The present disclosure relates to rice protein hydrolysates for modulating inflammation in an individual. More particularly, the present disclosure relates to nutritional compositions comprising rice protein hydrolysates that in specific embodiments reduce inflammation and thereby prevent and/or treat inflammatory conditions and diseases.
Excessive inflammation is widely understood to be a unifying component in many chronic diseases, including vascular diseases, metabolic syndrome, and neurological diseases. Understanding endogenous control points within the inflammatory response could provide new perspectives on disease pathogenesis and treatment approaches. The acute inflammatory response generally has an initiation (early phase) and resolution (late phase). The production of inflammatory cytokines (i.e., Tumor Necrosis Factor alpha, TNFα) is part of the inflammatory process which is characterized by an initial and then a sustained phase that usually ends after resolution of the inflammatory trigger. Often, a breakdown in the regulation of inflammation occurs at the end of sustained inflammatory responses and prolonged TNFα production is often associated with the pathology of many inflammatory diseases. Many therapeutic pharmaceutical agents block or antagonize the initiation steps of acute inflammation but do not have an effect on the late phase resolving inflammation. Therefore the identification of key regulators of sustained TNFα production would provide opportunities to develop new therapeutic inventions for inflammatory diseases.
Prior research does not provide a way to formulate a nutritional product using hydrolyzed proteins without adversely affecting the organoleptic properties of the product, and in particular, taste. Other problems to the development of such products include precipitation difficulties and bitter, salty, sour, and/or beany flavors.
It would therefore be desirable to provide nutritional compositions with components such as moderately hydrolyzed rice proteins that act on only a portion of the inflammatory response, or more predominantly in one phase of the inflammatory response, while still providing the organoleptic properties that consumers have come to expect (i.e., flavor and texture profiles).
Specific embodiments of the invention are generally directed to a nutritional composition for modulating or reducing inflammation in an individual in need thereof, the nutritional composition comprising a rice protein hydrolysate having a minimum degree of hydrolysis of 15%, wherein at least 30% of the rice protein hydrolysate peptides are less than 1000 Da., and no more than 30% of the rice protein hydrolysate peptides are greater than 3000 Da.
Additional embodiments are directed to a method of modulating inflammation in an individual, the method comprising administering to the individual a nutritional composition comprising a rice protein hydrolysate having a minimum degree of hydrolysis of 15%, wherein at least 30% of the rice protein hydrolysate peptides are less than 1000 Da., and no more than 30% of the rice protein hydrolysate peptides greater than 3000 Da.

Certain exemplary embodiments contemplate compositions comprising at least one moderately hydrolyzed rice protein in combination with at least one of: long chain polyunsaturated fatty acids; polyphenols; curcuminoids; antioxidants, including carotenoids, and/or various other immunomodulatory or anti-inflammatory ingredients for controlling diseases and conditions related to inflammation.
These and other features of the nutritional compositions and methods, as well as some of the many optional variations and additions, are described in detail hereafter.
The terms “fat” and “oil” as used herein, unless otherwise specified, are used interchangeably to refer to lipid materials derived or processed from plants or animals. These terms also include synthetic lipid materials so long as such synthetic materials are suitable for oral administration to humans.
The term “shelf stable” as used herein, unless otherwise specified, refers to a nutritional composition that remains commercially stable after being packaged and then stored at 18-24° C. for at least 3 months, or from about 6 months to about 36 months, or from about 12 months to about 18 months.
The term “nutritional composition” as used herein, unless otherwise specified, refers to synthetic formulas including nutritional liquids, nutritional powders, nutritional solids, nutritional semi-solids, nutritional semi-liquids, nutritional supplements, and any other nutritional food composition as known in the art. The nutritional powders in specific embodiments are reconstituted to form a nutritional liquid, all of which comprise one or more of protein, fat, and carbohydrate and are suitable for oral consumption by a human.
The term “nutritional liquid” as used herein, unless otherwise specified, refers to nutritional compositions in ready-to-drink liquid form, concentrated form, and nutritional liquids made by reconstituting the nutritional powders described herein prior to use. In one example, the liquid is a shake.
The term “nutritional powder” as used herein, unless otherwise specified, refers to nutritional compositions in flowable or scoopable form that in specific embodiments are reconstituted with water or another aqueous liquid prior to consumption and includes both spray dried and drymixed/dryblended powders.
