Abstract
Mitoxantrone (MTX) is an antineoplastic agent used to treat advanced breast cancer, prostate cancer, acute leukemia, lymphoma and multiple sclerosis. Although it is known to cause cumulative dose-related cardiotoxicity, the underlying mechanisms are still poorly understood. This study aims to compare the cardiotoxicity of MTX and its' pharmacologically active metabolite naphthoquinoxaline (NAPHT) in an in vitro cardiac model, human-differentiated AC16 cells, and determine the role of metabolism in the cardiotoxic effects. Concentration-dependent cytotoxicity was observed after MTX exposure, affecting mitochondrial function and lysosome uptake. On the other hand, the metabolite NAPHT only caused concentration-dependent cytotoxicity in the MTT reduction assay. When assessing the effect of different inhibitors/inducers of metabolism, it was observed that metyrapone (a cytochrome P450 inhibitor) and phenobarbital (a cytochrome P450 inducer) slightly increased MTX cytotoxicity, while 1-aminobenzotriazole (a suicide cytochrome P450 inhibitor) decreased fairly the MTX-triggered cytotoxicity in differentiated AC16 cells. When focusing in autophagy, the mTOR inhibitor rapamycin and the autophagy inhibitor 3-methyladenine exacerbated the cytotoxicity caused by MTX and NAPHT, while the autophagy blocker, chloroquine, partially reduced the cytotoxicity of MTX. In addition, we observed a decrease in p62, beclin-1, and ATG5 levels and an increase in LC3-II levels in MTX-incubated cells. In conclusion, in our in vitro model, neither metabolism nor exogenously given NAPHT are major contributors to MTX toxicity as seen by the residual influence of metabolism modulators used on the observed cytotoxicity and by NAPHT's low cytotoxicity profile. Conversely, autophagy is involved in MTX-induced cytotoxicity and MTX seems to act as an autophagy inducer, possibly through p62/LC3-II involvement.

Abstract
Background: Efficiency of both photodynamic and boron-neutron capture anticancer therapies (BNCT) depends on the properties of the used photo- and neutronsensitizer. We report on the synthesis and properties of the advanced photo- and neutronsensitizer designed as a conjugate of chlorin e6 with iron bis(dicarbollide) nanocluster. Results: The conjugate is shown to accumulate efficiently in rat glioblastoma C6 cells delivering >109 boron atoms per cell and thus meeting requirements for BNCT agents, to provide photoinduced 50% death of C6 cells at 35 ± 3 nM, to be not toxic for cells without activating stimulus. Conclusions: The conjugate is a prospective theranostic agent for photodynamic, BNCT and fluorescent diagnostics of tumors.

Abstract
Antibody microarrays have become a powerful tool in multiplexed immunoassay technologies. The advantage of microarray technology is the possibility of rapid analysis of multiple targets in a single sample with a high sensitivity, which makes them ideal for high throughput screening. Usually these microarrays contain biological recognition molecules, such as full-size antibodies, antigen-binding fragments, and single-domain antibodies, and a label for detection. Organic fluorophores are the most popular labels, but they suffer from low sensitivity and instability due to their photodegradation. Here, we describe a protocol for fabricating an antibody microarray with highly fluorescent semiconductor nanocrystals or quantum dots (QDs) as the source of fluorescent signals, which may significantly improve the properties of microarrays, including their sensitivity and specificity. Our approach to analyte detection is based on the use of sandwich approach with streptavidin-biotin to assess and monitor the fluorescence signal instead of direct labeling of samples, which helps improve the reproducibility of results and sensitivity of the microarrays. The antibody microarray developed has been tested for its capacity of detecting DNA-PKcs in glial cell lines and measuring cell protein phosphorylation changes caused by camptothecin-induced DNA damage with different protein kinase inhibitors in HeLa cells.

