Abstract
Acute lung injury is significantly associated with the aberrant activation and pyroptosis of alveolar macrophages. Targeting the GPR18 receptor presents a potential therapeutic approach to mitigate inflammation. Verbenalin, a prominent component of Verbena in Xuanfeibaidu (XFBD) granules, is recommended for treating COVID-19. In this study, we demonstrate the therapeutic effect of verbenalin on lung injury through direct binding to the GPR18 receptor. Verbenalin inhibits the activation of inflammatory signaling pathways induced by lipopolysaccharide (LPS) and IgG immune complex (IgG IC) via GPR18 receptor activation. The structural basis for verbenalin's effect on GPR18 activation is elucidated through molecular docking and molecular dynamics simulations. Furthermore, we establish that IgG IC induces macrophage pyroptosis by upregulating the expression of GSDME and GSDMD through CEBP-δ activation, while verbenalin inhibits this process. Additionally, we provide the first evidence that IgG IC promotes the formation of neutrophil extracellular traps (NETs), and verbenalin suppresses NETs formation. Collectively, our findings indicate that verbenalin functions as a "phytoresolvin" to promote inflammation regression and suggests that targeting the C/EBP-δ/GSDMD/GSDME axis to inhibit macrophage pyroptosis may represent a novel strategy for treating acute lung injury and sepsis.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Verbenalin is a major compound in Verbena officinalis L. Verbena officinalis L was first recorded in the 'Supplementary Records of Famous Physicians.' Verbenalin (VE) is its active constituent and has been found to have many biological effects, including anti-obesity, anti-inflammatory, and antioxidant activities, removing jaundice, and treating malaria. It could treat lump accumulation, dysmenorrhea, throat obstruction, edema, jaundice, and malaria. Palmitic acid (PA), oleic acid (OA), ethanol, and acetaminophen liver injuries have been proven to benefit from verbenalin. AIM OF THE STUDY To study the effects of verbenalin on the prevention of alcoholic steatohepatitis (ASH) through the regulation of oxidative stress and mitochondrial dysfunction by regulating MDMX (Murine double minute X)/PPARα (Peroxisome proliferator-activated receptor alpha)-mediated ferroptosis. MATERIAL AND METHODS C57BL/6 mice treated with alcohol followed by the Gao-Binge protocol were administered verbenalin by gavage simultaneously. The mitochondrial mass and morphology were visualized using TEM. AML-12 cells were stimulated with ethanol to mimic ASH in vitro. Western blotting, co-immunoprecipitation, and kit determination were simultaneously performed. The target protein of verbenalin was identified by molecular docking, and cellular thermal shift assay (CETSA) further confirmed its interactions. RESULTS Verbenalin alleviates oxidative stress and ferroptosis in alcohol-associated steatohepatitis. To elucidate the molecular mechanism by which verbenalin inhibits abnormal mitochondrial dysfunction, molecular docking was performed, and MDMX was identified as the target protein of verbenalin. CETSA assays revealed a specific interaction between MDMX and verbenalin. Co-immunoprecipitation demonstrated that PPARα played a critical role in promoting the ability of MDMX to affect ferroptosis. Verbenalin regulates MDMX/PPARα-mediated ferroptosis in AML-12 cells. CONCLUSION Verbenalin regulates ferroptosis and highlights the therapeutic potential of verbenalin and ferroptosis inhibition in reducing alcoholic steatohepatitis.

