Background:: Metabolic syndrome (MetS), also known as syndrome X or insulin resistance, is a complex disorder characterized by multiple risk factors. It is caused by insulin resistance, which is accompanied by abnormal accumulation and dysfunction of adipose tissue. Introduction:: Recently, several studies have evaluated the efficacy of herbs on MetS. The purpose of this meta-analysis is the comprehensive assessment of the impact of cardamom, cinnamon, saffron, purslane and ginger on the parameters of MetS in patients with MetS. Methods:: A systematic search was performed based on the English language reports of literature from databases including PubMed, Scopus, Cochrane, and Web of Science and 29 RCT (randomized clinical trial) studies were included in the meta-analysis. This meta-analysis was registered in PROSPERO. Results:: The results showed significant beneficial effects of cardamom on Homeostatic Model Assessment for Insulin Resistance (HOMA-IR) and waist circumference (WC), cinnamon on diastolic blood pressure (DBP) and weight, ginger on fasting blood sugar (FBS), Hemoglobin A1c HbA1c and HOMA-IR and purslane on triglyceride (TG), total cholesterol (TC), body mass index (BMI) and FBS compared to the placebo; thus, they can be useful in the management of patients with MetS. Conclusion:: It is suggested that more RCT studies should be performed on the factors affecting the efficacy of these plants on the parameters of the MetS.

Introduction:: Breast cancer is one of the most prevalent malignancies among women around the world. Crocus sativus, a natural food coloring and flavoring, has potent anti-tumor properties. The aim of the current study was to investigate the therapeutic potential of crocin, the main pharmacological active component of saffron, either alone or in combination with the standard chemotherapeutic treatment, 5-FU, in Breast cancer (BC) progression in both cellular and animal models. Material and Methods: MTT, Real-Time PCR, Western Blotting, Hematoxylin and eosin (H&E) tissue staining were applied to determine the anti-tumor properties of crocin in in vitro and in vivo samples. Results:: Our findings showed that crocin decreased breast cancer cell proliferation by suppressing cyclin D1 expression and Wnt/β-catenin signaling activation. Moreover, this molecule improved 5- FU anti-cancer activities by decreasing the tumor volume and weight, increasing tumor necrosis, and suppressing tumor inflammation in an animal model. Inflammation-associated anti-cancer activity of crocin is mediated by the down-regulation of pro-inflammatory genes, including IFN-γ and IL-1β, as well as inhibition of oxidative stress responses within the tumor environment. Conclusion:: This is the first study demonstrating the potent anti-tumor properties of crocin against BC progression. Our results suggest that this effective and low-toxic molecule could be a promising agent for reducing BC tumor progression when administered either alone or in combination with standard treatment in breast cancer patients.
