Ulcerative colitis (UC) is a common disease of the digestive system that is challenging to treat. Gegen Qinlian Decoction (GQD), which is an ancient classic formula in Chinese medicine, is effective at alleviating the symptoms of UC, but comprehensive research on its mechanism of action has not been performed. Here, we explored the material basis and potential molecular mechanism underlying GQD-mediated protection against UC by integrated metabolomics and network pharmacology. First, differentially expressed metabolites were screened and identified via a metabolomics approach, and the metabolic pathway was analyzed via MetaboAnalyst. Second, a protein-protein interaction (PPI) network was constructed to identify hub genes that encode metabolic enzymes. Third, the differentially expressed metabolites were used to construct a compound-reaction-enzyme-gene network. Finally, the metabolites were compared with relevant active components for molecular docking, molecular dynamics (MD) simulation, and verification experiment. GQD intervention alleviated UC in mice and significantly inhibited metabolic dysfunction in mice with UC; specifically, GQD reversed the abnormal changes in metabolites in the colon and serum, and regulated the arachidonic acid metabolism, tryptophan metabolism, glycerophospholipid metabolism, and purine metabolism pathways. Further literature review and molecular docking analysis with targeted MD simulation and Poisson-Boltzmann surface area (MM-PBSA) analysis were performed, revealing that GQD may inhibit the disruption of arachidonic acid metabolism and tryptophan metabolism by suppressing PTGS2 and CYP450 protein expression; these results were verified by qRT-PCR, WB, and surface plasmon resonance (SPR) assays. Our experiments indicated that GQD alleviated UC in mice by systematically regulating arachidonic acid metabolism and tryptophan metabolism, supporting further research and the development of GQD as a novel drug for ameliorating UC.

溃疡性结肠炎(UC)是一种常见的消化系统疾病,治疗难度很大。格根秦连煎(GQD)是中药中的经典古方,能有效缓解 UC 的症状,但有关其作用机制的全面研究尚未开展。在此,我们通过整合代谢组学和网络药理学,探索了GQD介导的保护UC的物质基础和潜在分子机制。首先,通过代谢组学方法筛选和鉴定了差异表达的代谢物,并通过 MetaboAnalyst 分析了代谢途径。其次,构建了蛋白质-蛋白质相互作用(PPI)网络,以确定编码代谢酶的枢纽基因。第三,利用差异表达的代谢物构建化合物-反应-酶-基因网络。最后,将代谢物与相关活性成分进行分子对接、分子动力学(MD)模拟和验证实验。GQD干预缓解了小鼠的UC症状,显著抑制了UC小鼠的代谢功能障碍;具体而言,GQD逆转了小鼠结肠和血清中代谢物的异常变化,调节了花生四烯酸代谢、色氨酸代谢、甘油磷脂代谢和嘌呤代谢途径。我们进一步查阅了文献,并通过定向 MD 模拟和泊松-波尔兹曼表面积(MM-PBSA)分析进行了分子对接分析,发现 GQD 可通过抑制 PTGS2 和 CYP450 蛋白表达来抑制花生四烯酸代谢和色氨酸代谢的紊乱;这些结果通过 qRT-PCR、WB 和表面等离子体共振(SPR)检测得到了验证。我们的实验表明,GQD可通过系统调节花生四烯酸代谢和色氨酸代谢来缓解小鼠的UC,这为进一步研究和开发GQD作为改善UC的新型药物提供了支持。

