Description

CURCUMINOID CHLOROPHYLLIN (CHL) COMPOSITIONS AND METHODS OF PREPARATION AND USE This application claims priority from US Application No. 62/564,819 filed on 28 September 2017, the contents of which are to be taken as incorporated herein by this reference.
TECHNICAL FIELD This invention relates to the field of curcuminoids. In particular, the invention relates to water soluble curcuminoid compositions and methods for preparing water-soluble curcuminoid compositions.
BACKGROUND Curcumin is the major curcuminoid of the Indian curry spice turmeric. Curcuminoids provide the major yellow color pigment of turmeric, which is derived from the rhizome of the Curcuma longa linn plant and it has been traditionally used in the treatment of skin wounds, inflammation, tumors et al.
Although raw turmeric contains more than 100 components, its characteristic yellow color is derived from various curcuminoids. Curcuminoids have a chemical structure consisting of 2 aromatic rings joined by a 7-carbon chain with various substituents.
Curcumin (1,7bis (4-hydroxymethoxy phenyl)-1,6 heptadiene-3,5-dione) is a hydrophobic polyphenol derivative which is a potent antioxidant derived from the spice turmeric. Commercial “curcumin” is a mixture of diarylheptanoid compounds, that usually a combination of about 77% diferuloylmethane (i.e. curcumin), 17% demethoxycurcumin, and 6% of bisdemethoxycurcumin.
Curcuminoids are the primary active ingredients of Cucuma longa rhizome (the turmeric plant). These curcuminoids are often identified as curcumin 1 (diferuylmethane), curcumin 2 (demethoxycurcumin), curcumin 3 (didemethoxycurcumin) and cyclocurcumin (A. Goel and A.
B. Kunnumakkara, 2008). Curcumin 1 (diferuylmethane) is the most potent of the naturally occurring curcuminoids.
Curcuminoids are natural phenolic compounds that are responsible for the yellow color of turmeric. Curcumin exists in several tautomeric forms.
Curcuminoids are generally hydrophobic compounds thought to have a variety of therapeutic benefits (for example, anti-inflammatory, anti-oxidant, anti-cancerous activities). 2 However, their therapeutic use has been limited by their hydrophobicity which results in poor solubility and rapid elimination from the body (i.e. low bioavailability).
While the poor bioavailability of curcumin is attributable to its poor absorption in the body, it is also quickly metabolized and rapidly eliminated from the body.
Curcuminoids have been shown to have potent activity against pancreatic cancer, to inhibit gastrointestinal carcinogenesis, and to protect against oxidative stress. It is also reported to have chemopreventative, chemotherapeutic, chemosensitizing, and radio-protective in normal cells and radiosensitizing in cancer cells. Curcumin has been reported to exhibit antitumor and anti-apoptotic properties and to suppress the growth of a variety of cancer cell lines in the laboratory and prevent the appearance of cancers in animal studies (Araujo and Leon, 2001).
In order to overcome the poor bioavailability of curcuminoid compounds, various efforts have been made to increase their bioavailability through complexing with cyclodextrins, micelles and nanoparticles.
Curcumin has chemo preventive, anti-neoplastic and anti-inflammatory properties in preclinical animal models (Gary J. Kelloff New Agents for Cancer Chemoprevention Journal of Cell Biochemistry (1996) 63 Supplement S26:1–28).
S.K Kulkarni demonstrate a role for curcumin in enhancing neurogenesis, notably in the frontal cortex and hippocampal regions of the brain (“Potentials of Curcumin as an Antidepressant” Scientific World Journal (2009) 9:1233–1241).
The synthesis and physiochemical characterization of a polymer based nanoparticle of curcumin called ‘nanocurcumin’ with less than 100 nm particle size was described by Savita Bisht et al. (“Polymeric nanoparticle-encapsulated curcumin (“nanocurcumin”): a novel strategy for human cancer therapy Journal of Nanobiotechnology (2007)5:3). The nanocurcumin was found to have similar in vitro activity as that of free curcumin in pancreatic cell lines.
