Doxorubicin-galactomannan nanoconjugates for potential cancer treatment. Carbohydr Polym 2024; 342:122356. [PMID: 39048219 DOI: 10.1016/j.carbpol.2024.122356] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/01/2024] [Revised: 05/29/2024] [Accepted: 05/31/2024] [Indexed: 07/27/2024]
Abstract
In this study, we report the synthesis and characterization of pH-responsive nanoconjugates for targeted drug delivery. Galactomannan extracted from D. regia seeds was oxidized to form aldehyde groups, achieving a percentage of oxidation of 25.6 %. The resulting oxidized galactomannan (GMOX) was then copolymerized with PINIPAm-NH2, yielding a copolymer. The copolymer exhibited signals from both GMOX and PNIPAm-NH2 in its NMR spectrum, confirming successful copolymerization. Critical association concentration (CAC) studies revealed the formation of nanostructures, with lower CAC values observed at higher temperatures. The copolymer and GMOX reacted with doxorubicin (DOX), resulting in nanoconjugates with controlled drug release profiles, especially under acidic conditions similar to tumor microenvironments. Cytotoxicity assays demonstrated significant efficacy of the nanoconjugates against melanoma cells with reduced toxicity towards healthy cells. These findings underscore the potential of the pH-responsive nanoconjugates as promising candidates for targeted cancer therapy, offering improved therapeutic efficacy and reduced systemic side effects.

Abstract
Pectin exists extensively in nature and has attracted much attention in biological applications for its unique chemical and physical characteristics. Functionalized pectin, especially pectic conjugates, has given many possibilities for pectin to improve its properties and bioactivity as well as to deliver active molecules. To better exploit this strategy of pectic functionalization, this review presents in detail the structural modifications of pectin, different synthetic methods, and design strategies of pectic conjugates involving both traditional chemical and "green" approaches. Here, the research ideas and applications of pectic prodrugs as well as the development of preparation based on pectic conjugates are reviewed, with emphasis on crosslinking systems of functionalized pectin and nanosystems based on self-assembly techniques. We hope this review will provide comprehensive and valuable information for the functionalization and systematization of the pectic conjugate from synthesis to application.

Abstract
Now-a-days, the polysaccharides are extensively employed for the delivery of small-molecule drugs ascribed to their excellent biocompatibility, biodegradability and modifiability. An array of drug molecules is often chemically conjugated with different polysaccharides to augment their bio-performances. As compared to their therapeutic precursors, these conjugates could typically demonstrate an improved intrinsic solubility, stability, bioavailability and pharmacokinetic profiles of the drugs. In current years, various stimuli-responsive particularly pH and enzyme-sensitive linkers or pendants are also exploited to integrate the drug molecules into the polysaccharide backbone. The resulting conjugates could experience a rapid molecular conformational change upon exposure to the microenvironmental pH and enzyme changes of the diseased states, triggering the release of the bioactive cargos at the targeted sites and eventually minimize the systemic side effects. Herein, the recent advances in pH and enzyme -responsive polysaccharide-drug conjugates and their therapeutic benefits are systematically reviewed, following a brief description on the conjugation chemistry of the polysaccharides and drug molecules. The challenges and future perspectives of these conjugates are also precisely discussed.

Abstract
BACKGROUND AND OBJECTIVE Motivated by the advancements on bioresorbable nanoswimmers, this paper considers the advantages of direct targeting over systemic targeting for smart tumor homing under the general framework of computational nanobiosensing. Nanoswimmers assembled by magnetic nanoparticles can be used as contrast agents to estimate the locations of tumors inside the human body. METHODS Closely observing the response of nanoswimmers (which act as in vivo biosensors) to the tumor-triggered biological gradients and then guiding them through external manipulation, can result in a higher accumulation at the diseased location. Sensor informatics along with data fusion can play a crucial role in such a knowledge-aided targeting process. Specifically, built upon our previous work on direct targeting inspired by the gradient descent optimization, this work is focused on resolving the real-life constraints of in vivo natural computation such as uniformity of the magnetic field and finite life span of the nanoswimmers. To overcome these challenges, we propose a multi-estimate-fusion strategy to obtain a common steering direction for the swarm of nanoswimmers. RESULTS We show through computational experiments (1) that the mean of individual gradient estimations provides the best choice for symmetrical conditions (tumor location in line with the direction of blood flow) while leader-based swarm steering gives the best results for non-symmetrical search space, and (2) that the iterative memory-driven gradient descent optimization detects the target faster compared to the classical memory-less gradient descent and knowledge-less systemic targeting. CONCLUSION Our proposed strategies demonstrate that a clear demarcation between malignant tumors and healthy tissues can be visualized before nanoswimmers are consumed in human vasculature. We believe that our work will help in overcoming the challenges posed by natural in vivo computation for tumor diagnosis at its early stage.

