Assessment of the Potential Energy Hypersurfaces in Thymine within Multiconfigurational Theory: CASSCF vs. CASPT2

open access: yesMolecules, 2016
The present study provides new insights into the topography of the potential energy hypersurfaces (PEHs) of the thymine nucleobase in order to rationalize its main ultrafast photochemical decay paths by employing two methodologies based on the complete ...

A function of thymine DNA glycosylase-initiated DNA repair in maintaining epigenome stability [PDF]

open access: yes, 2013
The Thymine DNA Glycosylase (TDG) was initially discovered by its ability to excise the deamination products of cytosine and 5-methylcytosine (5-mC), and therefore thought to initiate base excision repair (BER) of the resulting G•U and G•T mismatches.

Photochemistry of Thymine in Protic Polar Nanomeric Droplets Using Electrostatic Embeding TD-DFT/MM

open access: yesMolecules, 2021
Thymine photochemistry is important for understanding DNA photodamage. In the gas phase, thymine undergoes a fast non-radiative decay from S2 to S1. In the S1 state, it gets trapped for several picoseconds until returning to the ground-state S0. Here, we

The behavior of triplet thymine in a model B-DNA strand. Energetics and spin density localization revealed by ab initio molecular dynamics simulations. [PDF]

open access: yes, 2021
Among the natural occurring nucleobases, thymine presents the lowest triplet state, hence it represents a hotspot for energy transfer and photosensitization.

Discovery of Cisplatin Binding to Thymine and Cytosine on a Single-Stranded Oligodeoxynucleotide by High Resolution FT-ICR Mass Spectrometry

open access: yesMolecules, 2019
The clinically widely-used anticancer drug, cisplatin, binds strongly to DNA as a DNA-damaging agent. Herein, we investigated the interaction of cisplatin with a 15-mer single-stranded C,T-rich oligodeoxynucleotide, 5′-CCTT4CTT7G8C9T10TCTCC-3′

DNA Nucleobase Under Ionizing Radiation: Unexpected Proton Transfer by Thymine Cation in Water Nanodroplets [PDF]

open access: yes, 2020
The effects of ionizing radiation on DNA constituents is a widely studied fundamental process using experimental and computational techniques. In particular radiation effects on nucleobases are usually tackled by mass spectrometry in which the nucleobase

Probing the Molecular Frame of Uracil and Thymine with High Harmonic Generation Spectroscopy [PDF]

open access: yes, 2020
In this work we present computed high-harmonic generation (HHG) spectra of uracil and thyminemolecules, by means of the real-time time-dependent formulation of Gaussian-based configurationinteraction with single excitations (RT-TD-CIS).
