Molecular recognition of sugars by lanthanide (III) complexes of a conjugate of N, N-bis[2-[bis[2-(1, 1-dimethylethoxy)-2-oxoethyl]amino]ethyl]glycine and phenylboronic acid.


A novel conjugate of phenylboronic acid and an Ln(DTPA) derivative, in which the central acetate pendant arm was replaced by the methylamide of L-lysine, was synthesized and characterized. The results of a fit of variable (17)O NMR data and a (1)H NMRD profile show that the water residence lifetime of the Gd(III) complex (150 ns) is shorter than that of the… (More)
