Abstract
Plants' bioactives are well-known safe drugs for vital diseases. Flavones and Flavonoid-rich dietary supplements are known to exhibit neuroprotective potential. In this study, we isolated a flavone 2-(3,4-dimethoxyphenyl)-3,7-dihydroxy-4H-chromen-4-one from Notholirion thomsonianum and it was evaluated against various targets of the oxidative stress-related neurological disorders. The compound showed excellent acetyl and butyrylcholinesterase inhibitions in its profile, giving IC50 values of 1.37 and 0.95 μM, respectively. Similarly, in in-vitro MAO-B assay, our flavone exhibited an IC50 value of 0.14 μM in comparison to the standard safinamide (IC50 0.025 μM). In in-vitro anti-inflammatory assay, our isolated compound exhibited IC50 values of 7.09, 0.38 and 0.84 μM against COX-1, COX-2 and 5-LOX, respectively. The COX-2 selectivity (SI) of the compound was 18.70. The compound was found safe in animals and was very effective in carrageenan-induced inflammation. Due to the polar groups in the structure, a very excellent antioxidant profile was observed in both in-vitro and in-vivo models. The compound was docked into the target proteins of the respective activities and the binding energies confirmed the potency of our compound. Furthermore, absorption, distribution, metabolism, excretion, and toxicity (ADMET) results showed that the isolated flavone has a good GIT absorption ability and comes with no hepatic and cardiotoxicity. In addition, the skin sensitization test, in-vitro human cell line activation test (h-CLAT) and KeratinoSens have revealed that isolated flavone is not skin sensitive with a confidence score of 59.6% and 91.6%. Herein, we have isolated a natural flavone with an effective profile against Alzheimer's, inflammation and oxidative stress. The exploration of this natural flavone will provide a baseline for future research in the field of drug development.

[PMID: 32917166 PMCID: PMC7488457 DOI: 10.1186/s12882-020-02053-8] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/09/2020] [Accepted: 09/02/2020] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Platelet activation is an important side effect of dialysis, resulted in a subsequent release of arachidonic acid (AA) from activated platelets. AA is involved in many pathologic conditions, such as inflammation, asthma, cancer, diabetes, hypertension, and the pathogenesis of kidney disease. The aim of this study was to define whether the dialysis type affects the concentration of AA derivatives in patients with chronic kidney disease. METHODS 117 patients were qualified to the study group. Based on the type of renal replacement therapy, patients were divided into the following groups: hemodialysis (HD A - before/HD B - after hemodialysis), peritoneal dialysis (PD), kidney transplant patients (TE - before/TE A - after transplantation) and conservative treatment (CT) (30; 30; 27; 30 patients, respectively). The control group consisted of 30 healthy volunteers (NK). The ELISA methods were used to measure the concentrations of TXB2, 5-HETE, 12-HETE, and 15-HETE in the blood serum. RESULTS Renal replacement therapy significantly influences the concentration of TXB2 (mean ± SD [ng/mL]: HD A- 34.6 ± 9; HD B- 28.3 ± 15.2; PD- 28.3 ± 15.2; CT- 34.2 ± 8.0; TE- 36.7 ± 42.9; TE A- 27.9 ± 8.8; NK- 19.6 ± 15; p = 0.010), 5-HETE (mean ± SD [ng/mL]: HD A- 284.2 ± 428.4; HD B- 304.8 ± 516.2; PD - 530.0 ± 553.3; CT- 318.7 ± 366.0; TE- 525.6 ± 358.0; TE A - 409.8 ± 377.1; NK 838.1 ± 497.8; p < 0.001) and 15-HETE (HD A-18.1 ± 8.7; HD B- 42.2 ± 14; PD - 36.3 ± 13.8; CT- 33.7 ± 14.0; TE- 19.5 ± 10.2; TE A - 34.4 ± 16.3; NK 22.2 ± 17.8; p < 0,001). There was a significant relationship between the type of renal replacement therapy and the duration of dialysis, and the concentration of TXB2, 12-HETE acid, and 15-HETE. CONCLUSIONS The type of renal replacement therapy significantly affects the concentration of AA derivatives. Peritoneal dialysis is the best method of dialysis, taking into account the concentration of arachidonic acid derivatives.

