Abstract
Licochalcone B (LicB), a chalcone derived from Glycyrrhiza uralensis and Glycyrrhiza glabra, has received considerable attention due to its diverse pharmacological properties. Accumulated data indicates that LicB has pharmacological effects that include anti-cancer, hepatoprotective, anti-inflammatory, and neuroprotective properties. The action mechanism of LicB has been linked to several molecular targets, such as phosphoinositide 3-kinase/Akt/mammalian target of rapamycin, p53, nuclear factor-κB, and p38, and the involvements of caspases, apoptosis, mitogen-activated protein kinase-associated inflammatory pathways, and anti-inflammatory nuclear factor erythroid 2-related factor 2 signaling pathways highlight the multifaceted therapeutic potential of LicB. This review systematically updates recent findings regarding the pharmacological effects of LicB, and the mechanistic pathways involved, and highlights the potential use of LicB as a promising lead compound for drug discovery.

NAUNYN-SCHMIEDEBERG'S ARCHIVES OF PHARMACOLOGY 2024; 397:4247-4262. [PMID: 38078919 DOI: 10.1007/s00210-023-02863-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/20/2023] [Accepted: 11/19/2023] [Indexed: 05/23/2024]
Abstract
Licochalcone A (Lico A), a flavonoid found in licorice, possesses multiple pharmacological activities in modulating oxidative stress, glycemia, inflammation, and lipid metabolism. This study aimed to explore the potential mechanism of Lico A in mitigating ferroptosis associated with doxorubicin-induced cardiotoxicity (DIC). Initially, network pharmacology analysis was applied to identify the active components present in licorice and their targeted genes associated with DIC. Subsequently, to assess the role of Lico A in a DIC mouse model, electrocardiograms, myocardial injury markers, and myocardial histopathological changes were measured. Additionally, cell viability, reactive oxygen species (ROS), ferrous iron, glutathione/glutathione disulfide (GSH/GSSG), and malondialdehyde (MDA) were measured in the cell model as hallmarks of ferroptosis. Finally, the PI3K/AKT/MDM2/p53 signaling pathway and ferroptosis-related proteins were measured in vitro and in vivo. Bioinformatics results revealed that 8 major compounds of licorice, including Lico A, primarily regulated targets such as p53 and the PI3K/AKT signaling pathways in DIC. In the mouse model of DIC, Lico A significantly ameliorated serum biomarkers, histopathology, and electrocardiogram abnormalities. Pretreatment with Lico A enhanced the viability of H9C2 cells treated with doxorubicin. Furthermore, Lico A administration resulted in decreased levels of ROS, ferrous iron, and MDA and increased levels of GSH/GSSG. At the protein level, Lico A increased the phosphorylation of PI3K/AKT/MDM2, reduced p53 accumulation, and induced the upregulation of SLC7A11 and GPX4 expression. However, selective inhibition of PI3K/AKT and plasmid-based overexpression of p53 significantly abolished the anti-ferroptosis functions of Lico A. In conclusion, Lico A attenuates DIC by suppressing p53-mediated ferroptosis through activating PI3K/AKT/MDM2 signaling.

PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2024; 126:155409. [PMID: 38342018 DOI: 10.1016/j.phymed.2024.155409] [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: 09/06/2023] [Revised: 10/30/2023] [Accepted: 02/01/2024] [Indexed: 02/13/2024]
Abstract
BACKGROUND Flavonoids are extensively present in fruits, vegetables, grains, and medicinal plants. Myocardial ischemia and reperfusion (MI/R) comprise a sequence of detrimental incidents following myocardial ischemia. Research indicates that flavonoids have the potential to act as cardioprotective agents against MI/R injuries. Several specific flavonoids, e.g., luteolin, hesperidin, quercetin, kaempferol, and puerarin, have demonstrated cardioprotective activities in animal models. PURPOSE The objective of this review is to identify the cardioprotective flavonoids, investigate their mechanisms of action, and explore their application in myocardial ischemia. METHODS A search of PubMed database and Google Scholar was conducted using keywords "myocardial ischemia" and "flavonoids". Studies published within the last 10 years reporting on the cardioprotective effects of natural flavonoids on animal models were analyzed. RESULTS A total of 55 natural flavonoids were identified and discussed within this review. It can be summarized that flavonoids regulate the following main strategies: antioxidation, anti-inflammation, calcium modulation, mitochondrial protection, ER stress inhibition, anti-apoptosis, ferroptosis inhibition, autophagy modulation, and inhibition of adverse cardiac remodeling. Additionally, the number and position of OH, 3'4'-catechol, C2=C3, and C4=O may play a significant role in the cardioprotective activity of flavonoids. CONCLUSION This review serves as a reference for designing a daily diet to prevent or reduce damages following ischemia and screening of flavonoids for clinical application.

Abstract
Cytosolic DNA activates the STING (stimulator of interferon genes) signaling pathway to trigger interferon and inflammatory responses that protect against microbial infections and cancer. However, Aicardi-Goutières syndrome (AGS) persistently activates the STING signaling pathway, which can lead to severe autoimmune diseases. We demonstrate herein that Licochalcone B (LicoB), the main component of traditional licorice, is an inhibitor of the STING signaling pathway. We observed that LicoB inhibited the activation of the STING signaling pathway in macrophages. Mechanically, LicoB affected the STING-TBK1-IRF3 signal axis and inhibited the activation of the STING downstream signaling pathway. Furthermore, LicoB inhibited the increase in type I interferon levels in mice induced by the STING agonist CMA. LicoB significantly reduced systemic inflammation in Trex1-/- mice. Our results show that LicoB, a STING signaling pathway inhibitor, is a promising candidate for the treatment of diseases related to STING signaling pathway activation.

Abstract
Myocardial ischemia-reperfusion (I/R) injury triggers several cell death types, including apoptosis, autophagy, and ferroptosis. Licochalcone A (LCA), a natural flavonoid compound isolated from the root of Glycyrrhiza glabra, has been demonstrated to exert potential pharmacological benefits, such as antioxidant, antitumor, and anti-inflammatory activities. The present study aimed to investigate the involvement of ferroptosis in the pathogenesis of I/R and determine whether LCA can inhibit ferroptosis to prevent the myocardial I/R injury in rats. The effects of LCA on myocardial I/R injury were detected by examining the left ventricular-developed pressure and triphenyltetrazolium chloride staining. We conducted Western blotting analyses, ELISA assay, and quantitative real-time PCR to determine the levels of ferroptosis-related molecules. To demonstrate the cardioprotective effect of LCA in vitro, H9c2 and primary neonatal rat cardiomyocytes were co-treated with ferroptosis inducers (erastin, RSL3, or Fe-SP) and LCA for 16 and 24 h. Our ex vivo study showed that LCA increased the cardiac contractility, and reduced the infarct volume and ferroptosis-related biomarkers in rat hearts after I/R. Moreover, LCA reduced the levels of ferroptosis inducers-induced reactive oxygen species generation, lipid peroxidation, and ferroptosis-related biomarkers in cultured H9c2 cells and cardiomyocytes. LCA also reduced the Fe-SP-increased nuclear factor erythroid 2-related factor 2 and heme oxygenase-1 protein levels in cultured cardiomyocytes. In the present study, we showed that the LCA-induced cardioprotective effects in attenuating the myocardial I/R injury were correlated with ferroptosis regulation, and provided a possible new therapeutic strategy for prevention or therapy of the myocardial I/R injury.

