Cancer pharmacology is often markedly toxic and must be precisely dosed in order to reach the therapeutic bioavailability under strict control. Transport properties are important tools process of interpretation fine-tuning pharmaceutical applications, notably for drugs that have a long record use met their limits bioavailability. 5–Fluorouracil (5-FU) one most used antineoplastic agents since i...
5-Fluorouracil (5-FU) is a commonly used chemotherapeutic agent. However, its neurotoxicity is rare and not well recognized. We report a case of 5-FU neurotoxicity with organic brain syndrome and progression to multifocal leukoencephalopathy in a 44-year-old male patient having malignant gastrointestinal stromal tumor. 5-FU-induced neurotoxicity should, therefore, be considered as an important ...
5-FormylH4folate is administered clinically under the name Leucovorin in association with the antineoplastic agent 5-fluorouracil (5-FU) to enhance the cytotoxic effects of 5-FU. The combination has been shown to be superior to 5-FU alone in the treatment of patients with metastatic colorectal carcinoma. Methenyltetrahydrofolate synthetase (MTHFS) catalyzes the transformation of 5-formyl-tetrah...
The mechanism of action of fluorouracil (5-FU) and the oral fluoropyrimidines and the importance of biochemical modulation and inhibition of dihydropyrimidine dehydrogenase for oral application of the prodrugs of 5-FU are discussed. The regulation of thymidylate synthase, as well as its roles as a target for antineoplastic activity and in drug resistance, are also mentioned. The more downstream...
1-Hexylcarbamoyl-5-fluorouracil (HCFU) was found to be hydrolyzed to 5-fluorouracil (5-FU) depending on temperature. In this study, the antitumor effects of HCFU with hyperthermia were studied on Ehrlich ascites in tumor-bearing CD-1 mice and Nakahara-Fukuoka sarcoma cells. Concurrently, the change of 5-FU concentration in the Ehrlich tumor was also observed. In vivo, Ehrlich cells were transpl...
TWEAK/Fn14 signaling mediates gastric cancer cell resistance to 5-fluorouracil via NF-κB activation.
Chemoresistance is one of the most serious problems in the treatment of cancer. In the present study, we show that Fn14 promotes resistance to 5-fluorouracil (5-FU) in gastric cancer (GC). We found that 5-FU treatment upregulated Fn14 expression in various cancer cell lines, including GC cell lines, and that knockdown of Fn14 using shRNA accelerated 5-FU sensitivity. In contrast, Fn14 overexpre...
5-fluorouracil (5-FU) is a key chemotherapeutic agent in the treatment of many gastrointestinal tract adenocarcinomas. Despite its proven therapeutic efficacy, 5-FU also possesses several undesired cardiac toxicities, including coronary vasospasm, coronary thrombosis, cardiomyopathy, and sudden cardiac death. This review addresses the incidence, mechanisms of action, clinical presentation, risk...
