Abstract
Acute pancreatitis (AP) is a severe gastrointestinal inflammatory disease with increasing mortality and morbidity. Glycyrrhiza glabra, commonly known as Liquorice, is a widely used plant containing bioactive compounds like Glycyrrhizin, which possesses diverse medicinal properties such as anti-inflammatory, antioxidant, antiviral, and anticancer activities. The objective of this study is to investigate the active components, relevant targets, and underlying mechanisms of the traditional Chinese medicine Glycyrrhiza glabra in the treatment of AP. Utilizing various computational biology methods, we explored the potential targets and molecular mechanisms through Glycyrrhizin supplementation. Computational results indicated that Glycyrrhizin shows promising pharmacological potential, particularly with mitogen-activated protein kinase 3 (MAPK3) protein (degree: 70), forming stable complexes with Glycyrrhizin through ionic and hydrogen bonding interactions, with a binding free energy (ΔGbind) of -33.01 ± 0.08 kcal/mol. Through in vitro experiments, we validated that Glycyrrhizin improves primary pancreatic acinar cell injury by inhibiting the MAPK/STAT3/AKT signaling pathway. Overall, MAPK3 emerges as a reliable target for Glycyrrhizin's therapeutic effects in AP treatment. This study provides novel insights into the active components and potential targets and molecular mechanisms of natural products.

Abstract
BACKGROUND Acute necrotizing pancreatitis is a serious pancreatic injury with limited effective treatments. This study aims to investigate the therapeutic effects of hesperidin on Larginine- induced acute pancreatitis and its potential targets. METHODS The authors induced acute pancreatitis in mice by administering two hourly intraperitoneal injections of L-arginine-HCl, and evaluated the impact of hesperidin on pancreatic and lung tissues, plasma amylase activity, and myeloperoxidase content. Additionally, necrosis and mitochondrial function was tested in primary pancreatic acinar cells. The interactions between hesperidin and proteins involved in necrosis and mitochondrial dysfunction were further invested using in silico molecular docking and molecular dynamic simulations. RESULTS Hesperidin effectively ameliorated the severity of acute necrotizing pancreatitis by reducing plasma amylase, pancreatic MPO, serum IL-6 levels, pancreatic edema, inflammation, and pancreatic necrosis. Hesperidin also protected against acute pancreatitis-associated lung injury and prevented acinar cell necrosis, mitochondrial membrane potential loss, and ATP depletion. In addition, hesperidin exhibited a high binding affinity with SIRT1 and increased the protein levels of SIRT1. The SIRT1 inhibitor EX527 abolished the protective effect of hesperidin against necrosis in acinar cells. CONCLUSION These findings indicate that hesperidin alleviates the severity of acute necrotizing pancreatitis by activating SIRT1, which may provide insight into the mechanisms of natural compounds in treating AP. Hesperidin has potential as a therapeutic agent for acute necrotizing pancreatitis and provides a new approach for novel therapeutic strategies.

Abstract
Acute pancreatitis (AP) is an acute inflammatory gastrointestinal disease, the mortality and morbility of which has been on the increase in the past years. Spermidine, a natural polyamine, has a wide range of pharmacological effects including anti-inflammation, antioxidation, anti-aging, and anti-tumorigenic. This study aimed to investigate the reliable targets and molecular mechanisms of spermidine in treating AP. By employing computational biology methods including network pharmacology, molecular docking, and molecular dynamics (MD) simulations, we explored the potential targets of spermidine in improving AP with dietary supplementation. The computational biology results revealed that spermidine had high degrees (degree: 18, betweenness: 38.91; degree: 18, betweenness: 206.41) and stable binding free energy (ΔGbind: - 12.81 ± 0.55 kcal/mol, - 15.00 ± 1.00 kcal/mol) with acetylcholinesterase (AchE) and serotonin transporter (5-HTT). Experimental validation demonstrates that spermidine treatment could reduce the necrosis and AchE activity in pancreatic acinar cells. Cellular thermal shift assay (CETSA) results revealed that spermidine could bind to and stabilize the 5-HTT protein in acinar cells. Moreover, spermidine treatment impeded the rise of the expression of 5-HTT in pancreatic tissues of caerulein induced acute pancreatitis mice. In conclusion, serotonin transporter might be a reliable target of spermidine in treating AP. This study provides new idea for the exploration of potential targets of natural compounds.

