[PMID: 38909829 DOI: 10.1016/j.jep.2024.118470] [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: 03/10/2024] [Revised: 06/14/2024] [Accepted: 06/17/2024] [Indexed: 06/25/2024]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Initial investigative research indicated that the essential oil from Chimonanthus nitens Oliv. Leaves (CLO) significantly reduces lung tissues inflammation and effectively repairs Acute lung injury (ALI) mice model. However, the mechanism underlying is not clear, and the impacts of CLO on oxidative stress require further investigation. AIM OF THE STUDY The purpose of the experiment was to validate the influence of CLO in ALI model mice, as well as its potential mechanisms. MATERIALS AND METHODS Lipopolysaccharide-induced establishment of the A549 cell inflammation model, and ALI mice model was established by intrathecal administration of LPS. RESULTS CLO significantly reduced the release of inflammatory cytokines in A549 cells, lowered MDA and ROS levels, and enhanced SOD activity. Animal experiment results showed that CLO dramatically decreased white blood cell count, the expression of inflammatory cytokines, and the destruction of alveolar structures. CLO enhances the activity of antioxidant enzymes. Western Blot and q-PCR analyses have revealed that the mechanism of CLO is correlation with the NF-κB and Nrf2 signaling pathways in cellular and animal models. Pathway inhibitor experiments indicated that there might be functional crosstalk between these two pathways. CONCLUSIONS CLO may regulate inflammation and oxidative stress in LPS-induced ALI through NF-κB and Nrf2 signaling pathways. This finding could be novel in the pharmacological treatment of ALI.

The therapeutic effect of Yinqiaosan decoction against influenza A virus infection by regulating T cell receptor signaling pathway. Heliyon 2024; 10:e36178. [PMID: 39253133 PMCID: PMC11382312 DOI: 10.1016/j.heliyon.2024.e36178] [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: 04/16/2024] [Revised: 08/08/2024] [Accepted: 08/12/2024] [Indexed: 09/11/2024] Open
Abstract
Background Yinqiaosan decoction (YQSD), a traditional Chinese medicinal recipe, has been employed to treat influenza in China for approximately 300 years. Objective Our study aimed to explore the mechanisms of YQSD against influenza via in vivo and in vitro experimental studies. Study design and methods UHPLC-Q-TOF-MS/MS was utilized to examine the substances of the YQSD. The chemical components of YQSD detected by UHPLC-Q-TOF-MS/MS were used for network pharmacology analysis. The antiviral effect of YQSD in vivo was investigated. The potential mechanisms of YQSD in combating influenza, which were predicted from network pharmacology analysis, were validated in vitro. Results By use of UHPLC-Q-TOF-MS/MS, 97 compounds were identified from YQSD. Network pharmacology analysis revealed that the therapeutic effect of YQSD against influenza may be associated with the regulation of T cell receptors (TCR) and Phosphoinositide 3-Kinase (PI3K)- protein kinase B (Akt) signaling pathways. Treatment with YQSD significantly prolonged the mean survival time of the mice and reduced lung injury due to the influenza A virus in vivo. It was discovered that YQSD efficiently inhibited the expression of inflammation-related cytokines. Moreover, YQSD has been found to significantly reduce the expression levels of cluster of differentiation 3 (CD3), monocyte chemoattractant protein-1 (MCP-1), and H1N1 virus nucleoprotein (NP), and prevent the decrease of epithelial cadherin (E-cadherin) protein. In addition, YQSD can inhibit the phosphorylation of the zeta chain of T cell receptor-associated protein kinase 70 (ZAP70) and PI3K proteins in vitro. Conclusion The capacity of YQSD to suppress viral multiplication and inflammatory response by modulating T cell immunity may explain its effect against influenza viral pneumonia, which may involve the regulation of TCR and PI3K signaling pathways.

