Abstract
Our research aimed to enhance the oral bioavailability of doxorubicin hydrochloride (DOX·HCl) while minimizing the potential for myocardial toxicity. To achieve this goal, we developed a new method that utilizes a coating material to encapsulate the drug in liposomes, which can specifically target intestinal taurine transporter proteins. This coating material, TAU-CS, was created by combining taurine with chitosan. We characterized TAU-CS using various methods, including 1H NMR, FT-IR, and scanning electron microscopy (SEM). The resulting liposomes exhibited a regular spherical morphology, with a particle size of 195.7 nm, an encapsulation efficiency of 91.23 %, and a zeta potential of +11.65 mV. Under simulated gastrointestinal conditions, TAU-CS/LIP@DOX·HCl exhibited good stability and slow release. Pharmacokinetic studies revealed that, compared with DOX·HCl, TAU-CS/LIP@DOX·HCl had a relative bioavailability of 342 %. Intracellular uptake, immunofluorescence imaging, and permeation assays confirmed that the taurine transporter protein mediates the intestinal uptake of these liposomes. Our study suggested that liposomes coated with TAU-CS could serve as an effective oral delivery system and that targeting the taurine transporter protein shows promise in enhancing drug absorption.

Abstract
In this study, we synthesized a novel compound, agmatine-cholesterol conjugate (AG-Chol), to enhance the anti-tumor activity of drug-loaded liposomes. We replaced cholesterol with AG-Chol in preparing doxorubicin hydrochloride (DOX) liposomes by using an active loading method for DOX. We assessed the physical and chemical properties of the resulting AG-Liposomes and evaluated their efficacy in vitro and in vivo. The results showed that AG-Liposomes were stable with high encapsulation efficiency. Compared with the control liposomes, AG-Liposomes exhibited a slower drug release rate in the release medium at pH 6.8. The in vitro cell experiments demonstrated that AG-Liposomes had higher tumor cell uptake rate, stronger migration inhibition rate, higher apoptosis rate, better anti-clonogenic ability, and higher lysosome escape ability than the control liposomes. In vivo distribution results demonstrate that liposomes prepared with AG-Chol instead of cholesterol can significantly enhance their tumor targeting abilities and reduce their distribution to non-targeted sites. In vivo tumor suppression experiments showed that AG-Liposomes had a higher tumor suppression rate than the control liposomes without causing apparent toxicity to normal tissues, as evidenced by histological staining. Therefore, substituting cholesterol with AG-Chol in the preparation of liposomes can result in enhanced lysosome escape, improved tumor targeting, and increased efficacy of anti-tumor drugs.

Abstract
BACKGROUND Liposomal formulations have traditionally been considered the most therapeutically effective drug delivery systems (DDS). However, their pharmacokinetics study and efficacy assessment are still challenging given size heterogeneity and unknown forms in vivo. The pharmacodynamic evaluation that solely analyzes total drug concentration is unfit for the liposomal formulation study. Hence, it is crucial to develop effective strategies for the separation and analysis of different forms of liposomal formulations in order to contribute to the study of pharmacokinetic profiles associated with both liposome-incorporated and non-liposomal drugs. (84) RESULTS: A laboratory-built circular nonuniform electric field gel electrophoresis (CNEFGE) system was developed in this study for simultaneous separation and analysis of various forms of doxorubicin hydrochloride (DOX•HCl) liposomes. Liposomes were effectively fractionized based on their size and higher concentration in situ in the concentration zone, obtaining liposome recovery >95 % and a 3.04 concentration factor. It was found that the technique could be used to evaluate not only the size distribution of liposomes but also the drug loading capacity related to size. The charge-to-size-based separation mechanism has also allowed the simultaneous separation of liposome-entrapped drugs, protein-bound drugs, and free drugs in various forms, and the technique has been successfully employed in serum. Moreover, the quantification analysis of liposomes incubated with serum for 72 h showed that the proportion of the ratio of DOX•HCl in liposome-entrapped drugs, protein-bound drugs, and free drugs is approximately 97:2:1. (143) SIGNIFICANCE: Using the separation principle of gel electrophoresis and the electrification characteristics of drug carriers, this study developed and implemented an efficient approach for the simultaneous separation and concentration of multiple forms of drug liposomes in vivo. This approach offers a wide range of applications in the pharmacokinetics, efficacy, and safety evaluation of drug carriers and liposomes. (56).

Abstract
Hepatocellular carcinoma (HCC), more than 800 000 cases reported annually, is the most common primary liver cancer globally. Doxorubicin hydrochloride (Dox-HCl) is a widely used chemotherapy drug for HCC, but efficacy and tolerability are limited, thus critical to develop delivery systems that can target Dox-HCl to the tumour site. In this study, liver-targeting ligand glycyrrhetinic acid (Gly) was conjugated to polyethylene glycol (PEG) via Steglich reaction and incorporated in liposomes, which were then loaded with Dox-HCl by pH gradient method. The optimal formulation Gly-Peg-Dox-ProLP-F6 showed high Dox-HCl encapsulation capacity (90.0%±1.85%), low particle size (120 ± 3.2 nm). Gly-Peg-Dox-ProLP-F6 formulation demonstrated substantially greater toxicity against HCC cells than commercial Dox-HCl formulation (greater against 1.14, 1.5, 1.24 fold against Hep G2, Mahlavu and Huh-7 cells, respectively), but was 1.86-fold less cytotoxic against non-cancerous cell line AML-12. It increased permeability from apical to basolateral (A-B) approximately 2-fold. Gly-Peg-Dox-ProLP-F6 demonstrated superior antitumor efficacy in mouse liver cancer model as evaluated by IVIS. Isolated mouse liver tissue contained 2.48-fold Dox more than Dox-HCl after administration of Gly-Peg-Dox-ProLP-F6, while accumulation in heart tissue was substantially lower. This Gly-Peg-Dox-ProLP-F6 formulation may improve HCC outcomes through superior liver targeting for enhanced tumour toxicity with lower systemic toxicity.

