Thymine-Modified Nanocarrier for Doxorubicin Delivery in Glioblastoma Cells

open access: yesMolecules, 2023
Brain tumor glioblastoma is one of the worst types of cancer. The blood–brain barrier prevents drugs from reaching brain cells and shields glioblastoma from treatment.

Prebiotic Route to Thymine from Formamide—A Combined Experimental–Theoretical Study

open access: yesMolecules, 2021
Synthesis of RNA nucleobases from formamide is one of the recurring topics of prebiotic chemistry research. Earlier reports suggest that thymine, the substitute for uracil in DNA, may also be synthesized from formamide in the presence of catalysts ...

Adenine and Thymine Effect on Quartz Dissolution at Different Artificial Seawaters

open access: yesOrbital: The Electronic Journal of Chemistry, 2018
According to Bernal (1951) minerals may have played important roles in the origin of life such as: protect biomolecules against degradation by UV radiation or hydrolysis, pre-concentrate biomolecules from prebiotic seas and formation of polymers.

Investigation of the spin-forbidden process in thymine [PDF]

open access: yesHemijska Industrija, 2012
The intersystem crossing rate from the lowest singlet to the lowest triplet state of thymine was studied by means of the ab initio methods. The rate was calculated employing the time-dependent approach based on the correlation function.

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.

Novel Hg2+-imprinted polymers based on thymine–Hg2+–thymine interaction for highly selective preconcentration of Hg2+ in water samples [PDF]

open access: yes, 2012
A novel functional monomer T-IPTS, 3-isocyanatopropyltriethoxysilane (IPTS) bearing thymine (T) bases, was synthesized for imprinting Hg2+. Then a novel Hg2+ ionic imprinted polymers (IIPs) based on thymine-Hg2+-thymine (T-Hg2+-T) interactions, i.e.

A Simple and Highly Sensitive Thymine Sensor for Mercury Ion Detection Based on Surface Enhanced Raman Spectroscopy and the Mechanism Study

open access: yesNanomaterials, 2017
Mercury ion (Hg2+) is recognized as one of the most toxic metal ions for the environment and for human health. Techniques utilized in the detection of Hg2+ are an important factor.

Synthesis of new dipeptides based on uracil and thymine and investigation of the molecular docking of these compounds as inhibitors of quorum sensing system in Pseudomonas aeruginosa [PDF]

open access: yesشیمی کاربردی روز, 2019
In this study, due to the importance of dipeptide compounds in diagnosis of disease or as drug compounds, new dipeptide compounds were synthesized using pyrimidine derivatives of thymine and uracil.

A mutant of uracil DNA glycosylase that distinguishes between cytosine and 5-methylcytosine [PDF]

open access: yes, 2014
We demonstrate that a mutant of uracil DNA glycosylase (N123D:L191A) distinguishes between cytosine and methylcytosine. Uracil DNA glycosylase (UDG) efficiently removes uracil from DNA in a reaction in which the base is flipped into the enzyme’s active ...