Abstract
The aim of this study was to investigate the cytotoxic effect of mitoxantrone on two human non-small cell lung cancer cell lines, A549 (p53+) and H1299 (p53-). To our knowledge, this is the first study to evaluate the impact of MXT on the organization of cytoskeletal proteins. Analyses were performed using fluorescence and transmission electron microscopy, spectrophotometric techniques, flow cytometry and Western blotting. It was shown that H1299 cells are significantly more sensitive to mitoxantrone than the A549 cell line, and that the growth-inhibitory effect of the drug is dose-dependent only after longer incubation. The observed presence of ring-like microtubule structures and mitochondria surrounding the nuclei of H1299 cells could be a manifestation of increased tubulin polymerization requiring large amounts of energy, whereas the loss of actin stress fibers was presumably not the cause but rather the consequence of cell death induction. Treatment with mitoxantrone also led to the appearance of structures resembling agresomes in H1299 cells and to nucleolar segregation in both cell lines. It was demonstrated that cells arrested in the S phase were most susceptible to cell death induction, and that triggered intracellular changes led mainly to apoptosis. High concentrations induced necrosis and some H1299 cells exhibited morphological features of mitotic catastrophe.

Abstract
Mitoxantrone (MTX) is an antineoplastic agent used to treat several types of cancers and on multiple sclerosis, which shows a high incidence of cardiotoxicity. Still, the underlying mechanisms of MTX cardiotoxicity are poorly understood and the potential toxicity of its metabolites scarcely investigated. Therefore, this work aimed to synthesize the MTX-naphthoquinoxaline metabolite (NAPHT) and to compare its cytotoxicity to the parent compound in 7-day differentiated H9c2 cells using pharmacological relevant concentrations (0.01-5 µM). MTX was more toxic in equivalent concentrations in all cytotoxicity tests performed [3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide reduction, neutral red uptake, and lactate dehydrogenase release assays] and times tested (24 and 48 h). Both MTX and NAPHT significantly decreased mitochondrial membrane potential in 7-day differentiated H9c2 cells after a 12-h incubation. However, energetic pathways were affected in a different manner after MTX or NAPHT incubation. ATP increased and lactate levels decreased after a 24-h incubation with MTX, whereas for the same incubation time and concentrations, NAPHT did not cause any significant effect. The increased activity of ATP synthase seems responsible for MTX-induced increases in ATP levels, as oligomycin (an inhibitor of ATP synthase) abrogated this effect on 5 µM MTX-incubated cells. 3-Methyladenine (an autophagy inhibitor) was the only molecule to give a partial protection against the cytotoxicity produced by MTX or NAPHT. To the best of our knowledge, this was the first broad study on NAPHT cardiotoxicity, and it revealed that the parent drug, MTX, caused a higher disruption in the energetic pathways in a cardiac model in vitro, whereas autophagy is involved in the toxicity of both compounds. In conclusion, NAPHT is claimed to largely contribute to MTX-anticancer properties; therefore, this metabolite should be regarded as a good option for a safer anticancer therapy since it is less cardiotoxic than MTX.

Abstract
Mitoxantrone is a synthetic anthracenedione originally developed to improve the therapeutic profile of the anthracyclines and is commonly applied in the treatment of breast and prostate cancers, lymphomas, and leukemias. A comprehensive overview of the drug's molecular, biochemical, and cellular pharmacology is presented here, beginning with the cardiotoxic nature of its predecessor doxorubicin and how these properties shaped the pharmacology of mitoxantrone itself. Although mitoxantrone is firmly established as a DNA topoisomerase II poison within mammalian cells, it is now clear that the drug interacts with a much broader range of biological macromolecules both covalently and noncovalently. Here, we consider each of these interactions in the context of their wider biological relevance to cancer therapy and highlight how they may be exploited to further enhance the therapeutic value of mitoxantrone. In doing so, it is now clear that mitoxantrone is more than just another topoisomerase II poison.

Abstract
Energy transfer from nanostructures to biological supramolecular photosystems is an important fundamental issue related to the possible influence of nanoobjects on biological functions. We demonstrate here two-photon-induced Förster resonance energy transfer (FRET) from fluorescent CdSe/ZnS quantum dots (QDs) to the photosensitive protein bacteriorhodopsin (bR) in a QD-bR hybrid material. The two-photon absorption cross section of QDs has been found to be about two orders of magnitude larger than that of bR. Therefore, highly selective two-photon excitation of QDs in QD-bR complexes is possible. Moreover, the efficiency of FRET from QDs to bR is sufficient to initiate bR photoconversion through two-photon excitation of QDs in the infrared spectral region. The data demonstrate that the effective spectral range in which the bR biological function is excited can be extended beyond the band where the protein itself utilizes light energy, which could open new ways to use this promising biotechnological material.