Abstract
Herein, folic acid conjugated poly (NIPAM-co-functional palygorskite-Au-co-acrylic acid) (FA-PNFA) hybrid microgels were fabricated by emulsion polymerization. The introduction of acrylic acid can increase the low critical solution temperature (LCST) of FA-PNFA from 36 °C at pH 5.5-42 °C at pH 7.4. Doxorubicin hydrochloride (DOX) was chosen as the load drug, the results show that the DOX release behavior is driven by temperature, pH and light. Cumulative drug release rate can reach 74 % at 37 °C and pH 5.5 while only 20 % at 37 °C and pH 7.4, which effectively avoided the early leakage of the drug. In addition, by exposing FA-PNFA hybrid microgels to laser irradiation, the cumulative release rate was increased by 5 % compared to the release rate under dark conditions. Functional palygorskite-Au as physical crosslinkers not only improves the drug loading content of microgels but also promotes the release of DOX through light drive. Methyl thiazolyl tetrazolium bromide (MTT) assay demonstrated that the FA-PNFA are nontoxic up to 200 μg mL-1 towards 4T1 breast cancer cell. Meanwhile, DOX-loaded FA-PNFA show more significant cytotoxicity than the free DOX. Confocal laser scanning microscope (CLSM) revealed that the DOX-loaded FA-PNFA could be efficiently taken by 4T1 breast cancer cells. FA-PNFA hybrid microgels not only improve the LCST of PNIPAM, but also endow the microgels with photostimulation responsiveness, which can release drugs in response to the triple stimulation response of temperature, pH and light, thus effectively reducing the activity of cancer cells, making them more promising for wider medical applications.

Abstract
Hybrid nanoparticles made up of zein and various stabilizers were developed and characterized. In detail, a zein concentration of 2 mg/ml was blended with various amounts of different phospholipids or PEG-derivatives in order to obtain formulations with suitable physico-chemical properties for drug delivery purposes. Doxorubicin hydrochloride (DOX) was used as a model of a hydrophilic compound and its entrapment efficiency, release profile and cytotoxic activity were investigated. Photon correlation spectroscopy showed that the best formulations were obtained using DMPG, DOTAP and DSPE-mPEG2000 as stabilizers of zein nanoparticles, which were characterized by an average diameter of ~100 nm, a narrow size distribution and a significant time- and temperature-dependent stability. The interaction between protein and stabilizers was confirmed through FT-IR analysis, while TEM analysis showed the presence of a shell-like structure around the zein core. The release profiles of the drug from the zein/DSPE-mPEG2000 nanosystems, evaluated at two pHs (5.5 and 7.4), showed a prolonged and constant leakage of the drug. The encapsulation of DOX within zein/DSPE-mPEG2000 nanosystems did not compromise its biological efficacy, demonstrating the potential application of these hybrid nanoparticles as drug carriers.

Abstract
Osteosarcoma (OS) is the most common malignant tumor of the bone that affects children and adolescents, and its treatment usually involves doxorubicin hydrochloride (DOX). However, the drug resistance and side effects caused by high-dose DOX infusion greatly hinder its therapeutic effects. To achieve efficient OS treatment with low toxicity, an injectable rhein (RH)-assisted crosslinked hydrogel (PVA@RH@DOX hydrogel, PRDH) was designed, which was prepared by loading DOX and RH into a polyvinyl alcohol (PVA) solution. The cytotoxicity assay and live/dead staining results showed that the combination of RH and DOX more effectively killed OS cells, producing excellent effects at low concentrations of DOX. The wound healing and transwell test results proved that PRDH could significantly inhibit the metastasis and invasion of OS cells. PRDH showed a long-lasting antitumor effect after injection of a single dose, significantly suppressing the proliferation and metastasis of OS and achieving the strategy of a single administration for long-term treatment. Excitingly, RH facilitated hydrogel formation by assisting with PVA crosslinking. This system provides an alternative regimen and broadens the horizon for the clinical treatment of OS.

Abstract
In this study, octenyl succinic anhydride (OSA) starch with different folic acid (FA) grafting time was prepared and the degree of FA substitution at different grafting time was determined. The results of XPS quantitatively reflected the surface elemental composition of OSA starch grafted with FA. FTIR spectra further confirmed the successful introduction of FA on OSA starch granules. SEM images showed that the surface roughness of OSA starch granules was more obvious with higher FA grafting time. The particle size, zeta potential, and swelling properties were determined to study the effect of FA on the structure of OSA starch. TGA indicated that FA effectively enhanced the thermal stability of OSA starch at high temperature. The crystalline form of the OSA starch gradually transformed from A type to a hybrid A and V-type with the progress of FA grafting reaction. In addition, the anti-digestive properties of OSA starch were enhanced after grafting FA. Using doxorubicin hydrochloride (DOX) as the model drug, the loading efficiency of OSA starch grafted with FA for DOX reached 87.71 %. These results provide novel insights into OSA starch grafted with FA as potential strategy for loading DOX.

