Colloids Surf B Biointerfaces 2024; 242:114085. [PMID: 39018910 DOI: 10.1016/j.colsurfb.2024.114085] [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: 02/19/2024] [Revised: 07/06/2024] [Accepted: 07/09/2024] [Indexed: 07/19/2024]
Abstract
Cisplatin is a widely-used chemotherapeutic agent for the treatment of various solid neoplasms including colon cancer. Cisplatin-induced DNA damage is restricted due to dose-related adverse reactions as well as primary resistance mechanisms. Therefore, it is imperative to utilize novel therapeutic approaches to circumvent cisplatin limitations and attenuate its normal tissues toxicity. In this study, we exploited a novel PEGylated liposomes with greater efficiency to treat colon cancer. For this, an organoselenium compound (diselanediylbis decanoic acid (DDA)) was synthesized, and liposomes composed of Egg PC or HSPC, as well as DOPE, mPEG2000-DSPE, cholesterol and DDA at varying molar ratios were prepared by using thin-film method. Cisplatin loading was performed through incubation with liposomes. Characterization of nanoliposomes indicated a favarable size range of 91-122 nm and negative zeta potential of -9 to -22 mv. The organoselenium compound significantly improved cisplatin loading efficiency within the liposomes (83.4 %). Results also revealed an efficient bioactivity of cisplatin liposome on C26 cells compared to the normal cells. Further, DDA bearing liposomes significantly improved drug residence time in circulation, reduced toxicity associated with the normal tissues, and enhanced drug accumulation within the oxidative tumor microenvironment. Collectively, results indicated that cisplatin encasement within liposomes by using this method could significantly improve the therapeutic efficacy in vivo, and merits further investigations.

Abstract
Polysaccharides (PSAs) are carbohydrate-based macromolecules widely used in the biomedical field, either in their pure form or in blends/nanocomposites with other materials. The relationship between structure, properties, and functions has inspired scientists to design multifunctional PSAs for various biomedical applications by incorporating unique molecular structures and targeted bulk properties. Multiple strategies, such as conjugation, grafting, cross-linking, and functionalization, have been explored to control their mechanical properties, electrical conductivity, hydrophilicity, degradability, rheological features, and stimuli-responsiveness. For instance, custom-made PSAs are known for their worldwide biomedical applications in tissue engineering, drug/gene delivery, and regenerative medicine. Furthermore, the remarkable advancements in supramolecular engineering and chemistry have paved the way for mission-oriented biomaterial synthesis and the fabrication of customized biomaterials. These materials can synergistically combine the benefits of biology and chemistry to tackle important biomedical questions. Herein, we categorize and summarize PSAs based on their synthesis methods, and explore the main strategies used to customize their chemical structures. We then highlight various properties of PSAs using practical examples. Lastly, we thoroughly describe the biomedical applications of tailor-made PSAs, along with their current existing challenges and potential future directions.

Abstract
Throughout the world, oral cancer is a common and aggressive malignancy with a high risk of morbidity, mortality, and recurrence. The importance of early detection in cancer prevention and disease treatment cannot be overstated. Conventional therapeutic strategies have minor difficulties but considerable side effects and unfavourable consequences in clinical applications. Hence, there is a requirement for effective ways for early detection and treatment of oral cancer. At present, numerous forms of nanoparticles have piqued researchers' interest as a potentially useful tool for diagnostic probes and medicinal devices. Because of their inherent physicochemical properties and customizable surface modification, they are able to circumvent some of restrictions and accomplish the intended diagnostic and therapeutic impact. Nanotechnology is a unique field that has revolutionised the industry and is paving the way for new treatments for oral cancer. It can help with a better diagnosis with less harmful substances and is setting current guidelines for treatment. The use of nanotechnology in cancer diagnosis, therapy, and care improves clinical practise dramatically. The different types of nanoparticles that have been developed for the diagnosis and therapy of oral cancers will be covered in this study. The difficulties and potential uses of nanoparticles in the treatment and diagnosis of oral cancer are then highlighted. In order to emphasise existing difficulties and potential remedies for oral cancer, a prospective view of the future is also provided.

