Abstract
Cellulose acetate phthalate (CAP)/polyvinyl alcohol (PVA)/polyurethane (PU) nanofibers were synthesized by simple and coaxial electrospinning (ES) processes. Doxorubicin (DOX) and the CoFe2O4 nanoparticles were loaded into the nanofibers. The performance of the prepared nanofibers was investigated for the sustained release of DOX against A541 lung cancer cells under chemotherapy/external magnetic field (EMF) and alternating magnetic field (AMF, hyperthermia treatment) combined methods in both the in vitro and in vivo conditions. The sustained release of DOX from core-shell nanofibers containing 5 wt% cobalt ferrite was obtained within 300, 600 h, at pH of 5.5 and 7.4 without AMF and 168, 360 h, under an alternating magnetic field (AMF). More than 98.3 ± 0.2 % of A549 cancer cells were killed in the presence of core-shell nanofibers containing 100 μg DOX and 5 % cobalt ferrite nanoparticles in the presence of AMF. The flowcytometric results indicated that only 19.1 and 8.85 % cancer cells remained alive under EMF and AMF, respectively. The in vivo results revealed in stopping the growth of tumor volume and decrease in the relative tumor volume up to 0.5 were obtained using magnetic core-shell nanofibers containing 100 μg DOX and 5 % cobalt ferrite nanoparticles in the presence of EMF and AMF, respectively.

A Targeted and pH-Responsive Nano-Graphene Oxide Nanoparticle Loaded with Doxorubicin for Synergetic Chemo-Photothermal Therapy of Oral Squamous Cell Carcinoma. Int J Nanomedicine 2023; 18:3309-3324. [PMID: 37351329 PMCID: PMC10284161 DOI: 10.2147/ijn.s402249] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/24/2023] [Accepted: 06/06/2023] [Indexed: 06/24/2023] Open
Abstract
Purpose Oral squamous cell carcinoma (OSCC) is a malignant disease with serious impacts on human health and quality of life worldwide. This disease is traditionally treated through a combination of surgery, radiotherapy, and chemotherapy. However, the efficacy of traditional treatments is hindered by systemic toxicity, limited therapeutic effects, and drug resistance. Fibroblast activation protein (FAP) is a membrane-bound protease. Although FAP has limited expression in normal adult tissues, it is highly expressed in the tumor microenvironment of many solid cancers - a characteristic that makes it an ideal target for anticancer therapy. In this study, we constructed a nano-drug delivery system (NPF@DOX) targeting FAP to increase the therapeutic efficiency of synergistic chemo-photothermal therapy against OSCC. Methods We utilized PEGylated nano-graphene oxide (NGO) to link doxorubicin (DOX) and fluorescently-labeled, FAP-targeted peptide chains via hydrogen bonding and π-π bonding to enhance the targeting capability of NPF@DOX. The synthesis of NPF@DOX was analyzed using UV-Vis and FT-IR spectroscopy and its morphology using transmission electron microscopy (TEM). Additionally, the drug uptake efficiency in vitro, photo-thermal properties, release performance, and anti-tumor effects of NPF@DOX were evaluated and further demonstrated in vivo. Results Data derived from FT-IR, UV-Vis, and TEM implied successful construction of the NPF@DOX nano-drug delivery system. Confocal laser scanning microscopy images and in vivo experiments demonstrated the targeting effects of FAP on OSCC. Furthermore, NPF@DOX exhibited a high photothermal conversion efficiency (52.48%) under near-infrared radiation. The thermogenic effect of NPF@DOX simultaneously promoted local release of DOX and apoptosis based on a pH-stimulated effect. Importantly, FAP-targeted NPF@DOX in combination with PTT showed better tumor suppression performance in vivo and in vitro than did either therapy individually. Conclusion NPF@DOX can precisely target OSCC, and combined treatment with chemical and photothermal therapy can improve the therapeutic outcomes of OSCC. This method serves as an efficient therapeutic strategy for the development of synergistic anti-tumor research.