Abstract
ABSTRACT Myocardial infarction is among the leading causes of mortality. Menaquinone-4 (MK-4), a vitamin K2 analog, might play a role in rescuing cardiac ischemia/reperfusion (I/R) injury. This work aimed to discover the potential cardioprotective role of MK-4 against myocardial I/R injury in rats. Thirty-two rats were categorized into 3 groups: (I/R) control group: subjected to I/R protocol (received vehicle), MK-4 preconditioning group: MK-4 infusion for 20 minutes before the I/R protocol, and MK-4 postconditioning group: MK-4 infusion for 20 minutes at the start of the reperfusion phase. The hearts were placed in the Langendorff apparatus, and the left ventricular developed pressure (LVDP), heart rate (HR), + (LV dP/dt) max, - (LV dP/dt) max, and Tau were calculated. The necrotic mass was determined by staining it with nitro blue tetrazolium. Creatine kinase-MB (CK-MB), lactate dehydrogenase (LDH), tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), and C- reactive protein (CRP), as well as cardiac superoxide dismutase (SOD), nitric oxide (NOx), malondialdehyde (MDA), and glutathione (GSH) levels were all evaluated. MK-4 postconditioning significantly reduced myocardial infarct size; increased LVDP, + (LV dp/dt) max, - (LV dp/dt) max, and HR; reduced Tau, CK-MB, LDH, CRP, IL-6, TNF-α, MDA, and NOx levels; and increased SOD activity, whereas no significant difference in the GSH level was detected. In conclusion, these data imply that MK-4 may protect the heart from the consequences of I/R.

Abstract
Schisantherin A (Sch A) is a dibenzocyclooctadiene lignan monomer isolated from the fruit of Schisandra chinensis (Turcz.) Baill. (S. chinensis). At present, many studies have shown that Sch A has a wide range of pharmacological effects, including its anti-Parkinson and anti-inflammatory effects and ability to protect the liver, protect against ischemia-reperfusion (I/R) injury, suppress osteoclast formation, and improve learning and memory. Its mechanism may be related to the antioxidant, anti-inflammatory, and antiapoptotic properties of Sch A through the MAPK, NF-κB, AKT/GSK3β, and PI3K/AKT pathways. This is the first review of the recent studies on the pharmacological mechanism of Sch A.

Abstract
BACKGROUND Investigating anti-oxidant therapies that lead to the diminution of oxidative injury is priority in clinical. We herein aimed to explore whether and how Licochalcone B (Lico B) act as an anti-oxidant in the stroke model. METHODS Middle cerebral artery occlusion (MCAO) was constructed as stroke model and exposed to various doses of Lico B. Behavioral tests and neurological behavior status were detected for neurological function examination. Histological staining was used for evaluating cerebral injury, and neuronal apoptosis or damage. Levels of oxidative stress and inflammation were also assessed by biochemical analysis and expression analysis. Nrf2 knockdown induced by lentiviral vector was used for the research on mechanism. RESULTS Lico B had improvement effects on cerebral infarction size, memory impairments, and neurological deficits after MCAO. Histological evaluation also revealed the amelioration of neuronal injury and apoptosis by Lico B, along with down-regulation of apoptosis-related proteins. Additionally, Lico B rescued the down-regulation of BDNF and NGF after MCAO. Moreover, Lico B suppressed the oxidative stress and inflammation, manifesting as the enhancement of SOD, GSH and IL-4, but the decline of MDA, iNOS, and TNF-α. Finally, Nrf2 knockdown reversed the Lico B-caused improvement in neuronal injury, apoptosis and oxidative stress levels. CONCLUSIONS The present study revealed the neuroprotective effects of Lico B in MCAO rats. Importantly, we proposed a potential mechanism that Lico B activated the Nrf2 pathway, thereby acting as anti-oxidant to attenuate neuronal injury and apoptosis after stroke. The proposed mechanism provided an encouraging possibility for anti-oxidant therapy of stroke.

Abstract
Chinese herbal medicines (CHM) are frequently used to treat different types of inflammatory diseases and 15-Lipoxygenase (15-LOX) is a critical target enzyme for treating various inflammatory diseases. In this study, natural 15-LOX inhibitors were identified in CHM using an approach of virtual screening combined with the biological assays. First, an in-house Chinese medicine database containing 360 compounds was screened using a virtual screening approach based on pharmacophore and molecular docking to uncover several novel potential 15-LOX inhibitors. Secondly, the inhibitory effect of virtual screening hits against the 15-LOX enzyme was validated in an in vitro enzyme inhibition assay. Then, a tumor necrosis factor-α (TNF-α) release assay was carried out to explore the anti-inflammatory response of the active compounds. Furthermore, molecular dynamics (MD) simulation and binding free energy calculation were applied to analyze the process of inhibitors binding and also compared the mode of binding of the inhibitors by using the Molecular Mechanics-Generalized Born Surface Area (MM/GBSA) method. Finally, licochalcone B and eriodictyol were confirmed as inhibitors of the 15-LOX enzyme with IC50 values of 9.67 and 18.99 μM, respectively. In vitro cell-based assay showed that licochalcone B and eriodictyol inhibited the release of TNF-α factor in RAW264.7 cells stimulated by lipopolysaccharides (LPS) in a dose-dependent manner. Molecular dynamics and binding free energy analysis showed that the two 15-LOX-ligand systems immediately attained equilibrium with almost 1 Å fluctuation, the calculated binding free energies were found around -18.89 and -12.96 kcal/mol for licochalcone B and eriodictyol, respectively. Thr412, Arg415, Val420, Thr429, Ile602 and Trp606 were the main amino acid residues for the inhibition of 15-LOX enzyme activity. The current study confirms that licochalcone B and eriodictyol are 15-LOX inhibitors and can suppress the release of the TNF-α factor in RAW264.7 cells stimulated by LPS, thus providing a basis for the follow-up research and development for 15-LOX inhibitors.

Abstract
This study aimed to investigate the antihyperlipidemic and anti-inflammatory effect of zingiberene (ZBN) on isoproterenol-(ISO) induced myocardial infarction in rats. ZBN (10 mg/kg b.wt.) was orally administered to rats for 21 days and ISO (85 mg/kg b.wt.) was subcutaneously injected into the rats at 24 h intervals for the last 2 consecutive days. We observed increased serum creatine kinase, creatine kinase-MB, cardiac troponin T, and I levels in ISO-treated MI rats. Conversely, ZBN oral administration significantly prevented in cardiac marker enzyme activities in ISO-mediated rats. We also noticed that ZBN oral administration prevented ISO-induced expression of lipid peroxidative markers, total cholesterol, triglycerides, phospholipids, free fatty acids, very-low-density lipoprotein cholesterol (VLDL-C), low-density lipoprotein cholesterol (LDL-C) to the normal basal level. Furthermore, ZBN restored ISO-mediated antioxidant status, increased level of high-density lipoprotein cholesterol (HDL-C), and tissue phospholipids to the near-normal levels. Besides, ZBN pre-treatment significantly reduced the level of inflammatory markers (TNF-α, IL-6, NF-κB, and IL-1β) in ISO-induced MI in rats. We noticed that ZBN pretreatment inhibited the pro-apoptotic proteins Bax and cytochrome c and increased the Bcl-2 expression in ISO induced rats. The gene expression profiling by qRT-PCR array illustrates that ZBN treatment prevents the ISO mediated activation of cardiac markers, inflammatory, and fibrosis-related genes in the heart tissue. Taken together, pre-treatment with ZBN attenuated ISO-induced MI resolved exhibits the anti-inflammatory and antiapoptotic effect.

Abstract
OBJECTIVES Cardiac transplantation is an effective treatment for advanced heart disease and protection of the donor organ is directly associated with post-transplantation outcomes. Cardioplegic strategies intend to protect the donor heart against ischemic injury during transplantation procedures. In our study, the effects of three different cardioplegia solutions were evaluated in a rat heart donor model in terms of cellular base. Design. Cardioplegia solutions as St. Thomas, del Nido or Custodiol were administered to male Wistar albino rats until cardiac arrest. Arrested hearts were excised and incubated in cold cardioplegia solutions for 4 h. Organ bath experiments were performed using the right ventricular free wall strips of the heart tissues. ATP, sialic acid, TNF-α levels and MMP-9 activities were measured in heart tissues. Incubation media were also used to measure TNF-α and troponin-I levels following organ baths experiments. Results. Custodiol administration led to reduced myocardial contraction (p < .05), decreased ATP levels (p < .001) and increased both TNF-α levels (p < .05), and MMP-9 activity (p < .05). Additionally, troponin-I and TNF-α levels in media were significantly increased (p < .05), TNF-α levels were positively correlated with MMP-9 activities (r = .93, p = .007) and negatively correlated with ATP levels (r = -.91, p = .01) in the Custodiol group. Also, MMP-9 activities were negatively correlated with ATP levels (r = -.90, p = .01) Conclusion. Custodiol cardioplegia cannot prevent functional and cellular damage in donor heart tissue. St. Thomas or del Nido cardioplegia could result in superior functional and biochemical improvement during transplantation procedures. In this respect, these cardioplegic solutions may be more advantageous as cellular and functional.

