CROSS-REFERENCE TO RELATED APPLICATIONS
[0001] This application claims the benefit of priority to U.S. Provisional Patent Application Serial No. 63 / 336,622, filed on April 29, 2022, which is incorporated herein by reference in its entirety. background
[0002] A. Field of the Invention
[0003] The present invention relates generally to the field of topical skin compositions. More specifically, the present invention relates to the use of topical skin compositions for reducing skin irritation caused by activation of transient receptor potential channel vanilloid subtype 1 (TRPV-1) agonists (eg, retinol activation).
[0004] B. Related technical description
[0005] Aging, chronic exposure to adverse environmental factors, malnutrition, fatigue, etc. can alter the visual appearance, physical properties, or physiological functions of the skin in visually undesirable ways. The most significant and obvious changes include the appearance of fine lines and wrinkles, loss of elasticity, increased sagging, decreased firmness, loss of color uniformity or tone, rough surface texture, and mottled pigmentation. As the skin ages or is subjected to chronic environmental insults, the skin undergoes subtle but measurable changes, including a general decrease in cell and tissue viability, reduced cell replication rates, decreased skin blood flow, decreased water content, accumulation of structural and functional errors, alterations in the normal regulation of common biochemical pathways, and a decrease in the skin's ability to remodel and repair itself. Many changes in the skin's appearance and function are caused by changes in the outer epidermal layer of the skin, while others are caused by changes in the dermis.
[0006] Previous attempts to improve the visual appearance of the skin using known skin active ingredients have been shown to have various disadvantages, such as skin irritation and prolonged recovery period. Retinol (vitamin A) is one of the first FDA-approved anti-aging therapeutics, which is used in cosmetic preparations for treating skin photodamage and delaying aging. Retinol binds to different receptors to regulate various cellular processes, such as, but not limited to, keratinocyte differentiation, blocking the transport of melanin to epidermal cells, inhibiting matrix metalloproteinases (MMPs), and / or stimulating the synthesis of collagen fibers in fibroblasts. (M Zasada et al.; 2019). In addition, retinol can also increase the excitability of nociceptors (sensory neurons), and this increase in excitability can lead to increased tissue sensitivity and / or irritation. Irritation caused by retinoids is the main reason why subjects do not comply with the treatment regimen and / or stop using retinol before improving the appearance of the skin. In addition, excessive use of retinol can also exacerbate skin dryness and / or burning sensations. Published literature describes that up to 12% of subjects reported adverse events (AEs) when using retinol. Skin inflammation may be a direct response to noxious chemosensory stimuli. Certain cells, such as epidermal keratinocytes, melanocytes, and / or fibroblasts, may also release cytokines in response to noxious stimuli, which, in addition to other inflammatory effects, can sensitize peripheral nociceptive fibers and produce neurogenic inflammation. Previous studies have shown that retinol activates transient receptor potential channel vanilloid subtype 1 (TRPV-1), which is a stimulatory receptor for capsaicin (S Yin et al.; 2013).
[0007] It is shown herein that a combination of one or more TRPV-1 antagonists (e.g., saccharide isomers, pumpkin seed extract, common reed extract, and / or China root extract) can be used to inhibit TRPV-1 mediated calcium flux and related tissue irritation, such as irritation caused by anti-aging compounds (e.g., irritation caused by retinoids). In addition, the inventors show that such TRPV-1 antagonists can be optionally combined with one or more pro-inflammatory cytokine inhibitors, and / or optionally combined with one or more anti-aging compound tolerance improvement regimens to further increase an individual's tolerance to a treatment regimen that includes irritating anti-aging compounds (e.g., hydroquinone, resorcinol, trichloroacetic acid, carboxylic acids, dicarboxylic acids, beta-hydroxy acids, and / or alpha-hydroxy acids).

[0072] As described above, in certain embodiments, the present invention provides solutions to problems associated with current cosmetic products. In some embodiments, an effective amount of plankton extract (saccharide isomers), Phragmites australis (common reed) extract, Poria cocos (root smilax) extract and / or Cucurbita pekinensis (pumpkin) seed extract is used to inhibit TRPV-1-mediated calcium flux, thereby reducing adverse events, reducing unwanted side effects and / or increasing subject compliance with treatment regimens. Compositions comprising an effective amount of plankton extract (saccharide isomers), Phragmites australis (common reed) extract, Poria cocos (root smilax) extract and / or Cucurbita pekinensis (pumpkin) seed extract can be used to reduce fine lines and wrinkles, even out skin tone, brighten skin tone, increase skin radiance, reduce photodamage, increase elasticity, increase skin barrier function, increase skin firmness, reduce skin sagging, and are superior to those comprising larger amounts of anti-aging compounds (e.g., alpha-hydroxy acids, retinol, etc.).
