The beta-D-(2S,5R)- and alpha-D-(2S,5S)-1,3-oxathiolanylpyrimidine and -purine nucleosides with natural nucleoside configuration were synthesized and evaluated against HIV-1 in human peripheral blood mononuclear (PBM) cells. The key intermediate 14, which was utilized for the synthesis of various nucleosides, was synthesized from

Three triple-helical hairpin DNAs with substitution of 5-bromocytosine for cytosine in different strands have been investigated by molecular mechanics and Raman spectroscopy. The stability of the three substituted triplexes were compared with the corresponding unsubstituted triplex DNA by the molecular

Three triplex DNAs containing 5-bromocytosine[BrC] were studied by vibrational spectroscopy and molecular modelling. Firstly, three oligodeoxypyrimidines of 5'-(TC)3-T4-(BrCT)3 [CBrC], 5'-(TBrC)3-T4-(CT)3 [BrCC] and 5'-(TBrC)3-T4-(BrCT)3 [BrCBrC] were synthesized and then reacted with an oligodeoxypurine of 5'-(AG)3 at pH=4.5 in phosphate buffer respectively
