Cell experiment [1]:

Cell lines

Human colon carcinoma cell line HT-29

Preparation method

The solubility of this compound in DMSO is >10 mM. General tips for obtaining a higher concentration: Please warm the tube at 37℃ for 10 minutes and/or shake it in the ultrasonic bath for a while. Stock solution can be stored below -20℃ for several months.

Reaction Conditions

0.01 ~ 10 μM; 7 days


In human colon carcinoma cell line HT-29, Fluorouracil suppressed cell viability, with the IC50 value of 2.5 μM.

Animal experiment [2]:

Animal models

C56B1/6 mice bearing Colon 38 tumor

Dosage form

100 mg/kg; i.p.; weekly


Fluorouracil (100mg/kg) significantly suppressed tumor growth of murine colon carcinoma Colon 38 with tumor-doubling time (TD), growth-delay factor (GDF), and T/C of 26.5 days, 4.4, and 14%.

Other notes

Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal.

Fluorouracil (Adrucil), a heterocyclic aromatic organic compound, is a potent anticancer agent widely used for the treatment of solid tumors, including breast cancer, ovarian cancer, head and neck cancer, and colon cancer. As an analogue of uracil, fluorouracil has a fluorine atom replacing the hydrogen atom at the C-5 position. Due to its similar chemical structure to DNA and RNA, fluorouracil and metabolites exert strong anticancer activities through incorporation into DNA and RNA and inhibition of thymidylate synthase (TS). Fluorouracil is metabolized into fluorodeoxyuridine monophosphate (FdUMP), which inhibits TS by forming a stable complex with it and subsequently suppresses the production of deoxythymidine monophosphate (dTMP), an essential enzyme involved in DNA replication and repair, leading to cytotoxicity and cell death.
