A new labdane diterpenoid from Scoparia dulcis improving pancreatic function against islets cell apoptotic by Bax/Bcl-2/Caspase-3 pathway. JOURNAL OF ETHNOPHARMACOLOGY 2024; 322:117571. [PMID: 38103847 DOI: 10.1016/j.jep.2023.117571] [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: 10/26/2023] [Revised: 12/01/2023] [Accepted: 12/07/2023] [Indexed: 12/19/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Scoparia dulcis has been identified as a significant ethnopharmacological substance in the Li, Zhuang, and Dai ethnic groups of China. Traditional medicine use S. dulcis to treat numerous illnesses, most notably diabetes. The considerable antidiabetic properties of this herbal remedy have been established by several clinical investigations and animal experiments. The islet is the intended target of S. dulcis, although the cause of its activity and mechanism for diabetes treatment is unclear. The diterpenoids from S. dulcis have been shown in the literature to have significant hypoglycemic efficacy and to protect islet cells in vitro. Diterpenoids may be the components of this herbal remedy that preserve islets, but further research is needed. AIM OF THE STUDY This study was projected to investigate the new diterpenoid scoparicol E from S. dulcis and examined its islet-protective effect and the potential mechanism both in vitro and in vivo. METHODS The structure of the novel diterpenoid scoparicol E was clarified by employing a wide range of spectroscopic methods. Using CCK-8 tests, cytotoxicity and antiapoptotic activity of scoparicol E were detected. Serum biochemical analysis and pathologic examination were performed to study the protective effect of scoparicol E against islet damage. The specific mechanism of action of scoparicol E was investigated through the mitochondrial membrane potential, Annexin V-FITC flow cytometry, and western blotting. RESULTS Scoparicol E reduced MLD-STZ-induced hyperglycemia in mice and increased insulin and islet apoptosis. Scoparicol E effectively suppressed the Bax/Bcl-2/Caspase-3 pathway, according to the in vivo western blot investigation. Scoparicol E showed significant antiapoptotic action in vitro. We also showed that scoparicol E might prevent islet cells from dying by inhibiting the Bax/Bcl-2/Caspase-3 pathway. The Annexin V-FITC flow cytometry results revealed that MIN6 cell apoptosis was considerably decreased following scoparicol E intervention, showing anti-islet cell apoptosis action. Furthermore, the Caspase-3-mediated apoptosis pathway depends on cytochrome c and the potential of the mitochondrial membrane. Scoparicol E prevented the release of cytochrome c, restored the mitochondrial membrane potential, and prevented MIN6 cell apoptosis. CONCLUSION We demonstrated the new diterpenoid scoparicol E could protect islet cells apoptosis by modulating the Bax/Bcl-2/Caspase-3 pathway.

Abstract
The relationship between the immune system and metabolic diseases is complex and increasingly recognized as critical to understanding conditions like obesity, diabetes, and cardiovascular diseases. Modulation of the immune system in patients with metabolic disorders can offer several potential benefits. While the salutary impact of plant-derived bioactive compounds on metabolic and immune functions is acknowledged, there is a paucity of comprehensive reviews on the multifaceted and synergistic mechanisms through which these effects are mediated. This review elucidates the therapeutic potential of phytochemical formulations in ameliorating metabolic disorders and delineates their mechanistic implications on relevant biomarkers and immune modulation. Our analysis reveals a predominance of plant species, including Boswellia serrata, Cinnamomum cassia, Citrus bergamia, Coffea arabica, Ficus racemosa, Momordica charantia, Morus Alba, and Trigonella foenum-graecum, that have undergone clinical evaluation and have been substantiated to confer both metabolic and immunological benefits. The phytoconstituents contained in these plants exert their effects through a range of mechanisms, such as improving glucose regulation, reducing inflammatory responses, and modulating immune system. As such, these findings hold considerable promise for clinical and therapeutic translation and necessitate further empirical validation through randomized controlled trials and mechanistic elucidations to affirm the safety and efficacy of herbal formulations.

Abstract
Diabetes, a chronic physiological dysfunction affecting people of different age groups and severely impairs the harmony of peoples' normal life worldwide. Despite the availability of insulin preparations and several synthetic oral antidiabetic drugs, there is a crucial need for the discovery and development of novel antidiabetic drugs because of the development of resistance and side effects of those drugs in long-term use. On the contrary, plants or herbal sources are getting popular day by day to the scientists, researchers, and pharmaceutical companies all over the world to search for potential bioactive compound(s) for the discovery and development of targeted novel antidiabetic drugs that may control diabetes with the least unwanted effects of conventional antidiabetic drugs. In this review, we have presented the prospective candidates comprised of either isolated phytochemical(s) and/or extract(s) containing bioactive phytoconstituents which have been reported in several in vitro, in vivo, and clinical studies possessing noteworthy antidiabetic potential. The mode of actions, attributed to antidiabetic activities of the reported phytochemicals and/or plant extracts have also been described to focus on the prospective phytochemicals and phytosources for further studies in the discovery and development of novel antidiabetic therapeutics.