The term “nutritional semi-solid,” as used herein, unless otherwise specified, refers to nutritional compositions that are intermediate in properties, such as rigidity, between solids and liquids. Some semi-solids examples include puddings, gelatins, and doughs.
The term “nutritional semi-liquid,” as used herein, unless otherwise specified, refers to nutritional compositions that are intermediate in properties, such as flow properties, between liquids and solids.

The term “synthetic child formula” as used herein, unless otherwise specified, refers to liquid, semi-liquid, solid, and semi-solid human milk replacements or substitutes that are suitable for consumption by a child up to the age of 12 years.
The terms “inflammatory disease” or “inflammatory condition” as used herein, unless otherwise specified, refer to any disease, disorder, or condition characterized by inflammation. Non-limiting examples include vascular diseases, metabolic syndrome, obesity, and neurological diseases, diabetes, and diseases of the gastrointestinal tract, nerves, lungs, skin, muscles, bones, brain, thyroid, blood, cancer, and certain aspects of aging.
The terms “susceptible” and “at risk” as used herein, unless otherwise specified, mean having resistance to a certain condition or disease that is reduced relative to the population as a whole, including being genetically predisposed, having a family history of, and/or having symptoms of the condition or disease.
The terms “modulating” or “modulation” or “modulate” as used herein, unless otherwise specified, refer to the targeted movement of a selected characteristic.
The terms “hydrolyzed protein” or “protein hydrolysate” as used herein, unless otherwise specified, refer to a source of protein which has been subjected to a specific treatment whose primary purpose is to hydrolyze proteins. In this regard, it is conventional in this industry to refer to a protein source which has been subjected to a treatment whose primary purpose is to hydrolyze unhydrolyzed proteins as a source of hydrolyzed proteins, e.g., “rice protein hydrolysate.” In contrast, when a protein source has not been subjected to such a treatment, it is conventional practice to refer to this composition as a source of intact protein, or, more commonly, to say nothing about the hydrolysis of its protein.
A way of referring to the extent of hydrolysis of a hydrolyzed protein is by noting its Degree of Hydrolysis (DH). A protein with a DH value of, for example, 30 refers to protein in which 30% of the total protein is hydrolyzed (or that 30% of the protein's peptide bonds have been cleaved; e.g., if the intact protein contains 100 peptide bonds, and if 30 of these bonds are cleaved by the hydrolysis process, then the DH of the protein after hydrolysis is 30).
The inflammatory response is generally divided into an early phase and a late phase. The early phase refers to acute inflammation that includes all the events of the acute vascular response that follows within seconds of the tissue injury and last for some minutes, and the acute cellular response that takes place over the next few hours. The hallmark of this phase is the appearance of granulocytes, particularly neutrophils, in the tissues. The late phase refers to chronic inflammation and resolution. Chronic inflammation includes a response occurring a day or days after the injury, and is marked by the appearance of a mononuclear cell infiltrate composed of macrophages and lymphocytes. The macrophages are involved in microbial killing, clearing cellular and tissue debris, and in remodeling the tissue. Resolution refers to tissue returning to normal or developing scarring. Complete resolution of an acute inflammatory response and the return of local tissues to homeostasis is an aim for the process, minimizing inflammation's impact to ongoing health.
Surprisingly, it has been found that a moderately hydrolyzed protein ingredient from rice is capable of modulating the late phase inflammatory response without presenting organoleptic issues that are common to hydrolyzed proteins such as undesirable odor or taste. As used herein, “moderately hydrolyzed” refers to a protein hydrolyzed to a DH of at least 15%.
It is well understood that the TLR4-MYD88-TRIF signaling pathway is responsible for the initiation and early phase expression of genes encoding for specific pro-inflammatory cytokines (e.g., TNFα). Another important protein induced during the early phase of T lymphocyte-mediated (TLR-mediated) cellular activation is 4-1BB ligand (4-1BBL, also referred to as CD137L). 4-IBBL is produced on the cell surface of specific macrophages/T cells and functions to generate a new phase of signaling to mediate sustained TNFα production. 4-1BBL is a type 2 trans membrane protein of the TNFα super family. The interaction between 4-1BBL and its receptors provides a co-stimulatory signal enhancing T lymphocytes proliferation and survival, required for sustained TNFα production in macrophages and is rapidly induced in LPS stimulated macrophages.