WO2013175507 titled “Novel highly bioavailable, water soluble and sustained release nano-formulations of hydrophobic plant derived compounds and extracts” describes a nanoemulsified composition to enhance bioavailability of curcuminoids. The concentration of the emulsifier phase in the nanoformulations ranges from 60% to 95%. In addition, the application describes the use of emulsifiers which are anionic, cationic or non-ionic selected from but not limited to Polysorbates preferably Polysorbate 80 and Polysorbate 20, Polyethylene glycols preferably Polyethylene glycol 200 and Polyethylene glycol 400, Polyethylene glycol esters and Glycerol esters and also tabulates a series of composition of nanoformulations using hydrophobic compounds and also disclosed a process of pre-heating the emulsifier phase to a 3 temperature below the melting point of the hydrophobic active ingredient. Analytical results for the particle size of CurQlife (curcumin), morphological characteristics of CurQlife are provided, along with an aqueous phase curcumin concentration ranging from 5 to 20%. Furthermore, the maximum curcumin concentration achieved in human pharmacokinetic study was about 25ng/mL.
US patent 7,883,728 titled “Composition to enhance the bioavailability of curcumin” provides a method to improve bioavailability of curcumin preparation of a composition containing purified curcuminoid and purified oil and discloses a methodology to prepare a composition for enhanced bioavailability. The composition comprises a curcuminoid mixture consisting of demethoxycurcumin and bisdemethoxycurcumin and the essential oil arturmerone. The percent ratios of the composition consist of a range of 24% to 96% of curcuminoids combined with a range of 4% to 50% of the essential oil. The bioavailability of curcumin in human was shown to reach a maximum of about 93 ng/g.
WO2012024405 titled “Curcumin compositions and uses thereof” describes a composition and a method of increasing the bioavailability of curcumin. The composition is suitable for modifying DNA methylation and for treatment of cancer. The composition comprises curcumin and excipient polymers like polyethoxylated castor oil, polyoxyethylenesorbitan ester and polyethylene glycol. The application described the increased bioavailability of curcumin by using gel formulation and the formulation is safe, tolerated and effective in treatment of leukemia and breast cancer. The plasma level of curcumin was high in human volunteers thus increasing the bioavailability of curcumin. However, the invention is silent with respect to the absorption of curcumin from blood and its dispersibility, which affects the bioavailability.

The term “curcuminoid” as used herein, is meant to encompass a variety of linear diarylheptanoid compounds of natural and synthetic origins or even compounds of natural origin that are subsequently synthetically modified. A diarylheptanoid consists of two aromatic rings (aryl groups) joined by a seven carbons chain (heptane) or seven carbons forming a ring and linear linker (for example, see cyclocurcumin) and allowing for various substituents.
Common curcuminoids may include one or more of the following: curcumin; demethoxycurcumin; bisdemethoxycurcumin; cyclocurcumin; tetrahydrocurcumin; dihydrocurcumin; 12 curcumin-glucuronoside; dihydrocurcumin-glucuronoside; tetrahydrocurcumin-glucuronoside; curcuminsulphate; and hexahydrocurcumin.
The Indian spice turmeric, which is derived from the rhizome of the plant Curcuma longa, is a natural source of the curcumin. However, curcuminoids are found in many other plant families and the extracted curcuminoids may be modified to form curcuminoids derivatives. The most common curcuminoid derivatives are substituted on the phenyl groups, but may also have variations in the linking chain as shown above.
The term “chlorophyllin” (CHL) as used herein refers to a semi-synthetic food additive derived from chlorophyll, which may be extracted, for example, from alfalfa (Medicago sativa) or spinach (Spinacia oleracea), using any one or a combination of the solvents acetone, ethanol, 13 and hexane. The particular CHL (i.e. CAS Number: 110061) is determined by the identity of the cations associated with the anion. The most common form is a sodium/copper CHL derivative. Sodium copper CHL is a green to black powder prepared from chlorophyll by saponification and replacement of magnesium by copper. The structure of sodium copper CHL is: .
However, the sodium/magnesium CHL derivative is an alternative CHL. Similarly, sodium/zinc CHL derivative, chlorophyll paste or oil-soluble chlorophyll may be selected.
