Efficient preparation of 2-nitroimidazole nucleosides as precursors for hypoxia PET tracers

چکیده
ABSTRACT 2-Deoxy-D-ribose was converted to α/β-mixtures of methyl 3-O-acetyl- and methyl 3-O-benzoyl-2-deoxy-5-(p-toluenesulfonyl)-D-ribofuranosides. These were reacted with boron trichloride to generate ribofuranosyl chlorides, which afforded precursors for tracers to image tumor hypoxia on substitution with salts of 2-nitroimidazole. The anomeric ratio of the nucleosides was delicately influenced by the reaction conditions. GRAPHICAL ABSTRACT

Preparation of Nucleosides Derived from 2-Nitroimidazole and d-Arabinose, d-Ribose, and d-Galactose by the Vorbrüggen Method and Their Conversion to Potential Precursors for Tracers To Image Hypoxia
2-Nitroimidazole was silylated using hexaethyldisilazane and then reacted with 1-O-acetyl derivatives of D-arabinose, D-ribose, and D-galactose in acetonitrile at mild temperatures (-20 °C to rt), catalyzed by triethylsilyl triflate (Vorbrüggen conditions). The α-anomer was formed in the former case and the β-anomers in the latter two cases (highly) selectively. When D-arabinose and D-ribose we...
متن کاملThe application of unconventional PET tracers in nuclear medicine
The production and application of PET tracers has been a unique step in the progress of nuclear medicine in last two decades. The most important PET tracers include F-18, C-11 and N-13 radioisotopes and many nuclear medicine centers throughout the globe are using them. However some new tracers are under their way to the mass administration, currently being in th...

Positron emission tomography (PET) imaging of tumor hypoxia provides valuable information for cancer treatment planning. Two types of PET tracers, nitroimidazole compounds and [62,64Cu] copper-diacetyl-bis[N(4)-methylthio- semicarbazone] (Cu-ATSM), have been used for imaging hypoxic tumors. High accumulation of these tracers in tumors was shown to predict poor prognosis. Both similar and differ...
متن کامل2-Nitroimidazole as Potential Nanoprobe in Hypoxia Imaging by MRI/PET
2-Nitroimidazole is radiosensitizer and serves as imaging contrast agent by 19Fand 31P MR methods. Despite the success of mesonidazole and SR-4554 compounds, very little is known of its hepato-cytotoxicity if it can be potential hypoxia imaging marker and non-toxic drug. Authors established the low oxygen, low energy metabolic ratio and gluconeogenesis in nitroimidazole induced hepatocytes and ...
متن کاملPET radiopharmaceuticals for imaging of tumor hypoxia: a review of the evidence.
Hypoxia is a pathological condition arising in living tissues when oxygen supply does not adequately cover the cellular metabolic demand. Detection of this phenomenon in tumors is of the utmost clinical relevance because tumor aggressiveness, metastatic spread, failure to achieve tumor control, increased rate of recurrence, and ultimate poor outcome are all associated with hypoxia. Consequently...
