Synthetic ways to introduce functional groups (CO2Me, CO2H, OCH2CO2H, OCH2C≡CH, CH2OH, CH2Cl, CH2N3) into the pyridine ring of pyridine-containing azacrown compounds are described. These groups were introduced at position-4 of the pyridine ring, while keeping the macrocyclic carboxylate groups available for metal chelation. The derivatives were obtained by macrocyclization reaction of 4-substituted
The introduction of copper chelates into peptide mimetics creates the Src SH2 binding ligands and paramagnetic complexes suitable for EPR studies of peptide protein interactions. The dipicolinic acid was attached to SH2 domain targeting fragments by two different linkers. (C) 2004 Elsevier Ltd. All rights reserved.