While not wishing to be bound by theory, it is contemplated that moderately hydrolyzed rice protein from particular sources in specific embodiments inhibit or reduce expression of 4-1BBL and thereby reduce the duration of TNFα production. Long term elevation of pro-inflammatory cytokines (such as TNFα) is often associated with the pathology of inflammatory diseases. Targeted reductions of the late phase 4-1BBL mediated TLR signaling in specific embodiments provide a strategy for treatment of inflammatory diseases while not suppressing the inflammatory response as a whole. In addition, since the moderately hydrolyzed proteins of the present disclosure do not suppress the activation of NF-κB (an early phase response), in specific embodiments, synergistic anti-inflammatory effects are provided by combining these bioactive moderately hydrolyzed proteins with known early phase NF-κB inhibitors, such as curcumin (for example, C3C curcumin), green tea extract, and others.
The present disclosure is directed to nutritional compositions in the form of nutritional liquids, powders, bars, and other food products comprising rice protein hydrolysates as a primary or sole source of protein. The rice protein hydrolysate has a degree of hydrolysis such that the resulting nutritional compositions are physically stable over shelf life and provide favorable organoleptic properties, while providing surprising anti-inflammatory properties.
The nutritional compositions of the present disclosure include one or more rice protein hydrolysates as described herein. The compositions in specific embodiments include one or more rice protein hydrolysates alone or in combination with other immune-modulating or anti-inflammatory ingredients including, but not limited, to long chain polyunsaturated fatty acids (LCPUFAs), polyphenols, anthocyanidins, curcuminoids, isoflavones, and antioxidants, such as carotenoids and vitamins, as discussed below. More specific examples of immune-modulating or anti-inflammatory ingredients that inhibit an early phase of inflammation and in specific embodiments are combined with the rice protein hydrolysates of the present disclosure to provide synergistic inflammatory benefits to a consumer include: turmeric, lutein, lycopene, zeaxanthin, luteolin, resveratrol, epigallocatechin gallate, quercetin, hydroxytyrosol (including tyrosol), astaxanthin, fisetin, conjugated linoleic acid, 6-gingerol, vitamin E, pterostilbine, pycnogenol, omega-3 fatty acids, genistein, liquiritigenin, liquiritin, ellagic acid, ursolic acid, naringenin, cocoa polyphenols, eugenol, helenalin, cinnamaldehyde, and sulphoraphane, among others.

The nutritional solids in specific embodiments are in any solid form but are typically in the form of flowable or substantially flowable particulate compositions, or at least particulate compositions. Particularly suitable nutritional solid composition forms include spray dried, agglomerated and/or dryblended powder compositions. The compositions in specific embodiments are easily be scooped and measured with a spoon or similar other device, and in specific embodiments, are easily reconstituted by the intended user with a suitable aqueous liquid, typically water, to form a nutritional composition for immediate oral or enteral use. In this context, “immediate” use generally means within about 48 hours, most typically within about 24 hours, preferably right after reconstitution.
The nutritional powders in specific embodiments are reconstituted with water prior to use to a caloric density tailored to the nutritional needs of the ultimate user. In specific embodiments the powder(s) is/are reconstituted with water to form compositions comprising at least 19 kcal/fl oz (660 kcal/liter), or from about 20 kcal/fl oz (675-680 kcal/liter) to about 25 kcal/fl oz (820 kcal/liter), or from about 20 kcal/fl oz (675-680 kcal/liter) to about 24 kcal/fl oz (800-810 kcal/liter).

The nutritional compositions in specific embodiments are alternatively in the form of solid nutritional bars and food products. For example, the nutritional compositions in specific embodiments are formulated as bars, sticks, cookies, breads, cakes, or other baked goods.
The compositions and methods of the present disclosure include at least one, and in certain embodiments, a combination of more than one rice protein hydrolysate. The rice protein hydrolysates are preferably derived from food acceptable protein sources. Particularly, it has been surprisingly found that by controlling the hydrolysis of a rice protein, the rice protein hydrolysate has anti-inflammatory properties, without adversely affecting the flavor attributes of compositions including the hydrolysate.
In certain exemplary embodiments, the nutritional compositions comprise rice protein hydrolysate as a primary or sole source of protein. The rice protein hydrolysates used in the compositions of the present disclosure have been found to show surprising anti-inflammatory properties and improved flavor and organoleptic properties as compared to other protein hydrolysates, including more extensively hydrolyzed proteins. Thus, the rice protein hydrolysates provide a good source of protein for nutritional compositions that are designed for individuals who have inflammatory conditions or diseases. These nutritional compositions further have improved flavor and emulsion stability.