Abstract
This review discusses the chemical constituents and pharmacological effects of Scoparia dulcis L. (S. dulcis) plants. So far, approximately 160 compounds have been identified from S. dulcis, among which 115 compounds may be related to the treatment of metabolic syndrome. Extracts of S. dulcis have effects of reducing fasting blood glucose level, increasing the plasma insulin level, and stimulating insulin secretion to treat diabetes. They also produce antihyperlipidemic effects by increasing serum high-density lipoprotein levels, the anti-atherogenic index of plasma, and HMG-CoA reductase activity. The chemical composition of glutinol and glutinone, isolated from S. dulcis, provide potential anti-inflammatory effects. These compounds can also reduce total cholesterol, triacylglycerol, and low-density lipoprotein (LDL)-cholesterol and increase high-density lipoprotein (HDL)-cholesterol to provide the anti-atherosclerotic effect. S. dulcis exerts anti-arthritic properties through its effect on cytokine levels, significantly reducing IFN-γ and IL-6 levels and elevating IL-10 levels. The extracts carry out hepatoprotective effect by preventing the descent of the antioxidative enzymes of superoxide dismutase (SOD), glutathione peroxidase (GPx), glutathione reductase (GRd), and glutathione-S-transferase (GST). Therefore, S. dulcis provides new potential for medicine given its numerous therapeutic properties and can be promoted as a complementary or alternative therapy for patients with chronic conditions. This review discusses the chemical constituents and pharmacological effects of S. dulcis plants. S. dulcis provides new potential for medicine and can be promoted as a complementary or alternative therapy for patients with chronic conditions.![]()

Abstract
OBJECTIVE The prevalence of complementary and alternative medicine (CAM) usage among patients with type 2 diabetes mellitus (T2DM) in Indonesia is high. However, to date, little is known about why Indonesian T2DM patients choose CAM therapies, how their knowledge, attitude and practice (KAP) of CAM affects their choices, or how demographics correlate with patient choices. Therefore, this study aimed to investigate the KAP and predictors of CAM usage in T2DM patients in Indonesia. METHODS This was an observational, cross-sectional study. Patients were interviewed using a questionnaire. Chi-square tests or Fisher's exact tests were used to compare demographic and clinical data, as well as KAP assessments, between T2DM patients who use and do not use CAM. Multivariate logistic regression analyses were used to investigate predictors of CAM usage. RESULTS A total of 628 T2DM patients were enrolled in the study. CAM therapies were used by 341 patients (54.3%). The most common therapies were herbs and spiritual healing, used by 100.0% and 68.3% of CAM-using patients, respectively. CAM therapies were frequently recommended by family members (91.5%), and CAM users had significantly more knowledge and more positive attitudes toward CAM therapies than nonusers. Among users, 66% said they would not follow their healthcare providers' instructions to not use CAM therapies, and 69.5% said they would not disclose their plan to use CAM therapies with their healthcare provider. Neither demographic nor clinical characteristics were associated with CAM use. The factors that best predicted the use of CAM therapies were their availability and low cost (odds ratio [OR] = 4.59; 95% confidence interval [CI]: 3.01-7.01), the belief that CAM therapies were safe (OR = 2.04; 95% CI: 1.40-2.95), the belief that CAM therapies could help with diabetes control (OR = 1.75; 95% CI: 1.15-2.66), and the belief that CAM therapies could help maintain physical health (OR = 1.68; 95% CI: 1.13-2.49). CONCLUSION CAM therapy users were more knowledgeable and had more positive attitudes toward CAM, but most of them chose not to disclose their CAM use to their healthcare providers. CAM use in Indonesia was associated with its accessibility, affordability, safety and effectivity, but not with any demographic or clinical characteristics. This study provided new evidence and insights for nurses and physicians in Indonesia that will help to design educational programs about the safety and efficacy of CAM therapies.

