(en)FIELD OF INVENTION
The present invention relates to a plant based formulation for the prevention and management of obesity and associated complications like hypertension, insulin resistance, dyslipidemia and coronary heart disease. The formulation is beneficial in managing particularly adipokines i.e. leptin, adiponectin including ghrelin and resistin.
BACKGROUND OF THE INVENTION
Over weight and obesity poses a major public health challenge. Obesity is a chronic condition that develops as a result of an interaction between a person's genetic make up that are not well understood. However, social, behavioral, cultural, psychological, metabolic factors are also contributing to obesity. Obesity is the major health care challenge for the 21 st century, and its prevalence is increasing globally (WHO 1997, Popkin B M et al 1997). The prevalence of obesity and overweight is influenced by a complex interaction of genetic, environmental and behavioral factors. Obesity occurs when caloric intake exceeds than energy expenditure, but a growing body of evidence supports the view that obesity is caused by inherited tendencies to subtle disorders of the weight regulating mechanism magnified by a poor diet and lack of activity practiced by most of the population. (Mokdad. A. et al., 2004, N.I.H., 2004). Unfortunately, there has been a phenomenal increase in the prevalence of obesity in India, particularly in the urban area. Obesity is risk factor for a wide range of disease and is associated with increased morbidity and reduced life expectancy. Several studies reported childhood and adolescence obesity is associated with pre-matured death in adulthood (Rosengren A et al 1999, Yarnell J W et al 2000, Engeland A 2003). Epidemiologic studies have shown a strong correlation between socio-economic status and prevalence of obesity. This relationship is stronger in women (Calle E E et al 1999, Bender R et al 1999).
Overweight and obesity have reached epidemic proportion in U.S.A, increasing among all age, race and ethnic groups and in both men and women. The most recent survey from National Health Examination Survey (NHANES) for 1999 to 2000 reported the age-adjusted prevalence of overweight [defined as BMI: 25 kg/m 2 ] as 64.5% and obesity [defined as BMI: 30 kg/m 2 ] as 30.5° A for U.S. adults (Flagal, K. M. et al., 2002). The prevalence of obesity and overweight continues to increase dramatically, in past, as an intended consequence of the economic, social and technological advances that have contributed to unhealthy dietary habits and sedentary behavior during the past several decades. It is the second leading cause of preventable death in the U.S. today accounting for ˜300,000 deaths per year (Allison, D. B et al; 1999).
Recently, it is reported that the prevalence of obesity is markedly increased i.e. 19.3 percent in 2001 to 22.7 percent in 2007. Similarly there is continuous increase in the prevalence of diabetes and obesity causing serious medical complications. As obesity is a significant risk factor for development of diabetes therefore a drastic preventive measures are required for the obesity to prevent future development of insulin resistance. A socio-cultural factor is associated with prevalence of obesity and diabetes. Very recently Allison L. et al (2010) reported that high prevalence is associated with lower income and comparatively least educated group of people.
Several evidences indicate that obesity is associated with an increased risk of cardiovascular disease, type-II diabetes mellitus, hypertension, stroke and dyslipidemia (Huang Z et al 1997, Shoff S M et al 1998). Joint national committee on prevention, evaluation and treatment of high blood pressure (1997), defined obesity as the major risk factor for CVD and associated mortality. Numerous studies showed that the pattern of body fat distribution affects morbidity and mortality from cardiovascular disease (Bouchard C et al 1990, Lapidus L et al 1984). Many studies have demonstrated the beneficial effect of weight reduction on cardiovascular risk factors such as hypertension and dyslipidemia (Scherrer V et al 1991, De Simone A et al 1992, Rossner S et al 1987).
Overweight and obese people have an increased incidence of cardiovascular disease (CVD), including heart attack, congestive heart failure, sudden cardiac death, angina and abnormal heart rhythm (office of the U.S. Surgeon General, 2004).