Abstract
Recently, air pollution has been identified as a significant modifiable risk factor to the increasing stroke burden. Diesel exhaust particles, characterized by high polycyclic aromatic hydrocarbons content, constitute an important component of outdoor air pollution and is known to cause oxidative stress, and could therefore contribute to and exacerbate the effects of ROS in post-ischemic injury. hCMEC/D3 cells have been submitted to 48h treatment with diesel exhaust particles (25μg/ml and 50μg/ml, DEP50) or alternatively to 3h of oxygen and glucose deprivation, followed by 1h of oxygen and glucose restoration. The combined treatment consisted in 48h of diesel exhaust particles (25μg/ml and 50μg/ml, DEP50) followed by 3h of oxygen and glucose deprivation and 1h of restoration. A panel of markers related to oxidative stress and inflammatory responses, such as transcription factors (Nrf2 and HIF-1α), anti-oxidant proteins (HO-1, SOD-1, Hsp70) and proteins potentially inducing further oxidative-stress or inflammation (Cyp1b1, iNOS, COX-2, TNF-α, IL-1α, IL-1β, IL-8, VEGF), have been examined. Data obtained showed that diesel exhaust particles and oxygen and glucose deprivation treatments alone elicited the antioxidants response, each by means of a different transcription factor, while the combined treatment led to a dysregulation of the antioxidant response during ischemic injury reperfusion.

Abstract
Prevalence of metabolic syndrome and progression of nephropathy depend on sex. We examined a protective effect of estradiol against nephropathy in metabolic syndrome through the modulation of the arachidonic acid metabolism by activating the 5-lipoxygenase and cytochrome p450 4A pathways. 28 female Wistar rats were divided into four groups of seven animals each: control, intact metabolic syndrome, ovariectomized metabolic syndrome, and metabolic syndrome ovariectomized plus estradiol. Blood pressure, body weight, body fat, triglycerides, insulin, HOMA-index, albuminuria, and TNF-α were increased in ovariectomized metabolic syndrome rats (p < 0.001). The perfusion pressure in isolated kidneys of ovariectomized metabolic syndrome rats in presence of 4 μg of arachidonic acid was increased. The inhibitors of the arachidonic acid metabolism Baicalein, Miconazole, and Indomethacin in these rats decreased the perfusion pressure by 57.62%, 99.83%, and 108.5%, respectively and they decreased creatinine clearance and the arachidonic acid percentage. Phospholipase A2 expression in the kidney of ovariectomized metabolic syndrome rats was not modified. 5-lipoxygenase was increased in metabolic syndrome ovariectomized rats while cytochrome p450 4A was decreased. In conclusion, the loss of estradiol increases renal damage while the treatment with estradiol benefits renal function by modulating arachidonic acid metabolism through the 5-lipoxygenase and cytochrome p450 4A pathways.

Abstract
BACKGROUND Acute kidney injury (AKI) is one of the major health problems in developed as well as developing countries. The literature regarding the role of N-methyl-D-aspartate receptors (NMDAR) and the impact of the modulation of its allosteric sites on renal function is inadequate. The present study investigated the effect of modulating allosteric sites of NMDAR in ischemia-reperfusion-induced AKI. MATERIALS AND METHODS We subjected rats to bilateral renal ischemia for 40 min followed by reperfusion for 24 h to induce AKI. We measured blood urea nitrogen, serum creatinine, uric acid, and lactate dehydrogenase to assess kidney injury. We assayed the thiobarbituric acid-reactive substances, reduced glutathione level, and myeloperoxidase and catalase activity to assess oxidative stress in renal tissue, and used hematoxylin-eosin staining to observe histopathologic changes. RESULTS Ischemia-reperfusion induced AKI, as demonstrated by an increase in serum parameters, oxidative stress and histopathologic changes in renal tissue. The NMDA agonist glutamic acid and polyamine binding site agonist spermidine significantly aggravated oxidative stress and ischemia-reperfusion-induced AKI. Various NMDA receptor antagonists, including glycine binding site inhibitor kynurenic acid, polyamine binding site inhibitor ketamine, and channel blocking agent magnesium sulfate, attenuated ischemia-reperfusion-induced AKI and significantly reduced oxidative stress, which suggests a role for NMDA receptors and the importance of regulating its allosteric sites in AKI. CONCLUSIONS Acute kidney injury is associated with the activation of NMDA receptors, as well as significant oxidative stress. The antagonism of various allosteric sites of NMDA receptors affords significant benefit against ischemia-reperfusion-induced AKI.