Abstract
Background The ischemia-reperfusion (I/R) injury of skin flap is a complex pathophysiological process involving many cells and factors. Although endoplasmic reticulum (ER) stress-induced cell apoptosis and inflammatory response are of immense importance in the skin flap ischemia, the treatment for I/R injury induced by ER stress is barely reported. Methods Healthy male Wister rats were randomly divided into three groups: sham-operated group, I/R model group and I/R + LXA4 group. I/R-induced injury in skin flaps with or without pre-treatment of Lipoxin A4 (LXA4, 100 µg/kg) was tested by using HE and TUNEL staining. Related factors associated with oxidative stress, apoptosis, inflammatory response, and ER stress were tested by ELISA, biochemical assay, and western blotting, respectively. Results Our results showed that LXA4 treatment significantly promotes skin flap survival and attenuates I/R injury by inhibiting oxidative stress, apoptosis, and inflammatory factor release, evidenced by the decreased expression of malondialdehyde (MDA), lactate dehydrogenase (LDH), NF-κBp65, tumor necrosis factor α (TNF-α), ET, active Caspase-3 and Bax and up-regulated superoxide dismutase (SOD), glutathione (GSH) level and Bcl-2 expression. Moreover, LXA4 treatment also reverses the increased expression of GRP78, p-PERK, p-eIF2α, ATF4, and CHOP induced by I/R injury. Conclusions In conclusion, we showed that ER stress causes cell apoptosis and inflammatory response, resulting in the skin flaps injury. LXA4 exhibits a protective effect on skin flaps against I/R injury through the inhibition of ER stress.

Abstract
This study was performed to evaluate the role of electroacupuncture on kidney 1 (Ki1) acupoint to prevent the heart and brain injury following ischemia/reperfusion of both kidneys. 24 Sprague Dawley rats were randomly assigned into four equal groups. In the treatment 1 group, following anesthesia, acupuncture needles were inserted on Ki1 on the palm of both hindlimbs and connected to electroacupuncture unit for a 3.00 Hz direct current, 1 hr before surgery until the end of surgery. In treatment two groups, the electroacupuncture was also performed 48 and 24 hr before the operation, with the same protocol as treatment 1. Control 1 and control 2 groups had the same procedures like the treatment ones, except for acupuncture. Immediately after reperfusion, the samples of brains and hearts were taken and prepared for microscopic examination. Histopathological study of the heart in the control and treatment groups showed the breakage of myofibrils, hyaline necrosis, edema and disorganization of myocytes. The severity of cardiac lesions was decreased in both treatment groups in comparison with the controls. Brain in control and treatment groups showed ischemic necrosis, disorganization of the neurons in the hippocampus, and edema. The severity of lesions was reduced in the treatment groups and showed a significant difference between the control and treatment 1. It could be concluded that electroacupuncture on the Ki1 point could reduce the severity of damages induced by renal ischemia/reperfusion in the remote organs of the heart and brain.

Abstract
Licorice is extensively applied in food as well as herbal medicine across the world, possessing a substantial share in the global market. It has made great progress in chemical and pharmacological research in recent years. Currently, Glycyrrhiza uralensis Fisch., Glycyrrhiza inflata Bat., and Glycyrrhiza glabra L. were officially used as Gan-Cao according to the Chinese Pharmacopoeia. Accumulating evidence demonstrated three varieties of licorice have their own special compounds except for two quality markers set by Pharmacopoeia, providing great possibility for better understanding their characteristics, evaluating quality of each species and studying biosynthesis mechanisms of species-specific compounds. As a special "guide drug" in clinic, licorice plays an important role in Chinese herbal formulas. The interaction between licorice with other ingredients and their metabolism in vivo should also be taken into consideration. In addition, draft genome annotation, and success of the final step of glycyrrhizin biosynthesis have paved the way for biosynthesis of other active constituents in licorice, a promising beginning of solving source shortage. Accordingly, we comprehensively explored the nearly 400 chemical compounds found in the three varieties of licorice so far, systematically excavated various pharmacological activities, including metabolism via CYP450 system in vivo, and introduced the complete biosynthesis pathway of glycyrrhizin in licorice. The review will facilitate the further research toward this herbal medicine.

Abstract
Apurinic/apyrimidinic endonuclease 1/redox factor-1 (APE1/Ref-1) is a ubiquitous multifunctional protein required in the DNA base excision repair pathway and a noteworthy reducing-oxidizing factor that regulates the activity of various transcription factors. Cyclin-dependent kinases (CDKs) assume a key role in directing the progression of the cell- cycle. The present study evaluated the synergistic efficacy of using licochalcone B (LCB) and fullerene C60 (FnC60) nanoparticles against diethylnitrosamine (DEN)-induced hepatocarcinoma in rats and relevant signaling pathways, with APE1/Ref-1 and CDK-4, as novel anti-cancer- targeting. LCB alone and in combination with FnC60 significantly decreased DNA fragmentation, oxidative DNA damage (8-hydroxy-2'-deoxyguanosine levels), APE1/Ref-1, CDK-4, retinoblastoma, B- cell lymphoma-2 (Bcl-2), B-cell lymphoma-xL (Bcl-xL), and β-arrestin-2 mRNA expression, and APE1/Ref-1 and CDK-4 protein expression. In contrast, these treatments significantly increased the expression of protein 53 (p53), Bcl-2-associated X protein (Bax), and caspase-3. These data suggest that LCB either alone or in combination with FnC60 elicited significant protective effects against DEN-induced hepatocarcinogenesis, which may have occurred because of the regulation of enzymes involved in DNA repair and cell-cycle control at S phase progression as well as the induction of apoptosis at the gene and protein expression levels. Furthermore, FnC60 potentiated the effect of LCB at the molecular level, possibly through targeting of cancerous cells.

Abstract
BACKGROUND Epidermal growth factor receptor (EGFR) gene alterations are associated with sensitization to tyrosine kinase inhibitors such as gefitinib in lung cancer. Some patients suffering from non-small cell lung cancer (NSCLC) have difficulty in treating the cancer due to resistance acquired to gefitinib with MET amplification. Therefore EGFR and MET may be attractive targets for lung cancer therapy. PURPOSE This study aimed to investigate the anti-cancer activity of Licochalcone (LC)B extracted from Glycyrrhiza inflata, in gefitinib-sensitive or gefitinib-resistant NSCLC cells, and to define its mechanisms. STUDY DESIGN We investigated the mechanism of action of LCB by targeting EGFR and MET in human NSCLC cells. METHODS We used the HCC827 and HCC827GR lines as gefitinib-sensitive and -resistant cells respectively, and determined the effects of LCB on both, by performing cell proliferation assay, flow cytometry analysis and Western blotting. Targets of LCB were identified by pull-down/kinase assay and molecular docking simulation. RESULTS LCB inhibited both EGFR and MET kinase activity by directly binding to their ATP-binding pockets. The ability of this interaction was verified by computational docking and molecular dynamics simulations. LCB suppressed viability and colony formation of both HCC827 and HCC827GR cells while exhibiting no cytotoxicity to normal cells. The induction of G2/M cell-cycle arrest and apoptosis by LCB was confirmed by Annexin V/7-AAD double staining, ER stress and reactive oxygen species induction, mitochondrial membrane potential loss and caspase activation as well as related-proteins regulation. Inhibition of EGFR and MET by LCB decreased ERBB3 and AKT axis activation. CONCLUSION We provide insights into the LCB-mediated mechanisms involved in reducing cell proliferation and inducing apoptosis in NSCLC cells. This occurs through dual inhibition of EGFR and MET in NSCLC cells regardless of their sensitivity or resistance to gefitinib. LCB may be a promising novel therapeutic medicine for gefitinib-sensitive or resistant NSCLC treatment.

