Upgrading the Transdermal Biomedical Capabilities of Thyme Essential Oil Nanoemulsions Using Amphiphilic Oligochitosan Vehicles.

ABSTRACT: (1) Background: Thymus vulgaris L. (thyme) essential oil (TEO) has gained much attention because of its long history of medicinal usage. However, the lack of precise chemical profiling of the TEO and methods to optimize the bioactivity and delivery of its constituents has hampered its research on quality control and biological function; (2) Methods: The current study aimed to analyze the TEO's chemical composition using the GC-MS method and identify its key components. Another objective of this work is to study the impact of the protective layer of amphiphilic oligochitosan (AOC) on the physicochemical stability and transdermal potentials of TEO multilayer nanoemulsions formulated by the incorporation of TEO, Tween80, lecithin (Lec), and AOC; (3) Results: The AOC protective layer significantly improved the stability of TEO-based NEs as revealed by the constancy of their physicochemical properties (particle size and zeta potential) during storage for a week. Excessive fine-tuning of thyme extract NEs and the AOC protective layer's persistent positive charge have been contributed to the thyme extract's improved anti-inflammatory, transdermal, and anti-melanoma potentials; (4) Conclusions: the AOC-coated NEs could offer novel multifunctional nanoplatforms for effective transdermal delivery of lipophilic bioactive materials.

Project description:In order to mitigate the risk of antibiotic resistance in poultry, scientists nowadays consider plant secondary metabolites to be a major organic antibacterial substitute. This study aimed to characterize and investigate the in silico, in vitro, and in vivo antibacterial effects of peppermint essential oil (PEO) in the form of a nanoemulsion (NE), termed PEONE. Menthol as a major compound of PEO has been identified by gas chromatography and mass spectroscopy (GCMS) analysis as 32.3 %, while lower droplet size, polydispersity Index (PDI), and optimum zeta potential values depicted the stability of PEONE have been observed and validated by transmission electron microscopy (TEM) micrograph image. In silico antibacterial activity was studied by molecular docking of menthol and enrofloxacin with Topoisomerase IV protein (PDB: 1s16;) of Escherichia coli K12 MG1655 and this effect was validated by in vitro and in vivo analysis. In vitro analysis, sustained release of PEONE has been observed against Escherichia coli and Staphylococcus aureus. In this study for in vivo experiments (n = 90) day-old broiler chicks were distributed into 6 dietary treatments with 5 replicates of 3 birds per replication. Dietary treatments included 1) Negative control (basal diet), 2) Positive control (basal diet + 200 µl enrofloxacin), 3) 25 µl PEONE + basal diet, 4) 50 µl PEONE + basal diet, 5) 75 µl PEONE + basal diet, and 6) 100 µl PEONE + basal diet. Analyzed data by different statistical tools confirmed that PEONE significantly affected body weight gain (BWG) with an improved feed conversion ratio (FCR) compared to the control group. A significant increase in cecal Lactobacillus count and a decrease in total coliform was observed. Positive effects on physiological parameters, visceral organs, and meat quality characteristics have been observed. In conclusion, our experiments suggest that PEONE can be used in the broiler industry as a substitute for antibiotics to minimize bacterial resistance.
