FIELD OF INVENTION:

This invention relates generally to the new phytochemical compositions for reducing or preventing mammalian obesity. In particular, the invention relates to novel, synergistic compositions comprising enriched demethylated curcuminoids, extract of Moringa oleifera, extract of Murraya koenigi and biologically acceptable carrier or diluents for reducing or preventing adipose tissue mass, inflammation and free radical mediated disorders.

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 cause of obesity is either due to overeating, inadequate exercise or eating disorder, 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. Although, the US national health objectives for the year 2010 is to reduce the prevalence of obesity among adults to less than 15%, current data indicate that the situation is worsening rather than improving http://www.cdc.gov/nchs/products/pubs/pubd/hestats/overweight/overwght_adult_03.ht m). 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
(http://ec.europa.eu/health/ph_determinants/life_style/nytrition/green_papemutritiongp_c ol83_en.pdf). The obesity was not limited to developed countries, but it was rapidly becoming a problem in developing countries as well.

As per World Health Organisation's (WHO) latest projections, approximately 1.6 billion adults (age 15+) were overweight and at least 400 million adults were obese globally in 2005. WHO further projects that by 2015, approximately 2.3 billion adults will be overweight and more than 700 million will be obese (WHO's fact sheet No. 311, September 2006, http://www.who.int/mediacentre/factsheets/fs311/en/index.html).

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. Obesity also increases the risk of, dyslipidemia (for example, high total cholesterol or high levels of triglycerides), gallbladder disease, osteoarthritis, sleep disorders, respiratory problems, arteriosclerosis and heart failure.

Obesity is the culmination of many underlying mechanisms. Obesity is characterized as uncontrolled adipose tissue mass in the body and recognized as the fastest growing metabolic disorder in the world. An increase in adipose tissue mass 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 preadipbcytes 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-y) 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. The body's adrenergic system plays a
major part in regulating energy expenditure and lipolysis. In this process catecholamines mobilize energy-rich lipids by stimulating lipolysis in fat cells and thermogenesis in brown adipose tissue and skeletal muscle. It is known that PPAR alpha plays an important role in regulating lipolysis through the control of lipid metabolic enzymes such as lipoprotein lipase (LPL) (Beisiegel U., Proc. Natl. Acad. Sci., USA, 96, pp 13656-13661, 1999).

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). In addition, supplementation with drugs that suppress appetite, reduce food intake, reduce dietary fat absorption, increase energy expenditure and effect nutrient partitioning or metabolism have potential efficacy but they are unfortunately accompanied by adverse side effects (C. A. Haller and N. L, Benowitz., New England J. Medicine, 2000, 343, 1833-1838). The pharmaceutical drug, such as phentermine (Ffistin, Adipex P), is prescribed for weight control but it exhibits side effects like high blood pressure, headache, insomnia. Irritability and nervousness. The other important drugs for weight control are Xenical (Roche Pharm. Co. Ltd., Swiss) and Reductil (Abbot Co. Ltd., USA), which cause gas generation, cramps, diarrhea and elevated blood pressure, common side effects. All these therapies are based on active ingredients that are of synthetic origin.

Effective anti-obese therapies with satisfactory efficacy and acceptable safety have been long overdue. More importantly, anti-obese agents of natural origin with proven safety are greatly needed to control the growing menace. Many herbal and natural products containing gymnema extract, garcinia extract, or carnitine, for example 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. 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.
It is therefore an object of the present invention to provide a non-toxic dietary supplement composition comprising enriched demethylated curcuminoids from Curcuma longa alone or at least two of the compounds or extracts selected from enriched demethylated
curcuminoids, Mornga oleifera and Murraya koenigii and optionally containing other Ingredients.

