Green methods for the determination of nitrite in water samples based on a novel diazo coupling reaction

open access: yesGreen Processing and Synthesis, 2017
Green, sensitive and selective spectrophotometric methods were developed for the determination of nitrite in water samples. The methods (A, B and C) are based on the reduction of 5-nitroimidazoles; metronidazole (MTL), secnidazole (SCL) and tinidazole ...

Metabolism of nitro drugs metronidazole and nitazoxanide in Giardia lamblia: characterization of a novel nitroreductase (GlNR2) [PDF]

open access: yes, 2017
Objectives The protozoan parasite Giardia lamblia causes giardiasis, a persistent diarrhoea. Nitro drugs such as the nitroimidazole metronidazole and the nitrothiazolide nitazoxanide are used for the treatment of giardiasis.

Nitroimidazole scaffold: a potential panacea for infectious diseases—a review

open access: yesDiscover Chemistry
Nitroimidazoles are five-membered heterocyclic ring systems in which the ‘’nitro’’ group is appended to either carbon 2 (benznidazole), 4 (pretomanid) or 5 (fexinidazole) of the imidazole ring.

Iridium complex, a phosphorescent light-emitting diode material, serves as a novel chemical probe for imaging hypoxic tumor tissues [PDF]

open access: yes, 2007
Iridium complex, a promising organic light-emitting diode for next generation television displays, emits phosphorescence. Phosphorescence is quenched by oxygen. We used this oxygen-quenching feature for imaging tumor hypoxia.
