Description
Composition And Method For Increasing The Metabolism Of Free Fatty Acids And Facilitating A Favorable Blood Lipid Profile Related Applications This application is related to co-pending U.S., Patent Application:
, entitled "Composition for inducing lipolysis and increasing the metabolism of free fatty acids via increased nitric oxide levels" filed on May 11, 2007, the contents of which are hereby incorporated by reference in their entirety.
Field of the Invention The present invention relates to a dietary supplement for facilitating a more favorable blood lipid profile and increasing the metabolism of free fatty acids via increased nitric oxide levels. More specifically, the present invention relates to a dietary supplement comprising a combination of Cissus quadrangularis extract and y-butyrobetaine.
Background of the Invention Obesity, a condition of excessive body fat, generally results from more food being consumed than is being used. Stemming from excessive body fat, several health-related concerns have been linked to obesity and being overweight, such as increased morbidity, hypertension, coronary heart disease, type 2 diabetes mellitus, stroke and even some forms of cancer (Curioni C, Andre C, Veras R. Weight reduction for primary prevention of stroke in adults with overweight or obesity. Cochrane Database Syst Rev.
2006 Oct 18;(4):CD006062). Obesity has become an increasingly widespread and predominant health concern. According to the World Health Organization (WHO) obesity is considered a multifactorial chronic disease 7613335.2 which is increasing in frequency (Curioni C, Andre C, Veras R. Weight reduction for primary prevention of stroke in adults with overweight or obesity.
Cochrane Database Syst Rev. 2006 Oct 18;(4):CD006062).
One of the main contributing factors in obesity is overeating, which 30 results in an excess of energy being consumed in relation to the amount of energy being expended by an individual. This excess energy is then commonly stored as fat. A simplified determination of an individual's body weight is essentially governed by the net effect of energy consumed versus energy expended. Daily energy expenditure consists of three components:
35 basal metabolic rate, adaptive thermogenesis and physical activity (Westerterp KR. Diet induced thermogenesis. Nutr Metab (Lond). 2004 Aug 18;1(1):5). All of the aforementioned components must be in a balance with energy expenditure in an individual, that is, energy or food intake being such that an individual does not gain nor lose body weight. Therefore, in order for 40 a person to lose body weight from a reduction in adipose tissue, more energy must be expended by the individual than is taken into the body.
With the unprecedented rise in obesity throughout the world, there exists both a need and want from individuals for improved aids, methods and interventions directed to reducing body fat and maintaining lowered levels of 45 body fat. These needs have led to intensive study of the various mechanisms of fat metabolism. One such mechanism that has shown promise is the arginine-nitric oxide pathway. Nitric oxide (NO), which is synthesized from arginine by all cell types, has been shown to be a key signal molecule involved in adipose tissue biology by influencing adipogenesis and insulin-50 stimulated glucose uptake.
7613335.2 There are four major ways in which NO has been shown to influence energy metabolism. Firstly, NO has been shown to increase the phosphorylation of hormone-sensitive lipase and perilipin. Perilipin is a protein that coats lipid droplets in adipocytes and acts to protect triglycerides 55 from hormone-sensitive lipases, which break lipids into glycerol and free fatty acids. When the perilipin is phosphorylated it changes conformation and exposes stored lipids to hormone-sensitive lipase-mediated lipolysis, hence stimulation of lipolysis.
Second, NO has been shown to stimulate the phosphorylation of 60 adenosine-3',5'-monophosphate activated protein kinase. Activation of these kinases causes a decrease in levels of malonyl-CoA, which plays a key role in chain elongation in fatty acid biosynthesis by providing 2-carbon units to fatty acids thus comitting them to fatty acid chain synthesis. Additionally, activated kinases decrease the expression of genes related to lipogenesis and 65 gluconeogenesis. Thirdly, NO has been shown to increase blood flow to insulin-sensitive tissue, thus promoting substrate uptake and product removal.
Lastly, NO has been shown to activate the expression of peroxisome proliferator-activated receptors leading to enhanced mitochondrial biogenesis and oxidative phosphorylation.