A Photolysis-Assist Molecular Communication for Tumor Biosensing. SENSORS 2022; 22:s22072495.

Abstract
Molecular communication (MC) is a promising bioinspired paradigm for exchanging molecule information among nanomachines. In this paper, we propose a synchronization-assist photolysis MC system that aims to transmit the biosensing signal of the tumor microenvironment, facilitated by mitigating redundant molecules for improved bit error rate (BER) performance. Benefits from biocompatible MC, biosensors could transmit biosensing signals of the tumor in vivo instead of converting them to electrical signals. Due to diffusion motion’s slow and stochastic nature, intersymbol interference (ISI), resulting from previous symbols’ residual information molecules, inevitably occurs in diffusion-based MC. ISI is one of the challenges in diffusion-based MC, which significantly impacts signal detection. Inspired by on–off keying (OOK) modulation, the proposed modulation implements a switch of molecules and light alternatively. The light emitted is triggered by a synchronization signal, and the photolysis reactions could reduce the redundant molecules. An expression for the relevant channel impulse response (CIR) is derived from a hybrid channel model of diffusion and photolysis reaction. In this paper, we implement the maximum posterior estimation scheme to find the optimal decision threshold and analysis the BER performance in terms of different time intervals of the system. Numerical simulations demonstrate that the proposed method can improve the channel capacity and BER performance. We believe that our work may pave the way for MC application in biosensing.

Abstract
pH-Responsive nanoparticles (NPs) have emerged as an effective antitumor drug delivery system, promoting the drugs accumulation in the tumor and selectively releasing drugs in tumoral acidic microenvironment. Herein, we developed a new amphiphilic modified hydroxyethyl starch (HES) based pH-sensitive nanocarrier of antitumor drug delivery. HES was first modified by hydrophilic imidazole and hydrophobic cholesterol to obtain an amphiphilic polymer (IHC). Then IHC can self-assemble to encapsulate doxorubicin (DOX) and form doxorubicin-loaded nanoparticles (DOX/IHC NPs), which displayed good stability for one week storage and acidic sensitive long-term sustained release of DOX. As a result, cancer cell endocytosed DOX/IHC NPs could continuously release doxorubicin into cytoplasm and nucleus to effectively kill cancer cells. Additionally, DOX/IHC NPs could be effectively enriched in the tumor tissue, showing enhanced tumor growth inhibition effect compared to free doxorubicin. Overall, our amphiphilic modified HES-based NPs possess a great potential as drug delivery system for cancer chemotherapy.

