Background

Traditional Chinese medicine (TCM) syndrome, also known as ZHENG, represents a fundamental concept in TCM. It summarizes the pathological changes of a disease at specific stages of its development. Liver and kidney Yin deficiency syndrome (LKYDS), one of a pathologic and diagnostic pattern caused by the imbalance of Yin and Yang. Ligustri Lucidi Fructus (LLF) is the dried mature fruit of Ligustrum lucidum Ait. It has the effects of nourishing the liver and kidneys. To screen the active ingredients of LLF for treating liver and kidney yin deficiency based on network pharmacology and to explore their potential targets and mechanisms.

Methods

We obtained disease-related targets through GeneCards and DisGeNET databases, and utilized Venny 2.1.0 to obtain targets at the intersection of components and diseases. Protein-protein interaction (PPI) analysis and GO function and KEGG pathway enrichment analysis were performed on the potential targets with the help of STRING and DAVID databases, respectively. To clarify the biological process and pathway information, which were further visualized by using the microbiology platform. 120 male SD rats were randomly divided into a blank group, a model group, a raw product group, a processed product group, and a positive group for in vivo experiments. A liver and kidney yin deficiency model induced by levothyroxine sodium was established and continuously administered for 14 days. After the last administration, measure the thymus index, as well as the levels of ALT, AST, ALP, TP, ALB, CREA, UREA, and UA.

Results

LLF contains to 63 active components, 511 component targets, 1467 liver-related disease targets, 164 potential targets, 3571 kidney-related disease targets, 292 potential targets. GO functional enrichment involves negative regulation of protein phosphorylation, response to xenobiotic stimuli, apoptotic process, etc. KEGG signaling pathway involves lipids and atherosclerosis, PI3K-Akt signaling pathway and so on. Compared with the blank group, the model group rats showed weight loss, significant thymus atrophy, and a significant decrease in thymus index. The levels of ALT, AST, ALP, CREA, UREA, UA, TP and cGMP were significantly increased, while the levels of cAMP, ALB and cAMP/cGMP were significantly decreased. Compared with the model group, both the positive group and each treatment group showed an increase in thymus index, which significantly reduced the levels of ALT, AST, ALP, CREA, UREA, UA, TP and cGMP in the serum of rats, and significantly increased the levels of cAMP, ALB and cAMP/cGMP. Moreover, there were certain differences between the processed and raw products of LLF. Compared with the raw group, processed LLF showed better effects in ALT, ALB, UREA, TP, cAMP, cAMP/cGMP and other aspects.

