Abstract
Among bisnaphthalimidopropyl (BNIP) derivatives, BNIPDaoct and BNIPDanon recently came forward with antileishmanial activities beyond the standard, commercialized antileishmanial therapies. However, high-level toxicity on macrophages plus poor aqueous solubility and poor bioavailability of the compounds limit their application in therapies. Addressing these limitations, the present study introduces BNIPDaoct- and BNIPDanon-loaded emulsomes as lipid-based nanocarrier systems. Accordingly, emulsome formulations were prepared with the presence of BNIP compounds. The average diameters of BNIPDaoct- and BNIPDanon-loaded emulsomes were found as 363.1 and 337.4 nm, respectively; while empty emulsomes differed with a smaller average particle diameter, i.e., 239.1 nm. All formulations exhibited a negative zeta potential value. The formulations achieved the encapsulation of BNIPDaoct and BNIPDanon at approximately 0.31 mg/ml (501 µM) and 0.24 mg/ml (387 µM), respectively. The delivery of BNIP within the emulsomes improved the antileishmanial activity of the compounds. BNIPDaoct-loaded emulsome with 50% inhibitory concentration (IC50) value of 0.59 ± 0.08 µM was in particular effective against Leishmania infantum promastigotes compared to free BNIPDaoct (0.84 ± 0.09 µM), free BNIPDanon (1.85 ± 0.01 µM), and BNIPDanon-loaded emulsome (1.73 ± 0.02 µM). Indicated by at least ≥ 2-fold higher 50% cytotoxic concentration (CC50) values, the incorporation of BNIP into emulsomes significantly reduced the toxicity of BNIPs against macrophages, corresponding to up to 16-fold improvement in selectivity index (CC50/IC50) for L. infantum promastigotes. The infection rates of macrophages were determined using dual-fluorescent flow cytometry as 68.6%. Both BNIP formulations at concentration of 1.87 µM reduced the parasitic load nearly to 40%, whereas BNIPDaoct-loaded emulosmes could further decrease the parasitic load below 20% at 7.5 µM and above. In conclusion, the incorporation of BNIPDaoct and BNIPDanon into emulsomes results in water-soluble dispersed emulsome formulations that do not only successfully facilitate the delivery of BNIP compounds into the parasites and the Leishmania-infected macrophages in vitro but also enhance antileishmanial efficacy as proven by the decline in IC50 values. The selectivity of the formulation for L. infantum parasites further contributes to the challenging safety profile of the compounds. The promising in vitro antileishmanial efficacy of BNIP-loaded emulsomes highlights the potential of the system for the future in vivo studies.

Abstract
This review intends to summarize the structures of an extensive number of symmetrical-dimeric drugs, having two monomers linked via a bridging entity while emphasizing the large versatility of biologically active substances reported to possess dimeric structures. The largest number of classes of these compounds consist of anticancer agents, antibiotics/antimicrobials, and anti-AIDS drugs. Other symmetrical-dimeric drugs include antidiabetics, antidepressants, analgesics, anti-inflammatories, drugs for the treatment of Alzheimer's disease, anticholesterolemics, estrogenics, antioxidants, enzyme inhibitors, anti-Parkisonians, laxatives, antiallergy compounds, cannabinoids, etc. Most of the articles reviewed do not compare the activity/potency of the dimers to that of their corresponding monomers. Only in limited cases, various suggestions have been made to justify unexpected higher activity of the dimers vs. the corresponding monomers. These suggestions include statistical effects, the presence of dimeric receptors, binding of a dimer to two receptors simultaneously, and others. It is virtually impossible to predict which dimers will be preferable to their respective monomers, or which linking bridges will lead to the most active compounds. It is expected that the extensive number of articles summarized, and the large variety of substances mentioned, which display various biological activities, should be of interest to many academic and industrial medicinal chemists.

