The field of the invention is compositions and methods for nutritional supplements, especially as it relates polyphenols and polyphenol mixtures commonly associated with a diet rich in fruits and vegetables and their use in conditions, disorders, and diseases associated with various enzymes inhibited by such polyphenol mixtures.
The background description includes information that may be useful in understanding the present disclosure. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art.
All publications and patent applications herein are incorporated by reference to the same extent as if each individual publication or patent application were specifically and individually indicated to be incorporated by reference. Where a definition or use of a term in an incorporated reference is inconsistent or contrary to the definition of that term provided herein, the definition of that term provided herein applies and the definition of that term in the reference does not apply.
There is a considerable variety of vitamins and other isolated nutritional compounds, and alleged benefits of such compounds include, among numerous other effects, immune support, anti-inflammatory effects, anti-ageing effects, cardiac support, and digestive support. Unfortunately, there is only a rather small body of evidence that substantiates some aspects of these alleged benefits when these vitamins and other isolated nutritional compounds are ingested. Similarly, where the nutritional supplement is an extract or powdered form of a plant part, various benefits are advertised, but actual benefits are often poorly or even not at all proven. Moreover, isolated nutritional compounds as well as individual plant extracts and concentrates are generally not reflective of a healthy diet.
Notably, there are certain geographic and ethnographic diet types that are associated with overall health, longevity, and/or physical resilience, and such beneficial effects are indeed well documented and substantiated. For example, the Mediterranean diet is typically associated with lower cardiovascular risk factors (see e.g., Nutrients 2018, 10, 379; doi:10.3390/nu10030379), lower inflammatory and metabolic biomarkers, a reduction in risk of Alzheimer's disease (see e.g., J Alzheimers Dis. 2010 ; 22(2): 483-492.), and with a reduction in certain inflammatory markers (see e.g., Nutrients 2018, 10, 62; doi:10.3390/nu10010062). One common ingredient class found in such diets are polyphenols, and various studies have been published regarding specific benefits of individual dietary polyphenols (see e.g., Inhibitory Properties of Phenolic Compounds Against Enzymes Linked with Human Diseases: URL: dx.doi.org/10.5772/66844), and selected colored polyphenols (see e.g., Annu. Rev. Food Sci. Technol. 2020. 11:10.1-10.38). However, due to the complexity and large number of chemically distinct polyphenols, many studies only focus on single polyphenols and particular biochemical effects of such compounds or provide general epidemiological information without more detailed molecular characterization of the diets.
In an effort to supplement a diet with multiple polyphenols, various supplements are known. For example, Vital Reds (by Gundry MD) provides a commercially available concentrated polyphenol powder blend from a number of red colored plant materials to increase energy and improve digestion. Such blend advantageously includes a variety of chemically distinct polyphenols. However, the selection of plant materials used as a source of polyphenols is not reflective of common dietary intake. Similarly, Oxxynea by Fytexia, a commercially available mixture of grape, olive, pomegranate, green tea, grapefruit, bilberry, and orange extracts is offered as an antioxidant formulation to protect cells from oxidative stress (see e.g., Oxxynea by Fytexia). While beneficial to reduce oxidative stress, the source ingredients for such antioxidant formulation are once more not reflective of a common dietary intake. Surprisingly, despite the numerous beneficial components found in various dietary supplements, there is no supplement that is expected to provide the various benefits of a Mediterranean diet, and particularly the benefits of colored polyphenolic components in Mediterranean diet.
Thus, even though various nutritional supplements are known in the art, all or almost all of them suffer from various disadvantages. Consequently, there is a need to provide improved compositions and methods for nutritional supplements, and especially beneficial/synergistic combinations of polyphenols known to be associated with healthy diets such as the Mediterranean diet.
The inventor has now discovered various compositions and methods for specific combinations of polyphenols and/or polyphenol-rich materials (e.g., extracts and powders) commonly found in food items of the Mediterranean diet that exhibited, when combined, numerous benefits associated with the benefits of the Mediterranean diet. Indeed, the compositions and methods disclosed herein had substantial, and in some cases significant synergistic effect on a variety of molecular biomarkers associated with the benefits of the Mediterranean diet such as markers for ageing, senescence, inflammation, immune function, NAD/energy metabolism, and the gut microbiome.
In one aspect of the inventive subject matter, the inventor contemplates a nutritional composition that comprises a nutritionally acceptable carrier in combination with a plurality of chemically distinct polyphenols from plant materials having a red color, a green color, an orange-yellow color, and a purple-blue color. Preferably, the chemically distinct polyphenols from the plant materials are present as a synergistic combination with respect to inhibition of at least one biochemical marker selected from the group consisting of BACE1, CD38, CD73, CDK5, JAK1, JAK2, and JAK3.
For example, in some embodiments the red colored plant materials comprise at least one (or two, or three, or all of) of an apple extract, a pomegranate extract, a tomato powder, and a beet root powder, wherein the green colored plant materials comprise at least one (or two, or three, or all of) of an olive extract, a rosemary extract, a green coffee bean extract, and a kale powder, wherein the orange-yellow colored plant materials comprise at least one (or two, or three, or all of) of an onion extract, a ginger extract, a grapefruit extract, and a carrot powder, and wherein the purple-blue colored plant materials comprise at least one (or two, or three, or all of) of a grape extract, a blueberry extract, a currant powder, and an elderberry powder.
In further aspect of the inventive subject matter, the chemically distinct polyphenols further inhibit at least one additional biochemical marker selected from the group consisting of ARG-1, ARG-2, SIRT-1, CD39, IDO1, IDO2, NAMPT, PCSK9, CD47, and Cathepsin S. Moreover, contemplated compositions may further inhibit Keap/Nrf2 binding and/or ACE2/Spike binding.
Most typically, but not necessarily, the composition is formulated in single dosage units for oral administration (e.g., each containing between 50 and 1,000 mg of the composition), which may be formulated as a capsule, a gummy, or a powder. Where desired, the composition may further comprise a vitamin, a dietary trace element or mineral, a nicotinamide riboside, a probiotic, and/or a prebiotic.
Therefore, in another aspect of the inventive subject matter, the inventor contemplates a nutritional composition that includes a nutritionally acceptable carrier in combination with a plurality of chemically distinct polyphenol-containing plant materials having a red color, a green color, an orange-yellow color, and a purple-blue color.

