Objective

This study is designed to investigate the mode of action of the synergistic effect of 5-fluorouracil (5-FU) and magnolol against cervical cancer.

Methods

Network pharmacological approach was applied to predict the molecular mechanism of 5-FU combined with magnolol against cervical cancer. CCK-8 assay, colony formation assay, immunofluorescence staining, adhesion assay, wound healing mobility assay, cell migration and invasion assay and Western blot analysis were conducted to validate the results of in silico study.

Results

Phosphatidylinositol 3 kinase (PI3K)/protein kinase B (AKT)/mammalian target of rapamycin (mTOR) signaling pathway was identified as the key pathway in silico study. The experimental results showed that 5-FU combined with magnolol strongly inhibited cervical cancer cell proliferation, induced the morphological change of HeLa cells by down-regulating the expression of α-actinin, tensin-2 and vinculin. Moreover, magnolol enhanced inhibitory effect of 5-FU on the cell adhesion, migration and invasion. The phosphorylation of AKT and PI3K and the expression of mTOR were strongly inhibited by the combination of 5-FU and magnolol. Moreover, the expression of E-cadherin and β-catenin was upregulated and the expression of Snail, Slug and vimentin was down-regulated by the 5-FU together with magnolol.

Conclusion

Taken together, this study suggests that 5-FU combined with magnolol exerts a synergistic anti-cervical cancer effect by regulating the PI3K/AKT/mTOR and epithelial-mesenchymal transition (EMT) signaling pathways.

本研究旨在探讨 5-氟尿嘧啶(5-FU)与马格诺洛尔(magnolol)对宫颈癌的协同作用模式。方法应用网络药理学方法预测 5-FU 与马格诺洛尔联合治疗宫颈癌的分子机制。方法应用网络药理学方法预测 5-FU 联合马格诺洛尔治疗宫颈癌的分子机制,并通过 CCK-8 试验、菌落形成试验、免疫荧光染色、粘附试验、伤口愈合迁移率试验、细胞迁移和侵袭试验以及 Western 印迹分析来验证硅学研究的结果。实验结果表明,5-FU联合magnolol能强烈抑制宫颈癌细胞的增殖,并通过下调α-肌动蛋白、tensin-2和vinculin的表达诱导HeLa细胞的形态变化。此外,magnolol 还能增强 5-FU 对细胞粘附、迁移和侵袭的抑制作用。5-FU 和 magnolol 的联合作用强烈抑制了 AKT 和 PI3K 的磷酸化以及 mTOR 的表达。结论综上所述,本研究表明,5-FU 联合 magnolol 可通过调节 PI3K/AKT/mTOR 和上皮-间质转化(EMT)信号通路,发挥协同抗宫颈癌作用。

Objective

To identify phytochemical constituents present in the extract of flowers of Xanthoceras sorbifolia and evaluate their anti-oxidant and anti-hyperglycemic capacities.

Methods

The AlCl3 colorimetric method and Prussian Blue assay were used to determine the contents of total flavonoids and total phenolic acids in extraction layers, and the bioactive layers was screened through anti − oxidative activity in vitro. The Waters ACQUITY UPLC system and a Waters ACQUITY UPLC BEH C18 column (2.0 mm × 150 mm, 5 μm) were used to identify the ingredients. And anti-oxidative ingredients were screened by off-line UPLC-QTOF-MS/MS-free radical scavenging. The ameliorative role of it was further evaluated in a high-fat, streptozotocin-induced type 2 diabetic rat model and the study was carried out on NADPH oxidase (PDB ID: 2CDU) by molecular docking.

Results

Combined with the results of activity screening in vitro, the anti − oxidative part was identified as the ethyl acetate layer. A total of 24 chemical constituents were identified by liquid chromatography-mass spectrometry in the ethyl acetate layer and 13 main anti-oxidative active constituents were preliminarily screened out through off-line UPLC-QTOF-MS/MS-free radical scavenging. In vivo experiments showed that flowers of X. sorbifolia could significantly reduce the blood glucose level of diabetic mice and alleviate liver cell damage. Based on the results of docking analysis related to the identified phytocompounds and oxidase which involved in type 2 diabetes, quercetin 3-O-rutinoside, kaempferol-3-O-rhamnoside, isorhamnetin-3-O-glucoside, and isoquercitrin showed a better inhibitory profile.

Conclusion

The ethyl acetate layer was rich in flavonoids and phenolic acids and had significant anti-oxidant activity, which could prevent hyperglycemia. This observed activity profile suggested X. sorbifolia flowers as a promising new source of tea to develop alternative natural anti-diabetic products with a high safety margin.

方法采用AlCl3比色法和普鲁士蓝法测定提取物中总黄酮类化合物和总酚酸类化合物的含量,并通过体外抗氧化活性筛选生物活性层。采用 Waters ACQUITY UPLC 系统和 Waters ACQUITY UPLC BEH C18 色谱柱(2.0 mm × 150 mm, 5 μm)鉴定成分。并通过离线 UPLC-QTOF-MS/MS 无自由基清除法筛选抗氧化成分。结果结合体外活性筛选结果,确定抗氧化部分为乙酸乙酯层。通过液相色谱-质谱法鉴定了乙酸乙酯层中的 24 种化学成分,并通过离线 UPLC-QTOF-MS/MS 无自由基清除法初步筛选出 13 种主要的抗氧化活性成分。体内实验表明,山银花能显著降低糖尿病小鼠的血糖水平,减轻肝细胞损伤。根据所鉴定的植物化合物与 2 型糖尿病氧化酶的对接分析结果,槲皮素-3-O-芸香糖苷、山奈素-3-O-鼠李糖苷、异鼠李素-3-O-葡萄糖苷和异槲皮素具有较好的抑制作用。观察到的这一活性特征表明,X. sorbifolia 花是一种很有前景的新茶源,可用于开发安全系数高的天然抗糖尿病产品。

Objective

Cultivated Cordyceps sinensis powder has been used as clinical drug and healthy food to nourish the lung and kidney, which solves the problem of serious shortage of wild C. sinensis. This study aims to explore the chemical components and compared their anti-fibrotic effects in cultivated C. sinensis.

