Background of the Invention:
Obesity is excess body weight for a particular age, sex and height as a consequence of imbalance between energy intake and energy expenditure. The primary causes of obesity are one or more of the following disorders, which include overeating and inadequate exercise, some genetic disorders, underlying illness (e.g. Hypothyroidism), certain medications, sedentary lifestyle, a high glycemic diet (i.e., a diet that consists of meals that give high post prandial blood sugar), weight cycling (caused by repeated attempts to lose weight by dieting, eating disorders), stress and insufficient sleep.
During the past 20 years, obesity among adults has risen significantly in the United States. The latest data from the National Center for Health Statistics show that 30 percent of U.S. adults of 20 years of age and older, i.e. over 60 million people, are obese. The percentage of young people, who are overweight, has more than tripled since 1980. More than 16% of the children and teens aged 6-19 years, that is over 9 million young people, are considered overweight.
As per World Health Organization’s latest projections, approximately 1.4 billion adults (age 20+) were overweight. Of these overweight adults, over 200 million men and nearly 300 million women were obese. Thirty five percentage of adults aged 20 and over were overweight in 2008, and 11% were obese. Sixty five percentage of the world's population live in countries where overweight and obesity kills more people than underweight. In 2012, more than 40 million children under the age of 5 were overweight or obese (WHO's fact sheet No. 311, May 2014). WHO further projects that by 2015, approximately 2.3 billion adults will be overweight and more than 700 million worldwide will be obese. Obesity in Europe was recognized as a serious problem, with up to 27% of men, 38% of women and 3 million children are clinically obese. The obesity was not limited to developed countries, but it was rapidly becoming a problem in developing countries as well. The number of those affected, particularly children, are continuing to increase at an alarming rate. Obesity is already responsible for 2-8% of health care costs and 10-13% of deaths in different parts of Europe. Recent studies have shown that approximately a third of variance in adult body weights result from genetic influences. Leptin, an adipocyte and placenta-derived circulating protein, regulates the magnitude of fat stores in the body leading to obesity. Gastrointestinal peptides, neurotransmitters and adipose tissue may also have an etiologic role in obesity. Obesity and adipose tissue expansion increase the risk of hypertension, type 2 diabetes, arthritis, elevated cholesterol, cancer and serious hormonal imbalances in women, leading to sterility. Low caloric diets with or without exercise can help with temporary weight loss; however, diet and exercise alone have not proven successful for long-term solutions in weight management (H. G. Preuss, et al, Nutrition Research, 2004, 24, 45-48).
Obesity is the culmination of many underlying mechanisms. Obesity is characterized as uncontrolled adipose tissue mass in the body. An increase in adipose tissue can be the result of the production of new fat cells through the process of adipogenesis and/or the deposition of increased amounts of cytoplasmic triglyceride or lipid droplets per cell. In the adipogenesis process, proliferation of preadipocytes or precursor fat cells needs to be followed by the differentiation of these cells to the mature adipocyte phenotype. Increased lipid accumulation in the mature adipocyte cells is the most important feature of obesity disorder. Peroxisome Proliferator-Activator Receptor gamma (PPAR-?) is predominantly expressed in adipocytes and is a key determination factor for adipogenesis.
Fat is stored as triglycerides form in adipose tissue. The breakdown of this fat in fat cells into glycerol and fatty acids is known as lipolysis. During this process, free fatty acids are released into the bloodstream and circulate throughout the body. The hormones called epinephrine, norepinephrine, glucagon and adrenocorticotropic hormone induce lipolysis. Inhibition of the differentiation of pre-adipocytes into mature adipocytes leads to the reduction of new adipose tissue and reduction in the formation of fat reserves. Modulation of adipogenesis and lipolysis in humans may thus lead to reduction in the burden of obesity or overweight (excess body weight).
There are a few therapeutic interventions based on pharmaceutical drugs, such as phentermine (Fastin, Adipex P), for weight control but these methods exhibit side effects like high blood pressure, headache, insomnia, irritability and nervousness. The other important drug therapy for weight control is Xenical (Roche Pharm. Co. Ltd., Swiss), Reductil (Abbot Co. Ltd., USA). The most common side effects are gas, cramps and diarrhea, elevated blood pressure. All these therapies are based on active ingredients that are of synthetic origin. Effective anti-obese therapies with satisfactory efficacy and acceptable safety have not been developed so far.
