AI Technical Summary
Existing methods struggle to effectively induce the production of phase II detoxification enzymes, such as NQO1, to counteract the harmful effects of quinone estrogens, which are associated with conditions like breast cancer, due to variations in microbiota and acidic environments that hinder the conversion of sulforaphane precursors.
A composition comprising a sulforaphane precursor, an enzyme (like myrosinase) to convert it to sulforaphane, an enzyme enhancer (such as ascorbic acid), and mushroom extracts (like Maitake, Shiitake, or Reishi) to enhance the induction of NQO1 and counteract quinone estrogens.
The composition effectively increases NQO1 levels and gene expression, reducing cancer incidence and symptoms associated with elevated quinone estrogens by administering sulforaphane precursors, enzymes, and mushroom extracts.

[0002] The present invention relates to a combination of a sulforaphane precursor, an enzyme capable of converting the sulforaphane precursor to sulforaphane, an enzyme enhancer, and a mushroom (preferably, Maitake, Shiitake, or Reishi) extract or powder. The present invention also relates to a combination of sulforaphane or a derivative thereof and a mushroom (preferably, Maitake, Shiitake, or Reishi) extract or powder. The present invention also relates to a combination of a broccoli extract or powder and a mushroom (preferably, Maitake, Shiitake, or Reishi) extract or powder. The present invention provides compositions and methods related to these combinations. [Background technology]
[0003] The use of natural products is becoming increasingly popular for humans and companion animals. Some of these natural products are incorporated into dietary supplements and medical foods. There is a need in the art for dietary supplements that are useful as chemoprotective agents and / or antioxidants. Additionally, there is a need in the art for pharmaceutical compositions and dietary supplements that are useful for breast-related conditions and disorders.
[0004] Chemoprotection through the use of natural products is developing as a safe, effective, inexpensive, readily available, and practical means to prevent or reduce the occurrence of numerous conditions affecting humans and livestock. It has been found that carcinogens, which can damage cells at the molecular level, are often ingested and inhaled as non-toxic precursors. These non-toxic precursors can then be converted into carcinogens in the body. Chemoprotectants, such as natural substances that can activate detoxification enzymes or their cofactors, can counteract, allow elimination, or enhance other naturally occurring defenses, such as the immune system.
[0005] Some natural products have antioxidant activity. Oxidative stress plays a major role in aging, the progression of neurodegenerative diseases, and physiological trauma such as ischemia. Antioxidants can reduce or inhibit the oxidation of important biomolecules, and can play a role in treating, preventing, or reducing the occurrence of cancer, coronary heart disease, stroke, and neurodegenerative diseases, and Alzheimer's disease, dementia, and stroke are examples of conditions affected by oxidative stress.
[0006] Cancer is thought to be primarily the result of exposure to environmental insults, whether internal (i.e., estrogen, progesterone hormones) or external (i.e., bisphenol A (BPA) from plastics), and chronic inflammation. Fortunately, damage from environmental insults can be counteracted by a complex network of phase II chemoprotective enzymes found in numerous cell types throughout the body. It is well known that estrogen and its metabolites can lead to breast tissue and tumor growth. To make matters worse, quinone estrogen metabolites have the ability to invade breast tissue and migrate into the nuclei of ductal and glandular epithelial cells. There, they bind to DNA to form quinone estrogen-DNA adducts, leading to downstream mutations. These mutations are thought to be involved in cancer initiation, the very basis of tumor development. Fortunately, a specific phase II enzyme, NAD(P)H:quinone oxidoreductase (NQO1), can capture dangerous, highly reactive quinone estrogens and metabolize them into inactive chemicals that can be easily eliminated from the body. Therefore, the main mechanism for reducing cancer incidence is to induce protective phase II enzymes, including NQO1. Increasing the level of NQO1 can be effective in treating, preventing, repairing, reducing the occurrence and decreasing symptoms associated with any condition caused by high levels of quinone estrogens. Examples of quinone estrogens include, but are not limited to, estrogenic catechol quinones. Quinone estrogens are described in the following references, each of which is incorporated by reference in its entirety: Non-Patent Document 1; Non-Patent Document 2; Non-Patent Document 3; and Non-Patent Document 4.