Furmonertinib (AST2818) is a selective epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor (TKI) being developed for the treatment of patients with EGFR mutation-positive non-small cell lung cancer. Quantification of furmonertinib in plasma and cerebrospinal fluid (CSF) can be used to assess penetration of furmonertinib into the central nervous system (CNS). This paper described ultra-performance liquid chromatography tandem mass spectrometry (UPLC-MS/MS) methods for quantification of furmonertinib in human plasma and CSF. Sample separation was achieved on a Kinetex C18 column (100 mm × 2.1 mm, 2.6 μm) after simple protein precipitation with acetonitrile. The mobile phase was composed of acetonitrile and 5 mM ammonium acetate with 0.2 % formic acid in water. Quantitative ion pairs were m/z 569.3 → 72.2 for furmonertinib and m/z 526.5 → 72.2 for aumolertinib, which was used as the internal standard (IS). The calibration curves showed good linearity (r2 > 0.99) over concentration range of 0.5–200 ng/mL(plasma sample) and 0.05–30 ng/mL(CSF sample). The precision (RSD) was ≤7.86 %, and the accuracy fell within the range of 96.2 %–109.3 %, all meeting acceptance criteria. The matrix effect was from 94.3 % to 102.1 %. The recovery of analytes fell within the range of 93.3 %–98.9 %. The established analytical methods showed great sensitivity, simplicity, accuracy and reliability for the analysis of furmonertinib in human plasma and CSF. This assay would be helpful to predict the effectiveness and toxicities of furmonertinib in the pursuit of precision medicine for lung cancer patients.
呋莫替尼 (AST2818) 是一种选择性表皮生长因子受体 (EGFR) 酪氨酸激酶抑制剂 (TKI),目前正在开发用于治疗 EGFR 突变阳性的非小细胞肺癌患者。血浆和脑脊液(CSF)中呋莫替尼的定量可用于评估呋莫替尼对中枢神经系统(CNS)的渗透。本文介绍了超高效液相色谱-串联质谱(UPLC-MS/MS)方法,用于定量检测人血浆和脑脊液中的呋莫尼替尼。样品经乙腈简单蛋白质沉淀后,在 Kinetex C18 色谱柱(100 mm × 2.1 mm, 2.6 μm)上分离。流动相为乙腈和 5 mM 乙酸铵加 0.2 % 甲酸水溶液。定量离子对为 m/z 569.3 → 72.2(呋莫替尼)和 m/z 526.5 → 72.2(奥莫替尼),后者被用作内标(IS)。在 0.5-200 纳克/毫升(血浆样品)和 0.05-30 纳克/毫升(脑脊液样品)的浓度范围内,校准曲线显示出良好的线性关系(r2 > 0.99)。精密度(RSD)≤7.86 %,准确度在 96.2 %-109.3 % 范围内,均符合接受标准。基质效应为 94.3 % 至 102.1 %。分析物的回收率在 93.3 % 至 98.9 % 之间。所建立的分析方法在分析人血浆和脑脊液中的呋喃替尼时显示出极高的灵敏度、简便性、准确性和可靠性。该检测方法有助于预测呋莫尼替尼的疗效和毒性,从而实现肺癌患者的精准医疗。

A Magnetic Molecularly Imprinted Polymer (MMIP) was developed using naringin as template molecule, acrylamide as functional monomer and polymerized by ultrasound irradiation for the adsorption of naringin. In an unexpected turn of results, the selectivity study unveiled that the synthesized MMIP exhibited a higher affinity for quercetin over naringin. Given this high selectivity, adsorption isotherm and kinetic studies were conducted for both quercetin and naringin. The adsorption isotherm indicated multilayer adsorption of the adsorbate on the adsorbent. The kinetic study showed better agreement with the pseudo-second-order kinetic model. The maximum adsorption capacity of 7.2 mg/g was achieved for quercetin at 50 mg/L and 4.9 mg/g was attained for naringin at the same concentration. Furthermore, quercetin quantification was performed by coupling MMIP with HPLC-UV, with method validation revealing the limits of detection (LOD) and quantification (LOQ) for quercetin. Additionally, agro-industrial waste onion peel, enriched with phenolic compounds such as quercetin, was subjected to solid-phase extraction using MMIP for the purification of quercetin.
以柚皮苷为模板分子,丙烯酰胺为功能单体,经超声波辐照聚合而成的磁性分子印迹聚合物(MMIP)吸附了柚皮苷。结果出人意料,选择性研究显示,合成的 MMIP 对槲皮素的亲和力高于柚皮素。鉴于这种高选择性,我们对槲皮素和柚皮苷进行了吸附等温线和动力学研究。吸附等温线表明吸附剂上存在多层吸附。动力学研究表明,与假二阶动力学模型的吻合度较高。在 50 mg/L 浓度下,槲皮素的最大吸附容量为 7.2 mg/g,在相同浓度下,柚皮苷的最大吸附容量为 4.9 mg/g。此外,通过将 MMIP 与 HPLC-UV 联用,对槲皮素进行了定量,方法验证显示了槲皮素的检出限(LOD)和定量限(LOQ)。此外,利用 MMIP 对富含槲皮素等酚类化合物的农用工业废洋葱皮进行固相萃取,以纯化槲皮素。