Abstract
We aimed to determine whether rotenone treatment prevents induced ischemia/reperfusion (I/R) damage in rat bladders by detecting inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) levels by real-time PCR (RT-PCR). A total of 18 Sprague-Dawley albino rats were used in this experiment. The experimental groups each consisted of 6 rats and were treated as follows: group I, control; group II, I/R; group III, rotenone + I/R. In the control group, the rat bladders were removed by lower abdominal incision without any procedure. In the I/R group, 1 h prior to the ischemia 1 cc physiological serum was administered and the abdominal aortas were clamped for 1 h to achieve bladder ischemia. Following the ischemia, reperfusion was induced for 1 h and the bladders were removed. In the rotenone + I/R group, the rats were treated with 25 mg/kg rotenone intraperitoneally. The iNOS and COX-2 mRNA levels in each group were detected using RT-PCR. In the I/R group, the COX-2 levels in the bladder tissue were higher compared with the control group (P<0.05). The COX-2 levels in the rotenone-treated group were statistically lower compared with the I/R group (P<0.01). Vascularization and edema were markedly increased in the I/R group. Following rotenone treatment these were abrogated inversely to inflammation. Although iNOS levels were slightly higher in the I/R group compared with the control group, iNOS levels did not decrease and no significant difference was observed between the groups with regard to rotenone treatment (P>0.05). We suggest that rotenone may be used clinically to treat I/R damage due to its diminishing effect on COX-2 levels.

Abstract
Ischemia/reperfusion injury is a major problem in renal transplantation. Several evidences represent lithium preconditioning effect against ischemia/reperfusion injury in various tissues. In this study our aim was to investigate the protective effect of chronic lithium administration on renal ischemia/reperfusion injury in rats. Ischemia/reperfusion injury was induced by clamping left renal pedicle for 60 min, 2 weeks after right nephrectomy. Lithium-treated animals received lithium-chloride in drinking water for 30days. In order to investigate the role of nitric oxide (NO) and cyclooxygenase (COX) pathways in renoprotective effect of lithium, N(ω)-nitro-L-arginine methyl ester hydrochloride (L-NAME, NO synthase inhibitor) and indomethacin (COX inhibitor) were used, respectively. Serum creatinine, blood urea nitrogen and renal histology were assessed 24h after inducing ischemia/reperfusion injury. Dimercaptosuccinic acid scan was also performed 48 h following operation. Chronic lithium treatment in ischemia/reperfusion injury groups significantly decreased creatinine (1.09±0.16 mg/dl), blood urea nitrogen (59.0±13.38 mg/dl), histological damage (7.83%±4.02%) and improved cortical function compared with non-lithium treated animals (4.45±0.44, 176.66±12.24 mg/dl and 83.5%±3.5%, respectively) (P<0.001). Either L-NAME or indomethacin administration partially reversed the protective effect of lithium, while simultaneous blockade of NO and COX pathways completely abolished lithium renoprotective effect. Our results indicate that lithium ameliorates renal ischemia/reperfusion injury through NO and/or COX pathways. We propose that lithium pre-treatment as a simple and practical intervention to boost the renal viability and function after ischemia/reperfusion injury may be promising in the setting of transplantation.

Abstract
BACKGROUND Active metabolites of arachidonic acid (AA), eicosanoids, strongly influence renal homeostasis. The aims of this study were to measure perioperative variations in lipoxygenase (LOX)-derived 5-, 12- and 15-hydroxyeicosatetraenoic (HETE) acids levels, and to examine whether (i) dynamics of these eicosanoid generation changes during the first 5 min of renal allograft reperfusion, (ii) examined HETE acids may influence perioperative 20-HETE generation, and (iii) LOX HETE may serve as perioperative markers of early post-transplant allograft function. METHODS Sixty-nine kidney recipients were divided into early, slow and delayed graft function (EGF, SGF and DGF, respectively) groups. Blood was taken directly before, and in the consecutive minutes of graft reperfusion. HETE concentrations were measured using liquid chromatography. Creatinine levels were measured during the perioperative period, as well as during follow-up visits (first post-transplant year). RESULTS Our results demonstrated significant differences in the concentrations and dynamics of HETE changes between the examined groups. Moreover, observed changes in HETE concentrations were strongly associated with post-transplant graft function and perioperative 20-HETE synthesis. Application of cut-off limits for newly introduced markers, that is 71.72 ng/mL for 5-HETE(5), 12.3 ng/mL for 12-HETE△(5-0) and -6.1 ng/mL for 15-HETE△(5-0), resulted in 72.5-81.5% sensitivity and 50-54% specificity for SGF/DGF prediction. Moreover, mixed model analysis revealed that recipients classified according to results of 5-HETE(5) and 15-HETE△(5-0) significantly differ in 1-year post-transplant allograft function (P = 0.03 and P < 0.05, respectively), however, not in the frequency of acute rejections' episodes (P = 0.91 and P = 0.31, respectively). CONCLUSION We hereby report that human kidney transplantations are accompanied by significant changes in LOX AA metabolism, which strongly influences and predicts early (1 year) post-transplant graft function.