[0007] One example of a natural product thought to have chemoprotective and antioxidant properties is sulforaphane. Sulforaphane is an organosulfur compound also known as 1-isothiocyanato-4-methylsulfinylbutane. The sulforaphane precursor, glucoraphanin, can be obtained from cruciferous vegetables such as broccoli, Brussels sprouts, and cabbage. However, to obtain levels adequate for chemoprevention, large amounts of vegetables must be consumed. Glucoraphanin is converted to sulforaphane by a thioglucosidase enzyme called myrosinase, which occurs endogenously in various exogenous sources, such as cruciferous vegetables, and in the gut microbiota. However, upon oral ingestion of glucoraphanin, not all animals are able to achieve its conversion to sulforaphane, most likely due to variations in the microbiota population and overall health. Furthermore, in acidic environments such as the stomach, glucoraphanin can be converted to inactive metabolites. The active metabolite, sulforaphane, induces nuclear erythroid-2-related factor (Nrf2), which then upregulates the production of phase II detoxification and cellular defense enzymes, such as glutathione S-transferase, NAD(P)H:quinone oxidoreductase (NQO1), and heme oxygenase-1 (HO-1). Sulforaphane is thought to induce the production of these enzymes without significantly altering the synthesis of P-450 cytochrome enzymes. Upregulation of phase II enzymes is thought to play a role in various vital processes, including protecting the brain from cytotoxicity, protecting the liver from the toxic effects of fat accumulation, and detoxifying various other tissues.
[0008] Sulforaphane and its precursor glucoraphanin have been widely studied. Shapiro et al. (Non-Patent Document 5) discuss a Phase I clinical study to determine the safety, tolerability, and metabolism of broccoli sprout glucosinolates and isothiocyanates. Shapiro et al. discuss a placebo-controlled, double-blind, randomized clinical trial of sprout extracts containing either glucosinolates such as glucoraphanin or isothiocyanates such as sulforaphane in healthy human subjects. The study found that administration of these substances did not result in systematic, clinically significant side effects. Ye et al. (Non-Patent Document 6) discuss the pharmacokinetics of broccoli sprout isiothiocyanates in humans.
[0009] Several mushrooms have been used or studied for their medicinal properties. These "medicinal mushrooms" are believed to have beneficial properties, such as antiviral, antimicrobial, anticancer, hypoglycemic, and / or anti-inflammatory activities. Examples of medicinal mushrooms include maitake, shiitake, reishi, cremini, almond, chestnut, wood ear, cloud ear, porcini, ink cap, yarta gunbu, enokitake, shimeji, tiger milk, morel, bamboo, tamogitake, pink oyster, king oyster mushroom, oyster mushroom, cauliflower, white wood ear, golden jelly, matsutake, Mexican truffle, and straw mushroom.
[0010] Maitake mushrooms (Grifola frondosa) are widely consumed as food and are used in traditional medicine to enhance immune function and treat cancer. Maitake mushrooms, which contain glucans, are believed to have beneficial properties, including antitumor and immunomodulatory effects. Standardized extracts derived from maitake mushrooms contain glucans, such as protein-linked β-glucans, as active ingredients. β1,6-glucan (a protein-linked polysaccharide) has been identified as the active ingredient in maitake mushrooms. Maitake mushrooms have been demonstrated to have antitumor effects, inhibiting tumor metastasis in vitro. In one study, tumor regression or significant symptom improvement was observed in half of the subjects using maitake extract. A study of postmenopausal breast cancer patients showed that oral administration of maitake extract had immunomodulatory effects.
[0011] Shiitake mushrooms (Lentinula edodes) are edible mushrooms native to East Asia. Shiitake mushrooms contain mycochemicals hypothesized to have antiviral, antibiotic, anti-inflammatory, antihypertensive, and anticarcinogenic effects. This is thought to be largely the result of glucans, both α- and β-glucans. Some shiitake mushroom extracts have an α-glucan content of over 40%. Furthermore, lentinan (1,3β-D-glucan, a polysaccharide isolated from shiitake mushrooms) has been well studied and is thought to play a role in shiitake's beneficial effects. It has been shown to have anticancer effects in colon cancer cells, which may be due to its ability to inhibit the cytochrome P450-1A enzyme, which is known to metabolize carcinogen precursors to their active forms. Lentin (its protein component) has potent antifungal properties, inhibits leukemia cell growth, and suppresses the activity of human immunodeficiency virus-1 reverse transcriptase.