导言乳腺癌是全世界妇女最常见的恶性肿瘤之一。藏红花是一种天然食用色素和香料,具有强大的抗肿瘤特性。本研究旨在探讨藏红花的主要药理活性成分藏红花素单独或与标准化疗药物 5-FU 联合使用对乳腺癌(BC)细胞和动物模型进展的治疗潜力。材料与方法应用 MTT、Real-Time PCR、Western 印迹、血氧菌素和伊红(H&E)组织染色法确定藏红花苷在体外和体内样本中的抗肿瘤特性。结果我们的研究结果表明,巴豆素能抑制细胞周期蛋白 D1 的表达和 Wnt/β-catenin 信号的激活,从而减少乳腺癌细胞的增殖。此外,在动物模型中,该分子通过减少肿瘤体积和重量、增加肿瘤坏死和抑制肿瘤炎症,提高了 5- FU 抗癌活性。炎症相关的黄花苷抗癌活性是通过下调促炎症基因(包括 IFN-γ 和 IL-1β)以及抑制肿瘤环境中的氧化应激反应来介导的。结论这是第一项证明巴豆苷能有效抗肿瘤的研究。我们的研究结果表明,这种有效且低毒的分子在单独给药或与乳腺癌患者的标准治疗联合使用时,可能是一种很有前途的减少乳腺癌肿瘤进展的药物。

IF 1 4区 医学 Q4 CHEMISTRY, MEDICINAL Pub Date : 2024-01-21 DOI: 10.2174/0115701808277988240105083347

Background: The increasing incidence of hyperlipidemia (HLP) is attributed to the imbalance in redox homeostasis, aberrant lipid metabolism, and the excessive intake of empty calories. Dajihan Pill (DJHP) is a Traditional Chinese Medicine (TCM) formula composed of Zingiberis Rhizoma (ZR), Piperis Longi Fructus (PLF), Alpiniae Officinarum Rhizome (AOR), and Cinnamomi Cortex (CC) in a ratio of 3:2:3:2. It exhibits a significant preventive effect on HLP. Certainly, the active components and the precise mechanism of action are not fully understood. Therefore, this study aims to elucidate the preventive and ameliorative mechanisms of DJHP against HLP by integrating network pharmacology, molecular docking, and experimental validation. Method: Based on the pharmacological method, active ingredients in DJHP and targets were extracted from Traditional Chinese Medicine System Pharmacology (TCMSP) and UniProt. Then core compounds and targets were obtained by constructing “compounds-targets-disease” and proteinprotein interaction (PPI) network. Gene Ontology (GO) function analysis and Kyoto Encyclopedia of Genes and Genomes (KEGG) were employed to elucidate further the associated action mechanism. The molecular binding mechanisms between the core ingredients and targets were elucidated through molecular docking. Additionally, the antioxidant capacities of DJHP extracts were investigated by assessing their DPPH, hydroxyl, and ABTS radical scavenging activities. Results: A total of 45 active compounds and 258 targets were identified in DJHP. Network analysis indicated that quercetin, beta-sitosterol, kaempferol, and oleic acid might serve as core bioactive compounds. Seven core targets, including AKT1, INS, and TNF, were identified as potential preventive targets. GO analysis suggested the improvement of HLP by DJHP may be related to the lipid metabolic process, high-density lipoprotein particle, triglyceride binding, and inflammatory response. The KEGG analysis indicated TNF, HIF-1, and AMPK signaling pathways were involved. The observations of active compounds binding with core targets indicated an excellent combination. Additionally, antioxidant results showed that DJHP exhibited significant DPPH, hydroxyl, and ABTS radical scavenging activities. Conclusion: Theoretical and experimental investigations indicate that DJHP can effectively modulate various signaling pathways and enhance the redox system, thus mitigating HLP. Our work provided a basis for the pharmacological study of DJHP in preventing HLP and further research.
