Description
Sources: http://www.ncbi.nlm.nih.gov/pubmed/6230419

Doxifluridine is a 5-fluorouracil prodrug that is being tested for the treatment of cancer. The cleavage into 5-fluorouracil occurs enzymatically via a nucleoside phosphorylase. Thus, doxifluridine is not active by itself and its antitumor activity is related to its metabolic conversion into 5-fluorouracil. Doxifluridine has neurotoxic adverse effects.

In Vitro Use Guide

The cytotoxicity of Doxifluridine was determined in several cultured human tumor lines including tumors of the breast (47-DN, MCF-7), the colon (HCT-8), and the pancreas (Coto-357), as well as an osteosarcoma (MG-63) and a leukemia (HL-60). In vitro clonogenic assays were used to measure cytotoxicity following a 3hr drug exposure. Doxifluridine was less potent than was 5-fluorouracil or 5-fluoro-2'-deoxyuridine in all cells examined, exhibiting its best activity against the 47-DN [concentration that prevented 50% clonal growth compared to untreated control (LD50) = 32 uM] and MCF-7 (LD50= 35 uM) breast carcinomas and MG63 osteosarcoma (LD50 = 41 uM). Intermediate activity was observed against HCT-8 (LD50 = 200 uM)and Colo-357 (LD50 = 150 uM) gastrointestinal tumors. Doxifluridine had very poor activity against the HL-60 leukemia (LD50 = 470 uM).