The term “green tea extract” as used herein is meant to encompass a tea extract from Camellia sinensis. For example, powdered decaffeinated green tea extract is available in numerous forms and purities from Millipore Sigma™ (i.e. CAS Number: 846502). The primary ingredient of which is epigallocatechin gallate (EGCG), is most abundant catechin in tea (i.e. for example, CAS Number 9895), which has the general structure .
The term “Rutin” or “rutoside” as used herein is refers to the glycoside combining the flavonol quercetin and the disaccharide rutinose (α-L-rhamnopyranosyl-(1→6)-β-Dglucopyranose). It is a citrus flavonoid found in wide variety of plants including citrus fruit. 14 .
The term “methylsulfonylmethane” (MSM) as used herein refers to an organosulfur compound with the formula (CH3)2SO2. MSM is also known by several other names including DMSO2, methyl sulfone, and dimethyl sulfone. The structure of MSM is .
The term “solubilization matrix” as used herein is meant to encompass a particular subset of solubilizers or a single solubilizer, in particular, wherein the solubilization matrix is selected from one or more of the following: (i) chlorophyllin (CHL); (ii) green tea extract; (iii) epigallocatechin gallate (EGCG); (iv) Rutin; (v) or combinations of any of (i)-(iv).
The terms "solubilizer" as used herein refers to a substance that improves the solubility of a curcuminoid in water.
The term "solubility" as used herein refers to the property of a solid, liquid, or gaseous chemical substance (“solute”) to dissolve in a solid, liquid, or gaseous solvent. The solubility of a substance fundamentally depends on the physical and chemical properties of the solute and solvent as well as on temperature, pressure and the pH of the solution.
The term “organic solvent” as used herein is refers to any solvent having at least 1 carbon atom and 1 hydrogen atom, a low molecular weight, lipophilicity, and volatility, and exist in liquid form at room temperature. Organic solvents may further be grouped as aliphatic or aromatic. Organic solvents are useful because they can dissolve oils, fats, resins, rubber, and plastics. An organic solvent may be selected from: methanol; ethanol; propanol; butanol; acetonitrile; and acetone.
Curcuminoids may be fully solubilized in chlorophyllin (CHL) at about 5% to about 70% by weight of a curcuminoid powder may be blended with a mixture of CHL and green tea extract or CHL alone. Alternatively, about 10% w/w to about 30% w/w of a curcuminoid powder may be blended with a mixture of CHL and green tea extract or CHL alone. A further alternative may include about 10% w/w to about 20% w/w of a curcuminoid powder is blended with a mixture of CHL and green tea extract or CHL alone. The content of CHL as a solubilizer may be from about 10% to about 95% by weight, or about 40% to about 80% by weight. The green tea extract used as a solubilizer may be from about 5% to about 90% by weight, or may be from about 20% to about 90% by weight, or may be from about 40% to about 90% by weight. The curcuminoid powder may be visually distinguishable in the chlorophyllin and green tea extract (if used) mixture as yellow particulates in the solution. However, when heat is applied (for example, until the solution reaches about 60-90°C or at about 80°C), the curcuminoid may become fully dissolved in chlorophyllin and green tea extract mixture as the particulates disappear and the solution turns to a transparent orange color. An organic solvent, or mixtures of solvents, including but not limited to methanol, ethanol, acetonitrile, acetone, propanol, and butanol may be added before or during the heating process and allowed to evaporate when heated. The solution of curcuminoid, chlorophyllin and green tea extract would then be allowed to cool to room temperature and return to solid form.
Solubility testing of the curcuminoid composition may proceeded as follows: 1 gram of curcuminoid composition added to 99mL of water, and shaken vigorously in order to mix; then about 3mL of solution is removed; then centrifuged at 6000*g for 5 minutes or, alternatively filtered through 0.2µm filter; the top layer of the centrifuged solution or the filtrate may be used for HPLC analysis; and the filtrate after 0.2µm filtration contains only water soluble curcumin particles smaller than 200nm.