A yellow pigmented fraction isolated from the rhizomes of Curcuma longa contains curcuminoids belonging to the dicinnamoyl methane group. They are considered the most important active ingredients and are believed to be responsible, for the biological activity of Curcuma longa. Though their major activity is anti-inflammatory, curcuminoids have been reported to possess antioxidant, antiallergic, wound healing, antispasmodic, antibacterial, antifungal, antitumor and anti-HIV activity as well. The major curcuminoids isolated from Curcuma longa include curcumm, demethoxycurcumin and bisdemethoxycurcumin. Curcuminoids may be found in other botanicals in addition to Curcuma longa, such as Cwcuma xanthorrhiza and Curcuma zedoaria. Curcuminoids are well known for their anti-inflammatory activity. Turmeric is one of the oldest anti¬inflammatory drugs used in Ayurvedic medicine. Demethylated curcumin, a minor curcuminoid from Curcuma /ongo is highly potent compared to the curcuminoids (Mazumder, A.; Neamati, N.; Sunder, S.; Schulz, J.; Pertz, H.; Eich, E.; Pommier, Y. J. Med. Chem. 1997, 40, 3057). The pharmacokinetics involving the safety, toxicity, dose range and biological properties of turmeric and its components, including curcumin is known.

The anti-inflammatory properties of curcumin were shown to inhibit the 5-lipoxygenase activity in rat peritoneal neutrophils as well as the 12-lipoxygenase and the cyclooxygenase activities ip human platelets (Ammon, H. P. T. et al, J. Ethopharmacol, 1993, 38, 113-119). Curcumin had no significant effect on quercetin-induced nuclear DNA damage, lipid peroxidation and protein degradation and thus has the unique potential of acting as both pro- arid antioxidants, depending on the redox state of their biological environment (Saura, C. et al., Cancer Letters, 1992,63,237-241).

Among the bibliographic references of the most interesting patents existing in the diata banks, application FR2,655,054 about the cellular protection agents contained in curcuminoids obtained from Curcuma longa, ascorbic acid and/or dismutase super oxide (DSO) stands out. Curcuminoids have a known aritioxidizing effect, as well as ascorbic acid and DSO that carry out a synergic effect.

The Moringaceae is a single genus family with 14 known species. Of these, Moringa oleifera Lam. (syns: Moringa pterygosperma Gaertn) is the most widely known and utilized species. The tree ranges in height from 5-12 m with an open, umbrella shaped crown, straight trunk (10-30 cm thick) with corky, whitish bark. A native of the sub-Himalayan regions of North West India, Moringa oleifera (M. oleifera) is now indigenous to many countries in Africa, Arabia, South East Asia, the Pacific and Caribbean Islands

and South America. It is now being cultivated in the tropical and subtropical areas around the worldwide (Sastri, B. N. The Wealth of India, CSIR, New Delhi, India, 1962, 425-429; Jahn, S. A. A. J. Am. Water Works Association, 1988, 80,43). M. oleifera commonly known as the 'horse-radish' tree (arising from the taste of a condiment prepared from the roots) and 'drumstick' tree (arising from the shape of the pods) and with many other vernacular names, indicating its significance around the world.

The leaves, pods, seeds, flowers, and roots of the Moringa oleifera tree are edible. The leaves have been proved by scientific research to be a powerhouse of nutritional value. It contains 7 times the vitamin C in oranges, 4 times the calcium in milk, 4 times the vitamin A in carrots and 2 times the protein in milk. Even though the tender pods, commonly known as 'Drumstick' are considered a prized vegetable for culinary preparations, the tender leaves are also used for curry preparation.

Moringa is one of the most useful plant used as food and in indigenous system of medicine (Nadkamij K. M., revised by Nadkami, A. K. The Indian Materia Medica, Popular Prakasan, Bombay, p 810, 1976). It also has medicinal importance in folk medicine for treatment of variety of human ailments like rheumatism, paralysis, epilepsy (Chopra, R. N., Nayer, S. L., Chopra, I. C, Glossary of Indian Medicinal Plants, CSIR, New Delhi, pi70,1956).

Murraya koenigii, more commonly known as curry leaf, is a small tree growing upto 4-6 m tall, with a trunk up to 40 cm diameter. The flowers are small white, and fragrant. The small black, shiny berries are claimed to be edible, but their seeds are poisonous. The
curry tree is native to India; today found almost everywhere in the Indian subcontinent excluding the high altitudes of the Himalayas (B. N. Sastry et. al.. The Wealth of India, CSIR, New Delhi, 1962, Vol. 6, pp 448-450).