[0073] In some embodiments, disclosed herein are compositions and methods for inhibiting cellular calcium flux, reducing the release of cell signaling molecules and / or the compliance of an object to a cosmetic treatment regimen. In certain embodiments, the compositions and methods disclosed herein reduce, inhibit and / or substantially eliminate responses to harmful chemical sensory stimuli (e.g., α-hydroxy acids, retinol, etc.). In certain embodiments, this inhibition results in the alleviation of stimulated tissues, the reduction of tissue inflammation, the reduction of tissue redness and / or the reduction of dry skin. In certain embodiments, the compositions and / or methods disclosed herein improve the visual appearance of the skin. In certain embodiments, the compositions and / or methods disclosed herein improve the compliance of an object to a treatment regimen recommended by a clinician and / or manufacturer. In certain embodiments, the compositions and / or methods disclosed herein reduce discomfort, erythema and / or dry skin. In certain aspects, the compositions disclosed herein and methods of use thereof may include, but are not limited to, combinations of ingredients for exfoliating the skin, reducing or eliminating exfoliation irritation, reducing and / or eliminating the appearance of fine lines and / or wrinkles, renewing the skin, increasing skin radiance, soothing the skin, soothing tissue, reducing and / or eliminating inflammation, even skin tone, reducing the appearance of hyperpigmented skin, age spots, liver spots, and / or dark spots, and / or increasing skin smoothness. In certain embodiments, the compositions and / or methods described herein reduce unwanted side effects, reduce adverse events, and / or increase subject compliance with a treatment regimen.
[0074] As shown in Table 2 and Figure 2 As shown, each of the plankton extract (saccharide isomers), Phragmites australis (common reed) extract, Poria cocos (Smilax glabra) root extract, and / or Cucurbita pekinensis (Pumpkin) seed extract showed inhibition of TRPV-1 mediated calcium influx. Figure 3 and Figure 4 As shown, administration of a composition comprising a TRPV-1 inhibitor improves skin characteristics described by subjects and dermatologists, such as skin hyperpigmentation, overall fine lines and wrinkles, skin tone evenness, overall photodamage, skin firmness, erythema, dryness, and / or edema.
[0075] In some embodiments, the composition comprising plankton extract (saccharide isomers), Phragmites australis (common reed) extract, Poria cocos (Smilax glabra root) extract and / or Cucurbita pekinensis (Pumpkin) seed extract can be designed as an emulsion (e.g., oil-in-water, water-in-oil), a gel, a serum, a gel emulsion, a gel serum, a lotion, a mask, a scrub, a wash, a cream, a facial cleanser, a sunscreen, a cleanser, a day cream, a night cream, a body lotion, other skin treatment products, or any combination thereof.
[0076] Some compositions disclosed herein can be applied to the skin or hair and remain on the skin or hair for a period of time (e.g., at least 1 minute, 2 minutes, 3 minutes, 4 minutes, 5 minutes, 10 minutes, 20 minutes, 30 minutes, or 60 minutes or longer). Thereafter, the composition can be rinsed from the skin or peeled from the skin if desired. Some compositions disclosed herein can be applied to the skin and immediately rinsed from the skin. Some compositions disclosed herein can be applied to the skin and at least partially absorbed by the skin.
[0077] Herein, the inventors show that the addition of one or more than one TRPV-1 antagonist to a cosmetic formulation containing an anti-aging compound (e.g., 0.5% retinol) results in improved compliance with the subject's treatment regimen and reduced erythema, edema, and dryness as assessed by a dermatologist. Retinoids have been widely used to treat photoaging, many of which have shown significant clinical improvements. Although retinoids are the gold standard for treating skin aging, reactions associated with their use, such as burning and peeling, are the main reasons for non-compliance or discontinuation. The retinalization process described herein improves the subject's retinol tolerance by preventing irritation, allowing the subject to comply throughout the study. In addition, the inventors show that less than 6% of the subjects tested for the retinalization regimen reported adverse events during the study, indicating that a combination of TRPV-1 antagonists, nociceptor antagonists, and / or gradual retinalization processes may be a particularly beneficial component in a successful composition and / or method that involves combating signs of aging, particularly by improving tolerance and alleviating irritation caused by anti-aging compounds. In some embodiments, the methods provided herein comprise, consist essentially of, or consist of a TRPV-1 antagonist, a nociceptor antagonist, and / or a combination for combating the gradual retinalization process of signs of aging, particularly by improving tolerability and reducing irritation caused by anti-aging compounds (e.g., irritation caused by retinol, etc.).
[0078] In summary, the studies described herein indicate that the TRPV-1 antagonists described herein can be used to mitigate the irritation associated with the use of high doses of anti-aging compounds (e.g., alpha-hydroxy acids, retinol, etc.) These and other non-limiting aspects of the invention will be described in the following sections.