Abstract
The pathogenesis of ischemia-reperfusion (I/R) injury is known to involve cytokines and particularly surface adhesion molecules, the expression of which initiates the attachment of inflammatory cells. Renal I/R injury, a clinically important problem, is an invariable consequence of renal transplantation. The problem begins at the onset of acute tubular necrosis (ATN), when the transplantation includes a long ischemic interval or by use of a cardiac arrest donor's kidney. The cysteinyl leukotriene-1 (CysLT(1)), a potent lipid mediator in allergic disease, acts through the CysLT(1)R receptor. We researched the expression of CysLT(1)R in rat renal I/R injury as well as correlations with the degree of ATN. The right kidney was harvested and the left renal artery and vein were clamped at laparotomy. The kidney was reperfused after 90 minutes of ischemia; rats were sacrificed at 0, 3, 5, 12, and 24 hours after reperfusion. CysLT(1)R expression was analyzed by immunohistochemistry. CysLT(1)R expression was observed only in endothelial cells of a normal kidney. CysLT(1)R expression was most intense on endothelial cells at 3 hours after reperfusion, and CysLT(1)R expression on endothelial cells gradually became weaker. Twelve hours after reperfusion, ATN extended throughout the ischemic kidney. Renal I/R injury gradually progressed at time after reperfusion. Several hours after the maximal CysLT(1)R expression, we observed the maximum renal I/R injury.

Abstract
OBJECTIVE To determine the effect of meloxicam and flunixin meglumine on recovery of ischemia-injured equine jejunum. ANIMALS 18 horses. PROCEDURES Horses received butorphanol tartrate; were treated IV with saline (0.9% NaCl) solution (SS; 12 mL; n = 6), flunixin meglumine (1.1 mg/kg; 6), or meloxicam (0.6 mg/kg; 6) 1 hour before ischemia was induced for 2 hours in a portion of jejunum; and were allowed to recover for 18 hours. Flunixin and SS treatments were repeated after 12 hours; all 3 treatments were administered immediately prior to euthanasia. Selected clinical variables, postoperative pain scores, and meloxicam pharmacokinetic data were evaluated. After euthanasia, assessment of epithelial barrier function, histologic evaluation, and western blot analysis of ischemia-injured and control jejunal mucosa samples from the 3 groups were performed. RESULTS Meloxicam- or flunixin-treated horses had improved postoperative pain scores and clinical variables, compared with SS-treated horses. Recovery of transepithelial barrier function in ischemia-injured jejunum was inhibited by flunixin but permitted similarly by meloxicam and SS treatments. Eighteen hours after cessation of ischemia, numbers of neutrophils in ischemia-injured tissue were higher in horses treated with meloxicam or flunixin than SS. Plasma meloxicam concentrations were similar to those reported previously, but clearance was slower. Changes in expression of proteins associated with inflammatory responses to ischemic injury and with different drug treatments occurred, suggesting cyclooxygenase-independent effects. CONCLUSIONS AND CLINICAL RELEVANCE Although further assessment is needed, these data have suggested that IV administration of meloxicam may be a useful alternative to flunixin meglumine for postoperative treatment of horses with colic.

Abstract
Renal ischemia-reperfusion (I/R) injury during renal transplantation is a significant cause of renal dysfunction. The pathological role of free radicals in this process is a major concern. We investigated the effect of a free radical scavenger, edaravone (MCI-186), in renal I/R injury. Male Lewis rats (270 to 320 g) were used for the model. The right kidney was harvested and left renal artery and vein were clamped as laparotomy. The kidney was reperfused after 90 minutes of ischemia. Edaravone (10 mg/kg) was delivered intravenously before ischemia and after reperfusion to prevent the neutrophil activation. In the nontreatment I/R group, no rat survived beyond 4 days. However, in the edaravone I/R treatment group, one among five rats survived more than 7 days. These results suggested that treatment with edaravone ameliorated renal I/R injury, and that the agent has the potential to ameliorate preservation injury in renal transplantation.

