Int J Biol Macromol 2024; 270:132522. [PMID: 38768922 DOI: 10.1016/j.ijbiomac.2024.132522] [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: 02/05/2024] [Revised: 05/05/2024] [Accepted: 05/17/2024] [Indexed: 05/22/2024]
Abstract
The current study goal was to improve mucoadhesive potential and ocular pharmacokinetics of nanoparticles of thiolated xyloglucan (TXGN) containing moxifloxacin (MXF). Thiolation of xyloglucan (XGN) was achieved with esterification with 3-mercaptopropionic acid. TXGN was characterized by NMR and FTIR analysis. The nanoparticles of TXGN were prepared using ionic-gelation method and evaluate the antibacterial properties. TXGN and nanoparticles were determined to possess 0.06 and 0.08 mmol of thiol groups/mg of polymer by Ellman's method. The ex-vivo bioadhesion time of TXGN and nanoparticles was higher than XGN in a comparative assessment of their mucoadhesive properties. The creation of a disulfide link between mucus and TXGN is responsible for the enhanced mucoadhesive properties of TXGN (1-fold) and nanoparticles (2-fold) over XGN. Improved MXF penetration in nanoparticulate formulation (80 %) based on TXGN was demonstrated in an ex-vivo permeation research utilizing rabbit cornea. Dissolution study showed 95 % release of MXF from nanoparticles. SEM images of nanoparticles showed spherical shape and cell viability assay showed nontoxic behavior when tested on RPE cell line. Antibacterial analysis revealed a zone of inhibition of 31.5 ± 0.5 mm for MXF, while NXM3 exhibited an expanded zone of 35.5 ± 0.4 mm (p < 0.001). In conclusion, thiolation of XGN improves its bioadhesion, permeation, ocular-retention and pharmacokinetics of MXF.

Int J Biol Macromol 2024; 257:128597. [PMID: 38056740 DOI: 10.1016/j.ijbiomac.2023.128597] [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: 08/23/2023] [Revised: 11/30/2023] [Accepted: 12/02/2023] [Indexed: 12/08/2023]
Abstract
Breast cancer is the second most prevalent cancer affecting both males and females, comprising nearly 30 % of all cancer cases. While chemotherapeutic agents, such as cisplatin (Cis), have proven successful in cancer treatment, concerns persist regarding their efficacy and the potentially dangerous side effects. Consequently, there is a crucial and ongoing need to develop approaches that minimize side effects associated with chemotherapy. In the present work, various types of nanoparticles (NPs) were synthesized and loaded with Cis. Cis was conjugated with nanocarriers such as zinc oxide (ZnO), ZnO modified with mandelic acid and graphene oxide (GO), chitosan (CS), and CS modified with ZnO and GO to enhance the selectivity of Cis towards cancer cells. Zeta potentials and particles size were assessed using electrophoretic light scattering and dynamic light scattering. NPs were characterized using transmission electron microscopy, Fourier-transform infrared spectroscopy, and X-ray diffraction. The impact of standalone Cis as well as its nanoconjugated form on the behavior of MCF-7 cell line was investigated using WST-1 cell proliferation and apoptosis/necrosis assays. Experimental findings revealed that among the various NPs tested, ZnO, and CS NPs exhibited the highest loading percentage of Cis, surpassing the loading percentages achieved with other NPs. Cytotoxicity assay showed the enhanced effect of Cis when conjugated with ZnO and CS NPs. Flow cytometry-based assays and confocal microscopy confirmed that ZnO/Cis and CS/Cis induced apoptosis. The cisplatin-nanocomplex exhibited a descending order of early apoptosis and late apoptosis in the following order: ZnO, Cis, CS, ZnO-M, CS-GO, ZnO-GO, CS-ZnO, and CS-ZnO, Cis, CS, CS-GO, ZnO-M, ZnO, ZnO-GO, respectively. None of the nanoparticle complexes displayed a significant percentage of necrotic cells, with the highest percentage reaching 4.65 % in the case of CS-GO/Cis.

Abstract
INTRODUCTION Methotrexate shows high efficiency in the treatment of Rheumatoid arthritis, but its adverse effects cannot be tolerated by many patients. Additionally, Methotrexate suffers from rapid clearance from blood. Polymeric nanoparticles were used to solve these problems including chitosan. METHODS Herein, a new nanoparticulate system to deliver Methotrexate (MTX) using chitosan nanoparticles (CS NPs) was developed to be used transdermally. CS NPs were prepared and characterized. The drug release was studied in vitro and ex vivo using rat skin. The drug performance in vivo was investigated on rats. Formulations were applied topically once a day on the paws and knee joints of arthritis rats for 6 weeks. Paw thickness was measured and synovial fluid samples were collected. RESULTS The results showed that CS NPs were monodispersed, and spherical with a size of 279.9 nm and a charge above ± 30mV. Further, 88.02% of MTX was entrapped in the NPs. CS NPs prolonged MTX release and enhanced its permeation (apparent permeability ⁓35.00cm/h) and retention (retention capacity ⁓12.01%) through rats' skin. The transdermal delivery of MTX-CS NPs improves the progress of the disease compared to free MTX, as reflected by the lower arthritic index values, lower proinflammatory cytokines (TNF-α and IL-6), and higher anti-inflammatory cytokine (IL-10) in the synovial fluid. Further, the oxidative stress activities were significantly higher in the group treated with the MTX-CS NPs, as indicated by GSH. Finally, MTX-CS NPs were more effective in reducing lipid peroxidation in synovial fluid. CONCLUSION In conclusion, loading Methotrexate in chitosan nanoparticles controlled its release and enhance its effectiveness against rheumatoid when applied dermally.