Abstract
We report on the morphological transitions of didodecyldimethylammonium bromide (DDAB) cationic vesicles and hybrid DDAB/hyaluronic acid (HA) vesicles upon addition of BSA at pH 7 where BSA is overall negatively charged. Small angle neutron scattering (SANS) is used to extract the size distributions of the nanovesicles, the thickness of the DDAB bilayers and their lamellarity. Although the HA-decorated DDAB vesicles contain the negatively charged polysaccharide the interaction with BSA appears to be more intense in comparison to bare vesicles. Characteristic peaks in the SANS patterns indicate the presence of multilamellar interfaces while the formation of multilamellar vesicles induced by BSA depends on the amount of added HA. Consequently, higher lamellarities are observed at higher BSA contents. This work demonstrates a simple methodology to tune the encapsulation of globular proteins in vesicular nanoassemblies by affecting their lamellarity and has direct implications on the application of vesicles and liposomes in protein delivery.

Abstract
The limitations of traditional cancer treatments are driving the creation and development of new nanomedicines. At present, with the rapid increase of research on nanomedicine in the field of cancer, there is a lack of intuitive analysis of the development trend, main authors and research hotspots of nanomedicine in the field of cancer, as well as detailed elaboration of possible research hotspots. In this review, data collected from the Web of Science Core Collection database between January 1st, 2000, and December 31st, 2021, were subjected to a bibliometric analysis. The co-authorship, co-citation, and co-occurrence of countries, institutions, authors, literature, and keywords in this subject were examined using VOSviewer, Citespace, and a well-known online bibliometrics platform. We collected 19,654 published papers, China produced the most publications (36.654%, 7204), followed by the United States (29.594%, 5777), and India (7.780%, 1529). An interesting fact is that, despite China having more publications than the United States, the United States still dominates this field, having the highest H-index and the most citations. Acs Nano, Nano Letters, and Biomaterials are the top three academic publications that publish articles on nanomedicine for cancer out of a total of 7580 academic journals. The most significant increases were shown for the keywords "cancer nanomedicine", "tumor microenvironment", "nanoparticles", "prodrug", "targeted nanomedicine", "combination", and "cancer immunotherapy" indicating the promising area of research. Meanwhile, the development prospects and challenges of nanomedicine in cancer are also discussed and provided some solutions to the major obstacles.

Abstract
Cluster of differentiation 44 (CD44) is a cell surface glycoprotein overexpressed in varieties of solid tumors including pancreatic, breast, ovary, brain, and lung cancers. It is a multi-structural glycoprotein of the cell surface which is majorly involved in cell proliferation, cell-to-cell interaction, cellular migration, inflammation, and generation of immune responses. Numerous studies focus on the development of nanocarriers for active targeting of the CD44 receptor to improve efficacy of targeting chemotherapy and achieve precise chemotherapy by defining the release, uptake, and accumulation of therapeutic agents. The CD44 receptor has a selective binding affinity towards hyaluronic and chondroitin sulfate (CS). Taking this into consideration, this review focused on the role of CD44 in cancer and its therapy using several nanocarriers such as polymeric/non-polymeric nanoparticles, dendrimer, micelles, carbon nanotubes, nanogels, nanoemulsions etc., for targeted delivery of several chemotherapeutic molecules and nucleic acid. This review also illuminates the role of hyaluronic acid (HA) in cancer therapy, interaction of HA with CD44, and various approaches to target CD44-overexpressed neoplastic cells.

Abstract
Oral cancer is a common malignant life-threatening tumor. Despite some advances in traditional therapy, mortality and mobidity rates are high due to delayed diagnosis and ineffective treatment. Additionally, some patients inevitably suffer from various fatal adverse effects during the course of therapy. Therefore, it is imperative to develop novel methods to eradicate oral cancer cells with minimal adverse effects on normal cells. Nanotechnology is a promising and novel vehicle for the diagnosis and treatment of oral cancer with encouraging recent achievements. In this review, we present state-of-the-art nanotechnology-based drug delivery systems employed in the domain of oral cancer, especially for its enhanced diagnosis and therapy. We describe in detail the types of nanotechnology used in the management of oral cancer and summarize administration routes of nanodrugs. Finally, the potential and prospects of nanotechnology-based drug delivery systems as promising modalities of diagnosis and therapy of oral cancer are highlighted.

