  Synthesis and Characterization of Fluorescent Displacers for Online Monitoring of Displacement Chromatography

  摘要：

  One of the major impediments to the implementation of displacement chromatography for the purification of biomolecules is the need to collect fractions from the column effluent for time-consuming off line analysis. The ability to employ direct online monitoring of displacement chromatography would have significant implications for applications ranging from analytical to preparative bioseparations. To this end, a set of novel fluorescent displacers were rationally designed using known chemically selective displacers as a template. Fluorescent cores were functionalized with different charge moieties, creating a homologous library of displacers. These compounds were then tested on two protein pairs, alpha-chymotrypsinogen A/ribonuclease A and cytochrome c/lysozyme, using batch and column displacement experiments. Of the synthesized displacers, two were found to be highly selective while one was determined to be a high-affinity displacer. Column displacements using one of the selective displacers yielded complete separation of both protein pairs while facilitating direct online detection using UV and fluorescence detection. Saturation transfer difference NMR was also carried out to investigate the binding of the fluorescent displacers to proteins. The results indicated a selective binding between the selective displacers and (x-chymotrypsinogen A, while no binding was observed for ribonuclease A, confirming that protein-displacer binding is responsible for the selectivity in these systems. This work demonstrates the utility of fluorescent displacers to enable online monitoring of displacer breakthroughs while also acting as efficient displacers for protein purification.

  data establish that Pt(DNS-dien) has a Pt-C8 bond and a Pt-N(sulfonamido) bond. Pt(DNSH-dien)Cl and [Pt(DNSH-tren)Cl]Cl bind to N7 of 6-oxopurines (e.g., 5'-GMP, 3'-IMP, and 9-ethylguanine) and sulfur of methionine (met). Competition and challenge reactions for Pt(II) with met and 5'-GMP typically reveal that met binding is favored kinetically but that 5'-GMP binding is favored thermodynamically. This

  A modified cyclodextrin containing a dansyldiethylenetriamine metal-binding group (6-deoxy-6-N(N''-dansyldiethylenetriamino)-beta-cyclodextrin, CD-dien-DNS) was synthesized. The conformation of CD-dien-DNS was studied by 2D NMR (ROESY spectral in D2O, by circular dichroism, and by fluorescence. The results were compared with those previously obtained with the analogous 6-deoxy-6-N-(N'-dansylethylenediamino)-beta-cyclodextrin (CD-en-DNS) and were consistent with the self-inclusion of the dansyl group within the macrocycle cavity. However, the orientation of the dansyl group for CD-dien-DNS was found to be equatorial, whereas for CD-en-DNS it was axial, suggesting a dependence of the orientation of the dansyl group upon the length of the linker. In the presence of lipophilic organic molecules, CD-dien-DNS showed sensing properties similar to those observed for CD-en-DNS, suggesting a similar ''in-out'' movement of the dansyl group, due to competitive inclusion of the guest. Unlike CD-en-DNS, CD-dien-DNS was found to be a fluorescent chemosensor for copper(II) ion, with a linear response up to a 1:1 molar ratio, suggesting that a more flexible conformation of the linker and the presence of additional binding sites allow binding of the metal ion by the amino and sulfonamidate groups. Good selectivity for Cu(II), when compared with Fe(II), Co(II), Ni(II), and Zn(II), was observed. The CD-dien-DNS copper(II) complex was shown to behave as a chemosensor for bifunctional molecules, such as amino acids. In fact, upon addition of alanine, tryptophan, and thyroxine, the negligible fluorescence intensity of Cu(CD-dien-DNS) complex was ''switched on'', with a response dependent on the amino acid side chain.
