Plants with Therapeutic Potential for Ischemic Acute Kidney Injury: A Systematic Review. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2022; 2022:6807700. [PMID: 35656467 PMCID: PMC9152371 DOI: 10.1155/2022/6807700] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 02/04/2022] [Accepted: 03/30/2022] [Indexed: 11/18/2022]
Abstract
Acute kidney injury (AKI) is a complex condition which has an intricate pathology mostly involving hemodynamic, inflammatory, and direct toxic effects at the cellular level with high morbidity and mortality ratios. Renal ischemic reperfusion injury (RIRI) is the main factor responsible for AKI, most often observed in different types of shock, kidney transplantation, sepsis, and postoperative procedures. The RIRI-induced AKI is accompanied by increased reactive oxygen species generation together with the activation of various inflammatory pathways. In this context, plant-derived medicines have shown encouraging nephroprotective properties. Evidence provided in this systemic review leads to the conclusion that plant-derived extracts and compounds exhibit nephroprotective action against renal ischemic reperfusion induced-AKI by increasing endogenous antioxidants and decreasing anti-inflammatory cytokines. However, there is no defined biomarker or target which can be used for treating AKI completely. These plant-derived extracts and compounds are only tested in selected transgenic animal models. To develop the results obtained into a therapeutic entity, one should apply them in proper vertebrate multitransgenic animal models prior to further validation in humans.

Antifungal activity and potential mechanism of magnoflorine against Trichophyton rubrum. J Antibiot (Tokyo) 2020; 74:206-214. [PMID: 33082529 DOI: 10.1038/s41429-020-00380-4] [Citation(s) in RCA: 18] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/09/2020] [Revised: 09/30/2020] [Accepted: 10/01/2020] [Indexed: 11/09/2022]
Abstract
Coptis alkaloids show potent antifungal activity against Trichophyton rubrum (T. rubrum), which was a Tinea pedis fungus, but little of the literature was reported to investigate the antifungal activity of magnoflorine against it. Meanwhile, the potential mechanism of magnoflorine against T. rubrum is unknown. In the present study, we found that Coptis alkaloids, especially magnoflorine had significant antifungal activities against T. rubrum and Trichophyton mentagrophyte (T. mentagrophyte). The MIC values of magnoflorine against T. rubrum and T. mentagrophyte were both 62.5 μg ml-1, but magnoflorine exerted a better fungicidal efficiency against T. rubrum than T. mentagrophyte. Magnoflorine inhibited the conidia germination and hyphal growth, and changed the mycelial morphology such as deformation growth, surface peeling, and cytoplasmic contraction in T. rubrum. Magnoflorine had no significant effect on cell wall integrity. However, magnoflorine destroyed the fungal cell membrane of T. rubrum through increasing the nucleic acid leakage, reducing the activities of squalene epoxidase and CYP51 enzyme, and decreasing the content of ergosterol in hyphae. Our study supported the potential use of magnoflorine as an antifungal agent against T. rubrum and made contributions to the clinical application of magnoflorine against fungi.

