Zhang S, Li C. A curcumin-loaded biopolymeric nanocomposite alleviates dextran sulfate sodium induced ulcerative colitis via suppression of inflammation and oxidative stress. Int J Biol Macromol 2024; 275:133665.

Abstract
Functional drugs nano delivery systems manufactured from natural active products are promising for the field of biomedicines. In this study, an anti-ulcerative colitis (UC) curcumin loaded biopolymeric nanocomposite (CZNH) was fabricated and investigated. CZNH nanocomposite was obtained using the anti-solvent precipitation method, wherein curcumin-loaded zein colloidal particles served as the core, while sodium casein (NaCas) and hyaluronic acid (HA) formed the outermost layer of CZNH nanocomposite. Fourier transform infrared (FT-IR) spectrum and transmission electron microscopy (TEM) findings demonstrated that CZNH nanocomposite was a double-layer spherical micelle (250 nm) resulting from the hydrogen bond interactions and electrostatic adsorptions between zein, NaCas, and HA. Furthermore, CZNH nanocomposite exhibited prominent resuspension and storage stability in aqueous solution, which can be stored at 4 °C for approximately 30 days. In vivo anti-UC studies showed that CZNH nanocomposite could effectively alleviate UC symptoms via mediating inflammatory factors [tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), and IL-6], myeloperoxidase (MPO), and oxidative stress factor [malondialdehyde (MDA), superoxide dismutase (SOD), and glutathione peroxidase (GSH-Px)]. This study suggested that the CZNH nanocomposite showed great promise as an efficient curcumin nanocarrier for UC therapy.

Abstract
In drug delivery, it is common to use porous particles as carrier media, instead of dense particles, due to their high specific surface area and available entrapment volume, which allows a higher amount of drug to be encapsulated and then released. Chitosan microparticles are extensively used in drug delivery, but porous chitosan microparticles are scarcely reported. In this work, the preparation of porous chitosan microparticles using membrane emulsification is addressed, a technology that involves mild operating conditions and less energy consumption than traditional methods (such as ultrasound), and with higher control of the particle size. The dense structure is obtained by a water-in-oil emulsion. The porous structure is obtained by a gas-in-water-in-oil G/W/O double emulsion, where argon bubbles get entrapped in an aqueous chitosan solution that is further emulsified in a paraffin/petroleum ether mixture. Porous chitosan particles were obtained with sizes of 7.7 ± 1.6 μm, which was comparable with dense chitosan particles (6.2 ± 2.3 μm). The pore structure was optimized by varying the argon flow rate, being optimized at 0.24 L h-1. The impact of drug loading by adsorption or encapsulation, and of the drug release behaviour when using porous and dense particles were assessed, using the protein bovine serum albumin (BSA) as a model drug. The results showed that by encapsulating BSA the loading efficiency was above 95 % for both types of particles, with the release being slightly slower for the dense particles. As for the adsorbed BSA, the loading efficiency was significantly higher for porous particles - 70 % - against the 40 % for dense particles. Porous chitosan particles were successfully obtained using the membrane emulsification technology and showed that these carriers are advantageous regarding drug loading and release.

Synergistic anticancer therapy via ferroptosis using modified bovine serum albumin nanoparticles loaded with sorafenib and simvastatin. Int J Biol Macromol 2023; 253:127254. [PMID: 37813219 DOI: 10.1016/j.ijbiomac.2023.127254] [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: 06/06/2023] [Revised: 10/01/2023] [Accepted: 10/03/2023] [Indexed: 10/11/2023]
Abstract
Ferroptosis is a non-apoptotic cell death pathway characterized by the accumulation of lipid-peroxy radicals within the affected cells. Here, we investigate the synergistic capacity of sorafenib (SOR) and simvastatin (SIM) to trigger ferroptosis for cancer therapy. For precise in-vivo delivery, SOR + SIM was ratiometrically loaded in bovine serum albumin nanoparticles (BSA-NPs) modified with 4-carboxy phenylboronic acid (CPBA). The developed CPBA-BSA(SOR + SIM)-NPs revealed size of 175.2 ± 12.8 nm, with PDI of 0.22 ± 0.03 and Z-potential of -29.6 ± 4.8 mV. Significantly, CPBA-BSA(SOR + SIM)-NPs exhibited > 2 and > 5-fold reduction in IC50 values compared to individual SOR and SIM treatments respectively, in all tested cell lines. Moreover, CPBA-BSA(SOR + SIM)-NPs treated cells exhibited decrease in glutathione levels, increase in malonaldehyde levels and depolarization of mitochondrial membrane potential (JC-1 assay). Pharmacokinetic analysis revealed enhanced AUC0-∞ and MRT levels for SOR and SIM when administered as CPBA-BSA(SOR + SIM)-NPs compared to free drugs. Crucially, in in-vivo experiments, CPBA-BSA(SOR + SIM)-NPs led to a significant reduction in tumor volume compared to various control groups. Histological and biomarker analyses underscore their biocompatibility for clinical applications. In conclusion, this study highlights the potential of CPBA-BSA(SOR + SIM)-NPs as a promising strategy for inducing ferroptosis in cancer cells, concurrently improving drug delivery and therapeutic efficacy. This approach opens new avenues in cancer treatment.