Conclusions

The main active ingredients in LLF may participate in

All over the world, breast cancer is one of the most common cancers in women and is identified as the prevalent cause of death. Hence, the urgency of developing novel anti-breast cancer drugs for combating this deadly disease with potential efficiency is associated with current therapeutics. To address this issue, in our present work we collected recently analyzed 173 compounds from the scientific literature as much information as possible during 2021–2024 for the first time to elucidate the underlying molecular mechanisms associated with breast cancer via comprehensive analysis that integrates network pharmacology, molecular docking, molecular dynamics, and Molecular Mechanics with Generalized Born and Surface Area solvation (MM/GBSA). Molecular properties and drug-likeness were screened for obtained compounds to probe into the mechanism of action. The compound-target network, protein-protein interaction (PPI) network, Gene Ontology (GO) functional enrichment, and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis were performed with the aim of analyzing molecular mechanisms associated with breast cancer. Afterward, 12 potentially active compounds were carefully identified along with 192 common targets, including 8 pertinent core targets such as PIK3R1, PIK3CB, PIK3CA, PIK3CD, AKT1, AKT2, AKT3, and PTPN11. Molecular docking simulations revealed a robust score between AKT1-Capivasertib, PTPN11-Olaparib, PIK3R1-(1S)-2-(4-phenylmethoxyphenyl)-N-(pyridin-2-ylmethyl)cyclopropan-1-amine, PIK3CA-(1S)-2-(4-phenylmethoxyphenyl)-N-(pyridin-2-ylmethyl)cyclopropan-1-amine, PIK3CB-Capivasertib, AKT2-Ibuprofen Sodium, PIK3CD-Capivasertib and AKT3-N-(2-Hydroxyphenyl)-2-propylpentanamide complexes with strong binding interactions of 9.2353, 9.2016, 8.7742, 7.8234, 7.7083, 7.6387, 7.3778 and 6.6705, respectively. The key findings of outcome are corroborated by molecular dynamics simulation at 300 K for 200 ns to reinforce intermolecular mechanism between pertinent core targets and potential active compounds. In addition, overall free binding energy is calculated for eight complexes employing MM/GBSA, and the results indicate that Capivasertib has energetically favourable binding towards PIK3CD with binding free energy of −41.14 kcal/mol. Finally, the light of these results provides new insights into understanding the mechanism of action, including compounds, targets, potent biological processes, cellular components, molecular functions, and pathways involved that may represent an essential part of current breast cancer therapeutics.
在世界各地,乳腺癌是妇女最常见的癌症之一,被确定为主要的死亡原因。因此,迫切需要开发新的抗乳腺癌药物,以对抗这种致命的疾病,并具有潜在的有效性,这与目前的治疗方法有关。为了解决这一问题,在本研究中,我们首次从科学文献中收集和分析了2021-2024年间尽可能多的173种化合物,通过综合网络药理学、分子对接、分子动力学和分子力学与广义Born和Surface Area溶剂化(MM/GBSA)的综合分析来阐明与乳腺癌相关的潜在分子机制。对所得化合物进行分子性质和药物相似性筛选,探讨其作用机制。通过化合物-靶点网络、蛋白-蛋白相互作用(PPI)网络、基因本体(GO)功能富集和京都基因与基因组百科全书(KEGG)途径富集分析,分析乳腺癌相关的分子机制。随后,我们仔细鉴定了12种潜在活性化合物和192个共同靶点,包括8个相关核心靶点,如PIK3R1、PIK3CB、PIK3CA、PIK3CD、AKT1、AKT2、AKT3和PTPN11。分子对接模拟显示,AKT1-Capivasertib、PTPN11-Olaparib、PIK3R1-(1S)-2-(4-苯基甲氧基苯基)- n-(吡啶-2-甲基)环丙-1胺、PIK3CA-(1S)-2-(4-苯基甲氧基苯基)- n-(吡啶-2-甲基)环丙-1胺、PIK3CB-Capivasertib、akt2 -布洛芬钠、PIK3CD-Capivasertib和AKT3-N-(2-羟基苯基)-2-丙基戊酰胺配合物之间的结合相互作用分别为9.2353、9.2016、8.7742、7.8234、7.7083、7.6387、7.3778和6.6705。通过300 K、200 ns的分子动力学模拟验证了主要研究结果,以强化相关核心靶点与潜在活性化合物之间的分子间机制。此外,计算了8种配合物的总自由结合能,结果表明Capivasertib与PIK3CD具有良好的结合能,结合自由能为- 41.14 kcal/mol。最后,这些结果为理解作用机制提供了新的见解,包括化合物、靶点、有效的生物过程、细胞成分、分子功能和相关途径,这些可能是当前乳腺癌治疗的重要组成部分。