Abstract
BACKGROUND Chemotherapeutic drugs used for tumor treatments often show limited efficiency due to their short lifetime, nonspecific delivery, and slow or insufficient intracellular drug release, and also, they can cause severe system or organ toxicity. The development of chemotherapeutic nanomedicines with high efficacy and satisfactory safety still remains a challenge for current tumor chemotherapy. METHODS A novel type of conjugate was synthesized using hydroxyethyl starch (HES) as a carrier while binding doxorubicin (DOX) onto HES backbone through a pH/redox responsive linker containing both disulfide and hydrazone bonds in series. The built conjugates were self-assembled into nanoparticles (NPs) (HES-SS-hyd-DOX NPs) for achieving enhanced antitumor therapy and adequate safety. RESULTS HES-SS-hyd-DOX NPs had a certain ability for the tumor-orientated drug accumulation and were capable of releasing DOX itself rather than DOX derivatives. It was found that the pH/redox responsive linkage enabled the NPs to achieve fast and sufficient intracellular drug release. Based on the tumor-bearing mouse model, antitumor results demonstrated that these NPs were able to inhibit the growth of the advanced tumors with significantly enhanced efficacy when compared to free DOX, and to those conjugate NPs containing only a single responsive or unresponsive bond. Besides, HES-SS-hyd-DOX NPs also showed adequate safety to the normal organs of the treated mice. CONCLUSION The pH/redox responsive linkage in HES-SS-hyd-DOX was found to play a critical role in mediating the drug accumulation and the fast and sufficient intracellular drug release. The HES-exposed surface of HES-SS-hyd-DOX NPs endowed the NPs with long circulation capability and remarkably reduced the DOX-induced side effects.

Abstract
Novel polysaccharide-platinum conjugated polymers bearing alendronate on Portulaca oleracea polysaccharides (PPS) were designed and synthesized. Their chemical structures and properties were characterized by Fourier transform infrared spectroscopy (FT-IR), 1H NMR and 31P NMR spectroscopy, Thermogravimetric analysis (TGA), X-ray powder diffraction (XRD), UV-vis spectrophotometer (UV-vis) and other analysis methods. The results demonstrated that alendronate can be used as the linker of Portulaca oleracea polysaccharides and platinum compounds. Portulaca oleracea polysaccharides-alendronate (PPS-ALN) conjugates exhibited stronger antioxidant ability than PPS. The cytotoxicity assay to cancer cells was tested in vitro, and the Portulaca oleracea polysaccharides-alendronate-platinum (PPS-ALN-Pt) conjugates strongly inhibited the proliferation of cancer cells than PPS and PPS-ALN. The evaluation of complexes affinity toward supercoiled plasmid DNA, displayed a high DNA interaction. Interestingly, the platinum conjugates displayed immunological competence in HeLa cells by cellular immunofluorescence assay. Besides, the cellular platinum accumulation of PPS-ALN-Pt conjugates was higher than that of cisplatin in HeLa cells, implying that the polysaccharide-platinum conjugated polymers might have a synergistically therapeutic application in metal anticancer drug delivery.

Abstract
In the past decades, the vigorous development of nanomedicine has opened up a new world for drug delivery. Hydroxyethyl starch (HES), a clinical plasma volume expander which has been widely used for years, is playing an attracting role as drug carriers. Compared with all other polysaccharides, HES has proven its unique characteristics for drug delivery platforms, including good manufacture practice, biodegradability, biocompatibility, abundant groups for chemical modification, excellent water solubility, and tailorability. In this review, an overview of various types of HES based drug delivery systems is provided, including HES-drug conjugates, HES-based nano-assemblies, HES-based nanocapsules, and HES-based hydrogels. In addition, the current challenges and future opportunities for design and application of HES based drug delivery systems are also discussed. The available studies show that HES based drug delivery systems has significant potential for clinical translation.

Abstract
Polymer-drug conjugates synthesized by binding therapeutic agents to functional polymers have long been a mainstay of prodrugs, while the slow drug release, insufficient efficacy of a single drug, and low selectivity hamper the clinical translation. By rational prodrug design, a targeted dual-acidity-labile polysaccharide-di-drugs conjugate was synthesized by one-pot simultaneous Schiff base and boronic esterification reactions between oxidized dextran (Dex-CHO) and cyclo-(Arg-Gly-Asp-D-Phe-Lys) (c(RGDfK)), doxorubicin (DOX), and bortezomib (BTZ). The polysaccharide-di-drugs conjugate (Dex-g-(DOX+BTZ)/cRGD) self-assembled into micelle with a diameter at around 80 nm and released the drugs simultaneously triggered by the acidic conditions. Dex-g-(DOX+BTZ)/cRGD specifically recognized and entered the cancer cells through the RGD-αvβ3 integrin interplay, selectively released DOX and BTZ in the acidic intracellular microenvironment, and efficiently inhibited the cell proliferation in vitro. More importantly, Dex-DOX/BTZ/cRGD showed higher intratumoral accumulation and better antitumor efficacy in vivo compared with free drugs and non-targeted control prodrug Dex-g-(DOX+BTZ). The findings indicated that this study provided a facile strategy to develop smart polymer-multi-drugs conjugates for targeted cancer chemotherapy.

