Description:
FIELD OF THE INVENTION 
       [0001]    The present invention relates to an Ayurvedic formulation containing hydro-alcoholic extract of  Berberis aristata, Trigonella foenum - graecum  and  Salacia parviflora  effective in decreasing the neopterin concentration thus beneficial in the prevention and management of neuro-vascular complications among type-2 diabetes cases. The present invention may be more advantageous if used in the prevention and management of neuro-vascular inflammation, oxidative injury, dyslipidemia including atherosclerosis and glycemic control in type-2 diabetes patients. The test substance has shown its major therapeutic activity in the prevention of diabetic neuro-vascular complications through its neopterin reducing property as well as its beneficial effect through acting on oxidative stress markers. 
       BACKGROUND OF THE INVENTION 
       [0002]    Neopterin in a product produced by human monocyte-derived macrophages and dendritic cells and is produced in excess amount when neopterin derivatives are upon stimulation with interferon-γ (IFN-γ). In this process neopterin derivatives are able to interfere with reactive oxygen, chlorine and nitrogen species and neopterin itself contributes to oxidative stress. Higher level of neopterin levels and oxidative stress markers are reported in neuro-vascular complications associated with different disease conditions. In neurodegeneration process neopterin concentrations in serum and cerebro-spinal fluid is correlated with the cognitive decline in patients. A significant increase of neopterin concentrations with age is reported in earlier studies. A higher concentration of neopterin with neurodegenerative disorders is perhaps due to immune activation mainly in elderly population. The studies have further supported the view that increased neopterin concentrations are associated with oxidative stress which could underlie an Increased demand of anti-oxidants in neurodegenerative conditions particularly in neurovascular complaints associated with diabetes where the oxidative stress play major role in their onset. An early identification of level of neopterin in diabetic patients with neuro-vascular complications is of clinical use as observations are made by various markers that higher neopterin concentrations were associated with reduced residual life span. A positive correlation has been established between neopterin concentration and type-2 diabetes mellitus. In neurodegenerative diseases, neopterin concentrations are correlated with serum concentrations of peroxides and homocysteine among patients with dementia. In such patients the serum concentration of peroxides and homocysteine is recorded among patients with dementia. In such patients the serum concentration of peroxides and neopterin were increased compared to normal people. Further, there is positive correlation between age and concentrations of peroxides, neopterin and homocysteine. 
         [0003]    Interaction between neopterin and oxidative stress markers is reported by various markers. Promotion of oxidative stress is a fundamental principle of neopterin release in the process of vascular changes in hyperglycemic condition. Raised serum neopterin levels are found to be associated with severity of disease as well as mortality rate also. 
         [0004]    Further, neopterin and TNF-α have also interdependencies, thus TNF-α has been described to enhance the effect of IFN-γ on neopterin synthesis in monocyte-derived macrophages. Neopterin levels are also increased in atherosclerosis in human. Thus application of estimation of neopterin in various diseases provides significant information for prevention and management of disease including neuro-vascular damage associated with diabetes. 
         [0005]    Insulin resistance is a key feature of metabolic diseases and is defined as a state that requires more insulin to obtain the biological effects achieved by a lower amount of insulin in the normal state. Thus, any defects in the insulin signaling cascade can cause insulin resistance. Insulin stimulates a signaling network composed of a number of molecules, initiating the activation of insulin receptor tyrosine kinase and phosphorylation of the insulin receptor substrate (IRS) proteins (e.g., IRS-1 and IRS-2). Among several components of the network, the signaling axis of IRS proteins and PI3K, which activates downstream serine/threonine kinases including Akt, regulates most of the metabolic actions of insulin, such as suppression of hepatic glucose production and activation of glucose transport in muscle and adipocytes. It is known that this pathway is impaired at the multiple steps through alterations in the protein levels and activities of the signaling molecules, enzymes, and transcription factors in insulin resistance caused by obesity, a state of increased adiposity. 
