1. Field of Invention
The field of the invention relates to products which may be administered to produce desirable physiological improvement. In particular, the invention relates to the administration of products enhanced with Morinda citrifolia in order to inhibit carbonic anhydrase, fatty acid amide hydrolase and endothelin-converting enzymes.
2. Background
Inhibition of Carbonic anhydrase is implicated in treatment for Glaucoma, seizures, epilepsy, paralysis, altitude sickness and kidney stone prevention. Carbonic anhydrase is a family of metalloenzymes that catalyze the rapid interconversion of carbon dioxide and water into carbonic acid, protons, and bicarbonate ions.
Some carbonic anhydrase inhibitors are commercially available. For example, Acetazolamide, sold under the trade name Diamox®, is a carbonic anhydrase inhibitor that is used to treat glaucoma, epileptic seizures, benign intracranial hypertension, altitude sickness, cystinuria, and dural ectasia. Acetazolamide is used in the treatment of various diseases. For glaucoma sufferers, the drug decreases fluid formation in the eye resulting in lower intraocular pressure. In epilepsy, its main use is in absence seizures, with some benefit in other seizure syndromes. It is also used to decrease generation of cerebrospinal fluid in benign intracranial hypertension and has also shown efficacy in autosomal dominant hyperkalemic periodic paralysis. It has also been demonstrated in drug trials to relieve symptoms associated with dural ectasia in individuals with Marfan Syndrome.
Diabetic retinopathy is result of microvascular retinal changes. Hyperglycemia-induced pericyte death and thickening of the basement membrane lead to incompetence of the vascular walls. These damages change the formation of the blood-retinal barrier and also make retinal blood vessel become more permeable. Small blood vessels in the eye are especially vulnerable to poor blood sugar control resulting in an over accumulation of glucose and/or fructose which damages the tiny blood vessels in the retina.
During the initial stage, called nonproliferative diabetic retinopathy (NPDR), most people do not notice any changes in their vision. Some people develop a condition called macular edema. It occurs when the damaged blood vessels leak fluid and lipids onto the macula, the part of the retina that lets us see detail. The fluid makes the macula swell, which blurs vision. As the disease progresses, severe nonproliferative diabetic retinopathy enters an advanced, or proliferative, stage. The lack of oxygen in the retina causes fragile, new, blood vessels to grow along the retina and in the clear, gel-like vitreous humour that fills the inside of the eye. Without timely treatment, these new blood vessels can bleed, cloud vision, and destroy the retina. Fibrovascular proliferation can also cause retinal detachment. The new blood vessels can also grow into the angle of the anterior chamber of the eye and cause neovascular glaucoma.
There are three major treatments for diabetic retinopathy, which are very effective in reducing vision loss from this disease: laser surgery, injection of triamcinolone into the eye and vitrectomy. Although these treatments are very successful, they do not cure diabetic retinopathy. Additionally, caution should be exercised in treatment with laser surgery since it causes a loss of retinal tissue. It is often more prudent to inject triamcinolone. In some patients it results in a marked increase of vision, especially if there is an edema of the macula.
Because medical treatments for diabetic retinopathy, glaucoma, seizures, epilepsy, paralysis, altitude sickness and kidney stones are non-existent, expensive or may involve serious side effects, compositions containing natural products that would treat diabetic retinopathy and glaucoma are highly desirable.
Some embodiments relate to formulations for inhibiting carbonic anhydrase, fatty acid amide hydrolase, and/or treating diabetic retinopathy and glaucoma comprising processed Morinda citrifolia products and methods for administering such.
Some embodiments provide a method of treating various diseases and ailments, which comprise administering to said mammal a processed Morinda citrifolia product selected from a group consisting of: extract from the leaves of Morinda citrifolia, leaf hot water extract, processed Morinda citrifolia leaf ethanol extract, processed Morinda citrifolia leaf steam distillation extract, Morinda citrifolia fruit juice, Morinda citrifolia extract, Morinda citrifolia dietary fiber, Morinda citrifolia puree juice, Morinda citrifolia puree, Morinda citrifolia fruit juice concentrate, Morinda citrifolia puree juice concentrate, freeze concentrated Morinda citrifolia fruit juice, Morinda citrifolia seeds, Morinda citrifolia seed extracts, extracts from defatted Morinda citrifolia seeds and evaporated concentration of Morinda citrifolia fruit juice.