Abstract
BACKGROUND Myocardial injury due to ischemia-reperfusion (IR) is aggravated in diabetes which is associated with oxidative stress. Alleviating oxidative stress via use of antioxidants has been shown to be effective at minimizing myocardial cell death and improving cardiac function. The aim of the present study was to evaluate the cardioprotective effect of phloroglucinol against myocardial reperfusion injury (MRI) in diabetic rats. METHODS Diabetes was induced in female rats with streptozotocin (50 mg/kg). The diabetic rats were orally treated with phloroglucinol (100 and 200 mg/kg daily for 28 days). After treatment the hearts were isolated and mounted on a Langendorff apparatus. The hearts were subjected to 15 minutes of IR to induce myocardial damage. Cardiac functions including heart rate (HR), resting and developed tension, and rate of change of contraction (+dP/dt max) were recorded. Cardiac injury biomarkers lactate dehydrogenase (LDH) and creatine kinase (CK-MB) were measured in the heart perfusate. Levels of the antioxidant enzymes reduced glutathione (GSH) and malondialdehyde (MDA) were measured. Hematoxylin and eosin (H&E) staining was also performed. RESULTS After IR injury, a decrease in HR and +dP/dt max in hearts from diabetic rat was seen compared to healthy rat hearts, which was reversed by phloroglucinol treatment. Myocardial infarct size, measured by H&E staining, was increased in diabetic rats compared to healthy rats and an increase in the activity of LDH and CK-MB in the heart perfusate in diabetic rats was decreased by phloroglucinol treatment. An increase in MDA levels and a decrease in levels of antioxidant enzymes were observed in diabetic rats, which was reversed with phloroglucinol treatment. CONCLUSION Phloroglucinol treatment has potential therapeutic promise in the treatment of MRI in diabetes.

Abstract
A multi-component solution, containing α-ketoglutaric acid (α-KG), 5-hydroxymethylfurfural (5-HMF), N-acetyl-seleno-L-methionine (NASeLM), and N-acetyl-L-methionine (NALM) as active ingredients, has been tested considering its supposed antioxidative effect with respect to heart transplantations. Oxidative stress was induced on isolated rat hearts through occlusion of a coronary artery and in chicken heart tissue through hydrogen peroxide. Both heart types were analyzed and the oxidative stress markers malondialdehyde (MDA) and carbonyl proteins (CPs) were determined via HPLC/UV-Vis. In both approaches, it was found that treatment with the multi-component solution led to a lower amount of MDA and CPs compared to a negative control treated with Krebs-Ringer solution (KRS). Further investigation on chicken heart tissue identified α-KG as antioxidative component in these experiments. However, numerous factors like arrhythmia, vessel dilatation, and minimization of oxidative stress effects play an important role for successful transplantation. Therefore, the investigated multi-component solution might be a novel approach against oxidative stress situations, for example at ischemia reperfusion injury during heart transplantations.

Abstract
The present study explored the molecular mechanism by which licochalcone B induces the cell cycle arrest and apoptosis in human hepatoma cell HepG2. Initial extraction and identification were performed by HPLC, UPLC-TOF-MS/MS, and NMR analysis, respectively. Licochalcone B inhibited the HepG2 growth with IC50 (110.15 μM) after 24 h, caused morphological distortion, and seized the cell cycle in the G2/M phase (cell arrest in G2/M:43.1 ± 2.2% for 120 μM versus 23.7 ± 1.2% for control), as well as induced apoptosis and intracellular ROS generation. Furthermore, exposure to licochalcone B markedly affected the cell cycle (up/down regulation) at mRNA and protein levels. Apoptosis was induced through the activation of receptor-mediated and mitochondrial pathways. The inhibition of Caspase 8 and Caspase 9 proteins abolished the licochalcone B induced apoptosis. The present work suggested that licochalcone B may further be identified as a potent functional food component with specific health benefits.

The Role of Traditional Chinese Medicine in the Regulation of Oxidative Stress in Treating Coronary Heart Disease. OXIDATIVE MEDICINE AND CELLULAR LONGEVITY 2019; 2019:3231424. [PMID: 30918578 PMCID: PMC6409025 DOI: 10.1155/2019/3231424] [Citation(s) in RCA: 39] [Impact Index Per Article: 7.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 11/24/2018] [Revised: 01/19/2019] [Accepted: 02/04/2019] [Indexed: 02/06/2023]
Abstract
Oxidative stress has been closely related with coronary artery disease. In coronary heart disease (CHD), an excess of reactive oxygen species (ROS) production generates endothelial cell and smooth muscle functional disorders, leading to a disequilibrium between the antioxidant capacity and prooxidants. ROS also leads to inflammatory signal activation and mitochondria-mediated apoptosis, which can promote and increase the occurrence and development of CHD. There are several kinds of antioxidative and small molecular systems of antioxidants, such as β-carotene, ascorbic acid, α-tocopherol, and reduced glutathione (GSH). Studies have shown that antioxidant treatment was effective and decreased the risk of CHD, but the effect of the treatment varies greatly. Traditional Chinese medicine (TCM) has been utilized for thousands of years in China and is becoming increasingly popular all over the world, especially for the treatments of cardiovascular diseases. This review will concentrate on the evidence of the action mechanism of TCM in preventing CHD by modulating oxidative stress-related signaling pathways.

Abstract
Hypoxia induces myocardial injury through the activation of inflammatory and oxidative processes. The pivotal role of the renin angiotensin system (RAS) in the pathogenesis of cardiovascular diseases has been firmly established in clinical trials and practice; in fact many experimental and clinical data have highlighted that its inhibition has a cardioprotective role. Activated RAS also stimulates inflammation directly inducing proinflammatory and oxidative gene expression. This study aimed to investigate the protective role of a pre-treatment (10 and 100 μM) with irbesartan on injury induced by 24 h of hypoxia in HL-1 cardiomyocytes; in particular, we have analyzed the natriuretic peptide (BNP) expression, a biomarker able to modulate inflammatory reaction to cardiac injury and some markers involved in oxidative stress and inflammation. Our results demonstrated that a pre-treatment with 100 μM irbesartan significantly increased SOD activity and catalase expression of 15 and 25%, respectively, compared to hypoxic cells (P<0.05). On the other hand, it was able to reduce the release of peroxynitrite and iNOS protein expression of 20 and 50% respectively (P<0.05). In addition irbesartan exerts an anti-inflammatory activity reducing Toll-like receptors (TLRs)-2 and -4 mRNA expression, TNF-alpha expression and activity (20%) and increasing the expression of the cytokine IL-17 (40%) (P<0.05 vs hypoxia). Our findings also showed that BNP induced by ischemia was significantly and in a concentration-dependent manner reduced by irbesartan. The findings of our study demonstrated that the AT1 receptor antagonist irbesartan exerts a protective role in an in vitro hypoxic condition reducing oxidative stress and inflammation.

Abstract
Traumatic brain injury (TBI) poses a serious threat to human health. TBI has a high mortality rate, resulting in a great burden on the affected individual's family as well as society as a whole. The incidence of craniocerebral fractures continues to rise as both the economy and transportation options grow, making it imperative that the mortality and disability rate of craniocerebral trauma be reduced. Nur77 is a transcription factor of the nuclear receptor superfamily. Following stimulation of extracellular apoptosis, Nur77 is involved in a variety of diseases as a powerful pro-apoptotic molecule. Here, we determined the effect and mechanism of Nur77 in TBI-induced nerve cell apoptosis in vitro and in vivo. We found that Nur77 and Bcl-2 protein expression increased as nerve cell apoptosis increased in TBI tissues. Furthermore, inhibition of Nur77 improved nerve cell injury by regulation of Bcl-2 and downstream pathways in vitro and in vivo.

