Abstract
Turmeric (Curcuma longa), a typical source with recognized anti-inflammatory activity, is one such medicine-food homology source, yet its anti-inflammatory mechanisms and specific component combinations remain unclear. In this study, a net fishing method combining bio-affinity ultrafiltration and ultra-high performance liquid chromatography-mass spectrometry (AUF-LC/MS) was employed and 13 potential COX-2 inhibitors were screened out from C. longa. 5 of them (C1, 17, 20, 22, 25) were accurately isolated and identified. Initially, their IC50 values were measured (IC50 of C1, 17, 20, 22 and 25 is 55.08, 48.26, 29.13, 111.28 and 150.48 μM, respectively), and their downregulation of COX-2 under safe concentrations (400, 40, 120, 50 and 400 μM for C1, 17, 20, 22 and 25, respectively) was confirmed on RAW 264.7 cells. Further, in transgenic zebrafish (Danio rerio), significant anti-inflammatory activity at safe concentrations (15, 3, 1.5, 1.5 and 3 μg/mL for C1, 17, 20, 22 and 25, respectively) were observed in a dose-dependent manner. More importantly, molecular docking analysis further revealed the mode of interaction between them and the key active site residues of COX-2. This study screened out and verified unreported COX-2 ligands, potentially accelerating the discovery of new bioactive compounds in other functional foods.

Huang Y, Chen Q, Pan W, Zhang Y, Li J, Xue X, Lei X, Wang S, Meng J. Moutan cortex exerts blood-activating and anti-inflammatory effects by regulating coagulation-inflammation cascades pathway in cells, rats and zebrafish. JOURNAL OF ETHNOPHARMACOLOGY 2024; 320:117398. [PMID: 37981122 DOI: 10.1016/j.jep.2023.117398] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/17/2023] [Revised: 11/03/2023] [Accepted: 11/06/2023] [Indexed: 11/21/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE As a traditional Chinese medicine, raw Moutan Cortex (RMC) has been used in clinical practice for thousands of years. However, its blood-cooling and blood-activating medicinal effects as well as the underlying mechanisms have not been preliminarily verified until recent years. AIM OF THE STUDY Our group's previous network pharmacological studies suggested that RMC might exert its blood-activating and anti-inflammatory effects by modulating the coagulation-inflammation cascade pathway. Therefore, the present study aimed to further investigate the mechanisms relevant to the blood-activating and anti-inflammatory effects of RMC so as to provide more robust data supporting its clinical application. MATERIALS AND METHODS The inflammation and coagulation models of human umbilical vein endothelial cells (HUVECs) were induced by TNF-α; The rat models with blood-heat and blood-stasis syndrome (BHS) were constructed by ice-water bath with a combined use of epinephrine hydrochloride and dried yeast; The thrombus models of zebrafish were induced by arachidonic acid, and the inflammation models were established using LPS and CuSO4. The regulatory effects of RMC on the key targets in the pathway of the coagulation-inflammation cascade were investigated by combining ELISA, RT-PCR, and western blot techniques in an attempt to provide multiple validations concerning RMC's pharmacological efficacy and mechanism associated with cooling blood and activating blood circulation. RESULT The findings from the pharmacodynamic research demonstrated that RMC could inhibit the coagulation and inflammation process of HUVECs. Besides, it lowered the anal temperature and whole blood viscosity in BHS rats in addition to a prolongation of their prothrombin time (PT), thrombin time (TT), and activated partial thromboplastin time (APTT). Successfully constrained thrombotic area and reduced inflammatory cell counts were also observed in zebrafish models. Meanwhile, ELISA, RT-PCR and WB showed that RMC were capable of inhibiting the factors related to coagulation-MARK inflammation pathway-FⅡ, TF, FⅦ, FⅧ, FⅩ, and PAI, as well as down-regulating the expression of IL-6, COX-2, iNOS, TNF-α, ERK, JNK and p38. CONCLUSION RMC exerts blood-activating and anti-inflammatory effects through regulating the target genes of the coagulation-MARK inflammation cascade pathway.

Molecules 2024; 29:806. [PMID: 38398558 PMCID: PMC10892563 DOI: 10.3390/molecules29040806] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/08/2024] [Revised: 02/04/2024] [Accepted: 02/06/2024] [Indexed: 02/25/2024] Open
Abstract
Millettia speciosa Champ. (MSCP) enjoys widespread recognition for its culinary and medicinal attributes. Despite the extensive history of MSCP cultivation, the disparities in quality and bioactivity between wild and cultivated varieties have remained unexplored. In this study, 20 wild and cultivated MSCP samples were collected from different regions in China. We embarked on a comprehensive investigation of the chemical constituents found in both wild and cultivated MSCP utilizing UHPLC-Q-Exactive Orbitrap-MS technology and multivariate analysis such as principal component analysis (PCA) and orthogonal partial least squares discriminant analysis (OPLS-DA). In total, 62 chemical components were unequivocally identified or tentatively characterized. Via the multivariate statistical analysis, we successfully pinpointed nine compounds with the potential to serve as chemical markers, enabling the differentiation between wild and cultivated MSCP varieties. Moreover, both genotypes exhibited substantial antioxidant and anti-fatigue properties. The bioactivities of wild MSCP were marginally higher when compared to their cultivated counterparts. This study illuminates the impressive antioxidant and anti-fatigue potential present in both wild and cultivated MSCP genotypes, further augmenting the allure of this species and opening new avenues for the economic valorization of MSCP. Hence, this study provides a valuable method for the identification and quality control of MSCP and a method in chemistry and pharmacology to assess an alternative possibility for cultivated MSCP.

