Abstract
Poor drug penetration, emerging drug resistance, and systemic toxicity are among the major obstacles challenging the current treatment of cutaneous leishmaniasis. Hence, developing advanced strategies for effective and targeted delivery of antileishmanial agents is crucial. Several drug delivery carriers have been developed till current date for dermal/transdermal delivery, especially those which are fabricated using eco-friendly synthesis approaches, since they protect the environment from the harmful effects of chemical waste disposal. This work describes the preparation of selenium nanoparticles loaded with silymarin via one-pot green reduction technique, for treatment of cutaneous leishmaniasis. The selected silymarin loaded selenium nanoparticles (SSNs4-0.1) displayed good loading efficiency of 58.22 ± 0.56 %, zeta potential of -30.63 ± 0.40 mV, hydrodynamic diameter of 245.77 ± 11.12 nm, and polydispersity index of 0.19 ± 0.01. It exhibited good physical stability, as well as high ex vivo deposition % in the epidermis (46.98 ± 1.51 %) and dermis (35.23 ± 1.72 %), which was further proven using confocal laser microscopy. It also exhibited significant cytocompatibility and noticeable cellular internalization of 90.02 ± 3.81 % in human fibroblasts, as well as high trypanothione reductase inhibitory effect (97.10 ± 0.30 %). Results of this study confirmed the successful green synthesis of silymarin-loaded selenium nanoparticles; delineating them as one of the promising antileishmanial topical delivery systems.

Int J Biol Macromol 2024; 260:129398. [PMID: 38224814 DOI: 10.1016/j.ijbiomac.2024.129398] [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: 08/16/2023] [Revised: 01/08/2024] [Accepted: 01/09/2024] [Indexed: 01/17/2024]
Abstract
Lignocellulose nanofibers (LCNF) obtained from agricultural waste are potential candidates for enhancing composite materials because of their excellent mechanical properties, abundant groups and high biocompatibility. However, the application of LCNF has received limited attention to date from researchers in the healthcare field. Herein, based on the bifunctional group (carboxyl and aldehyde groups) modified LCNF (DCLCNF) and chitosan (CS), we developed a multifunctional bio-based hydrogel (CS-DCLCNF). The addition of lignin-containing DCLCNF strengthened the internal crosslinking and the intermolecular interaction of hydrogels, and the presence of lignin and carboxyl groups increased the mechanical strength of the hydrogel and the adsorption of aromatic drugs. Results revealed that the hydrogels exhibited self-healing, injectable, and high swelling rates. The hydrogels had favorable mechanical strength (G'max of ~16.60 kPa), and the maximum compressive stress was 24 kPa. Moreover, the entire tetracycline hydrochloride (TH) release process was slow and pH-responsive, because of the rich noncovalent and π-π interactions between DCLCNF and TH. The hydrogels also exhibited excellent biocompatibility and antibacterial properties. Notably, the wound healing experiment showed that the hydrogels were beneficial in accelerating wounds healing, which could heal completely in 13 days. Therefore, CS-DCLCNF hydrogels may have promising applications in drug delivery for wound healing.

Formulation of silymarin binary and ternary solid dispersions: Characterization, simulation study and cell viability assessment against lung cancer cell line. Heliyon 2024; 10:e23221. [PMID: 38163135 PMCID: PMC10756988 DOI: 10.1016/j.heliyon.2023.e23221] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/01/2023] [Revised: 11/28/2023] [Accepted: 11/29/2023] [Indexed: 01/03/2024] Open
Abstract
Silymarin (SL) is a water-insoluble flavonoid used in the treatment of different diseases, but its therapeutic activity is limited due to its low solubility. So, in the present study, SL solid dispersions (SDs) were developed using different carriers like Kollidone VA64 (KL), Soluplus (SP), and Poloxamer 188 (PL) by solvent evaporation (SE), microwave irradiation (MI), and freeze-drying (FD) methods. The phase solubility and saturation solubility studies were assessed to estimate the stability constant as well as the carrier effect. The dissolution studies were performed for prepared SL-SDs (binary and ternary) to select the optimum SL-SDs. The selected SL-SDs (F5, F9) were further characterized for infrared spectroscopy (IR), nuclear magnetic resonance (NMR), differential scanning calorimeter (DSC), scanning electron microscope (SEM), and X-ray diffraction (XRD). Finally, the comparative cell viability assay (lung cancer cell line) was performed to evaluate the change in activity after the formulation of SDs. The phase solubility and solubility study results displayed marked enhancements in solubility. The dissolution study findings showed significant enhancement in drug release from ternary solid dispersions (F7-F9) > ternary physical mixture (PM3) > binary solid dispersions (F1-F6) > binary physical mixture (PM1, PM2) in comparison to free SL. A greater release was observed from ternary SDs due to the addition of PL in the formulation, which had a synergistic effect on increasing the solubility. IR and NMR spectra revealed no chemical interaction between SL, KL, and PL. DSC, XRD, and SEM all confirmed the transformation of crystalline SL into amorphous SL. The cell viability assay demonstrated significantly enhanced results from ternary solid dispersion (F9) compared to free SL. Based on the study results, it can be said that SL-SDs are an alternative way to deliver drugs orally that can improve solubility and have anti-cancer activity.

Sucrose acetate isobutyrate (SAIB) and glyceryl monooleate (GMO) hybrid nanoparticles for bioavailability enhancement of rivaroxaban: an optimization study. Pharm Dev Technol 2023; 28:928-938. [PMID: 37870222 DOI: 10.1080/10837450.2023.2274944] [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: 07/26/2023] [Accepted: 10/20/2023] [Indexed: 10/24/2023]
Abstract
This study aims to improve the RXB bioavailability using hybrid nanoparticles. A modified melt dispersion technique created different formulas with varying GMO-SAIB: RXB and GMO: SAIB ratios, with fixed GMO-SAIB: poloxamer 407 ratios. The PS, PDI, ZP, and EE were measured to determine the optimal formula, which was selected using Design-Expert™ software. The optimized formula was lyophilized and tested for PS, PDI, ZP, and EE. The chosen lyophilized formula (L4) was characterized using FTIR, DSC, PXRD, dissolution studies, and pharmacokinetics studies. The study found correlations between variables and identified how GMO-SAIB concentration affects drug encapsulation. The dissolution parameters were calculated, including % Q5 and % DE). The % Q5 values were 68.4 ± 1.7% and 89.7 ± 3.6% for Xarelto and L4 tablets, respectively. The % DE values were 89.7 ± 0.4% and 97.5 ± 2.1% for Xarelto and L4 tablets, respectively. The AUC values were 2117.0 ng.h/mL (±77.3) and 3919.4 ng.h/mL (±134.8) for Xarelto and L4 tablets, respectively. The Cmax values were 241.3 ng/mL (±21.0) and 521.5 ng/mL (±91.5) for Xarelto and L4 tablets, respectively. In conclusion, the study found that using GMO-SAIB as co-formers effectively enhanced the bioavailability of RXB. The authors recommend using the hybrid nanoparticles technique and suggest further research to enhance its effectiveness for drug delivery.