Pseudomonas syringae pv. actinidiae (Psa), the pathogen that causes bacterial canker disease in kiwifruit, has brought about substantial losses to the kiwifruit industry. Investigating the infection process at both the cellular and microscopic levels is of great significance for the formulation of effective control strategies against this disease. Thus, the establishment of appropriate chemical imaging analysis methods becomes essential. Confocal Raman microspectral imaging (CRMI), combined with chemometrics, provides an intuitive means to visualize and characterize the spatiotemporal changes of biopolymers in the cell walls of both healthy and infected kiwifruit stems. Raman spectra of different infected stems exhibit clustering effects in principal component analysis (PCA), and a classification model constructed using support vector machines (SVM) achieves an accuracy of 97 %. Multivariate Curve Resolution-Alternating Least Squares (MCR-ALS) is utilized to resolve spectral matrices and concentration profiles from raw Raman imaging signals. The reconstructed concentration data yields accurate molecular imaging maps of high-methylated pectin (HMP), low-methylated pectin (LMP), cellulose, hemicellulose, and lignin. The results indicate that, three days after Psa infection, the content of cellulose and HMP in the cell wall increases, while the changes in hemicellulose, lignin, and LMP are minimal. However, five days after infection, the contents of HMP, LMP, cellulose, hemicellulose, and lignin decrease significantly, resulting in the disruption of the cell-wall structure. The chemical imaging method proposed in this study shows great promise as an effective means for studying the bacterial infection process in kiwifruit stems at the cellular level.
丁香假单胞菌。猕猴桃细菌性溃疡病的病原菌猕猴桃酸菌(actinidiae, Psa)给猕猴桃产业带来了巨大的损失。从细胞和微观层面研究感染过程对制定有效的控制策略具有重要意义。因此,建立合适的化学成像分析方法变得至关重要。共聚焦拉曼微光谱成像(CRMI)与化学计量学相结合,提供了一种直观的方法来可视化和表征健康和感染猕猴桃茎中细胞壁中生物聚合物的时空变化。不同感染茎的拉曼光谱在主成分分析(PCA)中表现出聚类效应,使用支持向量机(SVM)构建的分类模型准确率达到97%。多元曲线分辨率-交替最小二乘法(MCR-ALS)被用于从原始拉曼成像信号中解析光谱矩阵和浓度分布。重建的浓度数据产生高甲基化果胶(HMP)、低甲基化果胶(LMP)、纤维素、半纤维素和木质素的精确分子成像图谱。结果表明,Psa感染3天后,细胞壁中纤维素和HMP含量增加,而半纤维素、木质素和LMP含量变化最小。但在感染5天后,HMP、LMP、纤维素、半纤维素和木质素的含量显著降低,导致细胞壁结构破坏。本研究提出的化学成像方法有望成为研究猕猴桃茎部细菌侵染过程的有效手段。

Psoriasis is an inflammatory immune skin disease with high incidence worldwide. As a traditional Chinese medicine (TCM), Huaier has a variety of pharmacological effects such as immune regulation and anti-inflammation. The aim of this study is to investigate the mechanism of action of Huaier on psoriasis and provide direction and basis for the treatment of psoriasis. Human keratinocyte (HaCaT) cells are frequently investigated as a target for psoriasis. Previous studies have found that Huaier can inhibit the proliferation and activity of HaCaT cells, and arrest the cell cycle of HaCaT cells in G1 phase, but the mechanism is still unclear. The aim of this study was to elucidate the role of Huaier in inhibiting the proliferation of HaCaT cells and to analyze its potential targets and molecular mechanisms. At different concentrations of Huaier, compared with the control group, Huaier significantly inhibited the proliferation and activity of HaCaT cells in a concentration-dependent manner (p < 0.05). The results of transcriptome sequencing analysis after Huaier treatment at IC50 concentration showed that Huaier significantly changed the expression of 103 genes in HaCaT cells and regulated 15 signaling pathways (p < 0.05). The results of correlation analysis showed that Huaier may regulate the IL-17 signaling pathway, which is important in the pathogenesis of psoriasis, by affecting the expression of key genes such as IL-6, ARRB1, CDH5, MYH11 and PPP3R1, and inhibit the activity of HaCaT cells, thus exerting a potential therapeutic effect on psoriasis.This will provide clues and directions for the treatment of psoriasis with TCM.
银屑病是一种世界性的高发炎性免疫皮肤病。怀尔是一种中药,具有免疫调节、抗炎等多种药理作用。本研究旨在探讨怀尔对银屑病的作用机制,为银屑病的治疗提供指导和依据。人类角化细胞(HaCaT)细胞经常作为银屑病的靶点进行研究。既往研究发现怀尔能抑制HaCaT细胞的增殖和活性,将HaCaT细胞的细胞周期阻滞在G1期,但机制尚不清楚。本研究旨在阐明槐儿在抑制HaCaT细胞增殖中的作用,并分析其潜在靶点和分子机制。在不同浓度的槐耳中,与对照组相比,槐耳显著抑制HaCaT细胞的增殖和活性,并呈浓度依赖性(p <;0.05)。IC50浓度的淮儿处理后转录组测序分析结果显示,淮儿显著改变了HaCaT细胞中103个基因的表达,调控了15条信号通路(p <;0.05)。相关分析结果显示,怀尔可能通过影响IL-6、ARRB1、CDH5、MYH11、PPP3R1等关键基因的表达,调控银屑病发病机制中重要的IL-17信号通路,抑制HaCaT细胞的活性,从而对银屑病发挥潜在的治疗作用。这将为银屑病的中医治疗提供线索和方向。