More importantly, anti-obese agents of natural origin with proven safety are of great demand to control this growing menace. It is particularly advantageous for inhibition, amelioration and prevention of obesity if an anti-obesity action can be imparted to food products and beverages, which are ordinarily ingested.
Hence, presently there is great demand for development of natural agents for prevention, maintenance and remedy of obesity, which are safe and effective. The major emphasis now for many organizations around the globe has been to develop new dietary ingredients and compositions especially from natural origin. Herbal and natural products containing Gymnema extract, Garcinia extract, or carnitine are known to prevent fat accumulation through the inhibition of fat absorption, enhancement of fat decomposition, and the enhancement of fat consumption by the body.
The Alangium salvifolium (Alangeaceae) also called as ‘Ankola’ is extensively cultivated in India. It is a popular folk medicine and has been studied for its anti-inflammatory, antimicrobial, antifertility and cardiotonic activities. Traditionally, Alangium salvifolium seeds have been reported to exhibit a variety of biological activities, including anti-diabetic, anti-cancer, diuretic, anti-inflammatory, anti-microbial, laxative, and anti-epileptic activity. The phytochemical analysis of Alangium salvifolium revealed the presence of alkaloids, glycosides, terpenoids, steroids, tannins and the ethanol extracts of Alangium salvifolium seeds exhibited anti-diabetic, anti-epileptic, analgesic and anti-inflammatory activities (Sharma et al., Acta Pol Pharm. 68(6), 897, 2011). Anti-nociceptive and anti-inflammatory activities of Alangium salvifolium flower extract were proven in carrageenan and formalin induced paw edema models in mice (Zahan et al., Pak J Biol Sci. 16(19), 1040, 2013).

Detailed Description of the Invention:
The invention will now be described in detail in connection with certain preferred and optional embodiments, so that various aspects thereof may be more fully understood and appreciated.
In the adipogenesis process, proliferation of pre-adipocytes or precursor fat cells is followed by the differentiation of these cells into mature adipocyte phenotype. An increase in adipose tissue mass can be the result of the production of new fat cells through the process of adipogenesis and the deposition of increased amounts of cytoplasmic triglyceride or lipid droplets in the mature adipocyte cells per cell. Increased lipid accumulation is the most important feature of the adipogenesis process. The uncontrolled fat accumulation in the body during the metabolic process is predominantly driven by the over expression and increased activity of Peroxisome Proliferator-Activated Receptor-gamma (PPAR-?), a ligand activated nuclear receptor that act as a lipid sensor, integrating the homeostatic control of energy, lipid, and glucose metabolism. In addition, adipose differentiation related protein (ADRP), CD36, CEBPa, CEBPß and Perilipin are other important markers of adipogenesis process.
Lipolysis (adipolysis) is a catabolic process in adipose tissue leading to the breakdown of triglycerides stored in adipocyte cells and release of fatty acids and glycerol. The ß3-adrenergic receptor (ß3AR) is the principal receptor in body?s adrenergic system in the regulation of lipolysis and energy expenditure. Tightly regulated balance between lipid synthesis (adipogenesis or lipogenesis) and lipid mobilization (lipolysis) adjusts the fat storage level within cells.
Based on the above information, inventors of the present invention have undertaken the screening of a large number of herbal extracts to assess their inhibitory potential against the lipid accumulation and potential for acceleration of breakdown of stored fat in 3T3-L1 mouse adipocyte cells. It was found that the extracts and purified fractions of Alangium salvifolium fruit raw material exhibit potent anti-adipogenic and pro-lipolytic activity in 3T3-L1 mouse adipocyte cells. The ethanol extract (ASE03) of A. salvifolium showed 49.86% and 74.01% inhibition of lipid accumulation at 1 ?g/mL and 2.5 ?g/mL concentrations respectively. The other extracts also showed potent anti-adipogenesis activity as summarized in Table 1. Extracts of tender twigs of A. salvifolium also showed potent anti-adipogenic activity as summarized in Table 2. In addition, the ethanol extract also potently and dose dependently accelerated the lipolysis in 3T3-L1 adipocyte cells. It exhibited 24.12%, 44.7% and 64.71% increase in lypolysis at 5 ?g/mL, 25 ?g/mL and 50 ?g/mL concentrations respectively as shown in Table 3.
