Abstract
The development of bifunctional platinum complexes with the ability to interact with DNA via different binding modes is of interest in anticancer metallodrug research. Therefore, we report platinum(II) terpyridine complexes to target DNA by coordination and/or through a tethered alkylating moiety. The platinum complexes were evaluated for their in vitro antiproliferative properties against the human cancer cell lines HCT116 (colorectal), SW480 (colon), NCI-H460 (non-small cell lung), and SiHa (cervix) and generally exhibited potent antiproliferative activity although lower than their respective terpyridine ligands. 1H NMR spectroscopy and/or ESI-MS studies on the aqueous stability and reactivity with various small biomolecules, acting as protein and DNA model compounds, were used to establish potential modes of action for these complexes. These investigations indicated rapid binding of complex PtL3 to the biomolecules through coordination to the Pt center, while PtL4 in addition alkylated 9-ethylguanine. PtL3 was investigated for its reactivity to the model protein hen egg white lysozyme (HEWL) by protein crystallography which allowed identification of the Nδ1 atom of His15 as the binding site.

Abstract
The function of RNA depends on its ability to adopt complex and dynamic structures, and the incorporation of site-specific cross-linking probes is a powerful method for providing distance constraints that are valuable in RNA structural biology. Here we describe a new RNA-RNA cross-linking strategy based on Pt(II) targeting of specific phosphorothioate substitutions. In this strategy cis-diammine Pt(II) complexes are kinetically recruited and anchored to a phosphorothioate substitution embedded within a structured RNA. Substitution of the remaining exchangeable Pt(II) ligand with a nucleophile supplied by a nearby RNA nucleobase results in metal-mediated cross-links that are stable during isolation. This type of cross-linking strategy was explored within the catalytic core of the Hammerhead ribozyme (HHRz). When a phosphorothioate substitution is installed at the scissile bond normally cleaved by the HHRz, Pt(II) cross-linking takes place to nucleotides G8 and G10 in the ribozyme active site. Both of these positions are predicted to be within ~8 Å of a phosphorothioate-bound Pt(II) metal center. Cross-linking depends on Mg(2+) ion concentration, reaching yields as high as 30%, with rates that indicate cation competition within the RNA three-helix junction. Cross-linking efficiency depends on accurate formation of the HHRz tertiary structure, and cross-links are not observed for RNA helices. Combined, these results show promise for using kinetically inert Pt(II) complexes as new site-specific cross-linking tools for exploring RNA structure and dynamics.

Abstract
The response to pathogens and damage in plants and animals involves a series of carefully orchestrated, highly evolved, molecular mechanisms resulting in pathogen resistance and wound healing. In metazoans, damage- or pathogen-associated molecular pattern molecules (DAMPs, PAMPs) execute precise intracellular tasks and are also able to exert disparate functions when released into the extracellular space. The emergent consequence for both inflammation and wound healing of the abnormal extracellular persistence of these factors may underlie many clinical disorders. DAMPs/PAMPs are recognized by hereditable receptors including the Toll-like receptors, the NOD1-like receptors and retinoic-acid-inducible gene I-like receptors, as well as the receptor for advanced glycation end products. These host molecules 'sense' not only pathogens but also misfolded/glycated proteins or exposed hydrophobic portions of molecules, activating intracellular cascades that lead to an inflammatory response. Equally important are means to not only respond to these molecules but also to eradicate them. We have speculated that their destruction through oxidative mechanisms normally exerted by myeloid cells, such as neutrophils and eosinophils, or their persistence in the setting of pathologic extracellular reducing environments, maintained by exuberant necrotic cell death and/or oxidoreductases, represent important molecular means enabling chronic inflammatory states.

Abstract
(2,2':6',2"-terpyridine)platinum(II) complexes possess pronounced cytostatic activities against trypanosomes and leishmania. As shown here, the complexes are irreversible inhibitors of trypanothione reductase (TR) from Trypanosoma cruzi, the causative agent of Chagas' disease. The most effective derivatives are the (4'-chloro-2, 2':6',2"-terpyridine)platinum(II) ammine and the (4-picoline)(4'-p-bromophenyl-2,2':6',2" -terpyridine)platinum(II) complexes which in the presence of NADPH inhibit TR with second-order rate constants of about 1.3 x 10(4) M(-1) s(-1). The modified enzyme species possess increased oxidase activities. The inhibition is not reversed upon dialysis or treatment with low-molecular-mass thiols. Kinetic and spectroscopic data suggest that Cys52 in the active site has been specifically altered. Inhibition of this key enzyme of parasite thiol metabolism probably contributes to the antitrypanosomal activity of the compounds. In contrast to the parasite enzyme, most (terpyridine)platinum complexes interact only reversibly with human glutathione reductase and an initial inhibition is completely abolished during the course of the assay.