Anti-inflammatory and nephroprotective activity of Juglans mollis against renal ischemia-reperfusion damage in a Wistar rat model. Altern Ther Health Med 2019; 19:186. [PMID: 31349827 PMCID: PMC6660964 DOI: 10.1186/s12906-019-2604-7] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/30/2018] [Accepted: 07/19/2019] [Indexed: 12/19/2022]
Abstract
BACKGROUND Oxidative stress and the inflammatory process are involved in ischemia-reperfusion (I/R) injury. Juglans mollis has been reported as having antioxidant activity, which could attenuate the damage caused by I/R. We evaluated whether a methanolic extract of Juglans mollis (JM) exhibits nephroprotective activity in a Wistar rat model of I/R injury. METHODS Four groups of six rats were used: Sham, I/R, JM, and JM + I/R. Two groups were dosed with JM (300 mg/kg) for 7 days before I/R. I/R injury was induced by clamping the renal hilums for 45 min and then reperfusing the kidneys for 15 h. Blood samples were taken to evaluate the levels of alanine aminotransferase (ALT), blood urea nitrogen, creatinine, superoxide dismutase (SOD), malondialdehyde (MDA), interleukin 1β (IL-1β), IL-6, and tumor necrosis factor α (TNF-α). RESULTS The levels of creatinine, ALT, MDA, IL-1β, IL-6, and TNF-α were lower in JM + I/R than in I/R rats, whereas SOD level only was higher in JM + I/R than in Sham rats. No biochemical or histological damage was observed in JM rats compared with Sham rats; however, less histological damage was observed in JM + I/R rats compared with I/R rats. CONCLUSIONS To our knowledge, this is the first report of nephroprotective activity of J. mollis against damage induced by I/R. This activity may be related to decreased levels of proinflammatory cytokines (IL-1β, IL-6, and TNF-α) and modulation of oxidative stress markers (SOD and MDA) observed in the present study.

JOURNAL OF ETHNOPHARMACOLOGY 2017; 202:265-280. [PMID: 28330724 DOI: 10.1016/j.jep.2017.03.030] [Citation(s) in RCA: 17] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/01/2016] [Revised: 03/14/2017] [Accepted: 03/18/2017] [Indexed: 06/06/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Yujin Powder (YJP), an old prescription, is one of the most classical prescription for treating the large intestine dampness-heat syndrome (LIDHS). However, its potential modern pharmacological mechanisms remain unclear. AIM OF THE STUDY The present study was designed to explore the essence of LIDHS and treatment mechanisms of the YJP on the LIDHS. METHODS The rat model of LIDHS was established by such complex factors as high-sugar and high-fat diet, improper diet, high temperature and humidity environment (HTHE), drinking and intraperitoneal injection of Escherichia coli., which imitated the inducing conditions of LIDHS. Then the clinical symptoms and signs, blood routine, blood biochemistry, whole blood viscosity (WBV), serum inflammatory cytokines levels and the histopathological changes of main organs were detected and observed, respectively. RESULTS The results showed that the clinical symptoms and signs of the model rats were consistent with the diagnostic criteria of LIDHS, moreover, there were obvious systemic inflammatory response and extensive congestion. And after treatment with YJP in different dosages, the clinical symptoms and signs of the rats with LIDHS were improved; the indexes of blood routine and blood biochemistry and inflammatory cytokines levels tended to be normal; the WBV decreased and histopathological changes of major organs were alleviated or returned to normal. There was an obvious dose-effect relationship, and the high dose of YJP (HD-YJP) had the best treatment effects. CONCLUSIONS These results suggested that in LIDHS, diarrhea was the major clinical manifestation; the large intestine was the main lesion area; mucosa injury, inflammation and congestion of the large intestine with systemic inflammatory response and congestion were the most typical pathological characteristics. Meanwhile, YJP exhibited the comprehensive effects of anti-diarrhea, anti-inflammation, lowering blood lipid, relieving blood stasis, repairing intestinal mucosa and regulation and protection of multiple organs on LIDHS. These findings provided not only important information for understanding the essence of LIDHS but also the theoretical basis for developing new-drugs for treating dampness-heat type of diarrheal diseases.

Abstract
Microcirculation dysfunction and organ injury after ischemia and reperfusion (I/R) result from a complex pathologic process consisting of multiple links, with metabolism impairment in the ischemia phase and oxidative stress in the reperfusion phase as initiators, and any treatment targeting a single link is insufficient to cope with this. Compound Chinese medicine (CCM) has been applied in clinics in China and some Asian nations for >2000years. Studies over the past decades revealed the protective and therapeutic effect of CCMs and major ingredients on I/R-induced microcirculatory dysfunction and tissue injury in the heart, brain, liver, intestine, and so on. CCM contains diverse bioactive components with potential for energy metabolism regulation; antioxidant effect; inhibiting inflammatory cytokines release; adhesion molecule expression in leukocyte, platelet, and vascular endothelial cells; and the protection of thrombosis, albumin leakage, and mast cell degranulation. This review covers the major works with respect to the effects and underlying mechanisms of CCM and its ingredients on microcirculatory dysfunction and organ injury after I/R, providing novel ideas for dealing with this threat.

