Dynamics and efficiency of electron injection and transport in DNA using pyrenecarboxamide as an electron donor and 5-bromouracil as an electron acceptor.

Pierre Daublain et al.

The journal of physical chemistry. B, 114(45), 14265-14272 (2010-02-04)

The photophysical and photochemical behavior of a series of hairpin-forming DNA conjugates possessing a 5'-tethered pyrenecarboxamide chromophore and one or two bromouracil bases has been investigated. Quenching of the pyrene fluorescence and transient absorption spectra characteristic of the pyrene cation

Fragmentation patterns of core-ionized thymine and 5-bromouracil.

E Itälä et al.

The Journal of chemical physics, 133(15), 154316-154316 (2010-10-26)

Photofragmentation of thymine and 5-bromouracil into cation and neutral fragments following the core ionization by soft x-rays using photoelectron-photoion-photoion coincidence technique has been studied. The fragment ion mass spectra were recorded in coincidence with the C 1s photoelectron spectra. In

Low-energy electron-induced damage in a trinucleotide containing 5-bromouracil.

Zejun Li et al.

The journal of physical chemistry. B, 115(46), 13668-13673 (2011-09-10)

The reaction of low-energy electrons (LEEs; 10 eV) with 5'-TpXpT-3' (TXT), where X is uracil (U), thymine (T), and 5-bromouracil (5BrU), was examined by HPLC-UV analysis. The presence of 5BrU increased total damage by >50%. The radiation products of T5BrUT

The distance between donor and acceptor affects the proportion of C1' and C2' oxidation products of DNA in a BrU-containing excess electron transfer system.

Ryu Tashiro et al.

Journal of the American Chemical Society, 132(41), 14361-14363 (2010-09-30)

We have investigated the products of (Br)U in excess electron transfer and have demonstrated that in DNA the proportion of products changes with the distance between the donor and acceptor. On the basis of a labeling experiment using H(2)(18)O, we

Photoreactivities of 5-bromouracil-containing RNAs.

Hironobu Morinaga et al.

Bioorganic & medicinal chemistry, 21(2), 466-469 (2012-12-26)

5-Bromouracil ((Br)U) was incorporated into three types of synthetic RNA and the products of the photoirradiated (Br)U-containing RNAs were investigated using HPLC and MS analysis. The photoirradiation of r(GCA(Br)UGC)(2) and r(CGAA(Br)UUGC)/r(GCAAUUCG) in A-form RNA produced the corresponding 2'-keto adenosine ((keto)A)
