Crosslinked and PEGylated Pectin Chitosan Nanoparticles for Delivery of Phytic Acid to Colon. Int J Pharm 2023; 639:122937. [PMID: 37068717 DOI: 10.1016/j.ijpharm.2023.122937] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/27/2023] [Revised: 04/03/2023] [Accepted: 04/04/2023] [Indexed: 04/19/2023]
Abstract
Polysaccharide-based nanoparticles (NPs) such as pectin/ chitosan (PN/CN) had always been of greatest interest because of their excellent solubility, biocompatibility, and higher suitability for oral drug delivery. This study employed blending-crosslinking of polymers (PN&CN) followed by emulsification-solvent evaporation to prepare and compare two sets of PEGylated NPs to deliver phytic acid (IP6) to colon orally as it has potential to manage colon cancer but fails to reach colon when ingested in pure form. The first set was crosslinked with Glutaraldehyde (GE) (GE*PN-CN-NPs) while the second set was crosslinked with sodium tripolyphosphate (TPP) (TPP*PN-CN-NPs). IP6-loaded-GE/TPP*PN-CN-NPs were optimized using a central composite design. Developed TPP*PN-CN-NPs had a smaller size (210.6±7.93nm) than GE*PN-CN-NPs (557.2±5.027nm). Prepared NPs showed <12% IP6 release at pH 1.2 whereas >80% release was observed at pH 7.4. Further, NPs were explored for cytocompatibility in J774.2 cell lines, cytotoxicity, and cellular uptake in HT-29 and DLD-1 cell lines. While exhibiting substantial cytotoxicity and cellular uptake in HT-29 and DLD-1, the NPs were deemedsafe in J774.2. The PEGylated-TPP*PN-CN-NPs showed time-dependent uptake in J774.2 cell lines. Conclusively, the employed NP development method successfully delivered IP6 to colon and may also open avenues for the oral delivery of other drugs to colon.

Abstract
To achieve efficient delivery and precise release of chemotherapy drugs at tumor sites, an active targeting multi-responsive drug delivery platform was developed. Here, doxorubicin hydrochloride (DOX) was loaded onto polydopamine (PDA), which were coated by the cystamine-modified hyaluronic acid (HA-Cys), designated as DOX@PDA-HA (PDH). The combination of PDA and HA-Cys endowed the nanoplatform photothermal conversion, tumor-targeting, and pH/redox/NIR sensitive drug release capacity. Moreover, HA could be degraded by the excess hyaluronidase (HAase) in the tumor microenvironment (TME), promoting DOX release, and further enhancing the effect of chemotherapy. Experimental results demonstrated PDH good biocompatibility, high loading rate, targeted drug delivery, and efficient tumor cell killing ability. This ingenious strategy based on PDH showed huge potential in photothermal/chemotherapy combination treatment of cancer.

Abstract
Developing a universal nanoplatform for efficient delivery of various drugs to target sites is urgent for overcoming various biological barriers and realizing combinational cancer treatment. Nanogels, with the advantages of both hydrogels and nanoparticles, may hold potential for addressing the above issue. Here, a dual-responsive nanogel platform (HPC nanogel) is constructed using β-cyclodextrin-conjugated hyaluronic acid (HA-βCD), polyethyleneimine (PEI), and cisplatin. HA-βCD and PEI compose the skeleton of the nanogel, and cisplatin molecules provide the junctions inside the skeleton, thus affording a multiple interactions-based nanogel. Besides, HA endows the nanogel with hyaluronidase (HAase)-responsiveness, and cisplatin guarantees the glutathione (GSH)-responsive ability, which make the nanogel a dual-responsive platform that can degrade and release the loaded drugs when encountering HAase or GSH. Additionally, the HPC nanogel possesses excellent small-molecule drug and protein loading and intracellular delivery capabilities. Especially, for proteins, their intracellular delivery via nanogels is not hindered by serum proteins, and the enzymes delivered into cells still maintain their catalytic activities. Furthermore, the nanogel can codeliver different cargoes to achieve "cocktail" chemotherapeutic efficacy and realize combination cancer therapy. Overall, the HPC nanogel can serve as a multifunctional platform capable of delivering desired drugs to treat cancer or other diseases.

