[ 1 ] - Preparation and Biodistribution of [67Ga]-labeled- oxytocin for SPECT purposes
Background: Oxytocin (OT) is a paracrine hormone with various biological activities and many sex organs in both sexes, as well as many tumor cells have shown to have related receptors. In this study the development of a receptor imaging tracer for possible tumor imaging has been described. Materials and Methods: OT was successively labeled with [67Ga]-gallium chloride after conjugation with fre...
[ 2 ] - Preparation and quality control of radiolabeled streptokinase for Thrombosis imaging
Background: In order to diagnose the site of thrombi, radiolabeled streptokinase can be prepared. The radiolabeled compound can be used in imaging of thrombi in many cardiovascular diseases. Materials and Methods: Streptokinase was successively labeled with [67Ga]-gallium chloride using cyclic DTPA-dianhydride. The conjugation with DTPA was optimized for concentration, time and temperature foll...
[ 3 ] - Development of [201Tl](III)oxinate complex for in vitro cell labeling
Background: The incorporation of thallium-201 into 8-hydroxyquinoline was targeted for cell labeling due to interesting physical properties and wide availability of this nuclide as a single photon emission computed tomography (SPECT) radionuclide. Materials and Methods: Thallium-201 (T1/2=3.04 d) in Tl+ form was converted to Tl3+ cation in presence of O3/6M HCl and di-isopropyl ether, controlle...
[ 4 ] - Production and evaluation of [67Ga]-DTPA-Rituximab
Background: In order to obtain an anti-CD20 conjugate to be used in future therapeutic studies with therapeutic radioisotopes, 67Ga-labeled antibody was prepared as a model of metal chelated immunoconjugate for preliminary dosimetric and biodistribution studies. Materials and Methods: Rituximab was labeled with [67Ga]-gallium chloride after residulation with freshly prepared cyclic DTP...
[ 5 ] - Preparation & Evaluation of [201Tl](III)-DTPA-HIgG for Inflammation Detection
Background: Radiolabeled polyclonal human immunoglubins are useful in the detection of inflammations. In this work a novel approach has been presented to use thallium-201 as a comlexed nuclide for the development of radioimmunoconjugates. Materials and Methods: Thallium-201 (T1/2=3.04 d) in Tl+ form was converted to Tl3+ cation in presence of O3 in 6M HCl, controlled by RTLC/gel electroph...
[ 6 ] - Radiosynthesis of [103Pd]-di-actyl-bis (N4-methylthiosemicarbazone): a potential therapeutic agent
Background: Due to interesting tumor imaging properties of bis-thiosemicarbazones, [103Pd]-di-acetyl-bis (N4-methylthiosemicarbazone) ([103Pd] ATSM2) was prepared according to the analogy of radio copper homologues. Materials and Methods: Palladium-103 (T1/2=16.96 d) was produced via the 103Rh (p,n) 103Pd nuclear reaction with proton energy 18 MeV. The final activity was eluted in form of Pd ...
[ 7 ] - Preparation of [64Cu] Pyruvaldehyde-bis (N4-methylthiosemicarbazone) complex as a PET and/or therapeutic radiopharmaceutical
Background: Copper-64 (T1/2=12.7 h) is an important radionuclide used both in PET imaging and therapy. [64Cu]-pyruvaldehyde-bis (N4-methylthiosemicarbazone) ([64Cu]-PTSM) is one of the most famous copper radiopharmaceuticals with unique specifications (suitable half life, stability, etc.). The wide range of 64Cu applications arouse great interest for its production. Materials and Methods: Cu-64...
[ 8 ] - Preparation, distribution, stability and tumor imaging properties of [62Zn] bleomycin complex in normal and tumor-bearing mice
Backgrounds: Bleomycin (BLM) has been labeled with radioisotopes and widely used in therapy and diagnosis. In this study BLM was labeled with [62Zn] zinc chloride for oncologic PET studies. Materials and methods: The complex was obtained at the pH=2 in normal saline at 90 ° C in 60 min. Radio-TLC showed an overall radiochemical yield of 95-97% (radiochemical purity > 97%). Stability of complex ...
