Mehdi S, Mehmood MH, Ahmed MG, Ashfaq UA. Antidiabetic activity of Berberis brandisiana is possibly mediated through modulation of insulin signaling pathway, inflammatory cytokines and adipocytokines in high fat diet and streptozotocin-administered rats. Front Pharmacol 2023; 14:1085013. [PMID: 37089941 PMCID: PMC10117783 DOI: 10.3389/fphar.2023.1085013] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/31/2022] [Accepted: 03/22/2023] [Indexed: 04/25/2023] Open
Abstract
Medicinal plants play a key role in protection of chronic non-communicable ailments like diabetes, hypertension and dyslipidemia. Berberis brandisiana Ahrendt (Berberidaceae) is traditionally used to treat diabetes, liver problems, wounds, arthritis, infections, swelling and tumors. It is also known to be enriched with multiple phytoconstituents including berbamine, berberine, quercetin, gallic acid, caffeic acid, vanillic acid, benzoic acid, chlorogenic acid, syringic acid, p-coumaric acid, m-coumaric acid and ferulic acid. The efficacy of B. brandisiana has not been established yet in diabetes. This study has been planned to assess the antidiabetic activity of B. brandisiana in high fat diet and streptozotocin (HFD/STZ)-induced diabetes using animals. Administration of aqueous methanolic extract of B. brandisiana (AMEBB) and berbamine (Berb) for 8 weeks caused a dose dependent marked (p < 0.01) rise in serum insulin and HDL levels with a significant decline (p < 0.01) in glucose, triglycerides, glycosylated hemoglobin (HbA1c), cholesterol, LDL, LFTs and RFTs levels when compared with only HFD/STZ-administered rats. AMEBB and Berb also modulated inflammatory biomarkers (TNF-α, IL-6) and adipocytokines (leptin, adiponectin and chemerin). AMEBB (150 mg/kg and 300 mg/kg) and Berb (80 mg/kg and 160 mg/kg) treated rats showed a marked increase (p < 0.001) in catalase levels (Units/mg) in pancreas (42.4 ± 0.24, 47.4 ± 0.51), (38.2 ± 0.583, 48.6 ± 1.03) and liver (52 ± 1.41, 63.2 ± 0.51), (57.2 ± 0.58, 61.6 ± 1.24) and superoxide dismutase levels (Units/mg) in pancreas (34.8 ± 1.46, 38.2 ± 0.58), (33.2 ± 0.80, 40.4 ± 1.96) and liver (31.8 ± 1.52, 36.8 ± 0.96), (30 ± 0.70, 38.4 ± 0.81),respectively while a significant (p < 0.01) decrease in serum melondialdehyde levels (nmol/g) in pancreas (7.34 ± 0.17, 6.22 ± 0.22), (7.34 ± 0.20, 6.34 ± 0.11) and liver (9.08 ± 0.31,8.18 ± 0.29), (9.34 ± 0.10, 8.86 ± 0.24) compared to the data of only HFD/STZ-fed rats. Histopathological studies of pancreas, liver, kidney, heart and aorta revealed restoration of normal tissue architect in AMEBB and Berb treated rats. When mRNA expressions of candidate genes were assessed, AMEBB and Berb showed upregulation of IRS-1, SIRT1, GLUT-4 and downregulation of ADAM17. These findings suggest that AMEBB and Berb possess antidiabetic activity, possibly due to its effect on oxidative stress, glucose metabolism, inflammatory biomarkers and adipocytokines levels. Further upregulation of IRS-1, SIRT1, GLUT-4 and downregulation of ADAM17, demonstrated its potential impact on glucose homeostasis, insulin resistance and chronic inflammatory markers. Thus, this study provides support to the medicinal use of B. brandisiana and berbamine in diabetes.

Int J Biol Macromol 2022; 223:378-390. [PMID: 36368355 DOI: 10.1016/j.ijbiomac.2022.11.055] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/30/2022] [Revised: 11/05/2022] [Accepted: 11/07/2022] [Indexed: 11/10/2022]
Abstract
In this study, the synergistic effects of black onion on the hypolipidemic and antioxidant activities in T2DM rats induced by a high-fat-diet and alloxan were investigated. The results showed that the fasting blood glucose of diabetic rats was significantly decreased after treatment with black onion polysaccharide (p < 0.01). Blood lipid analysis indicated that black onion polysaccharide could significantly improve the abnormal metabolism of blood lipids caused by diabetes. In addition, the MDA and ROS of the diabetic rats treated with black onion polysaccharide were significantly reduced; moreover, SOD was increased, indicating the excellent antioxidant activity of black onion polysaccharide. A histological examination clearly showed that black onion polysaccharide could improve the histological morphology of the liver and kidney. Furthermore, the indices of liver and kidney function were restored. These results indicate that black onion polysaccharide can reduce blood glucose and simultaneously show synergistic effects of hypoglycemic and antioxidant activities in diabetic rats. Therefore, black onion polysaccharide may alleviate liver and kidney function injury by improving the "two-hit" mechanism and can thus be used as a potential functional food to prevent diabetes and its complications.

