Li M, Fu F, Wang T. Escin alleviates cerebral ischemia-induced intestinal pyroptosis via the GR-dependent p38 MAPK/NF-κB signaling and NLRP3 inflammasome activation. Int Immunopharmacol 2024; 138:112592. [PMID: 38955024 DOI: 10.1016/j.intimp.2024.112592] [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: 04/25/2024] [Revised: 06/26/2024] [Accepted: 06/27/2024] [Indexed: 07/04/2024]
Abstract
Cerebral ischemia-induced systemic inflammation and inflammasome-dependent pyroptotic cell death in ileum, causing serious intestinal injury. Glucocorticoid receptor (GR) mediates the effects of glucocorticoids and participates in inflammation. Escin has corticosteroid-like, neuroprotective, and anti-intestinal dysfunction effects. This study aimed to investigate the effect of Escin on the intestinal barrier injury in rats subjected to middle cerebral artery occlusion (MCAO) and on Caco-2 cells exposed to lipopolysaccharides. The MCAO-caused brain injury was evaluated by assessing neurological function, cerebral infarct volume, and plasma corticosterone (Cort) levels. Intestinal injury was evaluated by observing the histopathological changes, assessing the intestinal barrier function, and determining blood FD4, endotoxin and IL-1β levels. The levels of the tight-junction proteins such as claudin-1, occludin, and ZO-1, and proteins involved in the GR/p38 MAPK/NF-κB pathway and NLRP3-inflammasome activation were evaluated using western blotting or immunofluorescence. Administration of Escin suppressed the cerebral ischemia-induced increases in Garcia-test scores and infarct volume, alleviated the injury to the intestinal barrier, and decreased the levels of Cort, endotoxin, and IL-1β. Additionally, Escin upregulated GR and downregulated phospho(p)-p65, p-p38MAPK, NLRP3, GSDMD-N, and cleaved-caspase-1 in the intestine. The effects of Escin could be suppressed by the GR antagonist RU486 or enhanced by the p38 MAPK antagonist SB203580. We revealed details how Escin improves cerebral ischemia-induced intestinal barrier injury by upregulating GR and thereby inhibiting the pyroptosis induced by NF-κB-mediated NLRP3 activation. This study will provide a experimental foundation for the features of glucocorticoid-like activity and the discovery of new clinical application for Escin.

Asian J Surg 2024:S1015-9584(24)01711-1. [PMID: 39153932 DOI: 10.1016/j.asjsur.2024.07.336] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/14/2024] [Revised: 07/22/2024] [Accepted: 07/29/2024] [Indexed: 08/19/2024] Open
Abstract
BACKGROUND Hemorrhoidal disease, affecting over 20 % of the population, presents management challenges due to its multifaceted nature. While treatments like Micronized Purified Flavonoid Fraction (MPFF) show promise, Aescin's efficacy remains uncertain. This study assesses the combined effectiveness of Aescin with MPFF against MPFF alone in treating Grades 1 and 2 hemorrhoids, focusing on halting bleeding and reducing mass effect. METHOD This study recruited patients from the Division of Colorectal Surgery, Chiang Mai University. Patients were randomly assigned to receive MPFF alone or MPFF with Aescin. Outcomes included the duration until bleeding cessation and resolution of mass effect. RESULTS Of 120 patients randomized to each group, the combination therapy demonstrated superiority in halting bleeding (two days VS four days) and resolving mass effect (four days VS five days) compared to MPFF alone with statistically significant differences. Treatment failure rates were lower in the combination therapy group, with high patient satisfaction. CONCLUSION Combining Aescin with MPFF shows promise as a therapeutic approach for Grades 1 and 2 internal hemorrhoids, offering expedited relief from bleeding and mass effect. These findings suggest the need for further research to validate results in larger cohorts and optimize treatment strategies for hemorrhoidal disease.

PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2023; 120:155071. [PMID: 37716034 DOI: 10.1016/j.phymed.2023.155071] [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: 04/06/2023] [Revised: 08/10/2023] [Accepted: 09/04/2023] [Indexed: 09/18/2023]
Abstract
BACKGROUND Hemorrhagic transformation (HT) seriously affects the clinical application of recombinant tissue plasminogen activator (rt-PA). The main strategy for combating HT is to keep the blood-brain barrier (BBB) stable. Escin is the active ingredient of Aesculus hippocastanum and a natural mixture of triterpene saponins, and may play a part in mitigation of HT. PURPOSE This study sought to investigate the effect of Escin in improving rt-PA-induced HT, explore possible mechanisms, and provide new ideas for the treatment of clinical HT. STUDY DESIGN AND METHODS In in vivo experiments, transient middle cerebral artery occlusion (tMCAO) was undertaken in 6-week-old and 12-month-old mice, and rt-PA was administered to induce HT injury. The inhibitory effect of Escin on HT and its protective effect on neurobehavior, the BBB, and cerebrovascular endothelial cells was determined. In in vitro experiments, bEnd.3 cells were injured by oxygen-glucose deprivation/reperfusion (OGD/R) and rt-PA. The protective effect of Escin was measured by the CCK8 assay, release of lactate dehydrogenase (LDH), and expression of tight junction (TJ) proteins. In mechanistic studies, the effect of Escin on the adenosine monophosphate-activated kinase / caveolin-1 / matrix metalloprotease-9 (AMPK/Cav-1/MMP-9) pathway was investigated by employing AMPK inhibitor and Cav-1 siRNA. RESULTS In mice suffering from ischemia, rt-PA caused HT as well as damage to the BBB and cerebrovascular endothelial cells. Escin reduced the infarct volume, cerebral hemorrhage, improved neurobehavioral deficits, and maintained BBB integrity in rt-PA-treated tMCAO mice while attenuating bEnd.3 cells damage caused by rt-PA and OGD/R injury. Under physiological and pathological conditions, Escin increased the expression of p-AMPK and Cav-1, leading to decreased expression of MMP-9, which further attenuated damage to cerebrovascular endothelial cells, and these effects were verified with AMPK inhibitor and Cav-1 siRNA. CONCLUSION We revealed important details of how Escin protects cerebrovascular endothelial cells from HT, these effects were associated with the AMPK/Cav-1/MMP-9 pathway. This study provides experimental foundation for the development of new drugs to mitigate rt-PA-induced HT and the discovery of new clinical application for Escin.

Abstract
[Formula: see text]-Escin is an oleanane-type pentacyclic triterpenoid saponin extracted from the seeds of Aesculus hippocastanum (AH), which is more widely distributed. [Formula: see text]-Escin sodium has been approved by the American FDA for clinical usage. This paper is intended to summarize an updated and comprehensive review of the pharmacological activities, pharmacokinetic properties, toxicity, and analytical methods of [Formula: see text]-escin. Studies have shown that [Formula: see text]-escin has significant antitumor, antiviral, anti-inflammatory, and other activities alongside less adverse effects and higher safety than other compounds. The review shows that the pharmacological effects of [Formula: see text]-escin involve mechanisms such as ATM/[Formula: see text]H2AX, RhoA/Rock, GSK-3[Formula: see text]/[Formula: see text]-Catenin, HER2/HER3/Akt, and PI3K/Akt signaling pathways, and Cyclin A, p21[Formula: see text], survivin, Bcl-2, Mcl-1, Caspases, TGF-[Formula: see text], MMPs, and TNF-[Formula: see text] among other inflammatory factors. [Formula: see text]-Escin has significant cytotoxicity; the use of the chitosan/xanthan gum-based polyelectrolyte complexes PA1 and PC-11 to modify it not only to reduces its toxicity, but also improves its drug efficacy. Because of this, these compounds may become a new research hotspot. [Formula: see text]-Escin in vivo metabolism can be converted by the CYP1A2 enzyme in the intestinal flora to produce [Formula: see text]-escin, deacylated, deglycosylated, and 21[Formula: see text]-[Formula: see text]-crotonoyl-protoescin, and the binding rate of the plasma proteins is higher than 90%. These are mainly metabolized by the liver, kidneys, and other organs, and excreted in the form of urine and feces. The number of reports on the specific mediators of the metabolism of [Formula: see text]-escin and their mechanisms and metabolites is relatively small; furthermore, the results are vague. Therefore, a complete and in-depth exploration of the pharmacokinetic characteristics of [Formula: see text]-escin is needed to provide a more complete and effective theoretical reference for the study of its pharmacodynamic activity.