Belamcanda chinensis (BC) is a traditional Chinese herbal medicine with a long history of use. However, there are few studies investigating the variations in chemical composition between unprocessed and processed BC. This study aimed to identify the differential compounds present after the processing of BC and to establish a scientific basis for optimizing its processing technology and quality control. In this study, three types of processed BC products were prepared based on relevant literature and historical texts: water extract of rice-processed (RB), leaves of Phyllostachys bambusoides Sieb. et Zucc-processed (PB), and a combination of water extract of rice with leaves of Phyllostachys bambusoides Sieb. et Zucc-processed (RPB). Ultra performance liquid chromatography (UPLC) fingerprint analysis was performed on an Agilent 1290 liquid chromatograph to evaluate the similarity of the 10 principal flavonoids among different BC samples. Additionally, an untargeted metabolomics approach using ultra-high performance liquid chromatography-quadrupole time-of-flight mass spectrometry (UPLC-QTOF-MS) was utilized to identify differential metabolites. Fingerprint analysis showed no significant differences in the 10 main flavonoids between unprocessed and processed samples. Untargeted metabolomics identified 85 differential metabolites, with 57, 60, and 63 metabolites detected in the RB, PB, and RPB processed groups, respectively. Compared with raw BC, the RB group showed increased levels of 16 metabolites and decreased levels of 41; the PB group exhibited 11 upregulated and 49 downregulated metabolites; while the RPB group demonstrated 15 elevated and 48 reduced metabolites. Among these processed groups, PB and RPB exhibited more similar metabolic profiles compared to RB. These findings represent the first systematic investigation into the chemical composition of processed BC, thereby addressing a critical gap in the existing research. Furthermore, they establish a scientific foundation for optimizing processing techniques and enhancing quality control, while also contributing to the modernization and reinterpretation of traditional processing theories.
Belamcanda chinensis (BC)是一种具有悠久使用历史的传统中草药。然而,很少有研究调查未加工和加工的BC之间化学成分的变化。本研究旨在鉴定BC加工后存在的差异化合物,为优化其加工工艺和质量控制提供科学依据。本研究根据相关文献和历史文献,制备了三种加工产品:米加工水提物(RB)、竹竹叶(Phyllostachys bambusoides Sieb)。大米水提物与竹叶竹叶的复配。等zucc加工(RPB)。在Agilent 1290液相色谱上进行超高效液相色谱(UPLC)指纹图谱分析,评价不同BC样品中10种主要黄酮类化合物的相似性。此外,利用超高效液相色谱-四极杆飞行时间质谱(UPLC-QTOF-MS)的非靶向代谢组学方法来鉴定差异代谢物。指纹图谱分析显示,未加工和加工样品中10种主要黄酮类化合物含量无显著差异。非靶向代谢组学鉴定出85种差异代谢物,在RB、PB和RPB处理组中分别检测到57、60和63种代谢物。与生BC相比,RB组16种代谢物水平升高,41种代谢物水平降低;PB组代谢产物上调11种,下调49种;而RPB组显示15种代谢物升高,48种代谢物降低。在这些加工组中,与RB相比,PB和RPB表现出更相似的代谢谱。这些发现代表了对加工BC的化学成分的首次系统调查,从而解决了现有研究中的一个关键空白。此外,它们为优化加工技术和加强质量控制奠定了科学基础,同时也有助于传统加工理论的现代化和重新解释。

