Kanagasundaram, Thines;Laube, Markus;Wodtke, Johanna;Kramer, Carsten Sven;Stadlbauer, Sven;Pietzsch, Jens;Kopka, Klaus research published 《 Radiolabeled Silicon-Rhodamines as Bimodal PET/SPECT-NIR Imaging Agents》, the research content is summarized as follows. Radiolabeled fluorescent dyes are decisive for bimodal imaging as well as highly in demand for nuclear- and optical imaging. Silicon-rhodamines (SiRs) show unique near-IR (NIR) optical properties, large quantum yields and extinction coefficients as well as high photostability. Here, we describe the synthesis, characterization and radiolabeling of novel NIR absorbing and emitting fluorophores from the silicon-rhodamine family for use in optical imaging (OI) combined with positron emission tomog. (PET) or single photon emission computed tomog. (SPECT), resp. The presented photostable SiRs were characterized using NMR-, UV-Vis-NIR-spectroscopy and mass spectrometry. Moreover, the radiolabeling conditions using fluorine-18 or iodine-123 were extensively explored. After optimization, the radiofluorinated NIR imaging agents were obtained with radiochem. conversions (RCC) up to 70% and isolated radiochem. yields (RCY) up to 54% at molar activities of g.t. 70 GBq/μmol. Radioiodination delivered RCCs over 92% and allowed to isolate the 123I-labeled product in RCY of 54% at a molar activity of g.t. 7.6 TBq/μmol. The radiofluorinated SiRs exhibit in vitro stabilities g.t. 70% after two hours in human serum. The first described radiolabeled SiRs are a promising step toward their further development as multimodal PET/SPECT-NIR imaging agents for planning and subsequent imaging-guided oncol. surgery.
244205-40-1, 2-Bromophenylboronic Acid is used as an inhibitor of the hormone sensitive lipase.
2-Bromophenylboronic acid, also known as 2-Bromophenylboronic acid, is a useful research compound. Its molecular formula is C6H6BBrO2 and its molecular weight is 200.83 g/mol. The purity is usually 95%.
2-Bromophenylboronic acid is a glucose monitoring agent that has a ruthenium complex with an acidic environment. The nitro group and the amines are in close proximity to the boron center, and this proximity leads to a high nucleophilic character of the molecule. This reactivity allows 2-bromophenylboronic acid to be used as a fluorescence probe for acidic environments. 2-Bromophenylboronic acid also inhibits secretase enzymes, which are involved in Alzheimer’s disease and other neurodegenerative disorders. It is an inhibitor of γ-secretase, which is responsible for cleaving the amyloid precursor protein (APP), and it has shown efficacy against biphenyl, an anticancer drug that binds to benzodiazepine receptors. 2-Bromophenylboronic acid is also an enantiopure compound because all four substituents are different from each other., Related Products of 244205-40-1