Curry leaf is an essential leafy spice used in Asian cuisines for its distinct flavor. It has prominently been used a folk medicine in India and other Asian countries as an analgesic, astringent, antidysenteric, febrifuge, hypolipidemic and hypoglycemic agent. It is a powerful antioxidant and used for improvement of vision. It has also been used to treat night-blindness, and for regulation of fertility. The green leaves are stated to be eaten raw for curing dysentery, and the infusion of the washed leaves stops vomiting. The leaves, the bark and the roots of Murraya koenigii can be used as a tonic for stomachic. The green leaves are stated td be eaten raw for curing dysentery, and the infusion of the washed leaves stops vomiting. A toxicity study showed that methanolic extract was
moderately toxic (LD5o=316.23 mg/kg body weight) to rats (A. C. Adebajo, et. al, Phytomedicine, 2006, 13, 246-54). However Murraya koenigii has a history of hundreds of years of culinary usage by many cultures in the Eastern part of the globe.

The volatile low molecular compounds such as: p-caryophyllene, P-gurjunene, P-elemene, P-phellandrene , P-thujehe, a-selinene, P-bisabolene, limonene, p-trans-ocimene and p-cadinene in the essential oil are mostly responsible for the characteristic aroma of curry leaves (Christopher and Suzanne, Phytochemistry, 1982, 21, 1653; G. R. Mallavarapu, et. al., J. Essential Oil Res,, 1999, 11, 176-178). Garbazole alkaloids, 9-carbethoxy-3-methylcarbazole 9-formyl-3-methylcarbazole and 3-methyl-carbazole and another alkaloid murrayacinine were isolated from the roots of Murraya koenigii (M. Chakrabarty, et. al, Phytochemistry, 1997, 46, 751-5; B. S. Joshi, et. al., Tetrahedron, 1970,26, 1475-1482). A quality study indicated that the fresh curry leaves obtained from the three New England states contained 9744 ng of lutein, 212 ng of alpha-tocopherol, and 183 ng of beta-carotene per gram fresh weight.

Administration of curry, leaves to alloxaii and STZ induced diabetic rats showed hypoglycemic and anti-hyperglycemic effect. (S. Yadav, V. Vats, Y, Dhunnoo, J. K. Grover, J. Ethnopharmacol, 2002, 82, 111-16), The murraya carbazole alkaloids named murrayanine and 8,8'-biskoenigine showed antiosteoporotic activity (Y. S. Wang, et. al., J. Nat. Prod., 2003, 66, 416-8). The carbazole alkaloids also showed mosquitocidal and antimicrobial activities and exhibited topoisomerase I and II inhibition activities (R. S. Ramsewak, et. al., J. Agric. Food Chem., 1999, 47, 444-7). Curry leaf reduces blood cholesterol and glucose levels in ob/ob mice. The leaves showed potent antioxidant activity both in vitro and in vivo (Y. Tachibana, et. al., J. Agric. Food Chem., 2003, 51, 6461-67).

In the adipogenesis process, proliferation of preadipocytes heeds 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 this maturation process.

The uncontrolled fat accumulation in the body during the metabolic process is predominantly driven by the following key events. l).Over expression and increased activity of Protein Tyrosine Phosphatase IB during the differentiation process of preadipocytes to mature adipocytes, 2). Highly increased lipid accumulation was noted in the differentiated mature adipocytes, 3). Over expression and increased activity of Peroxisome Proliferator-Activated Receptor-gamma (PPAR-y,) a ligand activated nuclear receptor that acts as a lipid sensor, integrating the horneostatic control of energy, lipid, and glucose metabolism.
Themiogenesis is a metabolic process in which calories consumed and stored as fat by the body are expended to dissipate energy as a heat. This metabolic process primarily occurs in adipocytes, such as brown adipose tissue. Stimulation of thermogenesis causes fat cells to bum energy and a consequence of this can be loss of body weight.

More importantly, anti-obese agents of natural origin with proven safety are greatly needed to control the 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.

