from our investigations the following compounds have emerged as particularly potent and selective inhibitors of hiv replication : sulphated polysaccharides ( i.e . heparin , dextran sulphate , pentosan polysulphate ) , dideoxynucleoside analogues such as the 3'-azido-and 3'-fluoro-substituted 2',3'-dideoxyribosides of both purines ( i.e . guanine , 2,6-diaminopurine ) and pyrimidines ( i.e . uracil , thymine ) , and the 9- ( 2-phosphonylmethoxyethyl ) derivatives of adenine , 2-monoaminopurine and 2,6-diaminopurine .
