<div><div>Bioassay-guided fractionation led to the isolation of three new spirocyclic terpenoid compounds from <em>Euphorbia amygdaloides</em> L<em>.</em>, named Zagrosin I–III. Their structures were identified by 1D and 2D NMR (<sup>1</sup>H NMR, <sup>13</sup>C NMR, DEPT 135, HMBC, and HSQC-TOCSY) and LC-MS-MS spectrometry. The cytotoxicity of the isolated spirocyclic terpenoids (Zagrosin I-III) was assessed against human breast cancer (MCF-7), human fibrosarcoma (HT1080), and normal human foreskin fibroblast cells with MTT assays (24, 48, and 72 h treatments).

Enhanced oil recovery (EOR) remains paramount for tapping into residual oil post primary and secondary recovery stages. While conventional methods hold their ground, the rise of chemical EOR, especially utilizing nanofluids, stands out due to its economic viability, enhanced recovery efficiency, and adaptability. The allure of nanofluid-enhanced oil recovery (N-EOR) has grown amongst researchers, albeit with underlying mechanisms that still harbor inconsistencies and ambiguities. This review meticulously examines the micro-mechanics of nanofluid interactions with heavy oil molecules, particles, and surfaces, the methodologies underpinning nanofluid-assisted EOR, multiphase displacement within pores and cores, and the fluid–solid coupling during such flows. Key findings show that nanofluids alter mineral wettability, adjust oil/water interfacial tension, shift structural disjoining pressure, and curtail viscosity. The prowess of N-EOR largely hinges on nanoparticle adsorption. Their affinity for mineral surfaces induces a shift towards water-wet states, while their interplay at oil/water boundaries can tweak interfacial tensions, fostering emulsification. One standout revelation is the adsorption of asphaltenes on nanoparticles, which mitigates asphaltene concentrations in heavy oil, thereby diminishing viscosity and amplifying oil extraction. Contrary to previous studies that merely spotlighted outcomes, our review delves deep into the complexities of nanoparticle adsorption, spotlighting the harmonious interplay between nanoparticle adsorption features and N-EOR operations. We unravel the intricacies of nanofluid behaviors during multiphase core displacement and provide a detailed overview of pertinent simulations. To encapsulate, this study demystifies potential N-EOR techniques and charts fresh research trajectories. Our revelations aim to enrich the comprehension of N-EOR phenomena, accentuating the pivotal role of nanofluids in multiphase core transitions and computational simulations. Furthermore, we highlight lingering challenges, directing the scientific community towards continued nanoparticle innovations and exploration. The novelty of this study is as follows: Nanofluids are mainly used in the third oil recovery process, and are not used in the first and second oil recovery processes. In addition, during the third oil recovery, some nanofluids may remain in the mine due to the sedimentation characteristics of nanomaterials. Currently, we are also committed to developing new processes to reduce the deposition of nanomaterials in the mine. At present, it is not clear how nanofluids enhance the oil recovery mechanism, and the oil recovery mechanism is relatively chaotic. In this article, we analyzed these mechanisms.
提高石油采收率(EOR)对于开发一次和二次采油阶段后的剩余石油仍然至关重要。虽然传统方法仍有其优势,但化学 EOR(尤其是利用纳米流体)的兴起却因其经济可行性、更高的采油效率和适应性而脱颖而出。纳米流体提高石油采收率(N-EOR)的诱惑力在研究人员中与日俱增,尽管其基本机制仍存在不一致和模糊之处。本综述仔细研究了纳米流体与重油分子、颗粒和表面相互作用的微观力学、纳米流体辅助采油的基本方法、孔隙和岩心内的多相位移以及此类流动过程中的流固耦合。主要研究结果表明,纳米流体可改变矿物润湿性、调整油/水界面张力、改变结构分隔压力并降低粘度。N-EOR 的能力在很大程度上取决于纳米粒子的吸附力。纳米粒子对矿物表面的亲和力可诱导向水湿状态转变,而它们在油/水边界的相互作用可调整界面张力,促进乳化。一个突出的发现是沥青质在纳米颗粒上的吸附作用,它可以减轻重油中沥青质的浓度,从而降低粘度并提高石油提取率。与以往仅关注结果的研究不同,我们的综述深入探讨了纳米粒子吸附的复杂性,重点关注纳米粒子吸附特性与 N-EOR 操作之间的和谐互动。我们揭示了多相岩芯位移过程中纳米流体行为的复杂性,并提供了相关模拟的详细概述。总之,本研究揭开了潜在 N-EOR 技术的神秘面纱,并勾勒出新的研究轨迹。我们的发现旨在丰富对 N-EOR 现象的理解,强调纳米流体在多相堆芯转换和计算模拟中的关键作用。此外,我们还强调了仍然存在的挑战,引导科学界继续进行纳米粒子的创新和探索。本研究的新颖之处如下:纳米流体主要用于第三次采油过程,而不用于第一次和第二次采油过程。此外,在第三次采油过程中,由于纳米材料的沉积特性,一些纳米流体可能会残留在矿井中。目前,我们还致力于开发新的工艺,以减少纳米材料在矿井中的沉积。目前,纳米流体如何提高采油机理尚不清楚,采油机理也相对混乱。本文对这些机理进行了分析。