The inventors also found that the administration of one or more of the components selected from the extracts, fractions, active compounds derived from the herb Alangium salvifolium in a therapeutically effective amount in cell based studies potently ameliorated the levels of certain biomarker molecules or biological proteins that are altered during metabolic syndrome, obesity, diabetes, atherosclerosis, endothelial dysfunction, hypertension, hypercholesterolemia, fibromyalgia/chronic pain syndrome, ageing, neurodegenerative diseases and other disease conditions associated with metabolic syndrome.
It was observed that the ethanol extract of A. salvifolium (ASE03) potently modulated the levels of several adipocyte differentiation markers such as Peroxisome proliferator-activated receptor gamma (PPAR?), ADRP, CEBPa, CD36 and intracellular lipid droplet surface associated protein (perilipin) in a dose dependent manner in cellular studies performed using immunoblot assay as summarized and depicted in Figure II. The down regulation of these marker proteins in ASE03 treated adipocytes suggests that the ethanol extract of Alangium salvifolium fruit exerts multiple beneficial roles in controlling the adipogenic differentiation process; by (1) inhibiting cellular differentiation by down regulating Peroxisome proliferator-activated receptor ? (PPAR ?), which is a nuclear receptor that is expressed predominantly in adipose tissue, wherein it is known to play a critical role in adipocyte differentiation and fat deposition, (2) restricting cholesterol ester uptake by inhibiting CD36, which is a class B scavenger receptor known to function as a fatty acid transporter (FAT) and it facilitates the uptake of long-chain fatty acids (LCFAs) in adipocytes, (3) inhibiting adipose differentiation related protein (ADRP), which play possible role in the formation or stabilization of lipid droplets in adipocytes and enhances the uptake of long chain fatty acids by adipose tissue, (4) by down regulating other critical transcription factors of adipogenesis process, CEBP? (CCAAT/enhancing binding protein alpha) and CEBP? (CCAAT/enhancing binding protein beta), which along with PPAR? are known to cooperatively orchestrate adipocyte differentiation. These are proteins involved in different cellular responses like the control of cellular proliferation, growth, differentiation and metabolism. Together, these markers influence abdominal obesity and related metabolic abnormalities associated with type 2 diabetes and cardiovascular disease.
In addition to the foregoing adipogenesis markers, ASE03 also down regulates perilipin protein in adipocytes strongly indicating reduced fat store in the cytoplasm. Perilipin forms a protective coating around the lipid droplets in the fat-storing cells in adipose tissue and protects the stored lipids against body’s natural lipases, such as hormone-sensitive lipase (HSL). In presence of ASE03, the reduced perilipin coat exposes and increases susceptibility of the intravescicular lipids to HSL, which breaks down triglycerides into glycerol and free fatty acids by a process called lipolysis.
In futher cell based studies in 3T3-L1 adipocytes, ASE03 strongly and dose dependently down regulated the expressions of the key enzymes of fatty acid biosynthesis pathway i.e, FAS and ATP citrate Lyase in adipocytes. The results are summarized in Figure III. Thus, ASE03 potentially inhibit lipogenesis process in the fat tissue. Fatty acid Synthase (FAS) catalyzes fatty acid synthesis. It catalyzes the synthesis of palmitate from Acetyl-CoA and Malonyl-CoA in presence of NADPH. ATP citrate lyase is the primary enzyme responsible for the synthesis of cytosolic Acetyl-CoA. Acetyl-CoA is the precursor for fatty acid synthesis.
In continuation studies, the inventors also observed that the extracts of Alangium salvifolium can potentially modulate the phosphorylation of AMPK at Thr172 in HepG2 human hepatocytes. The treatment of HepG2 human hepatocytes with Alangium salvifolium ethanol extract (ASE03) potently and dose dependently up regulated the AMPK phosphorylation (Figure IV). This indicates that ASE03 can induce AMPK activation in HepG2 human hepatocytes.