Abstract
Acute biliary pancreatitis (ABP) with a high mortality rate is an incurable digestive system disease induced by abnormal bile acid regurgitation due to the biliary obstruction. Dehydrocholic acid (DA) alleviates the severity of cholestatic hepatitis related to biliary inflammation, suggesting DA is potential to develop for the incurable ABP management. Here we identified DA potency and explored the underlying mechanism in ABP. Our data showed that DA administration not only reduced typically clinicopathological parameters including serum levels of amylase and lipase but also suppressed pancreatic tissue edema, necrosis and trypsin activation in ABP mice. We also found that DA significantly reduced the necrosis of pancreatic acinar cells induced by sodium taurocholate (NaT). Further experimental data showed the significant inhibitions of DA on mitochondrial membrane potential depolarization, ATP exhaustion, calcium overload and reactive oxygen species (ROS) erupted in acinar cells induced by NaT, indicating DA could avert acinar cell death through protecting the mitochondrial function, scavenging excessive oxidative stress and balancing calcium. The comprehensive study found DA elevated the expression of transcription factor EB (TFEB) in vitro thus to increase the functional lysosome content. Indeed, DA decreased the Microtubule-associated protein light chain 3 (LC3) II/I ratio as well as ubiquitin-binding protein p62 and Parkin expressions in vivo and in vitro, revealing autophagy restoration maybe through the improvement of TFEB-mediated lysosome biogenesis. These data indicate that DA improves ABP through the mitochondrial protection, antioxidant ability enhancement and autophagy recovery. In conclusion, our study proposes a potential therapy strategy for the incurable ABP.

Abstract
OBJECTIVES In this study, we focused on the function of nuclear factor E2-related factor 2 (Nrf2) in acute pancreatitis (AP), which has been shown to have protective effects in gliomas, hepatocytes, and astrocytes. METHODS Acute pancreatitis cell line and animal model were induced by administration of lipopolysaccharide and cerulein into the cell supernatant or intraperitoneal injection. Oxidative stress status was evaluated by measuring the level of amylase, C-reactive protein, malondialdehyde, superoxide dismutase, and myeloperoxidase. Morphological alterations in the pancreas were evaluated by hematoxylin-eosin staining, the wet-to-dry weight ratio, and the pathology injury scores. Western blot, reverse transcription-polymerase chain reaction, and immunofluorescence staining were performed to analyze the expression of Nrf2, Heme oxygenase 1, and NAD(P)H: quinone oxidoreductase 1. RESULTS Overexpression of Nrf2 inhibits oxidative stress and inflammatory responses by inducting the expression of superoxide dismutase as well as reducing the level of amylase, malondialdehyde, and myeloperoxidase in the AR42J rat pancreatic acinar cells in AP. Importantly, overexpression of Nrf2 displayed the same protective effect in vivo. Data from an AP rat model showed that Nrf2 could relieve pancreatic damage. CONCLUSIONS These results indicated that Nrf2 has a protective role in lipopolysaccharide and cerulein-induced cytotoxicity, providing potential therapeutic strategies for the treatment of AP.