背景:高脂血症(HLP)的发病率越来越高,其原因是氧化还原平衡失调、脂质代谢异常和空热量摄入过多。大吉漢丸(DJHP)是一種中藥配方,由薑科植物薑(Zingiberis Rhizoma,ZR)、荜茇(Piperis Longi Fructus,PLF)、白花蛇舌草(Alpiniae Officinarum Rhizome,AOR)和肉桂(Cinnamomi Cortex,CC)按 3:2:3:2 的比例配製而成。它对 HLP 有明显的预防作用。当然,其活性成分和确切的作用机制尚未完全清楚。因此,本研究旨在通过整合网络药理学、分子对接和实验验证,阐明DJHP对HLP的预防和改善机制。研究方法根据药理学方法,从中药系统药理学(TCMSP)和UniProt中提取DJHP中的有效成分和靶点。然后通过构建 "化合物-靶标-疾病 "和蛋白质相互作用(PPI)网络获得核心化合物和靶标。利用基因本体(GO)功能分析和京都基因组百科全书(KEGG)进一步阐明了相关的作用机制。通过分子对接,阐明了核心成分与靶标之间的分子结合机制。此外,通过评估DPPH、羟基和ABTS自由基清除活性,研究了DJHP提取物的抗氧化能力。研究结果在 DJHP 中共鉴定出 45 种活性化合物和 258 个靶标。网络分析表明,槲皮素、β-谷甾醇、山柰醇和油酸可能是核心生物活性化合物。包括 AKT1、INS 和 TNF 在内的七个核心靶点被确定为潜在的预防性靶点。GO分析表明,DJHP对HLP的改善可能与脂质代谢过程、高密度脂蛋白颗粒、甘油三酯结合和炎症反应有关。KEGG 分析表明 TNF、HIF-1 和 AMPK 信号通路参与其中。通过观察活性化合物与核心靶点的结合情况,可以发现这是一种很好的组合。此外,抗氧化结果表明,DJHP 具有显著的 DPPH、羟基和 ABTS 自由基清除活性。结论理论和实验研究表明,DJHP 可有效调节各种信号通路,增强氧化还原系统,从而缓解 HLP。我们的工作为 DJHP 预防 HLP 的药理研究和进一步研究提供了基础。

Aims:: Synthesis of novel 4-bromobenzoic acid-based hydrazone-Schiff base derivatives and to screen them for their α-amylase inhibitory activity. Objective:: The biological activities of hydrazone-Schiff base compounds encouraged us to evaluate the synthesized derivatives (4-32) for in-vitro inhibition activity against the α-amylase enzyme. Methods:: In current research work twenty-nine Schiff base derivatives (4-32) of 4-bromobenzoic acid were synthesized in worthy yields by treating various replaced aldehydes with 4- bromobenzohydrazide using methanol solvent in catalytic quantity of acetic acid. The products were structurally described through the support of several spectroscopic methods (EI-MS and 1HNMR) and finally evaluated against α-amylase enzyme. Results:: All the made derivatives exhibited worthy inhibition potential from IC50 = 0.21 ± 0.01 to 5.50 ± 0.01 μM when equated to the usual acarbose drug having IC50 = 1.34 ± 0.01 μM. Compound 21 (IC50 = 0.21 ± 0.01 μM) was established as the most active inhibitor among the series better than standard. The structure-activity relationship study showed that the alteration in the activity of the produced products might be due to the attached position and nature of the substituents. Furthermore, in-silico study supported the effects of groups attached on the binding interaction with α-amylase enzyme. Conclusion:: A series of substituted hydrazone Schiff bases based on 4-bromobenzoic acid were produced, confirmed the structures by EI-MS and 1H-NMR spectroscopic methods and lastly tested for their in-vitro α-amylase inhibitory potential. Among the series, twenty-four products indicated brilliant inhibition potential having IC50 values from 0.21 ± 0.01 to 1.30 ± 0.01 μM. The structure-activity relationship study showed that the alteration in the activity of the synthesized products might be due to the attached position and nature of the substituents. On the other hand, in silico studies advocated that the synthesized Schiff base derivatives have prevalent interactions of binding within the active site of the α-amylase enzyme, and because of their various attached substituent, their conformation is altered in the active site of the enzyme. The current study recognized a number of lead candidates derived from 4-bromobenzoic acid. Additional investigation of the synthesized derivatives for coming research to get novel α-amylase inhibitors.