Abstract
In this study, we attempted for the first time to determine the phytochemical compositions and biopharmaceutical properties of Globularia alypum methanol extract (GAME) and Globularia alypum water extract (GAWE). High-performance liquid chromatography with diode array detection (HPLC-DAD) analysis was performed to establish the chemical profile of the investigated extracts. Chemical composition analysis was taken in the presence of various bioactive compounds such as quercetin 7-O-glucoside and apigenin 7-O-glucoside in GAME. In GAWE, various abundant compounds were found in the extract such as quercetin 7-O-glucoside, apigenin, quercetin, apigenin 7-O-glucoside, and cinnamic acid. This study showed that the administration of GAWE and GAME to type 1 diabetic rats decreased fasting blood glucose, protected pancreas β-cells from death and injury, increased liver glycogen rate, and ameliorated oral glucose tolerance test. Moreover, GA reduced weight loss, and diabetes decreased basic physical activity. In addition, the administration of GA extracts in diabetic rats protected from diabetes-induced liver, kidney, testes, heart, and bone toxicities. Conclusion. GAWE has possible value for antidiabetic oral medication.

Abstract
Diabetes mellitus is a chronic complication that affects people of all ages. The increased prevalence of diabetes worldwide has led to the development of several synthetic drugs to tackle this health problem. Such drugs, although effective as antihyperglycemic agents, are accompanied by various side effects, costly, and inaccessible to the majority of people living in underdeveloped countries. Medicinal plants have been used traditionally throughout the ages to treat various ailments due to their availability and safe nature. Medicinal plants are a rich source of phytochemicals that possess several health benefits. As diabetes continues to become prevalent, health care practitioners are considering plant-based medicines as a potential source of antidiabetic drugs due to their high potency and fewer side effects. To better understand the mechanism of action of medicinal plants, their active phytoconstituents are being isolated and investigated thoroughly. In this review article, we have focused on pharmacologically active phytomolecules isolated from medicinal plants presenting antidiabetic activity and the role they play in the treatment and management of diabetes. These natural compounds may represent as good candidates for a novel therapeutic approach and/or effective and alternative therapies for diabetes.

Abstract
This study investigated the influence of dietary phenolic acid- Gallic acid (GA) on the antihyperglycemic properties of acarbose (ACA) and metformin (MET). Streptozotocin-induced diabetic rats were treated (p.o) with ACA, MET, GA and their combinations for 14 days. The effects of the treatments on blood glucose and insulin levels, pancreas α-amylase and intestinal α-glucosidase activities, as well as thiobarbituric acid reactive species (TBARS), thiol and reactive oxygen species (ROS) levels, including antioxidant enzyme activities were investigated. A significant increase in blood glucose, insulin, ROS and TBARS levels, and impaired antioxidant status, as well as elevation in the activities of α-amylase and α-glucosidase observed in diabetic rats were ameliorated in the treatment groups. Hpwever, GA had varying effects on the antidiabetic properties of the drugs. Nevertheless, GA showed more potentiating effects on the antidiabetic effect of MET and these effects were better observed at the lower dose of GA.

Abstract
It has been reported that fucoidan possesses anti-diabetic activities by inhibiting α-glucosidase activity, improving β-cell dysfunction, and enhancing insulin sensitivity. However, as a macromolecular carbohydrate, fucoidan is rarely absorbed and indigestible in gastrointestinal tract. The study aimed to explore whether the fucoidan can regulate glucose metabolism by improving intestinal barrier and inflammation in type 2 diabetes mellitus (T2DM) rats. A high-fat diet combined with streptozotocin was used to induce T2DM rats. Different doses of fucoidan (50, 100 and 200 mg/kg) were administered respectively by lavage to T2DM rats for 8 weeks and saline was given to controls. The results showed that in addition to hyperglycemia and hyperlipidemia, T2DM rats were also characterized by increased intestinal permeability and proinflammatory cytokines. Notably, fucoidan reduced fasting blood glucose and insulin resistance index along with alleviated the accumulation of proinflammatory cytokines in T2DM rats. Furthermore, fucoidan repaired the intestinal barrier function, which was accompanied by the up-regulation of tight junction proteins and the improvement of intestinal inflammation via inhibiting TLR4/NF-κB signaling. Meanwhile, fucoidan also mitigated the liver damage, and alleviated insulin resistance by activating PI3K/AKT signaling. Collectively, these findings supported the potential of fucoidan to be used as a functional ingredient to prevent T2DM.