Abstract
Unimolecular micelles (UIMs) exhibit promising potential in the precise diagnosis and accurate treatment of tumor tissues, a pressing problem in the field of medical treatment, because of their perfect stability in the complex and variable microenvironment. In this study, porphyrin-based four-armed star-shaped block polymers with narrow molar mass dispersity (Đ = 1.34) were facilely prepared by photocontrolled bromine-iodine transformation reversible-deactivation radical polymerization (BIT-RDRP). A photothermal conversion dye, ketocyanine, was covalently linked onto the PEG and then introduced into the polymers through a "grafting onto" strategy to obtain polymeric nanomaterial, THPP-4PMMA-b-4P(PEGMA-co-APMA)@NIR-800, with dual PTT/PDT function. The resulting polymers could form monodispersed UIMs in the water below critical aggregation concentration, meanwhile maintaining the capacities of singlet oxygen release and photothermal conversion. Importantly, the UIMs displayed excellent biocompatibility while exerting superior PTT and/or PDT therapeutic effects under the irradiation of specific wavelengths of light, according to in vitro cellular experiments, which is expected to become a new hot spot for cancer therapy and anti-tumor research. Overall, stable and powerful UIMs with dual PTT/PDT function is provided, which are expected to be competitive candidates in cancer therapy.

Abstract
Liver fibrosis is a chronic disease resulting from repetitive or prolonged liver injury with limited treatment options. Sorafenib has been reported to be a potential antifibrotic agent; however, its therapeutic effect is restricted because of its low bioavailability and severe adverse effects in the gastrointestinal (GI) tract. In this study, we developed sorafenib-loaded silica-containing redox nanoparticles (sora@siRNP) as an oral nanomedicine to treat liver fibrosis. The designed siRNP were prepared by self-assembly of amphiphilic block copolymers, which possess antioxidant nitroxide radicals as a side chain of the hydrophobic segment and porous silica particles in the nanoparticle core. The silica moieties in the core formed a crosslink between the self-assembling block copolymers to afford stable drug absorption, which could be useful in harsh GI conditions after oral drug administration. Based on in vitro evaluation, sora@siRNP exerted antiproliferative and antifibrotic effects against hepatic stellate cells (HSCs) and low toxicity against normal endothelial cells. A pharmacokinetic study showed that siRNP significantly improved the bioavailability and distribution of sorafenib in the liver. In an in vivo study using a mouse model of CCl4-induced liver fibrosis, oral administration of sora@siRNP significantly suppressed the fibrotic area in comparison to free sorafenib administration. In mice with CCl4-induced fibrosis, free sorafenib administration did not suppress the expression of α-smooth muscle actin; however, mice treated with sora@siRNP showed significantly suppressed expression of α-smooth muscle actin, indicating the inhibition of HSC activation, which was confirmed by in vitro experiments. Moreover, oral administration of free sorafenib induced severe intestinal damage and increased leakage into the gut, which can be attributed to the generation of reactive oxygen species (ROS). Our antioxidant nanocarriers, siRNP, reduced the adverse effects of local ROS scavenging in the GI tract. Our results suggest that sora@siRNP could serve as a promising oral nanomedicine for liver fibrosis.

PEGylated dendritic polyurethane as unimolecular micelles for tumor chemotherapy: Effect of molecular architecture. Int J Pharm 2022; 616:121533.

Abstract
Unimolecular micelles have attracted intense interests as drug carriers for tumor chemotherapy owing to their superior stability in comparison with the self-assembled supramolecular ones. Among them, the dendritic polymers with the polar frameworks could favour the loading of chemotherapeutic drugs rather than the hyperbranched polymers via radical polymerization, by enhancing the interaction with drugs. While the tedious synthesis procedure for dendritic polymers could be simplified with the construction principle on urethane chemistry. Here, the PEGylated dendritic polyurethanes, Ph-DPUGly-PEG and Ph-DPUTEA-PEG, were designed with glycerol or triethanolamine as monomer, respectively. The effect of the molecular architecture of the Ph-DPU-PEGs unimolecular micelles on the controlled drug releasing performance was compared. It was found that the Ph-DPUTEA-PEG with tertiary amine as branching points could efficiently endow the pH-triggered drug release, due to its protonation.

