Synthetic Approaches to Nuclease-Resistant, Nonnatural Dinucleotides of Anti-Hiv Integrase Interest
摘要:
New, nonnatural dinucleotide 5'-monophosphates with a surrogate isonucleoside component of L-related stereochemistry, have been synthesized. Structures of the target compounds were confirmed by multinuclear NMR spectra (H-1, C-13, P-31, COSY), UV hypochromicity, FAB HRMS data and X-ray crystallography. These compounds are totally resistant to cleavage by 3'- and 5'-exonucleases. Dinucleotides of this study with a terminal L-isonucleoside component showed remarkable selectivity for inhibition of the strand transfer step of HIV-1 integrase. To the best of our knowledge, these compounds represent only the second example of this type of selectivity of inhibition of the strand transfer step.

New, non-natural dinucleotide 5'-monophosphates, with a surrogate isonucleoside component Of L-related stereochemistry at the 'terminal' position, have been synthesized. Structures of 2a-c were confirmed by multinuclear NMR spectra (H-1, C-13, (31)p, COSY), UV hypochromicity and FAB HRMS data. These compounds are totally resistant to cleavage by 3'- and 5'-exonucleases. The dinucleotides showed remarkable selectivity for inhibition of the strand transfer step of HIV-1 integrase. To the best of our knowledge, these compounds represent only the second example of selective strand transfer inhibitors of HIV integrase. (C) 2004 Elsevier Ltd. All rights reserved.