[0012] Reishi mushroom (Ganoderma lucidum), also known as lingzki mushroom, is an edible mushroom found in East Asia. Reishi mushrooms are thought to have antitumor, anticancer, immunomodulatory, and immunotherapeutic effects. Reishi mushrooms possess several components that are thought to contribute to their activity, including glucans such as β-glucan, canthaxanthin, sterols, coumarin, ganoderic acid, and mannitol.
[0013] Baker's yeast (Saccaromyces cerevisiae) can be a source of glucans, particularly β-glucans. The active components of baker's yeast can be extracted by several methods, such as those described in Non-Patent Document 7, Patent Document 1, Patent Document 2, and Patent Document 3, each of which is incorporated by reference in its entirety.
[0014] Glucans are described in the following references, each of which is incorporated by reference in its entirety: Glucans, 1999, pp. 111-114, 1999; and 1999, pp. 111-114, 1999.
[0015] Zhang et al. (Non-Patent Document 10) discuss a study in Sprague-Dawley rats to determine the anticarcinogenic activity of sulforaphane and structurally related synthetic norbornyl isiothiocyanates. The study determined that administration of sulforaphane was effective in preventing the formation of mammary tumors.
[0016] Cornblatt et al. (Non-Patent Document 11) discuss a study in Sprague-Dawley rats to determine the effect of sulforaphane in chemoprevention in the breast. The study determined that oral administration of either sulforaphane resulted in a three-fold increase in NAD(P)H:quinone oxidoreductase (NQO1) enzyme activity and a four-fold increase in immunostaining for the heme oxygenase-1 (HO-1) enzyme in the mammary epithelium.
[0017] Munday et al. (Non-Patent Document 12) discuss a study on the effect of a freeze-dried aqueous extract of broccoli sprouts on bladder carcinogenesis in rats. The study found that administration of broccoli sprout extract resulted in significant induction of glutathione S-transferase and NAD(P)H:quinone oxidoreductase 1 in the bladder, enzymes with protective activity against oxidants and carcinogens.
[0018] Fang et al. (Non-Patent Document 13) disclosed a study to determine the antiproliferative effects of the ethyl acetate fraction of Lentinula edodes mushroom on human breast carcinoma cell lines (MDA-MB-453 and MCF-7), a human non-malignant breast epithelial cell line (MCF-10F), and two myeloma cell lines (RPMI08226 and IM-9). The study found that the inhibition of tumor cell growth by components in Lentinula edodes mushroom could be attributed to the induction of apoptosis.
[0019] Kim et al. (Non-Patent Document 14) have disclosed a study investigating the natural killer (NK) cell activation and anti-cancer effects of rice bran-derived exobiopolymers cultured from shiitake mushrooms (Lentinus edodes). This study found that exobiopolymers may be effective for the prevention and / or treatment of cancer through natural killer cell activation.
[0020] Louie et al. (Non-Patent Document 15) discuss the synergistic effect of a combination of interferon-α and Maitake mushroom D-fraction (PDF, a bioactive mushroom extract) on the anticancer activity of interferon-α in bladder cancer T24 cells in vitro.
[0021] Masuda et al. (Non-Patent Document 16) discuss a study evaluating the anti-metastatic activity of a fraction of Maitake mushroom in a mouse model of lung metastasis. The study found that the fraction inhibited tumor metastasis by inhibiting tumor cell adhesion to vascular endothelial cells through activation of natural killer cells and antigen-presenting cells (APCs) and suppression of adhesion molecules such as ICAM-1.
[0022] Patent Document 4 discloses a formulation containing an encapsulated or coated glucosinolate such as glucoraphanin and myrosinase.

[0061] In some embodiments, the ratio of β-glucan to sulforaphane or its derivative (β-glucan:sulforaphane or its derivative) is about 50:1 to about 1:50, preferably about 25:1 to about 1:25, more preferably about 10:1 to about 1:20, more preferably about 5:1 to about 1:10, even more preferably about 1:1 to about 1:8, and most preferably about 1:3 to about 1:5. In some embodiments, the ratio of α-glucan to sulforaphane or its derivative (α-glucan:sulforaphane or its derivative) is about 1:50 to about 50:1, preferably about 1:10 to about 25:1, more preferably about 1:5 to about 20:1, more preferably about 1:1 to about 15:1, even more preferably about 2:1 to about 10:1, and most preferably about 3:1 to about 8:1.