Abstract
Aim: To design, optimize and evaluate docetaxel-loaded chitosan nanoparticles with (targeted) and without (nontargeted) cetuximab conjugation for the treatment of non-small-cell lung cancer (NSCLC). Materials & methods: Risk-assessment, optimization, in vitro characterizations, stability assessments, release studies, cell-culture studies were performed along with histopathology, pharmacokinetic and anticancer efficacy studies. Results: The nanoparticles of desired particle size (152.59 ± 3.90 nm to 180.63 ± 5.21 nm) which could sustain drug release for up to 70 h, were obtained. The cell-culture studies demonstrated the superiority of the formulations over Docel™. The pharmacokinetic evaluation showed the excellent systemic bioavailability of prepared NPs. The histopathology screening revealed lesser toxicity of both the nontargeted and targeted formulations. The targeted nanoformulation significantly reduced tumor growth than the nontargeted formulation and Docel. Conclusion: These results demonstrate the therapeutic potential of the prepared nanoformulation. After proper clinical validation, it could be a promising approach for the treatment of NSCLC.

Characteristics, Cryoprotection Evaluation and In Vitro Release of BSA-Loaded Chitosan Nanoparticles. Mar Drugs 2020; 18:md18060315.

Abstract
Chitosan nanoparticles (CS-NPs) are under increasing investigation for the delivery of therapeutic proteins, such as vaccines, interferons, and biologics. A large number of studies have been taken on the characteristics of CS-NPs, and very few of these studies have focused on the microstructure of protein-loaded NPs. In this study, we prepared the CS-NPs by an ionic gelation method, and bovine serum albumin (BSA) was used as a model protein. Dynamic high pressure microfluidization (DHPM) was utilized to post-treat the nanoparticles so as to improve the uniformity, repeatability and controllability. The BSA-loaded NPs were then characterized for particle size, Zeta potential, morphology, encapsulation efficiency (EE), loading capacity (LC), and subsequent release kinetics. To improve the long-term stability of NPs, trehalose, glucose, sucrose, and mannitol were selected respectively to investigate the performance as a cryoprotectant. Furthermore, trehalose was used to obtain re-dispersible lyophilized NPs that can significantly reduce the dosage of cryoprotectants. Multiple spectroscopic techniques were used to characterize BSA-loaded NPs, in order to explain the release process of the NPs in vitro. The experimental results indicated that CS and Tripolyphosphate pentasodium (TPP) spontaneously formed the basic skeleton of the NPs through electrostatic interactions. BSA was incorporated in the basic skeleton, adsorbed on the surface of the NPs (some of which were inlaid on the NPs), without any change in structure and function. The release profiles of the NPs showed high consistency with the multispectral results.