Abstract
Starch-based nanoparticles (SNPs) have attracted great interest for their ability to encapsulate, protect, and orally deliver bioactive components because of their diverse functionality, high biocompatibility, and environmental friendliness. SNPs can be synthesized with a broad range of particle sizes, ranging from a few nanometers to a few hundred nanometers (approximately 8-448 nm), which is comparable to the dimensions of proteins (1-10 nm), nucleic acids (2 nm wide, 5-100 nm long), viruses (10-500 nm), and cell organelles (5-100 mm). The ability to tune the dimensions and properties of SNPs allows them to be used to construct complexes with various biological entities, thereby altering their functional performance. SNPs can also be used to enhance the solubility of hydrophobic substances and to improve the nutritional attributes of bioactives. For instance, SNPs can be designed to increase the bioavailability of bioactives or to target their delivery to specific regions of the gastrointestinal tract. In this review, we provide an overview of the methods available for preparing SNPs, the application of SNPs for encapsulating and delivering bioactives, and the potential gastrointestinal fate of SNPs.

Abstract
In this work, the new polysaccharide-platinum conjugates of 5-aminosalicylic acid modified lycium barbarum polysaccharide linking platinum compounds were designed in order to construct an anticancer metal drug delivery system. The multiple analysis methods were used to describe the chemical structure and physical properties of the polysaccharide-metal conjugates. The results showed that 5-aminosalicylic acid successfully acted as linker which was covalently bound between polysaccharide and platinum compound. The morphology and rheological properties of polysaccharide have been changed by the formation of conjugates, which exhibited certain inhibition specificity to A549 (human lung cancer cell line). The agarose gel electrophoresis and fluorescence microscopy results demonstrated that such conjugates promoted the unwinding of DNA and could significantly damage the nucleus of A549 cells. Cell cycle analyzing the Pt complex of conjugates could cause intracellular DNA damage and induced G2 phase arrest. So, polysaccharide-platinum conjugates might find a range of applications, for example in metal anticancer drug delivery.

Abstract
Prodrug entrapment into nanocarriers for tumor delivery is a strategy to achieve a valid therapy with high efficiency. The prodrug contains anticancer agents conjugating with functional moieties or ligands so that the active component is released after metabolism in the body or tumor. The advantages of nanosystems for loading prodrugs include high loading, increased prodrug stability, improved bioavailability and enhanced targeting to tumor cells. In the present article, we introduce the prodrug delivery approaches according to nanomedicine and the recent advances in prodrug-loaded nanocarriers. First, we discuss the conceptional design of combined prodrugs and nanocarriers in response to the obstruction in anticancer therapy. Then we describe the cases of prodrug-loaded nanoparticles for cancer treatment during the past 5 years.

Abstract
Objective. To investigate the possible development of radix hedysari polysaccharide as an antiglioma drug, we studied the effect of radix hedysari polysaccharide on glioma cells in vitro and the growth of glioma in nude mice and on the phagocytosis of macrophages in nude mice with glioma. Methods. The effect of radix hedysari polysaccharide on the growth of glioma was studied based on U251 cell line in vitro. The effect of radix hedysari polysaccharide on the growth of glioma was studied in vivo. The growth inhibition rate of radix hedysari polysaccharide on U251 cell line was determined by the MTT assay. The cell cycle of U251 was analyzed by flow cytometry. The expression of cytokines in U251 cells and tumor tissues was detected using PCR. The phagocytosis of macrophages in the serum of glioma nude mice was detected by Giemsa staining. TNF-α signaling pathway proteins in the serum of glioma nude mice were detected by ELISA. Results. Radix hedysari polysaccharide inhibited the growth of U251 cells, induced apoptosis in G1 phase by cell cycle arrest, and facilitated apoptosis in glioma mice by regulating cell cycle. Mice injected with radix hedysari polysaccharide showed delayed tumor growth and grew slowly. Radix hedysari polysaccharide enhanced the phagocytosis of macrophages in glioma nude mice. Radix hedysari polysaccharides could inhibit tumor development by regulating the immune function of tumor mice and affecting the TNF-α signaling pathway. Conclusion. Radix hedysari polysaccharide can effectively inhibit the growth of glioma and affect the TNF-α signaling pathway, thus playing an antiglioma role.

