Lantana camara L. is widely used in folk medicine for alleviation of inflammatory disorders, but studies that proved this folk use and that revealed the molecular mechanism of action in inflammation mitigation are not enough. Therefore, this study aimed to identify L. camara phytoconstituents using UPLC-MS/MS and explain their multi-level mechanism of action in inflammation alleviation using network pharmacology analysis together with molecular docking and in vitro testing. Fifty-seven phytoconstituents were identified in L. camara extract, from which the top hit compounds related to inflammation were ferulic acid, catechin gallate, myricetin and iso-ferulic acid. Whereas the most enriched inflammation related genes were PRKCA, RELA, IL2, MAPK 14 and FOS. Furthermore, the most enriched inflammation-related pathways were PI3K-Akt and MAPK signaling pathways. Molecular docking revealed that catechin gallate possessed the lowest binding energy against PRKCA, RELA and IL2, while myricetin had the most stabilized interaction against MAPK14 and FOS. In vitro cytotoxicity and anti-inflammatory testing indicated that L. camara extract is safer than piroxicam and has a strong anti-inflammatory activity comparable to it. This study is a first step in proving the folk uses of L. camara in palliating inflammatory ailments and institutes the groundwork for future clinical studies.
马缨丹 L. 在民间医学中被广泛用于缓解炎症性疾病,但证明这种民间用途并揭示其在减轻炎症方面的分子作用机制的研究还不够。因此,本研究旨在使用 UPLC-MS/MS 鉴定 L. camara 的植物成分,并使用网络药理学分析结合分子对接和体外测试来解释其在炎症缓解方面的多层次作用机制。从马缨丹提取物中鉴定出 57 种植物成分,其中与炎症相关的顶级命中化合物为阿魏酸、没食子儿茶素酸、杨梅素和异阿魏酸。而最富集的炎症相关基因是 PRKCA、RELA、IL2、MAPK 14 和 FOS。此外,最富集的炎症相关途径是 PI3K-Akt 和 MAPK 信号通路。分子对接表明,没食子儿茶素酸对 PRKCA、RELA 和 IL2 具有最低的结合能,而杨梅素对 MAPK14 和 FOS 具有最稳定的相互作用。体外细胞毒性和抗炎试验表明,马缨丹提取物比吡罗昔康更安全,且具有与吡罗昔康相当的强大抗炎活性。本研究是证明马缨丹在缓解炎症性疾病方面的民间用途的第一步,并为未来的临床研究奠定了基础。
