Nucleoside dialdehydes were obtained by periodate oxidation of adenosine, cytidine, guanosine, uridine or 6-azauridine in the presence of Dowex (1x8; CH3COO-). Reductive alkylation of daunorubicin with these dialdehydes in the presence of NaBH3CN produced a series of 3'-deamino-3'-(4-morpholino)daunorubicin or 13-(R,S)-dihydrodaunorubicin derivatives, the latter being mixtures of two diastereomers at 13-C atom. The morpholino-daunorubicin derivatives containing nucleic base moieties are less cytotoxic than cyanomorpholino-daunorubicin, morpholino-daunorubicin and even than the parent antibiotic.

Nearly 30 synthetic nucleosides were tested with human recombinant poly(ADP-ribose) polymerase 1 as potential inhibitors of this enzyme. The most active compounds were some disaccharide analogues of thymidine: 3-O-beta-D-ribofuranosyl-5-iodo-dUrd (2d; IC50 = 45 mu M), 3-O-beta-D-ribofuranosyl-2-deoxythymidine (2e; IC50 = 38M), and 3-O-beta-D-ribofuranosyl-2-deoxythymidine oxidized (4; IC50 = 25 mu M). These compounds also reduced H2O2-induced synthesis of poly(ADP-ribose) in cultured human ovarian carcinoma (SKOV-3) cells in a dose-dependent manner. Furthermore, compounds 2d or 2e until a concentration of 1mM did not affect growth of SKOV-3 cells, whereas dialdehyde compound 4, as well as thymidine, exhibited a significant cytotoxicity.
