3'-Amino-2',3'-dideoxycytidine (8) was directly synthesized from 2'-deoxycytidine, 2',3'-Dideoxy-3'-(N-acyl-L-phenylalanylamino)cytidines (acyl =butoxycarbonyl (9a), acetyl (9b), benzoyl (9c), and α-hexanoyl (9d)) were synthesized as chymotrypsin-activated prodrugs of 8. This N-protection was required for activation by chymotrypsin to 8. In vitro, compound 8 showed high cytotoxic activity against P388 cells, but the prodrugs 9a-d were ineffective. In vitro, however, these prodrugs showed much higher activity than 8 in mice bearing P388 cells.
A facile procedure for the reduction of azido nucleosides to amines using polymer bound triphenylphosphine

A very convenient reduction of azido nucleosides to amines under mild conditions using polystyryl diphenylphosphine resin is described. The method requires only a filtration and evaporation process for product isolation.

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.