Abstract
Small GTPase Rab8a is involved in fat-specific protein 27 (Fsp27) mediated lipid droplet accumulation in adipocytes. By screening inhibitors of Rab8a GTPase from a natural compound library, berbamine (BBM), a marketing drug for treatment of leukopenia in China, was identified to inhibit the activity of Rab8a GTPase and block the differentiation of 3T3-L1 adipocytes. Animal study showed that BBM could reduce body weight, improved glucose and lipid metabolic homeostasis in high-fat diet-induced obesity (DIO) C57BL/6 mice and db/db mice. Additional, BBM increased energy expenditure and inhibited food intake in mice but not in lean mice. Moreover, intracerebroventricular injection (i.c.v.) of BBM inhibited feeding behavior and increased c-Fos expression in paraventricular nucleus of the hypothalamus (PVH) of mice. Our data suggest that BBM may improve obesity through the inhibition of Rab8a GTPase activity and the activation of anorexigenic energy-sensing neuron in PVH.

Abstract
The kidneys are a vital organ that is vulnerable to both acute kidney injury (AKI) and chronic kidney disease (CKD) which can be caused by numerous risk factors such as ischemia, sepsis, drug toxicity and drug overdose, exposure to heavy metals, and diabetes. In spite of the advances in our understanding of the pathogenesis of AKI and CKD as well AKI transition to CKD, there is still no available therapeutics that can be used to combat kidney disease effectively, highlighting an urgent need to further study the pathological mechanisms underlying AKI, CKD, and AKI progression to CKD. In this regard, animal models of kidney disease are indispensable. This article reviews a widely used animal model of kidney disease, which is induced by folic acid (FA). While a low dose of FA is nutritionally beneficial, a high dose of FA is very toxic to the kidneys. Following a brief description of the procedure for disease induction by FA, major mechanisms of FA-induced kidney injury are then reviewed, including oxidative stress, mitochondrial abnormalities such as impaired bioenergetics and mitophagy, ferroptosis, pyroptosis, and increased expression of fibroblast growth factor 23 (FGF23). Finally, application of this FA-induced kidney disease model as a platform for testing the efficacy of a variety of therapeutic approaches is also discussed. Given that this animal model is simple to create and is reproducible, it should remain useful for both studying the pathological mechanisms of kidney disease and identifying therapeutic targets to fight kidney disease.

Abstract
Since ancient times the medicinal plants have been under use as food and potential therapeutic agent for the management of overall health and the use of all plant parts including fruits, seeds, is well reported in the literature. One such plant is Berberis aristata which is rich in vitamins, minerals, and various phytochemicals amongst which Berberine is the principal bioactive compound with a range of reported health benefits, and some of the commercial formulations like Rasaut, Darvyadi Leha are being used for the treatments of jaundice, malaria, typhoid fever, inflammation, eye infection, diarrhea, wound healing, etc. The hepatoprotective, antidiabetic, antitumor, anti-cancerous, properties are the recent additions to its functional importance. Berberine has significant bioactivities in the treatments of different diseases. Besides its remarkable applications, the berberine has low efficacy due to its low solubility in water, poor absorption, and low bioavailability. This problem can be solved by using some techniques like Nanotechnology which has been found to increase its solubility in water, bioavailability, and absorption and hence provide a better delivery system of berberine. This review illuminates the therapeutic applications of the plant Berberis aristata, scientific validation to its traditional uses, role of berberine in the treatment of various diseases through its different bioactivities, major flaws in berberine treatment, and the role of nanotechnology in minimizing those flaws and increasing its overall efficacy. Key teaching pointsPlant Berberis aristata has been used since ancient times for the treatment of various ailments like jaundice, hepatitis, fever, bleeding, inflammation, diarrhea, malaria, skin and eye infections, chronic rheumatism, and urinary disorders.Berberine is the major and most significant phytochemical among numerous phytochemicals present in plant Berberis aristata.Berberine has significantly shown many potent effect against emerging diseases like cancer and diabetes. Besides that, it has also shown antioxidant, anti-inflamation, antimicrobial, hepatoprotective, and anti-gastrointestinal disorder properties.Berberine can be very effective in overcoming the demerits of berberine treatment like poor aqueous solubility, low bioavailability, and poor absorption in the human body in the treatment of various diseases.

