NITROIMIDAZOLES VIII [I]. SYNTHESES, ANTIBACTERIAL AND ANTIFUNGAL ACTIVITIES OF 2-PYRIDYL-NITROIMIDAZOLES [PDF]
Starting from 2-(2-pyridyl) imidazole a series of substituted imidazoles (2-5) were prepared. From the reaction of 2-(3-pyridyl) -4-(or 5) nitroimidazole (15) with dimethyl sulfate in alkaline medium 1-methyl-2-(3- pyridy1)-4-nitroimidazole (6,)w as ...

Nitroimidazoles XIII. Synthesis of Substituted (1-Methyl-5-Nitro-2-Imidazolyl) Isoxazoles [PDF]
The beta0diketone derivatives of nitroimidazole were synthesized from the reaction of magnesium salt of beta-ketoaccids 3 with imidazolide 4. The raction of beta-diketones with hydroxylamine hydrochloride afforded either the isoxazoles or the 5-hydroxyl ...

In vitro and in vivo pharmacodynamics of three novel antileishmanial lead series
Objectives: Three new chemical series (bicyclic nitroimidazoles, aminopyrazoles and oxaboroles) were selected by Drugs for Neglected Diseases initiative as potential new drug leads for leishmaniasis. Pharmacodynamics studies included both in vitro and in

MICROBIAL OXIDATION OF AMINOIMIDAZOLES TO NITROIMIDAZOLES
The structural requirements for the microbial transformation of 2-aminoimidazoles to 2-nitroimidazoles by Streptomyces strain LE/3342 have been investigated. Substrates carrying an alkyl group in position 4 (or 5) were oxidized, the efficiency decreasing with the increase of the length of the chain.

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