For example, the apple extract, the pomegranate extract, the olive extract, the rosemary extract, the green coffee bean extract, the onion extract, the ginger extract, the grapefruit extract, the grape extract, and the blueberry extract may be ethanol extracts or ethanol/water extracts.
In such compositions the combination of plant materials is a synergistic combination with respect to inhibition of at least one biochemical marker selected from the group consisting of BACE1, CD38, CD73, CDK5, JAK1, JAK2, and JAK3, and especially with respect to inhibition of BACE1, CD38, and CD73. Preferred compositions further inhibit at least one additional biochemical marker selected from the group consisting of ARG-1, ARG-2, SIRT-1, CD39, IDO1, IDO2, NAMPT, PCSK9, CD47, and Cathepsin S, and may also inhibit Keap/Nrf2 binding and/or ACE2/Spike binding.
As before, it is preferred (but not needed) that the composition is formulated in single dosage units for oral administration. Typically, the dosage unit contains between 50 and 1,000 mg of the composition, and is formulated as a capsule, a gummy, or a powder. Where desired, contemplated compositions may further comprise a vitamin, a dietary trace element or mineral, a nicotinamide riboside, a probiotic, and/or a prebiotic.
Among other uses, contemplated compositions will be effective to treat and/or reduce a symptom of inflammatory condition, a cardiovascular condition, a neurological condition, a metabolic condition, and a cancer.

For example, the composition may be administered to thereby provide immune support, metabolic support, support longevity, support central nervous system (CNS) function, reduce an inflammatory response, reduce effects of cardiovascular disease, and reduce the rate of amyloid beta plaque formation.
In further examples of such methods, the composition is orally administered over at least 30 days, typically at a daily dose of between 50 and 1,000 mg. As noted earlier, contemplated compositions may further comprise a step of co-administering a vitamin, a dietary trace element or mineral, a nicotinamide riboside, a probiotic, and/or a prebiotic (which may be performed in the same dosage unit or individually).
In another aspect of the inventive subject matter the inventor also contemplates a method of reducing an NAD+ decrease (e.g., age-related NAD+ decrease) in an individual that includes a step of administering to the individual a synergistic combination of polyphenols from plant materials having a red color, a green color, an orange-yellow color, and a purple-blue color wherein the combination synergistically inhibits CD38. In some embodiments, the polyphenols are provided in from of the plant materials.

In yet another aspect of the inventive subject matter the inventor contemplates a method of supporting cognitive function of an individual that includes a step of administering a synergistic combination of polyphenols from plant materials having a red color, a green color, an orange-yellow color, and a purple-blue color wherein the combination synergistically inhibits BACE1. In some embodiments, the polyphenols are provided in from of the plant materials, and administration increases immune function to thereby support longevity and/or reduces the rate of amyloid beta plaque formation.
Preferably, the red colored plant materials are selected from the group consisting of an apple extract, a pomegranate extract, a tomato powder, and a beet root powder, wherein the green colored plant materials are selected from the group consisting of an olive extract, a rosemary extract, a green coffee bean extract, and a kale powder, wherein the orange-yellow colored plant materials are selected from the group consisting of an onion extract, a ginger extract, a grapefruit extract, and a carrot powder, and wherein the purple-blue colored plant materials are selected from the group consisting of a grape extract, a blueberry extract, a currant powder, and an elderberry powder.
In still another aspect of the inventive subject matter the inventor contemplates a method of supporting central nervous system (CNS) function in an individual that includes a step of administering a synergistic combination of polyphenols from plant materials having a red color, a green color, an orange-yellow color, and a purple-blue color wherein the combination synergistically inhibits CDK5. In some embodiments, the polyphenols are provided in from of the plant materials, and administration reduces age-related cognitive decline.
Preferably, the red colored plant materials are selected from the group consisting of an apple extract, a pomegranate extract, a tomato powder, and a beet root powder, wherein the green colored plant materials are selected from the group consisting of an olive extract, a rosemary extract, a green coffee bean extract, and a kale powder, wherein the orange-yellow colored plant materials are selected from the group consisting of an onion extract, a ginger extract, a grapefruit extract, and a carrot powder, and wherein the purple-blue colored plant materials are selected from the group consisting of a grape extract, a blueberry extract, a currant powder, and an elderberry powder.
In a further aspect of the inventive subject matter the inventor contemplates a method of supporting immune function in an individual that includes a step of administering a synergistic combination of polyphenols from plant materials having a red color, a green color, an orange-yellow color, and a purple-blue color wherein the combination synergistically inhibits at least one of JAK1, JAK2, and JAK3. In some embodiments, the polyphenols are provided in from of the plant materials, and administration reduces a symptom of rheumatoid arthritis, psoriasis, or inflammatory bowel disease.
Preferably, the red colored plant materials are selected from the group consisting of an apple extract, a pomegranate extract, a tomato powder, and a beet root powder, wherein the green colored plant materials are selected from the group consisting of an olive extract, a rosemary extract, a green coffee bean extract, and a kale powder, wherein the orange-yellow colored plant materials are selected from the group consisting of an onion extract, a ginger extract, a grapefruit extract, and a carrot powder, and wherein the purple-blue colored plant materials are selected from the group consisting of a grape extract, a blueberry extract, a currant powder, and an elderberry powder.
Additionally, the inventor also contemplates a method of inhibiting at least one of BACE1, CD38, CD73, CDK5, JAK1, JAK2, and JAK3 that includes a step of contacting at least one of the BACE1, the CD38, the CD73, the CDK5, the JAK1, the JAK2, and the JAK3 with a plurality of chemically distinct polyphenols from plant materials having a red color, a green color, an orange-yellow color, and a purple-blue color, wherein the chemically distinct polyphenols from the plant materials are a synergistic combination with respect to inhibition of at least one biochemical marker selected from the group consisting of the BACE1, the CD38, the CD73, the CDK5, the JAK1, the JAK2, and the JAK3. In some embodiments, the polyphenols are provided in from of the plant materials.