Abstract
In this study, Superparamagnetic magnetite nanoparticles (SPMNPs) are used in a new way as direct nanocarrier for Doxorubicin hydrochloride (DOX) via the functionalization of their surface with tri-sodium citrate through ligand exchange to conjugate DOX with imine bond to form tri-sodium citrate functionalized magnetite loaded DOX nanoparticles (DOX/Cit-MNPs). The DOX/Cit-MNPs were coated with chitosan to form chitosan coated citrate functionalized magnetite loaded DOX nanoparticles (Cs/DOX/Cit-MNPs) to offer biodegradability and pH-sensitive drug release features. The Fourier transform infrared spectroscopy (FTIR) analysis confirmed functionalization of SPMNPs, DOX-conjugation, and chitosan coating. The trans electron microscopy (TEM) show spherical nanostructures with average size 40 nm for coated nanocarriers. The saturation magnetization value of carrier was 59 emu/g.The in-vitro release of DOX from the chitosan coated tri-sodium citrate functionalized magnetite loaded DOX nanoparticles (Cs/DOX/Cit-MNPs) was studied to be 75% at pH 5.5 and 28.6% at pH 7.4 which proves the pH sensitivity of encapsulated Cs/DOX/Cit-MNPs. The effect of Cs/DOX/Cit-MNPs toward Human Breast Cancer Cell lines (MCF7) was studied and found to be 76% without magnet and 98% with external magnet after 72 h. With increasing DOX concentration and treatment time, the cell inhibition (IR%) of DOX solution and Cs/DOX-Cit-MNPs suspension to all cells is increased. Cs/DOX/Cit-MNPs showed sustained release and good inhibition to cancer cells and offer a protective mode for normal cells (WISH) compared to the free DOX.

Magnetic resonance imaging (MRI) has attracted increasing attention as a feasible alternative or adjunctive imaging modality for X-ray digital subtraction angiography because of the high tissue resolution and non-ionization radiation. In this study, a one-step electrospray method was developed to fabricate PVA microspheres encapsulated with in situ synthesized Fe3O4 nanoparticles. Fe3O4@PVA microspheres were mono-dispersed black spheres with a wide range of sizes (262-958 µm). The in situ-synthesized Fe3O4 nanoparticles were used as the contrast agent of MRI and the cross-linkers of PVA matrixes for the embolization purpose. In vivo evaluation of renal arteries of normal rabbits showed that Fe3O4@PVA microspheres had good embolic effect and enhanced capability of MRI. In vitro and in vivo biosafety assessment confirmed that Fe3O4@PVA microspheres had favorable biocompatibility. The DOX-loaded Fe3O4@PVA microspheres showed a typical drug-sustained release profile. These results suggest that the prepared DOX-loaded Fe3O4@PVA microspheres have the function of MRI, embolotherapy and chemotherapy. We expect our study could provide a simple and useful approach for the systematic design, fabrication, and application of a new type of magnetic microspheres as a triple-functional embolic agent for the development of MRI-guided TACE. STATEMENT OF SIGNIFICANCE: Due to the low tissue resolution and hazardous ionization radiation of X-ray digital subtraction angiography, it is beneficial to study MR imaging embolic microspheres for the development of MRI-guided TACE. In this study, a one-step electrospray method was firstly developed to fabricate PVA microspheres encapsulated with in situ synthesized Fe3O4 nanoparticles. Then, chemotherapeutic agent (DOX), contrast media of MRI (Fe3O4) and embolic agent (PVA matrix) were combined together in one body (DOX-loaded Fe3O4@PVA microspheres) to achieve the triple effects of chemotherapy, MR imaging and embolization. This triple-functional embolic agent offers potential for the future development of MRI-guided TACE.

Abstract
A glassy carbon electrode modified with multi-walled carbon nanotubes (MWCNTs) decorated with gold nanoparticles has been investigated for the first time as an ultrasensitive electrochemical sensor for the determination of doxorubicin hydrochloride (DOX), an efficient antitumor agent. The developed nanocomposite has been characterized by scanning electron microscopy (SEM), besides cyclic and linear sweep voltammetry electrochemical techniques. An efficient catalytic activity for the reduction of DOX has been demonstrated, leading to a significant increase in peak current density and a remarkable decrease in reduction over-potential. Under the optimal condition, a wide linear DOX concentration range from 1×10-11 to 1×10-6 M with a very low detection limit of 6.5 pM was achieved with the modified electrode. Meanwhile, the functionalized MWCNTs/gold nanoparticles indicated an appropriate selectivity, reproducibility, and repeatability as well as long-term stability. The promising outcomes of this research approved the applicability of the developed nanocomposite sensor towards trace amounts of DOX in pharmaceutical and clinical preparations.

