Abd-Elghany AE, El-Garhy O, Fatease AA, Alamri AH, Abdelkader H. Enhancing Oral Bioavailability of Simvastatin Using Uncoated and Polymer-Coated Solid Lipid Nanoparticles. Pharmaceutics 2024; 16:763. [PMID: 38931885 PMCID: PMC11206705 DOI: 10.3390/pharmaceutics16060763] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/22/2024] [Revised: 06/01/2024] [Accepted: 06/03/2024] [Indexed: 06/28/2024] Open
Abstract
Simvastatin (SVA) is a well-prescribed drug for treating cardiovascular and hypercholesterolemia. Due to the extensive hepatic first-pass metabolism and poor solubility, its oral bioavailability is 5%. Solid lipid nanoparticles (SLNs) and hydrogel-coated SLNs were investigated to overcome the limited bioavailability of SVA. Four different lipids used alone or in combination with two stabilizers were employed to generate 13 SLNs. Two concentrations of chitosan (CS) and alginate (AL) were coating materials. SLNs were studied for particle size, zeta potential, in vitro release, rheology, and bioavailability. The viscosities of both the bare and coated SLNs exhibited shear-thinning behavior. The viscosity of F11 (Chitosan 1%) at 20 and 40 rpm were 424 and 168 cp, respectively. F11 had a particle size of 260.1 ± 3.72 nm with a higher release; the particle size of F11-CS at 1% was 524.3 ± 80.31 nm. In vivo studies illustrated that F11 had the highest plasma concentration when compared with the SVA suspension and coated chitosan (F11 (Chitosan 1%)). Greater bioavailability is measured as (AUC0→24), as compared to uncoated ones. The AUC for F11, F11-CS 1%, and the SVA suspension were 1880.4, 3562.18, and 272 ng·h/mL, respectively. Both bare and coated SLNs exhibited a significantly higher relative bioavailability when compared to that from the control SVA.

Investigation of Levan-Derived Nanoparticles of Dolutegravir: A Promising Approach for the Delivery of Anti-HIV Drug as Milk Admixture. J Pharm Sci 2024:S0022-3549(24)00191-6. [PMID: 38768757 DOI: 10.1016/j.xphs.2024.05.019] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/09/2023] [Revised: 05/15/2024] [Accepted: 05/15/2024] [Indexed: 05/22/2024]
Abstract
Nanoparticles composed of Levan and Dolutegravir (DTG) have been successfully synthesized using a spray drying procedure specifically designed for milk/food admixture applications. Levan, obtained from the microorganism Bacillus subtilis, was thoroughly characterized using MALDI-TOF and solid-state NMR technique to confirm its properties. In the present study, this isolated Levan was utilized as a carrier for drug delivery applications. The optimized spray-dried nanoparticles exhibited a smooth surface morphology with particle sizes ranging from 195 to 329 nm. In the in-vitro drug release experiments conducted in water media, the spray-dried nanoparticles showed 100 % release, whereas the unprocessed drug exhibited only 50 % release at the end of 24 h. Notably, the drug release in milk was comparable to that in plain media, indicating the compatibility. The improved dissolution rate observed for the nanoparticles could be attributed to the solid-state conversion (confirmed by XRD analysis) of DTG from its crystalline to amorphous state. The stability of the drug was verified using Fourier Transform Infra-Red Spectroscopy and Thermogravimetry-Differential Scanning Calorimetry analysis. To evaluate the in-vitro cellular toxicity, 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-2H-tetrazolium bromide (MTT) assay was conducted, which revealed the CC50 value of 88.88 ± 5.10 µg/mL for unprocessed DTG and 101.08 ± 37.37 µg/mL for DTG nanoparticles. These results indicated that the toxicity of the nanoparticles was comparable to the unprocessed drug. Furthermore, the anti-HIV activity of the nanoparticles in human cell lines was found to be similar to that of the pure drug, emphasizing the therapeutic efficacy of DTG in combating HIV.