Abstract
Whereas several anticancer peptides are in different stages of clinical development, their administration is limited by the fast elimination from the systemic circulation. Peptide loading on nano-carriers can pave the way for their future application. We have recently indicated that a disulfide loop rather than a Zn-binding loop improves the anti-angiogenic and antitumor activities of the N-terminal fragment of endostatin. In this study, chitosan nanoparticles (CS NPs) are used for the controlled release of the engineered peptide. Loading of the peptide into CS NPs using the ionic gelation method was confirmed by FTIR and resulted in final particle size, poly-dispersity index and surface charge of 186.5 ± 24.0 nm, 0.26 ± 0.02 and 20.1 ± 0.4 mV respectively. The SEM morphological analysis revealed spherical particles with an average size of 80 ± 5 nm. Peptide loading studies revealed that CS NPs are able to adsorb the peptide as ~70%. The release measurements indicated an initial burst release by 49% after 2 hr and complete release after 80 hr. According to in vitro studies, the loaded peptide was much more toxic for endothelial cells than different cancer cell lines. These results underscore the promise of CS NPs as therapeutics nanosystems and open a perspective for improving the clinical applications of peptide drugs.

Abstract
Parkinson's disease (PD) is the most widespread form of dementia where there is an age related degeneration of dopaminergic neurons in the substantia nigra region of the brain. Accumulation of α-synuclein (αS) protein aggregate, mitochondrial dysfunction, oxidative stress, and neuronal cell death are the pathological hallmarks of PD. In this context, amalgamation of curcumin and piperine having profound cognitive properties, and antioxidant activity seems beneficial. However, the blood-brain barrier (BBB) is the major impediment for delivery of neurotherapeutics to the brain. The present study involves formulation of curcumin and piperine coloaded glyceryl monooleate (GMO) nanoparticles coated with various surfactants with a view to enhance the bioavailability of curcumin and penetration of both drugs to the brain tissue crossing the BBB and to enhance the anti-parkinsonism effect of both drugs in a single platform. In vitro results demonstrated augmented inhibition of αS protein into oligomers and fibrils, reduced rotenone induced toxicity, oxidative stress, and apoptosis, and activation of autophagic pathway by dual drug loaded NPs compared to native counterpart. Further, in vivo studies revealed that our formulated dual drug loaded NPs were able to cross BBB, rescued the rotenone induced motor coordination impairment, and restrained dopaminergic neuronal degeneration in a PD mouse model.

Abstract
Silibinin (SIL) is a plant derived flavonoid isolated from the fruits and seeds of the milk thistle (Silybum marianum). Silibinin possesses a wide variety of biological applications including anticancer activities but poor aqueous solubility and poor bioavailability limit its potential and efficacy at the tumor sites. In the present study, silibinin was encapsulated in Eudragit® E (EE) nanoparticles in the presence of stabilizing agent polyvinyl alcohol (PVA) and its anticancer efficacy in oral carcinoma (KB) cells was studied. Silibinin loaded nanoparticles (SILNPs) were prepared by nanoprecipitation technique and characterized in terms of size distribution, morphology, surface charge, encapsulation efficiency and in vitro drug release. MTT assay revealed higher cytotoxic efficacy of SILNPs than free SIL in KB cells. Meanwhile, reactive oxygen species (ROS) determination revealed the significantly higher intracellular ROS levels in SILNPs treated cells compared to free SIL treated cells. Therefore, the differential cytotoxicity between SILNPs and SIL may be mediated by the discrepancy of intracellular ROS levels. Moreover, acridine orange (AO) and ethidium bromide (EB) dual staining and reduced mitochondrial membrane potential (MMP) confirmed the induction of apoptosis with nanoparticle treatment. Further, the extent of DNA damage (evaluated by comet assay) was significantly increased in SILNPs than free SIL in KB cells. Taken together, the present study suggests that silibinin-loaded nanoparticles can be used as an effective drug delivery system to produce a better chemopreventive response for the treatment of cancer.

Abstract
The purpose of this study was to investigate the effect of d-alpha tocopheryl polyethylene glycol 1000 succinate (TPGS) alone or in combination with other emulsifiers in the fabrication of etoposide-loaded PLGA-PEG nanoparticles for in vivo applications. Nanoparticles were prepared by nanoprecipitation or single-emulsion solvent evaporation method using TPGS alone or in combination with other surfactants. These nanoparticles were fully characterized by different techniques. For nanoprecipitation preparations, by adding 0.1% TPGS to polyvinyl alcohol in the aqueous phase, encapsulation efficiency markedly increased (up to 82%); moreover, drug release was readily controlled up to 3 days. Regarding emulsion solvent evaporation method, the highest encapsulation efficiency was obtained for nanoparticles emulsified with polyvinyl alcohol or TPGS; however, the burst release was high. When the combination of TPGS and polyvinyl alcohol was applied a marked increase in encapsulation efficiency (∼ 90%) was observed and the drug release was extended to more than one week. Pharmacokinetic measurements showed that the optimum formulation generated 14.4 times higher AUC and lasted 5.1 times longer when compared to free drug. Overall, using TPGS in combination with polyvinyl alcohol as an emulsifier in preparing etoposide loaded PLGA-PEG nanoparticles markedly increased the encapsulation efficiency, sustained drug release and resulted in nanoparticles with noticeable sustainable in vivo disposition.

