The structure of 2',3'-didehydro-2',3'-dideoxynucleosides (d4Ns) was applied to design the novel bioisosteric 4'-seleno-d4Ns as potential inhibitors of human immunodeficiency virus reverse transcriptase (HIV RT). Conversion of 2',3'-dihydroxyl groups of 4'-selenoribofuranosyl pyrimidines into the olefin was accomplished by treatment of cyclic 2',3'-thiocarbonate with 1,3-dimethyl-2-phenyl-1,3,2-diazaphospholidine.

UI MeSH Term Description Entries
D009690 Nucleic Acid Conformation The spatial arrangement of the atoms of a nucleic acid or polynucleotide that results in its characteristic 3-dimensional shape. DNA Conformation,RNA Conformation,Conformation, DNA,Conformation, Nucleic Acid,Conformation, RNA,Conformations, DNA,Conformations, Nucleic Acid,Conformations, RNA,DNA Conformations,Nucleic Acid Conformations,RNA Conformations
D015224 Dideoxynucleosides Nucleosides that have two hydroxy groups removed from the sugar moiety. The majority of these compounds have broad-spectrum antiretroviral activity due to their action as antimetabolites. The nucleosides are phosphorylated intracellularly to their 5'-triphosphates and act as chain-terminating inhibitors of viral reverse transcription. 2',3'-Dideoxynucleosides,Dideoxyribonucleosides,ddNus,2',3' Dideoxynucleosides