AMPK has been considered as the master regulator of metabolic/energy homeostasis in the body via controlling glucose and fat metabolism. Upregulation of AMPK activity by the extracts of Alangium salvifolium indicates the following therapeutic potential for them against:
1) Type 2 or insulin resistant diabetes (as AMPK activation increases cellular glucose uptake via. increasing glucose uptake).
2) Obesity and over weight (as AMPK increases thermogenesis via enhanced fatty acid Oxidation; and decreased fatty acid synthesis).
3) Atherosclerosis, Hypertension and Hypercholesterolemia (as AMPK reduces cholesterol synthesis by inhibiting HMG-Co-A Reductase activity).
4) Fibromyalgia or chronic pain syndrome (as AMPK via improving mitochondrial function through increased expression of Peroxisome Proliferator-Activated Receptor gamma coactivator-1 alpha or PGC-1a).
5) Ageing and neurodegenerative diseases (as AMPK increases mitochondrial biogenesis and ROS detoxification by inducing PGC-1a synthesis).
6) AMPK activators are also useful for the supplements for sports nutrition as it up-regulates mitochondrial biogenesis, thus increasing the capacity of tissues for aerobic production of ATP.
In a repeated study, it was confirmed that ASE03 positively modulates AMPK activity in HepG2 human hepatocytes. As depicted by representative immunoblots summarized in Figure V, ASE03 up regulates AMPKa phosphorylation at Thr172 in HepG2 human hepatocytes. ASE03 treatment also demonstrated hyper phosphorylation of Acetyl CoA Carboxylase at Ser79. Hyperphosphorylation at Thr172 activates AMPK, which in turn phosphorylates Ser79 of Acetyl CoA Carboxylase (ACC), the downstream effector molecule of AMPK. Hyper-phosphorylation at the active site switches off ACC activity. Deactivation of ACC is considered as an indicator for AMPK activation. Hence, activation of AMPK turns on several metabolic pathways, such as stimulation of hepatic fatty acid oxidation and ketogenesis, muscle glucose uptake, insulin secretion; on the other hand it inhibits cholesterol synthesis, lipogenesis, and triglyceride synthesis etc. Together, our observation indicates that ASE03 activate AMPK pathway and thus might help in reducing hyperglycemia via increasing insulin sensitivity, decreasing obesity via reducing lipogenesis, reducing hypercholesterolemia, triglyceride synthesis etc.
Unexpectedly, ASE03 was also found to upregulate CPT-1a expression in HepG2 human hepatocytes. The data is summarized in Figure VI. Carnitine palmitoyltransferase I? (CPT-1a) is the key enzyme in beta-oxidation of long chain fatty acids. CPT-1a is the first component and rate-limiting step of the carnitine palmitoyltransferase system, catalyzing the transfer of the acyl group from coenzyme A to carnitine to form palmitoylcarnitine. A translocase then shuttles the acyl carnitine across the inner mitochondrial membrane where it is converted back into palmitoyl-CoA and proceeds for beta-oxidation. Hence, by inducing CPT-1? expression in hepatic cells, ASE03 can be helpful in decreasing adiposity via increasing mitochondrial fat burning, and reducing fatty liver (hepatic steatosis).
Surprisingly, the HepG2 hepatocyte cells treated with ASE03 also showed up-regulated phosphorylation of HMG CoA Reductase (HMGCR). The data is summarized in Figure VII. HMG CoA Reductase (HMGCR) is a rate limiting enzyme in the mevalonate pathway leading to cholesterol biosynthesis. This enzyme is in activated state when it is dephosphorylated; conversely, inhibition of HMGCR is achieved by its phosphorylation at Ser872. In the metabolic pathway, AMPK plays a crucial role in regulation of HMGCR activity. Upon activation, AMPK phosphorylates and inactivates acetyl-CoA carboxylase, the rate-limiting enzyme of fatty acid biosynthesis; and inactivate HMGCR through phosphorylation at Ser872. Hence, our observation strongly suggests that ASE03 can help in reducing hypercholesterolemia/hypertension via limiting the cholesterol biosynthesis.