Abstract
AIM: To investigate the effects of San-Huang-Xie-Xin-Tang (SHXXT), a herbal product used in traditional Chinese medicine, on gastrointestinal (GI) motility in mice.
METHODS: The in vivo effects of SHXXT on GI motility were investigated by measuring the intestinal transit rates (ITRs) using Evans blue in normal mice and in mice with experimentally induced GI motility dysfunction (GMD).
RESULTS: In normal ICR mice, ITRs were significantly and dose-dependently increased by SHXXT (0.1-1 g/kg). GMD was induced by injecting acetic acid or streptozotocin intraperitoneally. The ITRs of GMD mice were significantly reduced compared to normal mice, and these reductions were significantly and dose-dependently inhibited by SHXXT (0.1-1 g/kg).
CONCLUSION: These results suggest that SHXXT is a novel candidate for the development of a prokinetic agent that may prevent or alleviate GMD.

Abstract
Berberine is an isoquinoline alkaloid present in several plant species, including Coptis sp. and Berberis sp. In traditional medicine, extracts of berberine are used in the treatment of diarrhea of different origins. Recent studies have shown that berberine and its derivatives have significant biological effects on gastrointestinal (GI) and other functions and may become therapeutics for the treatment of diarrhea, gastroenteritis, diabetes, hyperlipidemia, cardiovascular diseases and inflammatory conditions. This paper summarizes the current knowledge on the actions of berberine in the GI tract. Binding and target sites, activated intracellular pathways, as well as the absorption and metabolism of berberine are discussed. Effects that may be useful in future clinical treatment, like antidiarrheal, anti-inflammatory and antitumor effects are critically reviewed and potential clinical applications are presented in detail.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Coptidis rhizoma is traditionally used for heat-clearing and toxic-scavenging and it belongs to liver meridian in Chinese medicine practice. Clinically, Coptidis rhizoma can be used for hepatic and biliary disorders, yet details in the therapies of liver diseases and underlying mechanism(s) remain unclear. Our previous study demonstrated that Coptidis rhizoma aqueous extract (CRAE) against CCl(4)-induced acute liver damage was related to antioxidant property. In the present study, the protection of CRAE on chronic liver damage induced by carbon tetrachloride (CCl(4)) in rats and its related mechanism were explored. MATERIALS AND METHODS The CCl(4)-induced chronic liver damage model was established, and CRAE's protective effect was examined. Serum aspartate aminotransferase (AST) and alanine aminotransferase (ALT) activity, serum and liver superoxide dismutase (SOD) activity were then measured. The histological changes were observed under microscopy and then computed in numerical score. The normal or damaged cells were isolated and related signaling pathway was evaluated. RESULT Serum AST and ALT activities were significantly decreased in rats treated with different doses of CRAE, indicating its protective effect against CCl(4)-induced chronic liver damage. Observation on serum SOD activity revealed that CRAE might act as an anti-oxidant agent against CCl(4)-induced chronic oxide stress. Histological study supported these observations. Erk1/2 inhibition may take part into CRAE's effect on preventing hepatocyte from apoptosis when exposed to oxidative stress. CONCLUSION CRAE showed protective effect against CCl(4)-induced chronic liver damage in rats and its potential as an agent in the treatment of chronic liver diseases by protecting hepatocyte from injury.

