Synthesis and Characterization of DNA Containing O6-Carboxymethylguanine
摘要:
O-6-Carboxymethylguanine was formed in DNA treated with N-nitrosoglycocholic acid and believed to be implicated in human gastrointestinal and colorectal tumour. An efficient method is presented here for synthesis of oligodeoxynucleotides containing O-6-carboxymethylguanine at pre-determined positions. The synthetic protocol also allows for production of oligomers containing O-6-aminocarbonylmethylguanine. These guanine-modified oligomers have been fully characterized and could provide a useful tool for biological studies of these modified bases. (C) 2000 Elsevier Science Ltd. All rights reserved.