Abstract
Unimolecular micelles have attracted wide attention in the field of drug delivery because of their thermodynamic stability and uniform size distribution. However, their drug loading/release mechanisms at the molecular level have been poorly understood. In this work, the stability and drug loading/release behaviors of unimolecular micelles formed using generation-5 polyamidoamine-graft-poly(carboxybetaine methacrylate) (PAMAM(G5)-PCBMA) were studied by dissipative particle dynamics simulations. In addition, the unimolecular micelles formed using generation-5 polyamidoamine-graft-poly(ethyleneglycol methacrylate) (PAMAM(G5)-PEGMA) were used as a comparison. The simulation results showed that PAMAM(G5)-PCBMA can spontaneously form core-shell unimolecular micelles. The PAMAM(G5) dendrimer constitutes a hydrophobic core to load the doxorubicin (DOX), while the zwitterionic PCBMA serves as a protective shell to improve the stability of the unimolecular micelle. The DOX can be encapsulated into the cavity of PAMAM(G5) at the physiological pH 7.4. The drug loading efficiency and drug loading content showed some regularities with the increase in the drug concentration. At the acidic pH 5.0, the loaded DOX can be released gradually from the hydrophobic core. The comparison of DOX-loaded morphologies between the PAMAM(G5)-PCBMA system and PAMAM(G5)-PEGMA system showed that the former has better monodisperse stability. This work could offer theoretical guidance for the design and development of promising unimolecular micelles for drug delivery.

Abstract
In the present work, we constructed nanoscale graphene oxide (NGO) as a drug nanocarrier to improve the process of tumor-targeted drug releases, promote cellular uptake and accumulation of chemotherapy drugs in tumor tissues, and reduce the toxic effects of chemotherapy drugs on normal cells. Hence, great stability was obtained in the biological solution. Moreover, we designed an effective nanoparticle system for the doxorubicin (DOX) delivery targeting the oral squamous cell carcinoma (OSCC) by mediating the HN-1 (TSPLNIHNGQKL) through hydrogen and π–π bonds. DOX@NGO-PEG-HN-1 showed significantly higher cellular uptakes and cytotoxicity in OSCC cells (CAL-27 and SCC-25), compared to free DOX. Moreover, HN-1 showed considerable tumor-targeting and competition inhibition phenomenon. As we expected, the nanocarrier showed pH-responsive drug release. In total, our study represented a good technique to construct OSCC-targeted delivery of nanoparticles and improve the anticancer medicines’ efficiency.

Abstract
Maximizing the antitumor efficacy of doxorubicin (DOX) with a new drug delivery strategy is always desired in the field of biomedical science. Because the clinical applications of DOX in the treatment of cancer is limited by the side effects related to the dose. Herein, we report the co-loading of DOX and resveratrol (RESV) using an injectable in situ formed sodium deoxycholate hydrogel (Na-DOC-hyd) at the pH of the tumor extracellular microenvironment. The sequential, controlled, and sustained release of RESV and DOX for synergistic antitumor effects was confirmed by entrapping G4.5-DOX in the RESV-loaded Na-DOC hydrogel (Na-DOC-hyd-RESV). The synergistic antitumor activity of Na-DOC-hyd-RESV+G4.5-DOX was assessed on HeLa cell xenograft tumor in BALB/c nude mice. In the MTT biocompatibility assay, both the G4.5 PAMAM dendrimer and Na-DOC-hyd exhibited negligible cytotoxicity up to the highest dose of 2.0 mg mL-1 in HeLa, MDA-MB-231, and HaCaT cells. The release profiles of DOX and RESV from the Na-DOC-hyd-RESV+G4.5-DOX confirmed the relatively rapid release of RESV (70.43 ± 1.39%), followed by that of DOX (54.58 ± 0.62%) at pH 6.5 in the 7 days of drug release studies. A single intratumoral injection of Na-DOC-hyd-RESV+G4.5-DOX maximally suppressed tumor growth during the 28 days of the treatment period. Na-DOC-hyd-RESV+G4.5-DOX did not cause any histological damage in the major visceral organs. Therefore, this Na-DOC-hydrogel for dual drugs (DOX and RESV) delivery at the pH of the tumor extracellular microenvironment is a promising, safe, and effective combination for antitumor chemotherapy.