Abstract
Chemo-photothermal combination therapy could achieve synergistically enhanced efficiency against tumors. Nanocarriers with good safety and high efficiency for chemo- photothermal therapy are pressingly needed. A new type of hydroxyethyl starch (HES) based on nanoparticles (NPs) loaded with doxorubicin (DOX) and indocyanine green (ICG) was, thus, developed in this study. DOX-loaded HES conjugates with redox-sensitivity (HES-SS-DOX) were first synthesized and they were then combined with ICG to self-assemble into HES-SS-DOX@ICG NPs with controlled compositions and sizes via collaborative interactions. The optimal HES-SS-DOX@ICG NPs had good physical and photothermal stability in aqueous media and showed high photothermal efficiency in vivo. They were able to fast release the loaded DOX in response to the redox stimulus and the applied laser irradiation. Based on the H22-tumor-bearing mouse model, these NPs were found to tendentiously accumulate inside tumors in comparison to other major organs. The HES-SS-DOX@ICG NPs together with dose-designated laser irradiation were able to fully eradicate tumors with only one injection and one single subsequent laser irradiation on the tumor site during a 14-day treatment period. In addition, they showed almost no impairment to the body. The presently developed HES-SS-DOX@ICG NPs have good in vivo safety and highly efficient anti-tumor capability. These NPs in conjugation with laser irradiation have promising potential for chemo-photothermal cancer therapy in the clinic.

Abstract
Herein, reduction-responsive disintegratable nanoclusters (NCs) were prepared as a novel nanovehicle for targeted drug delivery. The NCs, with a diameter of ∼170 nm, were self-assembled from hydrophobically modified and iRGD decorated hydroxyethyl starch (iRGD-HES-SS-C18). DOX was loaded into the NCs as a model drug. DOX@iRGD-HES-SS-C18 NCs can disintegrate into smaller ones and release DOX under reduction stimuli. Due to the ligand-receptor binding interactions between iRGD and integrin αV, DOX@iRGD-HES-SS-C18 NCs can specifically bind to the cell membranes of HepG-2 and 4T1 cells (integrin αV positive), resulting in enhanced cellular uptake as compared to DOX@HES-SS-C18 NCs. After cellular internalization, the NCs were transported to endosomes/lysosomes in which the reductive environment triggered the disintegration and DOX release. As a consequence, DOX@iRGD-HES-SS-C18 NCs exhibited an enhanced antitumor effect as compared to DOX@HES-SS-C18 NCs and free DOX, in an in vitro antitumor activity study. The reduction-responsive disintegratable NCs reported here were proved to be a safe and efficient nanoplatform, holding significant translation potential for tumor-targeted drug delivery.

Abstract
In this study, we reported a redox-responsive drug delivery system (DDS) based on heparosan and deoxycholic acid conjugates (HSDs) for effective treatment of laryngopharyngeal carcinoma. The amphiphilic HSDs can self-assemble into stable nanoscale micelles in aqueous medium with favorable drug loading capacity for doxorubicin (DOX). The HSD micelles can exhibit glutathione (GSH)-triggered drug release behavior and reach a nearly 100% release rate in a high GSH level (10 mM) environment. Moreover, FaDu cancer cells can internalize HSD micelles by clathrin-mediated endocytosis, which is energy dependent, fast, and effective. The DOX@HSD induced inhibition of FaDu cancer cells can achieve a minimum of 10-fold selectivity relative to that of COS-7 normal cells. Overall, the redox-responsive DDSs show good biocompatibility and are promising in the clinical treatment of laryngopharyngeal carcinoma.