This work aimed to investigate the occurrence of cumulative early and late MTX-induced hepatic and haematological disturbances in an vivo model. A control group and two groups treated with three cycles of 2.5 mg/kg MTX at days 0, 10 and 20 were formed. One of the treated groups suffered euthanasia on day 22 (MTX22) to evaluate early MTX toxic effects, while the other suffered euthanasia on day 48 (MTX48), to allow the evaluation of MTX late effects. An early immunosuppression with a drop in the IgG levels was observed, causing a slight decrease in the plasma total protein content. The early bone marrow depression was followed by signs of recovery in MTX48. The genotoxic potential of MTX was demonstrated by the presence of several micronuclei in MTX22 leucocytes. Increases in plasma iron and cholesterol levels in the MTX22 rats were observed, while in both groups increases in the unconjugated bilirubin, C4 complement, and decreases in the triglycerides, alanine aminotransferase, alkaline phosphatase and transferrin were found in plasma samples. On MTX 48, the liver histology showed more hepatotoxic signs, the hepatic levels of reduced and oxidized glutathione were increased, and ATP hepatic levels were decreased. However, the hepatic total protein levels were decreased only in the livers of MTX22 group. Results demonstrated the MTX genotoxic effects, haemato- and direct hepatotoxicity. While the haematological toxicity is ameliorated with time, the same was not observed in the hepatic injury.

Abstract
HMA (5-(N,N-hexamethylene)amiloride), which belongs to a family of novel amiloride derivatives, is one of the most effective inhibitors of Na+/H+ exchangers, while uneffective against Na+ channels and Na+/Ca2+ exchangers. In this study, we provided evidence that HMA can act as a fluorescent probe. In fact, human retinal ARPE19 cells incubated with HMA show an intense bluish fluorescence in the cytoplasm when observed at microscope under conventional UV-excitation conditions. Interestingly, a prolonged observation under continuous exposure to excitation lightdoes not induce great changes in cells incubated with HMA for times up to about 5 min, while an unexpected rapid increase in fluorescence signal is observed in cells incubated for longer times. The latter phenomenon is particularly evident in the perinuclear region and in discrete spots in the cytoplasm. Since HMA modulates intracellular acidity, the dependence of its fluorescence properties on medium pH and response upon irradiation have been investigated in solution, at pH 5.0 and pH 7.2. The changes in both spectral shape and amplitude emission indicate a marked pH influence on HMA fluorescence properties, making HMA exploitable as a self biomarker of pH alterations in cell studies, in the absence of perturbations induced by the administration of other exogenous dyes.

Abstract
Mitoxantrone is an anticancer agent that acts as a topoisomerase II poison, however, it can also be activated by formaldehyde to form DNA adducts. Pixantrone, a 2-aza-anthracenedione with terminal primary amino groups in its side chains, forms formaldehyde-mediated adducts with DNA more efficiently than mitoxantrone. Molecular modeling studies indicated that extension of the "linker" region of anthracenedione side arms would allow the terminal primary amino greater flexibility and thus access to the guanine residues on the opposite DNA strand. New derivatives based on the pixantrone and mitoxantrone backbones were synthesized, and these incorporated primary amino groups as well as extended side chains. The stability of DNA adducts increased with increasing side chain length of the derivatives. A mitoxantrone derivative bearing extended side chains (7) formed the most stable adducts with ∼100-fold enhanced stability compared to mitoxantrone. This finding is of great interest because long-lived drug-DNA adducts are expected to perturb DNA-dependent functions at all stages of the cell cycle.

