted in the final deprotected nucleoside analogues. The synthesized 1,2,3-triazoles demonstrated a significant emission spectrum, featuring two robust bands in the region from 350-500 nm (with excitation at 300 nm) in fluorescence studies. Photophysical investigations revealed a dual-emissive band with high fluorescence intensity, excellent Stokes shift (140-164 nm) and superior quantum yields (0.068-0.350). Furthermore, the electronic structures of the synthesized triazoles have been further verified by DFT studies. Structural characterization of all synthesized compounds was carried out using various analytical techniques, including IR, 1H-NMR, 13C-NMR, 1H-1H COSY, 1H-13C HETCOR experiments, and HRMS measurements. The dual-emissive nature of these nucleosides would be a significant contribution to nucleoside chemistry as there are limited literature reports on the same.

Abstract
Modified bright fluorescent nucleosides that respond to the microenvironment have great potential as probes. A series of novel 8-(phenylethynyl)phenylated 2-amino-2'-deoxyadenosine and 2'-deoxyisoguanosine derivatives have been synthesized by Sonogashira-type coupling reaction and Suzuki reaction. The maximum emission of the new compounds is in the visible region, with strong solvatochromicity and pH-dependent fluorescent properties. Furthermore, some of them exhibit bright fluorescence emissions in various solvents (ε × Φ = 4000-39,000 cm-1 M-1). These consequences indicate that purine analogues could respond to the microenvironment and serve as promising fluorescent probes.Supplemental data for this article is available online at https://doi.org/10.1080/15257770.2021.2004418 .

Abstract
The synthesis of 2'-deoxycytidine and its 5'-O-triphosphate bearing solvatochromic acetophenyl-thienyl-aniline fluorophore was developed using the Sonogashira cross-coupling reaction as the key step. The triphosphate was used for polymerase synthesis of labelled DNA. The labelled nucleotide or DNA exerted weak red fluorescence when excited at 405 nm, but a significant colour change (to yellow or green) and light-up (up to 20 times) was observed when the DNA probes interacted with proteins or lipids.

Abstract
Thymidine triphosphate bearing benzylidene-tetrahydroxanthylium near-IR fluorophore linked to the 5-methyl group via triazole was synthesized through the CuAAC reaction and was used for polymerase synthesis of labelled DNA probes. The fluorophore lights up upon incorporation to DNA (up to 348-times) presumably due to interactions in major groove and the fluorescence further increases in the single-stranded oligonucleotide. The labelled dsDNA senses binding of small molecules and proteins by a strong decrease of fluorescence. The nucleotide was used as a light-up building block in real-time PCR for detection of SARS-CoV-2 virus.

Abstract
Cytosine 2'-deoxyribonucleoside dCTBdp and its triphosphate (dCTBdpTP) bearing tetramethylated thiophene-bodipy fluorophore attached at position 5 were designed and synthesized. The green fluorescent nucleoside dCTBdp showed a perfect dependence of fluorescence lifetime on the viscosity. The modified triphosphate dCTBdpTP was substrate to several DNA polymerases and was used for in vitro enzymatic synthesis of labeled oligonucleotides (ONs) or DNA by primer extension. The labeled single-stranded ONs showed a significant decrease in mean fluorescence lifetime when hybridized to the complementary strand of DNA or RNA and were also sensitive to mismatches. The labeled dsDNA sensed protein binding (p53), which resulted in the increase of its fluorescence lifetime. The triphosphate dCTBdpTP was transported to live cells where its interactions could be detected by FLIM but it did not show incorporation to genomic DNA in cellulo.

Abstract
The self-priming synthesis of multiply modified DNA by the extension of repeating unit duplex "oligoseeds" provides a source of versatile DNA. Sterically-demanding nucleotides 5-Br-dUTP, 7-deaza-7-I-dATP, 6-S-dGTP, 5-I-dCTP as well as 5-(octadiynyl)-dCTP were incorporated into two extending oligoseeds; [GATC]5 /[GATC]5 and [A4 G]4 /[CT4 ]4 . The products contained modifications on one or both strands of DNA, demonstrating their recognition by the polymerase as both template (reading) and substrate (writing). Nucleobase modifications that lie in the major groove were reliably read and written by the polymerase during the extension reaction, even when bulky or in contiguous sequences. Repeat sequence DNA over 500 bp long, bearing four different modified units was produced by this method. The number, position and type of modification, as well as the overall length of the DNA can be controlled to yield designer DNA that offers sequence-determined sites for further chemical adaptations, targeted small molecule binding studies, or sensing and sequencing applications.

