Abstract
Research has shown that neuronal ferroptosis is associated with various central nervous system diseases, including Parkinson's disease, acute brain injury, and spinal cord injury. Inhibiting neuronal ferroptosis can greatly alleviate the progression of these diseases. However, there is currently a lack of effective drugs to inhibit neuronal ferroptosis. In this study, we pretreated neuronal cells with Hispolon and subsequently induced a neuronal ferroptosis model using Erastin. We further assessed the changes in the protein expression levels of SLC7A11, GPX4, ACSL4, Nrf-2, and HO-1 using Western blot and immunofluorescence techniques. Additionally, we measured the intracellular levels of Fe2+, GSH, and MDA using relevant assay kits. The research findings revealed that after Hispolon treatment, the expression of the pro-ferroptosis protein ACSL4 decreased, while the expression of the ferroptosis-regulating proteins GPX4 and SLC7A11 increased. Moreover, the use of an Nrf-2-specific inhibitor was able to reverse the effects of Hispolon as mentioned above. In this study, we discovered that Hispolon can promote the expression of Nrf-2 and inhibit the occurrence of neuronal ferroptosis induced by Erastin.

BMC Complement Med Ther 2023; 23:437. [PMID: 38049800 PMCID: PMC10696755 DOI: 10.1186/s12906-023-04264-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/31/2023] [Accepted: 11/17/2023] [Indexed: 12/06/2023] Open
Abstract
CONTEXT Inflammation has been identified as a key factor contributing to the development of numerous diseases. Several anti-inflammatory drugs have been developed to treat inflammation-related diseases. However, some of such drugs are associated with varying degrees of side effects. Therefore, it is imperative to develop new anti-inflammatory drugs with reducing side effects for the treatment of inflammation-related diseases. Natural anti-inflammatory drugs have emerged as an important area of research in recent years. The study was to determine the anti-inflammatory mechanism of Paridis rhizoma extract (PRE) in rat models of acute inflammation induced by carrageenan and RAW264.7 cells models induced by lipopolysaccharide (LPS). MATERIALS AND METHODS PRE was investigated using the carrageenan-induced paw oedema model on rats in vivo. Histopathology examined the extent of inflammatory infiltration and tissue damage. The effect of PRE on the levels of specific cytokines was determined using enzyme-linked immunosorbent assay (ELISA). The Cell Counting Kit (CCK)-8 assay evaluated the cytotoxic effects of PRE on Raw264.7 cells. The mRNA expression levels of cytokines were quantified using quantitative real-time reverse transcriptase polymerase chain reaction (RT-PCR). Western blot measured TNF-α, IL6, TLR4, p-P65, p-IKB, HO1, SOD1 and SOD2. Fluorescence measured the cellular levels of reactive oxygen species (ROS). RESULTS PRE treatment reduced interstitial edema and structural damage in a dose-dependent manner in vivo. PRE inhibited inflammatory responses in vivo and in vitro, as evidenced by the decreased expression of inflammatory factors, production of ROS, and increased expression of SOD1, SOD2, and HO1. Moreover, PRE inhibited the activity of the nuclear factor kappa B (NF-kB) pathway. CONCLUSION The anti-inflammatory activity and potential mechanism of PRE were demonstrated according to the results. PRE reduced LPS-induced inflammation in RAW264.7 cells by inhibiting the NF-KB signaling pathway and ROS production in vitro. PRE alleviated interstitial edema and structural damage in the carrageenan-induced paw edema model on rats in vivo. This study provided an idea for future development of PR-based anti-inflammatory drugs.