Pharmaceuticals (Basel) 2023; 16:ph16030380. [PMID: 36986480 PMCID: PMC10056947 DOI: 10.3390/ph16030380] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/03/2023] [Revised: 02/22/2023] [Accepted: 02/26/2023] [Indexed: 03/06/2023] Open
Abstract
A pharmaceutical formulation with favorable pharmacokinetic parameters is more likely to be efficacious and safe to overcome the failures of the drug resulting from lack of efficacy, poor bioavailability, and toxicity. In this view, we aimed to evaluate the pharmacokinetic functionalities and safety margin of an optimized CS-SS nanoformulation (F40) by in vitro/in vivo methods. The everted sac technique was used to evaluate the improved absorption of a simvastatin formulation. In vitro protein binding in bovine serum and mice plasma was performed. The formulation’s liver and intestinal CYP3A4 activity and metabolic pathways were investigated by the qRT-PCR technique. The excretion of cholesterol and bile acids was measured to demonstrate the formulation’s cholesterol depletion effect. Safety margins were determined by histopathology as well as fiber typing studies. In vitro protein binding results revealed the existence of a high percentage of free drugs (22.31 ± 3.1%, 18.20 ± 1.9%, and 16.9 ± 2.2%, respectively) compared to the standard formulation. The controlled metabolism in the liver was demonstrated from CYP3A4 activity. The formulation showed enhanced PK parameters in rabbits such as a lower Cmax, clearance, and a higher Tmax, AUC, Vd, and t1/2. qRT-PCR screening further proved the different metabolic pathways followed by simvastatin (SREBP-2) and chitosan (PPAR-γ pathway) in the formulation. The results from qRT-PCR and histopathology confirmed the toxicity level. Hence, this pharmacokinetic profile of the nanoformulation proved it has a unique synergistic hypolipidemic modality.

Abstract
Hyperlipidemia is the primary cause of heart disorders and has been manifested as the condition with remarkable higher levels of very-low-density lipoproteins, low-density lipoproteins, intermediate-density lipoprotein, triglycerides, and cholesterol in blood circulation. Genetic causes or systemic metabolic illnesses like diabetes mellitus, increased alcohol consumption, hypothyroidism, and primary biliary cirrhosis are several reasons behind development of hyperlipidemia. Higher levels of lipids and lipoproteins in plasma are responsible for various health disorders in human body like occlusion of blood vessels, acute pancreatitis, and reduced artery lumen elasticity. Both primary and secondary prophylaxis of heart disease can be achieved through combination of pharmacologic therapy with therapeutic lifestyle adjustments. Statins which belongs to HMG-CoA reductase inhibitors are preferred for primary prevention of hyperlipidemia particularly for individuals at higher risk of development of heart disease. This review discusses the recent advancements and outcomes of nanoparticle drug carriers for statins in the therapy of hyperlipidemia.

Abstract
Cardiovascular and related diseases (CVRDs) are among the most prevalent chronic diseases in the 21st century, with a high mortality rate. This review summarizes the various nanomedicines for diagnostic and therapeutic applications in CVRDs, including nanomedicine for angina pectoris, myocarditis, myocardial infarction, pericardial disorder, thrombosis, atherosclerosis, hyperlipidemia, hypertension, pulmonary arterial hypertension and stroke. Theranostic nanomedicines can prolong systemic circulation, escape from the host defense system, and deliver theranostic agents to the targeted site for imaging and therapy at a cellular and molecular level. Presently, discrete non-invasive and non-surgical theranostic methodologies are such an advancement modality capable of targeted diagnosis and therapy and have better efficacy with fewer side effects than conventional medicine. Additionally, we have presented the recent updates on nanomedicine in clinical trials, targeted nanomedicine and its translational challenges for CVRDs. Theranostic nanomedicine acts as a bridge towards CVRDs amelioration and its management.