目的::合成新型 4-溴苯甲酸肼基希夫碱衍生物,并筛选其对α-淀粉酶的抑制活性。目的::肼基-希夫碱化合物的生物活性促使我们对合成的衍生物(4-32)进行体外α-淀粉酶抑制活性评估。研究方法在目前的研究工作中,我们使用甲醇溶剂和催化量的乙酸,通过用 4-溴苯甲酰肼处理各种被取代的醛,合成了 29 种 4-溴苯甲酰肼希夫碱衍生物(4-32)。通过几种光谱方法(EI-MS 和 1HNMR)对产物进行了结构描述,最后对α-淀粉酶进行了评估。结果与通常阿卡波糖药物(IC50 = 1.34 ± 0.01 μM)相比,所有制成的衍生物都表现出了很高的抑制潜力,IC50 = 0.21 ± 0.01 至 5.50 ± 0.01 μM。化合物 21(IC50 = 0.21 ± 0.01 μM)被确定为该系列中最有效的抑制剂,其效果优于标准抑制剂。结构-活性关系研究表明,生成物活性的改变可能与取代基的连接位置和性质有关。此外,硅内研究也证实了所附基团对与α-淀粉酶结合相互作用的影响。结论制备了一系列基于 4-溴苯甲酸的取代腙席夫碱,并通过 EI-MS 和 1H-NMR 光谱方法确认了其结构,最后对其体外α-淀粉酶抑制潜力进行了测试。在这一系列中,有 24 种产品具有出色的抑制潜力,其 IC50 值在 0.21 ± 0.01 至 1.30 ± 0.01 μM 之间。结构-活性关系研究表明,合成产物活性的改变可能与取代基的连接位置和性质有关。另一方面,硅学研究表明,合成的席夫碱衍生物在α-淀粉酶的活性位点内具有普遍的结合相互作用,并且由于其所附取代基的不同,它们在酶活性位点内的构象发生了改变。目前的研究发现了一些由 4-溴苯甲酸衍生的候选先导化合物。今后将对合成的衍生物进行进一步研究,以获得新型的α-淀粉酶抑制剂。

Background: Nitric oxide (NO), an important second messenger molecule, regulates numerous physiological responses, while excessive NO generates negative effects on the circulatory, nervous and immune systems. Recently, some natural flavonoids were reported to possess the capability of inhibiting LPS-induced NO production. To fully understand the nature of their own NO inhibitory activity, it is necessary to address the structural requirements of flavonoids as NO inhibitors. Objective: The objective of this work was to develop efficient QSAR models for predicting the NOinhibitory activity of new flavonoids and improving insights into the critical properties of the chemical structures that were required for the ideal NO production inhibitory activities. Methods: To provide insights into the structural basis of flavonoids as NO inhibitors, 3D quantitative structure-activity relationship (3D-QSAR) and 2D-QSAR models were developed on a dataset of 55 flavonoids using comparative molecular field analysis (CoMFA), comparative molecular similarity indices analysis (CoMSIA) and hologram quantitative structure-activity relationship (HQSAR) approaches. method: CoMFA, CoMSIA combining HQSAR methods were employed on a series of flavonoids to generate 3D and 2D-QSAR models. Results: The statistically significant models for CoMFA, CoMSIA and HQSAR resulted in crossvalidated coefficient (q2) values of 0.523, 0.572 and 0.639, non-cross-validated coefficient (r2) values of 0.793, 0.828 and 0.852, respectively. The robustness of these models was further affirmed using a test set of 18 compounds, which resulted in predictive correlation coefficients (r2 pred) of 0.968, 0.954 and 0.906. Furthermore, the models-derived contour maps were appraised for activity trends for the molecules analyzed. result: Comparative Molecular Field Analysis (CoMFA), Comparative Molecular Similarity Indices Analysis (CoMSIA) combining hologram quantitative structure-activity relationship (HQSAR) methods were employed on a series of flavonoids to generate 3D and 2D-QSAR models. Result: The obtained models can be used to predict the activities of new flavonoids and identify the key structural features affecting the NO inhibitory activities. Conclusion: The 3D and 2D-QSAR models constructed in this paper were efficient in estimating the NO inhibitory activities of flavonoids and facilitating the design of flavonoid-derived NO production inhibitors. other: none

Background: In recent years, as the biological activity of the quinoxaline skeleton has been revealed in numerous studies, interest in synthesizing new prototype molecules for the treatment of many chronic diseases, especially cancer, has increased. Methods: The desired alkoxy substituted aminoquinoxalines (AQNX1-9) were synthesized by the reaction of QNX and alkoxy substituted aryl amines such as 2-methoxyaniline, 4-methoxyaniline, 2- ethoxyaniline, 3-ethoxyaniline, 4-ethoxyaniline, 4-butoxyaniline, 2,4-dimethoxyaniline, 3,4- dimethoxyaniline, and 3,5-dimethoxyaniline according to the previously published procedure. QNX was aminated in DMSO at 130°C. We synthesized various alkoxy-substituted aminoquinoxaline compounds (AQNX1-9) and evaluated their anticancer and antimicrobial activities in order to expand the search to related structures. In particular, two aminoquinoxaline (AQNX5 and AQNX6) compounds, coded as NSC D-835971/1 and NSC D-835972/1 by the National Cancer Institute in the USA, were screened for anticancer screening at a dose of 10-5 M on a full panel of 60 human cell lines obtained from nine human cancer cell types (leukemia, melanoma, non-small cell lung, colon, central (nervous system, ovarian, kidney, prostate, and breast cancer). objective: Therefore, we synthesized various alkoxy-substituted aminoquinoxaline compounds (AQNX1-9) and evaluated their anticancer and antimicrobial activities in order to expand the search to related structures. Results: Further in silico studies were also conducted for the compound AQNX5 (NSC D- 835971/1), which was found to be the most active antiproliferative agent, especially against leukemia cell lines. Molecular docking studies showed that AQNX5 interacted with Glu286 and Lys271 through hydrogen bonding and π-stacking interaction in the ATP binding region of Abl kinase, which is indicated as a potential target of leukemia. Besides, AQNX5 occupied the minor groove of the double helix of DNA via π-stacking interaction with DG-6. method: Especially, the two aminoquinoxalines (AQNX5 and AQNX6) with the NCI codes NSC D-835971/1 and NSC D-835972/1 selected by NCI, USA, were screened for anticancer screening at a 10-5 M dose in the full panel of 60 human cell lines derived from nine human cancer cell types (leukemia, melanoma, non-small-cell lung, colon, central nervous system, ovarian, renal, prostate, and breast cancer) at the NIH, Bethesda, Maryland, USA. Conclusion: According to in silico pharmacokinetic determination, AQNX5 was endowed with drug-like properties as a potential anticancer drug candidate for future experiments. In the light of these findings, more research will focus on aminated quinoxalines' ability to precisely target leukemia cancer cell lines. conclusion: In the light of these findings, more research will focus on aminated quinoxalines' ability to precisely target leukemia cancer cell lines.

Background:: CDK4/6 plays a crucial role in regulating cell proliferation, and inhibiting this kinase can effectively prevent the initiation of cell growth and division. However, current FDAapproved CDK4/6 inhibitors have limitations such as poor bioavailability, adverse effects, high cost, and limited accessibility. Thus, this research aimed to discover novel CDK4/6 inhibitors to overcome the challenges associated with FDA-approved inhibitors. Methods:: To identify potential CDK4/6 inhibitors, we have performed structure-based virtual screening. Chem-space and Mcule databases have been screened, followed by a series of filtering steps. These steps included assessing drug-likeness, PAINS alert, synthetic accessibility scores, ADMET properties, consensus molecular docking, and performing molecular dynamics simulations. Results:: Four new compounds (CSC089414133, CSC091186116, CSC096023304, CSC101755872) have been identified as potential CDK4/6 inhibitors. These compounds exhibited strong binding affinity with CDK4/6, possessed drug-like features, showed no PAINS alert, had a low synthetic accessibility score, demonstrated effective ADMET properties, were non-toxic, and exhibited high stability. Conclusion:: Inhibiting CDK4/6 with the identified compounds may lead to reduced cell proliferation and the promotion of cancer cell death. result: Four compounds (CSC089414133, CSC091186116, CSC096023304, CSC101755872) were identified as potential CDK4/6 inhibitors.

Background: Conformational changes in BAX are associated with the activation of its pro-apoptotic potential. Previously, small molecule BAX antagonists have been shown to bring about apoptosis by inducing conformational changes in BAX by direct binding to the serine 184 site of BAX. Methods: In this article, we have proposed that syringic acid analog SA14 can incur apoptosis by directly binding to and inducing conformational changes in BAX. The pro-apoptotic potential of SA14 has been investigated using an in silico structure-based approach, i.e., docking and molecular dynamics computations are employed to study the binding of SA14 to the residues of the active site of BAX. Results: Based on docking results, four BAX-SA14 complexes, each representative of a cluster of conformations, have been selected for molecular dynamics simulations. The root mean square deviation has indicated the formation of stable conformations for two of the complexes. Other parameters, such as root mean square fluctuation, radius of gyration, and solvent accessible surface area, have been used to confirm the results, which have indicated favorable binding between BAX and SA14. Conclusion: Overall, the results have indicated that SA14 can bring about stable conformational changes in BAX and shows merit as a potential BAX-activating pro-apoptotic agent worthy of further experimental studies.
