Advances in the synthesis of 5-and 6-substituted uracil derivatives
(Routledge Journals, Taylor & Francis Ltd, 2009-01)
The uracil unit is one of the most important structures in life, it being part of the building blocks of RNA and DNA and other natural products; therefore, it is not surprising that uracil derivatives have important ...
New Fluorinated Pyrazol and Uracil Derivatives: Synthesis and Biological Activity
(American Chemical Society Inc, 2009)
Both fluorinated pyrazoles and uracils are compounds that display very interesting biological activity. This chapter reviews recent work or our group in the development of synthetic strategies for the preparation of new ...
Síntese de porfirinas contendo grupos do tipo uracil fundidos nas posições β-pirrólicas
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Química - PPGQ, 2014-07-28)
In this work the synthesis of new porphyrin derivatives were proposed. The preparations of new compounds containing uracil groups at β-pirrolic position were studied based on their interest in organics synthesis. We ...
Tautomerism of uracil and related compounds: A mass spectrometry study
(SAGE Publications Ltd, 2018-04)
It has been demonstrated that uracil has a preponderant tautomeric form, but it is also known that different tautomers co-exist in this equilibrium. In this work, mass spectrometry is used as a helpful tool to analyse the ...
Thymine hydroperoxide as a potential source of singlet molecular oxygen in DNA
(ELSEVIER SCIENCE INC, 2009)
The decomposition of organic hydroperoxides into peroxyl radicals is a potential source of singlet molecular oxygen [O(2) ((1)Delta(g))] in biological systems. This study shows that 5-(hydroperoxymethyl)uracil (5-HPMU), a ...
Eucalyptus ESTs corresponding to the enzyme glutamine synthetase and the protein D1, sites of action of herbicides that cause oxidative stress
(2005-12-01)
This work was aimed at locating Eucalyptus ESTs corresponding to the GS enzyme (Glutamine Synthetase, EC = 6.3.1.2) and to the D1 protein, which are directly related to resistance to herbicides that promote oxidative stress. ...