Abstract
BACKGROUND The purpose of this research was to study whether verbenalin, an iridoid glucoside, and (+)-eudesmin, a furofuran lignan isolated from different plant families, can attenuate cell damage and death induced by 6-hydroxydopamine (6-OHDA) in human neuroblastoma SH-SY5Y cells. METHODS SH-SY5Y cells were incubated with 6-OHDA (35 µM) for 1 day. Verbenalin and (+)-eudesmin were administrated with various concentrations (1, 2.5, 5, 10, 20, and 50 µM) one hour before the 6-OHDA treatment. After 1 day, cell viability and neuroprotective effect were investigated with 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) and lactate dehydrogenase (LDH) assays. Nitrosative stress was determined with measurements of nitric oxide (NO) and 3-nitrotyrosine (3-NT), a biomarker of peroxynitrite formation. RESULTS We observed that 6-OHDA declined viability and augmented LDH leakage in SH-SY5Y cells. MTT analyses showed that pretreatment with verbenalin and (+)-eudesmin markedly prevented the toxicity due to 6-OHDA (P < 0.05). Verbenalin and (+)-eudesmin suppressed LDH release induced by 6-OHDA (P < 0.01). Although 6-OHDA treatment produced no marked effects on NO levels, (+)-eudesmin at high concentrations (10-50 µM) markedly attenuated NO levels (P < 0.01). There was a significant increase in 3-NT levels with 6-OHDA exposure in cells. Pretreatment with verbenalin, but not (+)-eudesmin, diminished 3-NT levels at low concentrations (1-20 µM) and prevented the cytotoxic effect of 6-OHDA (P < 0.01). CONCLUSION These results indicated that verbenalin and (+)-eudesmin exert potent cytoprotective activities against cytotoxicity triggered by 6-OHDA in neuroblastoma cells. This is the first report demonstrating that verbenalin may act as a peroxynitrite scavenger.

Abstract
To investigate the protective mechanism of verbenalin on cerebral ischemia-reperfusion injury. Middle cerebral artery occlusion in the left hemisphere was induced in rats by filament insertion, and rat model of focal cerebral ischemia-reperfusion was established. The high, medium and low dose of verbenalin groups were injected in the tail vein of corresponding drugs 10 min before reperfusion, and submitted for 22 h of reperfusion after the operation. Mortality rate was then calculated, and neurological deficits of rats were scored. The serum of rats was got to determine the S-100β protein level, and the brain tissue was removed to determine the levels of Bax, Bcl-2, Caspase-3 and ATPase. TTC staining was performed on the brain tissue to calculate the percentage of cerebral infarct size. Changes in brain tissue morphology were observed. Rat model of focal cerebral ischemia-reperfusion was successfully replicated. In groups that have taken different doses of verbenalin, the mortality rate, neurological deficit score and the percentage of cerebral infarction size were significantly reduced, and the levels of Bax, Caspase-3, S-100β level of the serum in the brain tissue were also significantly reduced. Increases in the levels of Bcl-2 and ATPase in brain tissue and improvement of pathological damage of hippocampus and cortex were observed. Verbenalin can inhibit the expression of apoptosis genes, promote the expression of anti-apoptosis genes, improve brain microcirculation and energy metabolism, hence reducing cerebral ischemia-reperfusion injury.

Abstract
BACKGROUND Shufengjiedu Capsule (SFJD) is a type of Chinese traditional medicine compound for the treatment of acute upper respiratory tract infection. The present work aims to decipher the mechanism of SFJD. METHODS In this study, we used target prediction and RNA sequence (RNA-Seq) based on transcriptome analysis to clarify the inflammation-eliminating mechanism of SFJD. Firstly, Pseudomonas aeruginosa (PAK) was used to induce acute lung injury in KM mice. After being treated by SFJD, the differently expressed genes were analyzed by RNA-Seq. Secondly, the chemical constituents of SFJD were identified by ultra-performance liquid chromatography quadrupole/time of flight mass spectrometry (UPLC/Q-TOF-MS) and submitted to PharmMapper to predict targets. The Kyoto Encyclopedia of Genes and Genomes (KEGG) and String 9.1 websites were employed to establish the interaction network of inflammation of these targets. RESULTS The results indicated that SFJD alleviated PAK induced lung injury in KM mice. We infer that the mechanism is a complex network containing 15 pathways related to inflammation regulated by 16 types of components from six types of herbs via 29 proteins. The ERK signaling pathway was a key pathway among them, which was predicted to be regulated by 14 types of components in SFJD. Phillyrin, emodin, and verbenalin were screened out by binding capacity, and the synergistic effect of them was further confirmed. CONCLUSIONS Various components of SFJD ameliorated PAK induced upper respiratory tract infection via multiple targets, of which ERK phosphorylation might be the key event regulated specifically by verbenalin, phillyrin and emodin.