背景:BAX 的构象变化与其促凋亡潜能的激活有关。此前,小分子 BAX 拮抗剂通过直接与 BAX 的丝氨酸 184 位点结合,诱导 BAX 发生构象变化,从而导致细胞凋亡。方法:在本文中,我们提出丁香酸类似物 SA14 可通过直接与 BAX 结合并诱导其构象变化而导致细胞凋亡。我们采用了一种基于硅学结构的方法来研究 SA14 的促凋亡潜力,即利用对接和分子动力学计算来研究 SA14 与 BAX 活性位点残基的结合。研究结果根据对接结果,选择了四种 BAX-SA14 复合物进行分子动力学模拟。均方根偏差表明其中两个复合物形成了稳定的构象。其他参数,如均方根波动、回转半径和溶剂可接触表面积,也被用来证实结果,这些参数表明 BAX 与 SA14 之间的结合是有利的。结论总之,研究结果表明 SA14 能使 BAX 发生稳定的构象变化,是一种潜在的 BAX 激活促凋亡剂,值得进一步实验研究。

Background: Pre-eclampsia (PE) is a pregnancy-related complication that has a global prevalence of 3-5% among pregnant women. Objective: The objective of this study is to examine the molecular mechanism underlying the therapeutic effects of Astragalus membranaceus (AE) in the treatment of PE through the application of network pharmacology and molecular docking. Methods: The databases, including TCMSP, Uniprot, Genecards, STRING, and DAVID, and software, including jvenn, Cytoscape, and AutoDock Vina, were used to do the analysis. Results: Sixteen AE-related active ingredients were screened, involving 127 targets, among which the main active ingredients included kaempferol, quercetin, and jaranol, etc. The primary targets of AE for the management of PE encompassed AKT1, CASP3, EGFR, IL1B, IL6, MMP9, PTGS2, TNF, TP53, and VEGFA. The outcomes of the enrichment analysis revealed that AE was predominantly implicated in pathways such as the IL-17 signaling pathway and PI3K-Akt signaling pathway, among others. The molecular docking findings confirmed that the principal active constituents exhibit favorable binding to their central targets. Specifically, the molecular docking results evinced that the primary active ingredients evince robust binding activity towards the core targets. Conclusion: AE has the potential to act synergistically in the management of PE by engaging multiple components, targets, and pathways, thereby establishing a basis for further exploration of its material basis and mechanism of action.
背景:子痫前期(PE)是一种与妊娠有关的并发症,在全球孕妇中的发病率为 3-5%。研究目的本研究旨在通过应用网络药理学和分子对接研究黄芪治疗子痫前期的分子机制。研究方法使用 TCMSP、Uniprot、Genecards、STRING 和 DAVID 等数据库和 jvenn、Cytoscape 和 AutoDock Vina 等软件进行分析。结果筛选出 16 种与 AE 相关的活性成分,涉及 127 个靶点,其中主要活性成分包括山奈酚、槲皮素、山奈醇等。AE 治疗 PE 的主要靶点包括 AKT1、CASP3、表皮生长因子受体、IL1B、IL6、MMP9、PTGS2、TNF、TP53 和 VEGFA。富集分析结果表明,AE 主要与 IL-17 信号通路和 PI3K-Akt 信号通路等通路有关。分子对接结果证实,主要活性成分与其中心靶标的结合良好。具体来说,分子对接结果表明,主要活性成分与核心靶点具有很强的结合活性。结论AE 有可能通过与多种成分、靶点和途径的结合,在 PE 的治疗中发挥协同作用,从而为进一步探索其物质基础和作用机制奠定基础。