Abstract
Cancer is the uncontrolled growth of abnormal cells via malignant cell division and rapid DNA replication. While DNA damaging molecules can cause cancer, their role as anticancer drugs are very significant. For this purpose, the novel series of paraben substituted spermine bridged(dispirobino) cyclotriphosphazene compounds 2-6 were synthesized for the first time, and their structures were characterized by various spectroscopic techniques. The solid-state structures and geometries of compounds 2-6 were determined using single-crystal X-ray structural analysis. In addition, it was confirmed by TGA that all compounds 1-6 showed high thermal stability. Two methods were used in order to investigate DNA interaction properties of the targeted molecules. While biosensor-based screening test that measures DNA hybridization efficiency on a biochip surface, the agarose gel electrophoresis method examines the effect of compounds on plasmid DNA structure. The results collected from the automated biosensor device and agarose gel electrophoresis have indicated that compounds 1, 5, and 6 showed higher DNA damage than the compounds 2-4. According to the biosensor results, compounds 1, 5, and 6 showed 85%, 69%, and 77% activity, respectively.

Abstract
Bisnaphthalimides are DNA intercalators of potential use as chemotherapeutics but for which the range of mechanism of action is only gradually being elucidated. Using human promyelocytic HL-60 cells, we extend characterization of the cytotoxicity of bisnaphthalimidopropylspermidine (BNIPSpd) and examine the relationship with caspase-activity. Within 4 h exposure, BNIPSpd (1-10 μM) induced significant DNA strand breakage. Evidence of apoptosis was progressive through the experimental period. Within 6 h, BNIPSpd increased the proportion of cells exhibiting plasma membrane phosphatidylserine exposure. Within 12 h, active caspase expression increased and was sustained with 5 and 10 μM BNIPSpd. Flow cytometric analysis revealed caspase activity in cells with and without damaged membranes. By 24 h, 5 and 10 μM BNIPSpd increased hypodiploid DNA content and internucleosomal DNA fragmentation (DNA ladders) typical of the later stages of apoptosis. 1 μM BNIPSpd exposure also increased hypodiploid DNA content by 48 h. Polyamine levels decreased by 24 h BNIPSpd exposure. The pan-caspase inhibitor, z-VAD-fmk, significantly decreased DNA degradation (hypodiploid DNA and DNA ladders) and cytotoxicity. Despite this, cell growth and viability remained significantly impaired. We propose that BNIPSpd cytotoxicity arises through DNA damage and not polyamine depletion and that cytotoxicity is dominated by but not dependent upon caspase driven apoptosis.

Abstract
Bisnaphthalimidopropyl (BNIP) derivatives are a family of compounds that exert anti-cancer activities in vitro and, according to previous studies, variations in the linker sequence have increased their DNA binding and cytotoxic activities. By modifying the linker sequence of bisnaphthalimidopropyl diaminodicyclohexylmethane (BNIPDaCHM), a previously synthesised BNIP derivative with anti-cancer properties, three novel BNIP derivatives were designed. Bisnaphthalimidopropyl-piperidylpropane (BNIPPiProp), a structural isomer of BNIPDaCHM, bisnaphthalimidopropyl ethylenedipiperidine dihydrobromide (BNIPPiEth), an isoform of BNIPDaCHM with a shorter linker chain, and (trans(trans))-bisnaphthalimidopropyl diaminodicyclohexylmethane (trans,trans-BNIPDaCHM), a stereoisomer of BNIPDaCHM, were successfully synthesised (72.3-29.5% yield) and characterised by nuclear magnetic resonance spectroscopy (NMR) and mass spectrometry (MS). Competitive displacement of ethidium bromide (EtBr) and UV binding studies were used to study the interactions of BNIP derivatives with Calf Thymus DNA. The cytotoxicity of these derivatives was assessed against human breast cancer MDA-MB-231 and SKBR-3 cells by MTT assay. Propidium iodide (PI) flow cytometry was conducted in order to evaluate the cellular DNA content in both breast cancer cell lines before and after treatment with BNIPs. The results showed that all novel BNIPs exhibit strong DNA binding properties in vitro, and strong cytotoxicity, with IC50 values in the range of 0.2-3.3 μM after 24 hours drug treatment. Two of the novel BNIP derivatives, BNIPPiEth and trans,trans-BNIPDaCHM, exhibited greater cytotoxicity against the two breast cancer cell lines studied, compared to BNIPDaCHM. By synthesising enantiopures and reducing the length of the linker sequence, the cytotoxicity of the BNIP derivatives was significantly improved compared to BNIPDaCHM, while maintaining DNA binding and bis-intercalating properties. In addition, cell cycle studies indicated that trans,trans-BNIPDaCHM, the most cytotoxic BNIP derivative, induced sub-G1 cell cycle arrest, indicative of apoptotic cell death. Based on these findings, further investigation is under way to assess the potential efficacy of trans,trans-BNIPDaCHM and BNIPPiEth in treating human breast cancer.