In certain exemplary embodiments, the rice protein is a moderately hydrolyzed rice protein. Specific embodiments of moderately hydrolyzed rice proteins are those having a degree of hydrolysis from above 15% to 30%, or from about 16% to about 29%, or from about 17% to about 28%, or from about 18% to about 27%, or from about 20% to about 27%. In specific embodiments the moderately hydrolyzed rice protein has degree of hydrolysis from about 20% to about 25%, or about 22% to about 24%. Moderately hydrolyzed rice proteins have surprisingly demonstrated efficacy at modulating and/or reducing the late phase of the inflammatory response. This is in contrast to intact proteins which do not affect the inflammatory response in this fashion. In addition, alternative sources of moderately hydrolyzed protein (e.g., potato protein hydrolysates, certain milk-derived hydrolysates) also lack this ability to modulate a late phase of the inflammatory response. Specific embodiments of moderately hydrolyzed rice proteins are those having a degree of hydrolysis of at least 20%, or at least 25%, or at least 30%. Specific embodiments of moderately hydrolyzed rice proteins are those having a degree of hydrolysis from at least 25% to about 40%.
The rice protein hydrolysates in specific embodiments are the sole source of protein in the nutritional compositions of the present disclosure. Alternatively, additional protein sources, as described below, in specific embodiments are used in the compositions in combination with the rice protein hydrolysates to provide the total protein. Accordingly, the rice protein hydrolysate in specific embodiments provides at least 50% of the total protein by weight in the nutritional composition, or from about 50% to about 100% of the total protein, or from about 60% to about 95% of the total protein, or from about 70% to about 90% of the total protein, or from about 75% to about 85% of the total protein in the nutritional composition. As noted herein, the additional protein sources in specific embodiments include partially hydrolyzed, hydrolyzed, unhydrolyzed (intact) proteins, and/or a combination thereof. Rice protein hydrolysate in specific embodiments provides from about 0.15% to about 1.5% of the total protein by weight in the nutritional composition. In specific embodiments 3.6% by weight of the product is protein, and 1.8% of the total weight of the product is from rice protein hydrolysate. In specific embodiments from about 1.8% to about 5% of the product by weight is rice protein hydrolysate, or from about 1.5% to about 6%.
In specific embodiments brown rice is moderately hydrolyzed. In specific embodiments nutritional compositions for modulating or reducing inflammation in an individual contain hydrolyzed rice proteins derived from brown rice.
In addition to the rice protein hydrolysates described above, specific embodiments of the nutritional compositions of the present disclosure include LCPUFAs. LCPUFAs are included in the nutritional compositions to provide nutritional support, as well as to reduce oxidative stress and enhance growth and functional development of a variety of biological and immune functions.

Polyphenols are included in the nutritional compositions to provide nutritional support, as well as to enhance growth and functional development of a variety of biological and immune functions. In some embodiments, the nutritional composition includes a combination of rice protein hydrolysates and polyphenols such that the composition provides a synergistic benefit to the end user, such as a synergistic benefit in modulating or dampening inflammation.
Polyphenols, as used herein, are a structural class of mainly natural, but also synthetic or semi-synthetic, organic chemicals characterized by the presence of large multiples of phenol structural units. In particular, the term polyphenol refers to biologically active phytochemicals, such as those that arise in wine, tea, and, for example, the extracts of certain fruits.
In addition to the rice protein hydrolysates described above, the nutritional compositions of the present disclosure in specific embodiments include curcuminoids. Curcuminoids are included in the nutritional compositions to provide nutritional support, as well as to reduce inflammation and enhance growth and functional development of a variety of biological and immune functions. In some embodiments, the nutritional composition includes a combination of rice protein hydrolysates and curcuminoids such that the composition provides a synergistic benefit to the end user, such as a synergistic benefit in modulating or dampening inflammation.
Curcumin is the principal curcuminoid found in turmeric and is responsible for the yellow color of the spice. The term “curcuminoid,” as used herein, refers to curcumin and derivatives thereof and analogs thereof. These include natural and synthetic derivatives of curcumin, and any combination of more than one curcuminoid. In particular, for the purposes herein, the term “curcuminoid” should be understood to encompass compounds having a 1,7-bis (4-hydroxyphenyl)-1,6-heptadiene-3,5-dione or 1,7-bis(4-hydroxyphenyl)hept-4-en-3-one skeleton wherein the phenyl groups independently in specific embodiments bear one or more alkoxy residues, and in specific embodiments have one methoxy residue in the 3-position.