J Surg Res 2018; 232:442-449. [PMID: 30463755 DOI: 10.1016/j.jss.2018.06.042] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/09/2018] [Revised: 05/18/2018] [Accepted: 06/14/2018] [Indexed: 01/18/2023]
Abstract
BACKGROUND Adenosine A2B receptor (A2BAR) agonist reduces myocardial reperfusion injury by acting on inflammatory cells. Recently, a cardiosplenic axis was shown to mediate the myocardial postischemic reperfusion injury. This study aimed to explore whether the infarct-squaring effect of A2BAR agonist was primarily due to its action on splenic leukocytes. METHODS C57BL6 (wild type [WT]) mice underwent 40 min of left coronary artery occlusion followed by 60 min of reperfusion. A2BAR knockout (KO) and interleukin (IL)-10KO mice served as donors for splenic leukocytes. Acute splenectomy was performed 30 min before ischemia. The acute splenic leukocyte adoptive transfer was performed by injecting 5 × 106 live splenic leukocytes into splenectomized mice. BAY 60-6583, an A2BAR agonist, was injected by i.v. 15 min before ischemia. The infarct size (IS) was determined using 2,3,5-triphenyltetrazolium chloride and Phthalo blue staining. The expression of p-Akt and IL-10 was estimated by Western blotting. Immunofluorescence staining assessed the localization of IL-10 expression. RESULTS BAY 60-6583 reduced the myocardial IS in intact mice but failed to reduce the same in splenectomized mice, which had a smaller IS than intact mice. BAY 60-6583 reduced the IS in splenectomized mice with the acute transfer of WT splenic leukocytes; however, it did not protect the heart of splenectomized mice with the acute transfer of A2BRKO splenic leukocytes. Furthermore, BAY 60-6583 increased the levels of p-Akt and IL-10 in the WT spleen. Moreover, it did not exert any protective effect in IL-10KO mice. CONCLUSIONS A2BAR activation before ischemia stimulated the IL-10 production in splenic leukocytes via a PI3K/Akt pathway, thereby exerting anti-inflammatory effects that limited the myocardial reperfusion injury.

Abstract
The present study used an in vitro model of cold cardioplegia in isolated working rat hearts to evaluate the possible effects of two flavonoids, astragalin and dihydromyricetin, as adjuncts to histidine‑tryptophan‑ketoglutarate (HTK) cardioplegia. The following three groups of male Sprague Dawley rats were evaluated: The HTK group, treated with HTK alone; the HTK‑A group, treated with 10 µmol/l astragalin; and the HTK‑D group, treated with 10 µmol/l dihydromyricetin. Isolated rat hearts were perfused with Krebs‑Henseleit buffer for 30 min and incubated with the respective cardioplegic solution for 6 h at 4˚C. Subsequently, astragalin or dihydromyricetin was added to the cardioplegic solutions. Following 30 min of reperfusion, the left ventricular developed pressure (LVDP), maximum up/down rate of left ventricular pressure (±dp/dtmax) and heart rate were documented as indices of myocardial function using a physiological recorder. Myocardial infarct size (IS) was estimated using 2,3,5‑triphenyltetrazolium chloride staining. Lactate dehydrogenase (LDH) and creatine kinase (CK) levels were also determined to assess the degree of cardiac injury. Cardiomyocyte apoptosis analysis was performed using an in situ cell death detection kit. In addition, malondialdehyde (MDA), superoxide dismutase (SOD), interleukin‑6 (IL‑6), tumor necrosis factor‑α (TNF‑α), C‑reactive protein (CRP) levels, as well as the glutathione/glutathione disulfide (GSH/GSSG) ratio were determined and analyzed using ELISA kits. The protein levels of caspase‑9 and B‑cell lymphoma‑2 (Bcl‑2) were determined using western blot analysis. The results demonstrated that exposure to astragalin or dihydromyricetin significantly improved the recovery of LVDP (P<0.05 and P<0.01, respectively), the +dP/dtmax (P<0.05 for dihydromyricetin only) and the ‑dP/dtmax (P<0.05 and P<0.01, respectively), increased SOD levels (P<0.05 and P<0.01, respectively) and GSH/GSSG ratios (P<0.05), reduced myocardial IS (P<0.05 and P<0.01, respectively), decreased CK, LDH, IL‑6 (all P<0.05 and P<0.01, respectively), MDA (P<0.05), CRP (P<0.05) and TNF‑α levels (P<0.05 and P<0.01, respectively), increased Bcl‑2 levels (P<0.01) and decreased caspase‑9 levels (P<0.01). The results indicated that the addition of either flavonoid (particularly dihydromyricetin) to HTK enhances protection during ischemia, decreases myocardial dysfunction by enhancing anti‑inflammatory activities, attenuates myocardial oxidative injury and prevents apoptosis during ischemia/reperfusion.

Abstract
Licorice, an important herbal medicine, is derived from the dried roots and rhizomes of Glycyrrhiza genus plants. It has been widely used in food, pharmaceutical, tobacco, and cosmetics industries with high economic value. However, overexploitation of licorice resources has severely destroyed the local ecology. Therefore, producing bioactive compounds of licorice through the biotransformation and bioengineering methods is a hot spot in recent years. In this perspective, we comprehensively summarize the biotransformation of licorice constituents into high-value-added derivatives by biocatalysts. Furthermore, successful cases and the strategies for de novo biosynthesizing compounds of licorice in microbes have been summarized. This paper will provide new insights for the further research of licorice.

Abstract
The aim of this study is to investigate both the efficacy and mechanism of action of kaempferide (Kae) as a therapy for the treatment of cardiovascular disease. A rat model of myocardial ischemia/reperfusion (I/R) injury was established by ligation of the left anterior descending coronary artery for 30 min followed by a 2 h perfusion. In our study, we show that Kae remarkably improved cardiac function, alleviated myocardial injury via a decrease in myocardial enzyme levels, and attenuated myocardial infarct size in a dose-dependent manner. In addition, preconditioning treatment with Kae was found to significantly decrease serum TNF-α, IL-6, C-reactive protein (CRP), MDA, and ROS levels, while it was found to increase serum levels of SOD. Nuclear factor erythroid 2-related factor 2 (Nrf2) and cleaved caspase-3 expression levels were observed to be downregulated, while phospho-Akt (p-Akt) and phospho-glycogen synthase kinase-3β (p-GSK-3β) expression levels were upregulated. However, cotreatment with LY294002 (a PI3K inhibitor) or TDZD-8 (a GSK-3β inhibitor) was found to abolish the above cardioprotective effects observed with the Kae treatment. The data presented in this study provides evidence that Kae attenuates I/R-induced myocardial injury through inhibition of the Nrf2 and cleaved caspase-3 signaling pathways via a PI3K/Akt/GSK 3β-dependent mechanism.

Abstract
The cardiac ischemia-reperfusion (I/R) injury greatly influences the therapeutic effect and remains an urgent challenge in clinical therapy. Polypharmacology opens a new therapeutic opportunity to design drugs with a specific target for improving the efficacy. In this study, we first forecasted that Rosmarinic acid (RosA) could be used for the treatment of cardiovascular disease using text mining, chemometric and chemogenomic methods. Consistent with the effect of the positive drug (pioglitazone, PIO), we subsequently validated that RosA pretreatment could restore the decreased cardiac hemodynamic parameters (LVDP, ± dp/dtmin, ± dp/dtmax and CF), decreased the infarct size and the cardiomyocyte apoptosis in a rat model of cardiac I/R injury. Furthermore, RosA pre-treatment inhibited the levels of inflammatory cytokines (IL-6, TNF-α and CRP), up-regulated PPARγ expression and down-regulated NF-κB expression in myocardial tissue isolated from the rat model of I/R-induced myocardial injury. In addition, the effects of RosA were reversed by co-treatment with PPAR-γ inhibitor GW9662 and T0070907, respectively. These data suggest that RosA attenuates cardiac injury through activating PPARγ and down-regulating NF-κB-mediated signaling pathway, which inhibiting inflammation and cardiomyocyte apoptosis in a rat model of cardiac I/R injury.