Abstract
The therapeutic potential of the active targeting and acid-sensitive polysaccharide prodrug was investigated. The active targeting of polysaccharide prodrug was based on the specific interaction between cyclo(Arg-Gly-Asp-d-Phe-Lys) peptide (c(RGDfK)) and its receptor αvβ3 integrin overexpressed on the membrane of tumor cells. The cRGD-modified doxorubicin-conjugated hydroxyethyl starch (HES=DOX/cRGD) was synthesized via a one-step Schiff base reaction between oxidized HES, and DOX and c(RGDfK) that achieved an acid-accelerated drug release profile. The targeted polysaccharide prodrug self-assembled into micelle in aqueous environment with a moderate hydrodynamic diameter of 77.1 nm. All data in vitro indicated enhanced cell uptake and elevated cytotoxicity of HES=DOX/cRGD toward human malignant melanoma A375 cells compared with HES=DOX and DOX. Moreover, the smart prodrug also exhibited upregulated accumulation in the tumor, improved antitumor efficacy, and reduced systemic cytotoxicity in vivo. The cRGD-decorated acid-sensitive polysaccharide prodrug was advantageous in both antitumor efficacy and systemic security, showing great prospect in clinical application.

Abstract
Paclitaxel (PTX) is an effective antineoplastic agent and shows potent antitumor activity against a wide spectrum of cancers. Yet, the wide clinical use of PTX is limited by its poor aqueous solubility and the side effects associated with its current therapeutic formulation. To tackle these obstacles, we report, for the first time, α-amylase- and redox-responsive nanoparticles based on hydroxyethyl starch (HES) for the tumor-targeted delivery of PTX. PTX is conjugated onto HES by a redox-sensitive disulfide bond to form HES-SS-PTX, which was confirmed by results from NMR, high-performance liquid chromatography-mass spectrometry, and Fourier transform infrared spectrometry. The HES-SS-PTX conjugates assemble into stable and monodispersed nanoparticles (NPs), as characterized with Dynamic light scattering, transmission electron microscopy, and atomic force microscopy. In blood, α-amylase will degrade the HES shell and thus decrease the size of the HES-SS-PTX NPs, facilitating NP extravasation and penetration into the tumor. A pharmacokinetic study demonstrated that the HES-SS-PTX NPs have a longer half-life than that of the commercial PTX formulation (Taxol). As a consequence, HES-SS-PTX NPs accumulate more in the tumor compared with the extent of Taxol, as shown in an in vivo imaging study. Under reductive conditions, the HES-SS-PTX NPs could disassemble quickly as evidenced by their triggered collapse, burst drug release, and enhanced cytotoxicity against 4T1 tumor cells in the presence of a reducing agent. Collectively, the HES-SS-PTX NPs show improved in vivo antitumor efficacy (63.6 vs 52.4%) and reduced toxicity in 4T1 tumor-bearing mice compared with those of Taxol. These results highlight the advantages of HES-based α-amylase- and redox-responsive NPs, showing their great clinical translation potential for cancer chemotherapy.

