英文摘要 | Four novel ester-amino ligands were synthesized by bis-acylation of octadecanyl, hexadecanyl, tetradecanyl and dedecanyl L-lysinate with ethylenediaminetetraacetic acid mono-anhydride (EDTA-MA), respectively. The corresponding neutral dimeric Gd(Ⅲ) complexes were gained by reacting these ligands with GdCl3·6H2O. All ligands and complexes were characterized by FTIR, ^1H NMR and elemental analysis. The longitunal relaxation time (T1) was measured, and their stability were investigated by competition with Ca^2+ and EDTA. The results indicate that the relaxivity of these netral binuclear Gd(Ⅲ)complexes are higher than that of Gd-DTPA |
