Electrofluorination of uracil

Journal of Fluorine Chemistry, 1980
Abstract In view of the importance of the medical applications of fluorinated uracil and derivatives, synthetic methods directed to obtain such compounds are of particular interest. Several aspects of the electrochemical fluorination of uracil in different experimental conditions will be discussed.

Substituted Uracil Herbicides

Science, 1962
Explorations in the pyrimidine series have led to the discovery of highly active herbicides, of which 3-butyl-6-methyluracil and 5-bromo-3-isopropyl-6-methyluracil are examples.

The Synthesis of Uracils as Anticonvulsants*

Journal of the American Pharmaceutical Association (Scientific ed.), 1955
Abstract A convenient laboratory synthesis has been devised by which a series of new 5‐alkyluracils has been prepared for evaluation as anti‐convulsants. Certain other 5‐substituted uracils and their N,N‐dimethyl derivatives, and related compounds, have also been synthesized.

The role of the environment in the ion induced fragmentation of uracil.

Physical Chemistry, Chemical Physics - PCCP, 2016
The fragmentation of uracil molecules and pure and nano-hydrated uracil clusters by (12)C(4+) ion impact is investigated. This work focuses on the fragmentation behavior of complex systems and the effect of the environment.

PHOTOSENSITIZED DIMERIZATION OF URACIL

Photochemistry and Photobiology, 1972
Abstract— The four isomeric dimers of uracil were isolated from photochemical reactions which were sensitized by acetone. Product analyses, made on the basis of the chemical properties of the compounds, showed that the h, h dimers predominate. Infrared and mass spectra for the dimers are here presented as well as nuclear magnetic resonance data.

Hydrogen-bonding effects on infrared spectra from anharmonic computations: uracil-water complexes and uracil dimers.

Journal of Physical Chemistry A, 2015
Hydrogen-bonding interactions lead to significant changes in the infrared (IR) spectrum, like frequency shifts of the order of magnitude of hundreds of cm(-1) and increases of IR intensity for bands related to vibrational modes of functional groups ...

Accurate DNA Assembly and Genome Engineering with Optimized Uracil Excision Cloning.

ACS Synthetic Biology, 2015
Simple and reliable DNA editing by uracil excision (a.k.a. USER cloning) has been described by several research groups, but the optimal design of cohesive DNA ends for multigene assembly remains elusive.

ALTERATION OF URACIL-DNA GLYCOSYLASE ACTIVITY BY URACIL DIMERS IN DNA

Photochemistry and Photobiology, 1981
— The effects of UV irradiation on double-stranded PBS-2 phage DNA, which contains uracil in place of thymine, were studied. Irradiation by 254 nm light, or by 313 nm light in the presence of the triplet sensitizer acetophenone, resulted in production of uracil-containing pyrimidine photodimers. DNA chain breaks were also produced under both conditions.

A colorimetric and smartphone readable method for uracil-DNA glycosylase detection based on the target-triggered formation of G-quadruplex.

In Analysis, 2015
A simple, visible and smartphone readable strategy for the sensitive detection of uracil-DNA glycosylase (UDG) activity has been developed. This is based on the UDG-catalyzed removal of uracil bases, which induces the formation of a G-quadruplex-cofactor