Zirconium-modified materials exhibit good adsorption performance, but their large-scale application is limited by the cost of carrier materials and the difficulty of solid–liquid separation of powder adsorbents. Therefore, in this study, we used low-cost gasification slag for zirconium oxide loading to avoid the aforementioned problems and successfully prepared a novel gasification slag–based zirconium-doped magnetic adsorbent material (GS-Z2M). GS-Z2M is a mesoporous adsorbent material with a large specific surface area (188 m2/g); it completely adsorbed phosphate with an initial concentration of 10 mg/L within 3 h. The rate-controlling step of phosphate removal using GS-Z2M was chemisorption. The Langmuir model proved more suitable for describing the adsorption of phosphate on GS-Z2M than the Freundlich and Temkin models, and the maximum phosphate adsorption capacity calculated using the Langmuir model was 26.02 mg/g. GS-Z2M showed good phosphate adsorption selectivity and reusability (can be recycled at least 5 times). GS-Z2M also showed good capacity for treating actual phosphate wastewater under dynamic flow conditions. The mechanism of phosphate adsorption on GS-Z2M mainly involved ligand exchange and inner-sphere complexation. The obtained results suggest that GS-Z2M is a promising adsorbent and vital for the development of phosphate adsorbents and recycling of gasification slag.
锆改性材料具有良好的吸附性能,但受载体材料成本和粉状吸附剂固液分离难度的限制,其大规模应用受到限制。因此,在本研究中,我们利用低成本的气化渣进行氧化锆负载,避免了上述问题,成功制备了一种新型的气化渣基掺锆磁性吸附材料(GS-Z2M)。GS-Z2M是一种介孔吸附材料,比表面积大(188 m2/g);初始浓度为10 mg/L时,GS-Z2M在3 h内完全吸附磷酸盐。化学吸附是GS-Z2M除磷的控制速率步骤。与Freundlich和Temkin模型相比,Langmuir模型更适合描述GS-Z2M对磷酸盐的吸附,使用Langmuir模型计算的最大磷酸盐吸附量为26.02 mg/g。GS-Z2M具有良好的磷酸盐吸附选择性和可重复使用性(可循环使用5次以上)。GS-Z2M在动态流动条件下也表现出较好的处理实际磷酸盐废水的能力。磷酸盐在GS-Z2M上的吸附机制主要包括配体交换和球内络合。结果表明,GS-Z2M是一种很有前途的吸附剂,对磷酸盐吸附剂的开发和气化渣的回收利用具有重要意义。