Abstract
Recombinant human interferon α-2b (rhINF-α-2b), like most proteins, has several shortcomings such as relatively short half-life, low therapeutic index, high circulating drug fluctuations, and rapid degradation which could hinder its effective delivery. Novel electrostatic spray and ion exchange drug-loading techniques were combined to formulate rhINF-α-2b sodium hyaluronate cross-linked porous sustained-release microspheres (rhINF-α-2b-SHCPM), a protein delivery system. The different properties of rhINF-α-2b-SHCPM including the physicochemical nature, in vitro release behavior, and antitumor activity were evaluated. The loading rate (10.31 ± 0.94%) and encapsulation efficiency (89.09 ± 2.37%) of rhINF-α-2b-SHCPM produced acceptable values. The in vitro cumulative release rate of rhINF-α-2b-SHCPM within 24 h was also 86.26 ± 2.11% with a much better sustained release effect. Thus, the half-life (10.763 h) and retention time (14.067 h) of rhIFNα-2b-SHCPM were significantly prolonged with enhanced bioavailability (43,198.387 ng/L*h) and decreased peak concentration (15,266.4 ngL-1) compared with the free rhIFNα-2b protein (0.912 h, 0.952 h, 34,749.048 ng/L*h, and 48,870.2 ngL-1, respectively). The in vitro anti-proliferative activity and in vivo tumor inhibitory rate of rhIFNα-2b-SHCPM also increased by 90 and 55.86%, respectively, compared with the free rhIFNα-2b solution. The findings significantly supported a well-developed protein delivery system with improved sustained release, acceptable bioavailability, and increased antitumor activities. Graphical Abstract.

Redox/pH-Responsive 2-in-1 Chimeric Nanoparticles for the Co-Delivery of Doxorubicin and siRNA. Polymers (Basel) 2021; 13:polym13244362.

Abstract
The co-delivery of chemotherapy drugs and gene-suppressing small interfering RNA (siRNA) show promise for cancer therapy. The key to the clinical realization of this treatment model will be the development of a carrier system enabling the simultaneous delivery (“co-delivery” instead of combinatorial delivery) of chemotherapy and siRNA agents to cancer. In this study, a co-delivery system was developed from two individual components to form one integrated nanovehicle through a redox-sensitive thiol–disulfide bond for the synergistic delivery of chemotherapy and RNA silencing: doxorubicin (Dox)-loaded N,O-carboxymethyl chitosan (NOCC) complex with a thiolated hyaluronic acid (HA-SH) nanocarrier and dopamine (Dopa)-conjugated thiolated hyaluronic acid (SH-HA-Dopa)-coated calcium phosphate (CaP)-siRNA nanocarrier. The 2-in-1 chimeric nanoparticles (NPs) were structurally stable together in the storage environment and in the circulation. This smart system selectively releases Dox and siRNA into the cytosol. Furthermore, equipped with the tumor-targeting component HA, the co-delivery system shows specific targeting and high cellular uptake efficiency by receptor-mediated endocytosis. In summary, these dual-responsive (redox and pH), tumor-targeting smart 2-in-1 chimeric NPs show promise to be employed in functional co-delivery and tumor therapy.

Abstract
Extracellular pH plays vital roles in physiological and pathological processes including tumor metastasis and chemotherapy resistance. Abnormal extracellular pH is known to be associated with various pathological states, such as those in tumors, ischemic stroke, infection, and inflammation. Specifically, dysregulated pH is regarded as a hallmark of cancer because enhanced glycolysis and poor perfusion in most solid malignant tumors create an acidic extracellular environment, which enhances tumor growth, invasion, and metastasis. Close connection between the cell functions with extracellular pH means that precise and real-time measurement of the dynamic change of extracellular pH can provide critical information for not only studying physiological and pathological processes but also diagnosis of cancer and other diseases. This review highlights the recent development of based fluorescent probes for extracellular pH measurement, including design strategies, reaction mechanism and applications for the detection and imaging of extracellular pH.

