Design and synthesis of phosphorylated pyridine-based ligands for lanthanide complexation. Part 1
摘要:
Several new ligands constructed from a pyridine-ethynylnaphthalene platform have been engineered with a chelating pocket comprising bisdimethylaminocarboxylate/phosphonate or bisdimethylaminophosphonate units. Selective hydrolysis provides pockets with four to six anionic carboxylate or phosphate functions suitable for lanthanide complexation. Linkage at the opposite side of a flexible hanging arm either via a triple bond or through an amide tether offers the possibility of further use of these ligands for bio-conjugation. Protocols to link the dedicated pockets via hydrophilic flexible chain to Biotin are also detailed. (C) 2012 Elsevier Ltd. All rights reserved.
