Carbostyril derivatives as antenna molecules for luminescent lanthanide chelates.
Luminescent lanthanide complexes consisting of a lanthanide-binding chelate and organic-based antenna molecule have unusual emission properties, including millisecond excited state lifetimes and sharply spiked spectra, compared to standard organic fluorophores. We have previously used carbostyril (cs124, 7-amino-4-methyl-2(1H)-quinolinone) as an antenna molecule (Li and Selvin, J. Am. Chem. Soc...
متن کاملSynthesis of multidentate ligands with amido or amino donor groups for the preparation of rhenium and technetium radiopharmaceuticals
A new method to prepare novel semi-rigid multidentate ligands containing nitrogen atom, to coordinate with rhenium and technetium, was established. The method was based on formylation of substituted anilines, followed by Mannich reaction with glycine and paraformaldehyde. The method was very promising to design ligands of various molecular structures (L1-L5) to coordinate with rhenium metal ion...
متن کاملFluorine- and rhenium-containing geldanamycin derivatives as leads for the development of molecular probes for imaging Hsp90.
Heat shock protein 90 (Hsp90) is an ATP-dependent molecular chaperone responsible for protein quality control in cells. Hsp90 has been shown to be overexpressed in many human cancers. This has prompted extensive research on Hsp90 inhibitors as novel anticancer agents and, more recently, the development of molecular probes for imaging Hsp90 expression in vivo. This work describes the development...
متن کاملDibromidooxido[(Z)-N′-(propan-2-ylidene)benzohydrazidato](triphenylphosphane)rhenium(V)
The asymmetric unit of the title neutral rhenium(V) coordination compound, [ReBr(2)(C(10)H(11)N(2)O)O(C(18)H(15)P)], contains two mol-ecules. In each of the two molecules the metal atom is octa-hedrally coordinated, the bromido ligands being cis-orientated. The chelate ligand is present in its imine-tautomeric form. In the crystal, C-H⋯Br contacts connect the mol-ecules into chains along [101]....
متن کاملPhosphonated chelates for nuclear imaging.
A series of bis-, tris- and tetra-phosphonated pyridine ligands is presented. In view of their potential use as chelates for radiopharmaceutical applications, the physico-chemical properties of the ligands and of their Co(II), Ni(II), Cu(II), and Zn(II) complexes were studied by means of potentiometry and UV-Vis absorption spectroscopy. The pKa values of the ligands and of the complexes, as wel...
