Abstract
Cancer is a major health issue adsorbing the attention of a biomedical research. To fight this disease, new drugs are developed, specifically tailored to target biological pathways or peculiar components of the tumour cells. Particularly interesting is the use of intercalating agents as drugs capable to bind DNA and inhibit enzymes involved in DNA metabolism. Anthracyclines are the most commonly used anticancer drugs. In particular, daunomycin is used to cancer treatment by exploiting its ability to intercalate DNA and inhibit the activity of DNA topoisomerases implicated in the replication processes. Unfortunately, clinical application of anthracyclines is limited by their side effects. The conjugation with specific carriers could affect the selectivity and reduce side effect by improving stability and/or cellular uptake properties. We here report the biochemical characterisation of a daunomycin oligopeptide conjugate containing six residues of arginine, by the analysis of its fluorescence properties, DNA interaction and topoisomerases inhibitory effects.

Abstract
BACKGROUND Interaction of the plant alkaloid aristololactam-β-d-glucoside and the antitumor drug daunomycin with single stranded RNAs poly(G), poly(I), poly(C) and poly(U) has been investigated. METHODS Biophysical techniques of absorption, fluorescence, competition dialysis, circular dichroism, and microcalorimetry have been used. RESULTS Absorption and fluorescence studies have revealed noncooperative binding of ADG and DAN to the single stranded RNAs. The binding affinity of ADG varied as poly(G) > poly(I) > > poly(C) > poly(U). The affinity of DAN was one order higher than that of ADG and varied as poly(G) > poly(I) > poly(U) > poly(C). This binding preference was further confirmed by competition dialysis assay. The thermodynamics of the binding was characterised to be favourable entropy and enthalpic terms but their contributions were different for different systems. The major non-polyelectrolytic contribution to the binding revealed from salt dependent data appears to be arising mostly from stacking of DAN and ADG molecules with the bases leading to partial intercalation to single stranded RNA structures. Small negative heat capacity values have been observed in all the four cases. CONCLUSIONS This study presents the comparative structural and thermodynamic profiles of the binding of aristololactam-β-d-glucoside and daunomycin to single stranded polyribonucleotides. GENERAL SIGNIFICANCE These results suggest strong, specific but differential binding of these drug molecules to the single stranded RNAs and highlight the role of their structural differences in the interaction profile.

Abstract
The plant alkaloid aristololactam-β-d-glucoside and the anticancer chemotherapy drug daunomycin are two sugar bearing DNA binding antibiotics. The binding of these molecules to three double stranded ribonucleic acids, poly(A)·poly(U), poly(I)·poly(C) and poly(C)·poly(G), was studied using various biophysical techniques. Absorbance and fluorescence studies revealed that these molecules bound non-cooperatively to these ds RNAs with the binding affinities of the order 10(6) for daunomycin and 10(5) M(-1) for aristololactam-β-d-glucoside. Fluorescence quenching and viscosity studies gave evidence for intercalative binding. The binding enhanced the melting temperature of poly(A)·poly(U) and poly(I)·poly(C) and the binding affinity values evaluated from the melting data were in agreement with that obtained from other techniques. Circular dichroism results suggested minor conformational perturbations of the RNA structures. The binding was characterized by negative enthalpy and positive entropy changes and the affinity constants derived from calorimetry were in agreement with that obtained from spectroscopic data. Daunomycin bound all the three RNAs stronger than aristololactam-β-d-glucoside and the binding affinity varied as poly(A)·poly(U) > poly(I)·poly(C) > poly(C)·poly(G). The temperature dependence of the enthalpy changes yielded negative values of heat capacity changes for the complexation suggesting substantial hydrophobic contribution to the binding process. Furthermore, an enthalpy-entropy compensation behavior was also seen in all systems. These results provide new insights into binding of these small molecule drugs to double stranded RNA sequences.

Abstract
Differential scanning calorimetry and UV thermal denaturation have been used to determine a complete thermodynamic profile for the bis-intercalative interaction of the peptide antibiotic echinomycin with DNA. The new calorimetric data are consistent with all previously published binding data, and afford the most rigorous and direct determination of the binding enthalpy possible. For the association of echinomycin with DNA, we found DeltaG degrees = -7.6 kcal mol(-1), DeltaH = +3.8 kcal mol(-1) and DeltaS = +38.9 cal mol(-1) K(-1) at 20 degrees C. The binding reaction is clearly entropically driven, a hallmark of a process that is predominantly stabilized by hydrophobic interactions, though a deeper analysis of the free energy contributions suggests that direct molecular recognition between echinomycin and DNA, mediated by hydrogen bonding and van der Waals contacts, also plays an important role in stabilizing the complex.