Abstract
At present, the pathologic spectrum of obesity-insulin resistance (IR)-diabetes mellitus (DM) represents not only a pressing matter in public health but also a paramount object of study in biomedical research, as they constitute major risk factors for cardiovascular disease (CVD), and other chronic non-communicable diseases (NCD). Phytotherapy, the use of medicinal herbs (MH) with treatment purposes, offers a wide array of opportunities for innovation in the management of these disorders; mainly as pharmacological research on small molecules accumulates. Several MH has displayed varied mechanisms of action relevant to the pathogenesis of obesity, IR and DM, including immunological and endocrine modulation, reduction of inflammation and oxidative stress (OS), regulation of appetite, thermogenesis and energy homeostasis, sensitisation to insulin function and potentiation of insulin release, among many others. However, the clinical correlates of these molecular phenomena remain relatively uncertain, with only a handful of MH boasting convincing clinical evidence in this regard. This review comprises an exploration of currently available preclinical and clinical research on the role of MH in the management of obesity, IR, and DM.

Abstract
Background: Scoparia dulcis Linn. is reported to be used by women of Assam and Arunachal Pradesh in northeast India for treating menstrual disorders. Scoparia dulcis contains compounds that bind with estrogen receptors (ERα and ERβ) evidenced by increased PCNA in endometrial epithelium. Methods: Crude extract was orally administered at the dose of 500 mg/kg body weight/day to the female mice (60–70 days old) in five different groups. Each group containing six females included: (I) cyclic control, (II) cyclic extract treated, (III) Ovariectomized (OVX)-vehicle treated (Control), (IV) OVX-E2 treated (V) OVX- extract treated. Extract was administered for eight days to the cyclic groups and three days to the OVX groups. PCNA was detected immunohistochemically in uterine tissues and signals were analyzed by Image J software (NIH, USA). Compounds were separated by GC-MS and identified using NIST. In silico molecular docking studies was performed with human estrogen receptors (ERα and ERβ). Molecular dynamics (MD) simulations of the best interacting compound was done using gromacs. Results: The results showed cell proliferation in the uterine endometrium evidenced by PCNA. Two phytocompounds, Octadecanoic acid and methyl stearate showed binding affinity with ERα and ERβ. Conclusion: Scoparia dulcis contains compounds having binding affinity with ERα and ERβ. The present study is the first report on compounds from Scoparia dulcis showing binding affinity with human estrogen receptors which may have biological effect on female reproduction.

Abstract
OBJECTIVE Given the association between diabetes suppression and inhibition of diet-induced elevation in glucose and insulin, we investigated the effects of adding glucomannan to rice gruel on pre- and postprandial glucose and insulin concentrations. METHODS A total of 25 Japanese subjects without a history of diabetes or gastrointestinal disease (all males; aged 37-60 years; body mass index 20.4-31.6) participated in this study. Subjects received a 75-g oral glucose tolerance test (75gOGTT) and rice gruel containing 0, 0.4, or 0.8% of glucomannan. Blood samples were then obtained at preload and at 30, 60, and 120 min after receiving 75 g of glucose or rice gruel with or without glucomannan. RESULTS After the 75gOGTT, 8 subjects had normal glucose tolerance (NGT), whereas 17 showed a borderline pattern. Moreover, our data showed that greater amounts of glucomannan promoted lesser 30-min postload plasma glucose and insulin levels, with differences being larger in the borderline group than in the NGT group. CONCLUSIONS Glucomannan dose-dependently inhibited the rice gruel-induced increase in 30-min postprandial plasma glucose and insulin levels. Furthermore, greater inhibitory effects on glucose and insulin elevation were observed in the borderline group than in the NGT group.

Abstract
Herbal medicine, phytomedicine or botanical medicine are synonymous, utilizes plants intended for medicinal purposes. Medicinal use of herbal medicine in the treatment and prevention of diseases including diabetes has a long history compared to conventional medicine. Diabetes is one of the major public health concerns over the world. Diabetes or hyperglycemia is considered to be one of the common public health hazard; optimal control of which is still not possible. Persistent hyperglycemia or uncontrolled diabetes has the potential to cause serious complications such as kidney disease, vision loss, cardiovascular disease, and lower-limb amputations which contributed towards morbidity and mortality in diabetes. There are various approaches to treat and prevent diabetes as well as its secondary complications, one of it is herbal medicines. However, the selection of herbs might depends on several factors, which include the stage of progression of diabetes, types of comorbidities that the patients are having, availability, affordability as well as the safety profile of the herbs. This review focuses on the herbal and natural remedies that play the role in the treatment or prevention of this morbid disorder - diabetes, including their underlying mechanisms for the blood glucose-lowering property and the herbal products already been marketed for the remedial action of diabetes.

