Toward pyridine-fused selenium-containing antioxidants.

چکیده
Photolysis of the thiohydroximate ester derivative 21 of 2-carboethoxy-2-(2- (benzylseleno)pyridin-3-yl)tridecylcarboxylic acid (20) affords 2-dodecyl-2- carboethoxy-2,3-dihydroselenolo[2,3-b]pyridine (22) in 89% yield in a process presumably involving intramolecular homolytic substitution by a tertiary alkyl radical at selenium with loss of a benzyl radical. Work toward extending this methodology to the preparation of pyridine-fused selenium analogues of antioxidants is described.

Expedient synthesis of a phenanthro-imidazo-pyridine fused heteropolynuclear framework via CDC coupling: a new class of luminophores.
We herein report the design and synthesis of a group of fused phenanthro-imidazo[1,2-a]pyridine derivatives as a new class of luminescent materials through a Pd(ii) catalyzed intramolecular CDC (cross dehydrogenative coupling) reaction. This method thus unlocked a convenient & expedient way for the synthesis of a new molecular framework containing π-extended fused heteropolycycles. The heteropo...
متن کاملThe antioxidants dilemma: are they potentially immunosuppressants and carcinogens?
INTRODUCTION Antioxidants and a large number of natural supplements were introduced in recent decades (Lu et al., 2013). It has been hypothesized that antioxidant consumption might reverse oxidative stress which decreases the adverse effects elicited as outcomes of oxidative stress including inflammation, carcinogenesis, and atherosclerosis (Ghorbanihaghjo et al., 2012; Bjelakovic et al., 2014)...
متن کاملDiselenolodiselenole: a selenium containing fused heterocycle for conjugated systems.
The synthesis of new conjugated building blocks, diselenolodiselenole (C4Se4) derivatives, is described for the first time. The structural and optoelectronic properties of C4Se4-derivatives are tuned by varying end-capping aromatic substituents. In cyclic voltammetry, all C4Se4-derivatives show two reversible oxidation peaks.
متن کاملMetal- and Semimetal-Containing Inhibitors of Thioredoxin Reductase as Anticancer Agents.
The mammalian thioredoxin reductases (TrxRs) are a family of selenium-containing pyridine nucleotide disulfide oxidoreductases playing a central role in cellular redox homeostasis and signaling pathways. Recently, these selenoproteins have emerged as promising therapeutic targets for anticancer drug development, often being overexpressed in tumor cells and contributing to drug resistance. Herei...
متن کاملPyridine-2,6-bis(thiocarboxylic acid) produced by Pseudomonas stutzeri KC reduces and precipitates selenium and tellurium oxyanions.
The siderophore of Pseudomonas stutzeri KC, pyridine-2,6-bis(thiocarboxylic acid) (pdtc), is shown to detoxify selenium and tellurium oxyanions in bacterial cultures. A mechanism for pdtc's detoxification of tellurite and selenite is proposed. The mechanism is based upon determination using mass spectrometry and energy-dispersive X-ray spectrometry of the chemical structures of compounds formed...