Abstract
Actinomycin-D (actD) binds to natural DNA at two different classes of binding sites, weak and strong. The affinity for these sites is highly dependent on DNA sequence and solution conditions, and the interaction appears to be purely entropic driven. Although the entropic character of this reaction has been attributed to the release of water molecules upon drug to DNA complex formation, the mechanism by which hydration regulates actD binding and discrimination between different classes of binding sites on natural DNA is still unknown. In this work, we investigate the role of hydration on this reaction using the osmotic stress method. We show that the decrease of solution water activity, due to the addition of sucrose, glycerol, ethylene glycol, and betaine, favors drug binding to the strong binding sites on DNA by increasing both the apparent binding affinity delta G, and the number of DNA base pairs apparently occupied by the bound drug nbp/actD. These binding parameters vary linearly with the logarithm of the molar fraction of water in solution log(chi w), which indicates the contribution of water binding to the energetic of the reaction. It is demonstrated that the hydration change measured upon binding increases proportionally to the apparent size of the binding site nbp/actD. This indicates that nbp/actD, measured from the Scatchard plot, is a measure of the size of the DNA molecule changing conformation due to ligand binding. We also find that the contribution of DNA deformation, gauged by nbp/actD, to the total free energy of binding delta G, is given by delta G = delta Glocal + nbp/actD x delta GDNA, where delta Glocal = -8020 +/- 51 cal/mol of actD bound and delta GDNA = -24.1 +/- 1.7 cal/mol of base pair at 25 degrees C. We interpret delta Glocal as the energetic contribution due to the direct interactions of actD with the actual tetranucleotide binding site, and nbp/actD x delta GDNA as that due to the change in conformation, induced by binding, of nbp/actD DNA base pairs flanking the local site. This interpretation is supported by the agreement found between the value of delta GDNA and the torsional free energy change measured independently. We conclude suggesting an allosteric model for ligand binding to DNA, such that the increase in binding affinity is achieved by increasing the relaxation of the unfavorable free energy of binding storage at the local site through a larger number of DNA base pairs. The new aspect on this model is that the "size" of the complex is not fixed but determined by solutions conditions, such as water activity, which modulate the energetic barrier to change helix conformation. These results may suggest that long-range allosteric transitions of duplex DNA are involved in the inhibition of RNA synthesis by actD, and more generally, in the regulation of transcription.

Abstract
Ethidium was found to be efficiently cross-linked to DNA by glyoxal. Kinetic studies showed that the rate of the cross-linking reaction is strongly dependent on the glyoxal concentration. Comparative studies using a series of phenanthridines and acridines showed that NH2 groups at both the 2 and 7 positions on the phenanthridine ring are necessary for efficient cross-linking. Studies using synthetic polydeoxynucleotides showed that the 2-amino group of guanine is absolutely required for cross-linking. Fluorescence contact energy transfer and relative viscosity experiments showed that the cross-linked drug remains intercalated into DNA. DNA gel electrophoresis and melting studies demonstrated that cross-linked ethidium does not dissociate the DNA double helix to single strands.

Abstract
The equilibrium interaction of doxorubicin and its N-acetyl derivative with a series of purine-pyrimidine alternating polydeoxynucleotides has been studied through spectrofluorometry to assess the relevance of the electrostatic contribution to DNA intercalation. The results have shown that: (a) the suppression of the positive charge on the aminosugar has: (I) a profound negative effect on the free energy of intercalation, as expected, and (II) a negligible influence on the base specificity, which supports the notion of an essentially electrostatic effect of N-acetylation on intercalation; (b) a reasonably good accord with the demands of a polyelectrolytic model, due to Friedman and Manning, is found.