Excess fat and weight is combined with adverse metabolic changes associated with chronic degenerative diseases that increase both morbidity and mortality. Obesity has a negative effect on lipid levels in the blood, which often leads to the development of a condition known as dyslipidemia. Dyslipidemia, a primary risk factor for coronary artery disease, occurs when LDL cholesterol and triglyceride levels are high, HDL cholesterol is low or any combination of these factors. People with an excessive amount of body fat have higher levels of TG and LDL and lower level of HDL cholesterol in the blood which may cause inflammation and an increased risk of developing CVD. (N.I.H., 2004). Physicians often attribute this abnormal shift in lipid levels to weight gain. Losing weight conversely has an opposite effect.
A high level of cholesterol in blood is associated with an increased risk of heart attack because cholesterol is major component of the plaques deposited in arterial walls. Cholesterol, like oil, cannot dissolve in blood unless it is combined with special proteins called lipoproteins. The cholesterol combined with LDL is “bad” cholesterol that deposits cholesterol is associated with an increased risk of heart attack (Archives of Internal Medicine, 2000).
High blood pressure is a risk factor for developing atherosclerosis and heart attack. Both high systolic pressure and high diastolic pressure increase the risk of heart attack.
More than 80% people with the most common form of type-2 diabetes are obese or overweight. Data from CDC's National Health and Nutrition Examination Survey III shows that ⅔ rd of adult men and women in the U.S. diagnosed with type 2 diabetes have a BMI of 27 or greater, which is classified as overweight and unhealthy (Archives of Internal Medicine, 2000).
As obesity alters the body's ability to control blood sugar using insulin, there is an increased risk of developing diabetes. The body begins over producing insulin to regulate blood sugar levels but over time the body can no longer keep these levels in a normal range. Eventually this inability to achieve balance results in higher, unhealthy blood sugar levels, ultimately leads to the development of type 2 diabetes (North American Association for study of obesity, 2004). Obesity complicates the management of type 2 diabetes by increased insulin resistance and glucose intolerance, which makes drug treatment for the disease less effective (American Obesity Association, 2004).
Hs C-reactive protein (CRP) is correlated with pre-abdominal obesity and a raised level predicts the risk of developing type-II diabetes (Freeman D J et al 2002, Barzilay J I et al 2001, Pradhan A D et al 2001). Obesity mediated cytokine production is another important central mechanism for systemic elevation of CRP and IL-6. A strong correlation with markers of endothelial activation and dysfunction is reported (Yudkin J S et al 2000). It is reported that IL-6 and CRP levels are responsible for adipocyte activation. Other potential mediators of insulin resistance deriving from adipose store is TNF a (Hotamisligil G S et al 1995, 1996), leptin (McNeely M J et al 1999), free fatty acid (Groop L C et al 1991) and resistin (Steppan C M et al 2001). The identification of obese and non-obese individuals and risk for the development of diabetes the measurement of above biomarkers are significantly useful.
TNF-α decreases tyrosine kinase activity of the insulin receptor and is overproduced in adipose tissues in insulin-resistant rodents and humans suggesting that it is a possible mediator of insulin resistance in obesity and diabetes (Hotamisligil G S et al 1993, 1994, 1994a).
Obesity results in marked alterations in cardiac functions due to increased fatty acids uptake and oxidation. Obesity also causes release of adipokines, such as leptin and adiponectine which have shown significant impact in the regulation of cardiac functions. There is association between obesity, cardiovascular disease, lipid metabolism and adipokines. Human obesity is characterized by elevated plasma leptin levels and resistance to the metabolic effects of the hormone to the extent that high plasma leptin levels are ineffective in reducing fat accumulation (Narkiewicz K et al 1999). In humans, there is evidence of leptin resistance and leptin concentration increases with obesity and correlates strongly with percentage body fat in both sexes (Mohamed Ail et al 1998). Similarly, one of the epidemiological studies of 2537 men and women showed a strong association between fasting insulin level, leptin concentration and obesity (Zimmet P Z et al 1998). Further, higher leptin levels are also associated with the development of obesity and type-II diabetes mellitus (Chessler S D et al 1998, McNeely M J et al 1999).
Obesity related disorders including metabolic syndrome, diabetes, atherosclerosis, hypertension and coronary artery disease are associated with decreased plasma levels of adiponectin, insulin resistance and endothelial dysfunction (Han S H et al 2007). Its levels are low in obesity and increases after weight loss (Arita Y et al 1999, Weyer C et al 2002, Yang W S et al 2001).
