Synthesis and Structural Study of Some Pyrimidinium Hexafluoridosilicates

open access: yesActa Chimica Slovenica, 2015
The synthesis and spectroscopic characterization of some pyrimidinium hexafluoridosilicate salts with the formula (RH)2[SiF]6 (where R = 2-aminopyrimidine (1), cytosine (2) and 5-cyanocytosine (3)) is obtained in the reaction of SiO2 with hydrofluoric ...

Theoretical and experimental study of the vibrational spectra of 1.5-dimethylcytosine [PDF]

open access: yes, 2008
The Raman spectra of the solid 1,5-dimethylcytosine and the FTIR spectra at room and low temperatures respectively have been registered. Quantum mechanical calculations of energies, geometries and vibrational wavenumbers were carried out by using ab ...

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′

Excited States of Proton-bound DNA/RNA Base Homo-dimers: Pyrimidines [PDF]

open access: yes, 2014
We are presenting the electronic photo fragment spectra of the protonated pyrimidine DNA bases homo-dimers. Only the thymine dimer exhibits a well structured vibrational progression, while protonated monomer shows broad vibrational bands. This shows that

CGGBP1-regulated cytosine methylation at CTCF-binding motifs resists stochasticity

open access: yesBMC Genetics, 2020
Background The human CGGBP1 binds to GC-rich regions and interspersed repeats, maintains homeostasis of stochastic cytosine methylation and determines DNA-binding of CTCF.

Communication: UV photoionization of cytosine catalyzed by Ag+ [PDF]

open access: yes, 2015
The photo-induced damages of DNA in interaction with metal cations, which are found in various environments, still remain to be characterized. In this paper, we show how the complexation of a DNA base (cytosine (Cyt)) with a metal cation (Ag+) changes ...

Cytosine Arabinoside-Induced Vasculitis [PDF]

open access: yesMayo Clinic Proceedings, 1998
Dermatologic side effects of cytosine arabinoside (ara-C) are rare and most commonly occur after high-dose (more than 100 to 200 mg/m2 per day) therapy has been administered for several days. Although vascular reactions after combination chemotherapeutic regimens with ara-C have been anecdotally described, they have not been previously reported after ...

In silico structural analysis of sequences containing 5-hydroxymethylcytosine reveals its potential as binding regulator for development, ageing and cancer-related transcription factors

open access: yesEpigenetics, 2021
The presence of 5-hydroxymethyl cytosine in DNA has been previously associated with ageing. Using in silico analysis of normal liver samples we presently observed that in 5-hydroxymethyl cytosine sequences, DNA methylation is dependent on the co-presence