Abstract
Hyperactivity of HPA axis results in intestinal dysfunction, which may play a role in brain injury caused by ischemic stroke (IS). Escin shows a neuroprotective effect but it may not penetrate blood brain barrier (BBB). Previous work in our laboratory showed that escin ameliorated intestinal injury in animals. The aim of this study is to investigate whether escin attenuates brain injury by improving intestinal dysfunction in middle cerebral artery occlusion (MCAO) rats, to mimic IS. MCAO rats and lipopolysaccharides (LPS)-induced Caco-2 cells were used to evaluate the effects of escin in vivo and in vitro. The results showed that escin could not penetrate BBB but reduced brain infarct volume, improved neurological function, inhibited neuroinflammation, ameliorated intestinal dysfunction and tissue integrity by increasing the expression of the tight junction protein in vivo and in vitro. Escin reduced the increased corticosterone and endotoxin level in blood of MCAO rats, regulated GR/p38 MAPK/NF-κB signaling pathway in ileal tissue and LPS/TLR4/NF-κB signaling pathway in ischemic brain tissue. These findings suggest that escin could attenuate ischemic brain injury by improving intestinal dysfunction, and it may be a promising way to protect brain injury by protecting intestine, instead of targeting the brain directly after IS.

Antihyaluronidase and Antioxidant Potential of Atriplex sagittata Borkh. in Relation to Phenolic Compounds and Triterpene Saponins. Molecules 2023; 28:molecules28030982. [PMID: 36770647 PMCID: PMC9921161 DOI: 10.3390/molecules28030982] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/21/2022] [Revised: 01/12/2023] [Accepted: 01/16/2023] [Indexed: 01/21/2023] Open
Abstract
The genus Atriplex provides species that are used as food and natural remedies. In this work, the levels of soluble phenolic acids (free and conjugated) and flavonoids in extracts from roots, stems, leaves and flowers of the unexplored Atriplex sagittata Borkh were investigated by LC-ESI-MS/MS, together with their antioxidant and antihyaluronidase activity. Phenolic acids were present in all parts of A. sagittata; and were most abundant in the leaves (225.24 μg/g dw.), whereas the highest content of flavonoids were found in the flowers (242.71 μg/g dw.). The most common phenolics were 4-hydroxybenzoic and salicylic acids, kaempferol-3-glucoside-7-rhamnoside, kaempferol-3-rutinoside and the rare narcissoside, which was present in almost all morphotic parts. The stem extract had the highest antioxidant activity and total phenolic content (611.86 mg/100 g dw.), whereas flower extract exerted the most potent antihyaluronidase effect (IC50 = 84.67 µg/mL; control-quercetin: IC50 = 514.28 μg/mL). Phytochemical analysis of the flower extract led to the isolation of two triterpene saponins that were shown to be strong hyaluronidase inhibitors (IC50 = 33.77 and 168.15 µg/mL; control-escin: IC50 = 307.38 µg/mL). This is the first report on the presence of phenolics and saponins in A. sagittata. The results suggest that both groups of metabolites may contribute to the overall activity of this plant species.

Integrated systematic pharmacology analysis and experimental validation to reveal the mechanism of action of Semen aesculi on inflammatory bowel diseases. JOURNAL OF ETHNOPHARMACOLOGY 2022; 298:115627. [PMID: 35985613 DOI: 10.1016/j.jep.2022.115627] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/06/2022] [Revised: 07/02/2022] [Accepted: 08/06/2022] [Indexed: 06/15/2023]
Abstract
BACKGROUND AND ETHNOPHARMACOLOGICAL RELEVANCE Semen aesculi (SA), a traditional Chinese herb, has been used in the treatment of gastrointestinal disease for thousands of years. The escin was the main components of SA. A growing number of research showed that escin has a wide range of pharmacological activities in intestinal barrier dysfunction. AIM OF THE STUDY Inflammatory bowel diseases (IBD) are an idiopathic disease of the intestinal tract with the hallmark features of mucosal inflammation and loss of barrier function. The theory of traditional Chinese medicine (TCM) suggests that SA plays a potential role in protecting the gastrointestinal diseases. The present study aimed to explore the effects of SA on the intestinal barrier under existing inflammatory conditions and elucidate underlying mechanisms. MATERIALS AND METHODS The bioactive components of SA and their predicted biological targets were combined to develop a compound target pathway network. It is used to predict the bioactive components, molecular targets, and molecular pathways of SA in improving IBD. The ingredients of SA were extracted by decoction either in water and ethanol and separated into four fractions (AE, EE, PEE and PCE). The effects of extractions were evaluated in the lipopolysaccharide (LPS)-induced RAW264.7 macrophages cell model, LPS-induced intestinal barrier injury model and imodium-induced constipation model. The high-performance liquid chromatography (HPLC) analysis was performed to identify the bioactive components. RESULTS The compound-target pathway network was identified with 10 bioactive compounds, 166 IBD-related targets, and 52 IBD-related pathways. In LPS-induced RAW264.7 cells, PEE and PCE significantly decreased nitric oxide (NO) production and TNF-α level. In mice, PEE and PCE administration improved intestinal barrier damage, increased intestinal motility, reduced levels of TNF-α and diamine oxidase (DAO). Furthermore, PEE and PCE administration not only decreased expression of p-Akt, p-IκBα, nuclear p-p65, and TNF-α level, but also increased expression of the zonula occludin-1 (ZO-1) in LPS-induced intestinal barrier injury model. The escin content of AE, EE, PEE and PCE gradually increased with an increase of the bioactivity. CONCLUSIONS Escin was the main bioactive components of SA. The effects of SA on IBD were mediated by repairing the intestinal barrier and promoting intestinal motility. The mechanism of action of SA is related to inhibiting the Akt/NF-κB signaling pathway in intestinal tissue, at least, in part. Our results provide a scientific basis for further exploring the mechanisms involved in the beneficial effects of SA in IBD.