[0062] In some embodiments, the composition comprises a unit dosage form, including but not limited to, pharmaceutical dosage forms suitable for oral, rectal, intravenous, subcutaneous, intramuscular, transdermal, transmucosal, and topical administration. In some preferred embodiments, the composition comprises an orally administrable dosage form or a rectally administrable dosage form. Examples of orally administrable dosage forms include, but are not limited to, tablets, capsules, powders dispersible in beverages, liquids such as solutions, suspensions, or emulsions, soft gels / chewable capsules, chewable bars, or other convenient dosage forms known in the art. In preferred embodiments, the composition comprises a tablet, capsule, or soft chewable treat. Orally administrable dosage forms can be formulated for immediate release, sustained release, or delayed release.
[0063] In some embodiments, at least the sulforaphane precursor, enzyme, and enzyme enhancer are provided in a dosage form that allows for release in a region of the gastrointestinal tract having a pH of at least 4, preferably at least 5, e.g., the small intestine, preferably the duodenum. In some embodiments, at least sulforaphane or a derivative thereof and / or broccoli extract or powder are provided in a dosage form that allows for release in a region of the gastrointestinal tract having a pH of at least 4, preferably at least 5, e.g., the small intestine, preferably the duodenum. In some embodiments, the mushroom extract or powder and / or any optional additional components are also released in a region of the gastrointestinal tract having a pH of at least 4, preferably at least 5, e.g., the small intestine, preferably the duodenum. The small intestine includes the duodenum, jejunum, and ileum.
[0064] In some embodiments, each of these components (i.e., sulforaphane precursor, enzyme, enzyme enhancer, sulforaphane or a derivative thereof, broccoli extract or powder, mushroom extract or powder, and / or additional components) is released simultaneously or concomitantly (i.e., within a short period of each other). This provides an advantage over glucoraphanin-containing compositions formulated to release glucoraphanin in regions of the gastrointestinal tract having a pH below 4, e.g., the stomach. In such low pH environments, the acidic environment may result in conversion of the sulforaphane precursor to other physiologically inactive end-products, e.g., sulforaphane nitrile and epithionitrile.
[0065] In some embodiments, the composition may comprise an orally administrable composition comprising an enteric-coated dosage form or any dosage form that is resistant to degradation in regions of the gastrointestinal tract with a pH of less than 4, such as the stomach. For example, the orally administrable composition may comprise a tablet or capsule containing an enteric coating. The enteric coating may comprise materials including, but not limited to, cellulose acetate phthalate, hydroxypropylmethylcellulose phthalate, polyvinyl acetate phthalate, methacrylic acid copolymer, methacrylic acid:acrylic acid ester copolymer, hydroxypropylmethylcellulose acetate succinate, hydroxypropylmethylcellulose trimellitate, shellac, cellulose acetate trimellitate, carboxymethylethylcellulose, and mixtures thereof. The enteric coating may comprise any suitable enteric polymer known in the art. In some embodiments, one or more of the components in the composition may be embedded in a matrix of an enteric polymer. In some embodiments, the orally administrable composition comprises a capsule that dissolves slowly in stomach acid and travels to the small intestine, such as DRCAPS™ acid-resistant capsules marketed by CAPSUGEL® or any other acid-resistant capsule.
[0066] In the most preferred form, the orally administrable composition is surrounded by a coating that will not dissolve unless the surrounding medium has a pH of at least 4, more preferably at least 5. Alternatively, a coating that controls release by time rather than pH can be used, with the rate adjusted so that the ingredient is not released until after the pH of the gastrointestinal tract has risen to at least 4, more preferably at least 5. Thus, sustained-release formulations can be used to prevent the presence of sulforaphane precursors, enzymes and enzyme enhancers capable of converting sulforaphane precursors to sulforaphane, or sulforaphane itself in the stomach. Using standard coating techniques, a coating layer(s) can be applied to the orally administrable composition. Enteric coating materials can be dissolved or dispersed in organic or aqueous solvents. The pH at which the enteric coat dissolves can be controlled by the selected polymer or polymer combination and / or the ratio of pendant groups. For example, the dissolution characteristics of a polymer film can be altered by the ratio of free carboxyl groups to ester groups. The enteric coating layer also contains a pharmaceutically acceptable plasticizer such as triethyl citrate, dibutyl phthalate, triacetin, polyethylene glycol, polysorbate, or other plasticizer. Additives such as dispersants, colorants, anti-adherents, and anti-foaming agents may also be included.