Specific naturally occurring curcuminoids comprise curcumin (1,7-Bis-(4-hydroxy-3-methoxyphenyl)-hepta-1,6-diene-3,5-dione), desmethoxycurcumin (1-(4-Hydroxyphenyl)-7-(4-hydroxy-3-methoxyphenyl)-hepta-1,6-diene-3,5-dione) and bis-desmethoxycurcumin (1,7-Bis-(4-hydroxyphenyl)-hepta-1,6-di ene-3,5-dione).

Many such techniques are known for any given product form such as nutritional liquids or powders and in specific embodiments are easily applied by one of ordinary skill in the art to the nutritional compositions described herein.
The nutritional compositions of the present disclosure are in specific embodiments prepared by any of a variety of known or otherwise effective formulation or manufacturing methods. In one suitable manufacturing process, for example, at least three separate slurries are prepared, including a protein-in-fat (PIF) slurry, a carbohydrate-mineral (CHO-MIN) slurry, and a protein-in-water (PIW) slurry. The PIF slurry is formed by heating and mixing the oil (e.g., canola oil, corn oil, etc.) and then adding an emulsifier (e.g., lecithin), fat soluble vitamins, and a portion of the total protein (e.g., rice protein hydrolysate, etc.) with continued heat and agitation. The CHO-MIN slurry is formed by adding with heated agitation to water: minerals (e.g., potassium citrate, dipotassium phosphate, sodium citrate, etc.), trace and ultra trace minerals (TM/UTM premix), thickening or suspending agents (e.g. avicel, gellan, carrageenan). The resulting CHO-MIN slurry is held for 10 minutes with continued heat and agitation before adding additional minerals (e.g., potassium chloride, magnesium carbonate, potassium iodide, etc.), and/or carbohydrates (e.g., HMOs, fructooligosaccharide, sucrose, corn syrup, etc.). The PIW slurry is then formed by mixing with heat and agitation the remaining protein, if any.
The resulting slurries are then blended together with heated agitation and the pH adjusted to 6.6-7.0, after which the composition is subjected to high-temperature short-time (HTST) processing during which the composition is heat treated, emulsified and homogenized, and then allowed to cool. Water soluble vitamins and ascorbic acid are added, the pH is adjusted to the desired range if necessary, flavors are added, and water is added to achieve the desired total solid level. The composition is then aseptically packaged to form an aseptically packaged nutritional emulsion. This emulsion in specific embodiments may then alternatively be further diluted, heat-treated, and packaged to form a ready-to-feed or concentrated liquid. Alternatively, the product may be produced by first making a base powder and subsequently adding the hydrolyzed rise protein via drymixing techniques to produce the final product for packaging.
The nutritional solid, such as a spray dried nutritional powder or drymixed nutritional powder, in specific embodiments is prepared by any collection of known or otherwise effective technique, suitable for making and formulating a nutritional powder. Drying methods may also include rotating drum drying, fluid bed drying, belt drying technologies, and so forth.
For example, when the nutritional powder is a spray dried nutritional powder, the spray drying step in specific embodiments likewise includes any spray drying technique that is known for or otherwise suitable for use in the production of nutritional powders. Many different spray drying methods and techniques are known for use in the nutrition field, all of which are suitable for use in the manufacture of the spray dried nutritional powders herein.
One method of preparing the spray dried nutritional powder comprises forming and homogenizing an aqueous slurry or liquid comprising predigested fat, and optionally protein, carbohydrate, and other sources of fat, and then spray drying the slurry or liquid to produce a spray dried nutritional powder. The method in specific embodiments further comprises the step of spray drying, drymixing, or otherwise adding additional nutritional ingredients, including any one or more of the ingredients described herein, to the spray dried nutritional powder.
The nutritional compositions as described herein in specific embodiments is used to address one or more of the diseases or conditions discussed herein, or in specific embodiments is used to provide one or more of the benefits described herein. The individual utilizing the nutritional compositions described herein in specific embodiments actually is afflicted with the disease or condition described, or may be susceptible to, or at risk of, getting the disease or condition (that is, may not actually yet have the disease or condition, but is at elevated risk as compared to the general population for getting it due to certain conditions, family history, etc.) Whether the individual actually has the disease or condition, or is at risk or susceptible to the disease or condition, the individual is classified herein as “in need of” assistance in preventing dealing with and combating the disease or condition. For example, the individual in specific embodiments actually has an inflammatory disease or may be at risk of getting inflammatory disease due to family history or other medical conditions, for example.
