摘要

阿尔茨海默病（AD）仍然是一个重大的全球健康挑战，没有明确的治疗方法。目的研究核桃精油作为一种靶向NMDA受体通路的AD治疗分子的来源。研究设计方法：采用水蒸气蒸馏法提取挥发油，GC-MS分析挥发油化学成分。采用DPPH法测定其抗氧化活性。分子对接比较了化合物与NMDA受体对美金刚的亲和力，并通过药代动力学分析评估药物相似性。并进行了相互作用和分子动力学分析。结果gc - ms共鉴定出34个化合物，主要为石竹烯氧化物（20.6%）和β-丁香酚（10.7%）。DPPH测定的IC50值为855.34 μg/mL。11个化合物对美金刚胺具有优异或相当的亲和力（−7.4 kcal/mol）。Eudesma-4(15)，7-dien-1-β-ol表现出特殊的NMDA受体相互作用，在结合亲和力、相互作用质量和分子动力学稳定性方面优于美金刚，同时满足药物相似标准。结论王参Eudesma-4(15)，7-二烯-1-β-醇通过NMDA受体调节，有望成为阿尔兹海默病的治疗候选药物，值得临床研究以评估其治疗效果和安全性。

Background

Alzheimer's disease (AD) remains a significant global health challenge, with no definitive cure available.

Purpose

This study investigates Juglans regia essential oil as a source of therapeutic molecules for AD, targeting the NMDA receptor pathway.

Study design

& Methods: The essential oil was extracted by hydrodistillation, and the GC-MS analyzed the chemical composition. Antioxidant activity was evaluated using DPPH assay. Molecular docking compared compound affinities to the NMDA receptor against Memantine, with pharmacokinetic analysis evaluating drug-likeness. Interaction and molecular dynamic analysis were also performed.

Results

GC-MS identified 34 compounds, predominantly caryophyllene oxide (20.6 %) and β-Eudesmol (10.7 %). The DPPH assay resulted in an IC₅₀ value of 855.34 μg/mL. Eleven compounds showed superior/equivalent affinities (−7.4 kcal/mol) to Memantine. Eudesma-4(15),7-dien-1-β-ol demonstrated exceptional NMDA receptor interaction, outperforming Memantine in binding affinity, interaction quality, and stability in molecular dynamics while meeting drug-likeness criteria.

Conclusion

These findings suggest that Eudesma-4(15),7-dien-1-β-ol from J. regia shows promise as an AD therapeutic candidate via NMDA receptor modulation, warranting clinical investigation to assess its therapeutic efficacy and safety.