Abstract
A series of bis-naphthalimide derivatives with different diamine linkers were designed and synthesized. All of the synthesized bis-naphthalimide derivatives were characterized by NMR and HRMS spectra. The binding ability between the compounds and CT DNA was evaluated by using UV-Vis titration experiments. The bis-naphthalimide compound with an ethylenediamine linker showed the largest binding constant with CT DNA. Hence, it was used as the model compound to study the DNA binding selectivity by UV-Vis titration aiming at different DNA duplexes. As a result, this compound showed binding preference to AT-rich duplexes. The DNA binding modes of the compounds were also measured by viscosity titration. The cytotoxicity of the compounds was evaluated by MTT assay. Compounds with 1,6-diaminohexane or 1,4-phenylenedimethanamine linkers showed higher cytotoxicity compared with other bis-naphthalimide derivatives.

Abstract
The interaction of a polyazacyclophane ligand having an ethylamine pendant arm functionalized with an anthryl group (L), with the single-stranded polynucleotides polyA, polyG, polyU, and polyC as well as with the double-stranded polynucleotides polyA-polyU, poly(dAT)2 , and poly(dGC)2 has been followed by UV/Vis titration, steady state fluorescence spectroscopy, and thermal denaturation measurements. In the case of the single-stranded polynucleotides, the UV/Vis and fluorescence titrations permit to distinguish between sequences containing purine and pyrimidine bases. For the double-stranded polynucleotides the UV/Vis measurements show for all of them hypochromicity and bathochromic shifts. However, the fluorescence studies reveal that both polyA-polyU and poly(dAT)2 induce a twofold increase in the fluorescence, whereas interaction of poly(dGC)2 with the ligand L induces a quenching of the fluorescence. Cu2+ modulates the interaction with the double-stranded polynucleotides due to the conformation changes that its coordination induces in compound L. In general, the spectroscopic studies show that intercalation seems to be blocked by the formation of the metal complex. All these features suggest the possibility of using compound L as a sequence-selective fluorescence probe.

Abstract
New oxoazabenzo[de]anthracenes derivatives were synthesised and characterised. Their interactions with calf thymus DNA were studied by UV spectrophotometric analysis and a competitive ethidium bromide displacement assay. Cytotoxicity was determined by MTT assay, against colon adenocarcinoma (Caco-2 cells). Among all the oxoazabenzo[de]anthracenes derivatives reported herein only the piperidino derivative exhibited strong DNA binding properties and cytotoxic activity with IC₅₀ values in the range of 16 ± 1.5 μM (72-h treatment). In addition, the piperidino derivative did not directly inhibit topoisomerase I and topoisomerase II enzymes. The results confirm that the presence of the oxoazabenzo[de]anthracenes together with the piperidino functionality is crucial in exerting DNA binding and cytotoxic properties, hence demonstrating promise as a chemical scaffold for further development of new anticancer agents.

Abstract
Chemotherapy is still the most important method of cancer treatment. To make this method more effective and safe, new drugs to destroy cancer cells are needed. Some bis-naphthalimide derivatives show potential anticancer activity via an intercalation mechanism. A higher degree of DNA intercalation corresponds to better therapeutic effects. The degree of intercalation of naphthalimides depends on their structure, molecular dynamics and intermolecular interactions with DNA. In order to apply any active substance as a drug, its molecular dynamics as well as possible interactions with target molecules have to be examined in exhaustive details. This paper describes a practical preparation of some novel bis-naphthalimide derivatives with different functional groups and their FTIR and ¹H- and ¹³C-NMR spectral characteristics. To determine the molecular dynamics of the obtained compounds the temperature, their ¹H-NMR spectra were measured. It has been clearly proven in this paper that the unusual temperature-dependent ¹H-NMR behavior of the aromatic protons of phthalimide derivatives, previously described in the literature as "hypersensitivity" and explained by n-π interactions and molecular motions of aromatic amide rings, is a result of temperature driven changes of the geometry of carbonyl groups.

