The synthesis of a series of cyclic and acyclic O‐2′,3′‐ketal derivatives of the cancerostatic 5‐fluorouridine (2a) is described. The novel compounds were characterized by 1H‐ and 13C‐NMR, and UV spectroscopy, as well as by elemental analyses. The lipophilicity values (log P, retention times in RP‐18 HPLC) of the cyclicketals were determined and related to the ring tensions as well as the acid stability

their insufficient penetration through cell membranes due to a high hydrophobicity. Thus, we have synthesized a series of selected nucleolipidderivatives of 5‐fluorouridine (5‐FUrd; 2a), carrying lipophilic moieties at N(3) and/or in the 2′,3′‐O‐position (i.e., 3a–7a and 3c), and tested their cytostatic/cytotoxicactivities using HT‐29 humancoloncarcinomacells, in comparison with, e.g., 5‐FU (1) and