Abstract
Reactions of cis-[Pt(NH(3))(NH(2)C(6)H(11))Cl(OH(2))](+) with d(Tp(S)T) and d(T(n)()p(S)T(16)(-)(n)()), n = 1, 4, 8, 12, and 15, were investigated by use of HPLC in an aqueous medium with pH 4.1 +/- 0.1 and sodium and magnesium ion concentrations varying between 1.5 mM and 0.50 M. Platination of the oligonucleotide fragments is favored over platination of d(Tp(S)T) in the whole salt concentration interval studied. The maximum rate enhancement after incorporation of the p(S)-site into the polymeric DNA environment is observed for d(T(8)p(S)T(8)), which reacts up to ca. 500 times faster than d(Tp(S)T), after suitable changes of the cation concentrations in the reaction medium. The platination rates of the oligonucleotide fragments d(T(n)()p(S)T(16)(-)(n)()) decrease with increasing salt concentration. For a given phosphorothioate position, the rate also decreases when the cations in the medium are changed from Na(+) or K(+) to Mg(2+), even at constant ionic strength. The reactions with embedded p(S)-sites in d(T(n)()p(S)T(16)(-)(n)()), n = 4, 8, and 12, were found to be kinetically favored over reactions with the 5'- and 3'-end positions. In a reaction medium containing monovalent cations there is a strong preference for platination of d(T(8)p(S)T(8)), whereas d(T(4)p(S)T(12)) and d(T(12)p(S)T(4)) show intermediate reactivity compared with fragments with n = 1 and 15. In contrast, no kinetic discrimination is found between the p(S)-sites in d(T(n)()p(S)T(16)(-)(n)()), n = 4, 8, and 12, in the presence of Mg(2+). The results are interpreted in terms of a general mechanism where preaccumulation of the cationic Pt(II) complex on the oligomers is required for product formation. The kinetics are consistent with a reaction model that includes release of cations from the DNA surface during the adduct formation process.

Abstract
We have investigated the efficiency with which PtII complexes cross-link phosphorothioates of oligonucleotides to complementary DNA targets. The A and G residues 2-5 bases downstream from the 5'-phosphorothioate group are preferred sites for cross-linking. Replacement of residues in this part of the target by T residues results in greatly decreased cross-linking when cis platinum diammine dichloride (cisPtII) or potassium platinous chloride (K2PtCl4) are used. Trans platinum diammine dichloride (transPtII) forms cross-links with T residues if A and G residues are absent from the susceptible region of the target. Oligomers containing an internal phosphorothioate group can also be linked to their templates with transPtII, but not with cisPtII or K2PtCl4. Cross-linking via an internal phosphorothioate group tends to be less efficient than cross-linking via a 5'-terminal phosphorothioate. The Sp isomers of internal phosphorothioates are cross-linked more efficiently than the Rp isomers. Preliminary experiments suggest that the efficiency of cross-linking to RNA targets will prove similar to that found for DNA targets.

Abstract
Two novel complexes of Pd(II) involving vitamin B6 compounds have been synthesized. They are compatible with the compositions Pd(P.H.)2 C2(P = pyridoxol) and Pd(PL.H)2 C2(PL = pyridoxal). The complexes inhibited the growth as well as the biosynthesis of RNA, DNA, and protein of E. coli B-766. Photoacoustic spectral (PAS) measurements showed that the complexes bound to DNA of the bacteria and were present only in the kidney of treated mice. The complexes inhibited the incorporation of 3H-thymidine as well as 14C-leucine in the DNA and protein, respectively, of liver cell cultures (BL8L). The inhibition of cell division of Walker-S-cells and human lymphocytes by the complexes was highly significant.

Abstract
Adult female rats were treated intraperitoneally with 8 mg/kg of cis-dichlorodiammineplatinum(II). At various times after treatment 1, 3, 5, 8, 12 days replicate animals were killed and liver and kidney cytosols examined for activity of glutathione-dependent transferase activities and levels of glutathione. Hepatic levels of glutathione were depressed by 13-28% at 1, 3, 5 days after dosing. Renal levels of glutathione were increased by 3-5 fold at 8 and 12 days after drug administration. Renal levels of glutathione were decreased at nearly all times studied with a nadir at 5 days. Activity of glutathione s-acryl transferase was increased and S-epoxidetransferase was decreased at 5, 8, 12 days after dosing. When cisplatinum was added to incubation mixtures in vitro, no changes in enzyme activities were observed. When cisplatin and reduced glutathione were determined chromatographically in tissue cytosols from treated rats, 30% of the recovered platinum was associated with glutathione. In tissue cytosols, greater than 95% of the total platinum content was retained in the supernatant when protein was precipitated with trichloroacetic acid, while only 3-5% of the protein was retained.

Abstract
Yeast tRNAPhe containing a phosphorothioate modified -CS-CS-A terminus binds two moles of chloroterpyridineplatinum(II). This result was determined by titrating the tRNA with [3H](terpy)PtCl] Cl, removing excess platinum by cation exchange chromatography, and determining the amount of bound platinum by radiocounting techniques. It has thus been established that adjacent phosphorothioate modified nucleotides can be labeled with an electron dense stain, a necessary requirement for electronmicroscopic sequencing of polynucleotides to become practical.

Abstract
Tetrakis(acetoxymercuri)methane binds to the sulfur atom of 6-thioguanosine and also to the 4-thiouridine residue of Escherichia coli tRNAVal. A 4:1 complex is formed between 6-thioguanosine and tetrakis(acetyoxymercuri)methane. Addition of 3 equivalents of N,N-dimethyl-2-amino-ethanethiol hydrochloride to tetrakis(acetoxymercuri)methane effectively blocks three of the four mercury atoms, rendering the compound monofunctional toward 6-thioguanosine. Under appropriate conditions, tetrakis(acetyoxymercuri)methane, in the presence or absence of N,N-dimethyl-2-amino-ethanethiol hydrochloride, binds to the 4-thiouridine residue in E. coli tRNAVal without forming intermolecular crosslinks. These results suggest that tetrakis(acetoxymercuri)methane will be a useful polymetallic reagent for labeling sulfur sites in polynucleotides. It may also prove to be a valuable reagent for preparing heavy metal derivatives of proteins for x-ray crystallographic study.