A. salvifolium extracts can thus be useful for the prevention, treatment and control of overweight, obesity, metabolic syndrome and other metabolic disorders through the modulation of one or more metabolic biomarkers. These non-limiting biomarkers include Peroxisome proliferator-activated receptor gamma (PPAR?), Adipose Differentiation Related Protein (ADRP), CCAAT/enhancer-binding protein alpha (CEBPa), CCAAT/enhancer-binding protein beta (CEBPß), adipocyte CD36, Monocyte Chemotactic protein (MCP-1), Oxidized LDL (Ox-LDL), adipocyte fatty-acid-binding protein (aP2/FABP4/A-FABP), beta-3 Adrenergic Receptor (ß3AR), Perilipin, Adiponectin, Protein tyrosine phosphatase-1B (PTP-1B), AMPK, Fatty Acid Synthase, ATP citrate Lyase, Acetyl CoA Carboxylase (ACC), Carnitine palmitoyltransferase I (CPT-1?) and HMG CoA Reductase (HMGCR). The non-limiting metabolic processes include adipogenesis, adipolysis, fat synthesis and cholesterol synthesis.
The efficacy shown by the extracts of Alangium salvifolium in in vitro models against obesity and other metabolic disorders was further evaluated in an in vivo model of obesity. Obesity was induced in male Sprague Daley rats by supplementing the rats with High Fat Diet (HFD) for six weeks and the obese rats were then treated with one of the test substances for eight weeks of treatment period. The composition ASE03F1 containing the ethanol extract (ASE03) derived from A. salvifolium fruit dose dependently inhibited the body weight gain in high fat diet induced obese rats. ASE03F1 exhibited 22.29% % and 68.70% reduction in body weight gain in the treatment groups supplemented with 200 mg/kg body weight and 400 mg/kg body weight of ASE03F1 respectively. Sibutramine as a positive control showed 91.84% reduction in body weight gain. The results of body weight gain for the treatment groups and control group are summarized in Figure VIII. In addition, ASE03F1 treatment also significantly reduced serum LDL, triglycerides (TG) and cholesterol levels. It also reduced Atherogenic index and Coronary artery index. The efficacy data for Clinical Biochemistry is summarized in Figure IX. Atherogenic Index (TC/HDL) is the ratio of Total cholesterol and High density lipoprotein, while Coronary artery index (LDL/HDL) is the ratio of Low density lipoprotein and High density lipoprotein. Both these indices give prediction about cardiovascular disease. The treatment with ASE03F1 is without risks as no atypical signs were observed in animals throughout treatment phase. In conclusion, these results suggested that ASE03F1 can be very potent for controlling and treating obesity, overweight, metabolic syndrome and other disease conditions associated metabolic syndrome.
The ethanol extract of Alangium salvifolium was subjected to purification over silica gel using solvents of increasing polarity starting from ethylacetate/hexane mixtures through ethylaceate and methanol/ethylacetate mixtures to methanol to obtain eight fraction ASE03/01 to ASE03/08. Some of the fraction were subjected to repeated purification on silica gel or reversed phase silica gel to obtain pure compounds. Some of the compounds are characterized as betulinic acid (1), demethylalangiside (2), psychotrine (3), deoxytubulosine (4) and alangiside (5), loganic acid (6), tubulosine (7), cephaeline (8), salsoline (9) and deacetylipicosidic acid (10), 6-O-methyl-N-deacetyl-6??-O-?-glucopyranosyl-isoipecosidic acid (11). The structures are depicted in Figure I. The some of the fractions and compounds exhibited potent anti-adipogenesis (inhibition of lipid accumulation) and pro-adipolysis (acceleration of lipolysis) activities as summarized in example 14 and Table 4.
Several compositions were prepared by combining ethanol extract of Alangium salvifolium and extracts derived from selected palnt extracts. The compositions ASE03F2 to ASE03F7 disclosed in the experimental (example 9) were evaluated for their efficacy to inhibit the lipid accumulation in 3T3-L1 mouse adipocyte cells. All the compositions strongly inhibited the lipid accumulation in adipocyte cells as summarized in example 15 and Table 5, suggesting their potent anti-adipogenesis activity and potential use for treating overweight and obesity, and other metabolic disorders.