Alzheimer’s disease (AD) is a chronic neurodegenerative disorder for which traditional Chinese medicine (TCM) has shown potential therapeutic advantages. This study aimed to explore the medication patterns and core herbal pairs used in the treatment of AD by integrating data mining, network pharmacology, and molecular docking techniques. Relevant literature on TCM interventions for AD was retrieved from five major databases, and core herbal pairs were identified. To further investigate the multi-target and multi-pathway mechanisms of these pairs and their key components, a comprehensive network was constructed. A core herbal pair—Acori Tatarinowii Rhizoma-Polygalae Radix was selected, and its component–target–pathway network was established. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analyses were conducted to elucidate biological functions and signaling pathways, while molecular docking was performed to validate the interactions between key compounds and their targets. A total of 482 TCM formulas for AD were analyzed, identifying Acori Tatarinowii Rhizoma-Polygalae Radix as the most representative core pair. Its major active components, including phenylpropanoids (e.g., caffeic acid, β-asarone) and saponins (e.g., tenuigenin), were found to modulate inflammation, apoptosis, and synaptic plasticity through critical pathways such as MAPK and PI3K-Akt. Molecular docking demonstrated strong binding affinities between these key components and pivotal targets such as AKT1 and MAPK3. This study establishes a multi-layered framework, from big data analysis to functional validation of specific components, offering a clear pathway for investigating the structure-effect relationships in TCM. Furthermore, it proposes an innovative computational approach for analyzing the complex mechanisms of TCM, providing new insights into optimizing TCM formulations and developing novel drugs for AD.
阿尔茨海默病(AD)是一种慢性神经退行性疾病,中医药已显示出潜在的治疗优势。本研究旨在结合数据挖掘、网络药理学和分子对接技术,探索治疗AD的用药模式和核心中药对。从5个主要数据库中检索中药干预AD的相关文献,并确定核心中药对。为了进一步研究这些基因对及其关键成分的多靶点、多通路机制,我们构建了一个完整的网络。选取了核心中药对——石菖蒲-白芷,建立了其组分-靶点-通路网络。通过基因本体(GO)和京都基因与基因组百科全书(KEGG)富集分析来阐明其生物学功能和信号通路,通过分子对接来验证关键化合物与其靶点之间的相互作用。共对482个治疗AD的中药方剂进行了分析,确定了最具代表性的核心对为石菖子-茯苓。其主要活性成分包括苯丙素(如咖啡酸、β-细辛酮)和皂苷(如黄芪黄素),通过MAPK和PI3K-Akt等关键通路调节炎症、细胞凋亡和突触可塑性。分子对接表明,这些关键成分与关键靶点如AKT1和MAPK3之间具有很强的结合亲和力。本研究建立了从大数据分析到特定成分功能验证的多层次框架,为中医构效关系的研究提供了清晰的途径。此外,它还提出了一种创新的计算方法来分析中药的复杂机制,为优化中药配方和开发新型AD药物提供了新的见解。

The dried and matured pericarp of Citrus reticulata 'Chachi' (CRC), also known as Pericarpium Citri Reticulatae Chachiensis, is a traditional Chinese medicine renowned for its expectorant properties and extensively studied for its efficacy in alleviating cough and asthma symptoms. Ensuring the quality control of fresh CRC is crucial for its efficacy and safety. This study evaluated the quality and efficacy of CRC from the main production areas in Xinhui District. First, multi-wavelength fusion technology was employed to establish ultra high performance liquid chromatography (UHPLC) fingerprint analysis. Second, the in vitro antioxidant activity of fresh CRC peel samples was assessed using DPPH (2,2-diphenyl-1-picrylhydrazyl) and ABTS (2,2′-azinobis (3-ethylbenzothiazoline-6-sulfonic acid)) scavenging assays. Additionally, grey relational analysis (GRA) and partial least squares (PLS) modeling were used to correlate fingerprint patterns with efficacy parameters. Eleven major flavonoid compounds and total flavonoids were quantified across 26 samples. Finally, technique for order preference by similarity to ideal solution (TOPSIS) analysis comprehensively evaluated the overall quality of fresh CRC peels from these production areas. The results demonstrated a high degree of similarity among the 26 samples, ranging from 0.850 to 0.997. Notably, 21 peaks were identified as significant contributors (variable importance in the projection (VIP) > 0.7), including hesperidin, didymin, 3′-demethylnobiletin, and demethylnobiletin. Furthermore, TOPSIS and entropy weight analysis indicated that Gujing, Daze, and Luokeng exhibited superior overall quality. This study provides scientific evidence to support quality control and efficacy evaluation of fresh CRC peels.

