Abstract
Primaquine phosphate is a drug of choice for the treatment of malarial relapse. However, poor drug concentration in the hepatocytes and dose-related toxicity pose severe limitations. We report a nanocarboplex of primaquine phosphate by a simple in situ process using dextran sulphate as a carbohydrate polymer and pullulan as an asialoglycoprotein receptor ligand. Our aim was to preferentially enhance accumulation of the nanocarboplex in the hepatocytes. The in situ pullulan-anchored primaquine nanocarboplex was prepared by simple addition of a solution of dextran sulphate and pullulan with stabilizer to a measured quantity of primaquine phosphate in a vial, followed by shaking to obtain the primaquine phosphate nanocarboplex ready for injection. The nanocarboplex was characterized and evaluated in vivo for pharmacokinetics and biodistribution in the rat model. Specific uptake by hepatocytes in the liver was also quantified. Increase in t ½ with significant uptake in the RES organ was observed. More importantly, anchoring pullulan favored high liver uptake and preferential accumulation in the hepatocytes with a hepatocytes/nonparenchymal cells ratio of 75:25. The in situ primaquine phosphate nanocarboplex anchored with pullulan provides both a significant technological advantage and the desired targeting to the hepatocytes.

Abstract
This study deals with the preparation and investigation of a nanoscale delivery system for the anticancer drug doxorubicin (DOX) using its complexation with polyanionic carbohydrate dextran sulfate (DS). Dynamic light scattering, SEM, and zeta potential determination were used to characterize nanocomplexes. DOX-DS complexation was studied in the presence of ethanol as a hydrogen-bond disrupting agent, NaCl as an electrostatic shielding agent, and chitosan as a positively charged polymer. Thermodynamics of DOX-DS interaction was studied using isothermal titration calorimetry (ITC). A dialysis method was applied to investigate the release profile of DOX from DOX-DS nanocomplexes. Spherical and smooth-surfaced DOX-DS nanocomplexes (250–500 nm) with negative zeta potential were formed at a DS/DOX (w/w) ratio of 0.4–0.6, with over 90% drug encapsulation efficiency. DOX when complexed with DS showed lower fluorescence emission and 480 nm absorbance plus a 15 nm bathometric shift in its visible absorbance spectrum. Electrostatic hydrogen bonding and π-π stacking interactions are the main contributing interactions in DOX-DS complexation. Thermal analysis of DOX-DS complexation by ITC revealed that each DOX molecule binds with 3 DS glycosyl monomers. Drug release profile of nanocomplexes showed a fast DOX release followed by a slow sustained release, leading to release of 32% of entrapped DOX within 15 days. DOX-DS nanocomplexes may serve as a drug delivery system with efficient drug encapsulation and also may be taken into consideration in designing DOX controlled-release systems.

Abstract
We previously published evidence that oocytes exposed to doxorubicin (DXR), a widely used chemotherapeutic agent, rapidly undergo morphological and biochemical changes via discrete effector signaling pathways consistent with the occurrence of apoptosis. In this report, we elucidated the molecular requirements for actions of this drug in oocytes. Our results indicate that within 1 h of exposure DXR causes rapid DNA damage, and commits the oocyte to cytoplasmic fragmentation by the fourth hour, followed by delayed oocyte activation and execution of cytoplasmic fragmentation. Inhibitors that interfere with oocyte activation consistently rescue cytoplasmic fragmentation, but fail to suppress DNA damage. There was evidence of depletion of Bax, Caspase-2, MA-3 and Bcl-x transcripts, suggesting that modulations by DXR caused recruitment of these maternal transcripts into the translation process. Furthermore, sphingolipids such as sphingosine-1-phosphate and ceramide modulate DXR actions by, respectively, altering its intracellular trafficking, or by sustaining the drug's contact with DNA.

Abstract
Complexation of antitumor drug, doxorubicin (DOX), with poly(acrylic acid) (PAA) in buffer solutions was examined. The DOX-to-PAA binding was governed by electrostatic and stacking interactions resulting in a complex of characteristic composition with a PAA/DOX = 1.6 molar ratio. Sizes of the complex particles were found to lie in 600-900-nm range. However, the particles were able to interact with small neutral egg yolk lecithin liposomes (80-100 nm in diameter), a ternary DOX/PAA/liposome complex being formed. The observations and conclusions we made may be useful for interpreting biological effects of polymer-based bioactive constructs.