Abstract
The downsides of conventional cancer monotherapies are profound and enormously consequential, as drug-resistant cancer cells and cancer stem cells (CSC) are typically not eliminated. Here, a targeted theranostic nano vehicle (TTNV) is designed using manganese-doped mesoporous silica nanoparticle with an ideal surface area and pore volume for co-loading an optimized ratio of antineoplastic doxorubicin and a drug efflux inhibitor tariquidar. This strategically framed TTNV is chemically conjugated with folic acid and hyaluronic acid as a dual-targeting entity to promote folate receptor (FR) mediated cancer cells and CD44 mediated CSC uptake, respectively. Interestingly, surface-enhanced Raman spectroscopy is exploited to evaluate the molecular changes associated with therapeutic progression. Tumor microenvironment selective biodegradation and immunostimulatory potential of the MSN-Mn core are safeguarded with a chitosan coating which modulates the premature cargo release and accords biocompatibility. The superior antitumor response in FR-positive syngeneic and CSC-rich human xenograft murine models is associated with a tumor-targeted biodistribution, favorable pharmacokinetics, and an appealing bioelimination pattern of the TTNV with no palpable signs of toxicity. This dual drug-loaded nano vehicle offers a feasible approach for efficient cancer therapy by on demand cargo release in order to execute complete wipe-out of tumor reinitiating cancer stem cells.

Abstract
An intramolecular fluorescence resonance energy transfer (FRET)-based macromolecular theranostic prodrug was designed by directly conjugating Doxorubicin (DOX) as the FRET acceptor onto the naphthalimide side groups in the fluorescent copolymer PPEGMA20-PNAP8 as the FRET energy donor via an acid-labile imine bond, without a fluorogenic linker. The proposed PPEGMA20-PNAP8-DOX theranostic prodrug showed a high DOX content of 24.3% owing to a conjugation efficiency of > 93% under mild conjugation conditions. It could easily self-assemble into unique theranostic nanoparticles with a Dh of 71 nm. The theranostic nanoparticles showed excellent pH-triggered DOX release performance with very low premature drug leakage of 6.3% in normal physiological medium over 129 h, while>91% of the conjugated DOX was released in the acidic tumor intracellular microenvironment. MTT assays indicated the enhanced antitumor efficacy of the proposed theranostic nanoparticles compared with free DOX. Furthermore, because drug release was triggered by pH, orange fluorescence was restored to the blue fluorescence of the backbone copolymer. Such self-tracking pH-responsive colorful fluorescence variations during intracellular drug delivery and release are expected to allow real-time tumor intracellular drug release monitoring and imaging diagnosis.

Abstract
A glutathione-sensitive poly[methacrylic acid- co-poly(ethylene glycol) methyl ether methacrylate] (PMAABACy- co-PEGMA) nanogel with tunable stability has been fabricated through covalent and metal double-cross-linking strategies in response to the differential change of GSH concentration between the inside and outside of tumor cells. Herein, the size-controlled PMAA- co-PEGMA that possessed unique core-shell structure was first obtained via adjusting the length of PEGMA. Furthermore, N, N-bis(acryloyl)cystamine was introduced to endow PMAA- co-PEGMA with glutathione-sensitive property. The PMAABACy- co-PEGMA950 nanogel exhibited reasonable particle size and desired hydrodynamic diameter that was further cross-linked by Fe(III) ions to obtain a double-cross-linked PMAABACy/Fe(III)- co-PEGMA950 vehicle. In this double-cross-linked vehicle, the existence of metal cross-linked structure made this vehicle possess favorable structural stability to restrict the premature leakage of therapeutic drug. The introduction of covalent cross-linked structure synchronously imparted the vehicle with glutathione-sensitive property in response to the high intracellular glutathione concentrations in tumor cells to induce its structural transform for realizing the release of drug. Additionally, a series of in vitro evaluations demonstrated that PMAABACy/Fe(III)- co-PEGMA950 displayed remarkable biocompatibility and glutathione-sensitive release toward anticancer drug in the simulated intracellular environment of tumor tissues. Notably, the drug-loaded PMAABACy/Fe(III)- co-PEGMA950 exhibited excellent anticancer activity against tumor cells. The double-cross-linked PMAABACy/Fe(III)- co-PEGMA950 nanogel therefore is expected to be a promising tumor microenvironment-sensitive platform for delivering chemotherapeutic drugs.

