Formaldehyde-mediated modification of natural deoxyguanosine with amines: one-pot cyclization as a molecular model for genotoxicity
摘要:
Stable cross-linked adducts, 3-(2-deoxy-beta -D-ribofuranosyl)-7-phenyl-5,6,7,8-tetrahydro[1,3,5]triazino[1,2-a]purin-10(3H)-one and 7-butyl-3-(2-deoxy-beta -D-ribofuranosyl)-5,6,7,8-tetrahydro[1,3,5]triazino[1,2-a]purin-10(3H)-one, that formed chemically from natural deoxyguanosine and aniline or buthyl amine in the presence of formaldehyde were identified. This reaction appears to be a general reaction of deoxyguanosine and primary amines, and it may be a model of DNA modification with carcinogenic aromatic amines without metabolic activation, if formaldehyde is present.