Abstract
HP–SPIO NPs (42 nm) were formulated by co-precipitation. Doxorubicin and paclitaxel were loaded into the SPIO NP core. HP–SPIO NPs had sustained release of DOX (87%) and PTX (75%) at pH 6.0. Drug loaded HP–SPIO NPs caused 95 and 84%, and 85 and 77% apoptosis in A2780 and OVCAR-3 cells, respectively. DOX–HP–SPIO NPs and PTX–HP–SPIO NPs caused a sharp decrease in bcl-2 and survivin proteins.

Pullulan-based nanoparticles as carriers for transmucosal protein delivery. Eur J Pharm Sci 2013; 50:102-13.

Abstract
Polymeric nanoparticles have revealed very effective in transmucosal delivery of proteins. Polysaccharides are among the most used materials for the production of these carriers, owing to their structural flexibility and propensity to evidence biocompatibility and biodegradability. In parallel, there is a preference for the use of mild methods for their production, in order to prevent protein degradation, ensure lower costs and easier procedures that enable scaling up. In this work we propose the production of pullulan-based nanoparticles by a mild method of polyelectrolyte complexation. As pullulan is a neutral polysaccharide, sulfated and aminated derivatives of the polymer were synthesized to provide pullulan with a charge. These derivatives were then complexed with chitosan and carrageenan, respectively, to produce the nanocarriers. Positively charged nanoparticles of 180-270 nm were obtained, evidencing ability to associate bovine serum albumin, which was selected as model protein. In PBS pH 7.4, pullulan-based nanoparticles were found to have a burst release of 30% of the protein, which maintained up to 24h. Nanoparticle size and zeta potential were preserved upon freeze-drying in the presence of appropriate cryoprotectants. A factorial design was approached to assess the cytotoxicity of raw materials and nanoparticles by the metabolic test MTT. Nanoparticles demonstrated to not cause overt toxicity in a respiratory cell model (Calu-3). Pullulan has, thus, demonstrated to hold potential for the production of nanoparticles with an application in protein delivery.

Abstract
To optimize the preparation process of chitosan microspheres and study its loading capacity, chitosan microsphere was prepared by crosslinking with glutaraldehyde, and bovine serum albumin (BSA) was absorbed onto chitosan microsphere. Scanning electron microscope (SEM), Fourier transform infrared spectroscopy (FITR), TA instruments and zeta potentiometer analyzer were used to characterize the parameters with respect to size, thermal characters, morphology, and zeta potential of the microspheres. The loading capability and in vitro release tests were carried out. The results showed that chitosan microsphere with particle size less than 10 μm and positively charged (+25.97±0.56 mV) can be obtained under the aldehyde group to amino group ratio at 1:1. A loading capacity of BSA at 28.63±0.15 g/100 g with corresponding loading efficiency at 72.01±1.44% was obtained for chitosan microsphere. In vitro test revealed a burst release followed by sustained-release profile.

Abstract
Superparamagnetic iron oxide nanoparticles are currently used for precise drug delivery and as an image contrast agent. In the present study, the potentiality of curcumin-loaded magnetic nanoparticles (Cur-MNPs) for the treatment of chronic myeloid leukemia (CML) was investigated. For active therapy, transferrin (Tf) ligand was further conjugated to Cur-MNPs, which demonstrated enhanced uptake compared to Cur-MNPs in p210bcr/abl-positive cell line (K562). Cur-MNPs demonstrated greater and sustained anti-proliferative activity in a dose- and time-dependent manner; however, with the advent of a magnetic field the anti-proliferative activity of Cur-MNPs as well as Tf-Cur-MNPs was enhanced due to higher cellular uptake with enhanced cytotoxicity activity. Down-regulation of Bcr-Abl protein activates intrinsic apoptotic pathways for promoting anti-leukemic responses. Our in vitro results advocate potential clinical applications of Cur-MNPs by activating multiple signaling pathways for provoking the anti-leukemic activity.