Abstract
T‑2 toxin is a type A trichothecene mycotoxin. In order to reduce the side effects of T‑2 toxin and increase the tumor targeting ability, a pH‑sensitive liposome of T‑2 toxin (LP‑pHS‑T2) was prepared and characterized in the present study. The cytotoxicity of LP‑pHS‑T2 on A549, Hep‑G2, MKN‑45, K562 and L929 cell lines was tested by 3‑(4,5‑dimethylthiazolyl‑2)‑2,5‑diphenyltetrazolium bromide assay, with T‑2 toxin as the control. The apoptotic and migratory effects of LP‑pHS‑T2 on Hep‑G2 cells were investigated. The preparation process of LP‑pHS‑T2 involved the following parameters: Dipalmitoyl phosphatidylcholine: dioleoylphosphatidylethanolamine, 1:2; total phospholipid concentration, 20 mg/ml; phospholipid:cholesterol, 3:1; 4‑(2‑hydroxyethyl)‑1‑piperazineethanesulfonic acid buffer (pH 7.4), 10 ml; drug:lipid ratio, 2:1; followed by ultrasound for 10 min and extrusion. The encapsulation efficiency reached 95±2.43%. The average particle size of LP‑pHS‑T2 after extrusion was 100 nm; transmission electron microscopy showed that the shape of LP‑pHS‑T2 was round or oval and of uniform size. The release profile demonstrated a two‑phase downward trend, with fast leakage of T‑2 toxin in the first 6 h (~20% released), followed by sustained release up to 48 h (~46% released). From 48‑72 h, the leakage rate increased (~76% released), until reaching a minimum at 72 h. When LP‑pHS‑T2 was immersed in 0.2 mol/l disodium phosphate‑sodium dihydrogen phosphate buffers (pH 6.5), the release speed was significantly increased and the release rate reached 91.2%, demonstrating strong pH sensitivity. Overall, antitumor tests showed that LP‑pHS‑T2 could promote the apoptosis and inhibit the migration of Hep‑G2 cells. The present study provided a new approach for the development of T‑2 toxin‑based anti‑cancer drugs.

Abstract
Cancer has become a significant public health problem with high disease burden and mortality. At present, radiotherapy and chemotherapy are the main means of treating cancer, but they have shown serious safety problems. The severity of this problem has caused further attention and research on effective and safe cancer treatment methods. Polysaccharides are natural products with anti-cancer activity that are widely present in a lot of plants, and many studies have found that inducing apoptosis of cancer cells is one of their important mechanisms. Therefore, this article reviews the various ways in which plant polysaccharides promote apoptosis of cancer cells. The major apoptotic pathways involved include the mitochondrial pathway, the death receptor pathway, and their upstream signal transduction such as MAPK pathway, PI3K/AKT pathway, and NF-κB pathway. Moreover, the paper has also been focused on the absorption and toxicity of plant polysaccharides with reference to extant literature, making the research more scientific and comprehensive. It is hoped that this review could provide some directions for the future development of plant polysaccharides as anticancer drugs in pharmacological experiments and clinical researches.

Abstract
Malignant melanoma is a highly aggressive skin cancer responsible for 80% of mortality, and the overall median survival in patients with metastatic melanoma is only 6-9 months. Combination treatment through the simultaneous administration of dual drugs in a single nanocarrier has been demonstrated to be elegant and effective in combatting cancer. Herein, we employ a combination therapy based on dacarbazine (DBZ), FDA approved drug for melanoma and all-trans retinoic acid (ATRA), promising anticancer agents loaded on lipid nanoformulations (RD-LNF) as a new treatment strategy for malignant melanoma. We have successfully encapsulated both the drugs in lipid nanoformulations and showed a controlled release of payload over time. We demonstrated that the simultaneous delivery of DBZ and ATRA could effectively reduce cell proliferation in a concentration-dependent manner. The combinational nanoparticles significantly reduced the colony formation ability of B16F10 melanoma cells. Flow cytometer analysis showed that RD-LNF induced a greater proportion of apoptosis cells with significant inhibition of cell cycle progression and cell migration. These results suggest the promising potential of RD-LNF in the treatment of malignant melanoma with high efficacy.