For example, the red colored plant materials are selected from the group consisting of an apple extract, a pomegranate extract, a tomato powder, and a beet root powder, wherein the green colored plant materials are selected from the group consisting of an olive extract, a rosemary extract, a green coffee bean extract, and a kale powder, wherein the orange-yellow colored plant materials are selected from the group consisting of an onion extract, a ginger extract, a grapefruit extract, and a carrot powder, and wherein the purple-blue colored plant materials are selected from the group consisting of a grape extract, a blueberry extract, a currant powder, and an elderberry powder.
Advantageously, the step of contacting is performed in vivo (e.g., oral administration to a mammal), and administration of the plurality of chemically distinct polyphenols provides immune support, metabolic support, support longevity, supports central nervous system (CNS) function, reduces an inflammatory response, reduces effects of cardiovascular disease, and/or reduces the rate of amyloid beta plaque formation.
Viewed from a different perspective, the inventor also contemplates a method of treating a condition that is associated with activity of at least one of BACE1, CD38, CD73, CDK5, JAK1, JAK2, JAK3, ARG-1, ARG-2, SIRT-1, CD39, IDO1, IDO2, NAMPT, PCSK9, CD47, and Cathepsin S in a mammal. Such method will typically include a step of administering to the mammal a plurality of chemically distinct polyphenols in an amount effective to inhibit at least one of the BACE1, the CD38, the CD73, the CDK5, the JAK1, the JAK2, the JAK3, the ARG-1, the ARG-2, the SIRT-1, the CD39, the IDO1, the IDO2, the NAMPT, the PCSK9, the CD47, and the Cathepsin S. In preferred embodiments, the chemically distinct polyphenols synergistically inhibit BACE1, CD38, CD73, CDK5, JAK1, JAK2, and/or JAK3.
For example, the condition may be an inflammatory condition, a cardiovascular condition, a neurological condition, a metabolic condition, and/or a cancer. Where desired, the plurality of chemically distinct polyphenols are from plant materials having a red color, a green color, an orange-yellow color, and a purple-blue color. For example, the red colored plant materials are selected from the group consisting of an apple extract, a pomegranate extract, a tomato powder, and a beet root powder, wherein the green colored plant materials are selected from the group consisting of an olive extract, a rosemary extract, a green coffee bean extract, and a kale powder, wherein the orange-yellow colored plant materials are selected from the group consisting of an onion extract, a ginger extract, a grapefruit extract, and a carrot powder, and wherein the purple-blue colored plant materials are selected from the group consisting of a grape extract, a blueberry extract, a currant powder, and an elderberry powder. It should also be appreciated that the polyphenols may be provided in from of the plant materials.
Moreover, it is contemplated that the plurality of chemically distinct polyphenols may be orally administered to the mammal, typically at a daily dosage of between 50 and 1,000 mg. Where desired, such methods may further comprise a step of co-administering to the mammal a vitamin, a dietary trace element or mineral, a nicotinamide riboside, a probiotic, and/or a prebiotic.
In still further contemplated embodiments, the chemically distinct polyphenols are administered in an amount effective to inhibit at least three (or at least five or at least ten or all) of the BACE1, the CD38, the CD73, the CDK5, the JAK1, the JAK2, the JAK3, the ARG-1, the ARG-2, the SIRT-1, the CD39, the IDO1, the IDO2, the NAMPT, the PCSK9, the CD47, and the Cathepsin S.
Therefore, and viewed from a different perspective, the inventor also contemplates the use of a plurality of chemically distinct polyphenols to support healthy ageing. Moreover, it is contemplated that the plurality of chemically distinct polyphenols in such use further inhibit SIRT-1, IDO1, IDO2, NAMPT, PCSK9, CD47, Keap/Nrf2 binding, and/or ACE2/Spike binding, and/or that the chemically distinct polyphenols synergistically inhibit the BACE1, the CD38, the CD73, the CDK5, the JAK1, the JAK2, and/or the JAK3.
As before, it is preferred that the red colored plant materials are selected from the group consisting of an apple extract, a pomegranate extract, a tomato powder, and a beet root powder, wherein the green colored plant materials are selected from the group consisting of an olive extract, a rosemary extract, a green coffee bean extract, and a kale powder, wherein the orange-yellow colored plant materials are selected from the group consisting of an onion extract, a ginger extract, a grapefruit extract, and a carrot powder, and wherein the purple-blue colored plant materials are selected from the group consisting of a grape extract, a blueberry extract, a currant powder, and an elderberry powder.
Various objects, features, aspects and advantages of the inventive subject matter will become more apparent from the following detailed description of preferred embodiments, along with the accompanying drawing figures in which like numerals represent like components.
The inventor has discovered that specific combinations of polyphenol-containing materials (and polyphenols found therein) strongly modulated numerous biomarkers associated with the beneficial effects of the Mediterranean diet. In view of these findings, the inventor therefore contemplates various compositions for nutritional supplements and other nutritional products, compositions, and uses in medicinal food, and even use in medicine.
Most notably, the compositions presented herein had substantial and synergistic effects on a number of biomarkers associated with proper immune and CNS function, effective cellular metabolism, and longevity, and showed further significant effect on additional biomarkers associated with inflammatory responses, adverse effects of cardiovascular disease, and/or amyloid beta plaque formation. For example, the compositions and methods presented herein were demonstrated to have significant and beneficial effects on multiple enzymatic targets that are involved with numerous aspects of health and healthy ageing such as ARG-1, ARG-2, SIRT1, BACE1, Cathepsin S, CDK5, IDO1, IDO2, NAMPT, PCSK9, CD47, CD38, JAK1, JAK2, JAK3, CD39, and CD73, Keap/Nrf2. Viewed from a different perspective, it should be appreciated that the compositions presented herein are useful to beneficially affect multiple pathways associated with health and healthy ageing via inhibition of key signaling components and/or enzymes in these pathways. Remarkably, the observed modulation of these biomarkers using the compositions presented herein paralleled the profile of biomarkers in individuals that adhered to the Mediterranean diet and individuals with significant longevity.