The specifically immuno-reactive proteins were detected by using phospho (Thr172) - specific and wild type AMPK antibody (Cell Signaling Technology, USA). The immuno-blots were developed by using chemiluminescent West-Pico substrate (Thermo Scientific, USA). The blotted membranes were also reacted with actin specific antibody (Sigma Chemicals, USA) to ensure equal protein loading. The expressions of the immuno reactive protein bands were analyzed by Image Lab Software, version 2.0.1 (BioRad, USA).
Immunoblot analysis revealed that the ethanol extract of Alangium salvifolium (ASE03) up regulated phosphorylation at Thr172 of AMPKa in a dose dependent manner (Figure IV). Hyper-phosphorylation at Thr172 of AMPKa is crucial for activation of its protein kinase activity.

Cell culture and treatments:
For PPAR?, ADRP, CEBPa, CD36, Perillipin, FAS, ATP Citrate Lyase: Mouse pre-adipocyte 3T3-L1 cells are maintained in Dulbecco’s Modified Eagles Medium (DMEM) supplemented with 2 mM glutamine, 4.5g/L glucose and 10% fetal bovine serum. Equal number of cells was plated in each well of 24-well culture plates. Cells were pre-treated with multiple concentrations of ASE03 for 2h and followed by addition of differentiation medium containing 500nM insulin, 1.0µM dexamethasone, and 0.5mM isobutylmethylxanthine (IBMX) for 48h. Thereafter, cell were further incubated with post differentiation medium (DMEM containing 100nM insulin) in presence or absence of ASE03 for three days. Vehicle control cultures received only 0.2% DMSO.
For AMPK/p-AMPK (Thr172), ACC/p-ACC (Ser79), CPT1a, HMGCR: Equal number of HepG2 human hepatocytes (ATCC, Manassas, VA) suspended in DMEM containing 10% FBS was plated in each cell culture dish. After attachment, the cells were serum starved in DMEM containing 1% FBS for 24hrs. Then the cells were treated with 1µg/ml of ASE03 for various time periods.
Following various treatments with ASE03, the cells were placed on ice and washed thrice with chilled phosphate buffered saline. Thereafter, the cells were lysed in cell lysis buffer; and the cell lysates were clarified at 14000g for 10 min at 4oC. The protein content in cell lysates was estimated using BCA protein assay kit (Thermo Scientific, USA). Modulations in various protein expressions in the cell lysates were analyzed using immunoblot assays.
Immunoblot assay: Briefly, equal amount of cell lysate proteins was run in SDS-PAGE and the resolved proteins were electro-blotted onto nitrocellulose membranes. The specific immuno-reactive proteins were detected by using appropriate antibodies. The antibodies against PPAR?, ADRP, CEBPa, CD36, Perillipin, FAS, ATP Citrate Lyase, AMPK/p-AMPK (Thr172), ACC/p-ACC (Ser79), CPT1a, HMGCR were purchased from Cell Signaling Technology (Danvers, MA, USA). Antibodies specific to Phospho-HMGCR (Ser872) and Actin were purchased from Merck Millipore (Darmstadt, Germany) and Sigma-Aldrich (St. Louis, MO). The immuno-blots were developed by using chemiluminescent West-Pico substrate (Thermo Scientific, USA). The blotted membranes were also reacted with actin specific antibody (Sigma Chemicals, USA) to ensure equal protein loading. The expressions of the immuno reactive protein bands were analyzed with help of Image Lab Software, version 2.0.1 (BioRad, USA).
ASE03 down regulates adipocyte differentiation marker proteins in 3T3 adipocytes
Results and Significance: ASE03 potently down regulates PPAR?, ADRP, CEBPa, CD36 and perilipin, the marker proteins of Adipogenesis differentiation processes in 3T3-L1 adipocytes. The data is summarized in Figure II. Transformation of preadipocytes to mature adipocytes is tightly controlled by differentiation process and is modulated by members of two families of transcription factors, the CCAAT/enhancer binding proteins (CEBPa) and peroxisome proliferator-activated receptors (PPARs). The formation of white adipose tissue is completely dependent on PPAR? and CEBPa. Key PPAR? target proteins such as Adipocyte differentiation related protein (ADRP), CD36, perillipin are heavily expressed as adipocyte specific proteins during the differentiation process. Overall, the data indicate that ASE03 strongly inhibits the adipocyte differentiation process by down regulating the key transcription factors and their target proteins.