Abstract
Microenvironment-sensitive fluorescent nucleosides present attractive advantages over single-emitting dyes for sensing inter-biomolecular interactions involving DNA. Herein, we report the rational design and synthesis of triazolyl push-pull fluorophore-labeled uridines via the intermediacy of C5-[4-(2-propynyl(methyl)amino)]phenyl acetylene as a universal linker. The synthesized nucleosides showed interesting solvatochromic characteristic and/or intramolecular charge transfer (ICT) features. A few of them also exhibited dual-emitting characteristics evidencing our designing concept. The HOMO-LUMO distribution showed that the emissive states of these nucleosides were characterized with more significant electron redistribution between the C5-[4-(2-propynyl(methyl)amino)]phenyl triazolyl donor moiety and the aromatic chromophores linked to it, leading to modulated emission property. The solvent polarity sensitivity of these nucleosides was also tested. The synthesized triazolyl benzonitrile (10C), naphthyl (10E), and pyrenyl (10G) nucleosides were found to exhibit interesting ICT and dual (LE/ICT) emission properties. The dual-emitting pyrenyl nucleoside maintained a good ratiometric response in the BSA protein microenvironment, enabling the switch-on ratiometric sensing of BSA as the only protein biomolecule. Thus, it is expected that the new fluorescent nucleoside analogues would be useful in designing DNA probes for nucleic acid analysis or studying DNA-protein interactions via a drastic change in fluorescence response due to a change in micropolarity.

Abstract
10-23 DNAzyme is a small catalytic DNA molecule. Studies on its conformation in solution are critical for understanding its catalytic mechanism and functional optimization. Based on our previous research, two fluorescent nucleoside analogues 1 and 2 were designed for the introduction of a pyrenyl group at one of the five dA residues in the catalytic core and the unpaired adenosine residue in its full-DNA substrate, respectively. Ten pyrenyl-pyrenyl pairs are formed in the DNAzyme-substrate complexes in solution for sensing the spacial positions of the five dA residues relative to the cleavage site using fluorescence spectra. The position-dependent quenching effect of pyrene emission fluorescence by nucleobases, especially the pyrenyl-pyrenyl interaction, was observed for some positions. The adenine residues in the 3'-part of the catalytic loop seem to be closer to the cleavage site than the adenine residues in the 5'-part, which is consistent with the molecular dynamics simulation result. The catalytic activities and Tm changes also confirmed the effect of the pyrenyl-nucleobase and pyrenyl-pyrenyl pair interactions. Together with functional group mutations, catalytically relevant nucleobases will be identified for understanding the catalytic mechanism of 10-23 DNAzyme.

Abstract
Sequence-specific detection of nucleic acids has been intensively studied in the field of molecular diagnostics. In particular, the detection and analysis of single-nucleotide polymorphisms (SNPs) is crucial for the identification of disease-causing genes and diagnosis of diseases. Sequence-specific hybridization probes, such as molecular beacons bearing the fluorophore and quencher at both ends of the stem, have been developed to enable DNA mutation detection. Interestingly, DNA mutations can be detected using fluorescently labeled oligonucleotide probes with only one fluorophore. This review summarizes recent research on single-labeled oligonucleotide probes that exhibit fluorescence changes after encountering target nucleic acids, such as guanine-quenching probes, cyanine-containing probes, probes containing a fluorophore-labeled base, and microenvironment-sensitive probes.