Herein, folic acid (FA) and galactose (GAL) functionalized, core-crosslinked NPs (CC NPs) with dual-targeting and pH/redox-bioresponsive properties were developed based on amphiphilic FA-poly(6-O-methacryloyl-d-galactopyranose)-b-poly[2-(diisopropylamino) ethyl methacrylate-co-pyridyl disulfide methylacrylate] [FA-PMAgGP-b-P(DPA-co-PDEMA), termed as FA-PMgDP] block copolymers, and then investigated for facilitated hepatoma-targeting delivery of doxorubicin (DOX). A series of PMgDP copolymers were synthesized though two-step RAFT copolymerization followed by acid-induced acetal deprotection reaction. Their well-defined chemical structures and compositions were characterized by 1H NMR and gel permeation chromatography. Nano-sized, non-crosslinked PMgDP NPs (PMgDP NC NPs) with sizes of less than 25 nm in aqueous solution were self-assembled via the solvent exchange method, and PMgDP CC NPs were readily prepared in the presence of dithiothreitol. The drug-loading content of PMgDP CC NPs was up to 15.8% and its entrapment efficiency was 89.0%. In normal physiological conditions, 11.6% of DOX was released from DOX-loaded PMgDP CC NPs at 25 h, whereas in analogous intracellular microenvironment, 95.5% was released at 11 h owing to the acid-induced protonation of tertiary amine and reductive cleavage of disulfide bond in the hydrophobic core. In a cellular uptake study, FA and GAL-mediated, active, dual-targeted DOX-loaded FA-PMgDP CC NPs showed a 3.54-fold increase in cellular uptake efficiency to HepG2 cells compared to that of shown by single GAL-targeted, DOX-loaded PMgDP NC NPs. Results of in vitro cytotoxicity study showed that blank FA-PMgDP CC NPs exhibited good biocompatibility, whereas dual-targeting DOX-loaded FA-PMgDP CC NPs increased cell apoptosis. Therefore, the above results indicated that the well-constructed FA-PMgDP CC NPs with multi-synergistic effect may serve as new nanocarriers in the field of precise hepatoma-targeting drug delivery.

Abstract
Cisplatin (CDDP) has been considered as one of the most effective anticancer drugs against cervical cancer, but the lack of selectivity of CDDP to tumor tissues often leads to serious toxic side effects. In this study, CDDP-incorporated Cy5.5-PEG- g-A-HA nanoparticles were prepared to endue CDDP the ability to selectively target tumors and fluorescence imaging in vivo. The nanoparticles exhibited a spherical shape with particle sizes between 216.4 and 281.5 nm and had a pH and Cl- concentration dependence on controlled and sustained CDDP release, which was favorable for nanoparticles to release more drugs at acidic tumor microenvironment. Cell biology experiments demonstrated that the nanoparticles had good biocompatibility and tumor targeting; the nanoparticles could selectively bind and internalize into HeLa cells and induce apoptosis, but lead to less cytotoxicity on NIH3T3 cells. What is more, the nanoparticles could be clearly fluorescent-imaged in vivo and showed an effective accumulation at the tumor site. Antitumor test in vivo displayed that the nanoparticles had good antitumor efficiency and low systemic toxicity which improved the life quality of mice. Hence, the CDDP-incorporated Cy5.5-PEG- g-A-HA nanoparticles were a potential delivery system for targeting delivery of CDDP against cervical cancer.