Objective

To investigate the mechanism of Radix Rehmanniae Praeparata (RRP) in treating blood deficiency syndrome (BDS) by analyzing the changes in chemical components before and after processing, and its effects on metabolomics and gut microbiota in BDS mice.

Methods

Ultra-high-performance liquid chromatographyquadrupole time-of-flight mass spectrometry (UPLC-Q-TOF-MS) was employed to screen differential components before and after the processing of Radix Rehmanniae (RR). Pharmacodynamic studies were conducted to validate the therapeutic effects. Additionally, UPLC-Q-TOF-MS, headspace sampling-gas chromatography-mass spectrometry (HS-GC-MS), and 16sRNA sequencing were used to investigate the regulatory effects of RRP on metabolomics and the gut microbiota in BDS mice.

Results

The primary differential components identified were iridoids, phenylethanoid glycosides, sugars, benzaldehydes, and 5-hydroxymethylfurfural and its derivatives. RRP effectively ameliorated blood and energy metabolism in BDS mice. It regulates the biosynthesis pathway of unsaturated fatty acids, increases the abundance of Firmicutes to elevate butyric acid levels, and reduces the abundance of Bacteroidetes to downregulate acetic and propionic acid levels, thereby exerting therapeutic effects on BDS.

Conclusion

RRP attenuated the metabolic state of BDS mice by modulating metabolic pathways and gut microbiota balance, providing a scientific basis for its clinical application.

