Optimization of Lipid Nanoparticles by Response Surface Methodology to Improve the Ocular Delivery of Diosmin: Characterization and In-Vitro Anti-Inflammatory Assessment. Pharmaceutics 2022; 14:pharmaceutics14091961. [PMID: 36145708 PMCID: PMC9506089 DOI: 10.3390/pharmaceutics14091961] [Citation(s) in RCA: 8] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/31/2022] [Revised: 09/05/2022] [Accepted: 09/13/2022] [Indexed: 11/28/2022] Open
Abstract
Diosmin is a flavonoid with a great variety of biological activities including antioxidant and anti-inflammatory ones. Its cytoprotective effect in retinal pigment epithelium cells under high glucose conditions makes it a potential support in the treatment of diabetic retinopathy. Despite its benefits, poor solubility in water reduces its potential for therapeutic use, making it the biggest biopharmaceutical challenge. The design of diosmin-loaded nanocarriers for topical ophthalmic application represents a novelty that has not been yet explored. For this purpose, the response surface methodology (RSM) was used to optimize nanostructured lipid carriers (NLCs), compatible for ocular administration, to encapsulate diosmin and improve its physicochemical issues. NLCs were prepared by a simple and scalable technique: a melt emulsification method followed by ultrasonication. The experimental design was composed of four independent variables (solid lipid concentration, liquid lipid concentration, surfactant concentration and type of solid lipid). The effect of the factors was assessed on NLC size and PDI (responses) by analysis of variance (ANOVA). The optimized formulation was selected according to the desirability function (0.993). Diosmin at two different concentrations (80 and 160 µM) was encapsulated into NLCs. Drug-loaded nanocarriers (D-NLCs) were subjected to a physicochemical and technological investigation revealing a mean particle size of 83.58 ± 0.77 nm and 82.21 ± 1.12 nm, respectively for the D-NLC formulation prepared with diosmin at the concentration of 80 µM or 160 µM, and a net negative surface charge (−18.5 ± 0.60 and −18.0 ± 1.18, respectively for the two batches). The formulations were analyzed in terms of pH (6.5), viscosity, and adjusted for osmolarity, making them more compatible with the ocular environment. Subsequently, stability studies were carried out to assess D-NLC behavior under different storage conditions up to 60 days, indicating a good stability of NLC samples at room temperature. In-vitro studies on ARPE-19 cells confirmed the cytocompatibility of NLCs with retinal epithelium. The effect of D-NLCs was also evaluated in-vitro on a model of retinal inflammation, demonstrating the cytoprotective effect of D-NLCs at various concentrations. RSM was found to be a reliable model to optimize NLCs for diosmin encapsulation.

Abstract
Cancer is one of the major health-related issues affecting the population worldwide and subsequently accounts for the second-largest death. Genetic and epigenetic modifications in oncogenes or tumor suppressor genes affect the regulatory systems that lead to the initiation and progression of cancer. Conventional methods, including chemotherapy/radiotherapy/appropriate combinational therapy and surgery, are being widely used for theranostics of cancer patients. Surgery is useful in treating localized tumors, but it is ineffective in treating metastatic tumors, which spread to other organs and result in a high recurrence rate and death. Also, the therapeutic application of free drugs is related to substantial issues such as poor absorption, solubility, bioavailability, high degradation rate, short shelf-life, and low therapeutic index. Therefore, these issues can be sorted out using nano lipid-based carriers (NLBCs) as promising drug delivery carriers. Still, at most, they fail to achieve site targeted drug delivery and detection. This can be achieved by selecting a specific ligand/antibody for its cognate receptor molecule expressed on the surface of cancer cell. In this review, we have mainly discussed the various types of ligands used to decorate NLBCs. A list of the ligands used to design nanocarriers to target malignant cells has been extensively undertaken. The approved ligand decorated lipid-based nanomedicines with their clinical status has been explained in tabulated form to provide a wider scope to the readers regarding ligand coupled NLBCs.

