Abstract
In recent years, the alarming spread of antibiotic resistance has posed a grave global threat to public health, resulting in millions of fatalities worldwide. Multidrug-resistant (MDR) microorganisms have emerged due to the broad spread of resistance and the sharing of resistance genes between various varieties of bacteria. A promising strategy for treating difficult-to-treat bacterial infections is the development of nanomaterial-based therapeutics that could circumvent existing pathways linked to acquire drug resistance. The objectives of this study were to prepare chitosan/pectin-encapsulated Echinacea pallida (E. pallida) extract and evaluate its efficacy against MDR isolates. E. pallida extract was encapsulated into chitosan (CS)/pectin (PN) nanoparticles (NPs) using the gelation technique in the present study. The synthesized NPs were analyzed using scanning electron microscopy (SEM), dynamic light scattering (DLS), transmission electron microscopes (TEM), and Fourier transform infrared (FT-IR) spectroscopy. Antibacterial and antibiofilm activity of the nanoparticles against S. aureus has been assessed and explored. In addition, the toxicity of synthetic NPs against HEK 93 cells was evaluated. The interactions between functional groups were confirmed by FT-IR spectroscopy. The CS/PN NPs were spherical with uniform surfaces, and their dimension ranged from 80 to 110 nm. The PDI of the E. pallida extract was 0.521, and its entrapment efficiency (EE%) was 84.35%. The synthesized CS/PN NPs exhibited antibacterial and antibiofilm activity against bacteria relevant to public health. In addition, the results demonstrated that the extract-containing NPs had no toxic impact on HEK-93 cells. The findings presented here should aid the development of novel plant extracts with enhanced stability and antibacterial activity, thereby reducing the need for antibiotics.

Extract as In Situ Gel Enhances Chronic Wound Healing: In Vitro, In Vivo, and In Silico Studies. Pharmaceuticals (Basel) 2023; 16:957. [PMID: 37513869 PMCID: PMC10383585 DOI: 10.3390/ph16070957] [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: 05/31/2023] [Revised: 06/25/2023] [Accepted: 06/30/2023] [Indexed: 07/30/2023] Open
Abstract
This study shed light for the first time on the in vivo diabetic wound healing potential activity of natural marine soft coral polymeric nanoparticle in situ gel using an excision wound model. A Nephthea sp. methanol-methylene chloride extract loaded with pectin nanoparticles (LPNs) was created. For the preparation of in situ gel, ion-gelation techniques, the entrapment efficiency, the particle size, the polydispersity index, the zeta potential, the in-vitro drug release, and a transmission electron microscope were used and the best formula was selected. Using (UPLC-Q/TOF-MS), 27 secondary metabolites responsible for extract biological activity were identified. Isolation and identification of arachidic acid, oleic acid, nervonic acid, and bis-(2-ethylhexyl)-phthalate (DEHP) of Nephthea sp. was firstly reported here using NMR and mass spectral analyses. Moreover, LPN in situ gel has the best effects on regulating the proinflammatory cytokines (NF-κB, TNF-α, IL-6, and IL-1β) that were detected on days 7 and 15. The results were confirmed with an in vitro enzymatic inhibitory effect of the extract against glycogen synthase kinase (GSK-3) and matrix metalloproteinase-1 (MMP-1), with IC50 values of 0.178 ± 0.009 and 0.258 ± 0.011 µg/mL, respectively. The molecular docking study showed a free binding energy of -9.6 kcal/mol for chabrolosteroid E, with the highest binding affinity for the enzyme (GSK-3), while isogosterone B had -7.8 kcal/mol for the enzyme (MMP-1). A pharmacokinetics study for chabrolohydroxybenzoquinone F and isogosterone B was performed, and it predicted the mode of action of wound healing activity.

Ceftizoxime loaded ZnO/L-cysteine based an advanced nanocarrier drug for growth inhibition of Salmonella typhimurium. Sci Rep 2021; 11:15565. [PMID: 34330977 PMCID: PMC8324911 DOI: 10.1038/s41598-021-95195-0] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/02/2021] [Accepted: 07/21/2021] [Indexed: 11/16/2022] Open
Abstract
l-Cysteine coated zinc oxide (ZnO) nano hollow spheres were prepared as a potent drug delivery agent to eradicate Salmonella enterica serovar Typhimurium (S. typhimurium). The ZnO nano hollow spheres were synthesized by following the environmentally-friendly trisodium citrate assisted method and l-cysteine (L-Cys) conjugate with its surface. ZnO/L-Cys@CFX nanocarrier drug has been fabricated by incorporating ceftizoxime with L-Cys coated ZnO nano hollow spheres and characterized using different techniques such as scanning electron microscope (SEM), attenuated total reflection Fourier transform infrared (ATR-FTIR), and X-ray diffraction (XRD) etc. Furthermore, the drug-loading and encapsulation efficiency at different pH levels was measured using UV–vis spectrometer and optimized. A control and gradual manner of pH-sensitive release profile was found after investigating the release profile of CFX from the carrier drug. The antibacterial activity of ZnO/L-Cys@CFX and CFX were evaluated through the agar disc diffusion method and the broth dilution method, which indicate the antibacterial properties of antibiotics enhance after conjugating. Surprisingly, the ZnO/L-Cys@CFX exhibits a minimum inhibitory concentration (MIC) of 5 µg/ml against S. typhimurium is lower than CFX (20 µg/ml) itself. These results indicate the nanocarrier can reduce the amount of CFX dosed to eradicate S. typhimurium.