Based on the foregoing, because some of the method embodiments of the present disclosure are directed to specific subsets or subclasses of identified individuals (that is, the subset or subclass of individuals “in need” of assistance in addressing one or more specific diseases or specific conditions noted herein), not all individuals will fall within the subset or subclass of individuals as described herein for certain diseases or conditions.
The following examples illustrate specific embodiments and/or features of the nutritional compositions of the present disclosure. The examples are given solely for the purpose of illustration and are not to be construed as limitations of the present disclosure, as many variations thereof are possible without departing from the spirit and scope of the disclosure.
In vitro experiments have been performed to study the effect of two forms of rice protein hydrolysate (RPH-1 and RPH-2) on murine cells.
Table 3 provides a comparison of three groups: intact rice protein (Oryzatein SG-B, RPH-1 (Oryzatein SG-B/N # RP35312) and RPH-2 (Oryzatein SG-B/N # BNB15215-0). RPH-1 and RPH-2 are two manufactured lots of Axiom Foods Organic Oryzatein® hydrolyzed rice protein. These two lots of Oryzatein SG-B/N rice protein hydrolysate were tested for loss on drying, amino nitrogen (by TNBS colorimetry), and for molecular weight (MW) profile. A single lot of Oryzatein Silk 80 rice protein concentrate was also tested for loss on drying and for amino nitrogen. The MW profile data refers to the soluble protein only (much of the Oryzatein SG-B/N protein is insoluble in water). Solubility was calculated as the average solubility obtained by two different methods: (a) size exclusion chromatography and (b) amino acid analysis of the soluble component versus the whole hydrolysate. The method used follows a published method (Food Chem, 125 [2011] 1041-1050).

11%
Table 4 shows a replicate experiment of results of Table 3, showing another comparison of two manufactured lots of Axiom Foods Organic Oryzatein® hydrolyzed rice protein (RPH-1 and RPH-2). Each was tested for MW profile by the published method (Food Chem, 125 [2011] 1041-1050). The MW profiles in Table 3 and Table 4 were determined for the same two lots of the rice hydrolysate. The MW median averages of Tables 3 and 4 are RPH-1=1552 Daltons and RPH-2=2396 Daltons, and the corresponding DH values would (still) be RPH-1=15% and RPH-2=11%.
As shown in Table 3 and Table 4, RPH-1 has a higher amount of smaller peptides (<500 and 500-1000 Da) and a lower amount of larger peptides (3000-5000 and >5000 Da) versus RPH-2. This is consistent with the fact that RPH-1 has a higher degree of hydrolysis (15%) versus 11% for RPH-2. This higher degree of hydrolysis translates into more peptide bonds being cleaved resulting in a greater number of smaller peptides. Therefore active components of RPH-1 likely reside within this smaller peptide mix. In specific embodiments at least 30%° of the rice protein hydrolysate peptides are less than 1000 Da. In specific embodiments the rice protein hydrolysate comprises from about 30% to about 50% of peptides that are less than 1000 Da, or from about 30 to about 40%, or from about 33-38%. In specific embodiments at least 14% of the rice protein hydrolysate peptides are less than 500 Da. In specific embodiments the rice protein hydrolysate comprises from about 12% to about 30% of peptides that are less than 500 Da, or from about 14% to about 25%, or from about 14% to about 18%, or from about 15% to about 17%.
Specific studies have determined effects of the hydrolysates on TNFα secretion, 4-1BBL expression, and NF-κB Expression in murine macrophages (RAW 264.7 cells) treated with LPS (see
RPH-1 inhibits early and late phase TNFα secretion from cells in culture.
Pretreatment with RPH-2 for 1 hour did not affect LPS-induced TNFα secretion from cells at 6 hours (
Pretreatment with curcumin at 0.5 μg/mL and 1.0 g/mL for 1 hour led to an inhibition of TNFα secretion (
In additional experiments, RPH-1 preincubation also resulted in a statistically significant decrease in 4-1BBL expression 24 hours after treatment when applied at levels from 100-1000 micrograms (
Animal experiments demonstrated that 1 hour pretreatment with RPH-1 (2.5 mg/kg) decreased LPS-induced (1.5 mg/kg i.p.) median levels of TNFα in plasma in mice (