Most fluorescent nucleoside analogues are quenched when base stacked and some maintain their brightness, but there has been little progress toward developing nucleoside analogues that markedly increase their fluorescence upon duplex formation. Here, we report on the design and synthesis of a new tricyclic cytidine analogue, 8-diethylamino-tC (8-DEA-tC), that responds to DNA duplex formation with up to a 20-fold increase in fluorescent quantum yield as compared with the free nucleoside, depending on neighboring bases. This turn-on response to duplex formation is the greatest of any reported nucleoside analogue that can participate in Watson-Crick base pairing. Measurements of the quantum yield of 8-DEA-tC mispaired with adenosine and, separately, opposite an abasic site show that there is almost no fluorescence increase without the formation of correct Watson-Crick hydrogen bonds. Kinetic isotope effects from the use of deuterated buffer show that the duplex protects 8-DEA-tC against quenching by excited state proton transfer. These results, supported by DFT calculations, suggest a rationale for the observed photophysical properties that is dependent on duplex integrity and the electronic structure of the analogue.

Abstract
A nucleoside bearing a solvatochromic push-pull fluorene fluorophore (dCFL ) was designed and synthesized by the Sonogashira coupling of alkyne-linked fluorene 8 with 5-iodo-2'-deoxycytidine. The fluorene building block 8 and labeled nucleoside dCFL exerted bright fluorescence with significant solvatochromic effect providing emission maxima ranging from 421 to 544 nm and high quantum yields even in highly polar solvents, including water. The solvatochromism of 8 was studied by DFT and ADC(2) calculations to show that, depending on the polarity of the solvent, emission either from the planar or the twisted conformation of the excited state can occur. The nucleoside was converted to its triphosphate variant dCFLTP which was found to be a good substrate for DNA polymerases suitable for the enzymatic synthesis of oligonucleotide or DNA probes by primer extension or PCR. The fluorene-linked DNA can be used as fluorescent probes for DNA-protein (p53) or DNA-lipid interactions, exerting significant color changes visible even to the naked eye. They also appear to be suitable for time-dependent fluorescence shift studies on DNA, yielding information on DNA hydration and dynamics.

Abstract
Four 6-substituted 4-amino-pyrimido[4,5-b]indole 2'-deoxyribonucleoside triphosphates (dA(BX)TPs) were prepared by glycosylation of 4,6-dichloropyrimidoindole followed by ammonolysis, cross-coupling and triphosphorylation. They were found to be moderate to good substrates for DNA polymerases in primer extension. They also exerted fluorescence with emission maxima 335-378nm. When incorporated to oligonucleotide probes, they did not show significant mismatch discrimination but the 6-benzofuryl 4-amino-pyrimido[4,5-b]indole nucleotide displayed a useful sensitivity to protein binding in experiment with SSB protein.

Abstract
Pyrene-labeled 3-deaza-2'-deoxyadenosine comprising a non-π-conjugated linker (py3z)A (1) was synthesized and its photophysical properties were investigated. Oligodeoxynucleotide (ODN) probes containing (py3z)A (1) exhibited remarkable fluorescence quenching only when the opposite base of the complementary strand was the perfectly matched thymine. Such fluorescence quenching-based ODN probes exhibited excellent on-off switching properties, making them useful tools for single nucleotide polymorphism (SNP) genotyping and for the identification of target genes and structural studies of nucleic acids.

Abstract
Fluorescent base analogues comprise a group of increasingly important molecules for the investigation of nucleic acid structure, dynamics, and interactions with other molecules. Herein, we report on the quantum chemical calculation aided design, synthesis, and characterization of four new putative quadracyclic adenine analogues. The compounds were efficiently synthesized from a common intermediate through a two-step pathway with the Suzuki-Miyaura coupling as the key step. Two of the compounds, qAN1 and qAN4, display brightnesses (εΦF) of 1700 and 2300, respectively, in water and behave as wavelength-ratiometric pH probes under acidic conditions. The other two, qAN2 and qAN3, display lower brightnesses but exhibit polarity-sensitive dual-band emissions that could prove useful to investigate DNA structural changes induced by DNA-protein or -drug interactions. The four qANs are very promising microenvironment-sensitive fluorescent adenine analogues that display considerable brightness for such compounds.

Abstract
New fluorescent nucleosides and nucleoside triphosphate (dNTPs) analogs bearing the F-Bodipy fluorophore linked through a short, flexible nonconjugate tether were synthesized. The Bodipy-labeled dNTPs were substrates for several DNA polymerases which incorporated them into DNA in primer extension, nicking enzyme amplification reaction, and polymerase chain reaction. The fluorescence of F-Bodipy is not quenched upon incorporation in DNA and can be detected both in solutions and on gels.