[0067] The composition may contain one or more non-active pharmaceutical ingredients (also commonly known as "excipients"). Non-active ingredients serve, for example, to solubilize, suspend, thicken, dilute, emulsify, stabilize, preserve, protect, color, flavor, and shape the active ingredient into a safe, convenient, otherwise acceptable, applicable, and effective preparation for use. Preferably, the excipient is a pharmaceutically acceptable excipient. Examples of classes of pharmaceutically acceptable excipients include lubricants, buffers, stabilizers, foaming agents, dyes, colorants, flavorings, fillers, bulking agents, fragrances, release-modifying agents, adjuvants, plasticizers, glidants, mold release agents, polyols, granulating agents, diluents, binders, buffers, absorbents, glidants, adhesives, anti-adherents, acidulants, emollients, resins, demulcents, solvents, surfactants, emulsifiers, elastomers, and mixtures thereof.
[0068] In some embodiments, the combination of (i) a sulforaphane precursor, preferably glucoraphanin, (ii) an enzyme capable of converting the sulforaphane precursor to sulforaphane, preferably a glucosidase enzyme, more preferably a thioglucosidase enzyme, and most preferably myrosinase, (iii) an enzyme enhancer, preferably an enzyme cofactor, more preferably ascorbic acid, and (iv) a mushroom extract or powder (containing glucan) exhibits synergistic effects. In some embodiments, the combination of sulforaphane (or a derivative thereof) and a mushroom extract or powder (containing glucan) exhibits a synergistic effect. Synergy refers to the effect of a combination of two or more ingredients providing a result that is greater than the sum of the effects provided by the substances when used alone. In preferred embodiments, the synergistic effect is greater than an additive effect. In some embodiments, the combination of a sulforaphane precursor, an enzyme capable of converting the sulforaphane precursor to sulforaphane, an enzyme enhancer, and a Maitake, Shiitake, or Reishi mushroom extract or powder has a statistically significantly greater effect than (i) each component alone, (ii) the combination of the sulforaphane precursor and enzyme alone, and / or (iii) the combination of the sulforaphane precursor, enzyme, and enzyme enhancer alone.
[0069] In preferred embodiments, the combination of sulforaphane precursor, enzyme, enzyme enhancer, and mushroom extract or powder (containing glucan) exhibits synergy by having a statistically significant and / or greater than additive effect compared to the sulforaphane precursor alone and the mushroom extract or powder alone. In some embodiments, the combination of glucoraphanin, myrosinase, ascorbic acid, and mushroom extract or powder has a synergistic effect compared to the combination of glucoraphanin, myrosinase, and ascorbic acid alone, and compared to glucan alone.
[0070] In some embodiments, the combination of sulforaphane (or a derivative thereof) and mushroom extract or powder has a statistically significant and / or greater than additive effect than (i) sulforaphane (or a derivative thereof) alone and / or (ii) mushroom extract or powder alone. In some embodiments, the combination of sulforaphane and glucan has a synergistic effect compared to sulforaphane alone and glucan alone.
[0071] In some embodiments, the combination of broccoli extract or powder and mushroom extract or powder has a statistically significant and / or greater than additive effect than (i) broccoli extract or powder alone and / or (ii) mushroom extract or powder alone. In some embodiments, the combination of broccoli extract or powder and glucan has a synergistic effect compared to broccoli extract or powder alone and glucan alone.

[0082] formulation
[0083] The following are exemplary formulations of the present invention.