Abstract
Perfusion of hearts with extracts of Ilex paraguariensis (IP/mate) appears to reduce ischemia/reperfusion (I/R) injury. To determine if oral consumption of IP/mate can provide similar cardioprotection, short-term consumption was investigated alone or in association with exercise in rats. Animals were grouped into control (C), IP/mate consumption (M), exercise (E), and exercise with mate (E+M). M and E+M groups consumed IP/mate (1 g·kg-1 body weight in 1 mL water) by gavage. E and E+M groups swam 7× per week for 30 min carrying an additional 5% of body weight. After 1 week, hearts were tested ex vivo to measure left ventricle developed pressure (LVDP), systolic and end diastolic pressure (LVSP/LVEDP), maximum velocity of contraction and relaxation (dP/dt+ and dP/dt-) during I/R and infarction size. In addition, cardiac tissue was analyzed for oxidative stress by lipid peroxidation and protein carbonyl levels along with activity of catalase and superoxide dismutase (SOD). LVDP was higher in hearts from M and E groups as well as decreased infarction sizes than others. At the end of reperfusion, dP/dt+ was increased in E and M and dP/dt- was higher in M. LVSP was higher in M and E compared with C. Protein carbonyl and thiobarbituric acid reactive substances levels were higher in M while SOD activity was increased in E. No differences were observed in other activities. The results suggest that short-term consumption of IP/mate has protective effects on heart I/R injury similar to exercise, but the combination of these interventions appears to contradict the beneficial adaptations from exercise.

Abstract
Cardiovascular diseases are the main cause of mortality and morbidity in the world. Hypertension, ischemia/reperfusion, diabetes and anti-cancer drugs contribute to heart failure through oxidative and nitrosative stresses which cause cardiomyocytes nuclear and mitochondrial DNA damage, denaturation of intracellular proteins, lipid peroxidation and inflammation. Oxidative or nitrosative stress-mediated injury lead to cardiomyocytes apoptosis or necrosis. The reactive oxygen (ROS) and nitrogen species (RNS) concentration is dependent on their production and on the expression and activity of anti-oxidant enzymes. Polyphenols are a large group of natural compounds ubiquitously expressed in plants, and epidemiological studies have shown associations between a diet rich in polyphenols and the prevention of various ROS-mediated human diseases. Polyphenols reduce cardiomyocytes damage, necrosis, apoptosis, infarct size and improve cardiac function by decreasing oxidative stress-induced production of ROS or RNS. These effects are achieved by the ability of polyphenols to modulate the expression and activity of anti-oxidant enzymes and several signaling pathways involved in cells survival. This report reviews current knowledge on the potential anti-oxidative effects of polyphenols to control the cardiotoxicity induced by ROS and RNS stress.

Abstract
Objective(s): Oxidative stress has been established as a key cause of alcohol-induced hepatotoxicity. Licochalcone B, an extract of licorice root, has shown antioxidative properties. This study was to investigate the effects and mechanisms of licochalcone B in ethanol-induced hepatic injury in an in vitro study. Materials and Methods: An in vitro model of Ethanol-induced cytotoxicity in BRL cells was used in this study. Cell injury was assessed using WST-1 assay and lactate dehydrogenase, alanine transaminase, and aspartate aminotransferase release assay. Cell apoptosis were quantified by flow cytometric analysis. The intracellular oxidative level was evaluated by reactive oxidative species, malondialdehyde and glutathione detection. Furthermore, the expression level of Erk, p-Erk, Nrf-2 were assessed using Western blot. Results: Treatment with ethanol induced marked cell injury and cell apoptosis in BRL cells. Licochalcone B significantly attenuated ethanol-induced cell injury, and inhibited cell apoptosis. Furthermore, licochalcone B significantly inhibited ethanol-induced intracellular oxidative level, upregulated the expression of p-Erk, and promoted nuclear localization of Nrf2. Additionally, this hepatoprotective role was significantly abolished by inhibition of Erk signaling. However, no apparent effects of Erk inhibition were observed on ethanol-induced hepatotoxicity. Conclusion: This study demonstrates that licochalcone B protects hepatocyte from alcohol-induced cell injury, and this hepatoprotective role might be attributable to apoptosis reduction, inhibition of oxidative stress, and upregulation of Erk–Nrf2. Therefore, licochalcone B might possess potential as a novel therapeutic drug candidate for alcohol-related liver disorders.

Abstract
OBJECTIVES The objective of this study was to investigate the hepatoprotective effect of licochalcone B (LCB) in a mice model of carbon tetrachloride (CCl4)-induced liver toxicity. MATERIALS AND METHODS Hepatotoxicity was induced in mice by a single subcutaneous injection (SC) of CCl4. The LCB was administered orally once a day for seven days (PO) as pretreatment at three doses of 1, 5, and 25 mg/kg/day. The levels of superoxide dismutase (SOD), malondialdehyde (MDA), glutathione (GSH), glutathione disulfide (GSSG), C-reactive protein (CRP), tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), alanine aminotransferase (ALT) and aspartate aminotransferase (AST) were analyzed by ELISA. The protein expression degrees of p38 mitogen activated protein kinases (p38) and nuclear factor-k-gene binding (NF-κB) were assayed by western blotting. RESULTS CCl4-induced hepatotoxicity was manifested by an increase in the levels of ALT, AST, MDA, IL-6, CRP, and TNF-ɑ, and a decrease in the SOD level and GSH/GSSG ratio in the serum. The histopathological examination of the liver sections revealed necrosis and inflammatory reactions. Pretreatment with LCB decreased the levels of ALT, AST, MDA, GSSG, IL-6, CRP, TNF-ɑ, and the protein expression of p38 and NF-κB, increased the level of SOD and GSH, and normalized the hepatic histo-architecture. CONCLUSION LCB protected the liver from CCl4-induced injury. Protection may be due to inhibition of p38 and NFκB signaling, which subsequently reduced inflammation in the liver.

Abstract
BACKGROUND Atorvastatin and remote ischemic preconditioning (RIPC) have beneficial cardiovascular protective effects. The aim of the study was to investigate possible effect of this drug alone and in combination with RIPC on the biochemical changes induced by ischemic/reperfusion injury (I/R) in a combined study with a clinical and experimental animal arm. METHODS Thirty consecutive patients undergoing elective percutaneous coronary intervention (PCI) were divided into three groups (10 each): group I (control group without any preconditioning), group II (patients who were maintained on atorvastatin (80mg/day) for one month before PCI), and group III (similar to group II but PCI was preceded by RIPC). On the other hand, sixty adult male New Zealand white rabbits were divided into 6 groups (10 each): group I (control), group II (sham), group III (I/R as 30min ischemia followed by 120min reperfusion), group IV (regular atorvastatin 10mg/kg for 40days orally followed by I/R), group V (I/R preceded by RIPC) and group VI (similar to group IV but I/R was preceded by RIPC). Tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), nitric oxide (NO), troponin I (cTnI), creatine kinase MB (CK-MB) and C-reactive protein (CRP) were measured in blood for all study groups. RESULTS Clinical and experimental parts showed that groups with RIPC combined with atorvastatin pre-treatment showed a synergistic protective effect against I/R injury as evidenced by significant reduction (P<0.001) in the levels of TNF-α, cTnI (in patients) and IL-6, CK-MB and CRP (in rabbits) while the level of NO was significantly (P<0.001) increased compared with other groups. CONCLUSIONS Pretreatment with atorvastatin combined with RIPC can exert a synergistic cardioprotective effects by reducing the possible biochemical changes related to ischemic reperfusion injury.