70 Summary of the Invention The present invention is directed towards a dietary supplement, comprising at least a therapeutically effective amount of Cissus quadrangularis extract, and a therapeutically effective amount of y-butyrobetaine. The ingredients of the present dietary supplement act 75 substantially simultaneously to facilitate a more favorable blood lipid profile, 7613335.2 and increase the catabolism of free fatty acids via the phosphorylation of perilipins. Both a composition and a method are provided by the present disclosure.
Detailed Description of the Invention 80 In the following description, for the purposes of explanations, numerous specific details are set forth in order to provide a thorough understanding of the present invention. It will be apparent, however, to one of ordinary skill in the art that the present invention may be practiced without these specific details.
85 The present invention is directed towards a dietary supplement, for facilitating a more favorable blood lipid profile and increasing the catabolism of free fatty acids via the phosphorylation of perilipins, comprising a combination of Cissus quadrangularis extract and y-butyrobetaine. An aspect of the present invention comprises at least an extract of Cissus 90 quadrangularis and y-butyro beta i ne.
The term 'y-butyrobetaine' as used herein is understood to represent gamma-butyrobetaine, also known as, butyrobetaine, deoxycarnitine, actinine, 4-butyrobetaine, or 4-trimethylamniobutyrate. Additionally, as used herein, 'y-butyrobetaine' also includes derivatives of gamma-butyrobetaine such as 95 esters, amides, and salts, as well as other derivatives, including derivatives having pharmacoproperties upon metabolism to an active form.
The term 'more favorable blood lipid profile' as used herein is understood to represent and be characterized or influenced by any one or more of the following: a reduction in low-density lipoprotein (LDL), a reduction 7613335.2 100 in cholesterol, a lowering of fasting blood glucose levels, and increased levels of high-density lipoproteins (HDL).
Cissus quadrangularis Extract Cissus quadrangularis is a plant indigenous to India where it is part of traditional medicine. Extracts of Cissus quadrangularis contain sterols, 105 vitamin C, and tannins with antimicrobial in addition to antioxidant activity (Chidambara Murthy KN, Vanitha A, Mahadeva Swamy M, Ravishankar GA.
Antioxidant and antimicrobial activity of Cissus quadrangularis L. J Med Food, 2003. 6(2): p. 99-105). With respect to Cissus quadrangularis as a weight reduction agent, clinical studies have shown that a group taking an extract of 110 Cissus quadrangularis for 6-weeks lost more weight, had lower cholesterol, LDL and fasting blood glucose levels. The experimental group also displayed increased HDL levels as compared to a placebo group (Oben JE, Mandob D, Fomekong G, Momo C. The effect of an extract of Cissus quadrangularis (Cylaris TM) on weight and serum lipids in obese patients in Cameroon: a 115 randomized double-blind clinical trial. Presented at Paris Anti-Obesity Therapies. May 2006; Oben JE, Enyegue DM, Fomekong GI, Soukontoua YB, Agbor GA. The effect of Cissus quadrangularis (CQR-300) and a Cissus formulation (CORE) on obesity and obesity-induced oxidative stress. Lipids Health Dis. 2007 Feb 4;6:4). The lowering levels of LDL and raising levels of 120 HDL has been associated with improved health, particularly in conjunction with weight reduction (Dattilo AM, Kris-Etherton PM. Effects of weight reduction on blood lipids and lipoproteins: a meta-analysis: Am J Clin Nutr, 1992. 56(2): p. 320-8).
7613335.2 It is herein understood by the inventors that lowering levels of LDL and 125 cholesterol, as well as increasing levels of HDL will lead to a more favorable blood lipid profile, facilitating improved health via weight reduction.
An embodiment of the present invention comprises Cissus quadrangularis extract. A serving of the nutritional supplement contains from about 0.05 g to about 0.50 g of Cissus quadrangularis extract.
130 y-butyrobetaine (GBB) and Derivatives y-butyrobetaine is an intermediate in carnitine biosynthesis in mammals. It is synthesized, from trimethyl lysine, in almost all cell types and then excreted into the blood to be reabsorbed by the kidney and liver. After reabsorption, GBB is converted to carnitine by y-butyrobetaine dioxygenase.
135 This conversion to carnitine is extremely efficient and so the presence of y-butyrobetaine in urine is very small (Vaz FM, Wanders RJA. Carnitine biosynthesis in mammals. Biochem J. 2002;361:417-429).