[0084] Formulation A Broccoli seed extract containing glucoraphanin (approximately 12% by weight), 50 mg to 5 grams, freeze-dried broccoli sprout powder containing myrosinase, 25 mg to 500 mg, ascorbic acid, 1 mg to 50 mg, shiitake mushroom extract containing alpha-glucan (approximately 40% by weight), 1 mg to 250 mg
[0085] Formulation B Broccoli seed extract containing glucoraphanin (approximately 12% by weight), 50 mg to 5 grams, freeze-dried broccoli sprout powder containing myrosinase, 25 mg to 500 mg, ascorbic acid, 1 mg to 50 mg, maitake mushroom extract containing beta-glucan (approximately 20% by weight), 1 to 100 mg
[0086] Formulation C An orally administrable composition comprising: Broccoli Seed Extract Broccoli sprout extract Maitake mushroom extract Ascorbic acid Hydroxypropyl methylcellulose Microcrystalline cellulose cornstarch Ethyl cellulose Croscarmellose sodium Sodium starch glycolate Crospovidone silicon dioxide Sodium Alginate Medium-chain triglycerides Maltodextrin oleic acid Magnesium stearate stearic acid [Example]
[0087] A hydrophobic interaction chromatography (HILIC) method was developed, including the following conditions: Column: Waters BEH Amide, 1.7 μm particle size; 2.1 mm x 100 mm Mobile phase: 20% 10 mM ammonium acetate, pH 5.0; 80% acetonitrile; Separation mode: Isocratic Column temperature: 70℃ Flow rate: 0.7ml / min The above conditions allow for the isolation of five typical cruciferous glucosinolates, including the sulforaphane precursor, glucoraphanin. [Example]
[0088] Glucoraphanin consumption as a function of ascorbic acid concentration Approximately 250 mg of broccoli seed extract containing approximately 12% glucoraphanin by weight was subjected to hydrolysis with a fixed concentration of broccoli sprout-derived myrosinase in the presence of variable concentrations of ascorbic acid ranging from 0 to 600 μmol / L. The reaction mixture was temperature-controlled at 38°C, and aliquots were removed every 15 minutes for 60 minutes, and the glucoraphanin concentration was determined by chromatography. The rate of glucoraphanin consumption was interpreted as its rate of conversion to sulforaphane. Graphical representation of the reduction in glucoraphanin content as a function of increasing ascorbic acid concentration resulted in a series of linear plots, with the slope of the linear regression line reflecting the rate of glucoraphanin consumption in μmol / min. It is clear that in the presence of ascorbic acid at a concentration of 600 μmol / L, the reaction rate increased 13-fold compared to that proceeding in the absence of the modulating effect of ascorbic acid.

[0091] To further elucidate the role of ascorbic acid in regulating myrosinase activity, a two-part experiment was conducted. All solutions were prepared in 20 mM Tris-buffered saline at pH 7.5, previously identified as optimal for myrosinase activity; each sample tube contained an accurately weighed 100 mg of freeze-dried broccoli powder as the source of myrosinase. The experiment was carried out at 38°C for 2 hours, with sample aliquots withdrawn at 30-minute intervals and assessed for both glucoraphanin and sulforaphane content by HPLC. A strongly acidic "stop" solution was utilized to immediately inhibit further myrosinase activity in the withdrawn aliquots. Control samples contained no ascorbic acid, and enzymatic conversion proceeded without cofactor assistance.
[0092] Part 1. Increasing amounts of broccoli seed extract (approximately 12% glucoraphanin by weight) ranging from 250 mg to 500 mg were added in the presence of a fixed concentration of ascorbic acid (1 mmol / liter).
[0093] Part 2. Keeping the amount of broccoli seed extract fixed at 250 mg, the concentration of ascorbic acid was varied from 0.4 mmol / liter to 3.8 mmol / liter.
[0094] The following table shows glucoraphanin and sulforaphane expressed in μmoles. It is clear that the conversion of glucoraphanin to sulforaphane was complete within the first 30 minutes in most reaction mixtures. However, careful examination of the enzymatic conversion occurring in control samples without the stimulating effect of ascorbic acid indicates equimolar conversion of glucoraphanin to sulforaphane; i.e., the amount of glucoraphanin consumed results in an equal amount of sulforaphane produced.
[0095] [Table 2]
[0096] In part 2 of the experiment, the modulatory effect of increasing concentrations of ascorbic acid on myrosinase activity was evaluated. An initial, apparently linear increase in the myrosinase-promoted conversion of glucoraphanin to sulforaphane was observed up to an ascorbic acid concentration of approximately 2 mmol / L, followed by a significant leveling off thereafter.
