Abstract
Chronic kidney disease (CKD) is a chronic and progressive systemic condition that characterizes irreversible alterations in the kidneys' function and structure over an extended period, spanning months to years. CKD is the one of the major causes of mortality worldwide. However, very limited treatment options are available in the market for management of the CKD. Diabetes and hypertension are the key risk factors for the progression of CKD. It is majorly characterised by glomerulosclerosis, tubular atrophy, and interstitial fibrosis. Plants are considered safe and effective in treating various chronic conditions. A diverse group of phytoconstituents, including polyphenols, flavonoids, alkaloids, tannins, saponins, and terpenes, have found significant benefits in managing chronic ailments. Terpenes constitute a diverse group of plant compounds with various therapeutic benefits. Evidence-based pharmacological studies underscore the crucial role played by terpenes in preventing and managing CKD. These substances demonstrate the capacity to hinder detrimental pathways, such as oxidative stress, inflammation and fibrosis, thereby demonstrating benefit in renal dysfunction. This review offers a comprehensive overview of the roles and positive attributes of commonly occurring terpenes in managing the causes and risk factors of CKD and the associated conditions.

Abstract
Diabetes mellitus is a common metabolic disorder. About two-thirds of diabetic patients develop diabetic cardiomyopathy (DCM), which becomes a challenging issue as it severely threatens the patient's life. Hyperglycemia and the resulting advanced glycated end products (AGE) and their receptor (RAGE)/High Mobility Group Box-1 (HMGB-1) molecular pathway are thought to be key players. Recently, artemisinin (ART) has gained more attention owing to its potent biological activities beyond its antimalarial effect. Herein, we aim to evaluate the effect of ART on DCM and the possible underlying mechanisms. Twenty-four male Sprague-Dawley rats were divided into: control, ART, type 2 diabetic and type 2 diabetic treated with ART groups. At the end of the research, the ECG was recorded, then the heart weight to body weight (HW/BW) ratio, fasting blood glucose, serum insulin and HOMA-IR were evaluated. Cardiac biomarkers (CK-MB and LDH), oxidative stress markers, IL-1β, AGE, RAGE and HMGB-1 expression were also measured. The heart specimens were stained for H&E as well as Masson's trichrome. DCM induced disturbances in all studied parameters; contrary to this, ART improved these insults. Our study concluded that ART could improve DCM through modulation of the AGE-RAGE/HMGB-1 signaling pathway, with subsequent impacts on oxidative stress, inflammation and fibrosis. ART could therefore be a promising therapy for the management of DCM.

Abstract
Artemisinin, an antimalarial traditional Chinese herb, is isolated from Artemisia annua. L, and has shown fewer side effects. Several pieces of evidence have demonstrated that artemisinin and its derivatives exhibited therapeutic effects on diseases like malaria, cancer, immune disorders, and inflammatory diseases. Additionally, the antimalarial drugs demonstrated antioxidant and anti-inflammatory activities, regulating the immune system and autophagy and modulating glycolipid metabolism properties, suggesting an alternative for managing kidney disease. This review assessed the pharmacological activities of artemisinin. It summarized the critical outcomes and probable mechanism of artemisinins in treating kidney diseases, including inflammatory, oxidative stress, autophagy, mitochondrial homeostasis, endoplasmic reticulum stress, glycolipid metabolism, insulin resistance, diabetic nephropathy, lupus nephritis, membranous nephropathy, IgA nephropathy, and acute kidney injury, suggesting the therapeutic potential of artemisinin and its derivatives in managing kidney diseases, especially the podocyte-associated kidney diseases.

