The CuAAC 'click' reaction was used to couple alkyne-functionalized lanthanide-DOTA complexes to a range of fluorescent antennae. Screening of the antenna components was aided by comparison of the luminescent output of the resultant sensors using data normalized to account for reaction conversion as assessed by IR. A maximum 82-fold enhanced signal:background luminescence output was achieved us...
Somatostatin receptor positron emission tomography-computed tomography (PET/CT) with 68Ga-1,4,7,10-tetraazacyclododecane-1,4,7,10-tetraacetic acid (DOTA) peptides have become an indispensable part of disease assessment in patients with neuroendocrine tumors and forms the basis of personalized therapy with peptide receptor-based radionuclide therapy. With growing utilization of PET/CT in develop...
Two bicyclic compounds containing Arg-Gly-Asp (RGD) motifs (RGDf and RGD) were synthesized by cyclizing the peptide sequence across the macrocyclic ring of DOTA via two non-adjacent carboxylate pendent arms. The Lu(3+) or Cu(2+) complexes of these compounds, c(DOTA-RGDf) and c(DOTA-RGD), showed a metal dependent affinity towards integrin α(v)β(3)in vitro and the (177)Lu(3+) or (64)Cu(2+) labell...
Complications associated with the vascular access for hemodialysis represent one of the most important causes of morbidity among patients with renal replacement therapy. Early detection of arteriovenous fistula (AVF) dysfunction is of great interest. We present the case of a 70 year old woman who underwent 111In-oxine-labeled-platelet scintigraphy to evaluate thrombogenicity at 3 weeks and 3 mo...
Antisense oligonucleotides (ASOs) are recognized therapeutic agents for the modulation of specific genes at the post-transcriptional level. Similar to any medical drugs, there are opportunities to improve their efficacy and safety. Here we develop a short DNA/RNA heteroduplex oligonucleotide (HDO) with a structure different from double-stranded RNA used for short interfering RNA and single-stra...
introduction: due to the interesting pharmacological properties of radiolabeled metal oxine derivatives such as cell internalization, tumor avidity and antiproteosome activity, 111in-tris[8-hydroxy-2-methylquinoline] (111in-hmq) was developed in this study. methods: 111in-hmq was prepared using 111incl3 and 8-hydroxy-2-methylquinoline (hmq) for 60 min at 100°c (radiochemical purity: >99% itlc, ...
objectives: the aim of this research was the development of 111in-labeled porphyrins as possible radiopharmaceuticals for the imaging of tumors. methods: ligands, 5, 10, 15, 20-tetrakis (3, 5-dihydroxyphenyl) porphyrin) (tdhpp), 5, 10, 15, 20-tetrakis (4-hydroxyphenyl) porphyrin (thpp) and 5, 10, 15, 20-tetrakis (3,4-dimethoxyphenyl) porphyrin) (tdmpp) were labeled with 111incl3 (produced from ...
Pretargeted radioimmunotherapy (PRIT) using an anti-CD45 antibody (Ab)-streptavidin (SA) conjugate and DOTA-biotin labeled with β-emitting radionuclides has been explored as a strategy to decrease relapse and toxicity. α-emitting radionuclides exhibit high cytotoxicity coupled with a short path length, potentially increasing the therapeutic index and making them an attractive alternative to β-e...
PURPOSE The aim of this study is to synthesize and evaluate (68)Ga-labeled Lissamine Rhodamine B (LRB) as a new radiotracer for imaging MDA-MB-231 and MCF-7 cells induced tumor mice by positron emission tomography (PET). METHODS Firstly, we performed the radio synthesis and microPET imaging of (68)Ga(DOTA-LRB) in athymic nude mice bearing MDA-MB-231 and MCF-7 human breast cancer xenografts. A...