Abstract
Shell cross-linked (SCL) polymeric prodrug micelles have the advantages of good blood circulation stability and high drug content. Herein, we report on a new kind of pH/redox responsive dynamic covalent SCL micelle, which was fabricated by self-assembly of a multifunctional polymeric prodrug. At first, a macroinitiator PBYP- ss- iBuBr was prepared via ring-opening polymerization (ROP), wherein PBYP represents poly[2-(but-3-yn-1-yloxy)-2-oxo-1,3,2-dioxaphospholane]. Subsequently, PBYP- hyd-DOX- ss-P(DMAEMA- co-FBEMA) prodrug was synthesized by a one-pot method with a combination of atom transfer radical polymerization (ATRP) and a Cu(I)-catalyzed azide-alkyne cycloaddition (CuAAC) reaction using a doxorubicin (DOX) derivative containing an azide group to react with the alkynyl group of the side chain in the PBYP block, while DMAEMA and FBEMA are the abbriviations of N, N-(2-dimethylamino)ethyl methacrylate and 2-(4-formylbenzoyloxy)ethyl methacrylate, respectively. The chemical structures of the polymer precursors and the prodrugs have been fully characterized. The SCL prodrug micelles were obtained by self-assembly of the prodrug and adding cross-linker dithiol bis(propanoic dihydrazide) (DTP). Compared with the shell un-cross-linked prodrug micelles, the SCL prodrug micelles can enhance the stability and prevent the drug from leaking in the body during blood circulation. The average size and morphology of the SCL prodrug micelles were measured by dynamic light scattering (DLS) and transmission electron microscopy (TEM), respectively. The SCL micelles can be dissociated under a moderately acidic and/or reductive microenvironment, that is, endosomal/lysosomal pH medium or high GSH level in the tumorous cytosol. The results of DOX release also confirmed that the SCL prodrug micelles possessed pH/reduction responsive properties. Cytotoxicity and cellular uptake analyses further revealed that the SCL prodrug micelles could be rapidly internalized into tumor cells through endocytosis and efficiently release DOX into the HeLa and HepG2 cells, which could efficiently inhibit the cell proliferation. This study provides a fast and precise synthesis method for preparing multifunctional polymer prodrugs, which hold great potential for optimal antitumor therapy.

Abstract
Introduction A reduction-sensitive CD44-positive tumor-targetable drug delivery system for doxorubicin (DOX) delivery was developed based on hyaluronic acid (HA)-grafted polymers. Materials and methods HA was conjugated with folic acid (FA) via a reduction-sensitive disulfide linkage to form an amphiphilic polymer (HA-ss-FA). The chemical structure of HA-ss-FA was analyzed by ultraviolet spectroscopy, Fourier transform infrared spectroscopy, and 1H nuclear magnetic resonance (NMR) spectroscopy. The molecular weight of HA-ss-FA was determined by high-performance gel permeation chromatography. Blank HA-ss-FA micelles and DOX-loaded micelles were prepared and characterized. The reduction responsibility, cellular uptake, and in vivo biodistribution of HA-ss-FA micelles were investigated. Results DOX-loaded micelles were of high encapsulation efficiency (88.09%), high drug-loading content (22.70%), appropriate mean diameter (100-120 nm), narrow size distribution, and negative zeta potential (-6.7 to -31.5 mV). The DOX release from the micelles was significantly enhanced in reduction environment compared to normal environment. The result of in vitro cytotoxicity assay indicated that the blank micelles were of low toxicity and good biocompatibility and the cell viabilities were >100% with the concentration of HA-ss-FA from 18.75 to 600.00 μg/mL. Cellular uptake and in vivo biodistribution studies showed that DOX-loaded micelles were tumor-targetable and could significantly enhance cellular uptake by CD44 receptor-mediated endocytosis, and the cellular uptake of DOX in CD44-positve A549 cells was 1.6-fold more than that in CD44-negative L02 cells. In vivo biodistribution of HA-ss-FA micelles showed that micelles were of good in vivo tumor targetability and the fluorescence of indocyanine green (ICG)-loaded micelles was 4- to 6.6-fold stronger than free ICG within 6 h in HCCLM3 tumor-bearing nude mice. Conclusion HA-ss-FA is a promising nanocarrier with excellent biocompatibility, tumor targetability, and controlled drug release capability for delivery of chemotherapy drugs in cancer therapy.

