Synthesis of activated pyrimidine ribonucleotides in prebiotically plausible conditions
TLDR
It is shown that activated pyrimidine ribonucleotides can be formed in a short sequence that bypasses free ribose and the nucleobases, and instead proceeds through arabinose amino-oxazoline and anhydronucleoside intermediates. Expand
Prebiotically plausible oligoribonucleotide ligation facilitated by chemoselective acetylation.
TLDR
It is shown that the 2'-hydroxyl group of oligoribonucleotide-3'-phosphates can be chemoselectively acetylated in water under prebiotically credible conditions, which allows rapid and efficient template-directed ligation. Expand
Synthesis of a library of fucosylated glycoclusters and determination of their binding toward Pseudomonas aeruginosa lectin B (PA-IIL) using a DNA-based carbohydrate microarray.
TLDR
16 fucosylated glycoclusters with antenna-like, linear, or crown-like spatial arrangements were synthesized using a combination of DNA solid-phase synthesis and alkyne azide 1,3-dipolar cycloaddition and their binding properties toward PA-IIL were evaluated, and it was suggested that the antenna- like scaffold was preferred to linear or Crown-like glycocluster.

Structure binding relationship of galactosylated Glycoclusters toward Pseudomonas aeruginosa lectin LecA using a DNA-based carbohydrate microarray.
TLDR
The results showed that the binding profile of LecA to galactosylated clusters was dependent on both the core and the linker and also that the optimal linker was different for each core. Expand
Differential effects on allele selective silencing of mutant huntingtin by two stereoisomers of α,β-constrained nucleic acid.
We describe the effects of introducing two epimers of neutral backbone α,β-constrained nucleic acid (CNA) on the activity and allele selectivity profile of RNase H active antisense oligonucleotidesExpand
Synthesis of homo- and heterofunctionalized glycoclusters and binding to Pseudomonas aeruginosa lectins PA-IL and PA-IIL.
Homo- and heterofunctionalized glycoclusters with galactose and/or fucose residues targeting both PA-IL and PA-IIL lectins of Pseudomonas aeruginosa were synthesized using "Click" chemistry and DNAExpand
Direct preparation of nucleoside vinyl disulfides from 2-(trimethylsilyl)ethyl sulfides, an access to vinylthiols.
TLDR
The easy preparation of vinyl disulfides from stable silyl sulfides without formation of oxidizable and/or unstable thiols through this reaction should offer new perspectives in vinylthiol chemistry. Expand
Anti-retroviral and cytostatic activity of 2',3'-dideoxyribonucleoside 3'-disulfides.
TLDR
The synthesis, antiviral and cytostatic effects of nucleosides bearing a 3'-disulfide function as prodrugs of potentially active 3'-mercaptonucleotides are reported and it is suggested that a phosphorylation step involving thymidine kinase is necessary for the eventual antiviral activity of theThymidine nucleoside. Expand
Stabilization of hairpins and bulged secondary structures of nucleic acids by single incorporation of α,β-D-CNA featuring a gauche(+) alpha torsional angle
A constrained dinucleotide unit featuring a gauche(+) alpha torsional angle configuration was used to stabilize DNA hairpin or bulged structures. Large five nucleotides having looped hairpinExpand
DNA Three Way Junction Core Decorated with Amino Acids-Like Residues-Synthesis and Characterization †
Construction and physico-chemical behavior of DNA three way junction (3WJ) functionalized by protein-like residues (imidazole, alcohol and carboxylic acid) at unpaired positions at the core isExpand