Protective Effect and Possible Mechanisms of Artemisinin and Its Derivatives for Diabetic Nephropathy: A Systematic Review and Meta-Analysis in Animal Models. OXIDATIVE MEDICINE AND CELLULAR LONGEVITY 2022; 2022:5401760. [PMID: 35528521 PMCID: PMC9073547 DOI: 10.1155/2022/5401760] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 02/02/2022] [Accepted: 04/04/2022] [Indexed: 11/25/2022]
Abstract
Background Artemisinin and its derivatives have potential antidiabetic effects. There is no evaluation of reported studies in the literature on the treatment of diabetic nephropathy (DN), one of the commonest diabetic microangiopathies, with artemisinins. Here, we aimed to evaluate preclinical evidence for the efficacy and possible mechanisms of artemisinins in reducing diabetic renal injury. Methods We conducted an electronic literature search in fourteen databases from their inception to November 2021. All animal studies assessing the efficacy and safety of artemisinins in DN were included, regardless of publication or language. Overall, 178 articles were screened according to predefined inclusion and exclusion criteria. Finally, 18 eligible articles were included in this systematic review. The SYstematic Review Center for Laboratory animal Experimentation (SYRCLE) risk-of-bias tool was used to assess the risk of bias in the included studies. The primary outcomes were kidney function, proteinuria, and renal pathology. Secondary endpoints included changes in fasting plasma glucose (FPG) levels, body weight, and relevant mechanisms. Results Of the 18 included articles involving 418 animal models of DN, 1, 2, 6, and 9 used dihydroartemisinin, artemether, artesunate, and artemisinin, respectively. Overall, artemisinins reduced indicators of renal function, including blood urea nitrogen (P < 0.00001), serum creatinine (P < 0.00001), and kidney index (P = 0.0001) compared with control group treatment. Measurements of proteinuria (P < 0.00001), microalbuminuria (P < 0.05), and protein excretion (P = 0.0002) suggested that treatment with artemisinins reduced protein loss in animals with DN. Artemisinins may lower blood glucose levels (P = 0.01), but there is a risk of weight gain (P < 0.00001). Possible mechanisms of action of artemisinins include delaying renal fibrosis, reducing oxidative stress, and exerting antiapoptotic and anti-inflammatory effects. Conclusion Available evidence suggests that artemisinins may be protective against renal injury secondary to diabetes in preclinical studies; however, high-quality and long-term trials are needed to reliably determine the balance of benefits and harms.

Abstract
Although current evidence suggests that artemisinin and its derivatives play a multitarget therapeutic role in type 2 diabetes mellitus (T2DM), their efficacy and safety remain under debate. This meta-analysis aimed to evaluate the effects and safety of artemisinin and its derivatives in T2DM animal models. Preclinical studies that met the inclusion criteria were retrieved from PubMed, Embase, Web of Science, Scopus, CINAHL, OpenGrey, Google Scholar, Psyclnfo, British Library Ethos, ProQuest Dissertations & Theses, China National Knowledge Internet, VIP Information Chinese Periodical Service Platform, Chinese Biomedicine Literature Database, and Wanfang Data Knowledge Service Platform. Twenty-two studies involving 526 animals were included in the meta-analysis. The RevMan 5.3 and Stata 15.0, were used to perform the statistical analyses. The overall results showed that artemisinin or its derivatives could significantly reduce fasting plasma glucose, 2-h plasma glucose (2hPG) in the intraperitoneal glucose tolerance test (IPGTT), 2hPG in the intraperitoneal insulin tolerance test (IPITT), glycated hemoglobin A1c, under the curve in the IPGTT/IPITT, total cholesterol, triglyceride, low-density lipoprotein cholesterol, free fatty acid, and urine volume. Although increase in body weight was observed due to administration of the compounds, no significant effect was observed regarding serum insulin. In terms of adverse reactions, only two of the included studies reported that high-dose artemether may cause digestive inhibition in mice. Our results suggest that artemisinins could improve several parameters related to glycolipid metabolism in T2DM animal models. However, to evaluate the antidiabetic effects and safety of artemisinins in a more accurate manner, additional preclinical studies are necessary.