Abstract
Mygalin is an antibacterial molecule isolated from the hemocytes of the spider Acanthoscurria gomesiana. It was identified as bis-acylpolyamine spermidine. We evaluated the modulator effects of synthetic Mygalin in the innate immune response. We demonstrate that Mygalin induces IFN-γ synthesis by splenocytes increasing the nitrite secretion by splenocytes and macrophages. A specific inhibitor of iNOS abrogated Mygalin-induced nitrite production in macrophages independent of IFN-γ activation. In addition, Mygalin-activated macrophages produced TNF-α but not IL-1β, demonstrating that Mygalin does not act directly on the inflammasome. Furthermore, this compound did not affect spontaneous or Concanavalin A-induced proliferative responses by murine splenocytes and did not induce IL-5 or apoptosis of splenocytes or bone marrow-derived macrophages. These data provide evidence that Mygalin modulates the innate immune response by inducing IFN-γ and NO synthesis. The combined immune regulatory and antibacterial qualities of Mygalin should be explored as a strategy to enhance immune responses in infection.

Abstract
The synthesis and DNA binding properties of a bis-naphthyl imide tetracationic diviologen compound NI(CH2)3V(2+)(CH2)6V(2+)(CH2)3NI (where V(2+) = 4,4'-bipyridinium and NI = naphthyl imide, NIV) are described. Binding to thiolated ssDNA and dsDNA immobilized at Au electrodes was characterized using the electrochemical response for reduction of the V(2+) state to the V+ (viologen radical cation) state. Isotherms and binding constants for this molecule to both forms of immobilized DNA were generated in this fashion. The character of the binding isotherm for dsDNA suggests bis-intercalation. Under high saline conditions, the diviologen molecule dissociated 160 times slower from dsDNA compared to ssDNA. Slow dissociation kinetics from dsDNA (kd =7.0 x 10-5 s(-1)) allow this molecule to be used as an effective DNA hybridization indicator.

Abstract
The good results obtained in the past decade with various types of potential bisintercalating agents, e.g., LU 79553, DMP 840, BisBFI, MCI3335, WMC-26, BisAC, BisPA, and the asymmetrical derivative WMC-79 (Chart 1), prompted us to investigate a new series of asymmetrical bisintercalators, compounds 1a-t (Chart 2), which can combine the potentiality of bisintercalation with a possible different mechanism of action due to two diverse chromophores. The DNA-binding properties of these compounds have been examined using fluorometric techniques: target compounds are excellent DNA ligands, with a clear preference for binding to AT-rich duplexes. In vitro cytotoxicity of these derivatives toward human hormone-refractory prostate adenocarcinoma cell line (PC-3) is described. Apoptosis assays of four selected compounds are also reported. Very potent cytotoxic compounds, some of them capable of inducing early apoptosis, have been identified.

Abstract
A series of 2,6-diphenylpyrazine derivatives was synthesized from 2,6-dichloropyrazine and 4-methoxyphenylboronic acid using palladium(0) as catalyst in a Suzuki methodology. After deprotection of the hydroxyl, alkylation reactions with different halides afforded compounds 5-8 bearing hydrophilic chains. DNA binding and cytotoxic properties were investigated. Compound 11 bearing imidazoline terminal groups was found to be a potent AT-specific DNA minor groove binder but there was no relationship between DNA interaction and cytotoxicity. However, in all cases the incorporation of the pyrazine ring was found to promote the cytotoxicity of the molecules compared to the corresponding pyridine analogues, previously synthesized.

Abstract
A series of 2,5- and 3,5-diphenylpyridine derivatives was synthetised in high yields. A versatile chemical strategy allows the design of diphenylpyridines differently substituted with cationic or neutral side chains. The interaction of the molecules with DNA was investigated by biophysical and biochemical methods and an AT-binder (20) was characterised. A few cytotoxic molecules were identified but their antiproliferative activity does not correlate with DNA binding. Two compounds 18 and 22 showed significant antiproliferative activity and provide a novel route to potential anticancer agents.

