title: Synthesis of 5-alkynylated d4T analogues as potential HIV-1 reverse transcriptase inhibitors.
abstract: A series of 2',3'-didehydro-2',3'-dideoxynucleosides substituted with an alkynylhydroxy- (6, 7, 12 and 13) and alkynylamino- (20) groups at the C-5 position were synthesized. All these five target modified nucleosides were tested for anti-human immunodeficiency virus type 1 activity in CEM-SS and MT-4 cells and unfortunately displayed no improvement in antiviral activity.