[0079] A. Active ingredients
[0080] Saccharide isomers are exopolysaccharides that can be synthesized by a microorganism called Vibrio alginolyticus, which belongs to the marine plankton family. In some cases, this ingredient is called a plankton extract. In some cases, this ingredient can be purchased from Barnet Products, which supplies saccharide isomers under the trade name Benoiderm™. In some cases, this ingredient can be purchased under the trade name Benoitine™, also supplied by Barnet Products. It has been determined that an effective amount of saccharide isomers can be used to inhibit TNFα. It is shown herein that an effective amount of saccharide isomers can be used to inhibit TRPV-1 mediated calcium flux.
[0081] Phragmites australis, commonly known as "common reed", but also known as "perennial reed", "ditch reed", "giant reed", "reed grass" or "phragmites". It is a tall, robust perennial herb commonly found in wetlands, swamps, riverbanks and lakesides. Common reed has traditionally been used to improve symptoms associated with indigestion, diabetes, leukemia, breast cancer and insect bites. Common reed is known to contain vitamin A, vitamin C and some B vitamins, but to our knowledge, the potential pathogenic components or mechanisms of action have not been publicly described. It is shown herein that an effective amount of a reed extract can be used to inhibit TRPV-1 mediated calcium flux. In some cases, this ingredient is used in combination with a Poria cocos extract, which is marketed by Chemisches Laboratorium (CLR) under the trade name "SyriCalm"™.
[0082] Poria cocos is a saprophytic fungus of the Polyporaceae family, commonly known as "China root", but also known as "bracket fungus", "Fu-ling", "Hoelen", "Indian Bread", "Tuckahoe", "clerotium cocos", "Wolfiporia extensa", "Wolfiporia cocos", "Daedalea extensa", "Macrohyporia extensa", "Macrohyporia cocos", "Pachyma cocos" or "Medicine of Immortality". Poria cocos grows in and / or on various pine trees, and its sclerotia (vegetative dormant spores) (called "Fuling" in Chinese) have been used as a traditional Chinese medicine for more than two thousand years. Poria cocos has a wide range of biological activities, including anti-tumor, immunomodulatory, anti-inflammatory, antioxidant, anti-aging, anti-hepatitis, anti-diabetic and anti-hemorrhagic fever effects. Poria polysaccharide (PCP) accounts for 84% by weight of all components in the dried sclerotia and is considered to be the main bioactive component. It is shown herein that an effective amount of Poria cocos extract can be used to inhibit TRPV-1 mediated calcium flux. In some cases, this ingredient can be used in combination with a reed extract, which is marketed by Chemisches Laboratorium (CLR) under the trade name "SyriCalm"™.
[0083] Cucurbita pekinensis (Pumpkin) seeds are derived from the Cucurbita pekinensis subsp. Cucurbita pekinensis. Cucurbita pekinensis seed extract has a variety of bioactive compounds with potential nutritional and / or medicinal properties. The beneficial properties of pumpkin seed extract may be due to its strongly dichroic viscous oil. Pumpkin has been used as a treatment option for hypertension and carcinogenic diseases, as an antidiabetic, antibacterial, antioxidant and / or anti-inflammatory agent. It is shown herein that an effective amount of Cucurbita pekinensis seed extract can be used to inhibit TRPV-1 mediated calcium flux. In some cases, such Cucurbita pekinensis (Pumpkin) seed extract is commercially available from Givaudan Active Beauty under the trade name "Ocâline"™.
[0084] The present invention is based on the determination that any one, any combination or all of plankton extract (saccharide isomers), Phragmites australis (common reed) extract, Poria cocos (Smilax glabra) extract and / or Cucurbita pekinensis (Pumpkin) seed extract can be used to inhibit TRPV-1 mediated calcium flux. In some embodiments, inhibiting TRPV-1 mediated calcium flux can relieve skin irritation, reduce skin inflammation, reduce skin redness and / or reduce skin dryness.
[0085] The ingredients disclosed herein can be used in combination with various other cosmetically suitable ingredients, and / or can be used in different product forms to treat various skin diseases. As non-limiting examples, the combination of ingredients can be formulated into an emulsion (e.g., oil-in-water, water-in-oil), a gel, an essence, a gel emulsion, a gel essence, an emulsion, a facial mask, a scrub, a lotion, a cream, or a body lotion.
[0086] The extracts described herein may be extracts prepared by extraction methods and combinations thereof known in the art. Non-limiting examples of extraction methods include the use of liquid-liquid extraction, solid phase extraction, solution extraction, ethyl acetate, ethanol, acetone, oil, supercritical carbon dioxide, heat, pressure, pressure drop extraction, ultrasonic extraction, etc. The extract may be a liquid, a solid, a dried liquid, a resuspended solid, etc.