Curcuminoids are fully solubilized in chlorophyllin (CHL) About 5% to about 70% by weight of a curcuminoids powder was blended with a mixture of chlorophyllin and green tea extract. Alternatively, about 10% w/w to about 30% w/w of a curcuminoids powder was blended with a mixture of chlorophyllin and green tea extract.
Alternatively, about 10% w/w to about 20% w/w of a curcuminoids powder was blended with a mixture of chlorophyllin and green tea extract. The content of chlorophyllin as a solubilizer may be from about 10% to 95% by weight, or most preferably from about 40% to about 80% by weight. The green tea extract used as a solubilizer may be from about 5% to about 90% by weight, or may be from about 20% to about 90% by weight, or may be from about 40% to about 90% by weight. At first, the curcuminoid powder is visually distinguishable in the chlorophyllin and green tea extract mixture as yellow particulates in the solution. However, when heat is applied to raise the solution temperature to about 60-90°C, or about 80°C, the curcuminoids become fully dissolved in chlorophyllin and green tea extract mixture as the particulates completely disappear and the solution turns to a transparent but orange color. An organic 16 solvent, or mixtures of solvents, including but not limited to methanol, ethanol, acetonitrile, acetone, propanol, and butanol may be added before or during the heating process and allowed to evaporate during the process. The solution of curcuminoids, chlorophyllin and green tea extract is then allows to cool to room temperature and return to solid form.

Existing commercial curcumin products (Reference #1 and #2 as described above) were compared against a curcumin and CHL composition using the same procedure with a wash out period of at least one week. The curcuminoid and CHL composition (TABLE 1) showed higher total plasma concentrations of curcumin than commercial curcumin products (see FIGURE 3B) and showed higher plasma concentrations over a longer time course than commercial curcumin products (see FIGURE 3A). The CHL water-soluble curcumin composition shows superior performance compared to other commercial compositions. The results described herein show that the curcuminoid CHL composition provides an improvement of at least 88% compared to other commercially available compositions.
EXAMPLE 3: HIGH PERFORMANCE LIQUID CHROMATOGRAPHY (HPLC) ANALYSIS OF CHL COMPOSITIONS WITH THREE ALTERNATIVE SOLUBILIZERS Human subjects were administered composition prepared comprising (1) curcuminoid and chlorophyllin (CHL) with green tea extract (GT); (2) curcuminoid and chlorophyllin (CHL) with methylsulfonylmethane (MSM); and (3) curcuminoid and chlorophyllin (CHL) with Rutin. 19 Furthermore, HPLC was used to compare three ratios of CHL to the second solubilizer (i.e. GT, MSM or Rutin (i.e. ratios of either 1:9, 2:8 and 3:7). Blood sampling and extraction was conducted as set out in FIGURE 2, prior to HPLC (High Performance Liquid Chromatography) analysis of the extract. As shown in FIGURE 4A and FIGURE 4B, CHL with GT was compared at three ratios (i.e. 1:9, 2:8 and 3:7). The highest concentrations of curcuminoid was found in compositions having higher CHL relative to GT (i.e. 3:7 ratio). Similarly, as shown in FIGURE 5A and FIGURE 5B, CHL with MSM was compared at three ratios (i.e. 1:9, 2:8 and 3:7). Although the total curcuminoid concentration was lower than in for CHL with GT, there was still a trend towards increased concentrations of curcuminoid in compositions having higher CHL relative to MSM (i.e. 2:8 and 3:7 ratio). Similar to the CHL with MSM, as shown in FIGURE 6A and FIGURE 6B, CHL with Rutin was compared at three ratios (i.e. 1:9, 2:8 and 3:7). Although the total curcuminoid concentration was lower than in for CHL with GT and CHL with MSM, there was still a trend towards increased concentrations of curcuminoid in compositions having higher CHL relative to Rutin (i.e. 2:8 and 3:7 ratio).
The use of CHL increases the amount of curcuminoid component present in the blood and plasma when compared to other commercially available curcumin products. Accordingly, the use of CHL has positive role the delivery of curcuminoids.
The optimal ratio of CHL and GT for maximum absorption of curcumin is 3:7.
Compared with other ratios tested, the composition with 3:7 ratio shows about 8 times the amount of curcumin.
