Effects of Chloride, Bromide, and Iodide Upon Decomposition of Nucleosides Induced by Ultrasound in Neutral Solution
TLDR
A comparison with the results of the effects of halides on the reaction of nucleosides by a Fenton system suggested that only half of the nucleoside damage in the ultrasound-irradiated solution was caused by hydroxyl radicals formed from water by the sonication. Expand
Effects of nitrite and nitrate on DNA damage induced by ultraviolet light.
TLDR
Nitrite and nitrate may play a role in enhancing the genotoxic effects of UV light in humans by increasing the generation of nucleobases and malondialdehyde from DNA induced by sunlight. Expand
Formation of diazoate intermediate upon nitrous acid and nitric oxide treatment of 2'-deoxyadenosine.
TLDR
The results suggest that the diazoate can be formed in cellular nucleosides or DNA with biologically relevant dose of HNO(2) and NO. Expand
Reaction of 2'-deoxycytidine with peroxynitrite in the presence of ammonium bromide.
TLDR
It is suggested that in the presence of ammonium ion or amines, bromide ion interacts with peroxynitrous acid, which is a protonated form of perxynitrite, but not with hydroxyl radical or nitrogen dioxide generated by homolysis of peroxyspine acid, to form hypobromous acid. Expand
Reaction of 3',5'-di-O-acetyl-2'-deoxyguansoine with hypobromous acid.
TLDR
The results suggest that the products other than 8-bromoguanine may also have importance for mutagenesis by the reaction of HOBr with guanine residues in nucleotides and DNA. Expand
Effects of bromide upon reaction of nucleosides with hydrogen peroxide induced by ultraviolet light.
TLDR
The result of dose dependency of bromide suggests that dibromide radical anion is the reaction species to react only with 2'-deoxyguanosine, while the effect of deuterium oxide, an enhancer of singlet oxygen, was small. Expand
Effects of Halides on Reaction of Nucleosides with Ozone
TLDR
The results suggest that bromide may alter the mutation spectrum by O3 in humans using reversed-phase high-performance liquid chromatography with ultraviolet detection and indicates formation of hypobromous acid as the reactive agent. Expand
Reaction of acetaldehyde with 5-aminolevulinic acid via dihydropyrazine derivative.
TLDR
The results suggest that ALA may be useful as a scavenger for acetaldehyde and readministration of ALA 3 min prior to acetaldehyde injection supressed the toxicity of acetaldehyde in male mice. Expand
