Metabolism of drugs. LXXX. The metabolic fate of nitrofuran derivatives. 3. Studies on enzymes in small intestinal mucosa of rat catalyzing degradation of nitrofuran derivatives.
The enzymes responsible for the degradation of nitrofuran derivatives in rat small intestinal mucosa were examined in vitro.As a result,it was suggested that the initial reactions in the degradation of 2-(2-furyl)-3-(5-nitro-2-furyl)acrylamide(AF-2) and 5-nitro-2-furfural semicarbazone(nitrofurazone)are mainly catalyzed by xanthine oxidase , while that of 2-amino-5-[2-(5-nitro-2-fury1)-1-(2-fur...
متن کاملInduction of unscheduled DNA synthesis in primary culture of dog, rat, and mouse urothelial cells by arylamine and nitrofuran derivatives.
The induction of unscheduled DNA synthesis in primary cultures of urothelial cells from rats, mice, and dogs by nitrofurans and arylamines and their derivatives was examined. Electron microscopy of the culture from rat cells showed the characteristics of epithelial cells. The cultured cells were exposed to the test chemicals in a serum-free medium containing 10 mM hydroxyurea and [3H]thymidine ...
متن کاملEffiecient Synthesis of tetrazoloquinoxaline derivatives
Displacement reaction of 2,3-dichloroquinoxaline with secondary amines in boiling ethanol afforded it`s mono aminoquinoxaline derivatives. Further reaction of the latter compounds with sodium azide in warm dimethylsulfoxide achieved a group of 4-amino tetrazolo[1,5-a]quinoxaline derivatives. 1HNMR spectra of these compounds are discussed.
متن کاملTrypanosoma cruzi: effect and mode of action of nitroimidazole and nitrofuran derivatives.
With the aim of determining the actual target(s) of nitro-group bearing compounds considered as possible leads for the development of drugs against Chagas' disease, we studied in parallel nitrofurans and nitroimidazoles. We investigated nine representative compounds for the following properties: efficacy on different Trypanosoma cruzi strains, redox cyclers, inhibition of respiration, productio...
متن کاملThe carcinogenic activity of some 5-nitrofuran derivatives in the rat.
Three 5-nitrofuran derivatives showed carcinogenic activity when fed to female Holtzman rats at levels of 0.1 to 0.3% in a commercial diet for up to 44.5 weeks, while 2 other 5-nitrofuran derivatives and 5,5-diphenylhydantoin were inactive. Formic acid 2-[4-(5-nitro-2-furyl)-2-thiazolyl]hydrazide induced benign and malignant tumors of the mammary glands, adenomas or adenocarcinomas of the kidne...
