Synthesis and radioiodination of a nido-1,2-carboranyl derivative of 2-nitroimidazole

open access: yes, 1994
The synthesis of a nido-carboranyl congener of misonidazole, 1-(3′-nido-carboranyl-2′-hydroxy)propyl-2-nitroimidazole, has been carried out. Alternative methods of preparations were conducted to optimize the chemical yield, with a five step synthesis ...

Influence of manipulating hypoxia in solid tumors on the radiation dose-rate effect in vivo, with reference to that in the quiescent cell population. [PDF]

open access: yes, 2010
PURPOSE: The aim of this study was to clarify the effect of manipulating intratumor hypoxia on radiosensitivity under reduced dose-rate (RDR) irradiation. MATERIALS AND METHODS: Tumor-bearing mice were continuously given 5-bromo-2'-deoxyuridine (BrdU) to

Chemical and biological studies of the radiosensitizer misonidazole

open access: yes, 1981
Misonidazole (Ro 07-0582) is a nitroheterocyclic drug which sensitizes hypoxic (oxygen-deficient) cells to the lethal action of ionising radiation. Tumours contain radioresistant hypoxic cells which may limit the usefulness of radiotherapy as a modality ...

Splanchnic tissues undergo hypoxic stress during whole body hyperthermia

open access: yes, 1999
Exposure of conscious animals to environmental heat stress increases portal venous radical content. The nature of the observed heat stress-inducible radical molecules suggests that hyperthermia produces cellular hypoxic stress in liver and intestine.

Prospective trial incorporating pre-/mid-treatment [18F]-misonidazole positron emission tomography for head-and-neck cancer patients undergoing concurrent chemoradiotherapy

open access: yes, 2009
To report the results from a prospective study of a series of locoregionally advanced head-and-neck cancer patients treated with platinum-based chemotherapy and intensity-modulated radiotherapy and to discuss the findings of their pre-/mid-treatment [18F]

Misonidazole binding in murine liver tissue: a marker for cellular hypoxia in vivo

open access: yes, 1989
The hepatic microcirculation is believed to cause variable cellular oxygenation within the organ. In this study a marker of cellular hypoxia was used to demonstrate liver oxygen tension gradients in vivo.

Data_Sheet_1_Radiation Damage Mechanisms of Chemotherapeutically Active Nitroimidazole Derived Compounds.pdf

open access: yes, 2019
Photoionization mass spectrometry, photoelectron-photoion coincidence spectroscopic technique, and computational methods have been combined to investigate the fragmentation of two nitroimidazole derived compounds: the metronidazole and misonidazole ...

Radiation-dose dependence of the enhancement of DNA-damage in cells treated with the hypoxic radiosensitizer ak-2123, a 3-nitrotriazole derivative

open access: yes, 1994
The radiosensitizing effect of AK-2123, a 3-nitrotriazole, and of misonidazole, a 2-nitroimidazole, was studied on hypoxically irradiated Chinese hamster cells (V79-379A) with DNA damage as end-point.