ASE03 down-regulates lipogenesis in 3T3-L1 adipocytes
Results and Significance: ASE03 down regulated the expression of key enzymes responsible for lipogenesis in adipocytes. Representative immunoblots summarized in Figure III indicate that ASE03 dose-dependently down-regulates the expression of Fatty Acid Synthase (FAS) and ATP Citrate Lyase in 3T3-L1 adipocytes. Fatty acid Synthase (FAS) catalyzes fatty acid synthesis. It catalyzes the synthesis of palmitate from Acetyl-CoA and Malonyl-CoA in presence of NADPH. ATP citrate lyase is the primary enzyme responsible for the synthesis of cytosolic Acetyl-CoA. Acetyl-CoA is the precursor for fatty acid synthesis. Thus, by strongly down regulate the expressions of the key enzymes of fatty acid biosynthesis pathway i.e, FAS and ATP citrate Lyase in adipocytes, ASE03 potentially inhibits lipogenesis process in the fat tissue.
Modulation of metabolic marker proteins AMPK and ACC in ASE03 treated HepG2 human hepatocytes
Results and Significance: ASE03 positively modulated AMPK activity in HepG2 human hepatocytes. Representative immunoblots depicted in Figure V indicate that ASE03 up regulates AMPKa phosphorylation at Thr172 in HepG2 human hepatocytes. ASE03 treatment also demonstrated hyper phosphorylation of Acetyl CoA Carboxylase at Ser79. AMPK has been considered as the master regulator of metabolic/energy homeostasis. Hyperphosphorylation at Thr172 activates AMPK, which in turn phosphorylates Ser79 of Acetyl Co Carboxylase (ACC), the downstream effector molecule of AMPK. Hyper-phosphorylation at the active site switches off ACC activity. Deactivation of ACC is considered as an indicator for AMPK activation. Activation of AMPK turns on several metabolic pathways, such as stimulates hepatic fatty acid oxidation and ketogenesis, muscle glucose uptake, insulin secretion; on the other hand it inhibits cholesterol synthesis, lipogenesis, and triglyceride synthesis etc. Together, this data indicates that ASE03 activate AMPK pathway and thus might help in reducing hyperglycemia via increasing insulin sensitivity, decreasing obesity via reducing lipogenesis, reducing hypercholesterolemia, triglyceride synthesis etc.
ASE03 up-regulates carnitine palmitoyltransferase-1a (CPT-1a) expression in hepatocytes
Results and Significance: ASE03 strongly up regulated CPT-1a expression in HepG2 human hepatocytes. The data is summarized in Figure VI. Carnitine palmitoyltransferase I is the first component and rate-limiting step of the carnitine palmitoyltransferase system, catalyzing the transfer of the acyl group from coenzyme A to carnitine to form palmitoylcarnitine. A translocase then shuttles the acyl carnitine across the inner mitochondrial membrane where it is converted back into palmitoyl-CoA and proceeds for beta-oxidation. Thus, CPT-1a is the key enzyme in beta-oxidation of long chain fatty acids. Our observation indicates that ASE03 induced CPT-1a expression in hepatic cells, suggesting that ASE03 might help in decreasing adipocity via increasing mitochondrial fat burning, and also help in reducing fatty liver (hepatic steatosis).
ASE03 up-regulates 3-hydroxy-3-methyl-glutaryl-CoA reductase (HMGCR) phosphorylation in hepatocytes
Results and Significance: ASE03 up-regulated phosphorylation of HMG CoA Reductase (HMGCR) in hepatocytes. The data is summarized in Figure VII. HMG CoA Reductase (HMGCR) is a rate limiting enzyme in the mevalonate pathway leads to cholesterol biosynthesis. This enzyme is in activated state when it is dephosphorylated; conversely, inhibition of HMGCR is achieved by its phosphorylation at Ser872. In the metabolic pathway, AMPK has a crucial role in regulation of HMGCR activity. Upon activation, AMPK phosphorylates and inactivates acetyl-CoA carboxylase, the rate-limiting enzyme of fatty acid biosynthesis; and inactivate HMGCR through phosphorylation at Ser872. However, our observation strongly suggests that ASE03 might help in reducing hypercholesterolemia/hypertension via limiting the cholesterol biosynthesis.