Abstract
P-glycoprotein (Pgp), a member of the ATP-binding cassette transporter family, is one of the major causes for multidrug resistance (MDR). We report using confocal microscopy to study the roles of Pgp in mediating the efflux of the anticancer agent mitoxantrone and the reversal of MDR by the specific Pgp inhibitor valspodar (PSC833). The net uptake and efflux of mitoxantrone and the effect of PSC833 were quantified and compared in Pgp-expressing human cancer MDA-MB-435 (MDR) cells and in parental wild-type cells. The MDR cells, transduced with the human Pgp-encoding gene MDR1 construct, were approximately 8-fold more resistant to mitoxantrone than the wild-type cells. Mitoxantrone accumulation in the MDR cells was 3-fold lower than that in the wild-type cells. The net uptake of mitoxantrone in the nuclei and cytoplasm of MDR cells was only 58 and 67% of that in the same intracellular compartment of the wild-type cells. Pretreatment with PSC833 increased the accumulation of mitoxantrone in the MDR cells to 85% of that in the wild-type cells. In living animals, the accumulation of mitoxantrone in MDA-MB-435mdr xenograft tumors was 61% of that in the wild-type tumors. Administration of PSC833 to animals before mitoxantrone treatment increased the accumulation of mitoxantrone in the MDR tumors to 94% of that in the wild-type tumors. These studies have added direct in vitro and in vivo visual information on how Pgp processes anticancer compounds and how Pgp inhibitors modulate MDR in resistant cancer cells.

Abstract
Cytochrome c is one of the key proteins involved in the programmed cell death, and lysine 72 is known to be required for its apoptogenic activity. We have engineered a number of horse and murine cytochrome c single-point mutants with various substitutions at position 72 and compared quantitatively their proapoptotic activity in living cells. Apoptosis was activated by transferring exogenous cytochrome c into the cytoplasm of cells via a nontraumatic electroporation procedure. All mutant proteins studied exhibited significantly reduced proapoptotic activities in comparison with those for the wild type cytochromes. Relative activity of the horse (h(K72X)) and murine (m(K72W)) mutant proteins diminished in the order: h(K72R) > h(K72G) > h(K72A) > h(K72E) > h(K72L) >> h(K72W) > m(K72W). As estimated, the horse and murine K72W mutants were at least 200- and 500-fold less active than corresponding wild type proteins. Thus, the K72W-substituted cytochrome c can serve as an adequate candidate for knock-in studies of cytochrome c-mediated apoptosis. The proapoptotic activity of wild-type cytochrome c from different species in murine monocytic WEHI-3 cells reduced in the order: murine cytochrome c > human cytochrome c approximately horse cytochrome c, thus indicating that apoptotic effect of cytochrome c depends on the species compatibility.

Abstract
The present work investigates the relationship between cancer cell chemosensitivity and subcellular distribution, molecular interaction, and metabolism of an anticancer drug. To get insights into this relationship, we took advantage of the differential sensitivity of two breast cancer cell lines, MDA-MB-231 and MCF-7, to anthracyclines, along with the property of docosahexaenoic acid (DHA, 22:6n-3), to differentially enhance their cytotoxic activity. The fluorescent drug mitoxantrone (MTX) was used because of the possibility to study its subcellular accumulation by confocal spectral imaging (CSI). The use of CSI allowed us to obtain semiquantitative maps of four intracellular species: nuclear MTX bound to DNA, MTX oxidative metabolite in endoplasmic reticulum, cytosolic MTX, and finally, MTX in a low polarity environment characteristic of membranes. MDA-MB-231 cells were found to be more sensitive to MTX (IC50 = 18 nM) than MCF-7 cells (IC50 = 196 nM). According to fluorescence levels, the nuclear and cytosolic MTX content was higher in MCF-7 than in MDA-MB-231 cells, indicating that mechanisms other than nuclear MTX accumulation account for chemosensitivity. In the cytosol, the relative proportion of oxidized MTX was higher in MDA-MB-231 (60%) than in MCF-7 (7%) cells. DHA sensitized MDA-MB-231 (approximately 4-fold) but not MCF-7 cells to MTX and increased MTX accumulation by 1.5-fold in MDA-MB-231 cells only. The DHA-stimulated accumulation of MTX was attributed mainly to the oxidative metabolite. Antioxidant N-acetyl-L-cysteine inhibited the DHA effect on both metabolite accumulation and cell sensitization to MTX. We conclude that drug metabolism and compartmentalization are associated with cell chemosensitization, and the related cytotoxicity mechanisms may involve oxidative stress.

