Synthesis of modified oligonucleotides in which the specific cytidine nucleoside analogues linked at 2'-OH position via a carbamate bond with an amino ethyl derivative of dansyl fluorophore is reported. For the multiple labeling of oligonucleotides, a strategy involving prelabeling at

The synthesis of oligonucleotides containing 2'-deoxy-2'-fluoro-4'-thioarabinonucleotides is described. 2'-Deoxy-2'-fluoro-5-methyl-4'-thioarabinouridine (4'S-FMAU) was incorporated into 18-mer antisense oligonucleotides (AONs). 4'S-FMAU adopts a predominantly northern sugar conformation. Oligonucleotides containing 4'S-FMAU, unlike those containing FMAU, were unable to elicit E. coli or human RNase

LNA guanine and 2,6-diaminopurine (D) phosphoramidites have been synthesized as building blocks for antisense oligonucleotides (ON). The effects of incorporating LNA D into ON were investigated. As expected, LNA D containing ON showed increased affinity towards complementary DNA (Delta Tm

A simple chemical method for the synthesis of 1,2-diacyl-sn-glycerophosphatidylserine (PS), with the same fatty acid composition in the sn-1 and sn-2 glycerol positions as egg phosphatidylcholine (PC), is described. PS synthesis was carried out by a phosphite-triester approach, using 2-cyanoethyl-N,N,N',N'-tetraisopropylphosphorodiamidite

Hexofuranosyl nucleosides are considered as conformationally restricted acyclic nucleosides using a furanose ring to link the diol backbone to the nucleobase. The phosphoramidite of 1-(2,3-dideoxy-beta-D-erythro-hexofuranosyl)thymine was synthesized from thymidine with formation of a new stereocentre at C-5' and the nucleoside