Epimedium total flavonoid capsules (ETFCs), a traditional Chinese patent medicine derived from Epimedium brevicornu Maxim., have been used for centuries to treat primary osteoporosis and are associated with kidney yang deficiency symptoms. Based on the “kidney-brain axis” hypothesis, previous study demonstrated that ETFCs can improve the cognitive function of MCAO rats, and the mechanism may involve the inflammatory response. However, little is known about their therapeutic components and scientific connotations. This study systematically investigates the anti-neuroinflammatory material basis and the mechanisms of ETFCs, integrating UPLC-Q/TOF-MS and UPLC-TQ-MS for chemical profiling, quantitative analysis of key components in rats′ plasma and brain, along with network pharmacology and activity verification. As a result, 65 components were identified. Metabolite profiling showed a total of 130 xenobiotics, highlighting the extensive metabolic transformations. Pharmacokinetic studies showed that primary flavonoid glycosides were quickly absorbed, while secondary glycosides exhibited slower absorption and elimination. In brain tissue, both prototype glycosides and secondary glycosides reached their peak concentrations rapidly, with Tmax between 0.25–1 h, while the prototype glycosides were eliminated after 8 h and secondary glycosides exhibited a secondary peak at 6–8 h. A network pharmacology study revealed that prototypes in blood may play a therapeutic role through targets including AKR1B1, PDE5A, and PTGS2 (COX-2). The LPS-induced BV-2 cell model confirmed ETFCs′ constituents showed inhibitory activities on pro-inflammatory cytokine secretion, mRNA expressions of IL-6, TNF-α, COX-2, iNOS and could down-regulate the protein expressions of COX-2 and iNOS. This research lays the foundation for the further development and utilization of ETFCs.
淫羊藿总黄酮胶囊(ETFCs)是从淫羊藿中提取的中成药。几个世纪以来一直用于治疗原发性骨质疏松症,并与肾阳虚症状有关。基于“肾脑轴”假说,已有研究证实etfc可改善MCAO大鼠的认知功能,其机制可能与炎症反应有关。然而,人们对它们的治疗成分和科学内涵知之甚少。本研究结合UPLC-Q/TOF-MS和UPLC-TQ-MS进行化学分析、大鼠血浆和脑内关键成分定量分析、网络药理学和活性验证,系统探讨etfc抗神经炎物质基础和作用机制。结果,确定了65个组成部分。代谢物分析显示总共有130种外源物,突出了广泛的代谢转化。药代动力学研究表明,黄酮类初级苷吸收快,次级苷吸收和消除慢。在脑组织中,原型苷和次级苷浓度均迅速达到峰值,Tmax在0.25-1 h之间,而原型苷在8 h后被消除,次级苷在6-8 h出现二次峰。一项网络药理学研究表明,血液中的原型可能通过包括AKR1B1、PDE5A和PTGS2 (COX-2)在内的靶点发挥治疗作用。lps诱导的BV-2细胞模型证实,etfc成分对促炎细胞因子分泌、IL-6、TNF-α、COX-2、iNOS mRNA表达均有抑制作用,并可下调COX-2、iNOS蛋白表达。本研究为etfc的进一步开发利用奠定了基础。

NQO1 is a FAD containing NAD(P)H-dependent oxidoreductase that catalyzes the reduction of quinones and related substrates, which plays an important role in the treatment of non-small cell lung cancer (NSCLC). Based on the indolequinone structure from 5-methoxy-2-methylindole, the indolequinone of NQO1 agonists was first coupled with amino-evodiamine derivatives by esterification reaction, and sixteen new compounds targeting NQO1 were developed. Among them, compounds 11b and 12d (IC50 = 2.72 or 3.66 µM, respectively) were showed better activity by cytotoxicity assay than the reference drug EVO (IC50 = 19.65 µM). Furthermore, the results of flow cytometry analysis showed that compounds 11b and 12d promoted apoptosis in A549 cells, blocked the cell cycle to the G2/M stage and caused a burst of reactive oxygen species. Western blotting experiments revealed that compounds 11b and 12d, after 24 h of treatment in A549 cells, downregulate the expression of Keap1 while upregulating the expression of Nrf2, NQO1, and HO-1. This suggests that compounds 11b and 12d increase cellular antioxidant capacity by regulating the Keap1/Nrf2/NQO1 antioxidant pathway. In vivo anti-tumor experiments showed that the reference drugs EVO (TGI = 15.94 %) and 5-Fu (TGI = 27.54 %) inhibited the proliferation of tumor tissue, while compound 11b could better inhibit the proliferation of tumor tissue (TGI = 39.13 %). In conclusion, our research results suggest that compounds 11b and 12d are potent agonism of the NQO1 signaling pathway and provide a potential opportunity to improve the treatment of NSCLC.
NQO1是一种含有NAD(P) h依赖性氧化还原酶的FAD,可催化醌类及相关底物的还原,在非小细胞肺癌(NSCLC)的治疗中发挥重要作用。基于5-甲氧基-2-甲基吲哚的吲哚醌结构,首次通过酯化反应将NQO1激动剂中的吲哚醌与氨基乙二胺衍生物偶联,共合成了16个靶向NQO1的新化合物。其中化合物11b和12d (IC50分别为2.72和3.66µM)的细胞毒活性优于对照药物EVO (IC50分别为19.65µM)。此外,流式细胞术分析结果显示,化合物11b和12d促进A549细胞凋亡,阻断细胞周期至G2/M期,引起活性氧爆发。Western blotting实验显示,化合物11b和12d在A549细胞中作用24 h后,下调Keap1的表达,上调Nrf2、NQO1和HO-1的表达。这表明化合物11b和12d通过调节Keap1/Nrf2/NQO1抗氧化途径提高细胞抗氧化能力。体内抗肿瘤实验表明,参比药物EVO (TGI = 15.94%)和5-Fu (TGI = 27.54%)对肿瘤组织的增殖有抑制作用,而化合物11b对肿瘤组织的增殖抑制作用更好(TGI = 39.13%)。总之,我们的研究结果表明,化合物11b和12d对NQO1信号通路具有强效激动作用,为改善非小细胞肺癌的治疗提供了潜在的机会。