Since y-butyrobetaine is a precursor to carnitine, its administration has been studied as a way to increase carnitine levels in the body. Carnitine acts 140 as a carrier molecule for fatty acids across the inner mitochondrial membrane.
In order for free fatty acids to be catabolized, they must first enter the mitochondria of a cell such that a-oxidation may take place to produce energy.
Fatty acids are first activated with the addition of coenzyme A(CoA), then bound to carnitine and transferred across the mitochondrial inner membrane, 145 after which the carnitine is removed.
As an additional effect, administration of y-butyrobetaine to rats (Sjakste N, Kleschyov JL, Baumane L, Dzintare M, Meirena D, Sjakste J, Sydow K, Munzel T, Kalvinsh I. Endothelium- and nitric oxide-dependent 7613335.2 vasorelaxing activities of gamma-butyrobetaine esters: possible link to the 150 antiischemic acitivites of mildronate. Eur J Pharmacol. 2004 Jul 8;
495(1):67-73 (Abstract)), showed elevated vasodilating activities. These vasodilating activities were attributed to increases in nitric oxide concentrations in blood.
Since nitric oxide has been shown to increase energy metabolism, it is herein understood by the inventors that increases in NO levels will lead to increased 155 catabolism of fatty acids, which will increase the utilization of adipocytes leading to reduced fat content in the body, by mechanisms that were previously discussed.
An embodiment of the present invention comprises y-butyrobetaine or derivatives thereof. A serving of the nutritional supplement contains from 160 about 0.005 g to about 0.050 g of y-butyrobetaine or derivatives thereof.
In an embodiment of the present invention, which is set forth in greater detail in Example 1, the dietary supplement comprises an extract of green tea, y-butyrobetaine, and y-butyrobetaine ethyl ester. The dietary supplement is provided in any acceptable and suitable oral dosage form as known in the art 165 to induce lipolysis and increase the metabolism of free fatty acids via increased nitric oxide levels.
While, not wishing to be bound by theory, the present invention is comprised of components that have been shown to reduce levels of LDL, cholesterol, and fasting blood glucose as well as increase levels of HDL. The 170 facilitation of a more favorable blood lipid profile will result in improved health via weight reduction (Dattilo AM, Kris-Etherton PM. Effects of weight reduction on blood lipids and lipoproteins: a meta-analysis. Am J Clin Nutr, 1992.
56(2):
p. 320-8).
7613335.2 Additionally, the present invention comprises components that have 175 been shown to lead to, via increased nitric oxide levels, increased phosphorylation of hormone-sensitive lipase and perilipin. It is herein understood by the inventors that increased phosphorylation of perilipin will result in greater likelihood of lipids being broken down by lipases, leading to increased release of free fatty acids.
180 Furthermore, increased nitric oxide levels will yield greater phosphorylation of adenosine-3',5'-monophosphate activated protein kinase, which will cause a decrease in levels of malonyl-CoA and decrease the expression of genes related to lipogenesis and gluconeogenesis. It is herein understood by the inventors that decreased malonyl-CoA will result in reduced 185 chain elongation of fatty acids and thus a decrease in fatty acid biosynthesis.
In addition, the present invention comprises components that have been shown to lead to, via increased nitric oxide levels, elevated expression of peroxisome proliferator-activated receptors. It is herein understood by the inventors that increased expression of peroxisome proliferator-activated 190 receptors will enhance mitochondrial biogenesis and oxidative phosphorylation, resulting in elevated metabolism of free fatty acids.
Further to the aforementioned functions, the present invention comprises components that have been shown to lead to, via increased nitric oxide levels, elevated blood flow to insulin-sensitive tissue. It is herein 195 understood by the inventors that increased blood flow will promote substrate uptake and product removal, thus increasing the movement of free fatty acids throughout the body.
7613335.2 Additional embodiments of the present invention may also include portions of the composition as fine-milled ingredients. U.S. Non-Provisional 200 Patent Application 11/709,526 entitled "Method for Increasing the Rate and Consistency of Bioavailability of Supplemental Dietary Ingredients" filed Feb 21, 2007, which is herein fully incorporated by reference, discloses a method of increasing the rate of bioavailability following oral administration of components comprising supplemental dietary compositions by the process of 205 particle-milling.
