This study investigates the therapeutic potential of essential oil (LOEO) in neurological and pharmaceutical applications. The chemical composition of LOEO was analyzed using gas chromatography-mass spectrometry (GC-MS), revealing major constituents, such as carvacrol, thymol, and γ-gurjunene, known for their antioxidant and antimicrobial properties. LOEO demonstrated significant acetylcholinesterase (AChE)-inhibitory activity, particularly in a nanoformulation that enhances bioavailability and stability. Additionally, the major constituent carvacrol, when tested in isolation, also exhibited AChE-inhibitory activity comparable to that of the nanoformulation. Molecular docking analysis indicated strong binding affinities between LOEO compounds and AChE, supporting its therapeutic potential for neurodegenerative diseases like Alzheimer's. Additionally, in silico pharmacokinetic predictions revealed favorable absorption and blood-brain barrier penetration profiles for key constituents. Despite promising results, this study acknowledges the need for in vivo validation and long-term stability assessments of the nanoformulation. Future research should focus on pharmacodynamic studies and evaluating the oil's effectiveness in animal models. These findings highlight LOEO as a valuable candidate for developing natural therapies for neurodegenerative diseases.
本研究探讨了月桂叶精油(LOEO)在神经学和制药应用中的治疗潜力。采用气相色谱 - 质谱联用仪(GC - MS)分析了LOEO的化学成分,揭示了主要成分,如香芹酚、百里香酚和γ - 古芸烯,这些成分以其抗氧化和抗菌特性而闻名。LOEO表现出显著的乙酰胆碱酯酶(AChE)抑制活性,特别是在一种能提高生物利用度和稳定性的纳米制剂中。此外,主要成分香芹酚单独测试时,也表现出与纳米制剂相当的AChE抑制活性。分子对接分析表明LOEO化合物与AChE之间具有很强的结合亲和力,支持其对阿尔茨海默氏症等神经退行性疾病的治疗潜力。此外,计算机模拟的药代动力学预测显示关键成分具有良好的吸收和血脑屏障穿透特性。尽管取得了有前景的结果,但本研究承认需要对纳米制剂进行体内验证和长期稳定性评估。未来的研究应侧重于药效学研究,并评估该精油在动物模型中的有效性。这些发现突出了LOEO作为开发神经退行性疾病天然疗法的有价值候选物。