Abstract
Nanotechnology has been a dynamic field for formulation scientists with multidisciplinary research being conducted worldwide. Advancements in development of functional nanosystems have led to evolution of breakthrough technologies. Lipidic nanosystems, in particular, are highly preferred owing to their non-immunogenic safety profiles along with a range of versatile intrinsic properties. Surface modification of lipid nanoparticles by anchoring carbohydrates to these systems is one such attractive drug delivery technology. Carbohydrates confer interesting properties to the nanosystems such as stealth, biostability, bioavailability, reduced toxicity due to decreased immunogenic response, targeting potential as well as ease of commercial availability. The carbohydrate anchored systems can be developed using methods such as adsorption, incorporation (nanoprecipitation or solvent displacement method), crosslinking and grafting. Current review provides a detailed overview of potential lipid based nanoparticulate systems with an emphasis on liposomes, solid lipid nanoparticles, nanostructures lipid carriers and micelles. Review further explores basics of surface modification, methods applied therein, advantages of carbohydrates as surface modifiers, their versatile applications, techniques for characterization of carbohydrate anchored systems and vital regulatory aspects concerned with these specialized systems.

Light-Decomposable Polymeric Micelles with Hypoxia-Enhanced Phototherapeutic Efficacy for Combating Metastatic Breast Cancer. Pharmaceutics 2022; 14:pharmaceutics14020253.

Abstract
Oxygen dependence and anabatic hypoxia are the major factors responsible for the poor outcome of photodynamic therapy (PDT) against cancer. Combining of PDT and hypoxia-activatable bioreductive therapy has achieved remarkably improved antitumor efficacy compared to single PDT modality. However, controllable release and activation of prodrug and safety profiles of nanocarrier are still challenging in the combined PDT/hypoxia-triggered bioreductive therapy. Herein, we developed a near infrared (NIR) light-decomposable nanomicelle, consisting of PEGylated cypate (pCy) and mPEG-polylactic acid (mPEG2k-PLA2k) for controllable delivery of hypoxia-activated bioreductive prodrug (tirapazamine, TPZ) (designated TPZ@pCy), for combating metastatic breast cancer via hypoxia-enhanced phototherapies. TPZ@pCy was prepared by facile nanoprecipitation method, with good colloidal stability, excellent photodynamic and photothermal potency, favorable light-decomposability and subsequent release and activation of TPZ under irradiation. In vitro experiments demonstrated that TPZ@pCy could be quickly internalized by breast cancer cells, leading to remarkable synergistic tumor cell-killing potential. Additionally, metastatic breast tumor-xenografted mice with systematic administration of TPZ@pCy showed notable tumor accumulation, promoting tumor ablation and lung metastasis inhibition with negligible toxicity upon NIR light illumination. Collectively, our study demonstrates that this versatile light-decomposable polymeric micelle with simultaneous delivery of photosensitizer and bioreductive agent could inhibit tumor growth as well as lung metastasis, representing a promising strategy for potent hypoxia-enhanced phototherapies for combating metastatic breast cancer.

Antineoplastics Encapsulated in Nanostructured Lipid Carriers. Molecules 2021; 26:molecules26226929.

Abstract
Ideally, antineoplastic treatment aims to selectively eradicate cancer cells without causing systemic toxicity. A great number of antineoplastic agents (AAs) are available nowadays, with well-defined therapeutic protocols. The poor bioavailability, non-selective action, high systemic toxicity, and lack of effectiveness of most AAs have stimulated the search for novel chemotherapy protocols, including technological approaches that provide drug delivery systems (DDS) for gold standard medicines. Nanostructured lipid carriers (NLC) are DDS that contain a core of solid and lipid liquids stabilised by surfactants. NLC have high upload capacity for lipophilic drugs, such as the majority of AAs. These nanoparticles can be prepared with a diversity of biocompatible (synthetic or natural) lipid blends, administered by different routes and functionalised for targeting purposes. This review focused on the research carried out from 2000 to now, regarding NLC formulations for AAs (antimetabolites, antimitotics, alkylating agents, and antibiotics) encapsulation, with special emphasis on studies carried out in vivo. NLC systems for codelivery of AAs were also considered, as well as those for non-classical drugs and therapies (natural products and photosensitisers). NLC have emerged as powerful DDS to improve the bioavailability, targeting and efficacy of antineoplastics, while decreasing their toxic effect in the treatment of different types of cancer.