Hyperuricemia arises from an imbalance between uric acid production and excretion, resulting in elevated systemic uric acid levels. Consequently, therapeutic strategies targeting both production and excretion pathways offer a promising approach for managing hyperuricemia. TongFengTangSan (TFTS) has been frequently utilized as the Tibetan prescription in treating hyperuricemia or gout, and its anti-hyperuricemia effect has been confirmed in our previous study. However, the urate-lowering components still remain unclear. Therefore, an integrative strategy was constructed to screen potential urate-lowering components from TFTS by combination with affinity ultrafiltration, molecular docking and in vitro validation. In the present study, the main active fraction of TFTS with xanthine oxidase inhibitory effect was screened out by xanthine oxidase inhibitory assay. The potential ligands in main active fraction were identified by affinity ultrafiltration experiment combined with enzyme channel blocking technology and explored by ultra-high performance liquid chromatography-linear ion trap-Orbitrap mass spectrometry. Then, the screened ligands were further validated by in vitro xanthine oxidase inhibitory assay and molecular docking technique. Furthermore, the regulation effect on uric acid transporters of xanthine oxidase inhibitors was further evaluated by the over-expression of uric acid transporters in uric acid stimulated human Kidney-2 cell model by Western blot assay. In this study, the 60% ethanol-eluted fraction from the ethanol extract of TFTS was confirmed as the main fraction of TFTS with the best xanthine oxidase inhibitory effect. Three potential xanthine oxidase inhibitors were screened out from the 60% ethanol-eluted fraction, including 1,3,6-trigalloylglucose, 1,2,3,6-tetragalloylglucose and 1,2,3,4,6-pentagalloylglucose. Half maximal inhibitory concentration values of 1,3,6-trigalloylglucose, 1,2,3,6-tetragalloylglucose and 1,2,3,4,6-pentagalloylglucose for xanthine oxidase were 54.46, 15.91, 6.58 μg/mL, respectively. 1,3,6-trigalloylglucose, 1,2,3,6-tetragalloylglucose and 1,2,3,4,6-pentagalloylglucose were identified as mixed-type xanthine oxidase inhibitors. Additionally, these compounds demonstrated inhibitory effects on urate transporters 1 and glucose transporter 9. The combination strategy is suitable for screening active components with dual properties of inhibiting uric acid production and promoting uric acid excretion. 1,3,6-trigalloylglucose, 1,2,3,6-tetragalloylglucose and 1,2,3,4,6-pentagalloylglucose were identified as a potential urate-lowering drug and exhibited dual-target characteristics in uric acid metabolism.
高尿酸血症是由尿酸产生和排泄失衡引起的,导致全身尿酸水平升高。因此,针对生产和排泄途径的治疗策略为治疗高尿酸血症提供了一种有希望的方法。痛风汤散是治疗高尿酸血症或痛风的常用藏方,其抗高尿酸血症的作用已被我们的前期研究证实。然而,降低尿酸的成分仍然不清楚。为此,构建了亲和超滤、分子对接和体外验证相结合的综合策略,筛选TFTS中潜在的降尿酸成分。本研究通过黄嘌呤氧化酶抑制实验筛选出具有黄嘌呤氧化酶抑制作用的黄芪多糖主要活性部位。采用亲和超滤实验结合酶通道阻断技术鉴定了主要活性部位的潜在配体,并采用超高效液相色谱-线性离子阱-轨道阱质谱法对其进行了探索。然后,通过体外黄嘌呤氧化酶抑制实验和分子对接技术进一步验证筛选到的配体。通过Western blot检测尿酸刺激人肾-2细胞模型中尿酸转运蛋白的过表达,进一步评价黄嘌呤氧化酶抑制剂对尿酸转运蛋白的调节作用。本研究确定了黄嘌呤氧化酶抑制效果最好的黄嘌呤氧化酶主要部位为黄嘌呤提取物60%乙醇洗脱部位。从60%乙醇洗脱的部分中筛选出3种潜在的黄嘌呤氧化酶抑制剂,分别为1,3,6-三烯基葡萄糖、1,2,3,6-四烯基葡萄糖和1,2,3,4,6-五烯基葡萄糖。1,3,6-三烯丙基葡萄糖、1,2,3,6-四烯丙基葡萄糖和1,2,3,4,6-五烯丙基葡萄糖对黄嘌呤氧化酶的半数最大抑制浓度分别为54.46、15.91、6.58 μg/mL。1,3,6-三烯丙基葡萄糖、1,2,3,6-四烯丙基葡萄糖和1,2,3,4,6-五烯丙基葡萄糖被鉴定为混合型黄嘌呤氧化酶抑制剂。此外,这些化合物对尿酸转运蛋白1和葡萄糖转运蛋白9有抑制作用。该组合策略适合筛选具有抑制尿酸生成和促进尿酸排泄双重特性的活性成分。1,3,6-三烯丙基葡萄糖、1,2,3,6-四烯丙基葡萄糖和1,2,3,4,6-五烯丙基葡萄糖被认为是一种潜在的降尿酸药物,在尿酸代谢中表现出双靶点特征。