[0167] It has been determined that any of the plankton extract (saccharide isomers), Phragmites australis (common reed) extract, Poria cocos (Smilax glabra) root extract, and / or Cucurbita pekinensis (Pumpkin) seed extract can be used to inhibit TRPV-1 mediated calcium flux. The results are summarized in Table 2, and the methods used to determine the properties of the ingredients are provided below.
[0168] The ability of the component samples to inhibit calcium flux generation in PC 12 cells (ATCC CRL-1721) was analyzed. PC 12 cells were maintained and passaged according to the manufacturer's recommended instructions. For the experiments, 1×10 5 Cells / well were seeded in a 96-well black flat-bottom plate. Fura-2-acetoxymethyl ester (Fura-2AM) calcium detection assay kit (Cayman Chemical #14591) was used to detect calcium in the treated cells. Capsaicin (Sigma # M202) was used to initiate the reaction, and capsaicin (Sigma # C191) was used as a positive control. In brief, Ca 2+ Inward flux is used as a measure of TRPV-1 activity. PC 12 cells (ATCC CRL-1721) were pre-incubated with the corresponding test compounds at 37°C for 4 hours. After pre-incubation, the treatment medium was removed and the cells were incubated with 100 μL 0.67 μM Fura-2AM at 37°C for 1 hour. After incubation, the cells were treated with 200 μM capsaicin to induce TRPV-1-mediated Ca2+ flux response, and fluorescence readings were read every 7 seconds at 360 / 460 nm for 10 minutes. After the test period, the buffer was removed and 100 μL of diluted MTS reagent was added to each well. The cells were incubated at 37°C under 5% CO2 for 15 to 30 minutes, and the plate readings were read at 490 nm. Cell viability was assessed before analyzing calcium flux.
[0169] Fluorescence test data were normalized to controls to generate area under the curve (AUC) values. For each control and test, the fluorescence arbitrary units (AU) were normalized to the controls at time points 0 min and 0.5 min to 9 min. The normalized data were plotted on an XY graph using GraphPad Prism software to generate a calcium flux curve with time on the X axis and normalized AU on the Y axis. The AUC for the untreated control was then calculated, and the net AUC for each test and control condition was determined. The data for the test conditions are expressed as a percentage of the positive control (capsazepine 400µM) (results are shown in Table 2).
[0170] Cells pre-incubated with plankton extracts (e.g., Saccharide isomers, also known as Benoitine), Phragmites australis (common reed) extracts, and Poria cocos (Smilax glabra) root extracts (e.g., Syricalm™), and Cucurbita pekinensis (pumpkin) seed extracts (e.g., Ocâline™ PF), respectively, showed similar Ca2+ levels to cells incubated with the positive control Capsicum annuum. 2+ Flux curve, where Ca 2+ The flux increased but decreased within 2 or 4 minutes, respectively.

[0178] Example 4
[0179] (Additional determination)
[0180] Assays that can be used to determine the efficacy of any ingredient, or any combination of ingredients or compositions disclosed throughout this specification and claims comprising a combination of ingredients can be determined by methods known to those of ordinary skill in the art. The following are non-limiting assays that can be used in the context of the present invention. It should be appreciated that other testing procedures can be used, including, for example, objective and subjective procedures.
[0181] B16 Pigmentation Assay: Melanogenesis is the process by which melanocytes produce melanin, a naturally occurring pigment that gives color to the skin, hair, and eyes. Inhibition of melanogenesis is beneficial in preventing skin darkening and reducing dark spots associated with aging. This bioassay uses an immortalized mouse melanoma cell line, B16-F1 melanocytes (ATCC), to analyze the effects of compounds on melanin production. The endpoints of this analysis are spectrophotometric measurements of melanin production and cell activity. B16-F1 melanocytes can be cultured in standard DMEM growth medium with 10% fetal bovine serum (MEDIATECH) at 37°C in 10% CO2 and then treated with any of the active ingredients, combinations of ingredients, or compositions having said combinations disclosed in this specification. After incubation, cell activity is quantified by measuring melanin secretion by absorption at 405nm.
[0182] Collagen stimulation assay: Collagen is an extracellular matrix protein that is very important for the structure of the skin. Increased collagen synthesis helps improve skin firmness and elasticity. This bioassay can be used to detect the effect of any of the active ingredients, combinations of ingredients, or compositions having said combinations disclosed in this specification on the production of procollagen peptides (precursors of collagen) by human epidermal fibroblasts. The endpoint of this test is a spectrophotometric measurement reflecting the presence of procollagen peptides and cell activity. The analysis uses a quantitative sandwich enzyme immunoassay technique, so monoclonal antibodies specific for procollagen peptides are pre-coated on microplates. Standards and samples can be pipetted into the wells, and all procollagen peptides present are bound by the immobilized antibodies. After washing away all unbound material, an enzyme-linked polyclonal antibody specific for procollagen peptides is added to the wells. After rinsing to remove all unbound antibody-enzyme reactants, a substrate solution can be added to the wells, and the color development is proportional to the amount of procollagen peptide bound in the initial step, and is detected at 450nm using a microplate reader. The color development can be stopped and the intensity of the color measured.
