Biological Activity

5-fluorouracil (5-FU) is a chemotherapy compound that is a pyrimidine analog which is used in the treatment of cancer. 5-fluorouracil (5-FU) works through noncompetitive inhibition of thymidylate synthase. Fluorouracil IC50 values were observed across the National Cancer Institute NCI60 panel of human tumor cell lines, which exhibit a mean IC50 of 17.6 μM, with a range of 1~501 μM.

In vivo, 5-fluorouracil (23 mg/kg, 3 times/week) for 14 days, induces accelerated gastrointestinal transit associated with acute intestinal inflammation at day 3 after the start of treatment, which may have led to persistent changes in the ENS observed after days 7 and 14 of treatment contributing to delayed gastrointestinal transit and colonic dysmotility.

For example, to modify the dose of resveratrol used for a mouse (22.4 mg/kg) to a dose based on the BSA for a rat, multiply 22.4 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for resveratrol of 11.2 mg/kg.
