Technetium-99m complexes with steroid-2-aminooxyethyliminodiacetic acid conjugates.
Conjugates of 2-aminooxyethyliminodiacetic acid with estrone, testosterone, epiandrosterone, 17-alpha-hydroxy-progesterone and progesterone were synthesized and their complexes with Tc-99m were successfully prepared in good yields, which indicated the agent to be promising for metal-labeling of biomolecules and related substances containing one or more carbonyl groups. The biodistribution and s...
متن کاملSynthesis and experimental study of norfloxacin labeled with technecium-99m as a potential agent for infection imaging
Introduction: Differentiation between infection and sterile inflammation is one of the most difficult medical problems and is relevant in many clinical situations. Scintigraphy with radiolabeled antibiotics, еspecially labeled fluoroquinolones, is a promising tool for diagnosing bacterial inflammation. We have attempted to synthesize 99mTc-norfloxacin and studied its properties in ex...
متن کاملAn improved synthesis and preliminary biodistribution study of a Technetium-99m-labeled 2-amino-2-deoxy(thioacetyl)-D-glucose complex ([99mTc]-TA-DG) as a tumor imaging agent
Introduction: This report describes the synthesis of 2-Amino-2-deoxy(S-benzoylthioacetyl)-D-glucose (S-Bz-TA-DG), radiolabeled with [99mTc(CO)3(OH2)3]+ complex with a procedure including deprotection of the benzoyl group, characterization by HPLC using a C18 reverse phase column and preliminary biodistribution study in normal ...
متن کاملNovel [99mTcN]2+ labeled EGFR inhibitors as potential radiotracers for single photon emission computed tomography (SPECT) tumor imaging.
The epidermal growth factor receptor (EGFR) is overexpressed in many cancers, including breast, ovarian, endometrial and non-small cell lung cancer. An EGFR-specific imaging agent could facilitate clinical evaluation of primary tumors or metastases. To achieve this goal, 4-(2-aminoethylamino)-6,7-dimethoxyquinazoline (ADMQ) was synthesized based on a 4-aminoquinazoline core and then conjugated ...
متن کاملNUCLEAR PHARMACY Rapid Quality Control of Technetium-99m-2-Methoxy Isobutyl Isonitrile (Technetium-99m-Sestamibi)
Objective: Technetium-99m-sestamibi (-1"'Tc-MIBI) is a radiopharmaceutical imaging agent useful for assessing myocardial perfusion. We present a simple, rapid and accurate SepPak® method to confirm the radiochemical purity of "'Tc-MIBI. Methods: Technetium-99m-MIBI preparations of high (>95%), intermediate (83-90%) and low (25-43%) radiochemical purity were evaluated by the recommended thinlaye...