Elucidation of terpenoid metabolism in Scoparia dulcis by RNA-seq analysis. Sci Rep 2017; 7:43311. [PMID: 28266568 PMCID: PMC5339715 DOI: 10.1038/srep43311] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/16/2016] [Accepted: 01/25/2017] [Indexed: 11/08/2022] Open
Abstract
Scoparia dulcis biosynthesize bioactive diterpenes, such as scopadulcic acid B (SDB), which are known for their unique molecular skeleton. Although the biosynthesis of bioactive diterpenes is catalyzed by a sequence of class II and class I diterpene synthases (diTPSs), the mechanisms underlying this process are yet to be fully identified. To elucidate these biosynthetic machinery, we performed a high-throughput RNA-seq analysis, and de novo assembly of clean reads revealed 46,332 unique transcripts and 40,503 two unigenes. We found diTPSs genes including a putative syn-copalyl diphosphate synthase (SdCPS2) and two kaurene synthase-like (SdKSLs) genes. Besides them, total 79 full-length of cytochrome P450 (CYP450) genes were also discovered. The expression analyses showed selected CYP450s associated with their expression pattern of SdCPS2 and SdKSL1, suggesting that CYP450 candidates involved diterpene modification. SdCPS2 represents the first predicted gene to produce syn-copalyl diphosphate in dicots. In addition, SdKSL1 potentially contributes to the SDB biosynthetic pathway. Therefore, these identified genes associated with diterpene biosynthesis lead to the development of genetic engineering focus on diterpene metabolism in S. dulcis.

Sensitive quantification of coixol, a potent insulin secretagogue, in Scoparia dulcis extract using high-performance liquid chromatography combined with tandem mass spectrometry and UV detection. Biomed Chromatogr 2017; 31. [PMID: 28214376 DOI: 10.1002/bmc.3964] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/01/2016] [Revised: 12/23/2016] [Accepted: 02/15/2017] [Indexed: 11/10/2022]
Abstract
Diabetes is a major global health problem which requires new studies for its prevention and control. Scoparia dulcis, a herbal product, is widely used for treatment of diabetes. Recent studies demonstrate coixol as a potent and nontoxic insulin secretagog from S. dulcis. This study focuses on developing two quantitative methods of coixol in S. dulcis methanol-based extracts. Quantification of coixol was performed using high-performance liquid chromatography-tandem mass spectrometry (method 1) and high-performance liquid chromatography-ultraviolet detection (method 2) with limits of detection of 0.26 and 11.6 pg/μL, respectively, and limits of quantification of 0.78 and 35.5 pg/μL, respectively. S. dulcis is rich in coixol content with values of 255.5 ± 2.1 mg/kg (method 1) and 220.4 ± 2.9 mg/kg (method 2). Excellent linearity with determination coefficients >0.999 was achieved for calibration curves from 10 to 7500 ng/mL (method 1) and from 175 to 7500 ng/mL (method 2). Good accuracy (bias < -8.6%) and precision (RSD < 8.5%) were obtained for both methods. Thus, they can be employed to analyze coixol in plant extracts and herbal formulations.

Dietary Habits of Type 2 Diabetes Patients: Variety and Frequency of Food Intake. J Nutr Metab 2017; 2016:7987395. [PMID: 28127469 PMCID: PMC5227304 DOI: 10.1155/2016/7987395] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/04/2016] [Accepted: 11/29/2016] [Indexed: 11/24/2022] Open
Abstract
The objective of the present study was to observe the dietary patterns and food frequencies of type 2 diabetes patients attending the clinics of the Family Practice Center of the University of Sri Jayewardenepura, located in a highly urbanized area in Sri Lanka. An interviewer administered questionnaire based cross-sectional study was conducted among randomly selected 100 type 2 diabetes patients [age 35–70 years; mean age 55 ± 9 (males = 44; females = 56)]. The data were analyzed by SPSS version 18.0 software. Vegetables, fatty foods, and poultry consumption were in accordance with the national guidelines. A significant percentage (45.5%) consumed rice mixed meals for all three meals and only 67% consumed fruits at least once a day. Majority (71%) consumed full-cream milk and sugar intake (77%) was in accordance with the guidelines. Noncaloric sweetener usage was nonexistent. Daily green leafy vegetable intake and the quantity consumed were inadequate to obtain beneficial effects. From the study population, 44% [females 50%; males 36%] of the patients were either overweight or obese. However, only 60% of those patients accepted that they were either overweight or obese. Only 14% exercised daily while 69% never exercised. Study revealed the importance of educating patients with type 2 diabetes on dietary changes and more importantly the involvement in regular physical exercises.