Abstract
Traditional medicinal plants have wide-reaching utilisation in the treatment of diabetes especially in developing countries where medical resources are meagre. Traditionally used anti-diabetic plants act by numerous mechanisms, however, only a few of them act through activation of the glucokinase enzyme. Glucokinase is a key regulatory enzyme in glucose metabolism thereby controls glucose homeostasis and insulin secretion. The present review significantly analyses the knowledge about various plant-based glucokinase activators including numerous phytochemicals which modulate the activity and gene expression of glucokinase and would provide data support and perspective regarding future research in the discovery and development of different plant-derived glucokinase activators.

Abstract
Non-alcoholic fatty liver disease (NAFLD), a chronic metabolic disorder is concomitant with oxidative stress and inflammation. This study aimed to assess the effects of berbamine (BBM), a natural bisbenzylisoquinoline alkaloid with manifold biological activities and pharmacological effects on lipid, cholesterol and glucose metabolism in a rat model of NAFLD, and to explicate the potential mechanisms underlying its activity. BBM administration alleviated the increase in the body weight and liver index of HFD rats. The aberrations in liver function, serum parameters, and microscopic changes in the liver structure of HFD fed rats were significantly improved upon BBM administration. BBM also significantly attenuated oxidative damage and inhibited triglyceride and cholesterol synthesis. The SIRT1 deacetylase activity was also enhanced by BBM through liver kinase B1 and activated AMP-activated protein kinase. Activation of the SIRT1/LKB1/AMPK pathway prevented the downstream target ACC (acetyl-CoA carboxylase) and elevation in the expression of FAS (fatty acid synthase) and SCD1 (steroyl CoA desaturase). BBM also modulated the expression of PPARs maintaining the fatty acid homeostasis regulation. The assessment of berbamine induced ultrastructural changes by TEM analysis and the expression of autophagic markers LC3a/b, Beclin 1 and p62 revealed the induction of autophagy to alleviate fatty liver conditions. These results show novel findings that BBM induced protection against hepatic lipid metabolic disorders is achieved by regulating the SIRT1/LKB1/AMPK pathway, and thus it emerges as an effective phyoconstituent for the management of NAFLD.

Effect of Curculigo pilosa supplemented diet on blood sugar, lipid metabolism, hepatic oxidative stress and carbohydrate metabolism enzymes in streptozotocin-induced diabetic rats. J Diabetes Metab Disord 2020; 19:1173-1184. [PMID: 33520833 PMCID: PMC7843773 DOI: 10.1007/s40200-020-00618-w] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/18/2020] [Accepted: 08/20/2020] [Indexed: 12/30/2022]
Abstract
BACKGROUND Diabetes mellitus (DM) has continued to raise concern globally and Curculigo pilosa (CP) is used for its treatment and management in folkloric medicine. In this study, the in vitro antioxidant abilities of CP and the effects of CP-supplemented diets on blood sugar, lipid metabolism, oxidative stress and key carbohydrate metabolizing enzymes in streptozotocin (STZ)-induced diabetic rats were investigated. METHODS Polyphenol contents (total phenolic and total flavonoid) and antioxidant ability of different extracts of CP were determined in vitro. Diabetes mellitus were stimulated in healthy rats by single intraperitoneal administration of 50 mg/kg streptozotocin and it was confirmed by elevated blood glucose level after 3 days. Thirty six rats were distributed into six groups of six rats each and diabetic rats were fed with 5 and 10% CP-supplemented diet for 21 days. Thereafter, the effects of the dietary regimen were evaluated on blood glucose, body weight, hepatic carbohydrate metabolizing enzymes, lipid profile, oxidative stress markers, serum markers of hepatic and renal damages and histopathology studies. RESULTS Different extracts of CP contained polyphenol contents and exhibited antioxidant properties in different models used. Diabetic rats showed elevated level of blood glucose and body weight loss. Treatment of diabetic rats with CP-supplemented diet significantly (p < 0.05) lowered the blood glucose and improved body weight loss. Also, the treatment with the CP-supplemented diet significantly (p < 0.05) enhanced the activities of hepatic glycolytic (hexokinase and glucose-6-dehydrogenase) and lowered the gluconeogenic (fructose 1, 6 biphosphatase and glucose-6-phosphatase) enzymes in diabetic rats. The lipid profile, oxidative stress markers and serum markers of hepatic and renal damages were significantly (p < 0.05) restored to near normalcy in the diabetic rats. Histopathological slides also showed improvements in pancreas and hepatic tissues of diabetic rats treated with CP-supplemented diet. CONCLUSION Data obtained in this study suggested that CP-supplemented diet could be used as dietary regimen in the management of DM.