Abstract
Abstract
A study was conducted to elucidate and compare the protective activity of alkaloids from Coptidis Rhizoma (berberine, coptisine, palmatine, epiberberine, jatrorhizine, groenlandicine and magnoflorine) using an LLC-PK1 cell under peroxynitrite (ONOO−) generation model. Treatment with 3-morpholino-sydnonimine (SIN-1) led to an increase in cellular ONOO− generation in comparison with non-treated cells. However, Coptidis Rhizoma extract and its alkaloids, except for berberine, reduced the cellular ONOO− level. In addition, DNA fragmentation induced by SIN-1 was significantly decreased by the extract, and also by coptisine, epiberberine, jatrorhizine, groenlandicine and magnoflorine. Moreover, treatment with berberine, coptisine, palmatine and epiberberine exerted a protective effect against G0/G1 phase arrest of cell cycle induced by SIN-1. The increase in cellular ONOO− generation, DNA damage and disturbance of the cell cycle by SIN-1 resulted in a decrease in cell viability. However, Coptidis Rhizoma extract, epiberberine, jatrorhizine, groenlandicine and magnoflorine significantly increased cell viability even at a concentration as low as 10μg mL−1. These findings demonstrate that Coptidis Rhizoma extract and its alkaloids can ameliorate the cell damage associated with ONOO− generation in renal tubular LLC-PK1 cells, and that the various alkaloids have distinctive mechanisms of action, such as ONOO− scavenging, protection from DNA damage and control of the cell cycle. Furthermore, the data suggest that among the Coptidis Rhizoma alkaloids, coptisine is the most effective for protection against SIN-1-induced cellular injury in terms of its potency and content.

Abstract
Traditional Chinese medicine (TCM) has been used for thousands of years. Most Chinese herbal formulae consist of several herbal components and have been used to treat various diseases. However, the mechanisms of most formulae and the relationship between formulae and their components remain to be elucidated. Here we analyzed the putative mechanism of San-Huang-Xie-Xin-Tang (SHXXT) and defined the relationship between SHXXT and its herbal components by microarray technique. HepG2 cells were treated with SHXXT or its components and the gene expression profiles were analyzed by DNA microarray. Gene set enrichment analysis indicated that SHXXT and its components displayed a unique anti-proliferation pattern via p53 signaling, p53 activated, and DNA damage signaling pathways in HepG2 cells. Network analysis showed that most genes were regulated by one molecule, p53. In addition, hierarchical clustering analysis showed that Rhizoma Coptis shared a similar gene expression profile with SHXXT. These findings may explain why Rhizoma Coptis is the principle herb that exerts the major effect in the herbal formula, SHXXT. Moreover, this is the first report to reveal the relationship between formulae and their herbal components in TCM by microarray and bioinformatics tools.

Abstract
Renal ischemia-reperfusion (I-R) contributes to the development of ischemic acute renal failure (ARF). Multi-factorial processes are involved in the development and progression of renal I-R injury with the generation of reactive oxygen species, nitric oxide and peroxynitrite, and the decline of antioxidant protection playing major roles, leading to dysfunction, injury, and death of the cells of the kidney. Renal inflammation, involving cytokine/adhesion molecule cascades with recruitment, activation, and diapedesis of circulating leukocytes is also implicated. Clinically, renal I-R occurs in a variety of medical and surgical settings and is responsible for the development of acute tubular necrosis (a characteristic feature of ischemic ARF), e.g., in renal transplantation where I-R of the kidney directly influences graft and patient survival. The cellular mechanisms involved in the development of renal I-R injury have been targeted by several pharmacological interventions. However, although showing promise in experimental models of renal I-R injury and ischemic ARF, they have not proved successful in the clinical setting (e.g., atrial natriuretic peptide, low-dose dopamine). This review highlights recent pharmacological developments, which have shown particular promise against experimental renal I-R injury and ischemic ARF, including novel antioxidants and antioxidant enzyme mimetics, nitric oxide and nitric oxide synthase inhibitors, erythropoietin, peroxisome-proliferator-activated receptor agonists, inhibitors of poly(ADP-ribose) polymerase, carbon monoxide-releasing molecules, statins, and adenosine. Novel approaches such as recent research involving combination therapies and the potential of non-pharmacological strategies are also considered.