Abstract
Cancer has been a threat to human health, so its treatment is a huge challenge to the present medical field. One of commonly used methods is the controlled release of anticancer drug to reduce the dose for patients, increase the stability of drug treatment and minimize side effects. Cyclodextrin is a kind of cyclic oligosaccharide produced by amylase hydrolysis. Because cyclodextrin contains a cavity structure and active hydroxyl groups, it has a positive effect on the study of the controlled release of anticancer drugs. This article reviews the controlled release of current anticancer drugs based on cyclodextrins as a "flexible switch", and discusses the classification of different types of release systems, highlighting their role in cancer treatment. Moreover, the opportunities and challenges of cyclodextrin as a magic switch in the controlled release of anticancer drugs are discussed.

Abstract
Cancer is the disease with the highest mortality rate, which poses a great threat to people's lives. Cancer caused approximately 3.4 million death worldwide annually. Surgery, chemotherapy and radiotherapy are the main therapeutic methods in clinical practice. However, surgery is only suitable for patients with early-stage cancers, and chemotherapy as well as radiotherapy have various side effects, both of which limit the application of available therapeutic methods. In 1965, liposome was firstly developed to form new drug delivery systems given the unique properties of nanoparticles, such as enhanced permeability and retention effect. During the last 5 decades, liposome has been widely used for the purpose of anticancer drug delivery, and several advances have been made regarding liposomal technology, including long-circulating liposomes, active targeting liposomes and triggered release liposomes, while problems exist all along. This review introduced the advances as well as the problems during the development of liposomal nanosystems for cancer therapy in recent years.

Abstract
In this study, D-alpha-tocopheryl polyethylene glycol-1000 succinate (TPGS)-coated docetaxel-loaded liposomes were developed to reverse multidrug resistance (MDR) and enhance lung cancer therapy. Evaluations were performed using human lung cancer A549 and resistant A549/DDP cells. The reversal multidrug resistant effect was assessed by P-gp inhibition assay, cytotoxicity, cellular uptake, and apoptosis assay. The tumor xenograft model was built by subcutaneous injection of A549/DDP cells in the right dorsal area of nude mice. The tumor volumes and body weights were measured every other day. The TPGS-coated liposomes showed a concentration- and time-dependent cytotoxicity and significantly enhanced the cytotoxicity of docetaxel in A549/DDP cells. Confocal laser scanning images indicated that higher concentrations of coumarin-6 were successfully delivered into the cytoplasm, and the TPGS-coated liposomes enhanced intracellular drug accumulation by inhibiting overexpressed P-glycoprotein. The TPGS-coated liposomes were shown to induce apoptosis. Furthermore, in vivo anti-tumor studies revealed that TPGS-coated docetaxel-loaded liposomes had outstanding anti-tumor efficacy in an A549/DDP xenograft model. The TPGS-coated liposomes, compared with PEG-coated liposomes, showed significant advantages in vitro and in vivo. The TPGS-coated liposomes were able to reverse MDR and enhance lung cancer therapy.

Abstract
In this work, we have successfully designed and formulated a doxorubicin-loaded polypeptide-based multilayer assembled gold nanorod (DH-GNR). We have hypothesized that near-infrared (NIR) laser irradiation of DH-GNR will combine the benefits of chemotherapy and photothermal therapy. The GNR was surface functionalized with poly-glutamic acid (PGA) and poly-l-Lysine (PLL) with a final layer of hyaluronic acid (HA) that could also serve as a targeting ligand toward the overexpressed CD44 receptors in ovarian cancer cells. The zigzag ζ potential of nanoparticle is a proof of successful assembly of alternative polymers on the GNR surface. NIR irradiation exhibited a burst release of drug in pH 7.4 and pH 5.0 buffer conditions. The combination of doxorubicin (DOX)-based chemotherapy and GNR-based photothermal therapy exhibited a synergistic effect in killing the SKOV3 cancer cells. DH-GNR(+NIR) induced a 82.5% apoptosis (combined early and late apoptosis) compared with only 35.2 and 38.5% for DOX or DH-GNR(-NIR) treated cell group. Results clearly suggest that the excessive reactive oxygen species (ROS) generation in DH-GNR (+NIR) might be responsible for the cell apoptosis and cell death. The promising anticancer effect of DH-GNR will be of great potential in the treatment of ovarian cancers and worth further development for treating other malignant tumors.