Abstract
Conventional wound healing materials suffer from low efficiency, poor mechanical strength, and nontunable properties. Responsive hydrogels are appealing candidates for tissue engineering. Herein, we developed a double-cross-linked hydrogel system composed of hyperbranched PEG-based polymer, comprising pre-cross-linked acetal structure and numerous terminal acrylate groups, which can form hydrogels in situ and can be further strengthened by UV irradiation. The hyperbranched glycidyl methacrylate-co-poly(ethylene glycol) diacrylate polymers (HB-GMA-PEGs) were first synthesized via in situ deactivation enhanced atom transfer radical polymerization (DE-ATRP). A series of pre-cross-linked materials were achieved after postfunctionalization. The material can absorb a high amount of water to form hydrogels, and the gel stiffness was evaluated in detail before and after UV irradiation. The in vitro cytotoxicity experiments were conducted with the resulting materials and have demonstrated their good biocompatibility. The results indicate that this type of hydrogel with high water uptake capacity has appealing potential as a responsive biomaterial for wound closure.

Abstract
Graphene oxide (GO) has shown great potential in drug delivery. However, the aqueous stability, non-specific drug release and slow release rate are major problems of the GO-based drug delivery system. Herein, we for the first time integrate the dispersant, stabilizing agent and active targeting carrier into a novel drug delivery system based on GO/PP-SS-DOX nanohybrids. The redox-sensitive PP-SS-DOX prodrug was obtained by conjugating mPEG-PLGA (PP) with doxorubicin (DOX) via disulfide bond. PEG-FA provided active targeting property for the constructed drug delivery system, GO/PP-SS-DOX/PEG-FA. In this demonstrated system, PP-SS-DOX markedly increases the stability in physiological solutions of GO and guarantees the DOX release in the reductive environment (cancerous cells). And PEG-FA helps target to cancerous tissues and induces FR-mediated endocytosis. In vitro drug release exhibited the obvious reductive sensitivity and the cumulative release amount was up to 90%, while 40% in previous reports within 72 h. The in vitro cytotoxicity of targeting nanohybrids was significantly cytotoxic than that of non-targeting nanohybrids. In vivo results displayed that the as-prepared targeting nanohybrids showed efficacious antitumor effect while it had nearly no systemic adverse toxicity on B16 tumor-bearing mice. Therefore, the in vitro and in vivo results indicate that our constructed GO/PP-SS-DOX/PEG-FA drug delivery system is a promising carrier in cancer therapy.

Abstract
Folate receptor (FR) has proven to be a valuable target for chemotherapy using folic acid (FA) conjugates. However, FA-conjugated chemotherapeutics still have low therapeutic efficacy accompanied with side effects, resulting from complications such as short circulation half-life, limited tumor delivery, as well as high kidney accumulation. Herein, we present a novel FA-conjugated paclitaxel (PTX) prodrug which was additionally conjugated with an Evans blue (EB) derivative for albumin binding. The resulting bifunctional prodrug prolonged blood circulation, enhanced tumor accumulation, and consequently improved tumor therapeutic efficacy. Methods: Fmoc-Cys(Trt)-OH was coupled onto PTX at the 7'-OH position for further synthesis of ester prodrug FA-PTX-EB. The targeting ability was investigated using confocal microscopy and flow cytometry. The pharmacokinetics of this bifunctional compound was also studied. Meanwhile, cell viability was evaluated in normal cells and three cancer cell lines by MTT assay. In vivo therapeutic effect was tested on FR-α overexpressing MDA-MB-231 tumor model. Results: Compared with free PTX, the FA-PTX, PTX-EB and FA-PTX-EB prodrugs increased circulation half-life in mice from 2.19 to 3.82, 4.41, and 7.51 h, respectively. Pharmacokinetics studies showed that the FA-PTX-EB delivered more PTX to tumors than FA-PTX and free PTX. In vitro and in vivo studies demonstrated that FA-EB-conjugated PTX induced potent antitumor activity. Conclusion: FA-PTX-EB showed prolonged blood circulation, enhanced drug accumulation in tumors, higher therapeutic index, and lower side effects than either free PTX or monofunctional FA-PTX and EB-PTX. The results support the potential of using EB for the development of long-acting therapeutics.