[0183] To generate samples and controls, subconfluent normal human mature epidermal fibroblasts (Cascade Biologics) cultured in standard DMEM growth medium with 10% fetal bovine serum (MEDIATECH) at 37° C. in 10% CO 2 can be treated with each of the combinations of components disclosed in the specification or compositions having said combinations for 3 days. After incubation, the cell culture medium can be collected, and the amount of procollagen peptide secretion can be quantified using TAKARA's sandwich enzyme-linked immunosorbent assay (ELISA) (#MK101).
[0184] Elastin Stimulation Assay: Elastin is a connective tissue protein that helps the skin regain its shape after being stretched or contracted. Elastin is also an important load-bearing protein used where mechanical energy needs to be stored. Elastin is made by joining many soluble tropoelastin molecules in a reaction catalyzed by the enzyme lysyl oxidase. Elastin secretion and elastin fibers can be monitored in cultured human fibroblasts by staining them with an immunofluorescent antibody against elastin.
[0185] Laminin and Fibronectin Stimulation Assay: Laminin and Fibronectin are the major proteins in the dermal-epidermal junction (DEJ), also known as the basement membrane. The DEJ is located between the dermis and the epidermis and interlocks to form finger-like projections, called reticular ridges. Epidermal cells receive their nutrients from blood vessels in the dermis. The reticular ridges increase the surface area of the epidermis exposed to these blood vessels and required nutrients. The DEJ provides adhesion of the two tissue compartments and controls the structural integrity of the skin. Laminin and Fibronectin are two glycoproteins located in the DEJ. Laminin and Fibronectin are considered to be adhesives that glue cells together and are secreted by dermal fibroblasts to help promote intracellular and intercellular adhesion of the epidermis called DEJ. The secretion of laminin and fibronectin can be monitored by quantifying laminin and fibronectin in the cell supernatant of cultured human fibroblasts treated for 3 days with medium containing or not containing 1.0% final concentration of the test component. After incubation, the content of laminin and fibronectin can be measured in an enzyme-linked immunosorbent assay (ELISA) using immunofluorescent antibodies against laminin and antibodies against fibronectin. The measurement of cellular metabolic activity is normalized as determined by the bioconversion of 3-(4,5-dimethylthiazol-2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulfophenyl)-2H-tetrazole (MTS).
[0186] Tumor Necrosis Factor Alpha (TNF-α) Assay: TNF-α, the prototype ligand of the TNF superfamily, is a pleiotropic cytokine that plays a major role in inflammation. Increased expression of it is associated with upregulated proinflammatory activity. This bioassay can be used to detect the effect of any of the active ingredients, combinations of ingredients, or compositions having said combinations disclosed in this specification on the production of TNF-α by human epidermal keratinocytes. The endpoint of the assay may be a spectrophotometric measurement reflecting the presence of TNF-α and cell activity. The assay uses a quantitative sandwich enzyme immunoassay technique, so a monoclonal antibody specific for TNF-α has been pre-coated on a microplate. Standards and samples can be pipetted into the wells, and any TNF-α present is bound by the immobilized antibody. After washing away all unbound material, an enzyme-linked polyclonal antibody specific for TNF-α can be added to the wells. After washing to remove all unbound antibody-enzyme reactants, a substrate solution can be added to the wells, and color development is proportional to the amount of TNF-α bound in the initial step, detected at 450 nm using a microplate reader. The color development can be stopped and the intensity of the color can be measured. Subconfluent normal adult keratinocytes (Cascade Biologics) cultured in EPILIFETM standard growth medium (Cascade Biologics) at 37°C in 5% CO2 can be treated with phorbol 12-myristic acid 13-acetate (PMA, 10ng / mL, SIGMA CHEMICAL, #P1585-1MG) and any of the active ingredients disclosed in the specification, ingredient combinations, or compositions with the combination for 6 hours. PMA has been shown to cause a significant increase in TNF-α secretion, which peaks 6 hours after treatment. After cultivation, cell culture media can be collected and the amount of TNF-α secretion can be quantified using a sandwich enzyme-linked immunosorbent assay (ELISA) from R&D Systems (#DTA00C).