         [0006]    Risk factors for development of diabetic complications: 
         [0007]    Impaired glucose tolerance (IGT) is significantly associated with a 6-10 fold increase in overall risk of progression to type-2 diabetes mellitus. Individuals with IGT have a greater frequency of cardiovascular risk factors like hypertension, dyslipidemia and obesity. Some of the common risk factors like greater duration of diabetes, hypertension, poor metabolic control, smoking, obesity and hyperlipidemia were more prone to develop diabetic complications. Type-2 diabetes mellitus increases the risk of adverse coronary events two-fold in men and four fold in women, due to presence of CHD risk factors. 
         [0008]    Further, altered homocysteine, neopterin, leptin, inflammatory bio-markers all are significantly associated with neuro-vascular complications among diabetic patients. The major cardiovascular risk factors affects the endothelium, promoting enhanced endothelial permeability, expression of inflammatory markers and upregulation of particular enzymes that produce oxygen-free radicals, which together lead to the development of a low-grade chronic inflammatory state in the arterial wall. This type of action is responsible for various vascular complications in type-2 diabetes mellitus. Similarly elevated levels of circulating inflammatory markers among type-2 diabetes mellitus are responsible for development of cognitive impairment including development of vascular disease. 
         [0009]    Various studies have demonstrated clear benefits of good glycemic control in preventing or retarding the vascular complications in diabetic patients. 
         [0010]    Recently, a number of anti-diabetic agents are available to control hyperglycemia but due to long-term/life-long consumption, their use is restricted because of the risk profile. However, no suitable remedial measure is available having activity in prevention and management of neurogenic vascular complications among diabetic patients which badly hampers the quality as well as span of life. The available anti-hyperglycemic drugs include insulin secretagogues (sulfonylureas or meglitinides), insulin sensitizers (metformin or thiazolidinediones) and inhibitors of carbohydrate absorption (a-glucosidase inhibitors) but their long term application causes gastrointestinal disturbances, renal and hepatic impairments, etc. Therefore, there is an urgent need of satisfactory therapeutic modalities free from side-effects. In Ayurveda, various pharmacologic and non-pharmacologic methods have been prescribed for the prevention and management of diabetes and associated complications. Under the scheme Ayurveda as well as other traditional systems of medicine several plant-based drugs have been advocated to manage hyperglycemia. 
         [0011]    Taking the lead from Ayurveda, a plant based formulation containing hydro-alcoholic extract of  Berberis aristata, Trigonella foenum - graecum  and  Salecia parvillora  in an effective doses determined by us in pre-clinical analysis have been developed and validated for its neopterin lowering property with the object to prevention and treatment of neuro-vascular complications among type-2 diabetes patients. The out come of this study has novelty, innovative and has acceptability for general population as earlier no such type of study is carried out. 
       OBJECT OF THE INVENTION 
       [0012]    An object of present invention is to propose a plant based drug having neopterin lowering property through which diabetic neuro-vascular complications can be prevented and also the development of vascular complications can be delayed in diabetes patients. 
         [0013]    Another object of present invention is to propose a plant based drug showing better therapeutic potential in neuro-protection in diabetes patients. 
         [0014]    Further, object is to develop a plant based drug that can inhibit fat mobilizing enzymes and can enhance lipolysis in hyperglycemic condition. 
         [0015]    Yet another object of present invention is to propose an Ayurvedic formulation exerting anti-oxidant activity among type-2 diabetes patients. 
         [0016]    Still another object of present study is to propose a plant based drug showing anti-inflammatory role by reducing IL-2. TNF-α and IFN-γ in diabetic cases as inflammation is a major feature in vascular biology of atheroscderosis causing atherothrombosis resulting in coronary artery disease. Thus an adverse coronary stroke can be prevented. 
         [0017]    Still further object of present invention is to propose a botanical formulation beneficial in the prevention and management of neurogenic dementialcognitive deficits among type-2 diabetes patients. 
         [0018]    The foregoing has outlined some of the pertinent objectives of the present invention. However, these objectives should not be construed to be merely illustrative of some of the more prominent features and applications of the intended interventions. Many more therapeutic potentials of the test substance can be achieved through this invention. As synergism also the test drug has immunomodulatory, regulating altered neuro-chemical markers and better neurologic effects.

     DETAILED DESCRIPTION OF THE INVENTION 
       [0024]    For the purpose of promoting an understanding of the principles of the invention, reference is now to be made to the embodiments illustrates and the specific language would be used to describe the same. It is nevertheless to be understood that no limitations of the scope of the invention is hereby intended, such alterations and further modifications in the illustrated bag and such further applications of the principles of the invention as illustrated therein being contemplated as would normally occur to one skilled in the art to which the invention relates. 