J Control Release 2017; 256:170-181. [PMID: 28414151 DOI: 10.1016/j.jconrel.2017.04.020] [Citation(s) in RCA: 102] [Impact Index Per Article: 14.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/15/2017] [Revised: 03/17/2017] [Accepted: 04/12/2017] [Indexed: 01/05/2023]
Abstract
The purpose of the present study was to identify an "easy-to-adopt" strategy to enhance immune responses using functionalized alginate (ALG) nanoparticles (MAN-ALG/ALG=OVA NPs), which were prepared by CaCl2 cross-linking of two different types of ALG. The mannose (MAN) modified ALG (MAN-ALG) was used for dendritic cell targeting. The other component, composed of ovalbumin (OVA), a model antigen, is conjugated to ALG (ALG=OVA) via pH sensitive Schiff base bond. Grafting of alginate was demonstrated by FT-IR and 1H NMR, while the morphological structure, particle size, Zeta potential of MAN-ALG/ALG=OVA NPs were measured using TEM and DLS. The OVA releasing behavior of MAN-ALG/ALG=OVA NPs was determined as a function of pH. Antigen uptake was examined by flow cytometry and confocal laser scanning microscopy in vitro using mouse bone marrow dendritic cells (BMDCs). The results showed that MAN-ALG/ALG=OVA NPs facilitated antigen uptake of BMDCs and cytosolic release of the antigen. Significant up-regulation of cytokine secretion and expression levels of the surface co-stimulatory molecules were also observed in MAN-ALG/ALG=OVA NPs-treated BMDCs, compared to free OVA. In vivo bio-distribution study using Cy7 (a near-infrared fluorescence dye) labeled MAN-ALG/ALG=OVA NPs showed efficient in vivo trafficking of the nanoparticles from the injection site to the draining lymph nodes. Moreover, MAN-ALG/ALG=OVA NPs were found to enhance cross-presentation of OVA to B3Z T cell hybridoma in vitro. Subcutaneous administration of MAN-ALG/ALG=OVA NPs also induced major cytotoxic T lymphocytes (CTL) response and inhibition of E.G7 tumor growth in C57BL/6 mice. In summary, we report here that the MAN-ALG/ALG=OVA NPs have the potential as a potent nanovaccine for cancer immunotherapy.

Abstract
Doxorubicin (DOX), a kind of wide-spectrum chemotherapeutic drug, can cause severe side effects in clinical use. To enhance its antitumor efficacy while reducing the side effects, two kinds of nanoparticles with desirable compositions and properties were assembled using optimally synthesized hydroxyethyl starch-grafted-polylactide (HES-g-PLA) copolymers and utilized as partner nanocarriers. The large empty HES-g-PLA nanoparticles (mean size, ca. 700 nm), at an optimized dose of 400 mg/kg, were used to block up the reticuloendothelial system in tumor-bearing mice 1.5 h in advance, and the small DOX-loaded HES-g-PLA nanoparticles (mean size, ca. 130 nm) were subsequently applied to the mice. When these partner nanocarriers were administered in this sequential mode, the released DOX had a significantly prolonged plasma half-life time and much slower clearance rate as well as a largely enhanced intratumoral accumulation as compared to free DOX. In vivo antitumor studies demonstrated that the DOX-loaded HES-g-PLA nanoparticles working together with their partner exhibited remarkably enhanced antitumor efficacy in comparison to free DOX. In addition, these HES-g-PLA partner nanocarriers showed negligible damage to the normal organs of the treated mice. Considering safe and efficient antitumor performance of DOX-loaded HES-g-PLA nanoparticles, the newly developed partner nanocarriers in combination with their administration mode have promising potential in clinical cancer chemotherapy.

Abstract
Doxorubicin (DOX) is one of the most potent anticancer agents in cancer chemotherapy, but the clinical use of DOX is restricted by its severe side effects caused by nonspecific delivery. To alleviate the side effects and improve the antitumor efficacy of DOX, a novel redox-sensitive hydroxyethyl starch-doxorubicin conjugate, HES-SS-DOX, with diameter of 19.9 ± 0.4 nm was successfully prepared for tumor targeted drug delivery and GSH-mediated intracellular drug release. HES-SS-DOX was relatively stable under extracellular GSH level (∼2 μM) but released DOX quickly under intracellular GSH level (2-10 mM). In vitro cell study confirmed the GSH-mediated cytotoxicity of HES-SS-DOX. HES-SS-DOX exhibited prolonged plasma half-life time and enhanced tumor accumulation in comparison to free DOX. As a consequence, HES-SS-DOX exhibited better antitumor efficacy and reduced toxicity as compared to free DOX in the in vivo antitumor activity study. The redox-sensitive HES-SS-DOX was proved to be a promising prodrug of DOX, with clinical potentials, to achieve tumor targeted drug delivery and timely intracellular drug release for effective and safe cancer chemotherapy.