Abstract
This study was aimed to determine the physical property and thermodynamic stability of nanostructured lipid carrier suspension incorporating ginsenoside F1 (GF1_NLC), and to evaluate its transport and antioxidant properties. GF1_NLC suspension possessed spherical particles with an average size of 98.9 nm, and the encapsulation efficiency reached approximately 90%. There was a good compatibility between ginsenoside F1 (GF1) and the nanostructured lipid carrier (NLC) formulation, giving no contribution to the changes in the structural organization and crystallization behavior of lipid particles. However, the incorporation of GF1 reduced the thermodynamic stability of the lipid particles. The permeability of GF1_NLC (39.2%) across Caco-2 cell monolayer was higher than that of free GF1 (26.0%); however, no significant differences were observed in the radical scavenging activity (84.1% and 85.5%, respectively). In conclusion, NLC could be a potential candidate for the delivery of GF1 into the living body due to its small particle size, high encapsulation efficiency, and improved permeability. PRACTICAL APPLICATIONS: Poor water solubility in an aqueous solution and low absorption rate of ginsenoside F1 in the intestinal track limit its practical application in food systems. In this study, ginsenoside F1 was encapsulated in nanostructured lipid carrier to enhance its water solubility and absorption rate. The results of the encapsulated ginsenoside F1 showed high encapsulation efficiency of 90% with fine particle size of 98.9 nm that could correspond to the enhancement of water solubility in an aqueous solution and permeability across Caco-2 cell monolayer. The results may encourage the food industry to utilize this encapsulation technique for the enhancement of the functional properties of poorly water-soluble bioactive compounds.

Abstract
Conjugation of D-glucosamine with lipophilic moiety can ease its application in surface modification of liposomes. Interestingly, although D-glucosamine is safe, studies have shed light on "toxic effect" of its conjugates on cancer cells and highlighted its application in targeting glioma. However, understanding the safety of such conjugates for local delivery to the brain is unavailable. Herein, after successful synthesis of D-glucosamine conjugate (GC), the toxicity of functionalized liposome was evaluated both in vitro and in vivo. The study revealed a significant effect on cytotoxicity and apoptosis in vitro as assessed on grade IV-resistant glioma cell lines, SF268, U87MG, using MTT assay and PI staining. Additionally, this effect was not observed on normal human erythrocytes in the hemolysis assay. Furthermore, we demonstrated that GC liposomes were non-toxic to the normal brain tissues of healthy Sprague-Dawley rats. Successful functionalization yielded liposome with uniform particle size, stability, and cellular uptake. With < 10% hemolysis, all the liposomal formulations demonstrated hemato-compatibility but led to high glioma cytotoxicity. The surface density of conjugate played an important role in tumor toxicity (0.5 < 1.0 ≤ 2.0% molar ratio). PI staining revealed that compared to control cell, functionalization led 26-fold increase in induction of apoptosis in glioma cells. Absence of histological and behavioral changes along with the absence of caspase-3 in brain tissue confirmed the suitability of the system for direct infusion in the brain. Thus, this study will aid the future development of clinically useful local chemotherapeutic without "add-in" side effects.

Abstract
To unveil the effect of electrolyte concentration, pH and polymer addition on Tween 80 stabilized nanostructured lipid carriers (NLCs, based on dialkyldimethylammonium bromides DxDAB and Na oleate), an in-depth scattering analysis was performed. Dynamic and static light scattering (DLS/SLS) and small-angle neutron scattering (SANS) techniques along with zeta potential studies were exploited to understand the structural evolution and physical stability of NLCs. In these experiments, we varied the salt concentration, pH, and the admixture of Pluronic F127 in order to elucidate their effect on NLC morphologies. In most cases, two populations of different sizes are present which differ by one order of magnitude. The antileprosy drugs (ALD) Rifampicin and Dapsone were encapsulated in NLCs and the vector properties were assessed for a series of DxDAB (where x = 12, 14, 16 and 18) NLCs. The influence of composition on the entrapment and release behavior of NLCs was investigated: The size of NLCs correlates with the release rate of the incorporated drug. The interaction of drug-loaded NLCs with bovine serum albumin was studied to understand the release of ALD in the plasma.

Abstract
Lipid based nanoparticles (LBNs) with excellent biocompatibility and versatility have received much attention from the drug delivery community recently. A detailed understanding of in vitro and vivo fate of LBNs is important for developing different types of LBNs with improved selectivity and low cytotoxicity. We developed a novel near-infrared (NIR) probe with high fluorescence, designated as DSPE-ir623 (iDSPE). Then, we prepared iDSPE-embeded liposomes (iLPs) with two different hydrodynamic sizes (∼100nm and ∼400nm) to evaluate the effect of particle size on cellular uptake and biodistribution of nanoliposomes in vivo. These iLPs were proved to exhibit good monodispersity, excellent fluorescence and stability. In vitro cell uptake tests demonstrated that iLPs-1 (∼100nm) were taken up more by HT-29 cells than iLPs-2 (∼400nm). Notably, the fluorescence of iLPs can be employed for real-time monitoring of the subcellular locating and its metabolic distribution in vivo. Near-infrared imaging in vivo illustrated that iLPs-1 was mainly accumulated in the tumor tissues, while iLPs-2 was accumulated in liver and spleen. The results indicated that the size of iLPs play an important role in the regulation of intracellular trafficking and biodistribution of liposomes, which also provide a new insight into the development of more effective LBNs. Hence, iDSPE might be a promising tool for the reliable tracing of different types of LBNs.