For example, arginase 1 (ARG1) and arginase 2 (ARG2) are key enzymes in the urea cycle, cleaving L-arginine to form urea and L-omithine. The urea cycle provides protection against excess ammonia, while L-ornithine is required for cell proliferation, collagen formation, and other important physiological functions. Notably, increases in arginase activity in mammals have been linked to dysfunction and pathologies of the cardiovascular system, kidney, and central nervous system, and also to dysfunction of the immune system and development of cancer. Two important aspects of the excessive activity of arginase may be involved in diseases. First, overly active arginase can reduce the supply of L-arginine needed for the production of nitric oxide (NO) by NO synthase. Second, excessive quantities of L-ornithine can lead to structural problems in the vasculature, neuronal toxicity, and abnormal growth of tumor cells (see e.g., Physiol Rev 98: 641-665, 2018). Furthermore, studies have demonstrated that increased formation of reactive oxygen species and key inflammatory mediators promote a pathological elevation of arginase activity. As such, inhibition of ARG1 and ARG2 is thought to beneficially counteract the adverse effects of arginase overactivity. As is shown on more detail below, contemplated compositions were effective in inhibiting ARG1 and ARG2 activity even at relatively low concentrations.
In another example, sirtuin1 (SIRT1) is a nuclear enzyme that deacetylates transcription factors that contribute to cellular regulation, and particularly to reaction to stressors. For example, SIRT1 deacetylates members of the PGC1-alpha/ERR-alpha complex, which are critical metabolic regulatory transcription factors, and deacetylates/deactivates the p53 protein, which is a key factor in many neoplastic diseases. SIRT1 was also demonstrated to play a role in activating T helper 17 cells, which contribute to autoimmune disease. As is shown in more detail below, contemplated compositions were effective in mildly inhibiting SIRT1 activity at relatively moderate concentrations.
In yet another example, beta-secretase 1 (BACE1) has been shown to be essential for the generation of β-amyloid in Alzheimer's disease and has also been reported to be associated with cognitive decline and decline in central nervous system (CNS) function (see e.g., Molecules. 2017 Oct. 13;22(10):1723). Indeed, β-amyloid accumulation is a hallmark of ageing, and as such inhibitory compounds are thought to beneficially decelerate or even stop β-amyloid accumulation and as such preserve or maintain cognitive abilities and CNS function. As is described in more detail below, contemplated compositions have shown remarkable, strong, and even synergistic effect with regard to BACE 1 inhibition.
In yet another example, higher levels of Cathepsin S have been reported to be associated with higher risk of mortality and were in some studies also associated with higher risk of cardiovascular mortality (e.g., JAMA, Sep. 14, 2011—Vol 306, No. 10 1113). Other experimental studies have suggested that cathepsin S activity is involved in the development of cardiovascular disease via promotion of atherosclerotic plaques and destabilization of advanced plaques. Moreover, cathepsin S activity was also implicated in the development of cancer via stimulation of cancer cell migration and tumor angiogenesis, and higher levels of Cathepsin S activity was reported to be correlated with ageing of the brain. As such, reduced levels of Cathepsin S activity are believed to beneficially counteract these risks. Notably, contemplated compositions have shown remarkable and strong inhibitory effect with regard to BACE 1 inhibition.
Likewise, cyclin-dependent kinase 5 (CDK5) has been found to be essential to proper CNS function and its role in peripheral tissue and disease is growing. For example, acute CDK5 inhibition has a high potential therapeutic value to prevent neuronal injury in the events of stroke or brain injury, or during high-risk surgeries, such as neurovascular or cardiovascular surgeries, or potentially during prolonged, complicated labors. Pharmacological inhibition of CDK5 has been shown to protect neurons under a range of different stressful conditions and ageing (see e.g., Curr Pharm Des. 2016 ; 22(5): 527-534). Once more, contemplated compositions have shown remarkable, strong, and synergistic inhibitory effect with regard to CDK5 inhibition.
In still other example, Janus kinases 1, 2, and 3 (JAK1, JAK2, JAK3) are implicated in the regulation of cell cycle and cancer, presumably via NF-kB activation (see e.g., Cells 2020, 9, 1451). Moreover, small-molecule drugs that inhibit Janus kinases (JAK1-3) were essential signaling mediators downstream of many proinflammatory cytokines and have gained traction as safe and efficacious options for immune-mediated disorders. Not surprisingly, inhibition of JAKs has emerged as leading potential treatment of inflammation-driven pathologies like rheumatoid arthritis, psoriasis, and inflammatory bowel disease, as well as cardiovascular disease. Notably, contemplated compositions have shown remarkable, strong, and synergistic inhibitory effect with regard to JAK1, JAK2, and JAK3 inhibition (especially at high concentrations).
In still further examples, inhibition of indoleamine 2,3-dioxygenase-1 (IDO1) has emerged as a new treatment strategy for immune support, and particularly in the reversion of tumor-mediated immune suppression (see e.g., Cancer Res. 2017 December 15; 77(24): 6795-6811). Similarly, indoleamine 2,3-dioxygenase-2 (IDO2) has been implicated more recently in cancer, inflammation and immune control, and significant resources have been expended to identify IDO2 specific inhibitors. Increases in IDO1 and IDO2 activity have also been observed as a function of ageing (e.g., Immunity & Ageing 2011, 8:9), along with age related increase in inflammation, autoimmune disorders and malignancies. Remarkably, and as is shown in more detail below, contemplated compositions have shown strong inhibitory effect with regard to IDO1 and IDO2 inhibition.
With respect to energy metabolism, NAMPT and CD38 are known to modulate NAD+ in cells and as such are thought to be essential in maintaining and supporting of cellular energy and proper metabolic function. Indeed, overactivity of CD38 has been reported to increase with senescence (see e.g., Biochem Biophys Res Commun. 2019 May 28; 513(2): 486-493), cancer and ageing diseases (e.g., Trends Pharmacol Sci. 2018 April ; 39(4): 424-436), immunomodulation and metabolic diseases (see e.g., FIMMU May 2019, Vol. 10, Article 1187). On that backdrop, inhibition of CD38 is believed to reduce or even prevent diseases associated with CD38 overactivity. On the other hand, nicotinamide phosphoribosyltransferase (NAMPT) mediates the rate-limiting step of the NAD salvage pathway that maintains cellular bioenergetics and provides a necessary substrate for functions essential to cells, and especially rapidly proliferating cancer cells. Once more, contemplated compositions have shown strong and synergistic inhibitory effect with regard to CD38 inhibition, and strong inhibition with respect to NAMPT activity.
