Binding metal ions

Macroheterocycles as components of molecular ensembles for metal ion binding 98PAC2345. [Pg.220]

The importance of one other type of reaction that metal ions undergo has been recognized and studied extensively in the past 40 years. This reaction is adsorption, in which metal ions bind to the surface of particulate matter and are thereby transported as part of a solid phase even though they do not form an identifiable precipitate. Conceptually, these reactions can be thought of as hybrids between complexation and precipitation reactions. Most studies of these reactions have used metal oxides or hydroxides as the solid (adsorbent) phase, and the... [Pg.391]

To determine the selectivity scale of metal ions binding by pectins by means of pH measurements, we assumed that the exchange of the protons carried by carboxyl functions by metal ions involved a pH-decreasing which is more pronounced when the affinity of pectins for a given metal ion is higher. [Pg.536]

Certain kinds of metal ions bind to the DNA double strands by an electrostatic interaction with the phosphate group(s) or by complex formation with the sugar moiety or the nucleic... [Pg.527]

One approach, pursued by two groups in particular, is to use model nucleobases that feature an additional metal-ion binding group. Gokel and co-workers have used this strategy with aza-crown derivatives (50,51). X-ray crystallography of 6is-(3-(l-thyminyl)propyl)-4,13-diaza-18-crown-6, 4, reveals the Na+ is coordinated by T-02 [Na-0 distances 2.488 and 2.468 Al (51). Aza-crown derivatives with multiple base substi-... [Pg.99]

A series of amine-tethered nucleobases such as 8 has also been developed. These ligand systems have allowed the interaction of d-block metal ions with the N3pUrine site to be probed and an indication of base-specific metal-ion binding has begun to emerge (55-58). [Pg.102]

Of all the known sites for metal-ion binding to the heteroatoms of DNA bases, G-N3 is the most elusive. The adjacent 2-amino group is often considered to offer steric hindrance to binding at this site. However, while this undoubtedly influences the chemistry it does not preclude binding. The tri-metalated [ [Pt(N]3(9-Et G N1,N3,N7)]5 compound has for many years been the only structurally characterized example of an N3-coordinated guanine (66). A second example has now been reported, the tetranuclear octacation 16 (56). In this complex both the N7 and N3 atoms are bound to Pd2+ (Fig. 22). The molecule presents an interesting new architecture for a guanine-tetramer. Such structures are well known in DNA chemistry and are almost inevitably metal-ion stabilized (67,68). [Pg.109]
