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 کاملThiol-reactive luminescent lanthanide chelates: part 2.
Luminescent lanthanide complexes have unusual spectroscopic characteristics, including millisecond excited-state lifetime and sharply spiked emission spectra. These characteristics make them valuable alternatives to conventional organic fluorescent probes in detection applications and for measuring nanometer-scale conformational changes in biomolecules via resonance energy transfer. Our group h...

متن کاملThiol-reactive luminescent chelates of terbium and europium.
Thiol-reactive lanthanide complexes have been synthesized that are luminescent when bound to terbium and/or europium. The complexes consist of a diethylenetriaminepentaacetate (DTPA) chelate covalently joined through one amide bond to a chromophore, carbostyril 124, and via a second amide bond to a maleimide, bromoacetamide, or pyridyldithio moiety. Site-specific attachment and characterization...
متن کاملSynthesis and optical properties of macrocyclic lanthanide(III) chelates as new reagents for luminescent biolabeling.
The convenient and efficient synthesis of two macrocyclic ligands (15- and 18-membered) based on a dipyrido-6,7,8,9-tetrahydrophenazine (dpqc) or 2,2':6',2''-terpyridine (tpy) heterocycle and a DTTA (diethylenetriaminetriacetic acid) skeleton is described. In these ligands the DTTA skeleton contains an additional extracyclic functionality (NH(2) group) suitable for covalent attachment to bioact...
