Abstract
Paclitaxel (PTX) and docetaxel (DTX) are key members of taxanes with high anti-tumor activity against various cancer cells. These chemotherapeutic agents suffer from a number of drawbacks and it seems that low solubility in water is the most important one. Although much effort has been made in improving the bioavailability of PTX and DTX, the low bioavailability and minimal accumulation at tumor sites are still the challenges faced in PTX and DTX therapy. As a consequence, bio-based nanoparticles (NPs) have attracted much attention due to unique properties. Among them, chitosan (CS) is of interest due to its great biocompatibility. CS is a positively charged polysaccharide with the capability of interaction with negatively charged biomolecules. Besides, it can be processed into the sheet, micro/nano-particles, scaffold, and is dissolvable in mildly acidic pH similar to the pH of the tumor microenvironment. Keeping in mind the different applications of CS in the preparation of nanocarriers for delivery of PTX and DTX, in the present review, we demonstrate that how CS functionalized-nanocarriers and CS modification can be beneficial in enhancing the bioavailability of PTX and DTX, targeted delivery at tumor site, image-guided delivery and co-delivery with other anti-tumor drugs or genes.

Abstract
Surface engineering of nanoparticles plays an essential role in their colloidal stability, biocompatibility and interaction with biosystems. In this study, a novel multidentate zwitterionic biopolymer derivative is obtained from conjugating dithiolane lipoic acid and zwitterionic acryloyloxyethyl phosphorylcholine to the chitosan oligosaccharide backbone. Gold nanoparticles (AuNPs) modified by this polymer exhibit remarkable colloidal stabilities under extreme conditions including high salt conditions, wide pH range and serum or plasma containing media. The AuNPs also show strong resistance to competition from dithiothreitol (as high as 1.5 M). Moreover, the modified AuNPs demonstrate low cytotoxicity investigated by both MTT and LDH assays, and good hemocompatibility evaluated by hemolysis of human red blood cells. In addition, the intracellular fate of AuNPs was investigated by ICP-MS and TEM. It showed that the AuNPs are uptaken by cells in a concentration dependent manner, and they can escape from endosomes/lysosomes to cytosol and tend to accumulate around the nucleus after 24 h incubation but few of them are excreted out of the cells. Gold nanorods are also stabilized by this ligand, which demonstrates robust dispersion stability and excellent hemocompatibility. This kind of multidentate zwitterionic chitosan derivative could be widely used for stabilizing other inorganic nanoparticles, which will greatly improve their performance in a variety of bio-related applications.

Abstract
Aim: The objective of this study was to investigate the influence of the high-pressure homogenization (HPH) process and stabilizers on the physicochemical properties of glycerol monooleate (GMO)/chitosan nanostructures using curcumin as a model hydrophobic drug. Materials & methods: The oil-in-water nanoemulsion of the GMO/chitosan system was prepared by sonication and HPH techniques using two different stabilizers (polyvinyl alcohol [PVA] and poloxamer 407). The particle size (PS), ζ-potential (ZP) and physical stability of the nanoemulsion were investigated. These nanoemulsions were lyophilized and characterized for PS, ZP, surface morphology, moisture content and physical form of the drug in the nanostructures. The in vitro release and the uptake of curcumin in Caco-2 cells were evaluated using an ultra-performance liquid chromatography method. Results: Three cycles of HPH produced a 50–65% reduction in the PS of the nanoemulsion. A change in stabilizer, from PVA to poloxamer, did not affect the PS, physical stability, moisture content or the physical form of the drug in the formulation. However, there was a significant change in the ZP, surface morphology, in vitro release rate and cellular uptake from the two formulations. Conclusion: The process of HPH effectively reduces the PS of the GMO/chitosan nanoemulsions loaded with the hydrophobic drug. The type of stabilizer used affects several physicochemical properties of the GMO/chitosan nanostructures. Compared with PVA, poloxamer 407 is a more effective stabilizer for stabilizing the GMO/chitosan system containing a hydrophobic drug nanoemulsion at low concentrations.

Abstract
Aims: The present research focuses on the development of the surface modified solid lipid nanoparticulate (SLN) system for enhancing the stability and sustaining the release of a model hydrophilic drug ifosfamide. Materials & Methods: SLNs consisting of glyceryl monooleate (GMO) and chitosan were prepared by double emulsion technique, crosslinked with sodium tripolyphosphate, followed by lyophilization under two different vacuum conditions. The physicochemical characterization of SLNs included evaluation of surface morphology, particle size and surface charge, moisture content and physical state of the drug in the delivery system. The in vitro drug release and the stability were evaluated using high-performance liquid chromatography and liquid chromatography/mass spectrometry, respectively. Cellular permeability and subcellular localization studies were performed using Caco-2 cells. Results: Different chamber pressures during lyophilization produced SLNs with different morphologies and moisture contents. SLNs demonstrated high encapsulation efficiency, sustained release, and enhanced stability of ifosfamide with a high cellular uptake and permeability for Caco-2 cells. Conclusion: GMO and chitosan SLNs could be successfully used for enhancing the stability, sustaining the release, enhancing the targeting and permeability characteristics of ifosfamide.