[0097] Finally, examination of sulforaphane yield after 30 minutes in Part 1 of the experiment indicates that a fixed amount of myrosinase contained in 100 mg of freeze-dried broccoli sprout powder in the presence of 1 mmol / L ascorbic acid can produce at least 200 μmol of sulforaphane in a predictable, linear fashion. Figures 1, 2, 3, and 4 show the results of this study. [Example]
[0098] Conversion of glucoraphanin to sulforaphane in the presence of simulated intestinal fluid.
[0099] Simulated intestinal fluid (SIF) powder (a commercially available concentrate that closely approximates human intestinal contents in terms of composition, pH, and ionic strength) was used. Experiments were performed using a USP dissolution apparatus 2 (paddle type), in which 500 ml of simulated intestinal fluid was dispensed into six dissolution vessels along with 150 mg of freeze-dried broccoli sprout powder as a source of myrosinase. Ascorbic acid concentrations varied from 0.25 to 1.00 mmol / L in vessels 1–4; vessel 5 contained 1 mmol / L ascorbic acid plus 3.125 g of pancreatin (8x USP); vessel 6 contained 1 mmol / L ascorbic acid plus 3.125 g of pancreatin (8x USP) and double the amount of freeze-dried broccoli sprout powder (300 mg). After the vessels were brought to 38°C, 250 mg of glucoraphanin-rich (12% by weight) broccoli seed extract was added to each, and the resulting suspensions were stirred at 75 RPM for 2 hours. Aliquots were removed every 15 minutes and assayed for sulforaphane. Figure 4 shows a direct correlation between the high yield of sulforaphane and the high concentration of ascorbic acid, particularly in the first stage of the experiment. [Example]
[0100] The following study was conducted to examine the effects of a combination of sulforaphane and a 20% β-glucan-containing Maitake mushroom extract on the gene expression of Nad(P)H:quinone oxidoreductase 1 (NQO-1). NQO-1 encodes a protein that can metabolize estrogen quinones and prevent them from forming DNA adducts that cause mutations and ultimately carcinogenesis. Increased NQO-1 expression is beneficial for breast, colon, liver, lung, skin, and prostate health.
[0101] In this study, the macrophage cell line RAW264.7 was treated for 24 hours with DMSO (vehicle control), sulforaphane (SFN), Maitake mushroom extract (Grafica edodes) with approximately 20% β-glucan content, or a combination of sulforaphane and Maitake mushroom extract. Specifically, cells were treated with one of the following: (i) DMSO (vehicle control), (ii) 0.5 μM SFN, (iii) 250 μg / ml Maitake mushroom, (iv) 500 μg / ml Maitake mushroom, (v) 750 μg / ml Maitake mushroom, (vi) 0.5 μM SFN and 250 μg / ml Maitake mushroom, (vii) 0.5 μM SFN and 500 μg / ml Maitake mushroom, and (viii) 0.5 μM SFN and 750 μg / ml Maitake mushroom. Gene expression of NQO-1 was analyzed by quantitative RT-PCR. The results, presented in Figure 5, show that:
[0102] [Table 3]
[0103] The results show that the combination of sulforaphane and Maitake mushroom extract had a synergistic effect compared to each component alone. This effect was found to be more than simply additive. [Example]
[0104] The following study was conducted to investigate the effect of a combination of sulforaphane and a shiitake mushroom extract containing 40% alpha-glucan on the gene expression of Nad(P)H:quinonequinone oxidoreductase 1 (NQO-1).
[0105] In this study, the macrophage cell line RAW264.7 was treated for 24 hours with DMSO (vehicle control), sulforaphane (SFN), a shiitake mushroom extract (L. edodes) with at least 20% α-glucan content, or a combination of sulforaphane and L. edodes mushroom extract. Specifically, cells were treated with one of the following: (i) DMSO (vehicle control), (ii) 0.5 μM SFN, (iii) 100 μg / ml shiitake, (iv) 250 μg / ml shiitake, (v) 500 μg / ml shiitake, (vi) 0.5 μM SFN and 100 μg / ml shiitake, (vii) 0.5 μM SFN and 250 μg / ml shiitake, and (viii) 0.5 μM SFN and 500 μg / ml shiitake. Gene expression of NQO-1 gene expression was analyzed by quantitative RT-PCR. The results, presented in Figure 6, show the following:
[0106] [Table 4]
[0107] The results demonstrate that the combination of sulforaphane and shiitake mushroom extract had a synergistic effect compared to each component alone. This effect was found to be more than merely additive. [Example]
