α-<span>D</span>-2′-Deoxyadenosine, an irradiation product of canonical DNA and a component of anomeric nucleic acids: crystal structure, packing and Hirshfeld surface analysis Open
α-D-2′-Deoxyribonucleosides are products of the γ-irradiation of DNA under oxygen-free conditions and are constituents of anomeric DNA. They are not found as natural building blocks of canonical DNA. Reports on their conformational propert…

DNA Strand Displacement with Base Pair Stabilizers: Purine‐2,6‐Diamine and 8‐Aza‐7‐Bromo‐7‐Deazapurine‐2,6‐Diamine Oligonucleotides Invade Canonical DNA and New Fluorescent Pyrene Click Sensors Monitor the Reaction Open
Purine‐2,6‐diamine and 8‐aza‐7‐deaza‐7‐bromopurine‐2,6‐diamine 2’‐deoxyribonucleosides ( 1 and 2 ) were implemented in isothermal DNA strand displacement reactions. Nucleoside 1 is a weak stabilizer of dA‐dT base pairs, nucleoside 2 evokes…

Anomeric DNA Strand Displacement with α‐D Oligonucleotides as Invaders and Ethidium Bromide as Fluorescence Sensor for Duplexes with α/β‐, β/β‐ and α/α‐D Configuration Open
DNA strand displacement is a technique to exchange one strand of a double stranded DNA by another strand (invader). It is an isothermal, enzyme free method driven by single stranded overhangs (toeholds) and is employed in DNA amplification…

Anomeric DNA: Functionalization of α‐<span>d</span> Anomers of 7‐Deaza‐2′‐deoxyadenosine and 2′‐Deoxyuridine with Clickable Side Chains and Click Adducts in Homochiral and Heterochiral Double Helices Open
Anomeric base pairs in heterochiral DNA with strands in the α‐ d and β‐ d configurations and homochiral DNA with both strands in α‐ d configuration were functionalized. The α‐ d anomers of 2′‐deoxyuridine and 7‐deaza‐2′‐deoxyadenosine were…

Anomeric and Enantiomeric 2’‐Deoxycytidines: Base Pair Stability in the Absence and Presence of Silver Ions Open
Dodecamer duplex DNA containing anomeric (α/β‐ d ) and enantiomeric (β‐ l /β‐ d ) 2’‐deoxycytidine mismatches was studied with respect to base pair stability in the absence and presence of silver ions. Stable duplexes with silver‐mediated …

5‐Aza‐7‐deazaguanine–Isoguanine and Guanine–Isoguanine Base Pairs in Watson–Crick DNA: The Impact of Purine Tracts, Clickable Dendritic Side Chains, and Pyrene Adducts Open
The Watson–Crick coding system depends on the molecular recognition of complementary purine and pyrimidine bases. Now, the construction of hybrid DNAs with Watson–Crick and purine–purine base pairs decorated with dendritic side chains was …