Abstract
In the present work, an innovative electrochemical sensor was fabricated based on poly toluidine blue modified glassy carbon electrode (PTB-GCE). So, PTB-GCE was used for the detection and determination of doxorubicin hydrochloride (DOX) in cell lysate, and whole human plasma samples. PTB could enhance the rate of electrochemical reaction for the electro oxidation and detection of DOX in real samples. Cyclic voltammetry (CV) technique was used for the electro polymerization of toluidine blue on the surface of GCE with the applied potential ranging from -0.6 to 0.2 V. The sensor construction steps were approved by field emission scanning electron microscopy (FE-SEM), Energy dispersive X-ray spectroscopy (EDX) and electrochemical methods. Also, CV results indicated that the DOX is oxidized via two electrons and two protons process at the optimum pH of 6.5 using PTB modified GCE. Under optimized conditions, differential pulse voltammetry (DPV) technique response exhibited linear relationship between the oxidative peak current and concentration of DOX in the range of 17 nM - 8.6 μM with low limit of quantification (LLOQ) of 17 nM for untreated and treated human plasma samples. Also, determination of DOX in MDA-MB-231 and 4T1cell lysates were performed based on its direct electrochemical oxidation on PTB-GCE. Finally, analytical validation of DOX in human bio-fluids using FDA guideline were done successfully. Results suggested that the proposed electrochemical sensor can be used to the sensitive and selective determination of DOX in biological samples. The interaction results of DOX with cancer cells indicate the developed probe can easily detect candidate drug in cancer cells with high accuracy. To the best of our knowledge this is the first report of the determination of DOX based on the direct electrochemical oxidation on PTB-GCE and determination in MDA-MB-231 and 4T1 cell lysates. It is anticipated that this research open new horizons on the design of new class of electrochemical sensors for determination drugs, and therapeutic drug monitoring (TDM) in human bio-fluids.

Abstract
Drug delivery systems for the sustained and target delivery of doxorubicin to tumor cells are a topic of interest due to the efficacy of the doxorubicin in cancer treatment. The use of polymers such as Pluronic is being studied widely for the formulation of doxorubicin hydrochloride. However, the basic understanding of the physicochemical properties of pluronic micelles in presence of doxorubicin hydrochloride is a very essential topic of study. Doxorubicin hydrochloride is fluorescent; this helped us to study its sensitivity towards the Pluronic microenvironment using the fluorescence technique. In this work, the interaction and place of location of doxorubicin hydrochloride in Pluronic F127 and P123 micelles has been studied extensively using steady-state fluorescence intensity, dynamic fluorescence lifetime, quenching studies, dynamic light scattering, and zeta potential measurements, at different Pluronic concentrations. Using a fluorescence quenching experiment, doxorubicin hydrochloride was found to reside near the hydrophilic PEO corona region of the Pluronic micelles. For both the Pluronic, in the concentration range of study, the micellar size was found to be below 30 nm; this may have a greater advantage for various applications.

Abstract
HYPOTHESIS Doxorubicin hydrochloride (DX) is widely used as a chemotherapeutic agent, though its severe side-effects limit its clinical use. A way to overcome these limitations is to increase DX latency through encapsulation in suitable carriers. However, DX has a high solubility in water, hindering encapsulation. The formulation of DX with sodium cholate (NaC) will reduce aqueous solubility through charge neutralization and hydrophobic interactions thus facilitating DX encapsulation into poloxamer (F127) micelles, increasing drug latency. EXPERIMENTS DX/NaC/PEO-PPO-PEO triblock copolymer (F127) formulations with high DX content (DX-PMs) have been prepared and characterized by scattering techniques, transmission electron microscopy and fluorescence spectroscopy. Cell proliferation has been evaluated after DX-PMs uptake in three cell lines (A549, Hela, 4T1). Cell uptake of DX has been studied by means of confocal laser scanning microscopy and flow cytometry. FINDINGS DX-PMs formulations result in small and stable pluronic micelles, with the drug located in the apolar core of the polymeric micelles. Cell proliferation assays show a delayed cell toxicity for the encapsulated DX compared with the free drug. Data show a good correlation between cytotoxic response and slow DX delivery to nuclei. DX-PMs offer the means to restrict DX delivery to the cell interior in a highly stable and biocompatible formulation, suitable for cancer therapy.

Abstract
In recent years, polysaccharide-decorated superparamagnetic iron oxide nanoparticles (SPIONs) have gained attention in the field of “nanotheranostics” with integrated diagnostic and therapeutic functions. Carboxymethyl Assam bora rice starch-stabilized SPIONs (CM-ABRS SPIONs), synthesized by co-precipitation method, has already shown exciting potential towards magnetic drug targeting potential. After establishing it as a promisable targeting carrier, the present study is focused on the next step i.e. to evaluate its In vitro anti-tumor potential by loading anticancer drug “Doxorubicin hydrochloride (DOX)” onto CM-ABRS SPIONs. DOX-loaded CM-ABRS SPIONs were physico-chemically characterized by DLS, zeta-potential, TEM, FT-IR, XRD, and VSM analysis. Spectroflourimetric analysis confirmed the maximum loading of DOX up to 6% (w/w) onto CM-ABRS SPIONs via electrostatic interactions. Further, molecular level drug performance was investigated by docking study against receptors (HER-2 and Folate receptor-α) over expressed in cancer cells and MTT assay (in MCF-7 and HeLa cell line), which conferred promisable results of DOX-CM-ABRS SPIONs as compared to standard DOX solution.

Abstract
The aim of this study was to investigate the impact of different chain length fatty acids on physicochemical properties and cancer targeting of fattigation-platform nanoparticles (NPs). Two different types of fatty acids (short chain, 2-hydroxybutyric acid, C4; long chain, oleic acid, C18:1) were successfully conjugated to human serum albumin (HSA) via simple 1-ethyl-3-(3-dimethylaminopropyl) carbodiimide hydrochloride (EDC) coupling reaction. These conjugates readily formed HSA-C4 and HSA-C18:1 NPs which showed good stability in serum and desirable biocompatibility with normal cell line (HEK293T). Doxorubicin hydrochloride (DOX) was efficiently loaded into NPs by incubation process via electrostatic interaction. The structure, morphology, and texture of DOX-loaded NPs were characterized by Transmission electron microscopy (TEM) equipped with Energy-dispersive X-ray spectroscopy (EDS). The initial burst release of DOX-loaded NPs was controlled by the presence and chain length of fatty acids. In vitro cytotoxicity studies with three cancer cell lines (A549, HT-29, and PANC-1) suggested that fattigation-platform NPs have distinctive cytotoxic effects compared to Doxil®. Confocal microscopy and flow cytometry exhibited that the cellular uptake of DOX-loaded NPs was varied by the different chain lengths of fatty acids. It was evident that the chain length of fatty acids in the fattigation-platform NPs could play a vital role in varying physicochemical properties and cancer cell targeting of NPs.