         [0025]    The hydro-alcoholic extract of three medicinal plant candidates  Berberis aristata, Trigonella foenum - graecum  and  Salacia parviflora  prepared using 70:30 ratio water and alcohol respectively has been utilized for the development of present Ayurvedic formulation. The water utilized for extraction was decontaminated for any type of bacterial or abnormal growth by using reverse osmosis plant. The active molecules present in plant extracts were separated and quantified by applying HPLC, HPTLC and NMR procedures. In order to establish the neopterin lowering property of test formulation a mechanism based pre-clinical documentation was prepared. The therapeutic potential of test drug was determined by conducting various experimental and clinical trials. 
         [0026]    The neopterin lowering property of test drug was determined on the basis of mode of action of plant extracts separately as well as in combined form along with various targets involved in vascular complications in diabetes cases. Similarly the beneficial role of test drug was also assessed mainly through its anti-oxidant activity, lipolysis and insulin sensitivity improving effects, anti-inflammatory and anti-atherosderotic activity of test formulation. Further, the synergistic effects of test drug were also evaluated. 
         [0027]    Before utilizing the test drug for human consumption the pre-clinical safety and efficacy profile of single plant candidate extract as well as in combined form was conducted following standard norms. The biological property of test formulation was validated in streptozotocin (STZ) induced diabetes animal model which also helped in evaluation of vascular complications caused due to diabetes. The effect of test drug was assessed on glucose levels, insulin level, glycosylated hemoglobin, and pro-inflammatory cytokines, and the most important bio-marker neopterin including various neuro-psychological assessments. The mechanism based study clearly indicated the neopterin decreasing potential of test formulation which exerted neuro-protective activity, better glycemic control, anti-atherosclerotic, anti-inflammatory, anti-oxidant effects in STZ induced diabetes among the animals. Further, its therapeutic activity has also been validated in neurogenic dementia and other cognitive deficits associated with diabetes mellitus. 
         [0028]    Extraction procedure/process adopted in the present study: 
         [0029]    The shade dried rhizome of  Berberis aristata , seeds of  Trigonella foenum - graecum  and roots of  Salacia parviflora  were separately utilized for obtaining their extract. The hydro-alcoholic extract of the plants were utilized to determine the presence of molecules/active compound in both the plant extracts. The molecular characterization of plant extracts were done through IR and NMR. 
         [0030]    The extraction was done at a specific temperature 70°-80° and the pH of the solution was maintained by 5-6. 
         [0031]    According to this invention there is provided a plant based Ayurvedic formulation showing efficacy in the prevention and management of diabetic neuro-vascular complications through its neopterin lowering property. The present test drug comprises of following three plant extract—

         [0037]    In human increased concentration of neopterin in circulation and also in urine has been assessed in various clinical conditions. The generated data support the view that higher neopterin concentration produces heavy reaction oxygen species causing more oxidative injury that requires more anti-oxidant therapeutic agents in neurodegenerative conditions particularly when associated with diabetic patients. A number of studies have indicated that the concentration of neopterin were found significantly higher in Alzheimer&#39;s disease patients showing low scores of mini-mental state examination. Further, a significant correlation was observed between level of neopterin and TNF-α, IL-2. A possible correlation is also noticed with severity of dementia and level of neopterin. This type of study appears to be much important and early detection of neopterin concentration among diabetic patients with dementia or other cognitive deficits will be helpful in launching prevention and management strategies. A better mental health can be achieved out of such studies. As reported aging is associated with immune system activation which may lead to the increased production of peroxides, the anti-oxidant and immuno-modulatory measure will definitely provide a better result in protection from neurodegeneration through increasing anti-oxidant vitamins and modifying the stimulation of Immuno-competent cells. The involved mechanism of action may be that neopterin derivatives are able to interfere with reactive oxygen, chlorine and nitrogen species and neopterin itself causing oxidative stress and the method which will reduce the neopterin concentration will prevent the cognitive decline particularly associated with diabetic patients by preventing oxidative injury and monitoring of cell-mediated immune response. Thus study conducted by us appears very Important that changes in neopterin content detected in blood stream of patients with diabetes with dementia or neuro-vascular involvement, suggests its pathogenesis is considered to be confined to the brain. Further, it is hypothesized that as age advances among diabetics, there will be more association with immune system activation, increased production of peroxides and such people will need heavy medication for the management of their complaints. Thus, present study providing newer remedial measure has proven its beneficial role on new bio-markers associated with diabetes causing neuro-vascular complications. 