Abstract
Diabetic nephropathy (DN) is one of the manifestations of systemic microangiopathy in diabetes. Trifolium alexandrinum extract (TAE) contains biologically active phenolic compounds such as hesperetin (HES) and quercetin, possess various pharmacological properties, including anti-inflammatory, and anti-oxidative potentials. The present study aimed to assess the therapeutic effects and mechanisms underlying the anti-diabetic, antioxidant, and anti-inflammatory effects of HES and quercetin extracted from TAE, and TAE in STZ-induced DN. Male albino rats (170 ± 10 g) were divided into group (1); control rats and groups (2-5); diabetic/HFD were intraperitoneal (i.p.) injected with STZ (35 mg/kg), diabetic rats were randomly classified into STZ, STZ + HES (40 mg/kg), STZ + quercetin (50 mg/kg), and STZ + TAE (200 mg/kg) groups. After 5 weeks, blood and kidney samples were collected for further biochemical, western blotting and histopathological studies. Serum renal functions, renal oxidative status biomarkers and proinflammatory cytokines were determined. The results revealed that there were significant increases in urea, BUN, creatinine, ALP, total protein, albumin, and globulin with a significant decrease in Na+ and K+ levels, as well as significant elevation in TBARS, TGF-β, TNF-α, IL-6 and the expression levels of GSK-3β, as well as significant decline in TAC, GSH and CAT levels in STZ-treated group compared to the control rats. The previous deleterious alterations were significantly ameliorated after the treatment of diabetic rats with HES, quercetin and TAE. In conclusion, our data demonstrated that HES, quercetin and TAE could be used as potent therapeutic agents to counter DN through antioxidant, anti-inflammatory, and antidiabetic effects.

Abstract
Fibrosis is a pathological reparative process that can occur in most organs and is responsible for nearly half of deaths in the developed world. Despite considerable research, few therapies have proven effective and been approved clinically for treatment of fibrosis. Artemisinin compounds are best known as antimalarial therapeutics, but they also demonstrate antiparasitic, antibacterial, anticancer, and anti-fibrotic effects. Here we summarize literature describing anti-fibrotic effects of artemisinin compounds in in vivo and in vitro models of tissue fibrosis, and we describe the likely mechanisms by which artemisinin compounds appear to inhibit cellular and tissue processes that lead to fibrosis. To consider alternative routes of administration of artemisinin for treatment of internal organ fibrosis, we also discuss the potential for more direct oral delivery of Artemisia plant material to enhance bioavailability and efficacy of artemisinin compared to administration of purified artemisinin drugs at comparable doses. It is our hope that greater understanding of the broad anti-fibrotic effects of artemisinin drugs will enable and promote their use as therapeutics for treatment of fibrotic diseases.

Abstract
Type 2 diabetes mellitus (T2DM) is a chronic disease that has become a global public health problem. Studies on T2DM prevention and treatment mostly focus on discovering therapeutic drugs. Artemisinin and its derivatives were originally used as antimalarial treatments. In recent years, the roles of artemisinins in T2DM have attracted much attention. Artemisinin treatments not only attenuate insulin resistance and restore islet ß-cell function in T2DM but also have potential therapeutic effects on diabetic complications, including diabetic kidney disease, cognitive impairment, diabetic retinopathy, and diabetic cardiovascular disease. Many in vitro and in vivo experiments have confirmed the therapeutic utility of artemisinin and its derivatives on T2DM, but no article has systematically demonstrated the specific role artemisinin plays in the treatment of T2DM. This review summarizes the potential therapeutic effects and mechanism of artemisinin and its derivatives in T2DM and associated complications, providing a reference for subsequent related research.

Artemisinin attenuates early renal damage on diabetic nephropathy rats through suppressing TGF-β1 regulator and activating the Nrf2 signaling pathway. Life Sci 2020; 256:117966. [PMID: 32535079 DOI: 10.1016/j.lfs.2020.117966] [Citation(s) in RCA: 12] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/26/2020] [Revised: 06/06/2020] [Accepted: 06/09/2020] [Indexed: 12/17/2022]
Abstract
AIM The present study aims to investigate the protective effects of artemisinin (ATZ) on early renal damage in experimental diabetic rats and its probable mechanism. METHODS Models of diabetic nephropathy (DN) rats was established utilizing streptozotocin (STZ)-injection intraperitoneally (55 mg/kg) method. All rats were subsequently divided into normal control group, model group and ATZ (25, 50, 75 mg/kg) group randomly. Biochemical parameters including body weight, kidney index, blood glucose, 24 h UAER, Scr, BUN, T-SOD, GSH-Px and MDA were comprehensively determined after 8-week consecutive administrations. HE and PAS stainings were performed to observe the histopathological alterations of kidney. Western blot was conducted to detect the expressions of TGF-β1, Nrf2, HQ-1 and NQO1. KEY FINDINGS ATZ at three concentrations in ATZ group significantly increased the body weight. Biochemical parameters altered significantly between model group and ATZ group. Moreover, ATZ inhibited TGF-β1 protein expression and activated the Nrf2 signaling pathway. Pathological histology results revealed the alterations including mesangial cells proliferation, thickness of glomerular capillary basement membrane, extracellular matrix (ECM) and the 24 h UAER. Western blot analysis demonstrated the increase of antioxidant proteins HO-1 and NQO1 and Nrf2-related proteins. SIGNIFICANCE ATZ could reduce early renal oxidative stress damage in DN rats by inhibiting TGF-β1 protein expression in kidney tissues as well as activating the Nrf2 signaling pathway and enhancing the expression of antioxidant proteins, thereby exerting the protective effects on DN kidney. The current study is the first report of ATZ on attenuating effects on kidney of DN rats, which could lay solid theoretical foundations on clinical application of ATZ to treat DN.