[0187] Antioxidant (AO) assay: An in vitro bioassay that measures the total antioxidant capacity of any of the ingredients, combinations of ingredients, or compositions having said combinations disclosed herein. The assay relies on the ability of antioxidants in a sample to inhibit the ABTS ® (2,2'-Azobis-[3-ethylbenzothiazoline sulfonate]) is oxidized to ABTS by metmyoglobin ®+. The antioxidant system of living organisms contains enzymes such as superoxide dismutase, catalase and glutathione peroxidase; macromolecules such as albumin, ceruloplasmin and ferritin; and a large number of small molecules, including ascorbic acid, α-tocopherol, β-carotene, reduced glutathione, uric acid and bilirubin. The total number of endogenous food-derived antioxidants represents the total antioxidant capacity of the extracellular fluid. The collaboration of all different antioxidants provides stronger protection against the attack of reactive oxygen or nitrogen free radicals than any single compound alone. Therefore, the total antioxidant capacity can give more relevant biological information than that obtained by measuring individual components because it takes into account the cumulative effect of all antioxidants present in plasma and body fluids. The ability of antioxidants in the sample to prevent ABTS oxidation was compared with Trolox, a water-soluble tocopherol analog, and quantified as the molar equivalent of Trolox. As an in vitro bioassay for measuring the total antioxidant capacity of any of the ingredients, combinations of ingredients, or compositions having said combinations disclosed in this specification, the antioxidant capacity kit # 709001 from CAYMAN CHEMICAL (Ann Arbor, Michigan USA) can be used. The protocol can be performed according to the manufacturer's recommendations.

Antioxidant activity indicates the ability to reduce oxidants (oxidants). This analysis quantifies the time and degree required to inhibit the action of oxidants, such as oxygen free radicals, which are known to cause damage to cells (such as skin cells). The ORAC value of any of the active ingredients disclosed in this specification, the combination of active ingredients, or the composition containing the combination can be determined by methods known to those of ordinary skill in the art (see US Publication Nos. 2004 / 0109905 and 2005 / 0163880; and commercially available kits such as Zen-Bio ORAC Antioxidant Assay Kit (#AOX-2)). The Zen-Bio ORAC Antioxidant Assay Kit measures the loss of fluorescein fluorescence over time due to the formation of hydroperoxide-free radicals by the decomposition of AAPH (2,2'-azobis-2-methylpropylimidazole dihydrochloride). Trolox is a water-soluble vitamin E analog used as a positive control that inhibits fluorescein decay in a dose-dependent manner.
[0189] Mushroom tyrosinase activity assay: In mammalian cells, tyrosinase catalyzes two steps in the biosynthesis of melanin from tyrosine (and from dopachrome polymerization). Tyrosinase is located in melanocytes and produces melanin (aromatic quinone compound) that gives skin, hair and eyes color. Mushroom tyrosinase (SIGMA) can be cultured with its substrate L-Dopa (FISHER) in the presence or absence of any of the active ingredients disclosed in this specification, the combination of ingredients, or the combination having said combination. Pigment formation can be assessed by colorimetric plate reading at 490nm. The percentage inhibition of mushroom tyrosinase activity can be calculated by comparison with an untreated control to determine the ability of the test ingredient or its combination to inhibit the activity of the purified enzyme. The inhibitory effect of the test extract was compared with the inhibitory effect of kojic acid (SIGMA).
[0190] Matrix metalloproteinase 3 and matrix metalloproteinase 9 activity (MMP3; MMP9) assay: In vitro matrix metalloproteinase (MMP) inhibition assay. MMPs are extracellular proteases that play a role in many normal and disease states by virtue of their broad substrate specificity. MMP3 substrates include collagen, fibronectin, and laminin; whereas MMP9 substrates include collagen VII, fibronectin, and laminin. Using colorimetric drug discovery kits for MMP3 (AK-400) and MMP-9 (AK-410) from BioMol International, the assay is designed to measure the protease activity of MMPs using a sulfur-containing polypeptide as a chromogenic substrate (Ac-PLG-[2-mercapto-4-methyl-pentanoyl]-LG-OC2H5)5,6. The peptide bond of the MMP cleavage site is replaced by a thioester bond in the sulfur-containing polypeptide. This bond is hydrolyzed by MMP to generate a thiol group, which reacts with DTNB [5,5'-dithiobis(2-nitrobenzoic acid), Ellman's reagent] to generate 2-nitro-5-thiobenzoic acid, which can be detected by its absorbance at 412 nm (ε = 13600 M-1cm at pH 6.0 and above 7). -1 ). Any of the active ingredients, ingredient combinations disclosed in this specification, or compositions containing the combinations may be tested.
[0191] Matrix Metalloproteinase 1 Enzyme Activity (MMP1) Assay: In vitro matrix metalloproteinase (MMP) inhibition assay. MMPs are extracellular proteases that play a role in many normal and disease states by virtue of their broad substrate specificity. MMP1 substrates include collagen IV. The Molecular Probes ENZ / CHEK Gelatinase / Collagenase Assay Kit (#E12055) utilizes a fluorescent gelatin substrate to detect MMP1 protease activity. After proteolytic cleavage, bright green fluorescence is displayed and can be observed using a fluorescent microplate reader to measure enzyme activity.
