Abstract

Interaction of a predesigned molecular "clip" (4) with rigid dipyridyl bridging ligands, in acetone/water mixtures, leads to the formation of molecular rectangles (5-8) in 92-97% isolated yields via spontaneous self-assembly. Characterization was accomplished with multinuclear NMR and UV-vis spectroscopy, FAB mass spectrometry, and X-ray crystallography. The length of these metallamacrocycles ranges from 2 to 3 nm. Postmodification via non-nucleophilic counterion exchange results in enhanced structural integrity for the assemblies.

Luminescence quenching of tris(2,2'-bipyridine)ruthenium(II) by 2,6-dimethylphenol and 4-bromo-2,6-dimethylphenol in sol-gel-processed silicate thin films.

The luminescence properties of tris(1,2-bipyridine)ruthenium(II) (Ru(bpy)(3)(2+)), included in different organically modified silicate gel matrixes were investigated. Spin and dip-coated thin films were prepared from methyltrimethoxysilane (MTMOS) and methyltriethoxysilane (MTEOS). A blue shift in the emission spectrum of the MLCT excited state of Ru(bpy)(3)(2+) with respect to the aqueous solution was observed in all the films, practically independent of the reaction pH used to prepare the "sol," silane-derived precursor, and procedure used (dip-coating or spin-coating) to obtain the film. A bimodal distribution of probe sites in the films was obtained from modeling of the emission decays by a double exponential and from application of the exponential series method. The parameters of the decay components depended principally on the thermal treatment used in the processing of the films. The lifetimes decreased with the increase in the drying temperature of the films; at the same time, the emission spectra showed a red shift and the luminescence efficiency decreased. A luminescence quenching of the ruthenium complex in the films by 4-bromo-2,6-dimethylphenol and 2,6-dimethylphenol in aerated aqueous solution at pH 12 in contact with the film was also observed. The quenching plots obtained from luminescence intensities or luminescence intensity decay measurements showed a downward curvature. These plots could be fitted satisfactorily by a sum of two Stern-Volmer terms with quenching constants K(SV1) and K(SV2) associated with two different binding sites of the ruthenium complex. This result is indicative of the matrix microheterogeneity in the films and is fully consistent with the biexponential nature of the luminescence intensity decay profiles. The Stern-Volmer parameter values for both sites in the films suggest that only a low percentage of the probe is accessible to the quencher and its respective constant K(SV1) is lower than in water.

Effect of iron limitation on the growth and cytotoxin production of Salmonella choleraesuis SC-5.

This study investigated the effect of iron limitation on the growth and cytotoxin production of Salmonella choleraesuis and examined the iron-accruing capability of various Salmonella strains. It was found that the growth of S. choleraesuis SC-5 was retarded by the presence of iron-chelating agents, 2,2'-dipyridyl or ethylenediamine di-o-hydroxyphenylactic acid (EDDA). Addition of 2,2'-dipyridyl to Trypticase soy broth (TSB) resulted in a smaller maximum population of S. choleraesuis noted at the stationary phase, while addition of EDDA in TSB only caused an extended period of lag phase. A significant increase in cytotoxin production was found when S. choleraesuis SC-5 was cultured in iron-limited TSB containing 2,2'-dipyridyl. On the other hand, pre-culture in an iron-limited medium increased the growth of S. choleraesuis SC-5 in mouse serum with or without complement inactivated. Testing with a plate assay method revealed that the ability and efficiency of Salmonella to acquire iron under iron-limited condition varied with strains, and the kinds and dosages of iron-containing compounds present.

Probing the solvent accessibility and electron density of adenine: oxidation of 7-deazaadenine in bent DNA and purine doublets.

The effect of DNA bending on nucleobase electron transfer was investigated by studying the oxidation of double-stranded sequences containing seven repeats of the known bent sequence d(GGCA(1)A(2)A(3)A(4)A(5)A(6)C) where 7-deazaadenine (zA) was substituted at the A(3) position. Native gel electrophoresis was used to show that the sequence remained bent upon substitution of zA, which provides for oxidation of the sequence by Ru(bpy)(3)(3+) (bpy = 2,2'-bipyridine). The Ru(III) oxidant was generated by photolysis of Ru(bpy)(3)(2+) in the presence of ferricyanide, and the oxidation was visualized by high-resolution gel electrophoresis of the radiolabeled DNA sequence following base treatment. Cleavage of the DNA strand at the guanine residues and at the zA residues was observed. Comparison of the oxidation of zA in bent DNA versus the normal B form showed that hybridization of the B form sequence to its Watson-Crick complement produced a reduction in cleavage by a factor of 5.19 +/- 0.46 while hybridization of the bent sequence only reduced cleavage by a factor of 1.58 +/- 0.23. This result implies that the zA in the double-stranded, bent sequence is much more solvent-exposed than in normal B-form DNA. When the zA occurred in a B-form 5'-zA-G doublet, the reactivity was 6.63 +/- 0.10 times higher for the zA compared to the G. This implies an even greater effect of a 3'-guanine on the oxidation potential of zA than in the well-known 5'-GG doublet.