Mailuoning oral liquid ameliorates vasculitis in thromboangiitis obliterans rats via inactivating cGAS-STING-IRF3 and TLR4-MAPKs/NF-κB signaling pathways. JOURNAL OF ETHNOPHARMACOLOGY 2024; 337:118707. [PMID: 39181282 DOI: 10.1016/j.jep.2024.118707] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/11/2024] [Revised: 08/07/2024] [Accepted: 08/17/2024] [Indexed: 08/27/2024]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Mailuoning oral liquid (MLN O), one traditional Chinese patent medicine, has a good therapeutic effect on thromboangiitis obliterans (TAO) in clinical practice. However, the underlying mechanism remains unclear. AIM OF THE STUDY This study aimed to explore the effects and potential mechanisms of MLN O against TAO based on network pharmacology and experimental verification. MATERIALS AND METHODS Network pharmacology was used to identify the intersectional targets and signaling pathways of MLN O and TAO. In vivo, the TAO model was established by injecting sodium laurate and dihydrotestosterone (DHT) into the femoral arteries of Wistar rats. Rats were given the indicated drugs by intragastric administration (i.g.), intravenous injection (i.v.), or subcutaneous injection (s.c.) per day for 21 days since a week before surgery. In vitro, HUVECs, RAW264.7, and THP-1 cells were stimulated by LPS and DHT to simulate the pathological changes of TAO. The anti-inflammatory, anticoagulant, and immunomodulatory effects of MLN O were evaluated by histological observation, blood biochemical indexes detection, H&E staining, immunohistochemistry, enzyme-linked immunosorbent assay (ELISA), qRT-PCR, western blotting and immunofluorescence assays. Furthermore, the vascular ring test was applied to explore the vasodilatory activity of MLN O. RESULTS MLN O significantly improved the pathological signs in TAO rats through its excellent anti-inflammatory, anticoagulant, immunomodulatory, and vasodilatory effects. Specifically, MLN O alleviated the gangrene and reduced the thrombosis in TAO rats, meanwhile, suppressed the expressions of inflammatory factors and clotting factors, which is related to the inactivations of cGAS-STING-IRF3 and TLR4-MAPKs/NF-κB signaling pathways. However, the superphysiological dose of DHT deteriorated the pathological development of TAO in vitro and in vivo. Moreover, the results of network pharmacology are consistent with the experimental verification. CONCLUSION Collectively, this study indicates for the first time that MLN O could alleviate TAO by inhibiting cGAS-STING-IRF3 and TLR4-MAPKs/NF-κB signaling pathways, which sheds light on a novel clinical therapeutic strategy for TAO.

[PMID: 38339153 PMCID: PMC10856478 DOI: 10.3390/ijms25031875] [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: 12/17/2023] [Revised: 01/20/2024] [Accepted: 01/25/2024] [Indexed: 02/12/2024] Open
Abstract
Acute lung injury (ALI) is a serious inflammatory disease with high morbidity and mortality. Rosavin is an anti-inflammatory and antioxidant phenylpropanoid and glucoside, which is isolated from Rhodiola rosea L. However, its potential molecular mechanisms and whether it has protective effects against lipopolysaccharide (LPS)-induced ALI remain to be elucidated. To assess the in vitro anti-inflammatory effects and anti-lung injury activity of rosavin, RAW264.7 and A549 cells were stimulated using 1 μg/mL LPS. Rosavin attenuated LPS-induced activation of the TLR-4/NF-κB signaling pathway in RAW264.7 cells and inhibited LPS-induced release of inflammatory factors in A549 cells. A mouse model of acute lung injury was constructed by intraperitoneal injection of 5 mg/kg LPS to observe the therapeutic effect of rosavin. Transcriptomics analysis and Western blot assays were utilized to verify the molecular mechanism, rosavin (20, 40, and 80 mg/kg) dose-dependently ameliorated histopathological alterations, reduced the levels of inflammatory factors, and inhibited the TLR-4/NF-κB/MAPK signaling pathway and apoptosis activation. Rosavin is a promising therapeutic candidate for acute lung injury by inhibiting the TLR-4/NF-κB/MAPK pathway.