Phenethylferulate as a natural inhibitor of inflammation in LPS-stimulated RAW 264.7 macrophages: focus on NF-κB, Akt and MAPK signaling pathways. BMC Complement Med Ther 2023; 23:398. [PMID: 37936108 PMCID: PMC10629144 DOI: 10.1186/s12906-023-04234-y] [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: 04/20/2023] [Accepted: 10/24/2023] [Indexed: 11/09/2023] Open
Abstract
BACKGROUND Notopterygii Rhizoma et Radix (NRR) is commonly used for the treatment of inflammation-linked diseases. Phenethylferulate (PF) is high content in NRR crude, but its anti-inflammatory effect remains unclear. Therefore, we aimed to investigate the anti-inflammatory properties of PF and its underlying molecular mechanisms in lipopolysaccharide (LPS)-stimulated RAW 264.7 macrophages. METHODS The effect of PF on cell viability was measured by MTT assay. The anti-inflammatory properties of PF were studied by detecting the levels of inflammatory mediators and cytokines using enzyme-linked immunosorbent assay (ELISA). Furthermore, the anti-inflammatory mechanisms of PF were determined by Western blot analysis. RESULTS PF was not cytotoxic to RAW 264.7 macrophages at the concentrations of below 48 μM. ELISA showed that PF conspicuously inhibited overproduction of prostaglandin E2 (PGE2), tumor necrosis factor α (TNF-α), interleukin 1β (IL-1β) and interleukin 6 (IL-6). Western blot analysis showed that PF remarkably suppressed overproduction of inducible nitric oxide synthase (iNOS) and cyclooxygenase 2 (COX-2), the phosphorylation of inhibitor of NF-κB kinase α (IκB-α), protein kinase B (Akt), extracellular signal-regulated kinase (ERK), c-Jun N-terminal kinases (JNK) and p38, as well as the degradation and subsequent nuclear translocation of p65. CONCLUSIONS PF is a potent inhibitor of inflammation acting on nuclear factor kappa-B (NF-κB), Akt and mitogen-activated protein kinase (MAPK) signaling pathways in LPS-stimulated RAW 264.7 macrophages. This work provides evidence for the suitability of PF as a therapeutic candidate for the management of inflammatory-mediated immune disorders.

Hispolon Cyclodextrin Complexes and Their Inclusion in Liposomes for Enhanced Delivery in Melanoma Cell Lines. Int J Mol Sci 2022; 23:ijms232214487. [PMID: 36430965 PMCID: PMC9695989 DOI: 10.3390/ijms232214487] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/10/2022] [Revised: 11/11/2022] [Accepted: 11/17/2022] [Indexed: 11/23/2022] Open
Abstract
Hispolon, a phenolic pigment isolated from the mushroom species Phellinus linteus, has been investigated for anti-inflammatory, antioxidant, and anticancer properties; however, low solubility and poor bioavailability have limited its potential clinical translation. In this study, the inclusion complex of hispolon with Sulfobutylether-β-cyclodextrin (SBEβCD) was characterized, and the Hispolon-SBEβCD Complex (HSC) was included within the sterically stabilized liposomes (SL) to further investigate its anticancer activity against melanoma cell lines. The HSC-trapped-Liposome (HSC-SL) formulation was investigated for its sustained drug delivery and enhanced cytotoxicity. The inclusion complex in the solid=state was confirmed by a Job’s plot analysis, molecular modeling, differential scanning calorimetry (DSC), Fourier transform infrared spectroscopy (FTIR), Proton nuclear magnetic resonance (NMR) spectroscopy, and scanning electron microscopy (SEM). The HSC-SL showed no appreciable deviation in size (<150 nm) and polydispersity index (<0.2) and improved drug encapsulation efficiency (>90%) as compared to control hispolon liposomes. Individually incorporated hispolon and SBEβCD in the liposomes (H-CD-SL) was not significant in loading the drug in the liposomes, compared to HSC-SL, as a substantial amount of free drug was separated during dialysis. The HSC-SL formulation showed a sustained release compared to hispolon liposomes (H-SLs) and Hispolon-SBEβCD liposomes (H-CD-SLs). The anticancer activity on melanoma cell lines (B16BL6) of HSC and HSC-SL was higher than in H-CD-SL and hispolon solution. These findings suggest that HSC inclusion in the HSC-SL liposomes stands out as a potential formulation approach for enhancing drug loading, encapsulation, and chemotherapeutic efficiency of hispolon and similar water insoluble drug molecules.