Abstract
Since Fe3O4 nanoparticles synthesized by plant extracts possess good bio-compatibility and superparamagnetic properties, the possibility of these could be used as a carrier in drug delivery. In this work, doxorubicin hydrochloride (DOX), an anti-cancer drug, loaded on glutaric anhydride-functionalized magnetic nanoparticles (Fe3O4@SiO2-Glu) was investigated at varying pH values for effective drug delivery. Various factors affecting the adsorption of DOX onto the Fe3O4@SiO2-Glu were examined, where the adsorption efficiency of DOX reached 92% at a concentration of 20 mg/L employing 10 mg of Fe3O4@SiO2-Glu at 303 K in pH 7.4. However, the adsorption efficiency of DOX was decreased to 18% at acidic pH value down to 3.0, implicating that the drug releasing process was controlled by pH. Adsorption kinetics was fitting to pseudo-second-order and the isothermal adsorption conformed to Freundlich isotherm. The morphology and surface composition of the synthesized Fe3O4@SiO2-Glu were characterized by SEM, TEM, and N2 adsorption/desorption isotherms, revealing that the specific surface area being 62.6 m2/g and the size ranging from ~30 to 50 nm. The zeta potential results indicated that Fe3O4@SiO2-Glu were negatively charged in various pH from 3 to 8.5. Characterizations by FTIR and UV-Vis techniques suggested that the DOX was absorbed and it can be delivered by Fe3O4@SiO2-Glu.

Abstract
In the current study, we aimed to develop a novel injectable thermosensitive hydrogel for simultaneous intra-tumoral administration of paclitaxel (PTX) and doxorubicin hydrochloride (DOX). At first, mixed micelles composed of Pluronic F127 and α-tocopheryl polyethylene glycol 1000 succinate (TPGS) was loaded with PTX and their physicochemical properties including particle size, zeta potential, drug loading content, entrapment efficiency, and the drug release were investigated in details. In the second step, the optimized PTX-loaded micelles prepared in the first step were incorporated into the thermosensitive Pluronic F127/hyaluronic acid (PF127/HA) hydrogel containing fixed amount of DOX. Gel formation temperature, rheological properties, injectability, degradation rates of the hydrogel, and the release rate of PTX and DOX from the hydrogel were examined. The mean particle sizes and zeta potentials of the PTX-loaded micelles were 157.5 ± 20.1 nm and -9.6 ± 1.1 mV, respectively. The entrapment efficiency of the formulation was about 51%. The hydrogel containing PTX-loaded micelles and DOX existed as a solution with low viscosity at 4 °C converted to a semisolid upon increasing the temperature to 35 °C. DOX was completely released from the hydrogel within 12 h, while 40-80% of PTX could be released from the different formulations during 3 days. This novel thermosensitive hydrogel prepared in the current study could be efficiently used for co-delivery of PTX and DOX in solid tumor types.

Abstract
The present article demonstrates the targeted delivery of doxorubicin hydrochloride to human osteosarcoma cancer cell lines (MG 63) using functionalized dextrin based crosslinked, pH responsive and biocompatible nanogel. The nanogel has been prepared through Michael-type addition reaction using dextrin (Dxt), N, N'-methylene bisacrylamide (MBA, as crosslinker), acrylic acid (AA, as monomer) and potassium persulfate (KPS, as initiator). The structure, composition, morphology of the nanogel have been explored using FTIR and 1H NMR spectroscopy, XRD, TGA, DSC, CHN and AFM analyses. The TEM analysis confirmed that the size of nanogel appeared within 100nm, while DLS study indicates that the diameter of the nanogel remained between 113 and 126nm. The AFM study implied the porous morphology of the synthesized nanogel. The rheological study suggests the gel behaviour of the synthesized nanogel at 37±0.1°C. Difference in% swelling at pH 5.5 and 7.4 indicates pH-responsiveness of the nanogel. The in vitro cytocompatibility results ascertained that the nanogel is non-toxic to human mesenchymal stem cells (hMSCs). In vitro cellular uptake study confirmed that FITC-loaded nanogel can cross the cellular membrane and be well uptake by the cell cytoplasm. The nanogel could efficiently encapsulate doxorubicin hydrochloride (Dox) with the loading efficiency of 27±0.2% after 72h. The Dox-loaded nanogel demonstrates anti-cancer activity towards MG 63 cancer cells and release the encapsulated drug in a controlled way.