Abstract
Stimuli-responsive nanoparticles are regarded as an ideal candidate for anticancer drug targeting. We synthesized glutathione (GSH) and magnetic-sensitive nanocomposites for a dual-targeting strategy. To achieve this goal, methoxy poly (ethylene glycol) (MePEG) was grafted to water-soluble chitosan (abbreviated as ChitoPEG). Then doxorubicin (DOX) was conjugated to the backbone of chitosan via disulfide linkage. Iron oxide (IO) magnetic nanoparticles were also conjugated to the backbone of chitosan to provide magnetic sensitivity. In morphological observation, images from a transmission electron microscope (TEM) showed that IO nanoparticles were embedded in the ChitoPEG/DOX/IO nanocomposites. In a drug release study, GSH addition accelerated DOX release rate from nanocomposites, indicating that nanocomposites have redox-responsiveness. Furthermore, external magnetic stimulus concentrated nanocomposites in the magnetic field and then provided efficient internalization of nanocomposites into cancer cells in cell culture experiments. In an animal study with CT26 cell-bearing mice, nanocomposites showed superior magnetic sensitivity and then preferentially targeted tumor tissues in the field of external magnetic stimulus. Nanocomposites composed of ChitoPEG/DOX/IO nanoparticle conjugates have excellent anticancer drug targeting properties.

Abstract
Polysaccharide materials are widely applied in different applications including food, food packaging, drug delivery, tissue engineering, wound dressing, wastewater treatment, and bioremediation sectors. They were used in these domains due to their efficient, cost-effective, non-toxicity, biocompatibility, and biodegradability. As is known, polysaccharides can be synthesized by different simple, facile, and effective methods. Of these polysaccharides are cellulose, Arabic gum, sodium alginate, chitosan, chitin, curdlan, dextran, pectin, xanthan, pullulan, and so on. In this current article review, we focused on discussing the synthesis and potential applications of microbial polysaccharides. The biosynthesis of polysaccharides from microbial sources has been considered. Moreover, the utilization of molecular biology tools to modify the structure of polysaccharides has been covered. Such polysaccharides provide potential characteristics to transfer toxic compounds and decrease their resilience to the soil. Genetically modified microorganisms not only improve yield of polysaccharides, but also allow economically efficient production. With the rapid advancement of science and medicine, biosynthesis of polysaccharides research has become increasingly important. Synthetic biology approaches can play a critical role in developing polysaccharides in simple and facile ways. In addition, potential applications of microbial polysaccharides in different fields with a particular focus on food applications have been assessed.

Abstract
The development of biomaterials based on the combination of biopolymers with bioactive compounds to develop delivery systems capable of modulating dentin regeneration mediated by resident cells is the goal of current biology-based strategies for regenerative dentistry. In this article, the bioactive potential of a simvastatin (SV)-releasing chitosan-calcium-hydroxide (CH-Ca) scaffold was assessed. After the incorporation of SV into CH-Ca, characterization of the scaffold was performed. Dental pulp cells (DPCs) were seeded onto scaffolds for the assessment of cytocompatibility, and odontoblastic differentiation was evaluated in a microenvironment surrounded by dentin. Thereafter, the cell-free scaffold was adapted to dentin discs positioned in artificial pulp chambers in direct contact with a 3-dimensional (3D) culture of DPCs, and the system was sealed to simulate internal pressure at 20 cm/H2O. In vivo experiments with cell-free scaffolds were performed in rats' calvaria defects. Fourier-transform infrared spectroscopy spectra proved incorporation of Ca and SV into the scaffold structure. Ca and SV were released upon immersion in a neutral environment. Viable DPCs were able to spread and proliferate on the scaffold over 14 d. Odontoblastic differentiation occurred in the DPC/scaffold constructs in contact with dentin, in which SV supplementation promoted odontoblastic marker overexpression and enhanced mineralized matrix deposition. The chemoattractant potential of the CH-Ca scaffold was improved by SV, with numerous viable and dentin sialoprotein-positive cells from the 3D culture being observed on its surface. Cells at 3D culture featured increased gene expression of odontoblastic markers in contact with the SV-enriched CH-Ca scaffold. CH-Ca-SV led to intense mineralization in vivo, presenting mineralization foci inside its structure. In conclusion, the CH-Ca-SV scaffold induces differentiation of DPCs into a highly mineralizing phenotype in the presence of dentin, creating a microenvironment capable of attracting pulp cells to its surface and inducing the overexpression of odontoblastic markers in a cell-homing strategy.