Moreover, overactivity of CD39 and CD73 have been reported to contribute to immune suppression, suppression of checkpoint inhibition in tumors, and other aspect of immune regulation (see e.g., FIMMU June 2017, Volume 8, Article 727; Immunol Rev. 2017 March; 276(1): 121-144). In addition, centenarians showed a significantly lower expression of CD39 and CD73 as compared to younger individuals (here: octogenarians), suggesting that the levels of CD39 as well as CD73 mRNA could be a hallmark of successful human ageing. Viewed from a different perspective, aging is associated with a decline in immune function and so contributes to the increased susceptibility to infectious diseases and higher incidence of malignant disease. Therefore, lower levels of CD39 activity are thought to be directly associated with healthy aging and longevity. Remarkably, contemplated compositions had a significant and synergistic effect in the inhibition of CD73 and a profound inhibitory effect on the activity of CD39 as is shown in more detail below. Likewise, CD47 inhibition was shown to lead to stimulation of phagocytosis of cancer cells and CD47 blockade not only enhanced the function of innate immune cells but also linked to adaptive immune responses (see e.g., Cell Reports 31,107494 Apr. 14, 2020). Notably, contemplated compositions had a significant inhibitory effect in the inhibition of CD47 as is shown in further detail below.
In yet other examples, proprotein convertase subtilisin/kexin type 9 (PCSK9) has been reported as a contributor to plasma cholesterol levels, and inhibitors targeting PCSK9 have reduced plasma cholesterol in human. Once more, and as shown in more detail below, contemplated compositions had a significant and synergistic effect in the inhibition of PCSK9.
Additionally, the Keap1-Nrf2 pathway is a major regulator of cytoprotective responses to endogenous and exogenous stresses caused by reactive oxygen species (ROS) and Nrf2 activates expression of a variety of genes encoding stress response proteins. Inhibitors of Keap1-Nrf2 binding are therefore thought to increase expression of stress response related proteins. Remarkably, and as shown in more detail below, contemplated compositions had a significant and effect in the inhibition of Keap1-Nrf2 binding (and as such increase availability of Nrf2).
Finally, the inventor also discovered that contemplated compositions also had inhibitory effect in ACE2-Spike protein binding, which is implicated in viral propagation of corona viruses, and especially Sars-CoV2. As will be readily appreciated, contemplated compositions may therefore provide at least some protective effect against corona viruses, and especially Sars-CoV2.
Based on his extensive research, the inventor has now discovered that specific blends of selected plant materials common in the Mediterranean diet can be prepared that mimic the benefits of the Mediterranean diet as evidenced in the modulation of biomarkers. Preferably, such blends are combinations of colored plant materials that belong to a number (e.g., at least two, at least three, or at least four) of different color groups, and particularly plant materials having a red color, green color, orange/yellow color, and/or purple/blue color. For example, in one embodiment of contemplated compositions, polyphenol-containing products/extracts were obtained from red colored source materials that included an apple extract, a pomegranate extract, tomato powder, and beet root; from green colored source materials that included an olive extract, rosemary extract, green coffee bean extract, and kale; from orange/yellow colored source materials that included an onion extract, a ginger extract, a grapefruit extract, and carrot; and from purple/blue colored source materials that included a grape extract, a blueberry extract, currant, and elderberry, and the particular ingredients and proportions are described in more detail below. Viewed from a different perspective, contemplated compositions will therefore include a large number of polyphenols that below to at least two, or at least three, or at least four different polyphenolic classes, including organic acids, phenolics, flavonols, flavanols, anthocyanins, chlorogenic acids, betacyanins, etc. As will be readily appreciated, the particular choice of a plant material will depend on the desired (polyphenolic) component in the plant material and its effect on a particular biological system and/or signaling pathway.
Of course, it should also be appreciated that the plant materials may be provided in various forms, including whole plant materials or portions thereof (e.g., root, fruit, leaves, etc.) in fresh or dried form, juices or macerates from plant materials or portions thereof in fresh or dried form, and aqueous or aqueous/alcoholic extracts and chromatographic fractions of the aforementioned plant materials. Still further, it should be noted that one or more polyphenols of the plant materials may even be provided as purified (natural isolated or synthetic) chemical entities, typically with a chemical purity of at least 90%, or at least 95%, or at least 98%, or at least 99%. However, it should be recognized that in most embodiments the plant materials will be complex mixtures to provide a combination of desired biological effects on a number of distinct molecular entities (e.g., enzymes, receptors, ion channels) where at least some of the biological effects (e.g., at least one, or at least two, or at least three, etc.) are synergistic. Moreover, it is contemplated that the biological effects on the particular molecular entities will also be complementary in biological function. Therefore, and based on the testing and desired targets as described in more detail below, it should be appreciated that the compositions of the inventive subject matter may be formulated to meet a particular need. However, in especially preferred aspects contemplated compositions will inhibit multiple targets (e.g., at least two, at least three, at least four, etc.) in multiple and distinct (e.g., at least two, at least three, at least four, etc.) signaling pathways.
Consequently, and viewed from a different perspective, it should be appreciated that the mechanism of action of contemplated compositions is not limited to a single specific function (e.g., antioxidant) or limited to a specific chemical category (e.g., vitamins), but in fact complementarily and synergistically provides multiple biological activities across distinct metabolic and signaling pathways. As such, contemplated compositions and methods target a variety of biological systems, including energy metabolism, immune function, neural and CNS function, cardiac function, inflammation, etc. Notably, and as is described in more detail below, the compositions contemplated herein also affected a number of biomarkers associated with longevity (e.g., in blue zone populations such as Mediterranean population, Okinawan population, etc.) In addition, it is contemplated that the plant materials will also provide a variety of micro-nutrients to assist or complement the functions of the polyphenols and other colored pigments present in the compositions.