Abstract
Reactive oxygen species generated by photosensitizers are efficacious remedy for tumor eradication. Eleven cycloimide derivatives of bacteriochlorin p (CIBCs) with different N-substituents at the fused imide ring and various substituents replacing the 3-acetyl group were evaluated as photosensitizers with special emphasis on structure-activity relationships. The studied CIBCs absorb light within a tissue transparency window (780-830 nm) and possess high photostability at prolonged light irradiation. The most active derivatives are 300-fold more phototoxic toward HeLa and A549 cells than the clinically used photosensitizer Photogem due to the substituents that improve intracellular accumulation (distribution ratio of 8-13) and provide efficient photoinduced singlet oxygen generation (quantum yields of 0.54-0.57). The substituents predefine selective CIBC targeting to lipid droplets, Golgi apparatus, and lysosomes or provide mixed lipid droplets and Golgi apparatus localization in cancer cells. Lipid droplets and Golgi apparatus are critically sensitive to photoinduced damage. The average lethal dose of CIBC-generated singlet oxygen per volume unit of cell was estimated to be 0.22 mM. Confocal fluorescence analysis of tissue sections of tumor-bearing mice revealed the features of tissue distribution of selected CIBCs and, in particular, their ability to accumulate in tumor nodules and surrounding connective tissues. Considering the short-range action of singlet oxygen, these properties of CIBCs are prerequisite to efficient antitumor photodynamic therapy.

Abstract
Photosensitizers 13,15-[N-(3-hydroxypropyl)]cycloimide chlorin p6 (HPC) and 13,15-(N-methoxy)cycloimide chlorin p6 methyl ester (MMC) absorb at 711 nm and possess high photoinduced cytotoxicity in vitro. Here we report, that photodynamic therapy with HPC and MMC provide considerable antitumor effect in mice bearing subcutaneous P338 lymphoma. The highest antitumor effect was achieved at a dose of 4 micromol/kg when 1.5 h delay between dye injection and light irradiation (drug-light interval) was used. According to the confocal spectral imaging studies of tissue sections this drug-light interval corresponds to a maximum of tumor accumulation of MMC and HPC (tumor to skin accumulation ratio is 8-10). Short (15 min) drug-light interval can be used for efficient vasculature-targeted photodynamic therapy with HPC at a dose of 1 micromol/kg, whereas MMC is ineffective at the short drug-light interval. Relationships between the features of tissue distribution and efficacy of photodynamic therapy at different drug-light intervals are discussed for HPC and MMC.

Abstract
Cytotoxins from cobra venom are known to manifest cytotoxicity in various cell types. It is widely accepted that the plasma membrane is a target of cytotoxins, but the mechanism of their action remains obscure. Using the confocal spectral imaging technique, we show for the first time that cytotoxins from cobra venom penetrate readily into living cancer cells and accumulate markedly in lysosomes. Cytotoxins CT1 and CT2 from Naja oxiana, CT3 from Naja kaouthia and CT1 from Naja haje are demonstrated to possess this property with respect to human lung adenocarcinoma A549 and promyelocytic leukaemia HL60 cells. Immobilized plasma membrane binding accompanies the internalization of CT3 from Naja kaouthia in the HL60 cells, but it is very weak for other cytotoxins. Detectable membrane binding is not a property of any of the cytotoxins tested in A549 cells. The kinetics and concentration-dependence of cytotoxin accumulation in lysosomes correlate well with their cytotoxic effects. On the basis of the results obtained, we propose that lysosomes are a primary target of the lytic action of cytotoxins. Plasma membrane permeabilization seems to be a downstream event relative to lysosome rupture. Direct damage to the plasma membrane may be a complementary mechanism, but its relative contribution to the cytotoxic action depends on the cytotoxin structure and cell type.