Improving silymarin oral bioavailability using silica-installed redox nanoparticle to suppress inflammatory bowel disease. J Control Release 2020; 331:515-524. [PMID: 33616078 DOI: 10.1016/j.jconrel.2020.10.042] [Citation(s) in RCA: 30] [Impact Index Per Article: 7.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/29/2020] [Revised: 09/30/2020] [Accepted: 10/21/2020] [Indexed: 12/19/2022]
Abstract
Chronic inflammatory diseases such as inflammatory bowel diseases (IBD), which are strongly related to the overproduction of reactive oxygen species (ROS), have become more threatening to health. Silymarin is an active compound with the effect of expressing anti-inflammatory activity; however, it exhibits poor bioavailability due to the rapid metabolism and secretion, low permeability across the intestinal epithelial cells, and poor water solubility. In this study, we developed silica-containing redox nanoparticles (siRNP) with 50-60 nm in diameter to improve the bioavailability of silymarin by improving its uptake into the bloodstream and delivery to the targeted tissues of the colon. Silymarin-loaded siRNP (SM@siRNP) significantly increased the antioxidant capacity and anti-inflammatory efficacy in vitro by scavenging 2,2-diphenyl-1-picrylhydrazyl free radical and suppressing nitric oxide and pro-inflammatory cytokines as compared to the other treatments such as free silymarin, siRNP, and silymarin-loaded si-nRNP (the control nanoparticle without ROS scavenging property). Orally administered SM@siRNP significantly improved the bioavailability of silymarin and its retention in the colonic mucosa. The anti-inflammatory effects of SM@siRNP were also investigated in dextran sodium sulfate (DSS)-induced colitis in mice and it was observed that SM@siRNP treatment significantly improved the damage in the colonic mucosa of DSS colitis mice as compared to the other treatments. The results in this study indicate that SM@siRNP is a promising nanomedicine for enhancing the anti-inflammatory activity of silymarin and has a high potential for the treatment of IBD.

Abstract
Circulation stability in vivo and stimuli-responsiveness under a tumor microenvironment of the polymeric prodrug micellar drug delivery systems are very critical to improve the tumor therapeutic efficiency. In this study, a series of polyamidoamine (PAMAM)-graft-poly(2-(diethylamino) ethyl methacrylate) (PDEAEMA)-block-poly(betaine sulfonate) (PSBMA) (PDS) unimolecular micelles were prepared via atom transfer radical polymerization. PAMAM served as a hydrophobic core to load the drug, the PDMAEMA segment was a middle layer to provide both thermo- and pH-sensitivity, whereas the PSMBA shell layer was used to improve the stability of the unimolecular micelles. The PDS exhibited a spherical structure with the size of 10-20 nm at pH 7.4. PDS micelles had excellent stability to resist the large volume liquid dilution. Moreover, it exhibited excellent stability in a complex biological microenvironment because of a superhigh antiprotein adhesion capacity of the PSBMA shell layer compared with PAMAM micelles. Drug release studies confirmed that the DOX can remain in the PDS micelles at pH 7.4 and 37 °C, whereas it can rapidly be released when the pH decreases to 5.0 and/or the temperature increases to 40 °C. In vitro studies suggested that the PDS drug delivery system can effectivity induce apoptosis and inhibit the proliferation of cancer cells. In vivo studies suggested that the PDS micelles prolonged the circulation time, decreased the side effects, and increased the antitumor efficacy. Therefore, the prepared PDS micelles are a potential anticancer drug delivery carrier for cancer therapy.