Abstract
To date cancer is considered as one of the most devastating diseases due to its high rate of mortality. Preclinical studies have demonstrated that the Akt/mTOR (mammalian target of rapamycin) pathway is activated in cancers and inhibition of this pathway has great potential in anti-cancer therapy. Rapamycin, one of the most potent anti-cancer drugs, blocks Akt/mTOR function and has anti-proliferative activity in several cancers. To circumvent problems associated with rapamycin due to its poor water solubility, poor oral bioavailability, low accessibility to cancer tissues and systemic toxicity, rapamycin-loaded cubic nanoparticles (NP) were formulated with vitamin E d-α-tocopheryl polyethylene glycol 1000 succinate (TPGS) as an emulsifier for oral delivery. Cubic NP were characterised and these particles demonstrated better cytotoxicity and apoptosis compared with native rapamycin under in vitro conditions due to their enhanced cellular uptake. The molecular impact of particulate systems on the Akt/mTOR pathway were elucidated by immunoblotting. Down-regulation of different anti-apoptotic genes of this pathway indicates activation of apoptotic signals leading to MIA PaCa cell death. An in vivo study demonstrated enhanced bioavailability of rapamycin in cubic NP in comparison with native rapamycin in a mouse model with no toxicity and good biocompatibility of void cubic NP at a higher dose of oral administration. Thus, rapamycin-loaded cubic NP can be used as an effective drug delivery system to produce better rapamycin therapeutics for the treatment of cancers.

Abstract
Chemotherapeutic regimens incorporating taxanes significantly improve outcomes for patients with squamous cell carcinomas of the head and neck (SCCHN). However, treatment with taxanes is limited by toxicities, including bone marrow suppression and peripheral neuropathies. We proposed that conjugating taxanes to targeting carrier molecules would increase antitumor efficacy and decrease toxicity. The cell surface proteoglycan, CD44, is expressed on most SCCHNs, and we hypothesized that it is an attractive candidate for targeted therapy via its natural ligand, hyaluronic acid (HA). We determined whether HA-paclitaxel conjugates were able to decrease tumor growth and improve survival in orthotopic nude mouse human SCCHN xenograft models. HA-paclitaxel concentration-dependent growth inhibition of human SCCHN cell lines OSC-19 and HN5 in vitro, very similarly to free paclitaxel treatment. Tumor cell uptake of FITC-labeled HA-paclitaxel was significantly blocked with free HA, indicating the dependence of uptake on CD44. HA-paclitaxel administered intravenously once per week for three weeks at 120 mg/kg paclitaxel equivalents, far above the paclitaxel maximum tolerated dose, exerted superior tumor growth control to that of paclitaxel in both orthotopic OSC-19-luciferase and HN5 xenograft models in vivo. Mouse survival following HA-paclitaxel administration was prolonged compared with that of controls in mice implanted with either of these xenografts. Mice treated with HA-paclitaxel displayed increased TUNEL(+) cells in tumor tissue, as well as markedly reduced microvessel density compared to those treated with free paclitaxel. No acute histopathological changes were observed in mice treated with HA-paclitaxel. Thus, we conclude that HA-paclitaxel effectively inhibits tumor growth in human SCCHN xenografts via an HA-mediated mechanism and this conjugate should be considered for further preclinical development for this disease.

Abstract
AIMS This investigation compared the tumor distribution, efficacy, blood pharmacokinetic parameters and hematological alterations following treatment with chitosan/glyceryl-monooleate (GMO) nanostructures containing paclitaxel (PTX) to a conventional formulation of PTX (Taxol(®)) in BALB/c female mice. MATERIALS & METHODS The tumor and blood concentrations of PTX were evaluated by HPLC and the pharmacokinetic parameters were determined through noncompartmental methods. Tumor development was evaluated by histopathological methods and hematological composition was monitored through differential white blood cells counts. RESULTS Lower localized or intravenous doses of PTX-chitosan/GMO nanostructures significantly increased the antitumor activity of paclitaxel. The tumor distribution studies showed effective concentrations in the tumors with the chitosan/GMO formulation while systemic blood levels remained lower than after administration of the conventional formulation. CONCLUSION Delivery systems consisting of chitosan/GMO and PTX are safe and effective administered locally (intratumorally) or intravenously.