Treatment of obesity should be based on its severity. Despite the magnitude of the problem of obesity, most health care provides uncomfortable dealing with it. This has led to publication of a set of guidelines on the treatment of obesity by N.I.H. urging health care provides to address obesity in the office setting (Aronne L J 2002).
Sibutramin and Orlistat both the drug are approved for obesity management by the FDA (Rolls B J et al 1998, Hill J O et al 1999), but its long term application are not safe and causes mood enhancement and cardiovascular excitation (Graddoc K D 1978, Abenhain L et al 1996, Bowen R et al 1997). Recent data suggested that the statin therapy based on CRP values would result in fewer events and regression of atherosclerosis. Elevation of CRP is related to obesity, diabetes, estrogen therapy, hypertension smoking etc.
The classical literature of Ayurveda has given a comprehensive description about the etiopathogenesis and management of obesity (ati-sthula or medo-roga) (Ashtau-ninditiyādhyaya, Charak sutra 21:4-10). Charak has described the genetic (Sahaj) and environmental factors responsible for excessive deposition of meda-dhātu. The genetic pre-disposition is one of the most important factors of obesity.
Recently maximum time and attention has been paid towards the utilization of plant based formulations useful in the prevention and management of various clinical conditions as these agents have shown better efficacy over standard conventional pharmacologic therapies and found to be more safer side as such drugs have no adverse effects on various body system. Thus based on ancient medical literature lead was taken and a novel plant based formulation was evaluated following multi-targeted anti-obesity activity among obese/over weight patients.

Hypothesis
Recently it has been reported that obesity and insulin resistance is mainly characterized by high leptin and low adiponectin concentrations and is the basic markers for onset of obesity. Hypoadiponectinemia contribute to a low grade systemic chronic inflammatory state whereas insulin resistance is also significantly associated with increasing body weight and is a major risk factor for future onset of diabetes mellitus among obese patients. The effect of adiponectin diminution is also responsible for glucose intolerance as well as abnormal lipid metabolism. Therefore the present test formulation contains the extracts of Salacia reticulata, Garcinia indica, Dioscorea bulbifera, Terminalia chebula in effective doses as all these four plants have shown weight reducing, anti-inflammatory, anti-hyperlipidemic and insulin sensitivity enhancing activity. The test formulation has capability to reduce leptin level and enhances the adiponectin concentration as proven through experimental and clinical trials. In view of the above facts it is proposed that present test formulation has potential role in the prevention and management of major coronary risk factors particularly obesity thus it can prevent the future adverse cardiac event among the obese individuals. Further by control of body weight the complication like hypertension, osteoporosis, neurodegenerative disorders etc. can also be prevented. Thus it is proposed that since the obesity is a multi-factorial disorder and highly contributing in the development of coronary heart disease/ischemic heart disease and is the major cause for morbidity and mortality due to over weight and high BMI, the present test formulation contained the extract of four medicinal plants i.e. Salacia reticulata, Garcinia indica, Dioscorea bulbifera, Terminalia chebula . The plant Salacia reticulata , contains the active compound salacinol and kotalanol which has shown strong action on glucose metabolism and improves insulin sensitivity. It is a potent anti-obesity drug proven in several studies. Garcinia indica has been proven for its anti-oxidant, anti-inflammatory, lipase inhibitor (anti-obesity) as well as neuroprotective actions. Dioscorea bulbifera is the plant which has shown anti-hypercholesterolemic and triglycerides reducing activity and beneficial in the prevention and management of conventional coronary risk factors. The pharmacological action of Terminalia chebula is reported as blood glucose lowering, immunomodulatory, nephro-protective properties. In the light of these pharmacological therapeutic activity of plant candidates included in the present test formulation the present invention is of clinical significance for the management of obesity and obesity associated complications.