Consequently, it should be appreciated that the compositions contemplated herein may be advantageously used as a stand-alone product to support various aspects of health and healthy ageing such as support of proper immune function, support to reduce inflammation, support of normal NAD+ levels, support of cardiac health. In this context, it should be noted that the term “support” when used in conjunction with a physiological function or condition is intended to mean prevent decline of one or more components or activities of the component(s) associated with the physiological function or condition, at least partially reverse decline of one or more components or activities of the component(s) associated with the physiological function or condition, maintain normal function of one or more components or activities of the component(s) associated with the physiological function or condition, prevent abnormal overactivity (or over-expression) of one or more components associated with the physiological function or condition, and/or at least partially reverse abnormal overactivity (or over-expression) of one or more components associated with the physiological function or condition. Alternatively, the compositions contemplated herein may also be combined with other nutritional supplements and/or vitamins to provide beneficial effects otherwise not obtainable with such supplements or vitamins. In this context, it should be appreciated that most, if not all of the biomarkers tested herein were not substantially modulated by multivitamin compositions as is shown in more detail below. Thus, it should be recognized that the compositions resented herein present a new and different class of health support with a variety of beneficial effects that reach beyond the benefits of a multivitamin formulation.
In further contemplated aspects of the inventive subject matter it should be appreciated that the compositions presented herein may be formulated in a variety of forms, and particularly preferred formulations include those in combination with a nutritionally or pharmaceutically acceptable carrier, most preferably for oral administration (however, parenteral administration is also expressly contemplated). Therefore, contemplated compositions can be formulated as solid or a liquid product. For example, where contemplated compositions are formulated as a solid product, suitable product forms include single dosage unit formulations such as capsules, tablets, and powders, while other solid formulations include snack bars, gummies, or other edible products onto which the composition is coated (e.g., onto cereal) or into which the composition is mixed or layered (e.g., into chewing gum). In another examples, where contemplated compositions are formulated as a liquid product, suitable product forms include flavored and/or carbonated beverages (e.g., tea, juice), functional beverages (e.g., sports or energy drinks) or infusions, or liquid dairy product (e.g., yoghourt, kefir).
Therefore, contemplated compositions may be provided in bulk, as part of an edible or drinkable product, and/or provided in single dosage units for consumption. Most typically, the daily dosage for contemplated compositions (excluding the carrier) is preferably at least 10 mg, or at least 100 mg, or at least 200 mg, or at least 300 mg, or at least 400 mg, or at least 500 mg, or at least 750 mg, or at least 1,000 mg, or at least 1,500 mg. For example, suitable dosages will be between 10-100 mg, or between 100-200 mg, or between 200-400 mg, or between 300-600 mg, or between 400-800 mg, or between 600-1,000 mg, or between 1,000-2,000 mg.
As will be readily appreciated, contemplated compositions may further be combined with one or more additional ingredients to impart further desirable functionalities, and suitable additional ingredients include vitamins (e.g., single vitamins, or vitamin blends such as multivitamin blends), dietary trace elements or minerals (e.g., individual elements or minerals, or mixtures of multiple elements or minerals in various forms), various specialty compounds and mixtures (e.g., compositions comprising nicotinamide riboside, prebiotics, human milk oligosaccharides), and/or one or more probiotic microorganisms (e.g., Lactobacillus spec., Bifidobacterium spec., Leukonostoc spec., Saccharomyces boulardii, etc.).
Of course, it should be recognized that the compositions according to the inventive subject matter may be administered not only to a human, but also to other non-human mammals, and especially livestock and companion animals (e.g., dogs, cats, horses). Administration will typically be between once daily and three times daily (and in some cases even more) over a period of at least two days, three days, five days, 1 week, 2-4 weeks, 1-3 months, and even longer. Most typically, administration can be performed for a period sufficient to provide at least symptomatic relief of a condition (e.g., pain and swelling associated with inflammation, low energy level, frequent infections, etc.), or prophylactically to avoid or help reduce severity of a health condition.

In the following experiments, the inventor sought to determine whether the representative compositions had an effect on ARG1 and ARG2. Reagents used are shown in the Tables 9-10 below and tested as stated unless indicated otherwise (nor-NOHA is reference compound).
Assay conditions: The assay was performed using human recombinant ARG1 or ARG2 as enzymes and thioarginine as substrate. The UV absorbance at 412 nm was correlated with the amount of reaction product of ARG1/ARG2. The test sample (HP Color Blend) was dissolved to 1% (w/v) with 70% (w/v) EtOH and filtered through 0.22 μm; nor-NOHA was dissolved in 100% (w/v) DMSO to 10 mM. 5 μl of 20× sample solutions were added to 90 μl of substrate, and reactions were started by the addition of 5 μl of 20× ARG1/ARG2 solutions. For the negative control (Blank), 5 μl of the assay buffer was added instead of the ARG1/ARG2. The resulting 100 μl reaction mixture contained the indicated amount of the samples, 225 μM thioarginine, the detection reagent, and 30 nM ARG1 or 5 nM ARG2 in 1× ARG Assay Buffer. All reactions were conducted at room temperature and incubated for 30 minutes, ensuring that all wells, containing either samples or controls, contained 0.7% (v/v) EtOH final concentration to discard any solvent effect. UV absorbance readings were done at times 0 and 30 minutes to get net values. Absorbance was measured using a Tecan Infinite M1000 microplate reader.
Data Analysis: Experiment was performed in duplicate at each concentration. The data were analyzed using the software GraphPad Prism. In the absence of the compound, the net absorbance (At) in each data set was defined as 100% activity. In the absence of ARG1/ARG2, the net absorbance (Ab) in each data set was defined as 0% activity. The percent activity in the presence of each compound was calculated according to the following equation: % activity=[(A−Ab)/(At−Ab)]×100, where A=the absorbance in the presence of the compound. The percent inhibition was calculated according to the following equation: % inhibition=100−% activity.
Results: Notably, significant inhibitory activity was found for both ARG-1 and ARG-2 across all tested concentrations as is shown in Tables 11-12 below. As can be readily seen from the results, inhibition relative to the reference inhibitor was significant and not specific towards one or the other of ARG-1 and ARG-2 as is also seen from Table 13. Results are also depicted in

After enzymatic reactions, 50 μl of 2× SIRT Developer was added to each well for the SIRT enzymes and the plate was incubated at room temperature for an additional 15 minutes. Fluorescence intensity was measured at an excitation of 360 nm and an emission of 460 nm using a Tecan Infinite M1000 microplate reader.
Data Analysis: SIRT activity assays were performed in duplicates at each concentration. The fluorescent intensity data were analyzed using the computer software, Graphpad Prism. In the absence of the compound, the fluorescent intensity (Ft) in each data set was defined as 100% activity. In the absence of SIRT, the fluorescent intensity (Fb) in each data set was defined as 0% activity. The percent activity in the presence of each compound was calculated according to the following equation: % activity=(F−Fb)/(Ft−Fb), where F=the fluorescent intensity in the presence of the compound.