Chitosan from Crabs (Scylla serrata) Represses Hyperlipidemia-Induced Hepato-Renal Dysfunctions in Rats: Modulation of CD43 and p53 Expression. PATHOPHYSIOLOGY 2021; 28:224-237. [PMID: 35366259 PMCID: PMC8830478 DOI: 10.3390/pathophysiology28020015] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/03/2021] [Revised: 05/10/2021] [Accepted: 05/11/2021] [Indexed: 11/29/2022] Open
Abstract
Hepato-renal dysfunctions associated with hyperlipidemia necessitates a continuous search for natural remedies. This study thus evaluated the effect of dietary chitosan on diet-induced hyperlipidemia in rats. A total of 30 male Wistar rats (90 ± 10) g were randomly allotted into six (6) groups (n = 5): Normal diet, High-fat diet (HFD), and Normal diet + 5% chitosan. The three other groups received HFD, supplemented with 1%, 3%, and 5% of chitosan. The feeding lasted for 6 weeks, after which the rats were sacrificed. The liver and kidneys were harvested for analyses. Hepatic alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP) activity, and renal biomarkers (ALT, AST, urea, and creatinine) were assayed spectrophotometrically. Additionally, expression of hepatic and renal CD43 and p53 was estimated immunohistochemically. The HFD group had elevated bodyweight compared to normal which was reversed in the chitosan-supplemented groups. Hyperlipidemia caused a significant (p < 0.05) decrease in the hepatic (AST, ALT, and ALP) and renal (AST and ALT) activities, while renal urea and creatinine increased. Furthermore, the HFD group showed an elevated level of hepatic and renal CD43 while p53 expression decreased. However, groups supplemented with chitosan showed improved hepatic and renal biomarkers, as well as corrected the aberrations in the expressions of p53 and CD43. Conclusively, dietary chitosan inclusion in the diet (between 3% and 5%) could effectively improve kidney and liver functionality via abatement of inflammatory responses.

Abstract
Herein, a pH and redox dual-responsive drug delivery system (CDs-Pt(iv)-PEG) was developed based on fluorescence carbon dots (CDs). In this system, cisplatin(iv) prodrug (Pt(iv)) was selected as a model drug to reduce toxic side effects. The aldehyde-functionalized monomethoxy polyethylene glycol (mPEG-CHO) was conjugated to CDs-Pt(iv) to form pH sensitive benzoic imine bond. Owing to the slightly acidic tumor extracellular microenvironment (pH 6.8), the benzoic imine bond was then hydrolyzed, leading to charge reversal and decrease in the hydration radius of the drug-carrying, which facilitated in vivo circulation and tumor targeting. Notably, the cytotoxicity of the drug delivery system on cancer cells was comparable to that of cisplatin, while the side effects on normal cells were significantly reduced. In addition, the system realized recognition of cancer cells by the high-contrast fluorescent imaging. In conclusion, the CDs-Pt(iv)-PEG system provided a promising potential for effective delivery of anticancer drugs and cancer cells screening.

