Rapid kit-based 68Ga-labelling and PET imaging with THP-Tyr3-octreotate: a preliminary comparison with DOTA-Tyr3-octreotate
BACKGROUND Ge/(68)Ga generators provide an inexpensive source of a PET isotope to hospitals without cyclotron facilities. The development of new (68)Ga-based molecular imaging agents and subsequent clinical translation would be greatly facilitated by simplification of radiochemical syntheses. We report the properties of a tris(hydroxypyridinone) conjugate of the SSTR2-targeted peptide, Tyr(3)-o...
متن کاملDesign, Synthesis and Labeling of Tripeptide Derivatives with 99mTc as Hypoxia Imaging Agents
Background: Many diseases, including cancer, ischemia and tumors show degrees of tissue hypoxia.Therefore, it is useful to detect tissue hypoxia with compounds that can penetrate and remain in hypoxic cells in order to diagnose cancer at early stages. Peptides with low molecular weight, susceptible to redox environment, with easier penetration into tissues and low antigenic characteristics are ...
متن کاملEffects of broccoli extract on biodistribution and labeling blood components with 99mTc-GH.
PURPOSE People consume vegetables without the knowledge of the side effects of the biological and chemical contents and interactions between radiopharmaceuticals and herbal extract. To this end, current study is focused on the effects of broccoli extract on biodistribution of radiolabeled glucoheptonate ((99m)Tc-GH) and radiolabeling of blood components. METHODS GH was labeled with (99m)Tc. Q...

متن کاملA 99mTc-Labelled Tetrazine for Bioorthogonal Chemistry. Synthesis and Biodistribution Studies with Small Molecule trans-Cyclooctene Derivatives
A convenient strategy to radiolabel a hydrazinonicotonic acid (HYNIC)-derived tetrazine with 99mTc was developed, and its utility for creating probes to image bone metabolism and bacterial infection using both active and pretargeting strategies was demonstrated. The 99mTc-labelled HYNIC-tetrazine was synthesized in 75% yield and exhibited high stability in vitro and in vivo. A trans-cyclooctene...