Then, the screened ligands were further validated by <em>in vitro</em> xanthine oxidase inhibitory assay and molecular docking technique. Furthermore, the regulation effect on uric acid transporters of xanthine oxidase inhibitors was further evaluated by the over-expression of uric acid transporters in uric acid stimulated human Kidney-2 cell model by Western blot assay. In this study, the 60% ethanol-eluted fraction from the ethanol extract of TFTS was confirmed as the main fraction of TFTS with the best xanthine oxidase inhibitory effect. Three potential xanthine oxidase inhibitors were screened out from the 60% ethanol-eluted fraction, including 1,3,6-trigalloylglucose, 1,2,3,6-tetragalloylglucose and 1,2,3,4,6-pentagalloylglucose. Half maximal inhibitory concentration values of 1,3,6-trigalloylglucose, 1,2,3,6-tetragalloylglucose and 1,2,3,4,6-pentagalloylglucose for xanthine oxidase were 54.46, 15.91, 6.58 μg/mL, respectively. 1,3,6-trigalloylglucose, 1,2,3,6-tetragalloylglucose and 1,2,3,4,6-pentagalloylglucose were identified as mixed-type xanthine oxidase inhibitors. Additionally, these compounds demonstrated inhibitory effects on urate transporters 1 and glucose transporter 9. The combination strategy is suitable for screening active components with dual properties of inhibiting uric acid production and promoting uric acid excretion. 1,3,6-trigalloylglucose, 1,2,3,6-tetragalloylglucose and 1,2,3,4,6-pentagalloylglucose were identified as a potential urate-lowering drug and exhibited dual-target characteristics in uric acid metabolism.</div></div>","PeriodicalId":277,"journal":{"name":"Chinese Journal of Analytical Chemistry","volume":"53 7","pages":"Article 100551"},"PeriodicalIF":1.2,"publicationDate":"2025-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144170000","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Background

Respiratory syncytial virus (RSV) is one of the leading pathogens associated with hospitalization for childhood pneumonia and is associated with substantial morbidity and fatality among young children and infants. There are no specific antiviral treatments for RSV infections. Kaempferol, a flavonoid present in traditional Chinese medicines, possesses antiviral activity and may affect RSV-induced lung inflammation; however, this relationship remains unclear.

Methods

We employed network pharmacology to forecast the mechanism of kaempferol in the treatment of RSV pneumonia, and used gas chromatography-mass spectrometry (GC-MS) to examine the metabolic profiles in serum. We then integrated the analysis of differential metabolites with potential targets using MetScape and assessed the interactions between kaempferol and the key targets through molecular docking. Molecular biology experiments confirmed these predictions.

Results

Our results demonstrated that kaempferol alleviated RSV-induced lung inflammation, inhibited viral replication, and reduced lung damage, possibly by modulating the JAK-STAT signaling pathway. Kaempferol primarily alleviates metabolic disorders by targeting amino acid metabolism. Molecular docking analysis indicated a strong binding affinity of kaempferol for AKT1, CASP3, SRC, EGFR, STAT1, and IL-2.

Conclusion

Kaempferol ameliorated the metabolic disruptions caused by RSV in the amino acid metabolism, via the JAK-STAT signaling cascade and mitigated the inflammatory response associated with RSV infection. This study not only provides foundational data for the broad application of kaempferol in anti-RSV research but also offers novel insights into the exploration of therapeutic mechanisms for RSV infections.
呼吸道合胞病毒(RSV)是与儿童肺炎住院相关的主要病原体之一,并与幼儿和婴儿的大量发病率和病死率相关。目前还没有针对呼吸道合胞病毒感染的抗病毒治疗方法。山奈酚是一种存在于中药中的类黄酮,具有抗病毒活性,可能影响rsv诱导的肺部炎症;然而,这种关系尚不清楚。方法采用网络药理学方法预测山奈酚治疗呼吸道合胞病毒肺炎的作用机制,并采用气相色谱-质谱联用技术检测血清代谢谱。然后,我们利用MetScape将差异代谢物与潜在靶点的分析结合起来,通过分子对接评估山奈酚与关键靶点之间的相互作用。分子生物学实验证实了这些预测。结果山奈酚可减轻rsv诱导的肺部炎症,抑制病毒复制,减轻肺损伤,可能与调节JAK-STAT信号通路有关。山奈酚主要通过靶向氨基酸代谢来缓解代谢紊乱。分子对接分析表明山奈酚对AKT1、CASP3、SRC、EGFR、STAT1和IL-2具有较强的结合亲和力。结论山奈酚通过JAK-STAT信号级联改善RSV引起的氨基酸代谢紊乱,减轻RSV感染相关的炎症反应。本研究不仅为山奈酚在抗RSV研究中的广泛应用提供了基础数据,而且为探索RSV感染的治疗机制提供了新的见解。
