摘要

为了从中药天麻中分离天麻素(GAS)、4-羟基苯甲醇(4-HBA)和酚类化合物,探索与巨噬细胞炎症密切相关的脂肪酸结合蛋白4(FABP4/aP2)的结合模式,研究其抗炎靶点。采用AB-8大孔树脂和硅胶柱色谱法,经CHCl3-MeOH梯度洗脱,从天麻中分离出天麻素、4-羟基苄醇等8种结构相似的酚类单体,并用高效液相色谱法鉴定了它们的结构。通过高效液相色谱和核磁共振(NMR)鉴定了它们的结构。将 FABP4 蛋白添加到 GAS 和 4-HBA 中,进行核磁共振实验观察配体结合情况。最后,根据 STD-NMR 的光谱信息和分子对接技术,研究了配体与蛋白质之间的相互作用。荧光竞争实验证实,GAS和4-HBA都在FABP4的结合腔中。此外,3-苯氧基-2-苯基苯甲酸(3-phenoxy-2-phenylbenzoic acid,PPA)可能是 FABP4 的抑制剂,能减轻巨噬细胞相关炎症和内质网应激。这项工作为天麻的抗炎机制提供了新的依据,为研究和开发FABP4抑制剂药物铺平了道路。

The Molecular Mechanism of FABP4 Inhibition Effects of GAS and 4-HBA in Gastrodia elata Blume Was Discussed Based on NMR and Molecular Docking
To isolate gastrodin (GAS), 4-hydroxybenzyl alcohol (4-HBA), and phenolic compounds from Chinese medicine Gastrodia elata Blume, and to explore the binding mode of fatty acid binding protein 4 (FABP4/aP2) that is closely related to macrophage inflammation, we study their anti-inflammatory targets. After the ultrasonic extraction of the main active components with 70% ethanol, three resins and three eluents were selected, and eight phenolic monomers with similar structures, such as gastrodin and 4-hydroxybenzyl alcohol, were isolated from Gastrodia elata by AB-8 macroporous resin and silica gel column chromatography and eluted with the CHCl3-MeOH gradient. Their structures were identified by HPLC and nuclear magnetic resonance (NMR). The FABP4 protein was added to GAS and 4-HBA, and the NMR experiment was performed to observe ligand binding. Finally, according to the spectral information of STD-NMR and molecular docking technology, the interaction between ligands and protein was studied. The fluorescence competition experiment confirmed that both GAS and 4-HBA were in the binding cavity of FABP4. Moreover, 3-phenoxy-2-phenylbenzoic acid (PPA) is a possible inhibitor of FABP4, reducing macrophage-related inflammation and endoplasmic reticulum stress. This work provides a new basis for the anti-inflammatory mechanism of Gastrodia elata, paving the way for the research and development of FABP4 inhibitor drugs.