The foregoing and other features of the present invention will become more fully apparent from the accompanying drawings when considered in conjunction with the following description and appended claims. Although the drawings depict only typical embodiments of the invention and are thus, not to be deemed limiting of the invention's scope, the accompanying drawings help explain the invention in added detail.
Embodiments of the present invention feature methods and compositions for inhibiting carbonic anhydrase, fatty acid amide hydrolase and endothelin-converting enzymes comprising processed Morinda citrifolia products. It will be readily understood that the components of the present invention, as generally described herein, could be arranged and designed in a wide variety of different configurations. Thus, the following more detailed description of embodiments of the compositions and methods of the present invention is not intended to limit the scope of the invention, as claimed, but is merely representative of the presently preferred embodiments of the invention. The scope of the invention is, therefore, indicated by the appended claims rather than by the foregoing description. All changes that come within the meaning and range of equivalency of the claims are to be embraced within their scope. General Description of the Morinda citrifolia L. Plant The Indian Mulberry or Morinda citrifolia plant is known scientifically as Morinda Citrifolia L. The plant is native to Southeast Asia and has spread in early times to a vast area from India to eastern Polynesia. It grows randomly in the wild, and it has been cultivated in plantations and small individual growing plots. Although the fruit has been eaten by several nationalities as food, the most common use of the Morinda citrifolia plant has traditionally been as a red and yellow dye source.
Processing Morinda citrifolia Leaves
The leaves of the Morinda citrifolia plant are one possible component of the Morinda citrifolia plant that may be present in some compositions of the present invention. For example, some compositions comprise leaf extract and/or leaf juice as described further herein. Some compositions comprise a leaf serum that is comprised of both leaf extract and fruit juice obtained from the Morinda citrifolia plant. Some compositions of the present invention comprise leaf serum and/or various leaf extracts as incorporated into a nutraceutical product (“nutraceutical” herein referring to any product designed to improve the health of living organisms such as human beings or mammals).
In some embodiments of the present invention, the Morinda citrifolia leaf extracts are obtained using the following process. First, relatively dry leaves from the Morinda citrifolia L. plant are collected, cut into small pieces, and placed into a crushing device—preferably a hydraulic press—where the leaf pieces are crushed. In some embodiments, the crushed leaf pieces are then percolated with an alcohol such as ethanol, methanol, ethyl acetate, or other alcohol-based derivatives using methods known in the art. Next, in some embodiments, the alcohol and all alcohol-soluble ingredients are extracted from the crushed leaf pieces, leaving a leaf extract that is then reduced with heat to remove all the liquid therefrom. The resulting dry leaf extract will herein be referred to as the “primary leaf extract.”
In some embodiments, the primary leaf extract is subsequently pasteurized. The primary leaf extract may be pasteurized preferably at a temperature ranging from 70 to 80 degrees Celsius and for a period of time sufficient to destroy any objectionable organisms without major chemical alteration of the extract. Pasteurization may also be accomplished according to various radiation techniques or methods.
In some embodiments of the present invention, the pasteurized primary leaf extract is placed into a centrifuge decanter where it is centrifuged to remove or separate any remaining leaf juice therein from other materials, including chlorophyll. Once the centrifuge cycle is completed, the leaf extract is in a relatively purified state. This purified leaf extract is then pasteurized again in a similar manner as discussed above to obtain a purified primary leaf extract.
Preferably, the primary leaf extract, whether pasteurized and/or purified, is further fractionated into two individual fractions: a dry hexane fraction, and an aqueous methanol fraction. This is accomplished preferably in a gas chromatograph containing silicon dioxide and CH2Cl2-MeOH ingredients using methods well known in the art. In some embodiments of the present invention, the methanol fraction is further fractionated to obtain secondary methanol fractions. In some embodiments, the hexane fraction is further fractionated to obtain secondary hexane fractions.
One or more of the leaf extracts, including the primary leaf extract, the hexane fraction, methanol fraction, or any of the secondary hexane or methanol fractions may be combined with the fruit juice of the fruit of the Morinda citrifolia plant to obtain a leaf serum (the process of obtaining the fruit juice to be described further herein). In some embodiments, the leaf serum is packaged and frozen ready for shipment; in others, it is further incorporated into a nutraceutical product as explained herein.
