摘要:



文题释义:
飞龙掌血:芸香科植物飞龙掌血Toddalia asiatica (L.) Lam.的干燥根或茎皮。据《中华本草 苗药卷》记载:飞龙掌血味苦、性冷,入热经,具有散瘀止血、祛风除湿、消肿解毒以及止痛,接骨,解表等功效。
分子动力学模拟:基于牛顿力学原理模拟原子和分子物理运动轨迹和状态的方法,对于较为复杂的生物分子体系,通常通过对相互作用粒子的牛顿运动方程进行数值解析来确定体系内粒子的轨迹,而粒子间的作用力和势能采用分子力学力场来确定。

背景:飞龙掌血在类风湿性关节炎中的治疗潜力日益受到重视,但其作用机制尚未完全阐明。
目的:通过生物信息学结合分子动力学模拟技术探索飞龙掌血治疗类风湿性关节炎的潜在机制。
方法:检索飞龙掌血的活性成分及其靶点,将药物靶点与类风湿性关节炎相关靶点取交集,对交集基因进行富集分析,通过分子对接与分子动力学模拟,验证飞龙掌血核心活性成分与类风湿性关节炎相关交集特征基因的结合机制。
结果与结论:通过文献检索筛选获得飞龙掌血的22种核心活性成分及其抗类风湿性关节炎治疗的关键靶点。富集分析表明,飞龙掌血可能通过调控疾病相关信号通路(包括癌症、感染性疾病、代谢性疾病和心血管疾病相关通路)以及与代谢、免疫和炎症相关的生物学通路,介导治疗作用。同时,飞龙掌血的主要成分Dihydrochelerythrine(二氢白屈菜红碱)和8-Methoxychelerythrine(8-甲氧基白屈菜红碱)可分别特异性靶向磷脂酶C γ 2(PLCG2)和丝裂原活化蛋白激酶8(MAPK8)蛋白,表明飞龙掌血可能通过多通路协同发挥抗类风湿性关节炎作用。

Abstract: BACKGROUND: The therapeutic potential of Toddalia asiatica in rheumatoid arthritis has garnered increasing attention, yet its mechanisms remain incompletely elucidated.
OBJECTIVE: To investigate the underlying mechanisms of Toddalia asiatica in treating rheumatoid arthritis using bioinformatics combined with molecular dynamics simulation.
METHODS: Active ingredients of Toddalia asiatica and their targets were retrieved. Drug targets were intersected with rheumatoid arthritis-related targets, followed by enrichment analysis of the overlapping genes. Molecular docking and molecular dynamics simulations were employed to validate the binding mechanisms between core active ingredients of Toddalia asiatica and key overlapping genes.
RESULTS AND CONCLUSION: Twenty-two core active ingredients of Toddalia asiatica and their key targets for rheumatoid arthritis treatment were identified through literature screening. Enrichment analysis revealed that Toddalia asiatica likely mediates therapeutic effects by regulating disease-associated signaling pathways (including cancer, infectious diseases, metabolic disorders, and cardiovascular pathways) and biological processes related to metabolism, immunity, and inflammation. Additionally, the main components dihydrochelerythrine and 8-methoxychelerythrine specifically target phospholipase C gamma-2 (PLCG2) and mitogen-activated protein kinase 8 proteins, respectively, indicating that Toddalia asiatica may exert anti-rheumatoid arthritis effects through multi-pathway synergy.

Key words: Toddalia asiatica, rheumatoid arthritis, network pharmacology, molecular dynamics simulation, PLCG2