Abstract
We report the synthesis of an original series of oxoazabenzo[de]anthracenes conjugated to an amino acid: Ala, Phe, Pro, Lys, or Gly (4a-e, respectively). The compounds, derived from 1,8-dihydroxyanthracene-9,10-dione, were studied for DNA binding and cytotoxicity. Melting temperature, fluorescence quenching, and surface plasmon resonance methods all indicated that the lysine derivative 4d binds to DNA much more strongly that the Pro, Ala, and Gly conjugates whereas the Phe analogue showed the lowest DNA binding capacity. These compounds form intercalation complexes with DNA, as judged from electric linear dichroism and topoisomerase I-based DNA unwinding experiments. Preferential binding of 4d to defined sequences such as 5'-CTAAAGG and 5'-ATGC was evidenced by DNase I footprinting. This Lys conjugate was found to be over 20 times more cytotoxic to CEM human leukemia cells than the other conjugates, with an IC50 in the submicromolar range. A high antiproliferative activity, likely attributable to the enhanced DNA binding capacity, is maintained despite the incapacity of the compound to stabilize topoisomerase-DNA covalent complexes. The cell cycle effects of 4d consisted in an S phase accumulation of cells coupled with a pro-apoptotic action (appearance of hypodiploid sub-G1 cells) which were confirmed by measuring the inhibition of BrdU incorporation into DNA and labeling of phosphatidylserine residues with annexin V-FITC by means of flow cytometry. Altogether, the work provides interesting structure-activity relationships in the oxoazabenzo[de]anthracene-amino acid conjugate series and identifies the lysine derivative 4d as a promising candidate for further in vivo evaluation and drug design.

Immunological alterations induced by polyamine derivatives on murine splenocytes and human mononuclear cells. Int Immunopharmacol 2005; 4:547-56.

Abstract
Three polyamine derivatives assigned as bis-naphthalimidopropyl putrescine (BNIPPut), spermidine (BNIPSpd) and spermine (BNIPSpm) were studied to determine their effects on the proliferation of murine splenocytes and human peripheral blood mononuclear cells (PBMC) induced by the mitogens, Con A, LPS and PHA. All compounds showed a dose dependent inhibitory effect on mouse and human T cell proliferation induced by the mitogens, with BNIPPut exhibiting the most potent antiproliferative activity, followed by BNIPSpd and by BNIPSpm, respectively (Put > Spd > Spm), when considering human T cells. This suppressive activity also affects the capacity of mouse spleen cells to produce Th1 cytokines, namely IL-2 and INF-gamma after in vitro stimulation with Con A. The polyamine-induced inhibition also occurred in the case of LPS-stimulated B cells with a marked decrease of CD69 expression by these cells. Furthermore, the ability for these polyamine derivatives to induce apoptosis on Con A-stimulated splenocytes could be related to their antiproliferative activity.

Abstract
The natural polyamines are ubiquitous polycationic compounds that play important biological functions in cell growth and differentiation. In the case of protozoan species that are causative agents of important human diseases such as Leishmaniasis, an exogenous supply of polyamines supports parasite proliferation. In the present study, we have investigated the effect of three polyamine derivatives, (namely bis-naphthalimidopropyl putrescine (BNIPPut), spermidine (BNIPSpd) and spermine (BNIPSpm)), on the proliferative stages of Leishmania infantum, the causative agent of visceral leishmaniasis in the Mediterranean basin. A significant reduction of promastigotes and axenic amastigotes growth was observed in the presence of increasing concentrations of the drugs, although the mechanisms leading to the parasite growth arrest seems to be different. Indeed, by using a number of biochemical approaches to analyse the alterations that occurred during early stages of parasite-drug interaction (i.e. membrane phosphatidylserine exposure measured by annexin V binding, DNA fragmentation, deoxynucleotidyltranferase-mediated dUTP end labelin (TUNEL), mitochondrial transmembrane potential loss), we showed that the drugs had the capacity to induce the death of promastigotes by a mechanism that shares many features with metazoan apoptosis. Surprisingly, the amastigotes did not behave in a similar way to promastigotes. The drug inhibitory effect on amastigotes growth and the absence of propidium iodide labelling may suggest that the compounds are acting as cytostatic substances. Although, the mechanisms of action of these compounds have yet to be elucidated, the above data show for the first time that polyamine derivatives may act differentially on the Leishmania parasite stages. Further chemical modifications are needed to make the polyamine derivatives as well as other analogues able to target the amastigote stage of the parasite.