[PMID: 32249934 DOI: 10.1111/1750-3841.15109] [Citation(s) in RCA: 22] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/17/2019] [Revised: 01/13/2020] [Accepted: 02/11/2020] [Indexed: 02/06/2023]
Abstract
We aimed to investigate) the effects of Aronia melanocarpa berry extract (AMBE) on hepatic insulin resistance and its mechanism at the molecular level in high-fat diet (HFD)- and streptozotocin (STZ)-induced type 2 diabetes mellitus (T2DM) rats. The rats were supplemented with AMBE at doses of 100 and 400 mg/kg body weight (bw) daily for 8 weeks. AMBE significantly reduced blood glucose and serum insulin levels and the homeostatic model assessment for insulin resistance score; improved glucose tolerance; increased hepatic glycogen content; and regulated glucose metabolism enzyme activity, including glucokinase, pyruvate kinase, phosphoenolpyruvate carboxykinase, and glucose-6-phosphatase in the liver. AMBE also reduced lipid accumulation and oxidative stress along with inflammation in the hepatic tissue of T2DM rats and improved hepatic function. The phosphoinositide 3-kinase (PI3K)/protein kinase B (Akt) signaling pathway was activated by AMBE through the elevation of insulin receptor substrate-2, PI3K, Akt, and glycogen synthase kinase-3β phosphorylation and glucose transporter 2, which might contribute to the promotion of glycogen synthesis and improvement of hepatic insulin resistance. AMBE shows promise as an ingredient of functional foods for alleviating hepatic insulin resistance in T2DM. PRACTICAL APPLICATION: The extract from the berries of Aronia melanocarpa (Michx.) Elliott (AMBE), with its relatively high content of polyphenolic compounds, has been shown to exert hypoglycemic effects in animal models of diabetes. Our findings support the use of A. melanocarpa as a functional food additive for the alleviation of hepatic insulin resistance and the management of glucose homeostasis in T2DM.

Abstract
Alcoholic liver disease (ALD) has become one of the leading causes of death in the world. Berbamine (BM), a natural product mainly derived from Berberis vulgaris L, possesses multiple bioactivities as a traditional medicine. However, the protective effect of BM on ALD remains unknown. In this study, we investigated the effect of BM on ethanol-induced hepatic injury in mice and its underlying mechanism. It was shown that BM at 0.3125-40 μmol·L-1had no effect on macrophages and hepatocytes proliferation. BM at 5-20 μmol·L-1 significantly inhibited lipopolysaccharide (LPS) or acetate-induced IL-1β and IL-6 mRNA expression in RAW264.7 cells. Moreover, BM treatment significantly inhibited LPS-induced p65 and STAT3 phosphorylation in RAW264.7 cells. Hepatic histopathology analysis showed that inflammatory cells infiltration and lipid accumulation were suppressed by 25 and 50 mg·kg-1 BM administration in ethanol-induced hepatic injury mouse model. Meanwhile, BM treatment significantly inhibited serum ALT and AST levels in ethanol-fed mice. Oil red O staining results showed that BM administration ameliorated hepatic lipid accumulation in ethanol-fed mice. Preventions of ethanol-induced hepatic injury by BM were reflected by markedly decreased serum and hepatic triglyceride (TG) and total cholesterol (TC) contents. Real-time PCR results showed that BM treatment significantly inhibited pro-inflammatory cytokines mRNA expression in ethanol-fed mouse liver. Remarkably, the mechanism of action of BM was related to the reduction of ethanol-induced NF-κB and STAT3 phosphorylation levels in liver. In addition, BM treatment significantly inhibited ERK phosphorylation but not JNK and p38 of MAPK pathway. Taken together, our results demonstrate a beneficial effect of BM on ethanol-induced liver injury via a mechanism associated with inactivation of NF-κB, STAT3 and ERK pathway, which gives insight into the further evaluation of the therapeutic potential of BM for ALD.