Abstract
A model, based on fluorescence data, is developed for the poly(acrylic acid)-assisted transport of doxorubicin, a cationic antitumor drug, through a bilayer membrane. Accordingly, the doxorubicin binds to the poly(acrylic acid) via electrostatic polymer-drug interactions plus drug-drug stacking within the complex. This complex associates with neutral egg lecithin vesicles by means of hydrophobic attraction between the doxorubicin and the vesicle bilayers. In the process, the doxorubicin "destacks", providing a fluorescence change that can be monitored. Finally, the doxorubicin enters the vesicle interior which has been imparted with an acidic pH to protonate the doxorubicin and thus, in a second stage, yield an additional fluorescence change that can also be detected. A portion of the poly(acrylic acid), now devoid of doxorubicin, then leaves the outer vesicle surface and enters to external solution.

Abstract
Despite the large number of publications describing the synthesis and physicocharacterization of the binding between drugs and DNA, relatively few examine drug delivery systems (DDSs) for these molecules. The aim to find DDSs for DNA-binding drugs (DBDs) was prompted mainly to reduce the toxicity and/or enhance the tumor specificity of systemically administered drugs. With this in mind, we have reviewed the biological effects of some DBDs that are currently used as antitumor drugs and describe a brief selection of DDSs currently in clinical trials or on the market.

Abstract
Naturally occurring 1,8-dihydroxyanthraquinones are under consideration as possible carcinogens. Here we wanted to elucidate a possible mechanism of their genotoxicity. All three tested anthraquinones, emodin, aloe-emodin, and danthron, showed capabilities to inhibit the non-covalent binding of bisbenzimide Hoechst 33342 to isolated DNA and in mouse lymphoma L5178Y cells comparable to the topoisomerase II inhibitor and intercalator m-amsacrine. In a cell-free decatenation assay, emodin exerted a stronger, danthron a similar and aloe-emodin a weaker inhibition of topoisomerase II activity than m-amsacrine. Analysis of the chromosomal extent of DNA damage induced by these anthraquinones was performed in mouse lymphoma L5178Y cells. Anthraquinone-induced mutant cell clones showed similar chromosomal lesions when compared to the topoisomerase II inhibitors etoposide and m-amsacrine, but were different from mutants induced by the DNA alkylator ethyl methanesulfonate. These data support the idea that inhibition of the catalytic activity of topoisomerase II contributes to anthraquinone-induced genotoxicity and mutagenicity.

Abstract
We had reported that the plant-derived 1,8-dihydroxyanthraquinone derivatives, emodin and danthron, were clearly genotoxic in mouse lymphoma L5178Y cells, whereas chrysophanol was only weakly genotoxic and physcion not at all. Danthron was more potent than emodin. Furthermore, we had found that these compounds bound non-covalently to DNA and inhibited topoisomerase II activity. Interestingly, in these systems emodin was more potent than danthron. This inversion of the ranking prompted us to investigate the underlying mechanism. Since emodin shows a high serum-protein binding affinity, horse serum used as a media-supplement in the mouse lymphoma genotoxicity assays was analyzed for a potential selective scavenging of emodin. Non-covalent DNA-binding in mouse lymphoma L5178Y cells was investigated in the absence or presence of serum. In the presence of 10% serum, the DNA-binding potency of emodin was markedly reduced and was lower than that of danthron. We also applied mutation assays with mouse lymphoma cells and AS52 cells and varied the serum concentration used. In the absence of serum emodin showed slightly higher mutagenicity in AS52 cells than danthron. At reduced serum concentration (0.5%) emodin was strongly cytotoxic to the mouse lymphoma cells. For chrysophanol and physcion, a considerable reduction of the non-covalent DNA-binding potency in intact cells was found when compared to danthron, in concordance with their lower genotoxic potency. Overall, these data support the understanding that the genotoxicity of anthraquinones is, at least in part, mediated by non-covalent DNA-binding.

Abstract
Polyalkylcyanoacrylate (PACA) nanoparticles loaded with doxorubicin allowed multidrug resistance to be overcome in vitro. However, increased cytotoxicity is not always correlated with an increased level of intracellular drug. Although we have previously shown that PACA nanoparticles are not endocytosed by tumour cells, we report here that a direct interaction between nanoparticles and cells is a necessary requirement for overcoming resistance. In addition, the results showed that the degradation products of PACA (mainly polycyanoacrylic acid) in the presence of doxorubicin are able to increase both accumulation and cytotoxicity, thus suggesting the formation of a doxorubicin-polycyanoacrylic acid ion pair. It is therefore concluded that resistance is overcome as a result of both the adsorption of nanoparticles to the cell surface and increased doxorubicin diffusion by the accumulation of an ion pair at the plasma membrane.
