Photoinduced Formation Mechanism of the Thymine–Thymine (6–4) Adduct [PDF]

Journal of Physical Chemistry B, 2013
The photoinduced mechanism leading to the formation of the thymine-thymine (6-4) photolesion has been studied by using the CASPT2//CASSCF approach over a dinucleotide model in vacuo. Following light absorption, localization of the excitation on a single thymine leads to fast singlet-triplet crossing that populates the triplet (3)(nπ*) state of thymine.

Adhesive Materials Utilizing a Thymine–Adenine Interaction and Thymine Photodimerization

ACS Macro Letters, 2015
A cross-linking reagent having two adenine units was mixed with polymers bearing thymine units to form adhesive materials utilizing both intermolecular hydrogen bonding and in situ formation of covalent bonds. In the case of 58 mol % of adenine units relative to thymine units, formation of intermolecular hydrogen bonds because of a thymine-adenine ...

Thymine-metal ion interactions: relevance for thymine quartet structures

JBIC Journal of Biological Inorganic Chemistry, 2001
Apart from their function as counter ions for the charge neutralization of nucleic acids, alkali metal ions play important roles in stabilizing particular multistranded nucleic acids, e.g. guanine quartets in telomeres and uracil (U) or thymine (T) quartets. Here X-ray crystal structure determinations of a series of alkali metal ions (Na+, K+, Rb+, Cs+)

Thy-AuNP-AgNP Hybrid Systems for Colorimetric Determination of Copper (II) Ions Using UV-Vis Spectroscopy and Smartphone-Based Detection

Nanomaterials, 2022
A colorimetric probe based on a hybrid sensing system of gold nanoparticles (AuNPs), silver nanoparticles (AgNPs), and thymine (Thy) was developed for easy and rapid detection of copper (II) ions (Cu2+) in solution. The underlying principle of this probe

Ru-Controlled Thymine Tautomerization Frozen by a k¹(O)-, k²(N,O)-Metallacycle: An Experimental and Theoretical Approach

Molecules, 2023
The reaction of mer-(Ru(H)2(CO)(PPh3)3) (1) with one equivalent of thymine acetic acid (THAcH) unexpectedly produces the macrocyclic dimer k1(O), k2(N,O)-(Ru(CO)(PPh3)2THAc)2 (4) and, concomitantly, the doubly coordinated species k1(O), k2(O,O)-(Ru(CO ...

Density Functional Method Study on the Cooperativity of Intermolecular H-bonding and π-π⁺ Stacking Interactions in Thymine-[C_nmim]Br (n = 2, 4, 6, 8, 10) Microhydrates

Molecules, 2022
The exploration of the ionic liquids’ mechanism of action on nucleobase’s structure and properties is still limited. In this work, the binding model of the 1-alkyl-3-methylimidazolium bromide ([Cnmim]Br, n = 2, 4, 6, 8, 10) ionic liquids to the thymine ...

Tautomerisation Mechanisms in the Adenine-Thymine Nucleobase Pair During DNA Strand Separation [PDF]

, 2022
The adenine-thymine tautomer (A*-T*) has previously been discounted as a spontaneous mutagenesis mechanism due to the energetic instability of the tautomeric configuration.