Abstract
The incidences of diabetic mellitus and other metabolic diseases such as hypertension and hyperlipidemia are increasing worldwide; however, the current treatment is not able to control the rapidly increasing trend in diabetes mortality and morbidity. Studies related to the effectiveness of extracts and pure compounds obtained from plants have shown promising responses in preclinical and clinical studies related to these metabolic diseases. Plants belonging to the genus Berberis (Family: Berberidaceae) are widely distributed with nearly 550 species worldwide. Extracts and compounds obtained from Berberis species, especially Berberine alkaloid, showed effectiveness in the management of diabetes and other metabolic diseases. Various pharmacological experiments have been performed to evaluate the effects of Berberis extracts, berberine, and its natural and chemically synthesized derivatives against various cell and animal disease models with promising results. Various clinical trials conducted so far also showed preventive effects of Berberis extracts and berberine against metabolic diseases. The present review focuses on i) research updates on traditional uses, ii) phytopharmacology and clinical studies on Berberis species, and iii) active metabolites in the prevention and treatment of diabetes and other metabolic diseases with a detailed mechanism of action. Furthermore, the review critically analyzes current research gaps in the therapeutic use of Berberis species and berberine and provides future recommendations.

Some molecular structural features of glycogen in the kidneys of diabetic rats. Carbohydr Polym 2019; 229:115526.

Abstract
Glycogen, a highly-branched glucose polymer, functions as a sugar reservoir in many organs and tissues. Liver glycogen comprises small β particles which can bind to form into large agglomerates (α particles) which readily degrade to β particles in diabetic livers. Muscle glycogen has only β particles, optimal for quick energy release. Healthy kidney contains negligible glycogen, but there is an abnormally high accumulation in diabetic kidneys. We here compare the molecular structure of glycogen in diabetic kidneys with that in liver and muscle, using a diabetic rat model. This involved exploring extraction techniques to minimize glycogen degradation. Using size exclusion chromatography and transmission electron microscopy, it was found that there were only β particles in diabetic kidneys. These are postulated to form during periods of abnormally high blood sugar, the driving force being the need to reduce blood sugar under such circumstances.

Abstract
Diabetes mellitus, especially type 2 diabetes mellitus (T2DM), has become a significant public health burden. Rhizoma coptidis (RC), known as Huang Lian, is widely used for treating diabetes in China. The bioactive compounds of RC, especially alkaloids, have the potential to suppress T2DM-induced lesions, including diabetic vascular dysfunction, diabetic heart disease, diabetic hyperlipidemia, diabetic nephropathy, diabetic encephalopathy, diabetic osteopathy, diabetic enteropathy, and diabetic retinopathy. This review summarizes the effects of RC and its bioactive compounds on T2DM and T2DM complications. Less research has been conducted on non-alkaloid fractions of RC, which may exert synergistic action with alkaloids. Moreover, we summarized the pharmacokinetic properties and structure-activity relationships of RC on T2DM with reference to extant literature and showed clearly that RC has potential therapeutic effect on T2DM.

Abstract
Allyl isothiocyanate (AITC), a dietary phytochemical found in some cruciferous vegetables, is commonly used as an antimicrobial, anticancer, and antioxidant agent. In the present study, we investigated the effects of AITC on insulin resistance and transcription factors in a diabetic rat model. A total of 42 Wistar rats were divided into six groups and orally treated for 12 weeks as follows: (i) control; (ii) AITC (100 mg/kg body weight [BW]); (iii) high fat diet (HFD); (iv) HFD + AITC (100 mg/kg BW); (v) HFD + streptozotocin (STZ, 40 mg/kg BW); and (vi) HFD + STZ + AITC. Administration of AITC reduced blood glucose, total cholesterol, triglycerides, and creatinine levels, but increased (P < 0.001) total antioxidant capacity. In AITC-treated rats, the glucose transporter-2, peroxisome proliferator-activated receptor gamma, p-insulin receptor substrate-1, and nuclear factor erythroid-derived 2 in the liver and kidney were increased while nuclear factor-kappa B was downregulated (P < 0.05). In conclusion, AITC possesses antidiabetic, antioxidant, and anti-inflammatory activities in HFD/STZ-induced T2DM in rats. These findings may further justify the importance of AITC in phytomedicine.
