Abstract
![]()
Sialic acid recognition remains an
interesting and challenging
target in molecular receptor design. Herein, we report a series of
benzoboroxole-based receptors in which cationic hydrogen-bond donors
have been introduced and shown to promote multipoint sialic acid recognition.
One striking feature revealed by these receptors is that the carboxylate
sialic acid residue is the primary binding determinant for recognition
by benzoboroxole, in which the presence of charge-reinforced hydrogen
bonds results in enhanced selectivity for sialic acid over other carbohydrates
and a 4.5-fold increase in affinity. These findings open up wide possibilities
for benzoboroxole-based receptors use in life science research, biotechnology,
and diagnostics.

An Optimised Di-Boronate-ChemMatrix Affinity Chromatography to Trap Deoxyfructosylated Peptides as Biomarkers of Glycation. Molecules 2020; 25:E755.

Abstract
We report herein a novel ChemMatrix® Rink resin functionalised with two phenylboronate (PhB) moieties linked on the N-α and N-ε amino functions of a lysine residue to specifically capture deoxyfructosylated peptides, compared to differently glycosylated peptides in complex mixtures. The new PhB-Lys(PhB)-ChemMatrix® Rink resin allows for exploitation of the previously demonstrated ability of cis diols to form phenylboronic esters. The optimised capturing and cleavage procedure from the novel functionalised resin showed that only the peptides containing deoxyfructosyl-lysine moieties can be efficiently and specifically detected by HR-MS and MS/MS experiments. We also investigated the high-selective affinity to deoxyfructosylated peptides in an ad hoc mixture containing unique synthetic non-modified peptides and in the hydrolysates of human and bovine serum albumin as complex peptide mixtures. We demonstrated that the deoxyfructopyranosyl moiety on lysine residues is crucial in the capturing reaction. Therefore, the novel specifically-designed PhB-Lys(PhB)-ChemMatrix® Rink resin, which has the highest affinity to deoxyfructosylated peptides, is a candidate to quantitatively separate early glycation peptides from complex mixtures to investigate their role in diabetes complications in the clinics.