Protective effects of flavonoids from Coreopsis tinctoria Nutt. on experimental acute pancreatitis via Nrf-2/ARE-mediated antioxidant pathways. JOURNAL OF ETHNOPHARMACOLOGY 2018; 224:261-272. [PMID: 29870787 DOI: 10.1016/j.jep.2018.06.003] [Citation(s) in RCA: 37] [Impact Index Per Article: 6.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Subscribe] [Scholar Register] [Received: 12/12/2017] [Revised: 05/12/2018] [Accepted: 06/01/2018] [Indexed: 02/06/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Oxidative stress is a prominent feature of clinical acute pancreatitis (AP). Coreopsis tinctoria has been used traditionally to treat pancreas disorders like diabetes mellitus in China and Portugal and its flavonoid-rich fraction contain the main phytochemicals that have antioxidant and anti-inflammatory activities. AIM OF THE STUDY To investigate the effects of flavonoids isolated from C. tinctoria on experimental AP and explore the potential mechanism. MATERIALS AND METHODS LC-MS based online technique was used to analyse and isolate targeted flavonoids from C. tinctoria. Freshly isolated mouse pancreatic acinar cells were treated with taurocholic acid sodium salt hydrate (NaT, 5 mM) with or without flavonoids. Fluorescence microscopy and a plate reader were used to determine necrotic cell death pathway activation (propidium iodide), reactive oxygen species (ROS) production (H2-DCFDA) and ATP depletion (luminescence) where appropriate. AP was induced by 7 repeated intraperitoneal caerulein injections (50 μg/kg) at hourly interval in mice or retrograde infusion of taurolithocholic acid 3-sulfate disodium salt (TLCS; 5 mM, 50 μL) into the pancreatic duct in mice or infusion of NaT (3.5%, 1 mL/kg) in rats. A flavonoid was intraperitoneally administered at 0, 4, and 8 h after the first caerulein injection or post-operation. Disease severity, oxidative stress and antioxidant markers were determined. RESULTS Total flavonoids extract and flavonoids 1-6 (C1-C6) exhibited different capacities in reducing necrotic cell death pathway activation with 0.5 mM C1, (2 R,3 R)-taxifolin 7-O-β-D-glucopyranoside, having the best effect. C1 also significantly reduced NaT-induced ROS production and ATP depletion. C1 at 12.5 mg/kg and 8.7 mg/kg (equivalent to 12.5 mg/kg for mice) significantly reduced histopathological, biochemical and immunological parameters in the caerulein-, TLCS- and NaT-induced AP models, respectively. C1 administration increased pancreatic nuclear factor erythroid 2-related factor 2 (Nrf2) and Nrf2-medicated haeme oxygenase-1 expression and elevated pancreatic antioxidant enzymes superoxide dismutase and glutathione peroxidase levels. CONCLUSIONS Flavonoid C1 from C. tinctoria was protective in experimental AP and this effect may at least in part be attributed to its antioxidant effects by activation of Nrf2-mediated pathways. These results suggest the potential utilisation of C. tinctoria to treat AP.

Abstract
BACKGROUND AND PURPOSE Acute pancreatitis (AP) is a painful and distressing disorder of the exocrine pancreas with no specific treatment. Diosgenyl saponins extracted from from Dioscorea zingiberensis C. H. Wright have been reported to protect against experimental models of AP. Diosgenin, or its derivatives are anti-inflammatory in various conditions. However, the effects of diosgenin and its spiroacetal ring opened analogue, dihydrodiosgenin (Dydio), on AP have not been determined. EXPERIMENTAL APPROACH Effects of diosgenin and Dydio on sodium taurocholate hydrate (Tauro)-induced necrosis were tested, using freshly isolated murine pancreatic acinar cells. Effects of Dydio on mitochondrial dysfunction in response to Tauro, cholecystokinin-8 and palmitoleic acid ethyl ester were also assessed. Dydio (5 or 10 mg·kg-1 ) was administered after the induction in vivo of Tauro-induced AP (Wistar rats), caerulein-induced AP and palmitoleic acid plus ethanol-induced AP (Balb/c mice). Pancreatitis was assessed biochemically and histologically. Activation of pancreatic PI3Kγ/Akt was measured by immunoblotting. KEY RESULTS Dydio inhibited Tauro-induced activation of the necrotic cell death pathway and prevented pancreatitis stimuli-induced mitochondrial dysfunction. Therapeutic administration of Dydio ameliorated biochemical and histopathological responses in all three models of AP through pancreatic mitochondrial protection and PI3Kγ/Akt inactivation. Moreover, Dydio improved pancreatitis-associated acute lung injury through preventing excessive inflammatory responses. CONCLUSION AND IMPLICATIONS These data provide in vitro and in vivo mechanistic evidence that the diosgenin analogue, Dydio could be potential treatment for AP. Further medicinal optimization of diosgenin and its analogue might be a useful strategy for identifying lead candidates for inflammatory diseases.