Abstract
In recent decades, many novel methods by using nanoparticles (NPs) have been investigated for diagnosis, drug delivery and treatment of cancer. Accordingly, the potential of NPs as carriers is very significant for the delivery of anticancer drugs, because cancer treatment with NPs has led to the improvement of some of the drug delivery limitations such as low blood circulation time and bioavailability, lack of water solubility, drug adverse effect. In addition, the NPs protect drugs against enzymatic degradation and can lead to the targeted and/or controlled release of the drug. The present review focuses on the potential of NPs that can help the targeted and/or controlled delivery of anticancer agents for cancer therapy.

Abstract
Abstract
Objectives
Multidrug resistance (MDR) remains a primary challenge in breast cancer treatment. In the present study, D-alpha-tocopheryl polyethylene glycol 1000 succinate (TPGS)-coated docetaxel-loaded liposomes were developed as a novel drug delivery system to reverse MDR and enhance breast cancer therapy compared with the traditional liposomes, DSPE-mPEG-coated liposomes (stealth liposomes) and commercial Taxotere®.
Key findings
Liposomes were prepared by thin – film dispersion method. Evaluations were performed using human breast cancer MCF-7 and resistant MCF-7/ADR cells. The reversal multidrug-resistant effect was assessed by P-gp inhibition assay, cytotoxicity, cellular uptake and apoptosis assay.
Results
The TPGS-chol-liposomes were of an appropriate particle size (140.0 ± 6.0 nm), zeta potential (−0.196 ± 0.08 mv), high encapsulation efficiency (99.0 ± 0.9) and favourable in vitro sustained release. The TPGS-coated liposomes significantly improved cytotoxicity and increased the intracellular accumulation of docetaxel in both types of breast cancer cells. The TPGS-coated liposomes were confirmed to induce apoptosis via a synergistic effect between docetaxel and TPGS. It was demonstrated that TPGS enhanced the intracellular accumulation of drug by inhibiting overexpressed P-glycoprotein.
Conclusions
The TPGS-conjugated liposomes showed significant advantages in vitro compared with the PEG-conjugated liposomes. The TPGS-conjugated liposomes could reverse the MDR and enhance breast cancer therapy.

Abstract
In this study, a transferrin (Tf)-conjugated polymeric nanoparticle was developed for the targeted delivery of the chemotherapeutic agent doxorubicin (Dox) in order to overcome multi-drug resistance in cancer treatment. Our objective was to improve Dox delivery for producing significant antitumor efficacy in Dox-resistant (R) breast cancer cell lines with minimum toxicity to healthy cells. The results of our experiments revealed that Dox was successfully loaded inside a transferrin (Tf)-conjugated polymeric nanoparticle composed of poloxamer 407 (F127) and 123 (P123) (Dox/F127&P123-Tf), which produced nanosized particles (~90 nm) with a low polydispersity index (~0.23). The accelerated and controlled release profiles of Dox from the nanoparticles were characterized in acidic and physiological pH and Dox/F127&P123-Tf enhanced Dox cytotoxicity in OVCAR-3, MDA-MB-231, and MDA-MB-231(R) cell lines through induction of cellular apoptosis. Moreover, Dox/F127&P123-Tf inhibited cell migration and altered the cell cycle patterns of different cancer cells. In vivo study in MDA-MB-231(R) tumor-bearing mice demonstrated enhanced delivery of nanoparticles to the tumor site when coated in a targeting moiety. Therefore, Dox/F127&P123-Tf has been tailored, using the principles of nanotherapeutics, to overcome drug-resistant chemotherapy.