         [0038]    The present test formulation has been prepared out of hydro-alcoholic extract of three plants i.e.  Berberis aristata, Trigonella foenum - graecum  and  Salacia parviflora  In effective doses. This novel formulation has been proven for its neopterin lowering property in diabetes condition with the object of prevention and treatment of vascular complications particularly neuro-vascular abnormalities in type-2 diabetes patients. 
         [0039]    As enough knowledge exists indicating the role of life-style modification in the management of diabetes but the role of residual confounding by unknown factors cannot be eliminated/ignored. It is observed that there is close association between neopterin along with inflammatory markers IL-2 and TNF-α is responsible for vascular damage among diabetes patients. The test formulation was found beneficial in reducing IL-2, TNF-α and also the CRP in type-2 diabetes patients. It is pointed out that inflammation is a major feature in the vascular biology of atherosclerotic lesions. In all the stages i.e. fatty streak, plaque-rupture and thrombosis, inflammatory process play a pivotal role and link between inflammation and cardiovascular pathology/event and neurovascular changes is very strong. In the present study efforts have been made to prevent or delay the vascular complications through control of inflammatory process by decreasing the TNF-α, IL-2 and IFN-γ and decreasing neopterin level in diabetic patients.

       Clinical Evidence 
       [0092]    Results &amp; Observations: 
         [0093]    The clinical trial following test formulation in diabetes patients indicated significant improvement in neuropsychological as well as various biochemical parameters. At the initial level strong association between insulin resistance, type-2 diabetes mellitus and cognitive decline was observed. In other words a poor mental performance due to impairment in glucose metabolism has been noticed. A significant high concentration of serum neopterin was found to be associated with insulin resistance and cognitive function in diabetes patients. The test formulation exerted neuro-protective effects when evaluated on various neuropsychophysiological parameters in diabetes patients. Thus it is proven that some of the molecules or active constituents present in plant materials used in the test formulation has a role in preventing the neuro-toxic effects of glucose metabolism impairment and improved the cognitive function. It is concluded that test formulation has potentiality in preventing the neuro-vascular damage caused due to prolonged hyperglycemia.

       Example-I 
       [0094]    When the Hydro-alcoholic extract of  Berberis aristata  in the dose of 250 mg/kg b.w. was administered to STZ induced hyperglycemic rats showed reduction in neopterin concentration indicating better glycemic control than the non-treatment group of animals. The active compound present in plant extract berberin and palmitin showed potent anti-oxidant activity in βTC6 cells challenged with hydrogen peroxide. 
       Example-II 
       [0095]    When the hydro-alcoholic extract of  Berberis aristata  in the dose of 150 mg/kg b.w. and  Trigonella foenum - graecum  in the dose of 100 mg/kg b.w. given in combined form exerted significant increase in glutathione content and decrease in TBARS with important in other oxidative stress markers in comparison to disease control group. It prevented apoptosis and decreased insulin secreting cell population. The neuro-vascular damage was prevented through its anti-oxidant and anti-inflammatory activity. 
       Example-III 
       [0096]    When the hydro-alcoholic extract of  Berberis aristata  (60 mg/kg) and  Salacia parviflora  in the dose of 140 mg/kg b.w. was mixed and given to STZ induced hyperglycemic rats regulated carbohydrate metabolism by retaining glycogen content in the liver and muscle. Thus the carbohydrate metabolism with test substance is due to its potentiality to protect p-cell mass in the pancreas thereby improving plasma insulin level, improved glycemic index. 
       Example-IV 
       [0097]    When the hydro-alcoholic extract of  Berberis aristata  in the dose of 75 mg/kg b.w. and  Trigonella foenum - graecum  in the dose of 75 mg/kg b.w. to STZ treated diabetic rats have shown neopterin lowering activity and also reduced the glycosylated hemoglobin in hyperglycemic rats, thus has neuro-protective effects. 