Gentiana lawrencei var. farreri (GLF) is one of the varieties of the Tibetan medicinal herb “Bang Jian”, known as “Longdanhua” have been employed in Tibetan medicine for the treatment of inflammatory-related diseases. However, the anti-inflammatory effect of its play on the pharmacodynamic material and anti-inflammatory mechanism are still unclear. Therefore, in this study, we proposed UPLC-Q-TOF/MS combined with network pharmacology, molecular docking and in vitro experimental validation to explore the material basis and potential mechanism of the anti-inflammatory effect of GLF. Firstly, 43 compounds of GLF were identified by UPLC-Q-TOF/MS. Next, the potential 6 core active components, 15 core targets and 5 key pathways of GLF for the treatment of inflammation were used to predicted by network pharmacology. Then, molecular docking was used to validate the binding ability of core chemical constituents and core targets of GLF, and the results showed that the 6 core chemical constituents could bind well to 15 core targets, among which isoorientin had the lowest binding energy to AKT1 (−10.5 kcal mol−1). Finally, the promising anti-inflammatory activity of the key component isoorientin was verified by the LPS-induced macrophage inflammation model in RAW264.7 mice. This study revealed the anti-inflammatory pharmacodynamic material basis and mechanism of GLF, which provide a theoretical basis for the development, utilization, and clinical application of GLF.

The Quercus genus (oaks) comprises valuable plant resources that are used in many fields, including cosmetics, foods, and pharmaceuticals. Nonetheless, overall chemical profiling and anti-glycation component identification have not been thoroughly performed. In the present study, 70 % ethanolic and water extracts from three oak species (Quercus dentata, Q. serrata, and Q. aliena) showed antioxidant and anti-glycation potential. Thus, the components of the three oak species were profiled using ultra-performance liquid chromatography coupled with electrospray ionization and quadrupole time-of-flight mass spectrometry. The analysis showed that phenolic acids, ellagitannins, ellagic acid, procyanidin, and flavonoid (quercetin, myricetin, kaempferol, isorhamnetin, and taxifolin) glycosides are the main phenolic compounds. Based on the fluorescence assay, they act as strong inhibitors of non-enzymatic advanced glycation end-products (AGEs) formation in the bovine serum albumin (BSA) and skin proteins (collagen and elastin). Furthermore, mass fragmentation analysis demonstrated that ellagitannin, procyanidin B1 and flavonoid glycosides effectively trapped methylglyoxal (MGO), a reactive carbonyl intermediate and an important precursor of AGEs, to generate mono-, di-, or tri-MGO. Collectively, ellagic acid, ellagitannins, procyanidin B1, and flavonoid glycosides, the main active ingredients of three oak species (Q. dentata, Q. serrata, and Q. aliena), may be employed as lead structures in the development of functional foods or drugs to prevent diseases caused by aging and excessive sugar consumption.
栎属植物(橡树)拥有宝贵的植物资源,可用于化妆品、食品和药品等多个领域。然而,整体化学分析和抗糖化成分鉴定还没有彻底进行过。在本研究中,三种橡树(Quercus dentata、Q. serrata 和 Q. aliena)的 70% 乙醇提取物和水提取物显示出抗氧化和抗糖化的潜力。因此,使用超高效液相色谱法结合电喷雾离子化和四极杆飞行时间质谱法对这三种橡树的成分进行了分析。分析表明,酚酸、鞣花丹宁、鞣花酸、原花青素和黄酮(槲皮素、杨梅素、山奈醇、异鼠李素和紫杉醇)苷是主要的酚类化合物。根据荧光检测,它们是牛血清白蛋白(BSA)和皮肤蛋白质(胶原蛋白和弹性蛋白)中非酶高级糖化终产物(AGEs)形成的强力抑制剂。此外,质量碎片分析表明,鞣花单宁、原花青素 B1 和类黄酮苷能有效捕获甲基乙二醛(MGO)--一种活性羰基中间体和 AGEs 的重要前体--生成单-MGO、二-MGO 或三-MGO。鞣花酸、鞣花丹宁、原花青素 B1 和黄酮苷是三种橡树(Q. dentata、Q. serrata 和 Q.aliena)的主要活性成分,它们可以作为先导结构用于功能食品或药物的开发,以预防衰老和过量摄入糖分引起的疾病。

