Abstract
Recent emergence of FTIR spectromicroscopy (micro-FTIR) as a dynamic spectroscopy for imaging to study biological chemistry has opened new possibilities for investigating in situ drug release, redox chemistry effects on biological molecules, DNA and drug interactions, membrane dynamics, and redox reactions with proteins at the single cell level. Micro-FTIR applied to metallodrugs has been playing an important role since the last decade because of its great potential to achieve more robust and controlled pharmacological effects against several diseases, including cancer. An important aspect in the development of these drugs is to understand their cellular properties, such as uptake, accumulation, activity, and toxicity. In this review, we present the potential application of micro-FTIR and its importance for studying metal-based drugs, highlighting the perspectives of chemistry of living cells. We also emphasise bioimaging, which is of high importance to localize the cellular processes, for a proper understanding of the mechanism of action.

Application of capillary electrophoresis technique for the enantioseparation of bioactive ferrocene-based compounds versus DFT calculated data. Electrophoresis 2020; 41:1969-1979.

Abstract
Herein, a series of bioactive ferrocene-modified N-heterocycles with alkyl linkers was prepared in good to quantitative yields starting from easy accessible ferrocene alcohols and heterocycles under acidic or neutral (for imidazole) conditions in racemic forms. The analytical resolution of a number of bioactive racemic ferrocene azoles 1-6 (where azole = imidazole, pyrazole, and benzotriazole derivatives) into enantiomers was first carried out by CE using sulfobuthylether-β-CD (captisol) as a chiral selector. The analytical approaches to highly enantiomeric-enriched ferrocene derivatives are based on the formation of their inclusion complexes. The best chiral separation was achieved using zone CE in a quartz capillary. The ACE was used to evaluate the stability constants of captisol complexes with enantiomeric forms of two ferrocene derivatives 1, FcCHMe-imidazole, and 6, FcCHMe-benzotriazole. The optimal conditions for the resolution of the studied (R, S)-ferrocene compounds 1, 2, and 6 were predicted on the basis of the performed quantum chemical calculations and then implemented by the electrophoretic method. A high correlation between density functional theory calculation results and experimental electrophoresis data were obtained. Successful enantioseparation of racemic mixtures is of great importance for the characterization and further applications of drug candidates in enantiopure forms and in the development of clinical treatment. The advantages of the CE procedure make it possible to have important practical value and significance for determining the purity and enantiomeric excess of other ferrocene-containing compounds.

Abstract
Cisplatin and its second and third generation analogues are widely used in the treatment of cancer. To study their reactions with proteins, we present a method based on SDS-PAGE separation and laser ablation-inductively coupled plasma-mass spectrometry (LA-ICP-MS) for platinum detection in the reaction between human serum albumin (HSA) and cisplatin. We developed matrix-matched standards of HSA/cisplatin mixtures and used them to quantify the amount of adducts formed at different HSA:cisplatin ratios. We noted that cisplatin incubation with HSA resulted in the formation of higher order HSA n-mers, depending on the amount of cisplatin added. This caused a depletion of the HSA dimer bands, while the majority of HSA was present as the monomer. Inducing the formation of such higher molecular weight species may have an impact on the mode of action of metallodrugs.

Abstract
Mass spectrometry (MS) has emerged as an important tool for studying anticancer metallodrugs in complex biological samples and for characterising their interactions with biomolecules and potential targets on a molecular level. The exact modes-of-action of these coordination compounds and especially of next generation drug candidates have not been fully elucidated. Due to the fact that DNA is considered a crucial target for platinum chemotherapeutics, metallodrug-DNA binding studies dominated the field for a long time. However, more recently, alternative targets were considered, including enzymes and proteins that may play a role in the overall pharmacological and toxicological profile of metallodrugs. This review focuses on MS-based techniques for studying anticancer metallodrugs in vivo, in vitro and in situ to delineate their modes-of-action.

Abstract
The development of DNA-targeted next-generation platinum-based anticancer chemotherapeutics is often accompanied by studies on the reactivity to DNA models. However, the incubation conditions used in literature vary widely, and some of the buffer/salts used are known to form complexes with Pt. Such coordination can influence the binding process and also the adducts formed. In a systematic approach, studies on the binding of cisplatin (1 mM) to dGMP (2 mM) in a series of different incubation solutions of relevance to biological systems are reported, employing capillary zone electrophoresis (CZE) with UV/vis and electrospray ionization-mass spectrometric (ESI-MS) detectors. Kinetic experiments performed with CZE-UV showed a high reactivity of dGMP to cisplatin in pure water (τ(1/2) = 4.1 ± 0.7 h) but a significantly slowed down in a solution containing a carbonate/phosphate buffer supplemented with NaCl, resulting in a half-life of dGMP of 25 ± 3 h. Especially carbonate had a major impact on the binding, though no coordination to the metal center was detectable with the methods used. The only adducts containing buffer components were (phosphate)Pt and tris(ammine)Pt species, as identified by means of CZE-ESI-MS, in addition to the main adduct [Pt(NH3)2(dGMP)2 - 4H(+)](2-) and other less abundant Pt-containing species.