Abstract
There is much interest in utilizing the intrinsic properties of magnetic nanoparticles (MNPs) for the theranostic approaches in medicine. With an aim to develop a potential therapeutics for glioma treatment, efficacy of aqueous dispersible paclitaxel loaded MNPs (Pac-MNPs) were studied in glioblastoma cell line (U-87). The identified potential receptor, glycoprotein non-metastatic melanoma protein B (GPNMB) overexpressed by glioblastoma cells, was actively targeted using GPNMB conjugated Pac-MNPs in U-87 cells. As blood brain barrier (BBB) is the primary impediment in the treatment of glioblastoma, therefore, an attempt was taken to evaluate the biodistribution and brain uptake of Pac-MNPs in rats. The bioavailability of Pac-MNPs illustrated a prolonged blood circulation in vivo, which demonstrated the presence of significant amounts of drug in rat brain tissues as compared to native paclitaxel. Further, the transmission electron microscopy (TEM) study revealed significant accumulation of the Pac-MNPs in the brain tissues. Being an effective contrast enhancement agent for magnetic resonance imaging (MRI) at tissue levels, the MNPs devoid of any surfactant demonstrated enhanced contrast effect in liver and brain imaging. Hence, the significant prevalence of drugs in the rat brain tissues, in vitro targeting potentiality as well as the augmented contrast effect elicit the non-invasive assessment and theranostic applications of MNPs for brain tumor therapy.

Abstract
The application of poly(hydroxybutyrate-co-hydroxyhexanoate) (PHBHHx) for sustained and controlled delivery of hydrophilic insulin was made possible by preparing insulin phospholipid complex loaded biodegradable PHBHHx nanoparticles (INS-PLC-NPs). The INS-PLC-NPs produced by a solvent evaporation method showed a spherical shape with a mean particle size, zeta potential and entrapment efficiency of 186.2 nm, -38.4 mv and 89.73%, respectively. In vitro studies demonstrated that only 20% of insulin was released within 31 days with a burst release of 5.42% in the first 8 h. The hypoglycaemic effect in STZ induced diabetic rats lasted for more than 3 days after the subcutaneous injection of INS-PLC-NPs, which significantly prolonged the therapeutic effect compared with the administration of insulin solution. The pharmacological bioavailability (PA) of INS-PLC-NPs relative to insulin solution was over 350%, indicating that the bioavailability of insulin was significantly enhanced by INS-PLC-NPs. Therefore, the INS-PLC-NPs system is promising to serve as a long lasting insulin release formulation, by which the patient compliance can be enhanced significantly. This study also showed that phospholipid complex loaded biodegradable nanoparticles (PLC-NPs) have a great potential to be used as a sustained delivery system for hydrophilic proteins to be encapsulated in hydrophobic polymers.

Abstract
To date cancer is considered as one of the most devastating diseases due to its high rate of mortality. Preclinical studies have demonstrated that the Akt/mTOR (mammalian target of rapamycin) pathway is activated in cancers and inhibition of this pathway has great potential in anti-cancer therapy. Rapamycin, one of the most potent anti-cancer drugs, blocks Akt/mTOR function and has anti-proliferative activity in several cancers. To circumvent problems associated with rapamycin due to its poor water solubility, poor oral bioavailability, low accessibility to cancer tissues and systemic toxicity, rapamycin-loaded cubic nanoparticles (NP) were formulated with vitamin E d-α-tocopheryl polyethylene glycol 1000 succinate (TPGS) as an emulsifier for oral delivery. Cubic NP were characterised and these particles demonstrated better cytotoxicity and apoptosis compared with native rapamycin under in vitro conditions due to their enhanced cellular uptake. The molecular impact of particulate systems on the Akt/mTOR pathway were elucidated by immunoblotting. Down-regulation of different anti-apoptotic genes of this pathway indicates activation of apoptotic signals leading to MIA PaCa cell death. An in vivo study demonstrated enhanced bioavailability of rapamycin in cubic NP in comparison with native rapamycin in a mouse model with no toxicity and good biocompatibility of void cubic NP at a higher dose of oral administration. Thus, rapamycin-loaded cubic NP can be used as an effective drug delivery system to produce better rapamycin therapeutics for the treatment of cancers.