Abstract
Aim: The objective of the present study is to prepare and characterize nutlin-3a loaded polymeric poly(lactide-co-glycolide) nanoparticles (NPs) surface functionalized with transferrin ligand, to deliver the encapsulated drug in a targeted manner to its site of action and to evaluate the efficacy of the nanoformulation in terms of its cellular uptake, cell cytotoxicity, cell cycle arrest, apoptosis and activation of p53 pathway at molecular level in MCF-7 breast cancer cell line. Method: Nutlin-3a loaded poly(lactide-co-glycolide) NPs were prepared following the single oil-in-water emulsion method. Physicochemical characterization of the formulation included size and surface charge measurement, transmission electron microscopy characterization, study of surface morphology using scanning electron microscopy, Fourier-transform infrared spectral analysis and in vitro release kinetics studies. Furthermore, targeting ability of the conjugated system was assessed by cellular uptake and cell cytotoxicity studies in an in vitro cell model. Molecular basis of nutlin-3a-mediated p53 activation pathway was investigated by western blot analysis. Inhibition of cell cycle progression and apoptosis was evaluated by flow cytometry. Results: Physiochemical characterization of the formulations revealed that nutlin-3a was efficiently encapsulated in the nanoparticulate system, reaching an encapsulation efficiency of approximately 80% with size of approximately 220 nm and negative zeta potential of approximately -10.4 mV. Higher cellular uptake efficiency of the conjugated system proved the effectiveness of targeted therapy. IC50 values, as determined by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium assay, showed superior antiproliferative activity of transferrin-conjugated NPs over unconjugated NPs and native nutlin-3a, owing to enhanced cellular uptake by cancer cells. At the molecular level the conjugated system showed enhanced activation of p53 pathway in comparison to native drug as evident from western blot analysis. Augmented cell cycle arrest and apoptosis was exhibited by the conjugated system. Thus, our results suggest that transferrin-conjugated nutlin-3a loaded NPs could be a potential drug carrier system for targeted delivery of potent anticancer drug nutlin-3a for breast cancer therapy.

Abstract
Curcumin, the natural anticancer drug and its optimum potential is limited due to lack of solubility in aqueous solvent, degradation at alkaline pH and poor tissue absorption. In order to enhance its potency and improve bioavailability, we have synthesized curcumin loaded nanoparticulate delivery system. Unlike free curcumin, it is readily dispersed in aqueous medium, showing narrow size distribution 192 nm ranges (as observed by microscope) with biocompatibility (confocal studies and TNF-alpha assay). Furthermore, it displayed enhanced stability in phosphate buffer saline by protecting encapsulated curcumin against hydrolysis and biotransformation. Most importantly, nanoparticulate curcumin was comparatively more effective than native curcumin against different cancer cell lines under in vitro condition with time due to enhanced cellular uptake resulting in reduction of cell viability by inducing apoptosis. Molecular basis of apoptosis studied by western blotting revealed blockade of nuclear factor kappa B (NFkappaB) and its regulated gene expression through inhibition of IkappaB kinase and Akt activation. In mice, nanoparticulate curcumin was more bioavailable and had a longer half-life than native curcumin as revealed from pharmacokinetics study. Thus, the results demonstrated nanoparticulate curcumin may be useful as a potential anticancer drug for treatment of various malignant tumors.

Abstract
The objectives of this study are to enhance cellular accumulation of gemcitabine with chitosan/glyceryl monooleate (GMO) nanostructures, and to provide significant increase in cell death of human pancreatic cancer cells in vitro. The delivery system was prepared by a multiple emulsion solvent evaporation method. The nanostructure topography, size, and surface charge were determined by atomic force microscopy (AFM), and a zetameter. The cellular accumulation, cellular internalization and cytotoxicity of the nanostructures were evaluated by HPLC, confocal microscopy, or MTT assay in Mia PaCa-2 and BxPC-3 cells. The average particle diameter for 2% and 4% (w/w) drug loaded delivery system were 382.3 +/- 28.6 nm, and 385.2 +/- 16.1 nm, respectively with a surface charge of +21.94 +/- 4.37 and +21.23 +/- 1.46 mV. The MTT cytotoxicity dose-response studies revealed the placebo at/or below 1 mg/ml has no effect on MIA PaCa-2 or BxPC-3 cells. The delivery system demonstrated a significant decrease in the IC50 (3 to 4 log unit shift) in cell survival for gemcitabine nanostructures at 72 and 96 h post-treatment when compared with a solution of gemcitabine alone. The nanostructure reported here can be resuspended in an aqueous medium that demonstrate increased effective treatment compared with gemcitabine treatment alone in an in vitro model of human pancreatic cancer. The drug delivery system demonstrates capability to entrap both hydrophilic and hydrophobic compounds to potentially provide an effective treatment option in human pancreatic cancer.