Abstract
Anticancer chemotherapeutics with new modes of action are in great demand to overcome adverse effects, resistance problems and a limited application range. Among other approaches, trans-configured analogs of the established chemotherapy drug cisplatin show promising results in biological model systems. Herein we report on comparative studies on the stability of cis- and trans-[dihalidobis(2-propanone oxime)platinum(II)] (halido=Cl(-), Br(-), I(-)) complexes in phosphate buffer, using capillary zone electrophoresis (CZE) and CZE hyphenated to electrospray ionization-mass spectrometry (CZE-ESI-MS). The used conditions simulate those in the cytoplasm, being of importance for the activation of platinum anticancer agents for their reaction with DNA, the ultimate target. The configuration of the Pt center, i.e., cis or trans, accounts for the differing degradation kinetics of the compounds and in addition a significant influence of the halido leaving group was observed, with in case of the cis complexes pseudo first order rate constants of 0.268, 0.191 and 0.142h(-1) for Br(-), Cl(-), and I(-), respectively. Degradation of the trans isomers was significantly faster compared to their cis-configured counterparts also leading to different products which were characterized by hyphenation of CZE to ESI-MS.

Abstract
The development of cisplatin and Pt-based analogues anticancer agents requires knowledge concerning the molecular mechanisms of interaction between such drugs with DNA. However, the binding dynamics and kinetics of cisplatin reactions with DNA determined by traditional approaches are far from satisfactory. In this study, a typical 20-base oligonucleotide (CGTGACAGTTATTGCAGGCG), as a simplified model representing DNA, was mixed with cisplatin in different molar ratios and incubation time. High-resolution XPS spectra of the core elements C, N, O, P, and Cl were recorded to explore the interaction between cisplatin and DNA. From deconvoluted Cl spectra we could readily differentiate the covalently bound chlorine from ionic chloride species in the cisplatin-oligo complexes, which displayed distinct features at various reaction times and ratios. Monitoring the magnitude and energy of the photoelectron Cl 2p signal by XPS could act as a sensitive marker to probe the interaction dynamics of chemical bonds in the reaction of cisplatin with DNA. At 37°C, the optimum incubation time to obtain a stable cisplatin-oligo complex lies around 20 hrs. This novel analysis technique could have valuable implications to understand the fundamental mechanism of cisplatin cytotoxicity and determine the efficiency of the bonds in treated cancer cells.

Abstract
In recent years, capillary electrophoresis (CE) has matured to a standard method in medicinal inorganic chemistry. More and more steps of the drug discovery process are followed by CE. However, not only the number of applications has steadily increased but also the variety of used methodology has significantly broadened and, as compared to a few years ago, a wider scope of separation modes and hyphenated systems has been used. Herein, a summary of the newly utilized CE methods and their applications in metallodrug research in the timeframe 2006-2011 is presented, following related reviews from 2003 and 2007 (Electrophoresis, 2003, 24, 2023-2037; Electrophoresis 2007, 28, 3436-3446). Areas covered include impurity profiling, quality control of pharmaceutical formulations, lipophilicity estimation, interactions between metallodrugs and proteins or nucleotides, and characterization and also quantification of metabolites in biological matrices and real-world samples.

Abstract
Ruthenium-indazole complexes are promising anticancer agents undergoing clinical trials. KP1339 is administered intravenously (i.v.), where serum proteins are the first available biological binding partners. In order to gain a better insight into the mode of action, mice were treated with different doses of KP1339 i.v. and sacrificed at different time points. The blood plasma was isolated from blood samples and analyzed by capillary zone electrophoresis (CZE) and size exclusion/anion exchange chromatography (SEC-IC) both combined on-line to inductively coupled plasma-mass spectrometry (ICP-MS). The performance of the analytical methodology was compared and the interaction of KP1339 with mouse plasma proteins characterized in vivo. Interestingly, the samples of the mice treated with 50 mg kg(-1) and terminated after 24 h showed a ca. 4-fold lowered albumin content and increased ruthenation of albumin aggregates as compared to the untreated control group and the 40 mg kg(-1) group. The majority of Ru was bound to albumin and the stoichiometry of the KP1339 protein binding was determined through the molar Ru/S ratio. In general, good agreement of the data obtained with both techniques was achieved and the SEC-IC method was found to be more sensitive as compared to the CZE-ICP-MS approach, whereas the latter benefits from the shorter analysis time and lower sample consumption.