Abstract
BACKGROUND Single-cell RNA-seq (scRNA-seq) is emerging as a powerful tool to dissect cell-specific effects of drug treatment in complex tissues. This application requires high levels of precision, robustness, and quantitative accuracy-beyond those achievable with existing methods for mainly qualitative single-cell analysis. Here, we establish the use of standardized reference cells as spike-in controls for accurate and robust dissection of single-cell drug responses. RESULTS We find that contamination by cell-free RNA can constitute up to 20% of reads in human primary tissue samples, and we show that the ensuing biases can be removed effectively using a novel bioinformatics algorithm. Applying our method to both human and mouse pancreatic islets treated ex vivo, we obtain an accurate and quantitative assessment of cell-specific drug effects on the transcriptome. We observe that FOXO inhibition induces dedifferentiation of both alpha and beta cells, while artemether treatment upregulates insulin and other beta cell marker genes in a subset of alpha cells. In beta cells, dedifferentiation and insulin repression upon artemether treatment occurs predominantly in mouse but not in human samples. CONCLUSIONS This new method for quantitative, error-correcting, scRNA-seq data normalization using spike-in reference cells helps clarify complex cell-specific effects of pharmacological perturbations with single-cell resolution and high quantitative accuracy.

Abstract
Artemisinin (ARS) and its derivatives (ARSs) are recommended as the first-line antimalarial drugs for the treatment of malaria. Besides antimalarial function, its potent anti-inflammatory and immunoregulatory properties, as well as the ability to regulate oxidative stress have brought them to a prominent position. As researchers around the world are continually exploring the unknown biological activities of ARS derivatives, experimental studies have shown much progress in renal therapy. This review aims to give a brief overview of the current research on ARSs applications for kidney treatment with the evaluation of therapeutic properties and potential molecular mechanisms.

Abstract
Artemisia annua is an important medicinal plant producing the majority of the antimalarial compound artemisinin. Jasmonates are potent inducers of artemisinin accumulation in Artemisisa annua plants. As the receptor of jasmonates, the F-box protein COI1 is critical to the JA signaling required for plant development, defense, and metabolic homeostasis. AaCOI1 from Artemisia annua, homologous to Arabidopsis AtCOI1, encodes a F-box protein located in the nuclei. Expressional profiles of the AaCOI1 in the root, stem, leaves, and inflorescence was investigated. The mRNA abundance of AaCOI1 was the highest in inflorescence, followed by in the leaves. Upon mechanical wounding or MeJA treatment, expression of AaCOI1 was upregulated after 6 h. When ectopically expressed, driven by the native promoter from Arabidopsis thaliana, AaCOI1 could partially complement the JA sensitivity and defense responses, but fully complemented the fertility, and the JA-induced anthocyanin accumulation in a coi1-16 loss-of-function mutant. Our study identifies the paralog of AtCOI1 in Artemisia annua, and revealed its implications in development, hormone signaling, defense, and metabolism. The results provide insight into JA perception in Artemisia annua, and pave the way for novel molecular breeding strategies in the canonical herbs to manipulate the anabolism of pharmaceutic compounds on the phytohormonal level.
