The aryl hydrocarbon receptor (AHR) is a ligand-inducible transcription factor that is best known because it mediates the actions of polycyclic and halogenated aromatic hydrocarbon environmental toxicants such as 3-methylcholanthrene and 2,3,7,8-tetrachlorodibenzo-p-dioxin. We report here the successful identification of an endogenous ligand for this receptor; approximately 20 microg was isolat...
Backgrond:Yersinia enterocolitica is zoonotic pathogen and one of important gastroenteritis agents. Some drug-resistant strains of this bacterium were discovered in the world. The use of new antibacterial compounds is one the best ways to deal with it. In this study, inhibitory effects of magnesium oxide nanoparticles, some heterocycles including thiazole, imidazolidine and tetrahydropyrimidin...
Utilization of benzoxazinone for synthesis quinazolinone derivatives with 3-heterocycle side chain. treatment of benzoxazinon 1 with cyano acetohydrazide or thionocarbohydrazide gave the quinazolinone derivatives 2 or 12. quinazolinone 2 has been utilized as synthon for new pyridinone, oxazet, thiazole, thiazolidinone and quinazolinone derivatives. Thiosemicarbazide and thiosemicarbazone deriv...
ses. Enzymatic determinations demonstrated, however, that the enzymes of the glycolytic pathway (up to the formation of triose phosphates) were present and active at 25 and 37 C. At 42 C, the mutant did not grow with any of the carbon sources used. At both 37 and 42 C, the mutant grew perfectly well with hexoses if yeast extract was present. The metabolite required for growth was thiamine or, s...
