High Performance Liquid Chromatography:Article Title: Formation of a fluorescent adduct in the reaction of 2'-deoxyadenosine with a malonaldehyde-acetaldehyde condensation product. Article Snippet: Malonaldehyde (malondialdehyde, MDA) was reacted with 2′-deoxyadenosine in buffered aqueous solution.. HPLC analyses of the reaction mixtures showed that, besides the two previously characterized N6-propenal (M1dA) and N6-oxazocinyl (M3dA) adenine adducts, a third compound eluting at longer retention time was formed.. The compound generated a strong peak in the chromatogram recorded by a fluorescence detector. Article Title: New nucleoside analogs from 2-amino-9-(beta-D-ribofuranosyl)purine. Article Snippet: Four novel derivatives of 2-amino-9-(β- -ribofuranosyl)purine (1) were synthesised and fully characterised.. When 1 was reacted with chloroacetaldehyde (a), 2-chloropropanal (b), bromomalonaldehyde (c) and a mixture of chloroacetaldehyde malonaldehyde (d), 3-(β- -ribofuranosyl)-imidazo-[1,2a]purine (2), 3-(β- -ribofuranosyl)5-methylimidazo-[1,2a]purine (3), 3-(β- -ribofuranosyl)-5-formylimidazo-[1,2a]purine (4) and 9-(β- -ribofuranosyl)2-(3,5-diformyl-4-methyl-1,4-dihydro-1-pyridyl)purine (5) were formed, respectively.. The products were isolated, purified by chromatography and characterised by MS, complete NMR assignment as well as fluorescence and UV spectroscopy. Article Title: Reaction of the potent bacterial mutagen 3-chloro-4-(dichloromethyl)-5-hydroxy-2(5H)-furanone (MX) with 2'-deoxyadenosine and calf thymus DNA: identification of fluorescent propenoformyl derivatives. Article Snippet: The potent bacterial mutagen and drinking water disinfection byproduct 3-chloro-4(dichloromethyl)-5-hydroxy-2(5H)-furanone (MX) was reacted with 2′-deoxyadenosine and calf thymus DNA in aqueous solutions at neutral conditions.. HPLC analyses of the 2′-deoxyadenosine reaction mixtures showed that two previously unidentified products were formed.. The products were isolated by preparative C18 chromatography, and their structures were characterized by UV absorbance, fluorescence emission, 1H and 13C NMR spectroscopy, and mass spectrometry. Article Title: Identification of a novel fluorescent adduct formed in the reaction of malonaldehyde with adenosine. Article Snippet: Malonaldehyde was reacted with adenosine in aqueous solution at acidic conditions and the reaction mixtures were analysed by HPLC.. Four major product peaks were observed in the chromatogram recorded by the UV detector at 320nm.. Two of the peaks could be deduced to the previously characterised malonaldehyde–adenosine reaction product 9-(b-D-ribofuranosyl)-6-(5,7-diformyl-2H-3,6-dihydro-2,6-methano-1,3-oxazocin-3-yl)purine (M3A) and to the ribose analogue of the 2 0-deoxy adduct 9-(2 0-deoxy-b-D-ribofuranosyl)-6-(3,5-diformyl-4-methyl-1,4-dihydro-1-pyridyl)purine (M2AA-dA). Article Title: Identification of adducts formed in reactions of 2-deoxyadenosine and calf thymus DNA with the bacterial mutagen 3-chloro-4-(chloromethyl)-5-hydroxy-2(5H)-furanone. Article Snippet: 3-Chloro-4-(chloromethyl)-5-hydroxy-2(5H)-furanone (CMCF) is a strong direct acting bacterial mutagen found in chlorine-disinfected drinking water.. We studied the reaction of CMCF with 2′-deoxyadenosine in buffered aqueous solutions and found that three main adducts were formed.. The adducts were isolated and purified by C18 column chromatography and HPLC, and characterized on the basis of their UV absorbance, fluorescence emission, 1H and 13C NMR spectroscopic, and mass spectrometric features.
