Stereocontrolled Syntheses of All Four Stereoisomeric 1,N2-Deoxyguanosine Adducts of the Lipid Peroxidation Product trans-4-Hydroxynonenal
摘要:
[GRAPHICS]trans-4-Hydroxynonenal (4-HNE) is a unique product from the peroxidation of omega -6 polyunsaturated fatty acids. The major reaction of racemic 4-HNE with DNA is with deoxyguanosine to give four stereoisomeric exocyclic propano adducts. The stereospecific syntheses of these four adducts has been achieved at the nucleoside level. The synthetic approach is amenable to the synthesis of structurally defined oilgonucleotides containing these endogenous genotoxins.

is a major peroxidation product of omega-6 polyunsaturated fatty acids. The reaction of HNE with DNA gives fourdiastereomeric 1,N(2)-gamma-hydroxypropano adducts of deoxyguanosine; background levels of these adducts have been detected in animal tissue. Stereospecificsyntheses of these four adducts at the nucleoside level have been accomplished. In addition, a versatile strategy for their site-specific
