| 5-Fluorouracil Usage And Synthesis |
| Antimetabolite |
5-fluorouracil is short for fluorouracil, and is pyrimidine antimetabolites, 5-fluorouracil as fluorouracil for pyrimidine antimetabolites, is currently clinically commonly used a chemotherapy drug, having effect on proliferation, can prevent the thymine formation, inhibition of DNA biosynthesis, thereby inhibiting the growth of cancer cells. Clinically, it is used to treat gastrointestinal tumors, such as stomach cancer, colon cancer, liver cancer and so on. In breast cancer, ovarian cancer, lung cancer, bladder cancer, cervical cancer, pancreatic cancer and so on are also effective. The Swiss production of skin cancer treatment ointment containing 5% of the goods, mainly used for actinic keratoses and senile keratosis, precancerous dermatitis, single and multiple shallow table basal cell carcinoma, radioactive skin lesion of carcinoma and superficial basal cell carcinoma. 5-fluorouracil first changes for 5-Fluoro 2 deoxy urea pyrimidine nucleotides in vivo and inhibition of thymidylate synthase, blocking the transformation of urea pyrimidine deoxyribonucleotide thymidine, which affects DNA biosynthesis. At the same time, it can be incorporation into RNA by blocking urea ethyl pyridine and whey acid was incorporated into the RNA to direct inhibition of RNA synthesis. This medicine is mainly in the liver metabolism, most of the decomposed into carbon dioxide discharged from breathing, rarely excreted from urine. After oral, absorption is different; vein after administration, concentrations in plasma quickly drop in two hours; static note within 30 minutes can arrive in cerebrospinal fluid (CSF) and maintain for 3 hours; continuous intravenous infusion toxicity is lighter than intravenous injection; vein to the drug's effect is compared with oral high. Toxicity of 5-fluorouracil on the proliferation is greater than non proliferating cells, but no obvious cell cycle specificity. Resistance to 5-FU can increase essential activity of enzyme missing or thymidylate synthetase activity. The above information is edited by the Chemicalbook Hayan. |
| Pharmacokinetics |
Due to the instability of the absorption of 5-fluorouracil, the conventional the oral (in Europe can be obtained from oral preparation). General intravenous administration, We can also take transarterial Administration in order to directly reach the tumor (e.g. liver metastasis through hepatic artery) and injected directly into the body cavity infiltration liquid (such as ovarian cancer). Intravenous injection plasma half-life is 7.5~10 minutes, after 3 hours the drug in the plasma has not check did not change. Intracellular drug levels are last much longer. Fluorouracil in the liver is used for metabolism; 60~80% in 8~12 hours as a respiratory carbon dioxide discharge and 15% in 6 hours technical unchanged from the urine discharge. The drug can enter into the exudate and cerebrospinal fluid (CSF). It has existed determination method for plasma fluorouracil. |
| Indications |
It is clinical for breast cancer, digestive tract cancer, ovarian cancer and primary bronchogenic lung adenocarcinoma adjuvant chemotherapy and palliative care; is also in the treatment of malignant hydatidiform mole, choriocarcinoma, serous cancer of effusion in bladder cancer and head and neck malignant tumor and liver cancer chemotherapy drugs. Dermatological topical containing 5% 5-fluorouracil ointment is used in the treatment of actinic keratosis, actinic cheilitis, Bowen's disease, erythroplasia of Queyrat, Bowenoid papulosis, condyloma acuminatum, vitiligo, lichen amyloidosis, disseminated superficial porokeratosis, warts, flat warts, psoriasis, color of dry skin disease, superficial basal cell epithelioma table etc.; intralesional injection in the treatment of keratoacanthoma keloid. |
| Drug interaction | Before using this drug, first it is used methotrexate, 5-fluorouracil nucleotide formation is increased by increasing the content of intracellular phosphoribosyl pyrophosphate. Allopurinol can change the role of fluorouracil. Its metabolites, oxypurinol, can inhibit orotate phosphoribosyl transferase and thus reduce the toxicity and may improve the therapeutic index. Increase in thymidine and other nucleoside combination of fluorouracil and RNA and thymidine by dihydropyrimidine dehydrogenase can delay fluorouracil decomposition. However, the drug combination did not significantly improve the clinical effect so far. |
| Adverse reactions and precautions |
The main toxic effect of fluorouracil is involving the gastrointestinal tract and blood cell generation system. Anorexia, nausea and vomiting were common. Stomatitis, pharyngo esophageal inflammation and diarrhea are withdrawal indication, otherwise there will be serious oropharyngeal and intestinal ulcers. Intravenous administration of gastrointestinal toxicity is often limiting dose. On the contrary, huge doses of intravenous injection, white cell reduction is the dose limiting toxicity. Low white cell counts often appear in medication for the first time after 7 to 14 days. Thrombocytopenia is not too obvious, appeared in 7~17. Monitoring of blood cell count is necessary. Other adverse reactions are hair loss, dermatitis and pigment calm. There were acute and chronic conjunctivitis. Reversible cerebellar ataxia occurs in 1% of patients, possibly is related to the dose, occur at any time of the treatment process (often a few months later). After Cerebellar signs in the withdrawal can be last for a few of weeks. Myocardial ischemia occasionally appeared in the 5-FU intravenous drip. The drug in animals is caused by abnormal and may be carcinogenic. Damage to the liver function of patients (e.g. extensive liver metastasis) fluorouracil should be reduced; The nutritional status of patients with poor medication should be cautious. Using daily intermittent intravenous drip for 4~5d, can greatly reduce the toxic effects of blood. However, the results of clinical research mean rapid injection or intravenous drip method in the treatment of superiority. Long term intravenous drip infusion can be accompanied by pain, erythema and skin scaling of hand-foot comprehensive syndrome. This medicine to FDA pregnancy category D. |
| Fluorofur | Fluorofur is fluorine urea pyrimidine derivatives, and effect is similar with fluorouracil, but chemotherapy index double higher than fluorouracil and toxicity is only the 1/4 to 1/6 of fluorouracil. It is suitable for gastrointestinal cancer and breast cancer. There are oral, intravenous and anal suppository three formulations. |
| Chemical property | It is white or white crystalline powder. Mp is 282-283ºC (decomposition), 0.1 mol/L hydrochloric acid solution has maximum absorption at 265nm wavelength.