[0192] The ENZ / CHEK Gelatinase / Collagenase Assay Kit (#E12055) from Invitrogen is designed as an in vitro assay for measuring MMP1 enzyme activity. Any of the active ingredients, combinations of ingredients disclosed in this specification, or compositions containing said combinations can be tested. The analysis relies on the ability of the pure MMP1 enzyme to degrade a fluorescent gelatin substrate. Once the substrate is specifically cleaved by MMP1, bright green fluorescence is displayed and can be observed using a fluorescent microplate reader. The test material is cultured in the presence or absence of pure enzyme and substrate to determine its protease inhibition ability.
[0193] Cyclooxygenase (COX) assay: In vitro cyclooxygenase-1 and cyclooxygenase-2 (COX-1, COX-2) inhibition assay. COX is a bifunctional enzyme with both cyclooxygenase and peroxidase activity. The cyclooxygenase activity converts arachidonic acid to hydroperoxide endoperoxides (prostaglandin G2; PGG2), and the peroxidase component reduces the endoperoxides (prostaglandin H2; PGH2) to the corresponding alcohols, prostaglandins, and coagulation The COX inhibition screening assay measures the peroxidase component of cyclooxygenase. Peroxidase activity is measured by colorimetry by monitoring the appearance of oxidized N,N,N',N'-tetramethyl-p-phenylenediamine (TMPD). The inhibition screening assay includes both COX-1 and COX-2 enzymes to screen isozyme-specific inhibitors. The colorimetric COX (sheep) inhibitor screening test (#760111, CAYMAN CHEMICAL) can be used to analyze the influence of each active ingredient disclosed in the specification, any combination of ingredients, or a composition with the combination on the activity of purified cyclooxygenase (COX-1 or COX-2). According to the manufacturer's instructions, the purified enzyme, heme, and test extract can be mixed in an assay buffer and incubated at room temperature for 15 minutes with shaking. After cultivation, arachidonic acid and a colorimetric substrate can be added to start the reaction. The color change can be evaluated by a colorimetric plate measured at 590nm. The percent inhibition of COX-1 or COX-2 activity can be calculated by comparison with untreated controls to determine the ability of the test extract to inhibit the activity of the purified enzyme.
[0194] Lipoxygenase (LO) assay: In vitro lipoxygenase inhibition assay. LO is a non-heme, iron-containing dioxygenase that catalyzes the addition of molecular oxygen to fatty acids. Linoleate and arachidonate are the main substrates of LO in plants and animals. Arachidonic acid can then be converted to hydroxyeicosatetraenoic (HETE) acid derivatives, which are subsequently converted to leukotrienes, potent inflammatory mediators. This assay provides an accurate and convenient method for screening lipoxygenase inhibitors by measuring the hydroperoxides produced by lipoxygenases (5-LO, 12-LO, or 15-LO) cultured with arachidonic acid. The ability of each of the active ingredients disclosed in this specification, a combination of ingredients, or any of the compositions having the combination to inhibit enzyme activity can be determined using a colorimetric LO inhibitor screening kit (#760700, CAYMAN CHEMICAL). Purified 15-lipoxygenase and the test components can be mixed in assay buffer and incubated with shaking at room temperature for 10 minutes. After incubation, arachidonic acid can be added to initiate the reaction, and the mixture can be incubated for another 10 minutes at room temperature. A colorimetric substrate can be added to terminate catalysis, and the color change can be assessed by a fluorescent plate measured at 490 nm. The percent inhibition of lipoxygenase activity can be assessed compared to an untreated control to determine the ability of each of the active ingredients disclosed in this specification, a combination of ingredients, or any of the compositions having said combinations to inhibit the activity of the purified enzyme.
[0195] Elastase assay: The ENZCHEK® Elastase assay (Kit # E-12056) of Molecular PROBES (Eugene, Oregon USA) can be used as an in vitro enzyme inhibition assay for measuring the inhibition of elastase activity of any of the active ingredients disclosed in this specification, the combination of ingredients, or the composition having the combination. The ENZCHEK kit contains soluble bovine neck ligament elastin, which can be labeled with a dye to quench the fluorescence of the conjugate. Non-fluorescent substrates can be digested by elastase or other proteases to produce highly fluorescent fragments. The resulting fluorescence enhancement can be monitored with a fluorescent microplate reader. The digestion products from the elastin substrate have an absorption maximum at about 505nm and a fluorescence emission maximum at about 515nm. When using the ENZCHEK Elastase Assay Kit to screen for elastase inhibitors, the peptide, N-methoxysuccinyl-Ala-Ala-Pro-Val-chloromethyl ketone, can be used as a selective, common elastase inhibitor.