Abstract
A non-traumatic electroporation procedure was developed to load exogenous cytochrome c into the cytoplasm and to study the apoptotic effect of cytochrome c, its K72-substitued mutants and "yeast --> horse" hybrid cytochrome c in living WEHI-3 cells. The minimum apoptosis-activating intracellular concentration of horse heart cytochrome c was estimated to be 2.7 +/- 0.5 microM (47 +/- 9 fg/cell). The equieffective concentrations of the K72A-, K72E- and K72L-substituted mutants of cytochrome c were five-, 15- and 70-fold higher. The "yeast --> horse" hybrid created by introducing S2D, K4E, A7K, T8K, and K11V substitutions (horse protein numbering) and deleting five N-terminal residues in yeast cytochrome c did not evoke apoptotic activity in mammalian cells. The apoptotic function of cytochrome c was abolished by the K72W substitution. The K72W-substituted cytochrome c possesses reduced affinity to the apoptotic protease activating factor-1 (Apaf-1) and forms an inactive complex. This mutant is competent as a respiratory-chain electron carrier and well suited for knock-in studies of cytochrome c-mediated apoptosis.

Comparative study of 13,15-[N-(2-hydroxyethyl)]cycloimide chlorin p6 (2), 13,15-(N-acetoxy)cycloimide chlorin p6 (3), 13,15-(N-hydroxy)cycloimide chlorin p6 methyl ester (4) and 13,15-(N-methoxy)cycloimide chlorin p6 methyl ester (5) together with the previously investigated 13,15-[N-(3-hydroxypropyl)]cycloimide chlorin p6 (1) was performed. The dependence of the key photodynamic properties of 1-5 on the introduced substituents was analyzed. The photoinduced cell-killing activity of 4 is 100- and 280-fold higher than that of chlorin p6 and Photogem, respectively, as estimated on A549 human lung adenocarcinoma cells. The activity is reduced eight times in the order 4 > 5 > 1 > 2 > 3. The intracellular accumulation of 1-5 occurs in cytoplasm in a monomeric form bound to the lipids of cellular membranes. This form of 1, 2, 3, 4 and 5 is characterized by the high quantum yield of singlet oxygen generation, which depends on the introduced substituents, 0.66, 0.59, 0.35, 0.51 and 0.73, respectively. The photostability is two-fold less for 1 and four-fold less for 2, 3 and 5 than for 4. The rates of cellular uptake and efflux of 1-5 vary widely, thus providing the way to optimize the pharmacological properties of the photosensitizer (PS) using the respective substituents. Modifying the substituents, 1-5 were targeted to different cellular organelles. The enhanced accumulation in the Golgi apparatus and mitochondria complemented with diffuse staining of intracellular membranous structures is a property of 1-4. Compound 5 accumulates selectively in the lipid droplets and stains weakly perinuclear structures. Temperature-sensitive mechanisms of transport are responsible for the 1-4 uptake. Diffusion can play a role in the internalization of 5 but not of 1-4. Endocytosis via caveolae, clathrin-dependent and adenosine triphosphate-dependent pathways are not noticeably involved in the 1-5 internalization. Independently from their intracellular localization 1, 4 and 5 are highly efficient near-IR PS, which induce predominantly an apoptotic type of cell death under conditions providing ca 50% level of phototoxicity and necrosis at the 100% level of phototoxicity.

Abstract
Sensitivity of human fibroblasts derived from Down's syndrome (DS) individuals (S-240, T-158, T-74, T-164) and normal donors (S-126, WA-1) to anticancer antibiotic-mitoxantrone (1,4-dihydroxy-5,8-bis((2-((2-hydroxy-ethyl)amino)ethyl)amino)-9,10-anthracenedione dihydrochloride; MIT) and its relationship to the transport rate, cellular distribution and interaction with cell membrane were studied. The survival assay showed that MIT was more toxic to trisomic fibroblast lines than to normal cells. Studies of transport kinetics indicated that the amount of drug taken up and extruded by DS cells was diminished, compared to control cells. In contrast, the cellular level of MIT associated with DNA was greater in trisomic than in normal cells. The fluorescence anisotropy measurements of TMA-DPH and 12-AS demonstrated that the fluidity of the polar region of the outer lipid monolayer of DS cell membrane was decreased in comparison with normal cells. MIT treatment decreased fluidity of the inner hydrophobic region of plasma membrane, but only slightly influenced the fluidity of the outer surface of the cell membrane. Finally, we concluded that lowered membrane fluidity, diminished amount of MIT extruded by cells and the enhanced level of the drug associated with DNA could be responsible for the enhanced sensitivity of DS fibroblasts to the MIT treatment.