Based on the above information, inventors of the present invention have undertaken screening strategy of many plant extracts using in vitro cell based experimental protocols followed by in vivo experimental studies and found that demethylated curcuminoid and
extracts or fractions of Moringa oleifera and Murraya koenigii exhibit potent anti-adipogenic action by inhibiting lipid accumulation in vitro. The enriched demethylated curcuminoid extract and extract of Murraya koenigii also exhibit potent pro-lipolytic activity, A composition containing these three exhibited -synergistic anti-adipogenic activity, which is the subject matter of the present invention.

Accordingly, synergistic anti-adipogenic and pro-lipolytic compositions for the prevention and amelioration of adipogenesis and lipolysis mediated diseases, comprising at least two extracts selected from enriched demethylated curcuminoids obtained from Curcuma longa, methanol extract of Moringa oleifera and 60% methanol extract of Murraya koenigii along with one or more biologically acceptable carriers and optionally containing one or more of known anti-obesic agents.

A composition of demethylated curcuminoids 95%, methanol extract oi Moringa oleifera and 60% methanol extract of Murraya koenigii was tested for their protective efficacy and therapeutic efficacy against diet induced obesity in Sprague-Dawley rats (figures 1 and 2). This composition conferred significant protection from weight gain in diet induced obese animals (figure 1). It has also shown therapeutic efficacy against diet induced obesity (figure 2).

Adipose tissue is the primary source of circulating leptin and as the adipose tissue mass increases more leptin is produced in obese people. In controlled condition, it was proved that higher levels of adiposity were associated with high concentration of serum leptin. Thus the circulating leptin appears to be one of the best biological markers of obesity and that hyper lepinemia is closely associated with several metabolic disorders.

Therefore, the inventors further investigated the serum leptin levels in the treatment group. The reduction in serum leptin levels observed in the treatment group of animals supplemented with anti-adipogenic products of the present invention compared to that of controlled group may be taken as a measure of reduction in the visceral fat tissue mass and an additional indicator for the efficacy of therapeutic agent. The animals supplemented with a. composition. of demethylated curcuminoids 95%, extracts of

Moringa oleifera and Murraya koenigii showed significant reduction in serum leptin concentration (Figure 3) confirming its anti-adipogenic effect in animals.

The invention further relates to the use of enriched demethylated curcuminoids from Curcuma longa and its dietary/pharmaceutical preparations administered to an obese animal, including human, produces a therapeutic benefit in regulating body weight.

Assessment of inhibition of lipid accumulation in differentiated adipocytes: One hundred thousand 3T3-L1 Human pre-adipocyte cells in Dulbeccos Modified Eagles Medium (DMEM) containing 10% Fetal Bovine Serum (FBS) were taken into each well of a 24-well plate and incubated for 48h at 37°C and 5% CO2. The differentiation of pre-adipocyte cells was initiated in a differentiation medium containing 10 ^g/ml insulin, 1.0 fiM dexamethasone, and 0.5 mM isobutylmethylxanthine (IBMX) for 48h. After this the medium was replaced by DMEM containing 10^g/ml insulin and incubated for 3 days. Then the differentiating cells were treated separately with l0µg/ml of enriched demethylated curcuminoids or methanol extracts of Moringa oleifera leaf or Murraya koenigii leaf separately or their compositions and maintained in the medium for another 3-5 days. The cells incubated with 0.1% DMSO were considered as the vehicle control. After the incubation period, cells were washed with phosphate buffered, saline (PBS) and fixed with 10% buffered formalin for In at room temperature. Qne small aliquot of cell suspension was separated for cell counting in hemocytometer chamber. Fixed cells were stained with Oil Red O solution to measure the cellular neutral lipid accumulation. Briefly, cells were washed with PBS, fixed with 10% buffered formalin and stained with Oil Red O solution (0.5 g in 100 ml isopropanol) for l0min. After removing the staining solution, the dye retained in the cells was eluted using isopropanol and OD was measured
at 550 nm. The inhibition of fat accumulation in the treated cells was compared with the mock treated differentiated adipocytes, The treated cells, and the control cells were also analyzed and compared for inhibition of lipid accumulation visually under microscope and recorded digitally in suitable image capture system. The % inhibition of lipid accumulation exhibited by enriched demethylated curcuminoids, methanol extracts of Moringa oleifera leaf and Murraya koenigii leaf or their compositions is summarized in table 1.