The recent pandemic has highlighted the impact of diseases on global health and the economy. The rapid discovery of new hit molecules remains a tough challenge. Pharmaceutical impurity profiling can be linked to drug discovery through the identification of new hits from compounds identified during the analytical profiling. The present study demonstrates this linkage through the extension of the impurity (forced degradation) profiling of eltrombopag (ELT) olamine, a thrombopoietin (TPO) receptor agonist. The drug was exposed to standard degradation and the degradation products were primarily resolved and identified by UPLC-ESI-MS. This led to the identification of five forced degradation products (FDP). Thirty-three other known related substances (RS) of ELT, identified in the literature, were also considered. Molecular similarity checks were performed using Tanimoto/Jaccard's similarity searches. A set of structurally and topologically similar molecules, including ELT and 15 RS, was established and subjected to in-silico toxicity-, absorption-, distribution-, metabolism-, and elimination (ADME) predictions. The RS, predicted with similar or lower toxicity than ELT and a comparable ADME profile, were subjected to molecular docking to trace changes in TPO receptor affinity. The results indicated that five RS had a high Jaccard’s similarity with ELT and higher or comparable docking scores. These compounds, along with few other impurities were predicted to have lower toxicity, better or comparable absorption, distribution, metabolism, and also a better excretion profile than ELT. This justifies their entry as potential novel TPO receptor agonists in drug discovery.
最近的大流行突显了疾病对全球健康和经济的影响。快速发现新的热门分子仍然是一项严峻的挑战。药物杂质分析可以通过从分析过程中发现的化合物中识别出新的热门分子,从而与药物发现联系起来。本研究通过扩展对凝血酶原(TPO)受体激动剂艾曲波帕(ELT)橄榄胺的杂质(强制降解)分析,证明了这种联系。对药物进行标准降解,降解产物主要通过 UPLC-ESI-MS 进行分辨和鉴定。最终确定了五种强制降解产物(FDP)。此外,还考虑了文献中发现的其他 33 种已知的 ELT 相关物质 (RS)。使用 Tanimoto/Jaccard 相似性搜索进行了分子相似性检查。建立了一组结构和拓扑相似的分子(包括 ELT 和 15 种 RS),并对其进行了体内毒性、吸收、分布、代谢和消除(ADME)预测。预测出的 RS 具有与 ELT 相似或更低的毒性和可比的 ADME 特征,并对其进行了分子对接,以追踪 TPO 受体亲和力的变化。结果表明,有五种 RS 与 ELT 的 Jaccard 相似度较高,对接得分也较高或相当。据预测,与 ELT 相比,这些化合物以及少量其他杂质的毒性更低,吸收、分布、代谢和排泄情况更好或相当。这就证明它们有可能成为药物研发中的新型 TPO 受体激动剂。

A cobalt-based metal–organic framework and graphene oxide were combined to prepare a new nanocomposite for extracting of caffeine from exhaled breath condensate (EBC) samples. Dispersive micro solid phase extraction of caffeine was conducted using the nanocomposite as a sorbent by adding 10 mg of it to the sample solution and vortexing for 3 min. After extracting of the analyte, it was eluted using the mobile phase. The analyte was then analyzed using high performance liquid chromatography-photodiode array detector. Under optimal conditions, the limit of detection, limit of quantification, and linear range of the calibration curve were found to be 1.7, 5.9, and 10–500 µg/L, respectively. To assess the precision of the method, five replicates of standard solutions containing caffeine at two different concentration levels (50 and 100 µg/L) were tested. The relative standard deviations for intra- and inter-day precisions ranged from 4.3 to 6.8 %. The applicability of the method was demonstrated by analyzing the samples obtained from premature infants undergoing caffeine treatment and caffeine concentrations were 4.9 ± 0.6, 2.7 ± 0.2 µg/L in the EBC samples of who were under treatment by a 5-mg dose. Also, caffeine concentrations were 5.9 ± 0.3 and 18 ± 0.6 µg/L in the the infants who obtained the 10-mg and 25-mg doses, respectively. The results indicated a satisfactory, extraction recovery of 86 % showcasing the method’s reliability and effectiveness in analyzing real samples.

Licorice, known as the “elder statesman,” is commonly used in traditional Chinese medicine (TCM) formulations. This study aims to establish a workflow combining animal and in silico experiments to elucidate the mechanisms of TCMs at both qualitative and quantitative levels. UPLC-Q-TOF-MS/MS was employed to qualitatively characterize the total components of honey-fried licorice and the plasma components after oral administration in Beagle dogs. A UPLC-Q-Trap-MS/MS method was developed for the pharmacokinetic study of honey-fried licorice components in Beagle dog plasma. Network pharmacology and molecular docking were utilized to explore the primary functional targets and pathways. In total, we identified 68 constituents in honey-fried licorice, with 28 detected in Beagle dog plasma, and 18 of them, mainly belong to flavonoids and terpenoids, showing significant exposure. The plasma pharmacokinetic study of these 18 constituents revealed that compounds like liquiritin, glycyrrhizic acid, licoricesaponin G2, and glycyrrhetic acid-3-o-glucuronide had significant exposure. Network pharmacology and molecular docking analyses identified MAPK3, PIK3CB, PIK3CA, RAF1, and EGFR as the main targets of the active constituents of honey-fried licorice, involved in pathways such as the Ras signaling pathway, human cytomegalovirus infection, and the MAPK signaling pathway. This study provides a comprehensive profile and pharmacokinetic characteristics of honey-fried licorice, offering insights into its pharmacological, toxicological, and clinical aspects. The established workflow can serve as a standard for investigating other TCMs.