Aescin Protects against Experimental Benign Prostatic Hyperplasia and Preserves Prostate Histomorphology in Rats via Suppression of Inflammatory Cytokines and COX-2. Pharmaceuticals (Basel) 2022; 15:ph15020130. [PMID: 35215244 PMCID: PMC8880638 DOI: 10.3390/ph15020130] [Citation(s) in RCA: 11] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/14/2021] [Revised: 01/19/2022] [Accepted: 01/19/2022] [Indexed: 02/07/2023] Open
Abstract
Background: Benign prostatic hyperplasia (BPH) is the most common urogenital condition in aging males, while inflammation and tissue proliferation constitute the main pathophysiological factors. The adverse effects of currently available BPH medications limit patient compliance. We tested the protective effect of aescin against the development of BPH in rats. Methods: A total of 18 male Wistar rats were divided into 3 groups: control (sesame oil 1 mL/kg, s.c.); BPH (testosterone oenanthate 3 mg/kg, s.c., in sesame oil), and BPH-aescin rats (testosterone oenanthate 3 mg/kg, s.c. + aescin 10 mg/kg/day, p.o.). All treatments continued for 4 weeks. Serum and prostatic samples were harvested for biochemical and histopathological examination. Results: Induction of BPH by testosterone increased the prostate weight and prostate weight index, serum testosterone, prostate expression of inflammatory (IL-1β, TNF-α, and COX-2), and proliferative markers (PCNA and TGF-β1). Concurrent treatment with aescin decreased the testosterone-induced increase in prostatic IL-1β, TNF-α, and COX-2 expression by 47.9%, 71.2%, and 64.4%, respectively. Moreover, aescin reduced the prostatic proliferation markers TGF-β1 and PCNA by 58.3% and 71.9%, respectively, and normalized the prostate weight. Conclusion: The results of this study showed, for the first time, that aescin protected against the development of experimental BPH in rats via its anti-inflammatory and antiproliferative effects. These findings warrant further studies to clinically repurpose aescin in the management of BPH.

Abstract
BACKGROUND The aim of this study was to evaluate the effect of a single early administration of dexamethasone and escin after loss of signal (LOS) during a neuromonitored total thyroidectomy. METHODS A retrospective analysis of results concerning consecutive patients undergoing total thyroidectomy was performed. Patients included in the study were divided into two groups: Group 1 for which a "wait and see" strategy was used; Group 2, receiving dexamethasone and escin immediately after LOS detection. RESULTS Overall 37 patients were included in Group 1 and 35 in Group 2. LOS recovery occurring in 29.7% of cases (n. 11) versus 65.7% (n. 23) respectively (p < 0.001). Postoperative fibrolayngoscopy for patients without LOS recovery showed normal cord function in 4 out of 26 cases (15.4%) in Group 1 and in 7 out of 12 (58.3%) in Group 2 (p < 0.001). CONCLUSIONS The early administration of dexamethasone and escin after LOS detection may achieve greater EMG signal recovery than a "wait and see" strategy.