To increase the encapsulation efficiency and oral absorption of doxorubicin hydrochloride (DOX), a novel drug delivery system of enoxaparin sodium-PLGA hybrid nanoparticles (EPNs) was successfully designed. By introducing the negative polymer of enoxaparin sodium (ES) to form an electrostatic complex with the cationic drug, DOX, the encapsulation efficiency (93.78%) of DOX was significantly improved. The X-ray diffraction (XRD) results revealed that the DOX-ES complex was in an amorphous form. An in vitro release (pH6.8 PBS) study showed the excellent sustained-release characteristics of DOX-loaded EPNs (DOX-EPNs). In addition, in situ intestinal perfusion and intestinal biodistribution experiments demonstrated the improved membrane permeability and intestinal wall bioadhesion of DOX-EPNs, and caveolin- and clathrin-mediated endocytosis pathways were the main mechanisms responsible. The cytotoxicity of DOX was significantly increased by EPNs in Caco-2 cells, compared with DOX-Sol. Confocal laser scanning microscope (CLSM) images confirmed that the amount of DOX-EPNs internalized by Caco-2 cells was higher than that of DOX-Sol showing that P-glycoprotein-mediated drug efflux was reduced by the introduction of EPNs. The qualitative detection of transcytosis demonstrated the ability of the nanoparticles (NPs) to cross Caco-2 cell monolayers. An in vivo toxicity experiment demonstrated that DOX-EPNs reduced cardiac and renal toxic effects and were biocompatible. An in vivo pharmacokinetics study showed that the AUC(0-t) and t1/2 of DOX-EPNs were increased to 3.63-fold and 2.47-fold in comparison with DOX solution (DOX-Sol), respectively. All these results indicated that the novel EPNs were an excellent platform to improve the encapsulation efficiency of an aqueous solution of this antitumor drug and its oral bioavailability.

Abstract
In this study, we tried coupling the small signal molecules that could intercalate into DNA double helix with hybridization chain reaction (HCR) technique to fabricate a multiple immunosensor. Doxorubicin hydrochloride (DXH) and methylene blue (MB) were used as signal molecules and alpha-fetoprotein (AFP) and carcinoembryonic antigen (CEA) were selected as model biomarkers. The immunosensor mainly consists of three parts as follows: First, two different primary antibodies (Ab1) immobilized on the surface of gold nanoparticles (Au NPs); Second, secondary antibodies (Ab2) conjugated with DNA primer; Third, long DNA concatemers from HCR were used as a carrier to intercalate amounts of signal molecules (DXH or MB). A sandwich immunocomplex was formed among primary antibodies, target biomarkers and secondary antibodies conjugated with DNA primer via specific recognition reaction. Afterwards, DNA concatemers intercalating amounts of DXH or MB were linked to DNA primer via DNA hybridization. Square wave voltammetry (SWV) was employed to record the response signals from electroactive molecules DXH and MB, and two distinguishable signals were obtained, which peak potentials were at about -0.30V (corresponding to MB) and -0.70V (corresponding to DXH, both vs SCE), respectively. The signal intensities of MB and DXH were linearly related to the logarithm of biomarkers concentration in the range of 0.05pgmL-1-25ngmL-1, and the limit of detection were 0.03pgmL-1 for CEA and 0.02pgmL-1 for AFP (at S/N=3), respectively. Furthermore, the immunosensor exhibited a sensitive electrochemical response to biomarkers in human serum samples and the results obtained were in accordance with reference method, indicating the immunosensor can be applied to real sample analysis in clinic diagnosis.

Abstract
In this study, bovine serum albumin (BSA) and chitosan (CS) were used to prepare BSA-CS nanogels by a simple green self-assembly technique. Then the nanogels were successfully used to entrap doxorubicin hydrochloride (DOX) with an entrapment ratio of 46.3%, aiming to realize the slow-release effect and lower the cytotoxicity of DOX. The IC50 values of DOX-loaded BSA-CS (DOX-BSA-CS) and free DOX obtained by MTT assay in SGC7901 cells were 0.22 and 0.05μg/mL, respectively. The cytotoxicity of DOX significantly decreased within 24h after encapsulation by the nanogels, indicating that the loaded drug could slowly release within 24h and the BSA-CS was a good slow release system. The cellular uptake experiments indicated DOX-BSA-CS diffused faster into the cancer cell than the bare drug. The flow cytometry and TUNEL assay proved DOX-BSA-CS could induce a larger apoptosis proportion of gastric cancer cells 7901 than the bare drug and it is promising to be used for curing gastric cancer.

Abstract
Polymersomes represent a promising pharmaceutical vehicle for the delivery of hydrophilic therapeutic agents. However, modification of polymersomes with molecules that confer targeting functions remains challenging because of the strict requirements regarding the weight fractions of the hydrophilic and hydrophobic block polymers. In this study, based on the compatibility between cholesterol and polymeric carriers, polymersomes self-assembled by amphiphilic graft polyphosphazenes were endowed with a targeting function by incorporating the cholesterol-linked aptamer through a simple dialysis method. The aqueous interior of the polymersomes was employed to encapsulate water-soluble doxorubicin hydrochloride. In vivo experiments in tumor-bearing mice showed that the aptamer-anchored vesicle targeted accumulation at the tumor site, favorable penetration through tumor tissue, and incremental endocytosis into tumor cells. Correspondingly, the aptamer-anchored vesicle decreased systemic toxicity and effectively suppressed the growth of subcutaneous MCF-7 xenografts. These findings suggested that vesicles modified with targeted groups via hydrophobic supermolecular interactions could provide a platform for selective delivery of hydrophilic drug. STATEMENT OF SIGNIFICANCE Polymersomes have represented a promising type of pharmaceutical vehicles due to their predominant physical properties. However, it is still a challenge to endow polymersomes with active target function because of strict requirements of the weight fractions of hydrophilic polymer block to hydrophobic one. In this research, by taking advantage of the supermolecular interactions between amphiphilic graft polyphosphazene and cholesterol which was linked to aptamer AS1411, we prepared a targeted functional polymersome (PEP-DOX·HCl-Ap) through a simple method with high loading of water soluble anti-cancer drug doxorubicin hydrochloride. The in vivo experiments in MCF-7 tumor-bearing mice demonstrated several advantages of PEP-DOX·HCl-Ap vesicle such as prolonged circulation time in blood, targeted accumulation at tumor site, permeation through the tumor tissue and incremental endocytosis by tumor cells, which consequently resulted in the significantly improved anti-cancer efficacy. Moreover, this novel polymersome designed in this study has built a research platform to achieve targeted delivery of hydrophilic chemotherapeutics for cancer therapy.

