TLC–Densitometric Analysis of Selected 5-Nitroimidazoles

open access: yesProcesses, 2023
Metronidazole, ornidazole, tinidazole, and secnidazole are 5-nitroimidazoles. The purpose of this work was to propose a new economical TLC–densitometric method to evaluate the chemical stability of metronidazole, secnidazole, ornidazole, and tinidazole under stress conditions. A forced degradation study was performed on silica gel and aqueous solutions

Coupling of C-nitro-NH-azoles with arylboronic acids. A route to N-aryl-C-nitroazoles

open access: yesBeilstein Journal of Organic Chemistry, 2013
A method for the synthesis of N-aryl-C-nitroazoles is presented. A coupling reaction between variously substituted arylboronic acids and 3(5)-nitro-1H-pyrazole catalyzed by copper salt has been carried out in methanol in the presence of sodium hydroxide ...

Synthesis of New Active Sulfones in the 5-Nitroimidazole Series

open access: yesMolecules, 2002
We describe here the preparation of new 5-nitroimidazoles which are known to have an efficacy against metronidazole-susceptible and -resistant Giarda, Trichomonas, and Entamoeba spp. The multi-step synthesis uses electron transfer methodology.

208 Identification of Trichomonas vaginalis 5-nitroimidazole resistance targets to inform future drug development

open access: yesJournal of Clinical and Translational Science, 2022
OBJECTIVES/GOALS: 5-nitroimidazoles are the only FDA-approved medications for T. vaginalis treatment. Resistance has been observed in 5-10% of cases, but may be rising. We aimed to delineate mechanisms of resistance in isolates of T.

Optimising hypoxia PET imaging and its applications in guiding targeted radiation therapy for non‐small cell lung cancer: a scoping review

open access: yesJournal of Medical Radiation Sciences, Volume 72, Issue 1, Page 106-118, March 2025.
This review article reports that quantification of hypoxic volumes using PET in the pre‐radiation therapy setting is of prognostic value and indicative of treatment response in non‐small cell lung cancer. Abstract Introduction Non‐small cell lung cancer (NSCLC) is the leading cause of cancer‐related death. Definitive treatment includes chemotherapy and
