A series of 2',3'-unsaturated and 3'-substituted 2',3'-dideoxynucleoside analogues of purines and pyrimidines have been synthesized and evaluated for their inhibitory activity against human immunodeficiency virus (HIV).The 2',3'-unsaturated analogues of 2',3'-dideoxycytidine (ddeCyd) and 2',3'-dideoxythymidine (ddeThd), 3'-azido-2',3'-dideoxythymidine (AzddThd), 3'-fluoro-2',3'-dideoxythymidine, 2',3'-dideoxycytidine (ddCyd), and 2',3'-dideoxyadenosine (ddAdo) emerged as the most potent inhibitors of HIV-induced cytopathogenicity in the human T lymphocyte cell lines ATH8 and MT4.In ATH8 cells ddCyd, ddeCyd, and ddAdo had the highest therapeutic index whereas in MT4 cells AzddThd, ddThd, ddCyd, and ddAdo were the most selective.Derivatives from ddThd in which the substituent group was linked to the 3'-carbon atom via a thio, sulfonyl, or oxygen bridge were far less inhibitory to HIV than was AzddThd.

Various new 5-substituted 3'-azido- and 3'-amino derivatives of 2'-deoxyuridine and 2'-deoxycytidine have been synthesized and biologically evaluated.Among these compounds, 3'-amino-2',3'-dideoxy-5-fluorouridine (3), 3'-amino-2',3'-dideoxycytidine (7a), and 3'-amino-2',3'-dideoxy-5-fluorocytidine (7c) were found to be the most active against murine L1210 and sarcoma 180 neoplastic cells in vitro, with an ED50 of 15 and 1 μM, 0.7 and 4 μM, and 10 and 1 μM, respectively.The 3'-azido derivatives, 2 and 6c, were less active in comparison with their 3'-amino counterparts.In addition, the 5-fluoro-3'-amino nucleosides, 3 and 7c, were tested against L1210 leukemia bearing CDF1 mice.Our preliminary findings indicate that compound 7c (6 * 200 mg/kg) was as active as the positive control, 5-fluorouracil (6 * 20 mg/kg), yielding a T/C * 100 of 146 and 129, respectively.However, 3 was found to be inactive in this experiment.