Abstract
Folate-targeting self-assembled nanoparticles (NPs) using biocompatible and biodegradable natural polymers chitosan (Cs) and chondroitin sulfate (Chs) were developed to address the major challenge in cancer treatment, the selective delivery of nanoparticles to the target site. In this study, we successfully incorporated a hydrophobic drug, bortezomib (Bor), into folic acid (FA)-conjugated Cs/Chs self-assembled NPs (Bor/Cs/Chs-FA) for colorectal cancer therapy. The particle size and polydispersity index of Bor/Cs/Chs-FA were ∼196.5 ± 1.2 nm and ∼0.21 ± 0.5, respectively. A pH-dependent release profile was observed, facilitating cancer cell-targeted drug release under an acidic tumor microenvironment. Moreover, in vitro data revealed enhanced cellular uptake and apoptosis in folate receptor-expressing colorectal cancer cells (HCT-116 and HT-29) as compared to that in lung cancer cells (A549), which do not express folate receptors. Furthermore, intravenous administration of Bor/Cs/Chs-FA in a HCT-116 bearing xenograft mouse model showed that the NPs were a safe and effective drug delivery system. The results suggest that folate-targeted nanoparticle can be effectively applied for efficient chemotherapy of colorectal cancer.

Abstract
Lipid vesicles decorated with polysaccharides have been proposed as vehicles for drug delivery because the polymers confer to the vesicles an enhanced stability, increasing the probability of the drug for reaching the target cell. Here, we first test the affinity of dextran sulfate (DS) for two different vesicle composition, and afterward, we study the effect of DS on the liposome mechanical properties. We found that DS binds to both tested membrane compositions. The interaction of DS with the anionic membranes studied here is mediated by the metal ions present in the aqueous solution (Na+ and Ca2+), being higher in the presence of Ca2+. Binding occurs preferentially in regions of closely packed lipids. Strikingly, DS did not affect the stability against detergent and the membrane rigidity of none of the vesicles. Thus, the proposed stability increase induced by this kind of polymers in drug delivery systems is not related with a modulation of the membrane thermodynamic properties but to other biochemical factors.

Cellular viability and osteogenic differentiation potential of human gingiva-derived stem cells in 2D culture following treatment with anionic, cationic, and neutral liposomes containing doxorubicin. Exp Ther Med 2018; 16:4457-4462.

Abstract
The effects of doxorubicin, particularly doxorubicin liposome, on stem cells have remained to be fully elucidated. The aim of the present study was to evaluate the effects of anionic, cationic and neutral liposomes loaded with doxorubicin on the viability and osteogenic differentiation potential of human gingiva-derived stem cells in two-dimensional culture. Doxorubicin-loaded liposomes were prepared using the traditional thin-lipid-film hydration method. Stem cells were seeded on a culture plate and maintained in osteogenic media. The morphology of the stem cells was observed under an inverted microscope. The number of viable cells was determined using a Cell-Counting Kit-8 assay. The alkaline phosphatase activity was assessed and Alizarin Red S staining was performed to evaluate osteogenic differentiation. A higher concentration of doxorubicin caused noticeable changes in the morphology of the stem cells. Decreases in cellular viability were observed after applying doxorubicin. The application of doxorubicin, particularly at higher concentrations, produced a noticeable decrease in alkaline phosphatase activity and Alizarin Red S staining. The present study indicated that application of doxorubicin with or without liposomes reduced the cellular viability and osteogenic differentiation. Among the different treatments, the doxorubicin-loaded cationic liposomes induced the strongest reduction in the cellular viability and osteogenic differentiation in the stem cell culture.

Abstract
The present study formulated a hydroxyapatite (HA)-coated lipid nanoparticle loaded with zoledronic acid to treat patients with osteoporosis (OP). HA-coated zoledronic acid loaded lipid bilayer nanoparticles (HZL NPs) were prepared using methods of extrusion and precipitation. Nanosized particles were prepared with the aim of increasing gradual and prolonged drug release and inducing toxicity of osteoblasts. Cellular morphology was investigated by scanning electron microscopy, which revealed clear spherical shaped NPs ~200 nm in size that could treat osteopores in the bone. In addition, a typical biphasic release pattern was observed that could be attributed to the presence of drug on the outer surface as well as on the inner core of the NPs. There was sustained release behavior [38.17±2.12% (pH 7.4) and 64.2±3.75% (pH 5) at 48 h] of the drug that maintained the drug reservoir effect at the bone site. Furthermore, HZL NPs increased the cytotoxicity of HFOb 1.19 cells and increased the proportion of cells in the early (18.1±12.4%), late (28.7±3.7%) and necrotic (67.5±1.2%) phases of apoptosis. Most importantly, HZL in the lipid nanoparticle exhibited a strong affinity towards HA, further enhancing its efficacy in the treatment of OP.