Abstract
BACKGROUND Cyclooxygenase (COX) is an intracellular enzyme that converts arachidonic acid to prostaglandin endoperoxide (PGG(2)). There are two isoforms of COX, namely constitutive COX-1 and inducible COX-2. It has been reported that COX-2 plays an important role in ischemia-reperfusion injury and that COX-2 mRNA and protein expression were up-regulated during cardiac allograft rejection. FK3311 is a suppressor of COX-2 activation. The purpose of this study was to evaluate the effectiveness of inhibiting COX-2 with FK3311 for the minimization of ischemia-reperfusion injury and for the improvement of donor heart function following transplantation in a canine model. MATERIALS AND METHODS Adult mongrel dogs were used. After the measurement of hemodynamic parameters [cardiac output (CO), left ventricular pressure (LVP), and the maximum rates of increase and decrease in LVP (+/-LVdp/dt)], coronary vascular beds were washed out with a hypothermic (4 degrees C) University of Wisconsin (UW) solution following cardiac arrest in response to cold (4 degrees C) glucose-insulin-potassium solution. The heart was then excised and preserved in hypothermic (4 degrees C) UW solution for 12 h. FK3311 (3 mg/kg) was administered intravenously to five dogs prior to reperfusion, while vehicle was administered intravenously to a control group (n = 5). After 3 h of orthotopic transplantation using cardiopulmonary bypass, the hemodynamic parameters were compared with preoperative values of the donor animals under the condition of 10 mm Hg right atrial pressure and 5 mug/kg/min dopamine support. RESULTS The recovery rates of CO and +/-LVdP/dt were significantly (P < 0.05) higher in the FK-treated dogs than in the controls (CO: 93 +/- 6 versus 66% +/- 4%; +LVdp/dt: 125 +/- 8 versus 77 +/- 10%; and -LVdp/dt: 81 +/- 7 versus 52 +/- 6%; for FK-treated versus control dogs, respectively). The recovery rate of LVP was higher in the FK-treated dogs than in the controls (90 +/- 5 versus 72 +/- 5%), but this difference was not statistically significant. Immunohistochemical staining revealed that COX-2 expression was reduced significantly in the myocardium of FK-treated dogs compared with controls. CONCLUSION Hemodynamic parameters following transplantation were improved significantly in dogs treated with FK3311. Therefore, the inhibition of COX-2 improves transplanted cardiac function following long-term preservation.

Abstract
AIM Polyenylphosphatidycholine has been demonstrated to have antioxidant, cytoprotective and anti-inflammatory effects. Whether polyenylphosphatidycholine pretreatment affects ischemia/reperfusion-induced renal damage in vivo is not known and was investigated here in rats. METHODS Forty female Sprague-Dawley rats were divided into three groups. Group 1 (n = 10) was given saline (control, sham operated). Group 2 (n = 15) were given saline, and Group 3 (n = 15) were given polyenylphosphatidycholine (100 mg/day for 10 days prior to experiment). Groups 2 and 3 were subjected to bilateral renal ischemia (60 min) followed by reperfusion (6 h). After the reperfusion period, the rats were sacrificed and kidney tissue superoxide dismutase, glutathione, total nitrite and nitrate, malondialdehyde and myeloperoxidase levels, plasma aspartate aminotransferase, blood urea nitrogen and creatinine concentrations, and nuclear factor kappa beta expression were determined. RESULTS Serum levels of aspartate aminotransferase, blood urea nitrogen and creatinine were significantly decreased (P < 0.05) in the treatment group compared to those in the ischemic group. There were significant differences between treatment and ischemic groups regarding the tissue superoxide dismutase, glutathione, total nitrite and nitrate, malondialdehyde, and myeloperoxidase levels (P < 0.05). In addition, polyenylphosphatidycholine pretreatment reduced nuclear factor kappa beta expression in ischemic kidney tissue. Kidneys obtained from rats pretreated with polyenylphosphatidycholine demonstrated marked reduction of the histological features of renal injury compared to kidneys obtained from Group 2 rats, including a little vacuolization, pyknosis and necrosis. CONCLUSIONS Polyenylphosphatidycholine pretreatment provided significant protection against ischemia/reperfusion injury to the kidney. This treatment could be therapeutic in kidney transplantation and other conditions associated with ischemia/reperfusion injury to the kidney.

Abstract
Renal ischaemia-reperfusion (I/R) injury is a clinically significant problem and an invariable consequence of renal transplantation. The problem begins at the onset of acute tubular necrosis (ATN), when the transplantation takes a long ischaemic interval by using the cardiac arrest donor's kidney. In addition, the longer the ischaemic interval, the higher the incidence rate of ATN. It is clinically important that renal I/R injury is reduced. The antisense oligodeoxynucleotide (AS-ODN), developed as a therapy for intractable diseases at the gene level, has recently been established as an important method in examining specific gene functions. The authors have previously demonstrated that AS-ODN/tissue factor (TF) prevents renal I/R injury. This review discusses the efficacy of AS-ODN/TF and AS-ODN/intercellular adhesion molecule-1 as existing targets, and the potential of AS-ODN/nuclear factor-kappaB, AS-ODN/cyclooxygenase and AS-ODN/5-lipoxygenase as prospective targets.