Abstract
One of the most promising pharmaceutical research areas is developing advanced delivery systems for controlled and sustained drug release. The drug delivery system (DDS) can be designed to strengthen the pharmacological and therapeutic characteristics of different medicines. Natural polymers have resolved numerous commencing hurdles, which hindered the clinical implementation of traditional DDS. The naturally derived polymers furnish various advantages such as biodegradability, biocompatibility, inexpensiveness, easy availability, and biologically identifiable moieties, which endorse cellular activity in contrast to synthetic polymers. Among them, chitosan has recently been in the spotlight for devising safe and efficient DDSs due to its superior properties such as minimal toxicity, bio-adhesion, stability, biodegradability, and biocompatibility. The primary amino group in chitosan shows exceptional qualities such as the rate of drug release, anti-microbial properties, the ability to cross-link with various polymers, and macrophage activation. This review intends to provide a glimpse into different practical utilization of chitosan as a drug carrier. The first segment of the review will give cognizance into the source of extraction and chitosan's remarkable properties. Further, we have endeavored to provide recent literature pertaining to chitosan applications in various drug delivery systems via different administration routes along with current patented chitosan formulations.

Abstract
Recently, drug-eluting nanofibrous scaffolds have attracted a great attention to enhance the cell differentiation through biomimicking the extracellular matrix (ECM) in regenerative medicine. In this study, electrospun nanocomposite polycaprolactone (PCL)-based scaffolds containing synthesized graphene oxide (GO) nanosheets and osteogenic drugs, i.e. dexamethasone and simvastatin were fabricated. The physicochemical and surface properties of the scaffolds were investigated through FTIR, wettability, pH, and drug release studies. The cell viability, differentiation, and biomineralization were studied on mesenchymal stem cells (MSCs) by Alamar Blue, alkaline phosphatase (ALP) activity, and Alizarin Red-S staining, respectively. Uniformly distributed GO (thickness < 1 nm) in PCL nanofibers was observed by electron microscopy. It was revealed that the addition of GO and the drugs improved the hydrophilicity, cell viability, and osteogenic differentiation, in addition to pH changes, in comparison with PCL scaffolds. Despite the notable reduction in the cell viability, significant differentiation was revealed by ALP assay on PCL/GO-Dex scaffolds. Noteworthy, a twofold increase in the osteogenic differentiation was observed in comparison with the cells cultured in osteogenic differentiation medium, while a significant biomineralization was observed. The results of this study indicate the synergistic effect of GO and dexamethasone on improving osteogenic differentiation of drug-eluting nanocomposite scaffolds in bone tissue engineering applications.

Abstract
In this paper, as an active ingredient, puerarin chitosan nanoparticles (Pur-CS/TPP-NPs) are prepared by an ionic gelation method. The chitosan (CS) concentration, pH of the CS solution, sodium tripolyphosphate (TPP) concentration, stirring speed, stirring time, ultrasonic power, and dosage are used as single factors for investigation, and the encapsulation efficiency, drug loading capacity, particle size, and polydispersity index (PDI) are used as indicators for investigation. The optimal prescription is determined using the Box–Behnken effect surface design method. The characterization of the best formulation, which is determined via an in vitro release assay and liquid chromatography/tandem mass spectrometry (LC-MS/MS) analysis methods, is used here for pharmacokinetic studies. An in situ single-pass intestinal perfusion model is used to investigate drug absorption in the intestine. After characterization, the morphologies of the nanoparticles are intact. It can be seen from the in vitro release experiments that the equation fitted by the nanoparticles is the Higuchi model, the nanoparticle release process is very stable and without sudden release, indicating that the nanoparticles are well-released in vitro. The pharmacokinetic results and the in situ single-pass intestinal perfusion model study show that the bioavailability and absorption of Pur-CS/TPP-NPs were significantly higher than Pur. Thus, all the results show that the prepared nanoparticles can significantly improve the bioavailability of Pur, and we hope to lay the foundation for the development of new products of Pur.