Abstract
Low toxic graphene quantum dot (GQD) was synthesized by pyrolyzing citric acid in alkaline solution and characterized by ultraviolet--visible (UV-vis) spectroscopy, X-ray diffraction (XRD), atomic force microscopy (AFM), spectrofluorimetery and dynamic light scattering (DLS) techniques. GQD was used for electrode modification and electro-oxidation of doxorubicin (DOX) at low potential. A substantial decrease in the overvoltage (-0.56 V) of the DOX oxidation reaction (compared to ordinary electrodes) was observed using GQD as coating of glassy carbon electrode (GCE). Differential pulse voltammetry was used to evaluate the analytical performance of DOX in the presence of phosphate buffer solution (pH 4.0) and good limit of detection was obtained by the proposed sensor. Such ability of GQD to promote the DOX electron-transfer reaction suggests great promise for its application as an electrochemical sensor.

Abstract
Hollow silica nanoparticles of two sizes with and without a folic acid targeting ligand were synthesized. Fickian diffusion of the antitumor drug doxorubicin hydrochloride (DOX) was demonstrated by the produced nanoparticles, achieving a cumulative release of 73% and 45% for 215 nm and 430 nm particles respectively over a period of 500 h. The hollow silica nanoparticles presented a time and dose dependent toxicity, selective to human epithelial colorectal adenocarcinoma (Caco2) cells, over mouse embryonic fibroblast (3T3) cells. At 24h Caco2 cell viability was reduced to 66% using pure hollow silica at a concentration of 50 μg mL(-1), while that of 3T3 cells remained at 94% under the same conditions. The selective cytotoxicity of hollow silica nanoparticles was further enhanced by conjugation of folic acid and incorporation of DOX: at 24h and an equivalent DOX concentration of 0.5 μg mL(-1), viable Caco2 cells were reduced to 45% while 3T3 cells were reduced to 83%. Interestingly the equivalent dose of free DOX was more toxic to 3T3 than to Caco2 cells, reducing the 3T3 viability to 72% and the Caco2 viability to 80%, which is likely due to the presence of the p-glycoprotein pumps in Caco2 cells. Folic acid conjugation served to enhance the viability of both cell lines in this work. Careful optimization of the folate content should further improve the cell specificity of the hollow silica nanoparticles, thus providing a viable targeting platform for cancer therapy.

Abstract
The rising incidence of head and neck cancer and the drawbacks of currently used therapeutic strategies such as salvage surgery followed by adjuvant chemo- or radiotherapy have encouraged pursuits for better therapeutic approaches. This work describes the development and characterization of a PEGylated liposomal nanocarrier encapsulated with trans-resveratrol (Res), a plant stilbenoid, and doxorubicin hydrochloride (Dox), a standard chemotherapeutic agent for treatment of oral squamous cell carcinoma. The two drugs were loaded in liposomes prepared from egg phosphatidylcholine and DSPE-PEG with maximum encapsulation efficiencies of about 80% for each drug achieved at Res to Dox ratio of 2:1. The liposomal suspension was found to be stable with a zeta potential of -30.53 mV and size of approximately 250 nm. Thermal properties and release kinetics of the dual drug loaded liposomes were determined. The nanoformulation was evaluated for its in vitro anticancer efficacy on an oral squamous cell carcinoma cell line (NT8e). The cell uptake mechanism of the liposomal formulation was determined using pharmacological inhibitors for different endocytosis pathways. The combination effect of the two drugs was evaluated in free form and was found to have synergistic effects. The formulation was found to have a higher IC50 value than that of free doxorubicin hydrochloride but was found to have a superior effect on the signaling proteins involved in apoptosis and cell cycle.

Abstract
An amphiphilic anionic polypeptide, methoxypolyethylene glycol-poly (glutamic acid) (mPEG-PGA), was synthesized, characterized and evaluated as a nanocarrier for the cationic anticancer drug doxorubicin hydrochloride (DOX·HCl). The complex self-assembled into nanorods in aqueous solutions via electrostatic interactions and exhibited a superior drug loading content (50.8%) and drug loading efficiency (90.2%). The average major axis of the drug-loaded nanorods was approximately 300nm, as determined by transmission electron microscopy. An in vitro release assay showed that drug-loaded nanorods exhibited pH-sensitivity and sustained release. Haemolysis assays demonstrated that the polypeptide was haemocompatible, and the polypeptide drug carrier significantly reduced the haemolysis ratio of DOX·HCl. The pharmacokinetics study showed that DOX-loaded nanorods significantly prolonged the resident time in blood. An in vitro cytotoxicity study and cellular uptake assays demonstrated that the DOX-loaded nanorods resulted in higher cell proliferation inhibition and a higher level of tumour cell uptake in A549 cells than with free DOX·HCl. The prolonged circulation and enhanced antitumor efficacy of DOX-loaded nanorods shows promise for efficient cancer chemotherapy.