Abstract
New bisoxynaphthalimidopolyamines (BNIPOPut, BNIPOSpd and BNIPOSpm) were synthesized. Their cytotoxic properties were evaluated against breast cancer MCF 7 cells and compared with bisnaphthalimidopolyamines BNIPSpd and BNIPSpm. Among the bisoxynaphthalimido polyamines, BNIPOSpm and BNIPOSpd exhibited cytotoxic activity with an IC50 f 29.55 and 27.22 microM, respectively, while BNIPOPut failed to exert significant cytotoxicity after 48-h drug exposure. DNA binding was determined by midpoint of thermal denaturation (Tm) measurement, ethidium bromide displacement and DNA gel mobility. Both BNIPOSpm and BNIPOSpd exhibited strong binding affinities with DNA. BNIPOPut had the least effect. The results were compared with other cytotoxic bisnaphthalimido compounds (BNIPSpm and BNIPSpd) previously reported by us. Using the single cell gel electrophoresis assay, it was found that BNIPSpm and BNIPSpd caused substantial DNA damage to MCF 7 treated cells while BNIPOSpm showed no significant effect over a range of drug concentrations after 4-h drug exposure. However, after 12-h drug exposure, BNIPOSpm had induced significant DNA damage similar to that of BNIPSpm (after 4-h drug exposure). Fluorescence microscopic analysis revealed that at 1 microM drug concentration and after 6-h drug exposure, both BNIPSpm and BNIPSpd were located within the cell while the presence of BNIPOSpm, was not observed. Therefore, we conclude that BNIPSpd, BNIPSpm and BNIPOSpm induce DNA damage consistent with their rate of uptake into the cells.

Abstract
The tetrahydroindeno[1,2-b]pyrido[4,3,2-de]quinoline chromophore was initially designed as a DNA intercalating unit because of its planar structure. Unexpectedly, one molecule (15d) bearing two N-methylpiperazine chains on both sides of this condensed pentacyclic skeleton fits into the minor groove of DNA and preferentially recognizes AT-rich sequences. The monosubstituted compound 16d was identified as a potent cytotoxic DNA intercalator, whereas the disubstituted analogue 15d represents a new structural motif for the development of DNA sequence-reading small molecules.

Abstract
Bifunctional DNA intercalating agents have long attracted considerable attention as anticancer agents. One of the lead compounds in this category is the dimeric antitumor drug elinafide, composed of two tricyclic naphthalimide chromophores separated by an aminoalkyl linker chain optimally designed to permit bisintercalation of the drug into DNA. In an effort to optimize the DNA recognition capacity, different series of elinafide analogues have been prepared by extending the surface of the planar drug chromophore which is important for DNA sequence recognition. We report here a detailed investigation of the DNA sequence preference of three tetracyclic monomeric or dimeric pyrazinonaphthalimide derivatives. Melting temperature measurements and surface plasmon resonance (SPR) studies indicate that the dimerization of the tetracyclic planar chromophore considerably augments the affinity of the drug for DNA, polynucleotides, or hairpin oligonucleotides and promotes selective interaction with G.C sites. The (CH(2))(2)NH(CH(2))(3)NH(CH(2))(2) connector stabilizes the drug-DNA complexes. The methylation of the two nitrogen atoms of this linker chain reduces the binding affinity and increases the dissociation rates of the drug-DNA complexes by a factor of 10. DNase I footprinting experiments were used to investigate the sequence selectivity of the drugs, demonstrating highly preferential binding to G.C-rich sequences. It also served to select a high-affinity site encompassing the sequence 5'-GACGGCCAG which was then introduced into a biotin-labeled hairpin oligonucleotide to accurately measure the binding parameters by SPR. The affinity constant of the unmethylated dimer for this sequence is 500 times higher than that of the monomer compound and approximately 10 times higher than that of the methylated dimer. The DNA groove accessibility was also probed with three related oligonucleotides carrying G --> c(7)G, G --> I, and C --> M substitutions. The level of drug binding to the two hairpin oligonucleotides containing 7-deazaguanine (c(7)G) or 5-methylcytosine (M) residues is unchanged or only slightly reduced compared to that of the unmodified target. In contrast, incorporation of inosine (I) residues considerably decreases the extent of drug binding or even abolishes the interaction as is the case with the monomer. The pyrazinonaphthalimide derivatives are thus much more sensitive to the deletion of the exocyclic guanine 2-amino group exposed in the minor groove of the duplex than to the modification of the major groove elements. The complementary SPR footprinting methodology combining site selection and quantitative DNA affinity analysis constitutes a reliable method for dissecting the DNA sequence selectivity profile of reversible DNA binding small molecules.