About and Plant
1 . Salacia reticulata (Saptachakra)
Salacia reticulata: Salacia reticulata belongs to Hippocrateaceae family. It is mainly distributed in Southern India. It is a large genus of climbing or creeping shrub or rarely small tree. Root and stem of Salacia reticulata are used for the treatment of diabetes mellitus in Ayurveda and Siddha System of Medicine. Salacinol, Kotalanol and kotalagenin 16-acetate showed a stronger inhibition of the increased serum glucose levels in maltose and sucrose loaded rats than acarbose (Matsuda et al 1999; Matsuda et al 2002). Salacia reticulata strongly inhibited the activities of α-glucosidase and α-amyalse, but not that of 3-glucosidase. (Shimoda et al 1998). In Siddha System of Medicine, Salacia reticulata has been used for the treatment of Diabetes mellitus. It is also useful in the treatment of inflammations, wounds, ulcers, liver diseases etc.
2 . Garcinia indica (Kokum):
Belongs to the family Clusiaceae. Seeds and fruits of Garcinia indica is used for medicines and cosmetics. Hydroxycitric acid (HCA) is extracted from the rind of the fruit is used as hypocholesterolemic agent. It is also a potential anti-obesity agent. The anti-oxidant property of aqueous extract of the plant is observed. Garcinia indica extract is having anti-allergic effects. It contains oxalicacid, malic acid, polyphenols, carbohydrates, anthocyanin and ascorbic acid. Anti-oxidant property (Mishra A et al 2006) is due to Garcinol. Isogarcinol have shown anti-inflammatory activity, lipase inhibitor (anti-obesity) (Jena B S et al 2002) and neuroprotective effect.
Aqueous and ethanolic extract of Garcinia indica fruit-rind has shown ulcer protective activity against indomethacin induced ulcerogenesis and HCl/ethanol induced gastric lesion (Amol Bhalchandra Deose et al 2011). Water extract of Garcinia indica has shown anti-microbial properties against certain microbes and cytotoxic properties on Balb/C3T3 mouse fibroblasts (KN Varalakshmi et al 2010). In an experimental study on Wistar albino rats Garcinia indica Linn. Fruit rind aqueous and ethanolic extract has shown anti-oxidant and hepatoprotective effect (Amol Bhalchandra Deore et al 2011). Garcinol a polyisoprenglated benzophenane derivative has a potent anti-oxidant and a glycation inhibitor under specified conditions (Fumio yamaguchi et al 2000).
Garcinia indica fruit extract prevents cyclophosphamide induced oxidative stress in rat's brain by reducing power and free scavenging ability and higher phenol content (Tushrendra Singh et al 2011). In a Randomized clinical trials (RCTs) suggest that Garcinia indica extracts/HCA can cause short term weight loss the magnitude of the effect is small (Ighoonakpoya et al 2011). Treatment with Garcinia indica fruit extract could prevent cyclophosphamide induced oxidative stress in brain and it is a better protectant (Tushrendra Singh et al 2011).
3. Dioscorea bulbifera (Varahikand)
It is a member of the Dioscoraceae family. Tubers of Dioscorea have been used as a food and herbal medicine. The pharmacologically active components of Dioscorea species is diosgenin, which is a steroidal saponin and dioscin, a form of diosgenin with sugar attached. Recent studies suggest that dietary diosgenin may lower plasma cholesterol levels, reduce blood sugar and decrease inflammation.
In numerous studies, plant steroids have shown to lower plasma cholesterol levels in animal models. Dietary diosgenin has shown decrease in plasma cholesterol levels through reduced cholesterol absorption by the liver (Sauvaire Y et al 1991). Dubey G P et al (2008) studied the beneficial role of test formulation containing extract of Dioscorea bulbifera in the management of various CHD risk factors involved with menopausal women.
Chemical Constituents:
Albuminoides, Fats, Carbohydrates, Furanoid norditerpenes—Diosbulbins A,B,C,D,E,F,G,H; Dihydrophenenthrene, tetrahydrophenenthrene, D-Sorbitol, A dihydrophenenthrene, 2,4,6,7-tetrahydroxy, 9,10 dihydroxyphenenthrene, phytoestrogen.
Diosgenin, a steroid sapogenin, is the product of hydrolysis by acids, strong bases, or enzymes of saponins, extracted from the tubers of Dioscorea wild yam, such as the Kokoro. The sugar-free (aglycone), diosgenin is used for the commercial synthesis of cortisone, pregnenolone, progesterone, and other steroid products and has shown anti-obesity, anti-inflammatory and hypolipidemic activity.