Abstract
Six water-soluble macrocyclic photosensitizers, the members of two groups of expanded porphyrins (metallotexaphyrins and free-base sapphyrins) containing hydrophilic substituents and meso-tetra(4-sulfonatophenyl)-porphyrin, were tested by UV-Vis absorption and resonance Raman spectroscopy in the in vitro binding experiments with intact mitochondria isolated from swine liver. Studied macrocycles showed markedly different affinity to mitochondria. The highest uptake was observed for sapphyrin-sugar conjugate and metallotexaphyrins. Sapphyrin-polyamine conjugates exhibit something less affinity to mitochondria, while the porphyrin of anionic character showed very low mitochondrial uptake. Obtained spectroscopic results confirm that the binding process altered the self-aggregation degree of expanded porphyrins.

Abstract
Fluorescein labeled carbohydrate (Glyc) probes were synthesized as analytical tools for the study of cellular lectins, i.e. SiaLe(x)-PAA-flu, Sia2-PAA-flu, GlcNAc2-PAA-flu, LacNAc-PAA-flu and a number of similar ones, with PAA a soluble polyacrylamide carrier. The binding of SiaLe(x)-PAA-flu was assessed using CHO cells transfected with E-selectin, and the binding of Sia2-PAA-flu was assessed by COS cells transfected with siglec-9. In flow cytometry assays, the fluorescein probes demonstrated a specific binding to the lectin-transfected cells that was inhibited by unlabeled carbohydrate ligands. The intense binding of SiaLe(x)-PAA-3H to the E-selectin transfected cells and the lack of binding to both native and permeabilized control cells lead to the conclusion that the polyacrylamide carrier itself and the spacer arm connecting the carbohydrate moiety with PAA did not contribute anymore to the binding. Tumors were obtained from nude mice by injection of CHO E-selectin or mock transfected cells. The fluorescent SiaLe(x)-PAA-flu probe could bind to the tumor sections from E-selectin positive CHO cells, but not from the control ones. Thus, these probes can be used to reveal specifically the carbohydrate binding sites on cells in culture as well as cells in tissue sections. The use of the confocal spectral imaging technique with Glyc-PAA-flu probes offered the unique possibility to detect lectins in different cells, even when the level of lectin expression was rather low. The confocal mode of spectrum recording provided an analysis of the probe localization with 3D submicron resolution. The spectral analysis (as a constituent part of the confocal spectral imaging technique) enabled interfering signals of the probe and intrinsic cellular fluorescence to be accurately separated, the distribution of the probe to be revealed and its local concentration to be measured.

Abstract
Recently, we have shown that mitoxantrone can be activated by formaldehyde in vitro to form DNA adducts that are specific for CpG and CpA sites in DNA. The CpG specificity of adduct formation prompted investigations into the effect of cytosine methylation (CpG) on adduct formation, since the majority of CpG dinucleotides in the mammalian genome are methylated and hypermethylation in subsets of genes is associated with various neoplasms. Upon methylation of a 512-base pair DNA fragment (containing the lac UV5 promoter) using HpaII methylase, three CCGG sites downstream of the promoter were methylated at C5 of the internal cytosine residue. In vitro transcription studies of mitoxantrone-reacted DNA revealed a 3-fold enhancement in transcriptional blockage (and hence adduct formation) exclusively at these methylated sites. In vitro cross-linking assays also revealed that methylation enhanced mitoxantrone adduct formation by 2-3-fold, and methylation of cytosine at a single potential drug binding site on a duplex oligonucleotide also enhanced adduct levels by 3-fold. Collectively, these results indicate preferential adduct formation at methylated CpG sites. However, adducts at these methylated sites exhibited the same stability as nonmethylated sites, suggesting that cytosine methylation increases drug accessibility to DNA rather than being involved in kinetic stabilization of the adduct.

