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
The present invention relates to 5-fluorouracil derivatives represented by formula (i), pharmaceutical compositions comprising said derivative and their use in the treatment of cancer as well as a process for preparing the 5-fluorouracil derivative represented by formula (I).