*The higher the % inhibition values, the higher the activity.

Protective effect of composition-1 (A combination of unit doses of demethylated curcuminoids 95% and methanol extracts of Moringa oleifera leaf and Murraya koenigii leaf in the ratio of 1: 12:7) against diet induced obesity in rats:
Selected healthy Sprague-Dawley rats were randomly assigned to control or various treatment groups (n=6). All the animals allocated for protective phase of the study were on dietary intervention by feeding high fat diet ad libitum and the animals allocated to treatment groups were simultaneously given oral administration of 250 mg/kg of composition-1 or 7 mg/kg sibutramine per day in 10 ml of 0.5% CMC, using gastric tube for the entire 8 week study duration. The test animals of the control group were simultaneously given l0ml/kg of 0.5% CMC. Food and water consumption were recorded daily, body weights were recorded weekly and fasting blood samples were collected before initiation, after 4* week and 8* week (termination) of the study. The treatment groups supplemented with 250 mg/kg of composition-! showed 21.5% reduction respectively in weight gain, against diet induced obesity, when compared with untreated control group (figure 1). The sibutramine supplemented treatment group showed 28.2% reduction in weight gain. The animals of the treatment group also showed significant reductions in serum triglycerides and lipid profile (anti-hyperiipidemic activity).

Example 8
Anti-obese activity of composition 1 in diet induced obese rats:
Selected healthy Spragu.e-Dawley rats were randomly assigned to control or various treatment groups (n=6). All the animals allocated for the study were made obese through dietary intervention by feeding high fat diet ad libitum for 8 weeks. After 8 weeks, the treatment groups of animals were given oral administration of 250 mg/kg of composition-1 per day in 10 mL of 0.5% CMC, using gastric tube for 8 week study duration. The animals of control group were given l0ml/kg of 0.5% CMC. Food and water consumption were recorded daily, body weights were recorded weekly and fasting blood samples were collected before initiation, after 4* week and 8* week (termination) of the study. The reduction in mean body weight gain of animals in treatment group supplemented with 250 mg/kg of composition-! is 13.2%, compared to those in the untreated control group (figure 2). The treatment group of animals also showed significant reduction in serum triglycerides and lipid profile (anti-hyperiipidemic activity).

Example 9
Effect of composition 1 on serum leptin concentration in diet induced obese animals during the protective efficacy and treatment efficacy evaluation studies and comparison with leptin level of control group of animals:
Serum leptin concentration was quantitatively measured by a sandwich ELISA. The assay procedure was based on the instructions provided by the vendor (Linco Research, USA). The serum samples collected from treatment group of animals supplemented with composition 1 (example #s 7 and 8) and control group were selected and subjected to leptin analysis. Leptin present in the treatment group and control group rat serum samples was bound on the antiserum coated 96-well micro-titer plate. Biotinylated detection antibody was allowed to bind with the immobilized leptin and thereafter, horseradish peroxides enzyme was incubated to bind with the biotinylated conjugates. After washing away of the free enzyme the specifically bound enzyme activity was detected in presence of the substrate 3,3',5,5'-tetramethylbenzidene. The enzyme activity was measured spectrophotometrically at 450 nm. The concentration of leptin in the rat serum was measured by interpolation from a reference curve generated with the reference standards of known concentrations of rat leptin. The sensitivity of this assay is 0.04 ng/ml of leptin.in rat serum. The mean serum leptin leVels for different treatment groups supplemented with composition 1 (250 mg/kg dose, example # 7) for protection against diet induced obesity and control (placebo) group are summarized in figure 3A. The mean serum leptin levels for treatment group supplemented with composition 1 (250 mg/kg dose, example # 8) for treatment against diet induced obesity, and that of control group are summarized in figure 3B.