Abstract
Doxorubicin hydrochloride is widely used to treat various types of cancers. Its therapeutic and side effects are well documented. However, the developmental toxicity of doxorubicin has not been previously described. Lethal and sublethal effects on embryo-larval stages of zebrafish in a study of the developmental toxicity of doxorubicin were observed. Zebrafish embryos were exposed to different concentrations (0-100 mg/L) of doxorubicin between 4 and 120 h post fertilization, and zebrafish larvae were exposed to different concentrations (0-200 mg/L) of doxorubicin for 96 h. The markers about the development toxicity of doxorubicin in zebrafish were observed under a stereomicroscope. Higher doxorubicin concentrations mainly caused acute lethal effects, and lower doxorubicin concentrations mainly caused sublethal effects, such as multiple malformations in embryos and larvae. Moreover, with the increase of doxorubicin concentration, the malformation rate increased. The heart rate of embryos was accelerated at lower concentrations of doxorubicin (≤ 10 mg/L) and decelerated at higher concentrations (≥ 25 mg/L). The hatching rate and body length were inhibited at higher concentrations of doxorubicin (≥ 25 mg/L).In conclusion, doxorubicin has serious developmental toxicity and this raises a concern for developmental effects of doxorubicin in clinical practice.

Abstract
Our main aim in the present investigation was to explore the in vitro and in vivo cancer targeting potential of the doxorubicin (DOX) laden d-α-tocopheryl polyethylene glycol 1000 succinate (vitamin E TPGS) tethered surface engineered MWCNTs nanoformulation (DOX/TPGS-MWCNTs) and compare it with pristine MWCNTs and free doxorubicin solution. The developed MWCNTs nanoformulations were extensively characterized by Fourier-transform infrared, Raman spectroscopy, x-ray diffraction, electron microscopy, and in vitro and in vivo studies using MCF-7 cancer cell line. The entrapment efficiency was determined to be 97.2 ± 2.50% (DOX/TPGS-MWCNTs) and 92.5 ± 2.62% (DOX/MWCNTs) ascribed to π-π stacking interactions. The developed formulations depicted the sustained release pattern at the lysosomal pH (pH 5.3). The DOX/TPGS-MWCNTs showed enhanced cytotoxicity, cellular uptake and were most preferentially taken up by the cancerous cells via endocytosis mechanism. The DOX/TPGS-MWCNTs nanoconjugate depicted the significantly longer survival span (44 days, p < 0.001) than DOX/MWCNTs (23 days), free DOX (18 days) and control group (12 days). The obtained results also support the extended residence time and sustained release profile of the drug loaded surface engineered nanotubes formulations in body as compared to DOX solution. Overall we can conclude that the developed MWCNTs nanoconjugate have higher cancer targeting potential on tumor bearing Balb/c mice.

The three domains displayed distinct functions: PEG block chain for prolonged circulation; poly(phenylalanine) domain for stabilizing the nanoparticle construct through hydrophobic/aromatic interactions; and the poly(glutamic acid) domain for providing electrostatic interactions with the cationic drug to be loaded. The copolymer could self-assemble into micellar-type nanoparticles, and DOX was successfully loaded into the interior of nanoparticles by simple mixing of DOX·HCl and the copolymer in the aqueous phase. DOX-loaded mPEG-b-P(Glu-co-Phe) nanoparticles (DOX-NP) had a superior drug-loading content (DLC) (21.7%), a high loading efficiency (almost 98%) and a pH-triggered release of DOX. The size of DOX-NP was ∼140 nm, as determined by dynamic light scattering measurements and transmission electron microscopy. In vitro assays showed that DOX-NP exhibited higher cell proliferation inhibition and higher cell uptake in A549 cell lines compared with free DOX·HCl. Maximum tolerated dose (MTD) studies showed that DOX-NP demonstrated an excellent safety profile with a significantly higher MTD (15 mg DOX kg(-1)) than that of free DOX·HCl (5 mg DOX kg(-1)). The in vivo studies on the subcutaneous non-small cell lung cancer (A549) xenograft nude mice model confirmed that DOX-NP showed significant antitumor activity and reduced side effects, and then enhanced tumor accumulation as a result of the prolonged circulation in blood and the enhanced permeation and retention effect, compared with free DOX, indicating its great potential for cancer therapy.

Abstract
Purpose The effect of water-alcohol Papaver bracteatum Lindl. extract on development of mice oocytes treated with Doxorubicin (dox) was examined in this study. Methods The mice were classified into four groups. Control group, mice injected intraperitoneally (IP) with saline. Extract group alone, mice treated with 200 mg/kg of body weight (bw), IP, twelve consecutive days. Dox group alone, mice were given dox, IP, 10 mg/kg bw. Experimental group treated with extract and dox together. Effect of the extract on the development of mice oocytes treated with dox were evaluated through assisted reproductive technology techniques (ARTs). Results Developmental rate and blastocyst formation was improved by using the extract. A significant increase in in vitro developmental competence in comparison with dox group (P < 0.05) was observed. Conclusions The results of this study indicated that P. bracteatum Lindl. extract could prevent dox toxicity of dox affecting both follicle or oocytes, and therefore it can result in improved embryo development which was observed in mice treated with dox plus P. bracteatum Lindl. compared to mice treated with dox alone.
