Abstract
Cerebral ischemia-reperfusion (IR) is the main pathophysiological process after stroke and can seriously impair neurological function. Wogonin, a natural flavonoid extracted from the roots of Scutellaria baicalensis, has potent anti-inflammatory properties. In this study, we investigated the protective mechanism of wogonin against middle cerebral artery occlusion (MCAO) and oxygen-glucose deprivation/reoxygenation (OGD/R) model-induced cerebral IR injury through adenosine 5'-monophosphate-activated protein kinase (AMPK)/sirtuin 1 (SIRT1)/NOD-like receptor family pyrin domain containing 3 (NLRP3) inflammasome axis. Our results showed that wogonin (20 mg/kg, intraperitoneal injection) effectively reduced infarct size, attenuated brain edema, improved neurological deficits, and alleviated histopathological damage. In addition, wogonin reduced microglial cell activation and inflammatory factors, including tumor necrosis factor alpha (TNF-α), interleukin-1β (IL-1β), IL-6, and IL-10, in brain tissue and serum after cerebral IR injury. Wogonin also effectively activated the AMPK/SIRT1 signaling pathway and inhibited NLPR3 inflammasome-related molecules upregulation in cerebral IR injury as well as in OGD/R-stimulated HT-22 cells. Furthermore, inhibition of the AMPK/SIRT1 signaling pathway by Compound C, an AMPK inhibitor, significantly reversed the protective effect of wogonin on OGD/R-induced NLRP3 inflammasome. Meanwhile, the protective effect of wogonin against brain IR injury was also reversed in the presence of compound C. These results suggest that wogonin ameliorates cerebral IR injruy-induced inflammation by inhibiting NLRP3 inflammasome through the AMPK/SIRT1 signaling pathway.

Antimicrobial Potential of Aqueous Extract of Giant Sword Fern and Ultra-High-Performance Liquid Chromatography-High-Resolution Mass Spectrometry Analysis. Molecules 2023; 28:6075. [PMID: 37630329 PMCID: PMC10460075 DOI: 10.3390/molecules28166075] [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: 07/02/2023] [Revised: 08/09/2023] [Accepted: 08/10/2023] [Indexed: 08/27/2023] Open
Abstract
Vibriosis and parasitic leech infestations cause the death of various farmed fish, such as groupers, hybrid groupers, sea bass, etc., in Malaysia and other Southeast Asian countries. In the absence of natural control agents, aquaculture operators rely on toxic chemicals to control Vibrio infections and parasitic leeches, which can have a negative impact on the environment and health. In the present study, we investigated the antivibrio and antiparasitic activities of the aqueous extract of giant sword fern (GSF) (Nephrolepis biserrata, Nephrolepidaceae, locally known as "Paku Pedang") against four Vibrio spp. and the parasitic leech Zeylanicobdella arugamensis, as well as its metabolic composition using the ultra-high-performance liquid chromatography-high-resolution mass spectrometry system (UHPLC-HRMS). The data show that the aqueous extract of GSF at a concentration of 100 mg/mL exhibits potent bactericidal activity against V. parahaemolyticus with a zone of inhibition of 19.5 mm. In addition, the extract showed dose-dependent activity against leeches, resulting in the complete killing of the parasitic leeches within a short period of 11-43 min when tested at concentrations ranging from 100 to 25 mg/mL. The UHPLC-HRMS analysis detected 118 metabolites in the aqueous extract of GSF. Flavonoids were the primary metabolites, followed by phenolic, aromatic, fatty acyl, terpenoid, vitamin and steroidal compounds. Notably, several of these metabolites possess antibacterial and antiparasitic properties, including cinnamaldehyde, cinnamic acid, apigenin, quercetin, cynaroside, luteolin, naringenin, wogonin, 6-gingerol, nicotinamide, abscisic acid, daidzein, salvianolic acid B, etc. Overall, our study shows the significant antibacterial and antiparasitic potential of the GSF aqueous extract, which demonstrates the presence of valuable secondary metabolites. Consequently, the aqueous extract is a promising natural alternative for the effective control of Vibrio infections and the treatment of parasitic leeches in aquaculture systems.