4 . Terminalia chebula (Harilaki):
It belongs to family combrataceae and found all over India. Fruit and seed part is used for medicinal purpose which contains tannin, chebulic acid, chebulinic acid, ellagic acid, gallic acid and resin and used mainly for heart diseases. Studies have reported that Terminalia chebula protect the cells against free radical scavenging activities Terminalia chebula has shown anti-inflammatory, immunomodulatory, anti-diabetic and nephroprotective properties. The seed of this plant has shown anti-diabetic property proven in streptozotocin induced diabetes rat model.
Recently, Mahesh et al (2009) evaluated the anti-oxidant activity of aqueous extract of Terminalia chebula which protects the liver and kidney among aged rats. Reddy et al (2009) identified the novel compounds isolated from Terminalia chebula , are having the property to inhibit the COX and 5-LOX, the key enzymes involved in inflammation and carcinogenesis. In reference to metabolic syndrome, Singh et al., 2009 reported the significant effect of the fruit extract to control glucose lowering activity and to improve insulin sensitivity in animal models of type-2 diabetes mellitus.
Chemical Composition:
Fruits contain astringent substances—Tannic acid, Chebulinic acid, gallic acid etc. Resin and a purgative principle of the nature of anthraquinone and sennoside are also present. Anthaquinone glycoside, chebulic acid, tetrachebulin, linoleic acid palmitic acid are the chemical constituents found in the fruits of the plants. Tannic acid is a polymer of gallic acid molecules and glucose. Tannic acid will hydrolyze into glucose and gallic or ellagic acid units. The anti-oxidant and anti-mutagenic properties of tannic acid are beneficial.
Example-I
When the hydro-alcoholic extracts of Salacia reticulata in the dose of 30 mg/kg, Garcinia indica 15 mg/kg, Dioscorea bulbifera in the dose of 25 mg/kg and Terminalia chebula in the dose of 22 mg/kg body weight was combined and given to the (high fat diet model) experimentally induced obese rats showed body weight control, lipid lowering effects as well as serum insulin regulating role. The test formulation decreased the leptin level and increased the adiponectin concentrations following 3 months of treatment with formulation in comparison to control group.
Example-II
The hydro alcoholic extract of plant Salacia reticulata in the dose of 100 mg/kg and Dioscorea bulbifera in the dose of 50 mg/kg body weight in combined from exerted reduction in body weight and abnormal lipids, lipoprotein lowering activity along with improved systemic inflammation as measured through hsCRP, interleukin 6 and TNF-α estimation.
Example-III
In clinical trial program the test formulation revealed beneficial role on body weight control when the extract of Salacia reticulata (350 mg/day) and Dioscorea bulbifera (350 mg/day) was given to obese patients for 3 months. As it has shown there was a marked reduction in body mass index, skinfold thickness of various body parts without any adverse reaction.
Example-IV
When the hydro-alcoholic extract of Terminalia chebula in the dose of 250 mg/day, Garcinia indica in the dose of 250 mg/day and Dioscorea bulbifera in the dose of 300 mg/day was administered to obese patients reduction in interleukin-6 and TNF-α was noticed suggesting anti-inflammatory effects. Further, this combination of three plant extract also exerted improved insulin sensitivity, reduction in blood glucose level among obese subjects.
Example-V
When the hydro-alcoholic extract of Salacia reticulata in the dose of 450 mg/day, Terminalia chebula in the dose of 275 mg/day and Garcinia indica in the dose of 200 mg/day combined and given to selected obese patients for six months reduction in body weight along with reduced leptin and increase in adiponectin level was noticed suggesting the anti-obesity and drastic weight control role and improvement in atherosclerotic process following test formulation treatment.
Example-VI
When the hydro-alcoholic extract of Dioscorea bulbifera in the dose of 400 mg/day, Terminalia chebula in the dose of 275 mg/day and Garcinia indica in the dose of 300 mg/day was given in combined form revealed marked reduction in total cholesterol, LDL-C and triglycerides and also increase in HDL-c indicating anti-hyperlipidemic activity of test formulation.