Abstract
Background This study evaluated the protective effect of Echinatin against myocardial ischemia/reperfusion (I/R) injury in rats. Methods The effect of Echinatin on cardiac function in rats subjected to I/R was demonstrated through improved Langendorff retrograde perfusion technology. Adult Sprague–Dawley rats were randomly divided into five groups, and myocardial infarct size was macroscopically estimated through 2,3,5-triphenyltetrazolium chloride staining. The coronary effluent was analyzed for the release of lactate dehydrogenase (LDH) and creatine kinase (CK) to assess the degree of cardiac injury. The concentrations of malondialdehyde (MDA), interleukin-6 (IL-6), and tumor necrosis factor-α (TNF-α) were determined along with superoxide dismutase (SOD) activity using ELISA. Finally, cardiomyocyte apoptosis analysis was conducted with POD, an in situ cell death detection kit. Results Echinatin (0.5 and 2.5 μg/mL) pretreatment enhanced the maximum up/down rate of the left ventricular pressure (±dp/dtmax), improved the heart rate, increased the left ventricular developed pressure (LVDP), enhanced the coronary flow, and reduced the CK and LDH levels in the coronary flow of the treated group compared with the I/R group. Echinatin limited the contents of CK and LDH, improved the LVDP, reduced the contents of MDA, IL-6, and TNF-α, and increased the SOD activity. The infarct size and cell apoptosis in the hearts of the rats in the Echinatin-treated group were smaller and lower, respectively, than those in the hearts of the rats in the I/R control group. Conclusion Echinatin exerts a protective effect against I/R-induced myocardial injury on hearts. This effect may be attributed to the antioxidant and anti-inflammatory activities of this compound.

Paeonol and danshensu combination attenuates apoptosis in myocardial infarcted rats by inhibiting oxidative stress: Roles of Nrf2/HO-1 and PI3K/Akt pathway. Sci Rep 2016; 6:23693.

Abstract
Paeonol and danshensu is the representative active ingredient of traditional Chinese medicinal herbs Cortex Moutan and Radix Salviae Milthiorrhizae, respectively. Paeonol and danshensu combination (PDSS) has putative cardioprotective effects in treating ischemic heart disease (IHD). However, the evidence for the protective effect is scarce and the pharmacological mechanisms of the combination remain unclear. The present study was designed to investigate the protective effect of PDSS on isoproterenol (ISO)-induced myocardial infarction in rats and to elucidate the potential mechanism. Assays of creatine kinase-MB, cardiac troponin I and T and histopathological analysis revealed PDSS significantly prevented myocardial injury induced by ISO. The ISO-induced profound elevation of oxidative stress was also suppressed by PDSS. TUNEL and caspase-3 activity assay showed that PDSS significantly inhibited apoptosis in myocardia. In exploring the underlying mechanisms of PDSS, we found PDSS enhanced the nuclear translocation of Nrf2 in myocardial injured rats. Furthermore, PDSS increased phosphorylated PI3K and Akt, which may in turn activate antioxidative and antiapoptotic signaling events in rat. These present findings demonstrated that PDSS exerts significant cardioprotective effects against ISO-induced myocardial infarction in rats. The protective effect is, at least partly, via activation of Nrf2/HO-1 signaling and involvement of the PI3K/Akt cell survival signaling pathway.

Abstract
Naringin (Nar) is a major and active flavanone glycoside derivative of several citrus species. The antioxidant properties of Nar have an important function in its cardioprotective effects in various models. However, the effects of Nar on Nrf2 activation and the expression of its downstream genes in myocardial cells are yet to be elucidated. This study was designed to investigate the protective effects of Nar against anoxia/reoxygenation (A/R)-induced injury in H9c2 cells and determine its effects on the activity of Nrf2 and the expression of phase II antioxidant enzymes. H9c2 cells were pretreated with Nar for 6 h before exposure to A/R. A/R treatment severely injured the H9c2 cells, which was accompanied by apoptosis. Nar also suppressed the A/R-induced mitochondrial membrane depolarization and caspase-3 activation. Nar pretreatment significantly reduced the apoptotic rate by enhancing the endogenous anti-oxidative activity of superoxide dismutase, glutathione peroxidase, and catalase, thereby inhibiting intracellular reactive oxygen species generation. Moreover, the presence of Nar alone in H9c2 cells increased the nuclear translocation of Nrf2 in a dose- and time-dependent manner, as well as consistently increased the protein levels of heme oxygenase (HO-1) and glutamate cysteine ligase (GCLC). Nar increased the phosphorylation of ERK1/2, PKCδ, and AKT. However, the Nar-mediated Nrf2 activation and cardioprotection were abolished through the genetic silencing of Nrf2 by siRNA and partially inhibited by specific inhibitors of ERK1/2, PKCδ, and AKT. Therefore, Nar provided cardioprotection by inducing the phosphorylation of ERK1/2, PKCδ, and AKT, which subsequently activated Nrf2 and its downstream genes.

Abstract
Background and Purpose Previous studies have demonstrated that angiotensin-converting enzyme (ACE) is involved in brain ischemic injury. In the present study, we investigated whether Scutellarin (Scu) exerts neuroprotective effects by down-regulating the Expression of Angiotensin-Converting Enzyme and AT1 receptor in a rat model of permanent focal cerebral ischemia. Methods Adult Sprague–Dawley rats were administrated with different dosages of Scu by oral gavage for 7 days and underwent permanent middle cerebral artery occlusion (pMCAO). Blood pressure was measured 7 days after Scu administration and 24 h after pMCAO surgery by using a noninvasive tail cuff method. Cerebral blood flow (CBF) was determined by Laser Doppler perfusion monitor and the neuronal dysfunction was evaluated by analysis of neurological deficits before being sacrificed at 24 h after pMCAO. Histopathological change, cell apoptosis and infarct area were respectively determined by hematoxylin–eosin staining, terminal deoxynucleotidyl transfer-mediated dUTP nick end labeling (TUNEL) analysis and 2,3,5-triphenyltetrazolium chloride staining. Tissue angiotensin II (Ang II) and ACE activity were detected by enzyme-linked immunosorbent assays. The expression levels of ACE, Ang II type 1 receptor (AT1R), tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), and interleukin-1β (IL-1β) were measured by Western blot and real-time PCR. ACE inhibitory activity of Scu in vitro was detected by the photometric determination. Results Scu treatment dose-dependently decreased neurological deficit score, infarct area, cell apoptosis and morphological changes induced by pMCAO, which were associated with reductions of ACE and AT1R expression and the levels of Ang II, TNF-α, IL-6, and IL-1β in ischemic brains. Scu has a potent ACE inhibiting activity. Conclusion Scu protects brain from acute ischemic injury probably through its inhibitory effect on the ACE/Ang II/AT1 axis, CBF preservation and proinflammation inhibition.

Abstract
This study aims to evaluate the cardioprotective effects of astragalin against myocardial ischemia/reperfusion (I/R) injury in isolated rat heart. The cardioprotective effects of astragalin on myocardial I/R injury were investigated on Langendorff apparatus. Adult male Sprague-Dawley rats were randomly divided into five groups. The results showed that astragalin pretreatment improved myocardial function. Compared with I/R group, lactate dehydrogenase (LDH) and creatine kinase (CK) activities in coronary flow decreased in astragalin pretreatment groups, whereas superoxide dismutase (SOD) activity and glutathione/glutathione disulfide (GSH/GSSG) ratio significantly increased. The levels of malondialdehyde (MDA), intracellular reactive oxygen species (ROS), tumor necrosis factor-α (TNF-α), and interleukin-6 (IL-6) decreased in astragalin-treated groups. The infarct size (IS) and apoptosis rate in hearts from astragalin-treated groups were lower than those in hearts from the I/R group. Western blot analysis also revealed that astragalin preconditioning significantly reduced Bax level, whereas Bcl-2 was increased in the myocardium. Therefore, astragalin exhibited cardioprotective effects via its antioxidative, antiapoptotic, and anti-inflammatory activities.