Abstract
The rate of constant for hydrolysis of a series of 4-substituted aniline mustards Ar-X-pC6H4-N(CH2CH2Cl)2, where Ar is 4-anilinoquinolinium and X = O, CH2, CONH and CO, have been measured in water and 0.02 M imidazole buffer at 37 degrees C and in 50% aqueous acetone at 66 degrees C. The equilibrium binding constants of the compounds and their hydrolysis products to nucleic acids of differing base composition have been determined at varying ionic strengths, and the results are consistent with the compounds binding as expected in the DNA minor groove. The alkylating reactivity of the mustards towards these nucleic acids has been measured in water at 37 degrees C and in 0.01 M HEPES buffer over a range of temperatures from 25 degrees C to 60 degrees C. Evaluation of the thermodynamic parameters for these kinetic and equilibrium studies suggests that the interaction with nucleic acids is via an internal SN2 mechanism involving an aziridinium ion.

Abstract
Thermal denaturation of natural DNA in the absence and presence of antitumor anthracycline antibiotics has been studied by adiabatic differential scanning calorimetry. The helix-coil transition is operationally irreversible as measured by DSC. Both the melting temperature and the overall molar transition enthalpy of the DNA samples was dependent on the percentage of GC base pairs. Calorimetric traces of anthracycline-DNA complexes have qualitatively similar features and the significance of this characteristic is discussed. The unsaturated drug-DNA complex melts through complex thermal transitions with one broad endotherm in the same temperature region as free DNA and the other at a higher temperature which is rf (mol ligand per mol DNA in base pairs) value dependent. Antibiotic binding at concentrations close to saturating conditions (rf = 0.2) reverts the melting range to a value near to its original one and increases the thermal stability of the duplex structure by around 30 degrees C. In addition, the calorimetric enthalpy is increased by between 64% and 150%, depending on which ligand was used.

Abstract
We have employed a combination of temperature-dependent UV absorption spectroscopy, circular dichroism, and batch calorimetry to characterize the binding of actinomycin D to a series of oligomeric DNA duplexes. We find the duplex [d(CGTCGACG)]2 to be unique in its ability to bind actinomycin D strongly despite the absence of a classic GpC site. We present evidence that this non-GpC-containing duplex binds two actinomycin D molecules in an apparently cooperative manner to form a complex that exhibits aberrant spectroscopic and calorimetric behavior. We propose that these observations are consistent with actinomycin D exhibiting a high-affinity, sequence-dependent DNA-binding mode distinct from its classic binding to isolated GpC sites.

Abstract
The binding of a few drugs (ethidium bromide, propidium diiodide, proflavine and actinomycin D) to DNA has been investigated in aqueous solutions to which cosolvents of different polarity have been added. It is found that both alcohols (less polar than water) and amides (more polar) lower the binding constant according to a linear relationship between the intercalation free energy and cosolvent concentration. The main action of cosolvents cannot be described in terms of electrostatic effects, since they predict much smaller changes in the binding constant than those observed. It appears instead that relevant solvation effects are responsible for the binding strength of the different dyes to DNA. As a general result, it is found that solvation effects largely contribute to the intercalation free energy, thereby weakening the influence of nonspecific interactions at the intercalation site.

Abstract
Batch calorimetry, differential scanning calorimetry (DSC), uv/vis absorption spectroscopy, fluorescence spectroscopy, and circular dichroism (CD), have been used to detect, monitor, and thermodynamically characterize the binding of daunomycin, dipyrandenium, dipyrandium, and netropsin to poly d(AT) and actinomycin D to salmon testes (ST) DNA. The following thermodynamic binding profiles have been obtained. (table; see text) All the poly d(AT) binding studies were done at 25 degrees C while actinomycin binding to ST DNA was performed at 1 degree C to enhance drug solubility. These thermodynamic parameters are interpreted in terms of specific interactions that have been proposed as part of models for the binding of each drug.

