title: Synthesis and biological activity of O-alkyl-3-N-aminoacyloxymethyl-5-fluoro-2'-deoxyuridine derivatives.
abstract: In an attempt to improve the effectiveness of action of 5-fluoro-2'-deoxyuridine (FUdR), various kinds of O-alkylated water-soluble analogues were synthesized. Antitumor activities against sarcoma 180 (solid) were also evaluated. Some compounds exhibited potent activities. In particular, 3'-O-p-chlorobenzyl-3-N-aminoacyloxy-methylester derivatives were effective over a very wide range of dose and gave extremely large therapeutic ratios compared with known 5-fluorouracil (5-FU) derivations.
