Abstract
PT-ACRAMTU ([PtCl(en)(ACRAMTU-S)](NO(3))(2), en = ethane-1,2-diamine, ACRAMTU = 1-[2-(acridin-9-ylamino)ethyl]-1,3-dimethylthiourea) is a cytotoxic platinum-acridine conjugate previously shown to form adducts with the N3 endocyclic nitrogen of adenine in the DNA minor groove. This unusual observation and our prior determination of the pronounced 5'-TA/TA base-step affinity of the drug have prompted us to investigate effects of these adducts on DNA minor groove binding proteins. Here, we used electrophoretic mobility shift assays to study the recognition of a PT-ACRAMTU-modified TATA box sequence by TATA-binding protein (TBP). The frequency of PT-ACRAMTU adducts in the minor groove of the TATA box was varied by selective elimination of potential major groove and minor groove binding sites in a 24-bp probe sequence through incorporation of deaza nucleobases. The most dramatic effect on TBP binding was observed in a duplex substituted with 7-deaza-G and 7-deaza-A, which reduced binding by as much as 73% compared to an unplatinated duplex. In contrast, elimination of A-N3 binding sites had no significant effect on TBP binding, suggesting that minor groove adducts of PT-ACRAMTU are the cause of inhibition. This notion was further corroborated by efficient platinum-mediated photo-cross-linking of the drug-modified DNA to TBP. PT-ACRAMTU appears to be the first platinum-based drug capable of targeting DNA sequences critical for transcription initiation. The biological consequences of PT-ACRAMTU's minor groove adducts are discussed.

Abstract
Two square planar derivatives of Pt(en)Cl(2) with intrinsic fluorescence in aqueous solution at room temperature, with quantum yields (Phi) 0.11 and 0.10, respectively, have been synthesized and characterized as [Pt(en)(CG)Cl] (Complex 1) and [Pt(en)(CG)(2)] (Complex 2) (en = ethylenediamine, CG = cholylglycinate). Complexes 1 and 2 exchange just one ligand (chloride or cholylglycinate, respectively) when reacted with water or 5'-GMP to give the same chemical species. After reaction with DNA oligonucleotides or DNA plasmids, they show enhanced emission in the visible region, which lasts for long periods of time and makes them potentially useful DNA marker molecules. Incubation with nucleated blood cells followed by microscopic analyses revealed that they enter the cells within minutes of exposure, selectively stain the DNA, and persist after more than 48 h of exposure. Complexes 1 and 2 display cell cycle phase-independent cytotoxic activity against cisplatin-resistant CHO (Chinese hamster ovarian) tumor cells, with an early onset of their effects. Their slightly different biological effects, as compared to cisplatin, are considered to be linked to the bile acids and their vector properties and to the preferential formation of monoadducts.

Abstract
The guanine- N7 monoadduct of [Pt(en)Cl(ACRAMTU)](NO(3))(2) (PT-ACRAMTU; en=ethane-1,2-diamine, ACRAMTU=1-[2-(acridin-9-ylamino)ethyl]-1,3-dimethylthiourea), a dual metalating/intercalating cytotoxic agent, was generated in a double-stranded dodecamer, d(CCTCTCG*TCTCC/GGAGACGAGAGG) (III*), and isolated by preparative reverse-phase high-performance liquid chromatography (HPLC). The adduct was characterized using matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS), circular-dichroism spectropolarimetry (CD), UV-melting curves, and NMR spectroscopy. In addition, a molecular mechanics/restrained molecular dynamics (MM/rMD) study was performed for this adduct using the AMBER force field. Monoadduction of the sequence leads to a pronounced increase in melting temperature, Delta T(m)= T(m)(III*)- T(m)(III)=9.7 degrees C. Because there is complete enthalpy-entropy compensation, binding occurs without noticeable thermodynamic destabilization. This feature and the CD (induced-ligand circular dichroism) and NMR (upfield shifts of aromatic acridine proton signals) data are indicative of a unique, nondenaturing dual-binding mode that involves partial intercalation of the acridine chromophore. An energy-minimized AMBER model ofIII* demonstrates that platination of G7- N7 of guanine in the major groove and partial insertion of the acridine moiety into the C6G19/G7C18 base step on the 5' face of the modified purine base is feasible and supportive of the experimental results. Differences in the biophysical properties betweenIII* and duplexes containing adducts of the clinical-drug cisplatin are outlined, and possible biological consequences are discussed.