The reference compound is diluted in 10% DMSO, and 5 μl of the dilution was added to a 50 μl reaction so that the final concentration of DMSO is 1%. The binding reactions were conducted at room temperature for 30 minutes in a 50 μl mixture containing 10mM HEPES, pH7.4, 50 mM EDTA, 150 mM NaCl, 0.05% Tween20, 0.01% BSA, 100 nM Keap1, 5 nM fluorescence probe and the test compound. Fluorescence intensity was measured at an excitation of 475 nm and an emission of 520 nm using a Tecan Infinite M1000 microplate reader.
Data Analysis: All of binding assays were performed in 96-well plates in duplicate. Fluorescence intensity is converted to fluorescence anisotropy using the Tecan Magellan6 software. The fluorescence anisotropy data were analyzed using the computer software, Graphpad Prism. The fluorescence anisotropy (FAt) in the sample with KeapI and the probe in each data set was defined as 100% activity. The fluorescence anisotropy (FAb) in the sample with a compound but without KeapI in each data set was defined as 0% activity. The percent binding efficacy in the presence of the competitor compound was calculated according to the following equation

Reagents used are shown in Tables 64-66 below and tested as stated unless indicated otherwise (*Apigenin was used as reference compound). Table 64 shows the representative composition, while Table 65 shows the colored fractions. Here, DC-5=Yellow Blend, DC-9=Purple Blend, DC-21-Green Blend, DC-13=Red Blend. The red blend included Apple Extract, Pomegranate Extract, Tomato Powder, Beet; the green blend included Olive Extract, Rosemary Extract, Green Coffee Bean Extract, Kale; the orange/yellow blend included Onion Extract, Ginger Extract, Grapefruit Extract, Carrot; and the purple/blue blend included Grape, Blueberry Extract, Currant, and Elderberry as listed above. Staurosporine was used as a reference compound. Table 66 lists the enzymes and substrates used in the assays.
Assay Conditions: The assay was performed using Kinase-Glo Plus luminescence kinase assay kit (Promega). It measures kinase activity by quantitating the amount of ATP remaining in solution following a kinase reaction. The luminescent signal from the assay is correlated with the amount of ATP present and is inversely correlated with the amount of kinase activity. The reference compound was diluted as noted. The compound was diluted in water and 5 μl of the dilution was added to a 50 μl reaction. All of the enzymatic reactions were conducted at 30° C. for 45 minutes. The 50 μl reaction mixture contains 40 mM Tris, pH 7.4, 10 mM MgCl2, 0.1 mg/ml BSA, 1 mM DTT, 10 μM ATP, Kinase substrate and the respective enzyme. After the enzymatic reaction, 50 μl of Kinase-Glo Plus Luminescence kinase assay solution (Promega) was added to each reaction and incubate the plate for 15 minutes at room temperature. Luminescence signal was measured using a BioTek Synergy 2 microplate reader.
Data Analysis: Kinase activity assays were performed in duplicate at each concentration. The luminescence data were analyzed using the computer software, GraphPad Prism. The difference between luminescence intensities in the absence of Kinase (Lut) and in the presence of Kinase (Luc) was defined as 100% activity (Lut−Luc). Using luminescence signal (Lu) in the presence of the compound, % activity was calculated as: % activity={(Lut−Lu)/(Lut−Luc)}×100%, where Lu=the luminescence intensity in the presence of the compound (all percent activities below zero were shown zero in the table).
The results for inhibition using the representative composition are shown in Tables 67-69 and
Tables 70-72 and
CD39:
In further experiments, the inventor sought to determine whether the representative compositions had an effect on the enzymatic activity of recombinant human CD39 using an in vitro enzymatic assay.
Reagents used are shown in Tables 74-77 below and tested as stated unless indicated otherwise (*POM-1 was used as reference compound). Table 74 shows the representative composition at standard concentrations, and Table 75 shows the representative composition at low concentrations. Table 76 shows colored fractions of the representative composition at standard concentrations. Here, D5 is the Yellow Blend, D9 is the Purple Blend, D21 is the Green Blend, D13 is the Red Blend, and D31 is CBD. As before, the red blend included Apple Extract, Pomegranate Extract, Tomato Powder, Beet; the green blend included Olive Extract, Rosemary Extract, Green Coffee Bean Extract, Kale; the orange/yellow blend included Onion Extract, Ginger Extract, Grapefruit Extract, Carrot; and the purple/blue blend included Grape, Blueberry Extract, Currant, Elderberry. Table 77 lists CD39.
Assay Conditions: In general, all assays points were done by following the CD39 and CD73 Inhibitor Screening Assay Kit protocol (BPS Bioscience, #79278 and 72055, respectively). The CD39 enzymatic reactions were conducted in duplicate at room temperature for 30 minutes in a 50 μl mixture containing assay buffer, ATP, CD39 enzymes, and the test compound. Test compounds were preincubated with the enzyme for 30 minutes. Reactions were started by addition of the substrate. The 50 μl reactions were carried out in a 96-well transparent plate. After enzymatic reactions, 100 μl of Colorimetric Detection Reagent was added to the reaction mix. After a 15 minutes incubation, absorbance was measured using a Tecan plate reader at 630 nm.
Data Analysis: Enzyme activity assays were performed in duplicates at each concentration. The Absorbance intensity data were analyzed and compared. In the absence of the compound, the intensity in each data set was defined as 100% (Ce) activity. In the absence of enzyme, the intensity in each data set was defined as 0% (C0) activity. The percent activity in the presence of each compound was calculated according to the following equation: % activity=(C−C0)/(Ce−C0), where C=the intensity in the presence of the compound (all percent activities below zero were shown zero in the table).