Abstract
Magnetic mesoporous silica nanospheres (MMSN) were prepared and the surface was modified with cancer cell-specific ligand folic acid. Calcium carbonate was then employed as acid-activated gatekeepers to cap the mesopores of the MMSN, namely, MMSN-FA-CaCO3. The formation of the MMSN-FA-CaCO3 was proved by several characterization techniques, viz. transmission electron microscopy, zeta potential measurement, Fourier transform infrared spectroscopy, BET surface area measurement, and UV-Vis spectroscopy. Daunomycin was successfully loaded in the MMSN-FA-CaCO3 and the system exhibited sensitive pH stimuli-responsive release characteristics under blood or tumor microenvironment. Cellular uptake by folate receptor (FR)-overexpressing HeLa cells of the MMSN-FA-CaCO3 was higher than that by non-folated-conjugated ones. Intracellular-uptake studies revealed preferential uptake of these nanoparticles into FR-positive [FR(+)] HeLa than FR-negative [FR(-)]A549 cell lines. DAPI stain experiment showed high apoptotic rate of MMSN-FA-DNM-CaCO3 to HeLa cells. The present data suggest that the CaCO3 coating and folic acid modification of MMSN are able to create a targeted, pH-sensitive template for drug delivery system with application in cancer therapy.

Abstract
Novel biocompatible and biodegradable pH/reduction dual-responsive oxidized alginate-doxorubicin (mPEG-OAL-DOX/Cys) prodrug nanohydrogels were designed for tumor-specific intracellular triggered release of anticancer drug DOX by conjugating DOX via acid-labile Schiff base linkage into the PEGylated oxidized alginate (mPEG-OAL) cross-linked with bioreducible disulfide bond. The effect of the complexation with cyclodextrins (α-CD and β-CD) before or after the cross-linking of the mPEG-OAL on the DOX content and controlled release performance was investigated. It was found that the cyclodextrin inclusion complex prodrug nanohydrogels mPEG(CD)-OAL-DOX/Cys, prepared by cross-linking of the mPEG-OAL after complexation with cyclodextrins, exhibited better pH/reduction dual-responsive controlled release performance than the mPEG-OAL-DOX/Cys(CD) ones prepared by cross-linking of the mPEG-OAL before complexation with cyclodextrins, owing to the supramolecular cross-linking of the adjacent pseudopolyrotaxanes. Especially for the cyclodextrin inclusion complex prodrug nanohydrogels mPEG(α-CD)-OAL-DOX/Cys, DOX was released rapidly under lower pH media mimicking the tumor microenvironment and completely released within 48 h, while the premature leakage under the simulated physiological condition was ∼40%, without burst release in both cases. The cellular toxicity and uptake results demonstrated that the mPEG(α-CD)-OAL-DOX/Cys prodrug nanohydrogels possessed similar inhibition against cancer cell growth in comparison with the free DOX and enhanced drug intracellular accumulation.

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
Herein, a multifunctional traceable and ultrasound-responsive drug targeted delivery system based on indocyanine green (ICG) and folic acid (FA) covalently conjugated lipid microbubbles (ILMBs–FA) is proposed. After encapsulation of the anticancer drug resveratrol (RV), the composite (RILMBs–FA) with fluorescence and ultrasound imaging capacity was studied for highly sensitive dual-imaging guided tumor targeted therapy. The resulting RILMBs–FA with an average particle size of 1.32 ± 0.14 μm exhibited good stability and biocompatibility characteristics. The RILMBs–FA featured a high RV loading ratio and the encapsulated RV has been demonstrated to be released from the microbubbles triggered by ultrasound (US) waves. In addition, it was found that the linked FA could facilitate a high cellular uptake of RILMBs–FA via the FA receptor-mediated endocytosis pathway. Compared to free RV and RILMBs, RILMBs–FA with US irradiation demonstrated a more significant tumor cell-killing efficacy mediated by apoptosis in vitro. Eight hours post intravenous injection of RILMBs–FA, the composites showed maximum accumulation in tumorous tissues according to in vivo fluorescence and US images. This ultimately led to the best tumor inhibition effect among all tested drugs under US irradiation. In vivo biosafety evaluations showed that RILMBs–FA featured high biocompatibility characteristics and no significant systemic toxicity over the course of one month. Taken in concert, these results demonstrate the versatility of this drug delivery system with dual-imaging and ultrasound-triggered drug release characteristics for potential future applications in cancer theranostics. Schematic representation of the synthesis of RILMBs–FA and application in tumor therapy.![]()