Abstract
To develop a suitable formulation with high entrapment efficiency, etoposide-loaded poly(lactide-co-glycolide) nanoparticles (NPs) were formulated by single emulsion-solvent evaporation method by changing different formulation parameters such as drug loading, choice of organic solvent and percentage of emulsifier polyvinyl alcohol. The NPs showed higher entrapment efficiency, ~86% (with 15% (w/w) drug loading). The physicochemical parameters revealed smooth topology with size range (240–320 nm), a negative zeta potential (~19 mV) and in vitro sustained-release activity (~60% drug release in 40 days). Greater anti-proliferative activity ~100 times was observed with NPs (IC50 = 0.002 μg/ml) than that of native etoposide (IC50 = 0.2 μg/ml) in retinoblastoma cell line (Y-79). These NPs demonstrated greater (G1/S) blocking and decreased mitochondrial membrane potential as measured by flow cytometry. There was upregulation of apoptotic gene activity in NPs than native etoposide, as revealed through microarray analysis. However, this is the first ever report demonstrating the intricate modulation of genetic network affected by NPs. Collectively, these results suggest that etoposide-loaded NPs could be potentially useful as a novel drug delivery system for retinoblastoma in the future. Nanoparticle-mediated etoposide delivery promotes apoptosis through upregulating several apoptotic inducer genes ![]()

Abstract
Gemcitabine [2', 2'-difluoro-2'-deoxycytidine (dFdC)] is a low molecular weight, deoxycytidine analog inhibiting cellular DNA synthesis. Currently, it is the frontline drug approved by Food and Drug Administration (FDA) for the treatment of pancreatic cancer. However, efforts to use gemcitabine as an anti-cancer agent have been limited by its short circulation time and rapid metabolism that reflects in low tumor uptake and intracellular action. Polymer-drug conjugates, in this regard have spawned an approach to improve the cytotoxicity efficiency and bioavailability of gemcitabine by chemical modification. The present study describes the synthesis of a water soluble formulation of PEGylated gemcitabine characterized by FT IR, (1)H NMR and RP-HPLC chromatography. The PEGylated gemcitabine has a prolonged circulation time in plasma as studied in an animal model. This eventually caused a marked improvement in the cytotoxicity and apoptosis-inducing activity in pancreatic cancer cell lines (MIA PaCa 2 and PANC 1). Hence, these findings demonstrate the PEGylated gemcitabine is a desirable approach for therapy by intravenous administration. Successful clinical application of this approach can significantly contribute to the treatment of pancreatic cancer.

Abstract
The primary inadequacy of chemotherapeutic drugs is their relative non-specificity and potential side effects to the healthy tissues. To overcome this, drug loaded multifunctional magnetic nanoparticles are conceptualized. We report here an aqueous based formulation of glycerol monooleate coated magnetic nanoparticles (GMO-MNPs) devoid of any surfactant capable of carrying high payload hydrophobic anticancer drugs. The biocompatibility was confirmed by tumor necrosis factor alpha assay, confocal microscopy. High entrapment efficiency approximately 95% and sustained release of encapsulated drugs for more than two weeks under in vitro conditions was achieved for different anticancer drugs (paclitaxel, rapamycin, alone or combination). Drug loaded GMO-MNPs did not affect the magnetization properties of the iron oxide core as confirmed by magnetization study. Additionally the MNPs were functionalized with carboxylic groups by coating with DMSA (Dimercaptosuccinic acid) for the supplementary conjugation of amines. For targeted therapy, HER2 antibody was conjugated to GMO-MNPs and showed enhanced uptake in human breast carcinoma cell line (MCF-7). The IC(50) doses revealed potential antiproliferative effect in MCF-7. Therefore, antibody conjugated GMO-MNPs could be used as potential drug carrier for the active therapeutic aspects in cancer therapy.