       Example-V 
       [0098]    When the hydro-alcoholic extract of  Berberis aristata  in the dose of 75 mg/kg b.w.,  Salacia parviflora  in the dose of 75 mg/kg b.w. and  Trigonella foenum - graecum  in the dose of 50 mg/kg b.w. given in combined form to STZ induced diabetic rats exerted potential role in reducing neopterin concentration, improvement in altered oxidative stress markers and also showed neuro-protective effects by improving learning process (memory status) of the animals. 
         [0099]    In any combination of test substance prepared out of above three plants were found non-toxic on toxicological studies. 
       Example-VI 
       [0100]    After determination of safety profile of test formulation/single plant extract the test formulation was taken for human consumption to evaluate its beneficial role in the prevention and management of neuro-vascular complications in diabetes patients. The test formulation reduced the neopterin level of the diabetic patients exerting ability of test substance ( Berberis aristata  350 mg/day and  Salacia parviflora  425 mg/day) containing active bio-molecules exerted anti-oxidant property and improved cognitive function by enhancing memory, attention and overall mental performance in diabetes patients thus beneficial in the prevention and management of neurogenic dementia among diabetes patients. 
       Example-VII 
       [0101]    When the hydro-alcoholic extract of  Berberis aristata  in the dose of 375 mg/day and  Trigonella foenum - graecum  in the dose of 425 mg/day was given to diabetes patients showing cognitive impairment (poor memory and attention including behavioral abnormality) revealed reduced neuro-inflammation Indicating improved neuro-vascular degeneration caused due to hyperglycemia. 
       Example-VIII 
       [0102]    The test formulation has shown decrease in lipid accumulation when the hydro-alcoholic extract of  Berberis aristata  (450 mg/day) and  Salacia parviflora  (425 mg/day) was given to type-2 diabetes patients, reduced the neopterin level and elevated oxidative stress markers. This combination is having potentiality in reducing HbA1c and inflammatory markers IFN-γ, IL-2, and TNF-α in diabetic patients. 
       Example-IX 
       [0103]    The test formulation containing hydro-alcoholic extract of  Salacia parviflora  (375 mg/day) and  Trigonella foenum - graecum  (450 mg/day) containing active compounds has activity on cellular glucose consumption in pre-adipocyte cells and adipocytes as it accelerated glucose transpiring potency, decreased the neopterin level and increases the adiponectin concentration in diabetes patients. 
       Example-X 
       [0104]    When the hydro-alcoholic extract of  Berberis aristata  in the dose of 300 mg/day,  Trigonella foenum - graecum  in the dose of 250 mg/day and  Salacia parviflora  in the dose of 350 mg/day was administered to diagnosed patients of type-2 diabetes mellitus showed anti-hyperglycemic, anti-hyperlipidemic with amelioration of cognitive functions through its neopterin lowering activity and adiponectin enhancing effects among type-2 diabetes patients involving mechanism of mitigating oxidative stress, promoting insulin secretion, Inhibiting gluconeogenesis and glycogenolysis thereby regulating blood glucose in diabetic patients and preventing diabetic complications. The most important activity of present test formulation revealed that it regulated lipogenic markers like LPL, FAS and reduces neopterin level suggesting improved mental ability through improved neuro-vascular changes and improved atherogenic dyslipidemia among diabetes patients. The test substance contains numerous compounds mediating several activities prevented neuro-vascular complications through its anti-oxidant, anti-inflammatory and neopterin reducing effects among diabetes cases. Thus the use of present test formulation will be beneficial for the treatment of diabetes and its complications particular neuro-vascular changes rather than only its active anti-diabetic role. The study conducted by present team has generated scientific evidence for therapeutic uses of our traditional knowledge which supports our claims also. 
         [0105]    The test formulation exerted prevention/delayed development of vascular complications among type-2 diabetes patients through its neopterin lowering property. It improved the cognitive deficits particularly memory, attention and behavior complaints of diabetic patients as the test formulation is a potent anti-oxidant agent prevented neuron damage and enhanced neuronal plasticity among diabetic patients.