Abstract
Malignant neoplasms exhibit an elevated rate of glycolysis and a high demand for glucose over normal cells. This characteristic can be exploited for in vivo imaging and tumor targeting examined. In this manuscript, we describe the synthesis of near-infrared (NIR) fluorochrome IR-822-labeled 2-amino-2-deoxy-d-glucose (DG) for optical imaging of tumors in mice. NIR fluorescent dye IR-820 was subsequently conjugated with 3-Mercaptopropionic acid and 2-amino-2-deoxy-d-glucose to form IR-822-DG. The cell experiments and acute toxicity studies demonstrated the low toxicity of IR-822-DG to normal cells/tissues. The dynamic behavior and targeting ability of IR-822-DG in normal mice was investigated with a NIR fluorescence imaging system. The in vitro and in vivo tumor targeting capabilities of IR-822-DG were evaluated in tumor cells and tumor bearing mice, respectively. Results demonstrated that IR-822-DG actively and efficiently accumulated at the site of the tumor. The probe also exhibited good photostability and excellent cell membrane permeability. The study indicates the broad applicability of IR-822-DG for tumors diagnosis, especially in the glucose-related pathologies.

Abstract
Pegylation, as a simple procedure to attach hydrophilic polyethylene glycol (PEG) onto therapeutic molecule or drug carriers has been utilized widely to deliver small molecules, proteins and peptides. It was first reported in 1970s by Dr. Frank Davis of Rutgers University and Dr. Abuchowsky in the studies of PEG modified albumin and catalase. The significance of this method at that time was able to successfully modify the enzyme with better hydrophilicity but also keep the enzymatic activity. The employment of PEG has provided superior stability of drug delivery systems (DDS) and enhanced the circulation time in vivo. Simple conjugation of PEG chains with various molecular weights enables the possibility to regulate the properties of desired DDS and led to important contribution in targeting therapy and diagnosis. Pegylation has been reported to be able to protect peptides by shielding antigenic epitopes from reticuloendothelial (RES) clearance and avoid enzymes being recognized by immune system and avoid early degradation. In addition, utilization of PEG in DDS are reported with enhanced delivery efficiency, prolonged circulation time and improved stability, especially active enzymes and peptides drug delivery. In this paper, we will conclude current studies about Pegylated DDS and their biomedical applications from both in vitro and in vivo studies.

Abstract
During the past decade, pharmaceutical science has seen rapid growth in interest for nanoscale materials. Solid lipid nanoparticles (SLNs) and nanostructured lipid carriers (NLCs) are popular research topics recently introduced as nano-scale drug carriers; they have shown numerous merits in drug delivery. Size is the most important index in a nanocarrier affecting its drug delivery efficiency. The influence of preparation conditions and type of lipidic components on the size of SLN and NLC in comparable states seems to be interesting for researchers who investigate these types of carriers. This review highlights the results of SLN and NLC particle size and size distribution comparisons.

Abstract
AIMS To evaluate the use of glucosamine functionalized multiwalled carbon nanotubes (glyco-MWCNTs) for breast cancer targeting. MATERIALS & METHODS Two types of glucosamine functionalized MWCNTs were developed (covalently linked glucosamine and non-covalently phospholipid-glucosamine coated) and evaluated for their potential to bind and target breast cancer cells in vitro and in vivo. RESULTS & CONCLUSION Binding of glyco-MWCNTs in breast cancer cells is mediated by specific interaction with glucose transporters. Glyco-MWCNTs prepared by non-covalent coating with phospholipid-glucosamine displayed an extended blood circulation time, delayed urinary clearance, low tissue retention and increased breast cancer tumor accumulation in vivo. These studies lay the foundation for development of a cancer diagnostic agent based upon glyco-MWCNTs with the potential for superior accuracy over current radiopharmaceuticals.
