20090297447 | SYNTHESIS AND EVALUATION OF 18F-LABELLED-ALKYL-1-[(1R)-1-PHENYLETHYL]-1H-IMIDAZOLE-5-CARBOXYLATE AS A TRACER FOR THE QUANTIFICATION OF BETA-11-HYDROXYLASE ENZYME IN THE ADRENAL GLANDS - Radioactively labeled derivatives of (R)-3-(1-phenylethyl)-3H-imidazole-4-carboxylic acid esters and one-step methods for preparing these compounds are provided. The radioactively labelled compounds, and pharmaceutical acceptable salts and solvates are useful as radiopharmaceuticals, especially for use in Positron Emission Tomography (PET) for the diagnosis of adrenal cortical masses such as incidentaloma, adenoma, primary and metastatic cortical carcinoma. Associated kits and method for PET studies are also provided. | 12-03-2009 |

20100150835 | Synthesis of [18F] Fluoromethyl Benzene Using Benzyl Pentafluorobenzenesulfonate - The present invention discloses the reactivity of ponytail (“PT”) sulfonates as leaving groups in nucleophilic fluorination reactions. The results showed that using a pentafluorobenzenesulfonate precursor is a suitable leaving group for n. c. a. nucleophilic | 06-17-2010 |
20100228060 | PERFLUORO-ARYLIODONIUM SALTS IN NUCLEOPHILIC AROMATIC 18F-FLUORINATION - The present invention describes using fluorous chemistry in n.c.a. nucleophilic aromatic 18F-fluorination reactions by using perfluoro-aryliodonium salts as a precursor for aromatic nucleophilic substitution using a [18F] F-anion to displace a suitable leaving group from an electron deficient benzene ring. The results showed that using perfluoro-aryliodonium salts as a precursor is a suitable leaving group for n. c. a. nucleophilic aromatic 18F-fluorination in synthesis. The PT-precursor seems to be quite stable. In an attempt to purify the crude 18F-labeled product using fluorous solid phase extraction (F-SPE), the radio labeled impurities decreased significantly. Thus, it is possible to use this PT methodology to simplify and speed up purification methods. | 09-09-2010 |