Abstract
In the last decades, the number of patients receiving chemotherapy has considerably increased. Given the toxicity of cytotoxic agents to humans (not only for patients but also for healthcare professionals), the development of reliable analytical methods to analyse these compounds became necessary. From the discovery of new substances to patient administration, all pharmaceutical fields are concerned with the analysis of cytotoxic drugs. In this review, the use of methods to analyse cytotoxic agents in various matrices, such as pharmaceutical formulations and biological and environmental samples, is discussed. Thus, an overview of reported analytical methods for the determination of the most commonly used anticancer drugs is given.

Abstract
Hydroxypyr(id)ones are versatile ligands for the synthesis of organometallic anticancer agents, equipping them with fine-tunable pharmacological properties. Herein, we report on the preparation, mode of action, and in vitro anticancer activity of Ru(II)- and Os(II)-arene complexes with alkoxycarbonylmethyl-3-hydroxy-2-pyridone ligands. The hydrolysis and binding to amino acids proceed quickly, as characterized by NMR spectroscopy and ESI mass spectrometry. However, the reaction with amino acids causes cleavage of the pyridone ligands from the metal center because the amino acids act as multidentate ligands. A similar behavior was also observed during the reactions with the model proteins ubiquitin and cytochrome c, yielding mainly [protein + M(eta(6)-p-cymene)] adducts (M = Ru, Os). Notably the ligand cleavage of the Os derivative was significantly slower than of its Ru analogue, which could explain its higher activity in in vitro anticancer assays. Furthermore, the reaction of the compounds to 5'-GMP was characterized and coordination to the N7 of the guanine moiety was demonstrated by (1)H NMR spectroscopy and X-ray diffraction analysis. CDK2/Cyclin A protein kinase inhibition studies revealed potent activity of the Ru and Os complexes.

Abstract
As part of our interest into the bioinorganic chemistry of gallium, gallium(III) complexes of the azole ligands 2,1,3-benzothiadiazole (btd), 1,2,3-benzotriazole (btaH), and 1-methyl-4,5-diphenylimidazole (L) have been isolated. Reaction of btaH or btd with GaBr3 or GaCl3 resulted in the mononuclear complexes [GaBr3(btaH)2] (1) and [GaCl3(btd)2] (2), respectively, while treatment of GaCl3 with L resulted in the anionic complex (LH)2[GaCl4] (3). All three complexes were characterized by single-crystal X-ray crystallography and IR spectroscopy, while their antiproliferative activities were investigated against a series of human and mouse cancer cell lines.

Abstract
The anticancer ruthenium-arene compound [Ru(eta(6)-C(6)H(5)CF(3))(pta)Cl(2)] (where pta is 1,3,5-triaza-7-phosphatricyclo[3.3.1.1]decane), termed RAPTA-CF3, with the electron-withdrawing alpha,alpha,alpha-trifluorotoluene ligand, is one of the most cytotoxic RAPTA compounds known. To rationalize the high observed cytotoxicity, the hydrolysis of RAPTA-CF3 in water and brine (100 mM sodium chloride) and its reactions with the protein ubiquitin and a double-stranded oligonucleotide (5'-GTATTGGCACGTA-3') were studied using NMR spectroscopy, high-resolution Fourier transform ion cyclotron resonance mass spectrometry, and gel electrophoresis. The aquation of the ruthenium-chlorido complex was accompanied by a loss of the arene ligand, independent of the chloride concentration, which is a special property of the compound not observed for other ruthenium-arene complexes with relatively stable ruthenium-arene bonds. Accordingly, the mass spectra of the biomolecule reaction mixtures contained mostly [Ru(pta)]-biomolecule adducts, whereas [Ru(pta)(arene)] adducts typical of other RAPTA compounds were not observed in the protein or DNA binding studies. Gel electrophoresis experiments revealed a significant degree of decomposition of the oligonucleotide, which was more pronounced in the case of RAPTA-CF3 compared with RAPTA-C. Consequently, facile arene loss appears to be responsible for the increased cytotoxicity of RAPTA-CF3.

Abstract
MEEKC is a powerful electrodriven separation technique with many applications in different disciplines, including medicinal chemistry; however, up to now the coupling to highly sensitive and selective MS detectors was limited due to the ion suppressive effect of the commonly used surfactant SDS. Herein, the first example of the coupling of MEEKC to ICP-MS is presented and an MEEKC method for the separation of Pt(II) and Pt(IV) anticancer drugs and drug candidates was developed. Different compositions of microemulsions were evaluated and the data were compared with those collected with standard ultraviolet/visible (UV/vis) spectroscopy detection. The MEEKC-ICP-MS system was found to be more sensitive than MEEKC-UV/vis and the analysis of UV/vis silent compounds is now achievable. The migration behavior of the Pt(II) and Pt(IV) compounds under investigation is correlated to their different chemical structures.