Abstract
Molecular in vitro and in vivo properties of 3-devinyl-3-formylchlorin p6 (FCp6) were examined in order to characterize this derivative as a new prospective photosensitizer. The long-wavelength absorption maximum of FCp6 was 690-696 nm (depending on environment). FCp6 was found to bind readily to membranous structures and form complexes with some proteins. The dye was associated with the plasmalemma and distributed rather diffusely along the cytoplasm with ca a three-fold higher accumulation within mitochondria in A549 human adenocarcinoma cells. The spectral analysis revealed that the major part of FCp6 was bound to membranes within cells. The membrane-bound FCp6 was shown to generate singlet oxygen efficiently. The average cytoplasmic concentration of FCp6 in A549 cells achieved ca 80% of its extracellular concentration in complete medium. The dye was characterized by a very fast efflux (16-fold decrease in 2 h). The ex vivo analysis of FCp6 fluorescence in mice revealed that the maximal dye content in blood, tissues, organs and tumor was achieved in less than 1 h after injection, followed by a considerable (ca six-fold) decrease during the next 23 h and a long-term persistence at low level. A preferential accumulation of FCp6 in subcutaneously implanted Ehrlich carcinoma along with its higher retention level comparing to the surrounding skin and muscles were observed in mice treated with different dye doses. In vitro cytotoxic assays with A549 and Raji B-cell lymphoma cells as well as in vivo analyses using Ehrlich carcinoma in mice revealed the very low toxicity of FCp6 without light irradiation and the significant photodynamic activity of this compound.

Abstract
Recently we have found that mitoxantrone, like Adria-mycin, can be activated by formaldehyde and subsequently form adducts which stabilise double-stranded DNA in vitro. This activation by formaldehyde may be biologically relevant since formaldehyde levels are elevated in those tumours in which mitoxan-trone is most cytotoxic. In vitro transcription analysis revealed that these adducts block the progression of RNA polymerase during transcription and cause truncated RNA transcripts. There was an absolute requirement for both mitoxantrone and formaldehyde in transcriptional blockage formation and the activated complex was found to exhibit site specificity, with blockage occurring prior to CpG and CpA sites in the DNA (non-template strand). The stability of the adduct at 37 degrees C was site dependent. The half-lives ranged from 45 min to approximately 5 h and this was dependent on both the central 2 bp blockage site as well as flanking sequences. The CpG specificity of mitoxantrone adduct sites was also confirmed independently by a lambda exonuclease digestion assay.

Abstract
Binary systems combining a transition metal complex and ascorbate have been proposed recently for catalytic therapy of malignant tumors. The killing effect on tumor cells is achieved by production of free radicals in the course of accelerated oxidation of ascorbate by dioxygen in the presence of transition metal complexes. Further progress in the development of binary catalytic systems (BCSs) requires a special method for their investigation in cells and tissues, because neither component of BCSs fluoresces. Here a resonance Raman confocal spectral imaging (RR CSI) technique was introduced as a unique approach to monitor quantitatively the transition metal complexes within living cells. Intracellular accumulation, localization, and retention of theraphthal (TP), a catalyst of the advanced TP/ascorbate BCS, were investigated in A549 cells with the RR CSI technique. The cellular analysis was complemented with the detailed study of molecular interactions of TP in solution and environmental factors affecting the RR spectrum of TP. TP does not penetrate into membranes, it binds very weakly to DNA and RNA, but it readily forms complexes with proteins. Binding with Ca(2+) cations and decreasing pH below 6 induce aggregation of TP. By analyzing RR spectra recorded from every point within a TP-treated cell, three states of the agent were discriminated, namely, monomeric TP in polar environment, TP bound to proteins, and aggregated TP. Their cytoplasmic and nuclear distributions were mapped at different stages of uptake and efflux. By introducing organelle-selective fluorescent probes into drug-treated cells and measuring intracellular localization of both the probe and the drug, compartmentation of TP was revealed. Cell growth suppression by the TP/ascorbate system was measured, and probable molecular and organelle targets of radical damage were characterized.