Abstract
Modification surface of chitosan nanoparticles using ZnO nanoparticles is important interest in drug delivery because of the beneficial properties. In this study, we proposed a chitosan/ZnO nanocomposite for the targeted delivery of antibacterial peptide (LL37). Synthesized LL37-loaded chitosan/ZnO nanocomposite (CS/ZnO/LL37-NCs) was based on the ionotropic gelation method. The antibacterial activity of the synthesized platform versus Methicillin-resistant Staphylococcus aureus (MRSA) was determined by the microdilution method in 10 mM sodium phosphate buffer. The biofilm formation inhibitory was also evaluated using microtiter plate method. In addition, the ability of CS/ZnO/LL37-NCs on the icaA gene expression level was assessed by the Real-Time PCR. The loading and release investigations confirmed the suitability of CS/ZnO-NCs for LL37 encapsulation. Results showed 6 log10 CFU/ml reduction in MRSA treated with the CS/ZnO/LL37-NPs. Moreover, CS/ZnO/LL37-NCs showed 81 % biofilm formation inhibition than LL37 alone. Also, icaA gene expression decreased 1-fold in the face of CS/ZnO/LL37-NCs. In conclusion, the modification surface of chitosan nanoparticles with ZnO nanoparticles is a suitable chemical platform for the delivery of LL37 that could be used as a promising nanocarrier for enhancing the delivery of antibacterial peptide and improving the antibacterial activity of LL37.

Abstract
The present work aimed to develop nanoparticles of tobramycin (TRM) using thiolated chitosan (TCS) in order to improve the mucoadhesion, antibacterial effect and pharmacokinetics. The nanoparticles were evaluated for their compatibility, thermal stability, particle size, zeta potential, mucoadhesion, drug release, kinetics of TRM release, corneal permeation, toxicity and ocular irritation. The thiolation of chitosan was confirmed by 1H NMR and FTIR, which showed peaks at 6.6 ppm and 1230 cm-1, respectively. The nanoparticles had a diameter of 73 nm, a negative zeta potential (-21 mV) and a polydispersity index of 0.15. The optimized formulation, NT8, exhibited the highest values of mucoadhesion (7.8 ± 0.541h), drug loading (87.45 ± 1.309%), entrapment efficiency (92.34 ± 2.671%), TRM release (>90%) and corneal permeation (85.56%). The release pattern of TRM from the developed formulations was fickian diffusion. TRM-loaded nanoparticles showed good antibacterial activity against Pseudomonas aeruginosa. The optimized formulation NT8 (0.1% TRM) greatly increased the AUC(0-∞) (1.5-fold) while significantly reducing the clearance (5-fold) compared to 0.3% TRM. Pharmacokinetic parameters indicated improved ocular retention and bioavailability of TRM loaded nanoparticles. Our study demonstrated that the TRM-loaded nanoparticles had improved mucoadhesion and pharmacokinetics and a suitable candidate for effective treatment of ocular bacterial infections.

Abstract
Antibiotic resistance is one of the greatest threats to global health and food security today. It becomes increasingly difficult to treat infectious disorders because antibiotics, even the newest ones, are becoming less and less effective. One of the ways taken in the Global Plan of Action announced at the World Health Assembly in May 2015 is to ensure the prevention and treatment of infectious diseases. In order to do so, attempts are made to develop new antimicrobial therapeutics, including biomaterials with antibacterial activity, such as polycationic polymers, polypeptides, and polymeric systems, to provide non-antibiotic therapeutic agents, such as selected biologically active nanoparticles and chemical compounds. Another key issue is preventing food from contamination by developing antibacterial packaging materials, particularly based on degradable polymers and biocomposites. This review, in a cross-sectional way, describes the most significant research activities conducted in recent years in the field of the development of polymeric materials and polymer composites with antibacterial properties. We particularly focus on natural polymers, i.e., polysaccharides and polypeptides, which present a mechanism for combating many highly pathogenic microorganisms. We also attempt to use this knowledge to obtain synthetic polymers with similar antibacterial activity.

Abstract
Abemaciclib (AC) is a novel, orally available drug molecule approved for the treatment of breast cancer. Due to its low bioavailability, its administration frequency is two to three times a day that can decrease patient compliance. Sustained release formulation are needed for prolong the action and to reduce the adverse effects. The aim of current study was to develop sustained release NSs of AC. Nanosponges (NSs) was prepared by emulsion-solvent diffusion method using ethyl-cellulose (EC) and Kolliphor P-188 (KP-188) as sustained-release polymer and surfactant, respectively. Effects of varying surfactant concentration and drug: polymer proportions on the particle size (PS), polydispersity index (PDI), zeta potential (ζP), entrapment efficiency (%EE), and drug loading (%DL) were investigated. The results of AC loaded NSs (ACN1-ACN5) exhibited PS (366.3–842.2 nm), PDI (0.448–0.853), ζP (−8.21 to −19.7 mV), %EE (48.45–79.36%) and %DL (7.69–19.17%), respectively. Moreover, ACN2 showed sustained release of Abemaciclib (77.12 ± 2.54%) in 24 h Higuchi matrix as best fit kinetics model. MTT assay signified ACN2 as potentials cytotoxic nanocarrier against MCF-7 and MDA-MB-231 human breast cancer cells. Further, ACN2 displayed drug release property without variation in the % release after exposing the product at 25 °C, 5 °C, and 45 °C storage conditions for six months. This investigation proved that the developed NSs would be an efficient carrier to sustain the release of AC in order to improve efficacy against breast cancer.