Abstract
The lanthanide complex aquatrichloridobis(1,10-phenanthroline)cerium(III) [Ce(phen)2(H2O)Cl3] (KP776) was fully characterized by elemental analysis, IR-, and 1H- and 13C-NMR spectroscopy, as well as TG/DTA measurements, and its behavior in H2O, important for the application as a chemotherapeutic, was studied. In addition, the binding of KP776 to nucleotides and single serum proteins was investigated by capillary electrophoresis, whereas binding to proteins in human plasma was observed by ICP-MS. The compound shows promising anticancer properties in vitro: proliferation of human cancer cell lines is strongly inhibited with IC(50) values in the very low micromolar range.

Abstract
While the metal(loid)s arsenic, bismuth, and selenium (probably also tellurium) have been shown to be enzymatically methylated in the human body, this has not yet been demonstrated for antimony, cadmium, germanium, indium, lead, mercury, thallium, and tin, although the latter elements can be biomethylated in the environment. Methylated metal(loid)s exhibit increased mobility, thus leading to a more efficient metal(loid) transport within the body and, in particular, opening chances for passing membrane barriers (blood-brain barrier, placental barrier). As a consequence human health may be affected. In this review, relevant data from the literature are compiled, and are discussed with respect to the evaluation of assumed and proven health effects caused by alkylated metal(loid) species.

Abstract
The promising drug candidate indazolium trans-[tetrachlorobis(1H-indazole)ruthenate(III)] (KP1019) is the second Ru-based anticancer agent to enter clinical trials. In this review, which is an update of a paper from 2006 (Hartinger et al., J. Inorg. Biochem. 2006, 100, 891-904), the experimental evidence for the proposed mode of action of this coordination compound is discussed, including transport into the cell via the transferrin cycle and activation by reduction. The results of the early clinical development of KP1019 are summarized in which five out of six evaluated patients experienced disease stabilization with no severe side effects.

Abstract
The application of capillary electrophoresis (CE) combined with highly sensitive inductively-coupled-plasma mass spectrometric (ICP-MS) detection allows the interactions of metal complexes with biomolecules to be characterized. This technique has been used to provide new insights into the mode of action of the ruthenium-based anticancer drug candidate indazolium [trans-tetrachlorobis(1H-indazole)ruthenate(III)] (KP1019). While the compound binds rapidly and efficiently to serum proteins, especially albumin, its reactivity towards the model DNA compound 2'-deoxyguanosine 5'-monophosphate (5'-dGMP) is moderate.

Abstract
The synthesis and in vitro anticancer activity of dihalogenido(eta6-p-cymene)(3,5,6-bicyclophosphite-alpha-D-glucofuranoside)ruthenium(II) complexes are described. The compounds were characterized by NMR spectroscopy and ESI mass spectrometry, and the molecular structures of dichlorido-, dibromido- and diiodido(eta6-p-cymene)(3,5,6-bicyclophosphite-1,2-O-isopropylidene-alpha-D-glucofuranoside)ruthenium(II) were determined by X-ray diffraction analysis. The complexes were shown to undergo aquation of the first halido ligand in aqueous solution, followed by hydrolysis of a P--O bond of the phosphite ligand, and finally formation of dinuclear species. The hydrolysis mechanism was confirmed by DFT calculations. The aquation of the complexes was markedly suppressed in 100 mM NaCl solution, and notably only very slow hydrolysis of the P--O bond was observed. The complexes showed affinity towards albumin and transferrin and monoadduct formation with 9-ethylguanine. In vitro studies revealed that the 3,5,6-bicyclophosphite-1,2-O-cyclohexylidene-alpha-D-glucofuranoside complex is the most cytotoxic compound in human cancer cell lines (IC50 values from 30 to 300 microM depending on the cell line).

Abstract
Elucidating the mode of action and thereby opening the way to the design of chemotherapeutic agents is one of the major goals of metal-based anticancer research. Hydrolysis and DNA binding play an important role for pharmaceutical formulation and for exerting anticancer activity. Herein, for the first time the application of capillary zone electrophoresis-inductively-coupled plasma mass spectrometry (CZE-ICP-MS) for studying the hydrolytic stability and the binding of the ruthenium anticancer drug candidates KP418, KP1019, and RAPTA-C to dGMP is described. RAPTA-C was found to hydrolyze fastest and showed the highest reactivity toward the DNA model compound, whereas KP418 was the most stable compound in both these respects.