Abstract
Results are reported on equilibrium and kinetic experiments probing the DNA binding properties of a series of actinomycin analogues differing at the 3'-amino acid position. While the parent compound, actinomycin D, contains proline at this position on both pentapeptide lactone rings, the analogues under consideration here contain either azetidine-2-carboxylic acid, pipecolic acid, or 4-ketoproline on one or both pentapeptide rings. This study extends our earlier results on doubly substituted analogues [Shafer, R.H., Burnett, R. R., & Mirau, P.A. (1980) Nucleic Acids Res. 8, 1121]. DNA binding constants were determined from Scatchard plots constructed from visible absorption data and covered the range of (0.3-9) X 10(6) M-1 for the whole series of analogues. The thermal denaturation temperature of calf-thymus DNA was increased by 3-17 degrees C. DNA dissociation kinetics, along with enthalpies and entropies of activation, were also determined. The time constant for the slowest dissociation process ranged from 278 to 10 900 s. The strongest DNA binding analogue, in terms of the largest binding constant, the largest increase in DNA thermal denaturation temperature, and the slowest DNA dissociation rate, was actinomycin V, which has 4-ketoproline in the beta peptide ring, while the weakest DNA binding analogue has pipecolic acid on both peptide rings. Evidence is presented for one peptide ring exerting a greater influence than the other in the interaction with DNA. Also, the possible role of cis-trans isomerization about one or two peptide bonds in determining the slow DNA binding kinetics is discussed.

Abstract
Experiments are described that measure DNA dissociation kinetics and thermal denaturation temperatures for a series of actinomycin analogs containing, in the 3' amino acid position, pipecolic acid, proline or azetidine-2-carboxylic acid. Also included are studies on actinomycin C3. Analysis of the temperature dependence of the slowest rate constant for DNA dissociation shows that both the enthalpy and entropy of ativation increase as the ring size of the 3' amino acid decreases from six to five to four. All compounds increase the DNA melting temperature to the same extent except for the analog containing pipecolic acid, which shows a smaller effect. These results are discussed in terms of a possible role for conformational changes in the actinomycin pentapeptide lactone rings in determining the slow DNA dissociations rates for this class of intercalators. It is suggested that cis-trans isomerization of proline may be important in this regard.

Abstract
The results of thermal denaturation, fluorescence, calorimetric and viscosimetric studies on the interaction of adriamycin and its beta anomer with DNA are reported. Whereas all equilibrium, hydrodynamic and thermodynamic measurements are consistent with the proposed intercalative binding model for the adriamycin-DNA complex, the binding mechanism for the reaction of the beta anomer with DNA remains uncertaian. All DNA binding properties of this stereoisomer are substantially different from those of the parent compound. The results suggest that the amino sugar residue of the natural antibiotic may interact stero-specifically with the DNA helix, thus dictating the orientation of the tetracvclic chromophore within the intercalation site. The alteration in the DNA binding capacity and the changes in interactions with DNA following in inversion of configuration at C-1', parallel a lack of biological activity observed for the beta anomer.

Abstract
The association constant for the interaction of daunomycin with DNA was determined as a function of temperature (using [3H] daunomycin in conventional equilibrium dialysis cells) and ionic strength (using a spectrophotometric titration method). The association constant varied between 3.1 X 10(-6) M(-1) (4 degrees C) and 3.9 X 10(5) M(-1) (65 degrees C). The free energy change was -8.2 to -8.8 kcal/mol, the enthalpy change -5.3 kcal/mol and the entropy change +10 to +11 eu, all values being consistent with that expected of an intercalation process. The apparent number of intercalation sites detected (0.15 to 0.16 per nucleotide) was independent of temperature. The large positive entropy change accompanying the interaction appears to be due to extensive release of water from the DNA and daunomycin. The apparent number of binding sites increased dramatically with decrease of ionic strength, although the apparent association constant remained largely unaffected by ionic strength.

Abstract
In order to show that naturally occurring actinomycin D can be used as a fluorescent cytochemical probe, the fluorescence spectra of 50 micronM solution of actinomycin D in several solvents and in its DNA complex are reported. The excitation spectra of both bands observed are compared to the absorption spectrum, and the fluorescence quantum yields is estimated to be 0.65-10(-4), taking rhodamine B as a reference. Strong solvent-induced spectrum modifications are evidenced, interpreted as a solvent shell reorientation about the molecule chromophore in the excited state. The changes in the fluorescence spectrum of actinomycin due to an interaction with DNA (marked blue shift and decreased quantum yield) cannot be interpreted as a solvent effect; they express the properties of the DNA-chromophore eta-complex involving an orbital overlapping of actinomycin and guanine in DNA.