Abstract
The main goal of this study was the preparation and characterization of a chitosan-based system for co-delivery of simvastatin and citicoline to overcome simvastatin unwanted side effects in Alzheimer's disease. This conjugated complex was synthesized in three steps, and 1HNMR, FTIR, and UV-Vis spectroscopy confirmed its success. The simvastatin conjugation rate to chitosan was 1.67 times more than citicoline. X-ray diffraction results showed that the crystalline property of both drugs converted to an amorphous state during the synthesis of the conjugated form. Further, SEM images revealed that the developed nanoparticles have a spherical shape with a size between 100 and 300 nm. Another characterization test was RBC hemolysis, with the lowest value at 6.04% and the highest value at 89.56% and became much lower after preparing nanoparticles using the ionotropic technique. TEM characterized the nanoparticles and showed that the gelation technique stabilized the particles.

Abstract
Objective and methods: This study predicted the nature of chitosan interactions and effects of this interaction on drug release mechanism in simvastatin-loaded chitosan nanoformulation using molecular docking, spectroscopic and thermal analysis. Significance: This work explains in depth the molecular mechanism of simvastatin and chitosan bond formation in nanoformulation. Results: The effective encapsulation and sustain release properties of chitosan were indicated by increase in melting endotherm of simvastatin. Intermolecular hydrogen bond between third hydroxyl group pyranone ring of simvastatin and amino group of chitosan represented the stability of active lactone moiety that was not cleaved during formulation which is prerequisite for biological activity. UV-vis spectroscopic characterization, shift in infrared vibration wavenumber of simvastatin and chitosan, ligand titration, 1HNMR and 13C-NMR analyses confirmed this interaction pattern. The pharmacokinetic evaluation in mouse model revealed the sustain release property of nanoformulation. Conclusion: Thus formation of intermolecular hydrogen bond in nanoformulation contributed to modified physicochemical properties and improved in vivo performance of simvastatin.

Abstract
PURPOSE This study was designed to evaluate the in vitro and in vivo biocompatibility and osteointegration of plasma-sprayed hydroxyapatite (HA)-coated polyethylene terephthalate (PET) ligaments encapsulated with a simvastatin (SV)-chitosan (CS) composite. METHODS This study compared the in vitro and in vivo bone responses to three different PET ligaments: SV/CS/PET-HA, CS/PET-HA and PET-HA. A field emission scanning electron microscope was used to characterize the morphology, and the in vitro SV release profile was analyzed. MC3T3 cells were cocultured with SV/CS/PET-HA, CS/PET-HA and PET-HA to test their biocompatibility using CCK-8 tests. Osteogenic differentiation was investigated by the expression of marker genes using qPCR. Osteointegration was performed by implanting the PET ligaments into the proximal tibia bone tunnels of male Sprague-Dawley rats for 3 weeks and 6 weeks. The bone-implant interface was evaluated by micro-computed tomography (micro-CT) and histological analysis. RESULTS The characteristic nanoporous structures mainly formed on the surface of the plasma-sprayed HA particles in the SV/CS/PET-HA and CS/PET-HA groups. The SV release test showed that the sustained release of simvastatin lasted for 25 days in the SV/CS/PET-HA group. The in vitro studies demonstrated that the SV/CS/PET-HA ligaments induced osteogenic differentiation in the MC3T3 cells, with higher mRNA expression levels of collagen-1, bone morphogenetic protein-2, osteocalcin and alkaline phosphatase than those in the CS/PET-HA and PET-HA ligament groups. The in vivo tests showed that both micro-CT analysis (bone mineral density and bone volume per total volume) and histological analysis (bone implant contact and interface area) revealed significantly higher peri-implant bone formation and less interface area in the SV/CS/PET-HA group than in the other groups. CONCLUSION The SV-CS composite nanoporous structure was associated with the improved biocompatibility and osteogenic differentiation in vitro and enhanced osteointegration process in vivo of plasma-sprayed HA-coated PET ligaments.