Identification of potential anti-inflammatory components in Moutan Cortex by bio-affinity ultrafiltration coupled with ultra-performance liquid chromatography mass spectrometry. Front Pharmacol 2024; 15:1358640. [PMID: 38384290 PMCID: PMC10880116 DOI: 10.3389/fphar.2024.1358640] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/20/2023] [Accepted: 01/15/2024] [Indexed: 02/23/2024] Open
Abstract
Moutan Cortex (MC) has been used in treating inflammation-associated diseases and conditions in China and other Southeast Asian countries. However, the active components of its anti-inflammatory effect are still unclear. The study aimed to screen and identify potential cyclooxygenase-2 (COX-2) inhibitors in MC extract. The effect of MC on COX-2 was determined in vitro by COX-2 inhibitory assays, followed by bio-affinity ultrafiltration in combination with ultra-performance liquid chromatography-mass spectrometry (BAUF-UPLC-MS). To verify the reliability of the constructed approach, celecoxib was applied as the positive control, in contrast to adenosine which served as the negative control in this study. The bioactivity of the MC components was validated in vitro by COX-2 inhibitor assay and RAW264.7 cells. Their in vivo anti-inflammatory activity was also evaluated using LPS-induced zebrafish inflammation models. Finally, molecular docking was hired to further explore the internal interactions between the components and COX-2 residues. The MC extract showed an evident COX-2-inhibitory effect in a concentration-dependent manner. A total of 11 potential COX-2 inhibitors were eventually identified in MC extract. The COX-2 inhibitory activity of five components, namely, gallic acid (GA), methyl gallate (MG), galloylpaeoniflorin (GP), 1,2,3,6-Tetra-O-galloyl-β-D-glucose (TGG), and 1,2,3,4,6-Penta-O-galloyl-β-D-glucopyranose (PGG), were validated through both in vitro assays and experiments using zebrafish models. Besides, the molecular docking analysis revealed that the potential inhibitors in MC could effectively inhibit COX-2 by interacting with specific residues, similar to the mechanism of action exhibited by celecoxib. In conclusion, BAUF-UPLC-MS combining the molecular docking is an efficient approach to discover enzyme inhibitors from traditional herbs and understand the mechanism of action.

Abstract
Traditional Chinese medicine is the main source of natural products due to its remarkable clinical efficacy. Syringa oblata Lindl (S. oblata) was widely used because of its extensive biological activities. However, to explore the antioxidant components of S. oblata against tyrosinase, the experiments of antioxidation in vitro were employed. At the same time, the determination of TPC was also use to assess the antioxidant ability of CE, MC, EA and WA fractions and the liver protective activity of the EA fraction was evaluated by mice in vivo. Next, UF-LC-MS technology was performed to screen and identify the efficient tyrosinase inhibitors in S. oblata. The results showed that alashinol (G), dihydrocubebin, syripinin E and secoisolariciresinol were characterized as potential tyrosinase ligands and their RBA values were 2.35, 1.97, 1.91 and 1.61, respectively. Moreover, these four ligands can effectively dock with tyrosinase molecules, with binding energies (BEs) ranging from 0.74 to -0.73 kcal/mol. In addition, tyrosinase inhibition experiment was employed to evaluate the tyrosinase inhibition activities of four potential ligands, the result showed that compound 12 (alashinol G, IC50 = 0.91 ± 0.20 mM) showed the strongest activity to tyrosinase, followed by secoisolariciresinol (IC50 = 0.99 ± 0.07 mM), dihydrocubebin (IC50 = 1.04 ± 0.30 mM) and syripinin E (IC50 = 1.28 ± 0.23 mM), respectively. The results demonstrate that S. oblata might have excellent antioxidant activity, and UF-LC-MS technique is a effective means to filter out tyrosinase inhibitors from natural products.

Abstract
Traditional Chinese medicine is a rich source of natural products and has a long history of use because of its remarkable clinical efficacy. In the present study, the chemical constitutes of Angelica pubescens were studied by ultra high performance liquid chromatography and high-resolution Orbitrap mass spectrometry (UPLC-HR-Orbitrap-MS). A total of 78 compounds were identified and the main composition were coumarins and phenolic acids. Then, the neuraminidase was incubated with extract of Angelica pubescens to screen the neuraminidase inhibitors by affinity ultrafiltration methods. As a result, 13 small molecules were discovered to interact with neuraminidase for the first time. In vitro neuraminidase inhibitory activity of the screened compounds and extract of Angelica pubescens was tested, and isochlorogenic acid C, isochlorogenic acid B, osthole, chlorogenic acid, xanthotoxin, phellopterin and imperatorin were proved to have this activity. In addition, molecular docking analysis was conducted to predict the potential docking position. This study may provide a reference for the medical substance basis in Angelica and the clinical usage of this drug.
