The impact of a number of synthetic nucleoside derivatives on the growth and survival of cultured human ovarian tumor cells (line SKOV-3) and normal human lung fibroblasts was investigated. It was shown that the dialdehyde derivatives of uridine, 1--D-eritrofuranozyl uracil and 3-O--D-ribofuranosyl-2-deoxythymidine, in contrast to their unoxidized counterparts, exert marked toxic effect on SKOV-3 cells. Cultured human fibroblasts were less susceptible to the damaging effect of the dialdehyde nucleosides. The dialdehyde derivative of 1--D-eritrofuranozyl uracil demonstrated greatest differences in the cytotoxic effect on these cultures: inhibition of tumor SKOV-3 cells growth on 50% or more was achieved at the concentrations of this compound ten times lower than in the case of normal fibroblasts.