Remarkably high and significant inhibitory activity was found for CD39 across all tested concentrations as is shown in Tables 77-78 below, with Table 78 and
The inventor then further investigated whether one or more specific plant materials and their polyphenols were associated with the inhibitory activity against CD39. To that end, the inventor tested two components of the red colored blend: Apple Extract (DCH-IC50X) and Pomegranate extract (DCH-IC50Y) at the low concentration ranges as shown in Table 81 with otherwise identical assay conditions. Results are shown in Table 82 and
In still further experiments, the inventor also investigated whether CD39 could also be inhibited by a multivitamin mix. To that end, a comparative experiment was conducted between a multivitamin mix (denoted as DCH-TIV-1.0 (Adult Centrum Multivitamin)) and the representative composition (denoted as DCH-TIC-0.5) using the same experimental procedure for CD39 as described above. The compositions are shown in Table 83.
The results for this comparison are shown in Table 84 and
CD73:
In still further experiments, the inventor further sought to determine whether the representative compositions had an effect on the enzymatic activity of recombinant human CD73 using an in vitro enzymatic assay.
Reagents used are shown in Tables 85-89 below and tested as stated unless indicated otherwise (*AMPCP or Quercetin were used as reference compound). Table 85 shows the representative composition at standard concentrations, and Table 86 shows colored fractions of the representative composition at standard concentrations. Here, D5 is the Yellow Blend, D9 is the Purple Blend, D21 is the Green Blend, D13 is the Red Blend, and D31 is CBD. As before, the red blend included Apple Extract, Pomegranate Extract, Tomato Powder, Beet; the green blend included Olive Extract, Rosemary Extract, Green Coffee Bean Extract, Kale; the orange/yellow blend included Onion Extract, Ginger Extract, Grapefruit Extract, Carrot; and the purple/blue blend included Grape, Blueberry Extract, Currant, Elderberry. Table 87 lists CD73.
Assay Conditions: In general, all assays points were done by following the CD39 and CD73 Inhibitor Screening Assay Kit protocol (BPS Bioscience, #79278 and 72055, respectively). The CD73 enzymatic reactions were conducted in duplicate at room temperature for 30 minutes in a 50 μl mixture containing assay buffer, ADP, CD73 enzymes, and the test compound. Test compounds were preincubated with the enzyme for 30 minutes. Reactions were started by addition of the substrate. The 50 μl reactions were carried out in a 96-well transparent plate. After enzymatic reactions, 100 μl of Colorimetric Detection Reagent was added to the reaction mix. After a 15 minutes incubation, absorbance was measured using a Tecan plate reader at 630 nm.
Data Analysis: Enzyme activity assays were performed in duplicates at each concentration. The Absorbance intensity data were analyzed and compared. In the absence of the compound, the intensity in each data set was defined as 100% (Ce) activity. In the absence of enzyme, the intensity in each data set was defined as 0% (C0) activity. The percent activity in the presence of each compound was calculated according to the following equation: % activity=(C−C0)/(Ce−C0), where C=the intensity in the presence of the compound (all percent activities below zero were shown zero in the table).
As can be see form the results in Tables 88-90, the inhibition of CD73 by the representative composition and its fractions was remarkably high, especially in comparison to the current reference standard. Table 88 and
To further investigate whether CD73 could also be inhibited by a multivitamin formulation, the inventor performed comparative experiments between the representative composition and a multivitamin composition using the same test procedure as outlined above. Table 91 lists the reagents used in this experiment (DCH-TIV-0.5 denotes the representative composition, and DCH-TIV-1.0 denotes Adult Centrum Multivitamin).
As can be readily seen form the results in Table 92 and
In some embodiments, the numbers expressing quantities of ingredients, properties such as concentration, reaction conditions, and so forth, used to describe and claim certain embodiments of the invention are to be understood as being modified in some instances by the term “about.” Accordingly, in some embodiments, the numerical parameters set forth in the written description and attached claims are approximations that can vary depending upon the desired properties sought to be obtained by a particular embodiment. The recitation of ranges of values herein is merely intended to serve as a shorthand method of referring individually to each separate value falling within the range. Unless otherwise indicated herein, each individual value is incorporated into the specification as if it were individually recited herein.
As used herein, the term “administering” a pharmaceutical or nutraceutical composition refers to both direct and indirect administration of the pharmaceutical or nutraceutical composition, wherein direct administration of the pharmaceutical or nutraceutical composition is typically performed by a health care professional (e.g., physician, nurse, dietitian, etc.), and wherein indirect administration includes a step of providing or making available the pharmaceutical or nutraceutical composition to the health care professional or individual in need thereof for direct administration (e.g., via injection, infusion, oral delivery, topical delivery, etc.). It should further be noted that the terms “prognosing” or “predicting” a condition, a susceptibility for development of a disease, or a response to an intended treatment is meant to cover the act of predicting or the prediction (but not treatment or diagnosis of) the condition, susceptibility and/or response, including the rate of progression, improvement, and/or duration of the condition in a subject.
All methods described herein can be performed in any suitable order unless otherwise indicated herein or otherwise clearly contradicted by context. The use of any and all examples, or exemplary language (e.g. “such as”) provided with respect to certain embodiments herein is intended merely to better illuminate the invention and does not pose a limitation on the scope of the invention otherwise claimed. No language in the specification should be construed as indicating any non-claimed element essential to the practice of the invention.
As used in the description herein and throughout the claims that follow, the meaning of “a,” “an,” and “the” includes plural reference unless the context clearly dictates otherwise. Also, as used in the description herein, the meaning of “in” includes “in” and “on” unless the context clearly dictates otherwise. As also used herein, and unless the context dictates otherwise, the term “coupled to” is intended to include both direct coupling (in which two elements that are coupled to each other contact each other) and indirect coupling (in which at least one additional element is located between the two elements). Therefore, the terms “coupled to” and “coupled with” are used synonymously.
It should be apparent to those skilled in the art that many more modifications besides those already described are possible without departing from the inventive concepts herein. The inventive subject matter, therefore, is not to be restricted except in the scope of the appended claims. Moreover, in interpreting both the specification and the claims, all terms should be interpreted in the broadest possible manner consistent with the context. In particular, the terms “comprises” and “comprising” should be interpreted as referring to elements, components, or steps in a non-exclusive manner, indicating that the referenced elements, components, or steps may be present, or utilized, or combined with other elements, components, or steps that are not expressly referenced. Where the specification or claims refer to at least one of something selected from the group consisting of A, B, C . . . and N, the text should be interpreted as requiring only one element from the group, not A plus N, or B plus N, etc.