Example 16: Anti-obese activity of the composition ASE03F1:
Efficacy of ASE03F1 in comparison with sibutramine was tested in High Fat Diet induced obesity model of Sprague-Dawley rats.
Induction: Selected healthy Sprague-Dawley rats of 7-8 weeks were made obese experimentally through dietary intervention during the six weeks induction period by feeding high fat diet (60% kcal fat diet supplied by Research Diets Inc., USA, cat. No. D12492) ad libitum. Naïve control group containing 9 animals were fed standard died. Body weights were measured on weekly basis. Obese animals, which showed more than 45% weight increase in body weight by the last day of 6th week induction period were selected for the study and they are randomly divided in to four groups (G1 to G4) with 9 animals in each group. Animals were then shifted to Nutrilab-Rodent standard diet throughout treatment phase.
Treatment: Following 6 weeks of induction phase, the animals were treated orally (using oral feeding gavage) with allocated test substances or vehicle daily for 8 weeks. The control group (G1) rats were administered vehicle (10 mL of 0.5 % CMC-Na) and treatment groups were supplemented with 200 mg of ASE03F1 (G2), 400 mg of ASE03F1 (G3) or 10 mg of positive control, sibutramine (G4) all in 10 mL of 0.5% CMC-Na on daily basis for 8 weeks.
Body weights: Body weight of individual animal was recorded weekly during the entire duration of the study. Mean body weights for the treatment groups and control group were determined. The body weight gain was calculated at the end of 1st week, 4th week and 8th week after initiation of treatment in comparison to initial body weights. The food intake, clinical biochemistry and Oral Glucose Tolerance Test (OGTT test) were also evaluated for all the animals. In clinical biochemistry total cholesterol (TC), low density lipoproteins (LDL), high density lipoproteins (HDL), triglycerides (TG), alanine aminotransferase and aspartate aminotransferase levels were analyzed with conventionally available kit methods using ILab Aries automatic biochemistry analyzer (Milano, Italy). In OGTT test, Blood sampling was performed by tail clipping and blood glucose level was estimated at pre dose (0 minute) and thereafter on 30, 60, 90 and 120 minutes (post dose) by using glucometer (ACCU - CHEK Active). Outcome of the obesity induction and treatment efficacy was assessed by using derived parameters like body weight gain and percentage body weight gain. Body weight gain was calculated by using formula (body weight on day X – body weight on day 0).
Results and Discussion: Supplementation of ASE03F1 for 8 weeks to obese rats resulted in significant reduction in percentage body weight gain. ASE03F1 dose dependently inhibited the body weight gain in high fat diet induced obese rats. It exhibited 22.29% % and 68.70% reduction in body weight gain in the treatment groups supplemented with 200 mg/kg body weight and 400 mg/kg body weight of ASE03F1 respectively. Sibutramine as a positive control showed 91.84% reduction in body weight gain. The results of body weight gain for the treatment groups and control group are summarized in Figure VIII. In addition, ASE03F1 treatment also reduced serum LDL, triglycerides (TG) and cholesterol levels. It also reduced Atherogenic index, Coronary artery index. The efficacy data for Clinical Biochemistry is summarized in Figure IX. Atherogenic Index (TC/HDL) is the ratio of Total cholesterol and High density lipoprotein while Coronary artery index (LDL/HDL) is the ratio of Low density lipoprotein and High density lipoprotein. Both these indices give prediction about cardiovascular disease. The treatment with ASE03F1 is without risks as no atypical signs were observed in animals throughout treatment phase. In conclusion, these results suggested that ASE03F1 can be very potent for controlling and treating obesity, overweight and other disease conditions associated metabolic syndrome. ,CLAIMS:We Claim,
