  Stereospecific Synthesis of Oligonucleotides Containing Crotonaldehyde Adducts of Deoxyguanosine

  摘要：

  Crotonaldehyde reacts with DNA to form two diastereomeric 1,N-2 cyclic adducts of deoxyguanosine. A synthesis of the two diastereomeric deoxynucleosides has been achieved by reaction of mixed diastereomers of 4-amino-1,2-pentanediol with 2-fluoro-O-6-(trimethylsilylethyl)-deoxyinosine. The resulting N-2-(1-methyl-3,4-dihydroxybutyl)-deoxyguanosine was treated with NaIO4, cleaving the vicinal diol to the aldehyde. Spontaneous cyclization gave the two diastereomers of the crotonaldehyde-adducted nucleoside that were readily separated by HPLC. The absolute configurations were assigned by an enantiospecific synthesis of one diastereomer from (S)-3-aminobutanoic acid. The synthetic strategy has been extended to preparation of a site-specifically adducted oligonucleotide by reaction of the mixed diastereomers of 4-amino-1,2-pentanediol with an 8-mer oligonucleotide containing 2-fluoro-O-6-(trimethylsilylethyl)-deoxyinosine. The diastereomeric oligonucleotides were separated by HPLC and absolute configurations of the adducts were established by enzymatic digestion to the adducted nucleosides.

  A confounding problem with studying the effects of environmental exposure to contaminants in wild populations is that analytical techniques are invasive, particularly where the physiological effects of the toxin are assessed. In this study, a metabonomic approach to investigate the biochemical effects of chronic oral exposure to environmentally realistic doses of CdCl2 (low, 8 mg/kg; high, 40 mg/kg) is presented. H-1 NMR spectra of urine from exposed animals were analyzed using pattern recognition methods to identify biomarkers for a 94 day exposure period. Creatinuria and both increased excretion and complexation of citrate was detected after 19 days of exposure in both exposure groups. This was accompanied by a decrease in plasma Ca2+/Mg2+ ratio in blood plasma after 94 days. Post mortem, magic angle spinning (MAS) H-1 NMR spectroscopy was used alongside conventional analytical techniques to investigate intact tissue directly. According to atomic absorption sectroscopy, kidney tissue accumulated 26.8 +/- 2.5 mug of Cd2+/g dry wt (low) and 75.9 +/- 4.3 mug of Cd2+/g dry wt (high). Using high-resolution MAS H-1 NMR spectroscopy altered lipid content was detected in kidneys from animals exposed to Cd2+. However, unlike acute exposure, no testicular damage was evident. This systemic approach to metabolism demonstrated the different physiological effects of chronic subacute compared with an acute exposure to Cd2+.