Abstract
The synthesis, characterization, and molecular interactions of platinum(II) coordination compounds, which contain a distal nonradioactive reporter molecule, with mono- and polynucleotides are described. A [Pt(II)(en)(NH(2)(CH(2))(6)NH-tBoc)Cl](NO(3)) (en=ethylenediamine) entity has been coupled, after removal of the tBoc group, to a number of hapten and fluorophore molecules through succinimide derivatives. The influence of the various tethered reporter groups within these complexes on the reactivity towards guanosine 5'-monophosphate (5'-GMP), as a model for polynucleotide sequences, was investigated to shed light on the use of these reagents in hybridization assays. Reactivity turned out to be strongly dictated by the chemical nature of the distal reporter molecule present. At pH 7.0 the sequence of reactivity is cationic approximately aromatic (stacking) > neutral > anionic; there is approximately an order of magnitude difference between the fastest reacting complex (k=10.2 x 10(-2) M(-1) s(-1)) and the slowest reacting complex (k=0.93 x 10(-2) M(-1) s(-1)) under these conditions. Platination of an oligodeoxynucleotide (30-mer), dsDNA, or an RNA transcript, shows that a Pt/nucleotide ratio between 1:10 and 1:20 (established by using flameless atomic absorption spectroscopy) results in probes with excellent hybridization characteristics. In terms of applicability and detection limits these platinated nucleic acid probes perform equally well compared to conventionally generated nucleic acid probes, that is, through enzymatic incorporation of covalently labeled nucleotide triphosphates. Applications of these reagents to in situ hybridization assays and gene expression profiling on microarrays illustrate the potential of these monofunctional binding platinum triamine compounds.

Abstract
The interaction of the anticancer antibiotic altromycin B and its isostructrural Pt(II) and Pd(II) metal complexes with native calf thymus (CT) DNA was studied using UV-thermal denaturation experiments, circular dichroism spectroscopy and temperature controlled spectrophotometric titrations. Altromycin B stabilizes the double helix by raising the T(m), mainly by intercalation of its chromophore between the base pairs and interacting electrostatically via its sugar moieties with the edges of the DNA helix. Moreover, altromycin B induces a B-->A structural transition of CT DNA. The effect on DNA stability and conformation depends on the metal ion. Pt(II) and Pd(II) complexes induce the B-->A structural transition and stabilize the double helix similarly but they present lower final hyperchromicity due to premelting effects which were caused by intra- and interstrand crosslinking. Thus, a synergic effect of the metal ions to altromycin B-CT DNA interaction is observed in both cases. Altromycin B interacts with 5'-GMP, 5'-AMP and 5'-CMP by electrophilic attack of the opened epoxide ring to the N(7)G, N(1)/N(7)A and N(3)C. Thus, covalent binding between these nucleotides and altromycin B takes place and explain the multiple binding mode suggested by the studies of the interaction of altromycin B and its complexes with DNA. The [Pd(II)-altroB] complex dissociates in the presence of the nucleotides, and various species of Pd(II)-nucleotide complexes, especially with 5'-GMP, are formed. The [Pt(II)-altroB] complex dissociates too, but only one or two species of Pt(II)-nucleotide complexes are formed, and in the case of 5'-AMP interaction the formation of a tertiary altroB-Pt(II)-5'AMP complex is proposed. 5'-TMP reacts very weakly in comparison with the other three nucleotides. These interactions were followed by 1H-NMR.

Abstract
The development of metal-based antitumor drugs has been stimulated by the clinical success of cis-diamminedichloroplatinum(II) (cisplatin) and its analogs and by the clinical trials of other platinum and ruthenium complexes with activity against resistant tumors and reduced toxicity including orally available platinum drugs. Broadening the spectrum of antitumor drugs depends on understanding existing agents with a view toward developing new modes of attack. It is therefore of great interest to understand the details of molecular and biochemical mechanisms underlying the biological efficacy of platinum and other transition-metal compounds. There is a large body of experimental evidence that the success of platinum complexes in killing tumor cells results from their ability to form various types of covalent adducts on DNA; thus, the research of DNA interactions of metal-based antitumor drugs has predominated. The present review summarizes current knowledge on DNA modifications by platinum and ruthenium complexes, their recognition by specific proteins, and repair. It also provides strong support for the view that either platinum or ruthenium drugs, which bind to DNA in a fundamentally different manner from that of 'classical' cisplatin, have altered pharmacological properties. The present article also demonstrates that this concept has already led to the synthesis of several new unconventional platinum or ruthenium antitumor compounds that violate the original structure-activity relationships.
