Doxifluridine is a fluoropyrimidine derivative and oral prodrug of the antineoplastic agent 5-fluorouracil (5-FU) with antitumor activity. Doxifluridine, designed to circumvent the rapid degradation of 5-FU by dihydropyrimidine dehydrogenase in the gut wall, is converted into 5-FU in the presence of pyrimidine nucleoside phosphorylase. 5-FU interferes with DNA synthesis and subsequent cell division by reducing normal thymidine production and interferes with RNA transcription by competing with uridine triphosphate for incorporation into the RNA strand.

4 Pharmacology and Biochemistry
4.1 MeSH Pharmacological Classification

Antimetabolites, Antineoplastic

Antimetabolites that are useful in cancer chemotherapy. (See all compounds classified as Antimetabolites, Antineoplastic.)


Appetite Stimulants

Agents that are used to stimulate appetite. These drugs are frequently used to treat anorexia associated with cancer and AIDS. (See all compounds classified as Appetite Stimulants.)


Immunosuppressive Agents

Agents that suppress immune function by one of several mechanisms of action. Classical cytotoxic immunosuppressants act by inhibiting DNA synthesis. Others may act through activation of T-CELLS or by inhibiting the activation of HELPER CELLS. While immunosuppression has been brought about in the past primarily to prevent rejection of transplanted organs, new applications involving mediation of the effects of INTERLEUKINS and other CYTOKINES are emerging. (See all compounds classified as Immunosuppressive Agents.)