Methods

Nucleosides, sterols and polysaccharides were separated and purified from cultivated C. sinensis, and analyzed by high performance liquid chromatography, gas chromatography-mass spectrometry and chemical chromogenic methods, respectively. In high glucose-induced rat mesangial cell models, fibronectin and type 1 collagen were used as evaluation indicators.

Results

There were 10 kinds of nucleosides and one sterol in cultivated C. sinensis. The contents of nucleosides, sterols and polysaccharides in the cultivated C. sinensis were close to 2%, 0.55% and 4.4%, respectively. Furthermore, nucleoside, sterol and polysaccharide components exhibited varying degrees of anti-fibrotic activity. The nucleoside components and sterol components inhibited the expression of extracellular matrix more effectively in the three main components.

Conclusion

Cultivated C. sinensis remains the similar compounds with the wild C. sinensis, and nucleosides and sterols may be the main active substances that contribute to its anti-fibrotic effects. The project of this study may provide valuable information on further optimization of more effective remedies with few side effects based on cultivated C. sinensis.

目的人工栽培的冬虫夏草已作为临床药物和滋补肺肾的保健食品,解决了野生冬虫夏草严重缺乏的问题。方法从栽培冬虫夏草中分离纯化出核苷类、甾醇类和多糖类物质,分别用高效液相色谱法、气相色谱-质谱法和化学发色法进行分析。在高糖诱导的大鼠间质细胞模型中,以纤维粘连蛋白和 1 型胶原蛋白作为评价指标。其中核苷、甾醇和多糖的含量分别接近 2%、0.55% 和 4.4%。此外,核苷、甾醇和多糖成分均表现出不同程度的抗纤维化活性。结论中药材栽培种仍具有与野生中药材相似的化合物,核苷和甾醇可能是其抗纤维化作用的主要活性物质。本研究项目可为进一步优化基于栽培冬凌草的更有效且副作用小的疗法提供有价值的信息。

Objective

Based on metabonomics technology of high-performance liquid chromatography-mass spectrometry (HPLC-MS/MS) and hydrogen nuclear magnetic resonance spectroscopy (1H NMR), the pharmacokinetic characteristics and therapeutic mechanism of Rhei Radix et Rhizoma (RhRR, Dahuang in Chinese), Eupolyphaga Steleophaga (EuS, Tubiechong in Chinese) combined with RhRR acting on acute liver injury were explored.

Methods

Models of acute liver injury were established, and the pharmacokinetic methods of five components of RhRR-EuS in rats were found by HPLC-MS/MS. The liver tissues of different groups of mice were analyzed by 1H NMR spectroscopy combined with multivariate statistical analysis to investigate the metabolomics of RhRR-EuS and RhRR.

Results

Pharmacokinetic results showed there were different levels of bimodal phenomenon in different groups, and the absorption of free anthraquinone in RhRR increased after compatibility with EuS. In addition, the pathological state of acute liver injury in rats can selectively promote the absorption of emodin, chrysophanol, physcion and aloe emodin. Through 15 differential metabolites in the liver tissue of acute liver injury mice, it was revealed that RhRR-EuS and RhRR could protect the liver injury by regulating the metabolism of glutamine and glutamic acid, alanine, aspartic acid and glutamic acid, and phosphoinositide. However, the regulation of RhRR was weaker than that of RhRR-EuS.

Conclusion

For the first time, we studied the pharmacokinetics and metabolomics differences of RhRR-EuS and RhRR in rats and mice with acute liver injury, in order to provide theoretical reference for clinical treatment of liver disease by DHZCP.

目的 基于高效液相色谱-质谱(HPLC-MS/MS)和氢核磁共振波谱(1H NMR)的代谢组学技术,探讨大黄、大戟联合RhRR对急性肝损伤的药代动力学特征和治疗机制。方法建立急性肝损伤模型,采用 HPLC-MS/MS 方法测定 RhRR-EuS 五种成分在大鼠体内的药代动力学方法。结果药代动力学结果显示,RhRR-EuS和RhRR在不同组别中存在不同程度的双峰现象,RhRR中游离蒽醌与EuS相容后吸收增加。此外,大鼠急性肝损伤的病理状态可选择性地促进大黄素、金丝桃醇、黄柏醇和芦荟大黄素的吸收。通过对急性肝损伤小鼠肝组织中 15 种差异代谢产物的研究发现,RhRR-EuS 和 RhRR 可通过调节谷氨酰胺和谷氨酸、丙氨酸、天门冬氨酸和谷氨酸以及磷脂的代谢来保护肝损伤。结论首次研究了RhRR-EuS和RhRR在急性肝损伤大鼠和小鼠体内的药代动力学和代谢组学差异,为DHZCP临床治疗肝病提供理论参考。