Abstract
Polymeric delivery vehicles can improve the safety and efficacy of chemotherapy drugs by facilitating preferential tumor delivery. Double hydrophilic block copolymer (DHBC)-based prodrugs are considered as ideal candidates for drug delivery due to the elegant integration of benefits from both structures including polymeric prodrugs' superior protection and minimal premature drug release using covalent links and a DHBC-based "green" self-assembly strategy by a simple stimulus in a pure aqueous phase without the use of any organic solvent. Clearly, the location of drug molecules in the polymeric prodrugs has exerted a significant effect on their therapeutic efficiency. However, there has been no published data so far, to our knowledge, reporting the effect of drug-conjugated sites on its therapeutic efficacy, as well as some basic guidelines that can be followed to direct the future design of polymeric prodrugs. To this end, herein a thermo-sensitive DHBC, poly(N-(2-hydroxypropyl) methacrylamide)-b-poly(N-isopropyl acrylamide) (P(HPMA)-b-P(NIPAAm)), was designed and synthesized by successive reversible addition and fragmentation chain transfer (RAFT) polymerizations, and was chosen as a platform to clarify this issue. An anti-cancer drug, doxorubicin (DOX) was conjugated to the hydrophilic PHPMA block and the temperature-responsive P(NIPAAm) block, respectively, through a pH-liable hydrazone bond to fabricate two different types of polymeric prodrugs with the drug tethered to the micellar hydrophilic PHPMA shell or encapsulated within the hydrophobic P(NIPAAm) core upon temperature elevation above its lower critical solution temperature (LCST). A detailed comparison study was carried out to investigate which structure exhibits better properties and higher therapeutic efficacy in terms of micellar size, stability, cellular uptake, drug loading capacity, drug release behaviors and cell viability. The results showed the self-assembly of both DHBC-based prodrugs into well-dispersed spherical micelles with similar average hydrodynamic diameters (Dh) around 150 nm in phosphate buffer (PBS, pH 7.4) at 37 °C, but a higher drug loading content (DLC), and enhanced pH-mediated drug release, i.e., much accelerated drug release at pH 5.0, while slower at pH 7.4, as well as enhanced cytotoxicity when the drug was conjugated to the hydrophilic shell of the micelles. The guidelines obtained in this study are thus believed to direct the future design and development of polymeric prodrugs for efficient cancer therapy.

Abstract
A novel CD44 receptor targeting and endosome pH-sensitive dual functional hyaluronic acid-deoxycholic acid-histidine (HA-DOCA-His) micellar system was designed for intracellular paclitaxel (PTX) delivery. The HA-DOCA-His micelles exhibited desirable endosome pH (5.0-6.0)-induced aggregation and deformation behavior verified by size distribution, critical micellar concentration, and zeta potential changes. The HA-DOCA-His micelles presented excellent encapsulation efficiency and loading capacity of 90.0% and 18.9% for PTX, respectively. The PTX release from HA-DOCA-His micelles was pH-dependent, with more rapid PTX release at pH 6.0 and 5.0 than those at pH 7.4 and 6.5. The cellular uptake performance of HA-DOCA-His micelles was enhanced comparing with pH-insensitive HA-DOCA micelles by qualitative and quantitative measurements. HA-DOCA-His micelles could be taken up via CD44-receptor mediated endocytosis, transported into endosomes, and triggered drug release to cytoplasm. In vitro cytotoxicity study exhibited PTX-loaded HA-DOCA-His micelles were more active in tumor cell growth inhibition in MCF-7 cells at pH 5.8 than those at pH 6.8 and pH 7.4. A superior antitumor efficacy was demonstrated with HA-DOCA-His micelles in a MCF-7 breast tumor model. These indicated that the dual functional HA-DOCA-His micelles combined targeted intracellular delivery and endosomal release strategies could be developed as a promising nanocarrier for anticancer efficacy improvement of PTX.