Abstract
Bisnaphthalimides represent a promising group of DNA-targeted anticancer agents. In this series, the lead compounds elinafide and bisnafide have reached clinical trials, and the search for more potent analogues remains a priority. In the course of a medicinal chemistry program aimed at discovering novel antitumor drugs based on the naphthalimide skeleton, different dimeric molecules containing two tetracyclic neutral DNA intercalating chromophores were synthesized. The naphthalimide unit has been fused to a benzene ring (azonafide derivatives), an imidazole, a pyrazine, or, as reported here, a furan ring which increases the planar surface of the chromophore and enhances its stacking properties. We report a detailed investigation of the DNA binding capacity of the dimeric molecule MCI3335 composed of two furonaphthalimide units connected by a 12 A long amino alkyl linker [(CH(2))(2)-NH-(CH(2))(3)-NH-(CH(2))(2)] identical to that of elinafide. Qualitative and quantitative binding studies, in particular using surface plasmon resonance, establish that the dimer binds considerably more tightly to DNA (up to 1000 times) than the corresponding monomer and exhibits a higher sequence selectivity for GC-rich sequences. DNase I footprinting experiments attest that the dimer, and to a lesser extent the monomer, preferentially intercalate at GC sites. The strong binding interaction between the drugs and DNA perturbs the relaxation of supercoiled DNA by topoisomerases, but the test compounds do not promote DNA cleavage by topoisomerase I or II. Despite the lack of poisoning effect toward topoisomerase II, MCI3335 displays a very high cytotoxicity toward CEM human leukemia cells, with an IC(50) in the low nanomolar range, approximately 4 times inferior to that of the reference drug elinafide. Confocal microscopy observations indicate that the monomer shows a stronger tendency to accumulate in the cell nuclei than the dimer. The extremely high cytotoxic potential of MCI3335 is attributed to its enhanced capacity to bind to DNA and to inhibit DNA synthesis, as evidenced by flow cytometry experiments using the BrdU assay. The results provide novel mechanistic information that furthers the understanding of the structure-activity relationships in the bisnaphthalimide series and identify MCI3335 as a novel lead compound for further preclinical investigations.

Abstract
Several benzo[c]pyrido[2,3,4-kl]acridines bearing different substituents on the A and E rings were synthesized and evaluated for their capacity to bind to DNA and to inhibit DNA topoisomerases. Potent cytotoxic compounds were discovered but no strict correlation with their DNA binding affinity and effects on topoisomerases were observed. DNA is one but not the unique target of these compounds.

Abstract
New oxa-spermine homologues 5-9 were synthesised and their anticancer properties were evaluated against a broad spectrum of cancer cells. All compounds, except 9 showed average GI(50) values in the range of 1.89-7.56 microM. SAR studies showed that the cytotoxic activity of these novel oxa-spermines depended on the length of the alkyl chain, the position of the oxa-amino functionality and also, on the type of sulphonamido group in the molecule. Although the mechanism of action of these compound remains to be elucidated, it would appear that direct drug-DNA interactions are not involved in the mode of action of these drugs.