Encapsulation of gadolinium ferrite nanoparticle in generation 4.5 poly(amidoamine) dendrimer for cancer theranostics applications using low frequency alternating magnetic field.

Abstract
Iron oxide-based magnetic resonance imaging (MRI) contrast agents have negative contrast limitations in cancer diagnosis. Gadolinium (Gd)-based contrast agents show toxicity. To overcome these limitations, Gd-doped ferrite (Gd:Fe3O4 (GdIO) nanoparticles (NPs) were synthesized as T1-T2 dual-modal contrast agents for MRI-traced drug delivery. A theranostics GdIO encapsulated in a Generation 4.5 PAMAM dendrimer (G4.5-GdIO) was developed by alkaline coprecipitation. The drug-loading efficiency of the NPs was ∼24%. In the presence of a low-frequency alternating magnetic field (LFAMF), a maximum cumulative doxorubicin (DOX) release of ∼77.47% was achieved in a mildly acidic (pH = 5.0) simulated endosomal microenvironment. Relaxometric measurements indicated superior r1 (5.19 mM-1s-1) and r2 (26.13 mM-1s-1) for G4.5-GdIO relative to commercially available Gd-DTPA. Thus, G4.5-GdIO is promising as an alternative noninvasive MRI-traced cancer drug delivery system.

Abstract
A dual-sensitive drug delivery system (DDS) based on graphene oxide (GO) which is simultaneously loaded with proapoptotic peptides and anticancer drugs was rationally designed and fabricated for cancer synergetic therapy. Specifically, a kind of cell apoptosis peptide (KLAKLAK)2 (KLA) was anchored on the surface of GO via a disulfide bond to obtain GO-SS-KLA. Then, the aromatic anticancer drug doxorubicin (DOX) was loaded on GO through π-π conjugation and hydrogen bonding interactions. Finally, bovine serum albumin (BSA) was used to coat the GO carrier to obtain a biological medium-stable GO-based DDS, DOX@GO-SS-KLA/BSA. The results show that KLA and DOX can be released responding to the reductive and pH stimulus inside the cells, respectively, and achieve a synergetic therapy for cancer. Moreover, the results of stability studies show that DOX@GO-SS-KLA/BSA could be stably dispersed in water for more than 8 days and in 10% fetal bovine serum for at least 6 days. The constructed DOX@GO-SS-KLA/BSA exhibits great potential as a drug carrier for co-delivery of various therapeutic agents.

Abstract
Dendrimers are interesting candidates for various applications because of the high level of control over their architecture, the presence of internal cavities, and the possibility for multivalent interactions. More specifically, zwitterionic dendrimers modified with an equal number of oppositely charged groups have found use in in vivo biomedical applications. However, the design and control over the synthesis of these dendrimers remains challenging, in particular with respect to achieving full modification of the dendrimer. In this work, we show the design and subsequent synthesis of dendrimers that are highly charged while having zero net charge, that is zwitterionic dendrimers that are potential candidates for biomedical applications. First, we designed and fully optimized the synthesis of charge-neutral carboxybetaine and sulfobetaine zwitterionic dendrimers. Following their synthesis, the various zwitterionic dendrimers were extensively characterized. In this study, we also report for the first time the use of X-ray photoelectron spectroscopy as an easy-to-use and quantitative tool for the compositional analysis of this type of macromolecules that can complement techniques such as nuclear magnetic resonance and gel permeation chromatography. Finally, we designed and synthesized zwitterionic dendrimers that contain a variable number of alkyne and azide groups that allow straightforward (bio)functionalization via click chemistry.