Abstract
Echinomycin is a peptide antibiotic which binds strongly to double-helical DNA up to a limit of approximately one molecule per five base-pairs. There is no detectable interaction with rRNA and only extremely feeble non-specific interaction with poly(rA)-poly(rU). Heat denaturation of DNA greatly decreases the binding, and similarly limited interaction is observed with naturally occurring single-stranded DNA. Association constants for binding to nine double-helical DNA species from different sources are presented; they vary by a factor of approximately 10, but are not simply related to the gross base composition. The interaction with DNA is ionic-strength-dependent, the binding constant falling by a factor of 4 when the ionic strength is raised from 0.01 to 0.10mol/litre. From the effect of temperature on the association constant for calf thymus DNA, the enthalpy of interaction is calculated to be about -13kJ/mol (-3kcal/mol). Binding of echinomycin persists in CsCl gradients and the buoyant density of nicked bacteriophage PM2 DNA is decreased by 25 mg/ml. Echinomycin interacts strongly with certain synthetic poly-deoxynucleotides, the binding constant decreasing in the order poly(dG)-poly(dC) greater than poly(dG-dC) greater than poly(dA-dT). For the latter two polymers the number of base-pairs occluded per bound antibiotic molecule is calculated to be three, whereas for poly(dG)-poly(dC) it is estimated to be four to five. Poly(dA)-poly(dT) and poly(dI)-poly(dC) interact only very weakly with the antibiotic. Poly(dI-dC) interacts to a slightly greater extent, but the binding curve is quite unlike that seen with the three strongly binding synthetic polynucleotides. Echinomycin affects the supercoiling of closed circular duplex bacteriophage PM2 DNA in the characteristic fashion of intercalating drugs. At low ionic strength the unwinding angle is almost twice that of ethidium. Likewise the extension of the helix, determined from changes in the viscosity of rod-like sonicated DNA fragments, is nearly double that expected for a simple (monofunctional) intercalation process. On this basis the interaction process is characterized as bifunctional intercalation. At higher ionic strength the unwinding angle relative to that of ethidium and the helix extension per bound echinomycin molecule fall, indicating a smooth progression towards more nearly monofunctional intercalation. Two simpler compounds which act as analogues of the quinoxaline chromophores of echinomycin, quinoxaline-2-carboxamide and the trypanocidal drug Bayer 7602, interact with DNA very much more weakly than does echinomycin, showing that the peptide portion of the antibiotic plays an essential role in determining the strength and specificity of the interaction.

Abstract
Daunomycin, adriamycin and 5 semisynthetic anthracycline antibiotics inhibited oxygen consumption or ATP production of rat heart mitochondria in vitro. The no-effect levels varied depending on the substrate used and ranged from 1 nmole per mg mitochondrial protein. Mitochondrial functions were also studied in hearts of rats treated with repeated i.p. injections of the 7 antibiotics. Decrease in oxygen consumption without change in ATP production was observed with adriamycin and NSC-149584. Daunomycin, NSC-164011, NSC-143496 NSC-143114 affected primarily ATP production. The most potent compounds were daunomycin and adriamycin which damaged mitochondrial function at cummulative doses of approximately 10 mg/kg. ECGs were monitored in groups of equally treated rats. Cardiotoxicity manifested itself by progressive widening of the QRS complex often followed by the development of a S-wave trough. The most toxic compounds also induced intraventricular block, bradycardia and heart failure. The development of the ECG changes showed a good correlation with the impairment of mitochondrial function.

Abstract
The interaction of two natural tetra-azacyclopentazulene dyes with native calf thymus DNA was studied by means of microcalorimetric, viscosimetric, and spectroscopic measurements. The results are consistent with the hypothesis of an intercalative-binding. However, comparison of calorimetric studies shows that the changes in enthalpy associated with the interaction of these compounds with DNA are, in absolute value, significantly lower than those found with known intercalating agnets (daunomycin, ethidium bromide). The influence of these dyes on the template capacity of DNA in the in vitro synthesis of nucleic acids was also determined. Under the conditions used, these compounds selectively inhibited DNA synthesis. No appreciable inhibitory effect upon E. coli RNA polymerase was observed. Both compounds had greater inhibitory effect on rat liver high molecular weight DNA polymerase than E. coli DNA polymerase I. Zoanthoxanthin was a more effective inhibitor than 3-norzoanthoxanthin.

Abstract
Daunomycin and adriamycin, are more mutagenic and antibacterial for a strain of Salmonella typhimurium defective for the uvrB gene than for its uvr+ counterpart. Other intercalating agents, as some acridine dyes, affect equally the two bacterial strains.