The Cortex Juglandis Mandshuricae (CJM) has the efficacy of penetrating the liver meridian, removing heat and dampness, and alleviating the liver, which corresponds to the pathogenesis of alcoholic fatty liver disease (AFLD) with damp heat accumulation. Modern research has shown that total flavonoids from Cortex Juglandis Mandshuricae (TFC) have hepatoprotective, antioxidant and antitumour pharmacological effects. However, there is no any investigation on the mechanism of TFC improving AFLD. In this work, a valid strategy combining UPLC-Q-Exactive Orbitrap-MS, network pharmacology and in vitro cellular experimental validation is proposed to predict the targets and pathways of TFC to ameliorate AFLD and to explore its mechanism of action. As a result, 26 flavonoids and 182 targets linked to TFC and AFLD were identified. These compounds realize their critical targets via various signaling pathways and perform multiple biological functions on the basis of the constructed compound-disease target networks. In vitro experiments demonstrated TFC had a protective impact on ethanol-treated L02 cells to a certain extent and could diminished lipid accretion. In addition, RT-qPCR and western blot results illustrated that TFC could regulate the expression of PPARα, CPT-1, SREBP-1c and FAS, and inhibit alcohol-induced lipid accumulation in L02 cells thereby alleviating AFLD. The present study further provides experimental justification for TFC to ameliorate AFLD in practical applications.
黄精具有入肝经、清热利湿、疏肝理气的功效,与湿热蕴结型酒精性脂肪肝的发病机理相吻合。现代研究表明,毛果芸香科植物毛果芸香中的总黄酮具有保肝、抗氧化和抗肿瘤的药理作用。然而,目前尚未对 TFC 改善 AFLD 的机制进行任何研究。本研究提出了一种结合 UPLC-Q-Exactive Orbitrap-MS、网络药理学和体外细胞实验验证的有效策略,以预测 TFC 改善 AFLD 的靶点和途径,并探索其作用机制。结果发现了 26 种黄酮类化合物和 182 个与 TFC 和 AFLD 相关的靶点。在构建的化合物-疾病靶点网络基础上,这些化合物通过各种信号通路实现其关键靶点,并发挥多种生物学功能。体外实验表明,TFC对乙醇处理的L02细胞有一定程度的保护作用,并能减少脂质增生。此外,RT-qPCR和Western blot结果表明,TFC能调节PPARα、CPT-1、SREBP-1c和FAS的表达,抑制酒精诱导的L02细胞脂质蓄积,从而缓解AFLD。本研究进一步为 TFC 在实际应用中改善 AFLD 提供了实验依据。

Methylmalonic acid (MMA) is a reverse biomarker of vitamin B12 that is increasingly utilized in clinical practice. However, its low sensitivity and susceptibility to strong interference from isomer present chromatographic challenges. We have developed a rapid derivatization method for plasma MMA at room temperature, converting it to the corresponding 2,2,2-trifluoroethylamide derivative using N-(3-dimethylaminopropyl)-N’-ethylcarbodiimide hydrochloride (EDC) and 2,2,2-trifluoroethylamine hydrochloride (TFEA). Amidization was completed within 10 min, followed by protein precipitation extraction of the amides with trichloroacetic acid for Liquid chromatography-tandem mass spectrometry (LC-MS/MS) analysis. This technique notably enhanced the signal-to-noise ratio of MMA in chromatography. The derivatized MMA exhibited excellent linearity within a concentration range of 42.4–2711.9 nmol/L, with a correlation coefficient (R2) of 0.9990. The intraday and interday precision of replicate measurements ranged from 2.4 % to 4.4 % and 2.6 % to 2.8 %, respectively, while the recovery fell between 97.9 % and 100.1 %.
甲基丙二酸(MMA)是维生素 B12 的一种反向生物标记物,在临床实践中的应用越来越广泛。然而,甲基丙二酸的灵敏度低且易受异构体的强烈干扰,这给色谱分析带来了挑战。我们开发了一种室温下快速衍生血浆 MMA 的方法,利用 N-(3-二甲基氨基丙基)-N'-乙基碳二亚胺盐酸盐(EDC)和 2,2,2-三氟乙胺盐酸盐(TFEA)将其转化为相应的 2,2,2-三氟乙酰胺衍生物。酰胺化过程在 10 分钟内完成,然后用三氯乙酸对酰胺进行蛋白质沉淀萃取,再进行液相色谱-串联质谱(LC-MS/MS)分析。该技术显著提高了 MMA 在色谱分析中的信噪比。衍生化后的 MMA 在 42.4-2711.9 nmol/L 浓度范围内呈良好的线性关系,相关系数 (R2) 为 0.9990。重复测量的日内精密度和日间精密度分别为 2.4 % 至 4.4 % 和 2.6 % 至 2.8 %,回收率为 97.9 % 至 100.1 %。
