Introduction: Porphyrins are interesting derivatives with low toxicity, tumor avidity and rapid wash-out suggested as potential radiopharmaceuticals in radiolabeled form. In this work we report, synthesis, radiolabeling, quality control, stability, partition coefficient determination and biodistribution studies of 153Sm-5,10,15,20-tetrakis(4-methoxyphenyl) porphyrin (153Sm-4-MPP) in ...
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...
a series of 3-hydroxypyridin-4-one derivatives (hpos) were synthesized and their partition coefficient values (k part ) were determined. the cytotoxic effects of these iron chelators against hela cancer cells were also evaluated. the ic 50 of hpos was determined using mtt assay. among these ligands, compound 4e (k part =5.02) with an ic 50 of 30 µm and 4f (k part =0.1) with an ic 50 of 700 µm s...
Introduction: In continuation of recent development of possible C-X-C chemokine receptor type 4 (CXCR4) imaging agents, we report the development of a possible CXCR4 targeted therapy agent. Methods: [153Sm]labeled 1,1′-[1,4-phenylenebis(methylene)] bis-1,4,8,11-tetraazacyclo -tetradecane ([153Sm]-AMD3100) was prepared using [153Sm]SmCl3 and AMD-3100 ...