Abstract
Unimolecular polymeric micelles are a class of single-molecule amphiphilic core-shell polymeric architectures, where the hydrophobic core is well stabilized by the hydrophilic shell, avoiding intermolecular core-core interactions. Multi-arm copolymers with a dendritic core, as well as hyperbranched and comb-like polymers, can form unimolecular micelles easily. In this review, examples of polymers able to form detectable unimolecular micelles will be presented, summarizing the analytical techniques used to characterize the unimolecular micelles and discriminate them from other supramolecular aggregates, such as multi-micelle aggregates. Unimolecular micelles are suitable for the nanoencapsulation of guest molecules. Compared to traditional supramolecular micelles, unimolecular micelles do not disassemble under dilution and are stable to environmental modifications. Recent examples of their application as drug delivery systems, endowed with increased stability and transport properties, will be discussed.

Abstract
Multifunctional drug carriers have great applications in biomedical field. In this study, we introduced both polydopamine (PDA) and zwitterionic polymer of poly(3-(3-methacrylamidopropyl-(dimethyl)-ammonio)propane-1-sulfonate) (PSPP) onto the surface of mesoporous silica nanoparticles (MSNs) to develop a novel nanoparticle (MSNs@PDA-PSPP), which was employed as a new kind of drug carrier for the delivery of doxorubicin (DOX). The PDA coating, as a gatekeeper, could endow the drug carrier with pH-sensitive drug release performance. The outermost PSPP layer would make the drug carrier possess protein resistance performance. The chemical structure and properties were characterized by Fourier transform infrared spectroscopy (FTIR), transmission electron microscopy (TEM), dynamic light scattering (DLS) and thermogravimetric analysis (TGA). MSNs@PDA-PSPP could keep good colloidal stability within 72 h in phosphate buffered saline (PBS) and protein solutions. Meanwhile, MSNs@PDA-PSPP exhibited a high drug loading for DOX. In vitro drug release experiments suggested MSNs-DOX@PDA-PSPP exhibited pH-dependent drug release behaviors. Besides, MSNs@PDA-PSPP had no cytotoxicity to human hepatocellular carcinoma cells (HepG2 cells) even at a concentration of 125 µg/mL. More importantly, cellular uptake and in vitro anticancer activity tests suggested that MSNs-DOX@PDA-PSPP could be taken up by HepG2 cells and DOX could be successfully released and delivered into the cell nuclei. Taken together, MSNs@PDA-PSPP have great potential in the biomedical field.

Vong LB, Kimura S, Nagasaki Y. Newly Designed Silica-Containing Redox Nanoparticles for Oral Delivery of Novel TOP2 Catalytic Inhibitor for Treating Colon Cancer. Adv Healthc Mater 2017; 6. [PMID: 28736844 DOI: 10.1002/adhm.201700428] [Citation(s) in RCA: 18] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/03/2017] [Revised: 06/13/2017] [Indexed: 01/23/2023]
Abstract
Although oral drug delivery is the most common route of drug administration, the conventional polymeric nanocarriers exhibit a low drug loading capacity and low stability in the gastrointestinal (GI) environments. In this study, a newly designed silica-containing redox nanoparticle (siRNP) with reactive oxygen species (ROS) scavenging capacity is developed as an ideal oral nanocarrier for a novel hydrophobic anticancer compound BNS-22 to treat colitis-associated colon cancer in vivo. Crosslinking of silica moieties significantly enhances the stability under acidic conditions and improves BNS-22 loading capacity of siRNP compared to the conventional redox nanoparticle. After oral administration to mice, BNS-22-loaded siRNP (BNS-22@siRNP) remarkably improves bioavailability and colonic tumor distribution of BNS-22. As the result, BNS-22@siRNP significantly inhibits the tumor progression in colitis-associated colon cancer mice compared to other control treatments. It is noteworthy that no systemic absorption of siRNP carrier is observed after oral administration. Interestingly, orally administered BNS-22@siRNP significantly suppresses the adverse effects of BNS-22 owing to its ROS scavenging capacity, and no other noticeable toxicities are observed in mice treated with BNS-22@siRNP although siRNP is localized in the GI tract. Our results indicate that siRNP is a promising oral drug nanocarrier for cancer therapy.