Abstract
Drug targeting using functionalized nanoparticles provides a new standard in anticancer therapy. Liposomes, safe and effective drug delivery carriers, can incorporate both hydrophilic and hydrophobic drugs for combination chemotherapy treatment of cancers. The objectives of the current study were to synthesize and test the effectiveness of a nanotechnology-based strategy utilizing folic acid (FA)-conjugated liposomes that incorporate both celastrol (Cs) and irinotecan (Ir) for targeted breast cancer therapy. Our results revealed the successful preparation of Cs and Ir-loaded folate-targeted liposomes (Lipo/Cs/Ir-FA) with a small particle size (∼190 nm) and polydispersity index (∼0.10). The formulation exhibited higher drug release profiles for both Ir and Cs at pH 5.0 compared to those at physiological pH, favoring cancer cell-targeted release. Furthermore, in vitro cell studies showed high uptake and enhanced apoptosis in folate receptor-positive breast cancer cells (MCF-7 and MDA-MB-231), but not in folate receptor-negative lung cancer cells (A549). Moreover, an in vivo study in a mouse tumor model using MDA-MB-231 xenografts supported effective drug delivery behavior of the folate-conjugated liposomes by selective targeting of tumor tissue and minimizing systemic adverse effects. Therefore, our formulation could provide an effective therapy for targeted cancer treatment.

Abstract
In this study, we developed pH and redox-responsive crosslinked polypeptide-based combination micelles for enhanced chemotherapeutic efficacy and minimized side effects. The stability and drug release properties of the polypeptide micelles were efficiency balanced by the corona-crosslinking of the triblock copolymer, poly(ethylene glycol)-b-poly(aspartic acid)-b-poly(tyrosine) (PEG-b-pAsp-b-pTyr) with coordinated redox and pH dual-sensitivity by introducing disulfide crosslinkages. Because of the crosslinking of the middle shell of the triblock polypeptide micelles, their robust structure was maintained in strong destabilization conditions and exhibited excellent stability. GSH concentrations were significantly higher in tumor tissue than in normal tissue, which formed the basis for our design. Drug release was elevated under redox and low acidic conditions. Furthermore, crosslinked micelles showed a superior anticancer effect compared to that of non-crosslinked micelles. Incorporation of docetaxel (DTX) and lonidamine (LND) in crosslinked polypeptide micelles increased the intracellular reactive oxygen species (ROS) level and oxidative stress and caused damage to intracellular components that resulted in greater apoptosis of cancer cells than when DTX or LND was used alone. The combination of DTX and LND in crosslinked micelles exhibited efficacious inhibition of tumor growth with an excellent safety profile compared to that reported for drug cocktail combinations and non-crosslinked micelles. Overall, redox/pH-responsive polypeptide micelles could be an interesting platform for efficient chemotherapy. STATEMENT OF SIGNIFICANCE We have synthesized a biodegradable polypeptide block copolymer to construct a facile pH and redox-responsive polymeric micelle asan advanced therapeutic system for cancer therapy. We have designed a corona-crosslinked triblock copolymer (poly (ethylene glycol)-b-poly(aspartic acid)-b-poly(tyrosine) (PEG-b-pAsp-b-pTyr)) micelles co-loaded with docetaxel and lonidamine (cl-M/DL). The corona of triblock polymer was crosslinked to maintain its structural integrity in the physiological environment. The mitochondrial targeting LND is expected to generate ROS, oxidative stress and thereby synergize the chemotherapeutic efficacy of DTX in killing cancer cells. Consistently, cl-M/DL exhibited excellent antitumor efficacy in xenograft tumor model with remarkable tumor regression. Overall, we demonstrated the construction of bioreducible nanosystem for the effective synergistic delivery of DTX/LND in tumor tissues towards cancer treatment.