Background

Although still the significance of the lung-gut axis for COPD is increasingly highlighted, it’s urgent to ulteriorly comprehend the sophisticated disturbance of the core material system along the lung-gut axis, which is of great importance for the accurate precaution and prognosis of COPD efficiently.

Aim of the study

The purpose of this study was to analyze the information connections of the lung-gut axis, thus supporting the effective treatment of COPD.

Materials and methods

An integrated multi-omics approach was applied to explore the lung-gut axis in COPD rats. Firstly, based on transcriptomics, the ssGSEA algorithm was used to evaluate changes in pulmonary inflammatory cells. Then, the disturbances of metabolic pathways in lung and feces were revealed by the Lilikoi algorithm using LC-MS and 1H NMR metabolomics. Next, the composition and function of microbial communities in lung and feces were analyzed by 16 s rRNA sequencing. Finally, the association analysis was employed to explore the possible crosstalk between the lung and gut. Furthermore, the core material system in the lung-gut axis was described based on network topology analysis.

Result

Firstly, 1652 differential expression genes (involving in immune response-regulating signaling pathway, etc.) and 15 types of inflammatory cells (including neutrophil, etc.) were identified related to COPD. 135 pulmonary differential metabolites (involving in arachidonic acid metabolism, etc.) and 105 fecal differential metabolites (involving in alanine metabolism, etc.) were revealed by metabolomics. The f_Pasteurellaceae, etc. and g_Ruminococcus_2, etc. were identified associated with COPD in lung and gut. Finally, disturbances of the core material system, composed of macrophage, neutrophil, activated dendritic cell, myeloid derived suppressor cell, arachidonic acid metabolism, alpha linolenic acid & linoleic acid metabolism, g_Psychrobacter in lung and bile secretion, p_Proteobacteria in gut, were obtained to analyze the possible information flow of the lung-gut axis.

Conclusion

The core material system for the lung-gut axis have been revealed, which might contribute to the illustration of the pathogenesis of COPD. In the future, more researches are required on the impact of the core material system in the lung-gut axis on the onset and recovery process of COPD, suggesting more precise identifying effective treatments for the disease.
背景尽管肺-肠轴对慢性阻塞性肺疾病的意义仍日益凸显,但亟需进一步了解肺-肠轴核心物质系统的复杂紊乱,这对准确预防和有效预后慢性阻塞性肺疾病具有重要意义。研究目的本研究旨在分析肺-肠轴的信息联系,从而支持慢性阻塞性肺疾病的有效治疗。首先,基于转录组学,使用ssGSEA算法评估肺部炎症细胞的变化。然后,利用 LC-MS 和 1H NMR 代谢组学,通过 Lilikoi 算法揭示了肺和粪便中代谢途径的紊乱。接着,通过 16 s rRNA 测序分析了肺和粪便中微生物群落的组成和功能。最后,利用关联分析探讨了肺和肠道之间可能存在的串联。结果首先,确定了与慢性阻塞性肺病相关的 1652 个差异表达基因(涉及免疫反应调节信号通路等)和 15 种炎症细胞(包括中性粒细胞等)。代谢组学发现了 135 个肺部差异代谢物(涉及花生四烯酸代谢等)和 105 个粪便差异代谢物(涉及丙氨酸代谢等)。在肺部和肠道中发现了与慢性阻塞性肺病相关的 f_Pasteurellaceae 等和 g_Ruminococcus_2 等。最后,通过对由巨噬细胞、中性粒细胞、活化树突状细胞、髓样衍生抑制细胞、花生四烯酸代谢、α-亚麻酸代谢、亚油酸代谢、肺部 g_Psychrobacter 和胆汁分泌、肠道 p_Proteobacteria 等组成的核心物质系统的干扰,分析了肺-肠轴可能的信息流。今后,还需要进一步研究肺-肠轴核心物质系统对慢性阻塞性肺疾病发病和康复过程的影响,从而提出更精确、更有效的治疗方法。