Abstract
The aim of the present study was to investigate the effects and mechanisms of calycosin‑7‑O‑β‑D‑glucoside (CG) on ischemia‑reperfusion (I/R) injury in vivo. Hemodynamic parameters, including ejection fraction (EF), fractional shortening (FS), left ventricular end‑systolic pressure (LVESP) and left ventricular end‑diastolic pressure (LVEDP) were monitored using an ultrasound system, and infarct size was measured using Evans blue/tetrazolium chloride double staining. The activities of serum creatine kinase (CK), lactate dehydrogenase (LDH) and superoxide dismutase (SOD), and the levels of malondialdehyde (MDA) were determined to assess the degree of myocardial injury and oxidative stress‑induced damage. The protein expression levels of cleaved‑caspase‑3, cleaved‑caspase‑9, phosphorylated (p)‑phosphatidylinositol 3‑kinase (PI3K) p85, PI3K p85, p‑Akt and Akt were determined using western blotting. The results demonstrated that pretreatment with high dose (H)‑CG markedly improved cardiac function, as evidenced by upregulated EF, FS and LVESP, and downregulated LVEDP. In addition, administration of CG resulted in significant decreases in infarct size in the I/R+low dose‑CG and I/R+H‑CG groups, compared with the I/R group. The activities of CK and LDH, and the levels of MDA in the I/R+H‑CG group were reduced, compared with those in the I/R group, whereas SOD activity was elevated. Treatment with CG inhibited the cleavage and activity of caspase‑3 and caspase‑9, and enhanced the phosphorylation of PI3K p85 and Akt. Notably, administration of the PI3K inhibitor, LY294002, markedly lowered the levels of p‑PI3K p85/p‑Akt, and eradicated the inhibitory effects of H‑CG on infarct size, myocardial injury and oxidative stress‑induced damage. Taken together, the results suggested that CG may alleviate I/R injury by activating the PI3K/Akt signaling pathway.

Adenosine 2B Receptor Activation Reduces Myocardial Reperfusion Injury by Promoting Anti-Inflammatory Macrophages Differentiation via PI3K/Akt Pathway. OXIDATIVE MEDICINE AND CELLULAR LONGEVITY 2015; 2015:585297.

Abstract
BACKGROUND Activation of the adenosine A2B receptor (A2BR) can reduce myocardial ischemia/reperfusion (IR) injury. However, the mechanism underlying the A2BR-mediated cardioprotection is less clear. The present study was designed to investigate the potential mechanisms of cardioprotection mediated by A2BR. METHODS AND RESULTS C57BL/6 mice underwent 40-minute ischemia and 60-minute reperfusion. ATL-801, a potent selective A2BR antagonist, could not block ischemic preconditioning induced protection. BAY 60-6583, a highly selective A2BR agonist, significantly reduced myocardial infarct size, and its protective effect could be blocked by either ATL-801 or wortmannin. BAY 60-6583 increased phosphorylated Akt (p-Akt) levels in the heart at 10 min of reperfusion, and this phosphorylation could also be blocked by ATL-801 or wortmannin. Furthermore, BAY 60-6583 significantly increased M2 macrophages and decreased M1 macrophage and neutrophils infiltration in reperfused hearts, which also could be blocked by wortmannin. Meanwhile, confocal imaging studies showed that the majority of Akt phosphorylation in the heart was colocalized to CD206+ cells in both control and BAY 60-6583 pretreated hearts. CONCLUSION Our results indicated that pretreatment with BAY 60-6583 protects the heart against myocardial IR injury by its anti-inflammatory effects, probably by modulating macrophages phenotype switching via a PI3K/Akt pathway.

Dexmedetomidine Analgesia Effects in Patients Undergoing Dental Implant Surgery and Its Impact on Postoperative Inflammatory and Oxidative Stress. OXIDATIVE MEDICINE AND CELLULAR LONGEVITY 2015; 2015:186736. [PMID: 26171113 PMCID: PMC4485522 DOI: 10.1155/2015/186736] [Citation(s) in RCA: 28] [Impact Index Per Article: 3.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 09/15/2014] [Accepted: 11/18/2014] [Indexed: 12/31/2022]
Abstract
The aim of the study was to determine whether or not dexmedetomidine- (DEX-) based intravenous infusion in dental implantation can provide better sedation and postoperative analgesia via suppressing postoperative inflammation and oxidative stress. Sixty patients were randomly assigned to receive either DEX (group D) or midazolam (group M). Recorded variables were vital sign (SBP/HR/RPP/SpO2/RR), visual analogue scale (VAS) pain scores, and observer's assessment of alertness/sedation scale (OAAS) scores. The plasma levels of interleukin-6 (IL-6), tumor necrosis factor alpha (TNF-α), antioxidant superoxide dismutase (SOD), and the lipid peroxidation product malondialdehyde (MDA) were detected at baseline and after 2, 4, and 24 h of drug administration. The VAS pain scores and OAAS scores were significantly lower for patients in group D compared to group M. The plasma levels of TNF-α, IL-6, and MDA were significantly lower in group D patients than those in group M at 2 h and 4 h. In group M, SOD levels decreased as compared to group D at 2 h and 4 h. The plasma levels of TNF-α, IL-6, and MDA were positively correlated with VAS pain scores while SOD negatively correlated with VAS pain scores. Therefore, DEX appears to provide better sedation during office-based artificial tooth implantation. DEX offers better postoperative analgesia via anti-inflammatory and antioxidation pathway.

Cardioprotective Effect of Licochalcone D against Myocardial Ischemia/Reperfusion Injury in Langendorff-Perfused Rat Hearts. PLoS One 2015; 10:e0128375. [PMID: 26058040 PMCID: PMC4461317 DOI: 10.1371/journal.pone.0128375] [Citation(s) in RCA: 28] [Impact Index Per Article: 3.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/27/2014] [Accepted: 04/25/2015] [Indexed: 11/25/2022] Open
Abstract
Flavonoids are important components of ‘functional foods’, with beneficial effects on cardiovascular function. The present study was designed to investigate whether licochalcone D (LD) could be a cardioprotective agent in ischemia/reperfusion (I/R) injury and to shed light on its possible mechanism. Compared with the I/R group, LD treatment enhanced myocardial function (increased LVDP, dp/dtmax, dp/dtmin, HR and CR) and suppressed cardiac injury (decreased LDH, CK and myocardial infarct size). Moreover, LD treatment reversed the I/R-induced cleavage of caspase-3 and PARP, resulting in a significant decrease in proinflammatory factors and an increase in antioxidant capacity in I/R myocardial tissue. The mechanisms underlying the antiapoptosis, antiinflammation and antioxidant effects were related to the activation of the AKT pathway and to the blockage of the NF-κB/p65 and p38 MAPK pathways in the I/R-injured heart. Additionally, LD treatment markedly activated endothelial nitric oxide synthase (eNOS) and reduced nitric oxide (NO) production. The findings indicated that LD had real cardioprotective potential and provided support for the use of LD in myocardial I/R injury.

Role of licochalcone C in cardioprotection against ischemia/reperfusion injury of isolated rat heart via antioxidant, anti-inflammatory, and anti-apoptotic activities. Life Sci 2015; 132:27-33. [PMID: 25921769 DOI: 10.1016/j.lfs.2015.04.008] [Citation(s) in RCA: 20] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/27/2014] [Revised: 03/30/2015] [Accepted: 04/06/2015] [Indexed: 12/30/2022]
Abstract
AIMS This study aimed to evaluate the protective effect of licochalcone C against myocardial ischemia/reperfusion injury in rats. MAIN METHODS Left ventricular developed pressure (LVDP) and its maximum up/down rate (±dp/dtmax) were recorded as myocardial function. Levels of creatine kinase (CK), lactate dehydrogenase (LDH), malondialdehyde (MDA), superoxide dismutase (SOD), glutathione/glutathione disulfide (GSH/GSSG) ratio, and tumor necrosis factor-alpha (TNF-α) were determined by using enzyme-linked immunosorbent assay. Cell morphology was observed and mitochondrial damage was assessed by HE coloration and transmission electron microscopy, respectively. Cardiomyocyte apoptosis was determined by using terminal deoxynucleotidyl transferased UTP nick-end labeling (TUNEL). KEY FINDINGS Pretreatment with licochalcone C significantly improved the recovery of LVDP and ±dp/dtmax, and increased the levels of SOD and GSH/GSSG ratio. However, pretreatment with licochalcone C not only decreased the TUNEL-positive cell ratio and morphological changes, but also weaken the mitochondrial injury and the levels of CK, LDH, MDA, and TNF-α. SIGNIFICANCE These results suggested an important function of licochalcone C extracted from traditional Chinese medicine in the cardioprotection via antioxidant, anti-inflammatory, and anti-apoptotic activities.