Processing Morinda citrifolia Fruit
Some embodiments of the present invention include a composition comprising fruit juice of the Morinda citrifolia plant. In some embodiments the fruit may be processed in order to make it palatable for human consumption and included in the compositions of the present invention. Processed Morinda citrifolia fruit juice can be prepared by separating seeds and peels from the juice and pulp of a ripened Morinda citrifolia fruit; filtering the pulp from the juice; and packaging the juice. Alternatively, rather than packaging the juice, the juice can be immediately included as an ingredient in another product, frozen or pasteurized. In some embodiments of the present invention, the juice and pulp can be pureed into a homogenous blend to be mixed with other ingredients. Other processes include freeze drying the fruit and juice. The fruit and juice can be reconstituted during production of the final juice product. Still other processes may include air drying the fruit and juices prior to being masticated.
In a currently preferred process of producing Morinda citrifolia fruit juice, the fruit is either hand picked or picked by mechanical equipment. The fruit can be harvested when it is at least one inch (2-3 cm) and up to 12 inches (24-36 cm) in diameter. The fruit preferably has a color ranging from a dark green through a yellow-green up to a white color, and gradations of color in between. The fruit is thoroughly cleaned after harvesting and before any processing occurs.
The fruit is allowed to ripen or age from 0 to 14 days, but preferably for 2 to 3 days. The fruit is ripened or aged by being placed on equipment so that the fruit does not contact the ground. The fruit is preferably covered with a cloth or netting material during aging, but the fruit can be aged without being covered. When ready for further processing the fruit is light in color, such as a light green, light yellow, white or translucent color. The fruit is inspected for spoilage or for excessive green color and firmness. Spoiled and hard green fruit is separated from the acceptable fruit.
The ripened and aged fruit is preferably placed in plastic lined containers for further processing and transport. The containers of aged fruit can be held from 0 to 30 days, but preferably the fruit containers are held for 7 to 14 days before processing. The containers can optionally be stored under refrigerated conditions prior to further processing. The fruit is unpacked from the storage containers and is processed through a manual or mechanical separator. The seeds and peel are separated from the juice and pulp.
The juice and pulp can be packaged into containers for storage and transport. Alternatively, the juice and pulp can be immediately processed into a finished juice product. The containers can be stored in refrigerated, frozen, or room temperature conditions. The Morinda citrifolia juice and pulp are preferably blended in a homogenous blend, after which they may be mixed with other ingredients, such as flavorings, sweeteners, nutritional ingredients, botanicals, and colorings. The finished juice product is preferably heated and pasteurized at a minimum temperature of 181° F. (83° C.) or higher up to 212° F. (100° C.). Another product manufactured is Morinda citrifolia puree and puree juice, in either concentrate or diluted form. Puree is essentially the pulp separated from the seeds and is different than the fruit juice product described herein.
The product is filled and sealed into a final container of plastic, glass, or another suitable material that can withstand the processing temperatures. The containers are maintained at the filling temperature or may be cooled rapidly and then placed in a shipping container. The shipping containers are preferably wrapped with a material and in a manner to maintain or control the temperature of the product in the final containers.
The juice and pulp may be further processed by separating the pulp from the juice through filtering equipment. The filtering equipment preferably consists of, but is not limited to, a centrifuge decanter, a screen filter with a size from 1 micron up to 2000 microns, more preferably less than 500 microns, a filter press, a reverse osmosis filtration device, and any other standard commercial filtration devices. The operating filter pressure preferably ranges from 0.1 psig up to about 1000 psig. The flow rate preferably ranges from 0.1 g.p.m. up to 1000 g.p.m., and more preferably between 5 and 50 g.p.m. The wet pulp is washed and filtered at least once and up to 10 times to remove any juice from the pulp. The resulting pulp extract typically has a fiber content of 10 to 40 percent by weight. The resulting pulp extract is preferably pasteurized at a temperature of 181° F. (83° C.) minimum and then packed in drums for further processing or made into a high fiber product.
Processing Morinda citrifolia Seeds
Some Morinda citrifolia compositions of the present invention include seeds from the Morinda citrifolia plant. In some embodiments of the present invention, Morinda citrifolia seeds are processed by pulverizing them into a seed powder in a laboratory mill. In some embodiments, the seed powder is left untreated. In some embodiments, the seed powder is further defatted by soaking and stirring the powder in hexane—preferably for 1 hour at room temperature (Drug:Hexane—Ratio 1:10). The residue, in some embodiments, is then filtered under vacuum, defatted again (preferably for 30 minutes under the same conditions), and filtered under vacuum again. The powder may be kept overnight in a fume hood in order to remove the residual hexane.
