Abstract
We designed and synthesized nucleosides bearing aminophenyl- or aminonaphthyl-3-methoxychromone fluorophores attached at position 5 of cytosine or thymine and converted them to nucleoside triphosphates. The fluorophores showed solvatochromic fluorescence with strong fluorescence at 433-457 nm in non-polar solvents and very weak fluorescence at 567 nm in alcohols. The nucleosides and nucleotides also showed only negligible fluorescence in alcohols or water. The triphosphates were substrates for DNA polymerase in the enzymatic synthesis of modified DNA probes that showed only very weak fluorescence in aqueous buffer but a significant light-up and blue shift were observed when they interacted with proteins (histone H3.1 or p53 for double-stranded DNA probes or single-strand binding protein for single-stranded oligonucleotide probes). Hence, nucleotides have good potential in the construction of DNA sensors for studying protein-DNA interactions. The modified dNTPs were also transported into cells using a cyclodextrin-based transporter but they were not incorporated into the genomic DNA.

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
A new methodology for site-selective and stereoselective C-H functionalization of aminocyclopropanes via directed remote lithiation has been developed. Treatment of N-directing group (DG = pivaloyl, tetramethylsuccinimidoyl) arylcyclopropanes with t-BuLi results in a clean β-lithiation and, following quench with electrophiles, leads to a range of cyclopropane derivatives. Sequential double lithiation-methylation to give a dimethylated cyclopropane has been achieved. X-ray, NMR, and computational studies allow rationalization of syn-DG β-deprotonation selectivity via a DG-lithium base coordinated complex.
