Synthesis of hydroxycinnamic acid glucuronides and investigation of their affinity for human serum albumin

Hydroxycinnamic acids (HCAs) are among the most abundant dietary polyphenols. Recent bioavailability studies have shown that HCAs enter the blood circulation mainly as glucuronides, which are thus most likely to express their potential health effects. In this work, an efficient synthesis of HCA O-arylglucuronides is developed. As for many xenobiotics, the resilience of HCA O-arylglucuronides in plasma and subsequent delivery to tissues could be governed by their binding to human serum albumin (HSA). Hence, the affinity of HCA O-arylglucuronides for HSA and its possible binding site were investigated by fluorescence spectroscopy. HCA O-arylglucuronides turn out to be moderate HSA ligands (K in the range 1-4 ¡Á 104 M-1) that bind HSA in sub-domain IIA, competitively or noncompetitively with other sub-domain IIA ligands such as dansylamide and the flavonol quercetin.

Adaptation of a thermospray liquid chromatography/mass spectrometry interface for use with alkaline anion exchange liquid chromatography of carbohydrates

An interface is described that allows the direct coupling of high-performance alkaline anion exchange liquid chromatography with thermospray mass spectrometry. A membrane suppressor is used to remove nonvolatile alkaline salts from the mobile phase after the chromatographic process is completed and prior to introduction into the mass spectrometer. Examples are given of both isocratic and gradient separations of a three-component test mixture of N-acetyiated mono- and disaccharides, followed by on-line mass spectral data acquisition. Sensitivity studies show minimum detection limits for the test compounds to be in the microgram range.

Blue luminescent zinc(II) complexes with polypyridylamine ligands: Crystal structures and luminescence properties

A series of blue luminescent zinc(II) complexes, [Zn(dpa)X2] [dpa = di-2-pyridylamine, X = OAc 1a, Cl 1b, CN 1c or 4-MeC6H4S 1d], [Zn(dpa)2][CF3SO3]2 2, [Zn(tpda)X2] [tpda = 2,6-bis(2-pyridylamino)pyridine, X = OAc 3a or Cl 3b] and [Zn(tpda)(CF3SO3)2] 4 has been prepared. Their molecular structures, except complex 4, have been established by X-ray crystallography. In the crystal lattice of 2 the [Zn(dpa)2]2+ cations and CF3SO3- anions are disposed in pairs via intermolecular hydrogen bonds [N(2)…O(2) 2.865(4) A]. The crystal packing of [Zn(dpa)(OAc)2] 1a revealed that two adjacent molecules associate in pairs through intermolecular hydrogen bonding [N(2) …O(4?) 2.816(3) A]. However, the crystal lattice of its tpda derivative 3a shows that the molecules are linked by extensive intermolecular hydrogen bonding between the amino groups and the acetate ligands [N(2)…O(2?) 2.805(3) and N(4)…O(4?) 2.860(3) A] resulting in an interlocking hydrogen bond network. Polymeric one-dimensional tapes are generated through extended pi-pi stacking interactions between the molecules of [Zn(dpa)(4-MeC6H4S)2] 1d, and the thiolate groups are aligned in an all-anti conformation along the metal chain. In the case of [Zn(dpa)(CN)2] 1c, co-operative intermolecular hydrogen bonds and aromatic pi-pi interactions in its solid state lead to a supramolecular two-dimensional sheet. All the zinc(II) complexes display high energy intraligand 1(pi-pi*) fluorescence in degassed MeOH at 298 K, and intraligand 3(pi-pi*) phosphorescence in a glassy solution (MeOH-EtOH 1:2 at 77 K). An emission band observed for 1c (418 nm) and 1d (481 nm) in their solid state emission spectra is ascribed to excimeric emission due to aromatic pi-pi interactions.
