Fluorouracil inhibits thymidylate synthase during DNA synthesis, thereby halting cellular proliferation. 5-Fluorouracil cream 0.5% has been approved for 1-, 2-, and 4-week treatment periods. In one study, resolution of AK lesions was greatest in the

Fluorouracil (5-FU) is a synthetic pyrimidine agent that is commonly used for different solid malignancies such as adenocarcinomas and squamous cell cancers, including those of the gastrointestinal, urinary tract, breast, cervical, and neck cancers [9,10].
(PDF) Clinical Pharmacology of 5-Fluorouracil ResearchGate
AbstractTopical 5-fluorouracil has proved to be a useful therapy since its discovery nearly 50 years ago for the treatment of a range of cancers (e.g. skin, colorectal, breast) and dermatological conditions (e.g. cancerous and precancerous conditions such as actinic keratosis, benign tumors, nail psoriasis, mycosis fungoides, and porokeratoses).

The purpose of this work is to review the published studies on the mechanisms of action and resistance of 5-fluorouracil. The review is divided into three main sections: mechanisms of anti-tumor action, studies of the resistance to the drug, and procedures for the identification of new genes
Supplemental Information The Complex Mechanism of
Although 5-fluorouracil (5-FU) was first introduced in 1957, it remains one of the most important anticancer agents. In 5-FU, the hydrogen atom at the 5-position of uracil is replaced by a fluorine atom and the molecule was designed to occupy the active sites of enzyme targets, thereby blocking metabolism in malignant cells.
