abstract：:5'-Deoxy-5-fluorouridine (5'-dFUrd; Roche 21-9738) is a recently synthesized antineoplastic agent with therapeutic potential. The sensitivity of Ehrlich ascites tumor cells in CF-1 mice to 5'-dFUrd, as well as to 5-fluorouridine, was established. 5'-dFUrd was a more effective antitumor agent and was less toxic over a ...