Example-VII
When the hydro alcoholic extract of plant Dioscorea bulbifera in the dose of 350 mg/day, Terminalia chebula in the dose of 300 mg/day and Salacia reticulata in the dose of 375 mg/day to selected obese patients a significant improvement joint pain and work performance was noticed due to significant reduction in body weight and improved mental performance including feeling of well being, anxiety and depression of obese subjects.
Example-VIII
When the hydro-alcoholic extract of all four plants i.e. Salacia reticulata in the dose of 325 mg/day, Garcinia indica in the dose of 150 mg/day, Discoria bulbifera in the dose of 300 mg/day and Terminalia chebula in the dose of 175 mg/day administered orally in combined form exerted maximum beneficial effect as there was reduction in body weight, total cholesterol, LDL-c, triglycerides levels and increase in HDL-c was noticed. The test formulation also reduced the increased interleukin-6 level, leptin level and increased the adiponectin concentration among treated obese individuals.
The pre-clinical and clinical studies conducted by us suggested that test formulation is safe and can be given for longer time.
It is claimed that better results are obtained when the extract of all four plants i.e. Dioscorea bulbifera, Salacia reticulata, Terminalia chebula and Garcinia indica were mixed and given in combined form in specific doses, is a potent anti-obesity, anti-inflammatory, anti-hyperlipidemic drug including anti-atherosclerotic actions and thus test formulation has potential role in the regulation of bio-markers associated with obesity and involved with CHD risk. Thus the test formulation reduces body weight by 10-15 percent, controls the increase in body weight, reduces blood pressure, improves insulin sensitivity, reduces abnormal lipids and lipoproteins and ultimately prevents from coronary heart disease among obese patients. The test formulation is safe, can be administered for longer time among human subjects.
Experimental Evidence
Pre-Clinical Efficacy Study of the Test Formulation
This experimental study was carried out to study the effect of test formulation was evaluated on the high fat diet induced obesity followed by hypercholesterolemia, vascular inflammation and other associated complications, with the object to develop a new plant based formulation beneficial in the prevention an management of obesity and its future consequences.
High fat diet (24.72% fat) induced obesity and effect of test formulation Animals: Sprague dawley rats (both male and female) For this study Sprague Dawley rats of both sexes were procured from central animal house, IMS, BHU. Ethical approval was sought from Institutional Animal Ethics Committee. Rats were maintained under controlled condition (25° C., 12-hour light/dark cycle, 50% humidity) and fed either a standard chow diet or high fat diet (24.72% fat). The high fat palleted obesogenic diet was administered by ad-libitum access for six months. Study was divided in to three groups— Group-I 10 Animals were Fed standard diet Group-II 10 Animals were fed with high fat diet Group-III 10 Animals were fed with high fat diet and treated with test formulation

High Fat Diet Leads to—


Obesity, dyslipidemia, Insulin resistance, Increased systolic blood pressure, Endothelial dysfunction, glomerular nephritis, Decrease plasma adiponectin, Free Fatty acid.

Formulation


































The Ayurvedic test formulation has revealed significant effect on various biomarkers responsible for obesity like leptin and adiponectin. A high values of leptin and significant low values of adiponectin was the main laboratory finding among the selected obesity cases. It is observed that Ayurvedic test drug treatment reduces the leptin level and simultaneously, significant increase in adiponectin level indicated the anti-obesity property of test formulation. On comparison when the initial values are compared with 6 months values of the parameters, the changes are significant. It has been observed that the results are comparable with conventional treated group (Table 4, 5).

High triglycerides content was also estimated in those obese cases. Maximum cases showed triglycerides more than 300 mg/dl before starting the treatment. During 6 months study period the level declined in both the groups but reduction is more in Ayurvedic test formulation treated group (Table 6).

The increased level of endotheline and Apolipo B at initial stage indicated the risk of CHD among those cases due to endothelial dysfunction. It is observed that both endotheline and Apolipo B reduced drastically during study period (Table 7, 8). It is observed that the mode of action of present Ayurvedic formulation is through the regulation of leptin and adiponectin and thus reduces the adiposity, body fat and insulin resistance among obese individuals.