Still further, in some embodiments of the present invention, the defatted and/or untreated powder is extracted, preferably with ethanol 50% (m/m) for 24 hours at room temperature at a drug solvent ratio of 1:2.
Processing Morinda citrifolia Oil
Some embodiments of the present invention may comprise oil extracted from the Morinda Citrifolia plant. The method for extracting and processing the oil is described in U.S. patent application Ser. No. 09/384,785, filed on Aug. 27, 1999 and issued as U.S. Pat. No. 6,214,351 on Apr. 10, 2001, which is incorporated by reference herein. The Morinda citrifolia oil typically includes a mixture of several different fatty acids as triglycerides, such as palmitic, stearic, oleic, and linoleic fatty acids, and other fatty acids present in lesser quantities. In addition, the oil preferably includes an antioxidant to inhibit spoilage of the oil. Conventional food grade antioxidants are preferably used.

Morinda citrifolia puree juice or fruit juice may also be formulated with a processed Morinda citrifolia dietary fiber product present in similar concentrations.
The following example illustrates some of the embodiments of the present invention comprising the administration of a composition comprising components of the Indian Mulberry or Morinda citrifolia L. plant. These examples are not intended to be limiting in any way, but are merely illustrative of benefits, advantages, and remedial effects of some embodiments of the Morinda citrifolia compositions of the present invention.
As illustrated by the following Examples, embodiments of the present invention have been tested. Specifically, the Examples illustrates the results of in-vitro and in-vivo studies that confirmed that concentrates of processed Morinda citrifolia products (“TNJ” is an abbreviation for TAHITIAN NONI® Juice, “TNCONC” is an abbreviation for Tahitian Noni Freeze Concentrate, Sample 100 is an evaporative Noni concentrate, TNCMP1 is an abbreviation for Tahitian Noni Compound 1 Concentrates and is an evaporative Noni concentrate, Noni Puree is a Morinda citrifolia based puree produced as described in this invention and NLF3 is Noni leaf active fractions) could provide productive treatment for Glaucoma, seizures, epilepsy, paralysis, altitude sickness and kidney stone prevention. The percentage of concentration refers to the concentration strength of the particular concentrate tested; that is, the strength of concentration relative to the processed Morinda citrifolia product from which the concentrate was obtained.
In a preliminary experiment conducted TNJ and Compound 1 showed significant inhibition of Carbonic anhydrase. In particular a 1% solution of TNJ showed an 18% inhibition of Carbonic anhydrase while a 5% solution of TNJ showed a 75% inhibition of Carbonic anhydrase. Further, a 1% solution of compound 1 (noni concentrate) showed a 42% inhibition of Carbonic anhydrase, while a 5% solution of compound 1 demonstrated a 95% inhibition of Carbonic anhydrase.
In additional experiments conducted sample 100 and TNCMP1 showed significant inhibition of carbonic anhydrase as illustrated in the tables below and in
In additional experiments conducted sample 100 and TNCMP1 showed significant inhibition of Fatty acid amide hydrolase (FAAH) as illustrated in the tables below and in
<1%
TNJ was administered clinically to test subjects with diabetic retinopathy, cataracts, eye allergies and other eye irritations. Observations from the clinical studies conducted in which patients administered TNJ showed that test subjects with diabetic retinopathy experienced a significant diminishing of proliferating of new blood vessels in the retina and a decrease in the amount of leakage observed from some of the blood vessels that were causing hemorrhaging in the same retina or in the macula area. Additionally, it was noted that regular consumption of TJN decreased macula hemorrhaging over time. As a consequence test subjects with diabetic retinopathy subjectively reported experiencing a clearing of their previously blurry vision implicating the amelioration of existing cataracts. Moreover, TNJ showed positive results when used as eye-drops for allergies and other irritations of the eyes and eyelids.
The present invention may be embodied in other specific forms without departing from its spirit of essential characteristics. The described embodiments are to be considered in all respects only as illustrative and not restrictive. The scope of the invention is, therefore, indicated by the appended claims, rather than by the foregoing description. All changes that come within the meaning and range of equivalency of the claims are to be embraced within their scope.