Ameliorative effect of scopolamine-induced cognitive dysfunction by Fufangmuniziqi formula: The roles of alkaloids, saponins, and flavonoids. JOURNAL OF ETHNOPHARMACOLOGY 2024; 318:116792. [PMID: 37356745 DOI: 10.1016/j.jep.2023.116792] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/26/2023] [Revised: 06/12/2023] [Accepted: 06/14/2023] [Indexed: 06/27/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Fufangmuniziqi formula (FFMN), a traditional Uyghur medicine used in China, is derived from an ancient Uyghur medical book and consists of 13 herbs. The herbs of FFMN, such as Peganum harmala L., Glycyrrhiza uralensis Fisch., and Nigella glandulifera, have been demonstrated to have acetylcholinesterase (AChE) inhibitory, anti-neuroinflammatory, or antioxidant effects. Therefore, FFMN may have a good anti-Alzheimer's disease (AD) effect, but its specific action and mechanism need to be further proven. AIM OF THE STUDY This study aims to investigate the anti-AD effects of FFMN and the role played by alkaloids, flavonoids, and saponins in anti-AD. MATERIALS AND METHODS The alkaloids, flavonoids, and saponins fractions of FFMN were prepared by macroporous resin chromatography. The absorbed ingredients in the drug-containing serum were identified by UPLC⁃Q⁃TOF⁃MS. An AD mouse model was established by intraperitoneal injection of scopolamine (SCO). The role of different fractions of FFMN in the anti-AD process was examined by Morris water maze (MWM), in-vitro cell, and AChE inhibition assay. RESULTS A total of 20 ingredients were identified in the serum samples collected after oral administration of FFMN, and seven compounds were selected as candidate active compounds. MWM experiments showed that different fractions of FFMN could significantly improve SCO-induced learning memory impairment in mice. The alkaloids fraction (ALK) regulated cholinergic function by inhibiting AChE activity, activating choline acetyltransferase activity, and protein expression. Flavonoids and saponins were more potent than the ALK in downregulating pro-inflammatory factors or inflammatory mediators, such as TNF-α, MPO, and nitric oxide. Western blot results further confirmed that flavonoids and saponins attenuated neuroinflammation by inhibiting the phosphorylation of IκB and NF-κB p65. This result was also verified by in-vitro cellular assays. FFMN enhanced antioxidant defense by increasing the activity of superoxide dismutase and reducing the production of MDA. Combined with cellular experiments, flavonoids and saponins were proven more protective against oxidative damage. CONCLUSION FFMN improved cognitive and memory impairment in the SCO-induced AD mouse model. ALK mainly enhanced the function of the cholinergic system. Flavonoid and saponin fractions mainly attenuated neuroinflammation and oxidative stress by modulating the NF-κB pathway. All these findings strongly suggested that the combination of alkaloid, flavonoid, and saponin fractions derived from FFMN is a promising anti-AD agent that deserves further development.

Abstract
Acute lung injury (ALI) is a common condition, particularly in the COVID-19 pandemic, which is distinguished by sudden onset of respiratory insufficiency with tachypnea, oxygen-refractory cyanosis, reduced lung compliance and diffuse infiltration of pulmonary alveoli. It is well-established that increasing activity of toll-like receptor 4 (TLR4)/nuclear factor kappa-B (NF-κB) signaling axis and the NOD-, LRR- and pyrin domain-containing protein 3 (NLRP3) inflammasome activation are associated with the pathogenesis of ALI. Since ALI poses a huge challenge to human health, it is urgent to tackle this affliction with therapeutic intervention. Qinhuo Shanggan oral solution (QHSG), a traditional Chinese herbal formula, is clinically used for effective medication of various lung diseases including ALI, with the action mechanism obscure. In the present study, with the rat model of lipopolysaccharide (LPS)-induced ALI, QHSG was unveiled to ameliorate ALI by alleviating the pathological features, reversing the alteration in white blood cell profile and impeding the production of inflammatory cytokines through down-regulation of TLR4/NF-κB signaling cascade and inhibition of NLRP3 inflammasome activation. In LPS-stimulated RAW264.7 mouse macrophages, QHSG was discovered to hinder the generation of inflammatory cytokines by lessening TLR4/NF-κB signaling pathway activity and weakening NLRP3 inflammasome activation. Taken together, QHSG may resolve acute lung injury, attributed to its anti-inflammation and immunoregulation by attenuation of TLR4/NF-κB signaling cascade and inhibition of NLRP3 inflammasome activation. Our findings provide a novel insight into the action mechanism of QHSG and lay a mechanistic foundation for therapeutic intervention in acute lung injury with QHSG in clinical practice.