[0196] Ceramide production: Ceramide in cells or tissue samples can be labeled with mouse monoclonal antibody anti-ceramide (Enzo Life Sciences, reference ALX-804-196 clone MID15B4) diluted to 1 / 50 for 2 hours at room temperature using the amplification system biotin / streptavidin. Video microscopy can be performed to visualize ceramide (pink staining).
[0197] Oil control assay: An analysis for measuring the reduction of sebum secretion in sebaceous glands and / or the reduction of sebum production in sebaceous glands can be analyzed by using standard techniques known to those of ordinary skill in the art. In a specific example, the forehead can be used. Each of the active ingredients disclosed in this specification, the combination of ingredients, or any of the compositions having the combination can be applied once a day or twice a day to a portion of the forehead for a fixed period of days (e.g., 1 day, 2 days, 3 days, 4 days, 5 days, 6 days, 7 days, 8 days, 9 days, 10 days, 11 days, 12 days, 13 days, 14 days or more than 14 days), while the rest of the forehead is not treated with the composition. After a fixed period of days has expired, sebum secretion can be analyzed by applying fine blotting paper to the treated and untreated forehead skin. This is accomplished by first removing all sebum from the treated and untreated areas with wet and dry cloths. The blotting paper is then applied to the treated and untreated forehead areas, and a rubber band can be placed around the forehead to gently press the blotting paper onto the skin. After 2 hours, the blotter can be removed, allowed to dry, and then transilluminated. Darker blotters correspond to more sebum secretion (or lighter blotters correspond to reduced sebum secretion.
[0198] Erythema Assay: An assay to measure the reduction in skin redness can be evaluated using a MINOLTA colorimeter. Skin erythema can be induced by applying a 0.2% sodium lauryl sulfate solution to the subject's forearm. The area is protected with an occlusive patch for 24 hours. After 24 hours, the patch is removed and the irritation-induced redness can be evaluated using the a* value of a MINOLTA colorimeter. The a* value measures the change in skin color in the red area. Immediately following the reading, the area is treated with any of the active ingredients, combinations of active ingredients, or compositions containing said combinations disclosed in this specification. Repeated measurements can be made periodically to determine the ability of the formulation to reduce redness and irritation.
[0199] Determination of skin moisture / hydration: The benefits of skin moisture / hydration can be measured by using impedance measurements performed with a Nova DermalPhase Meter. Impedance meters measure changes in skin moisture content. The outer layer of the skin has different electrical properties. When the skin is dry, it conducts electricity poorly. When it becomes more hydrated, increased conductivity is produced. Therefore, changes in skin impedance (related to conductivity) can be used to evaluate changes in skin hydration. The device can be calibrated for each test day according to the instrument instructions. Temperature and relative humidity can also be marked. The subject can be evaluated as follows: before measurement, it can be balanced in a room with a determined humidity (e.g., 30% to 50%) and temperature (e.g., 68°C to 72°C). Three independent impedance measurements are performed on each side of the face, and they are recorded and averaged. The impedance meter can use the T5 setting, which averages the impedance values applied to the face every five seconds. Changes can be reported with statistical variance and significance. Each of the active ingredients disclosed in this specification, any one of the ingredient combinations, or a composition containing the combination can be tested according to this method.
[0200] Determination of Skin Clarity and Reduction of Freckles and Age Spots: Skin clarity and reduction of freckles and age spots can be evaluated using a Minolta colorimeter. Changes in skin color can be evaluated using the a* value of a Minolta colorimeter to determine potential irritation due to product treatment. The a* value measures changes in skin color in the red area. This is used to determine whether each of the active ingredients disclosed in this specification, any of the combinations of ingredients, or a composition containing the combination reduces irritation. Measurements can be made on each side of the face and averaged as values for the left and right sides of the face. Skin clarity can also be measured using a Minolta Meter. The measurement is a combination of the a*, b, and L values of the Minolta Meter and is related to the brightness of the skin, and corresponds very well to the smoothness and hydration of the skin. Skin determinations are performed as above. In one non-limiting aspect, skin clarity can be described as L / C, where C is chromaticity and is defined as (a / C). 2 + b 2 ) 1 / 2 .
[0201] Skin dryness, surface wrinkles, skin smoothness, and skin color measurement: Skin dryness, surface wrinkles, skin smoothness, and skin color can be assessed using a clinical scoring technique. For example, a clinical score for skin dryness can be determined using a five-point standard Kligman scale: (0) skin is soft and moist; (1) skin appears normal with no visible dryness; (2) skin feels slightly dry to the touch with no visible flaking; (3) skin feels dry, tough, and has a whitish appearance with some scaling; and (4) skin feels very dry, rough, and has a whitish appearance with scaling. The assessment can be performed independently by two clinicians and averaged.
[0202] Skin color clinical score measurement: Skin color was clinically scored using a 10-point analog numeric scale: (10) Smooth uniform skin, pink-brown color. No dark, red, or scaly patches when examined with a handheld magnifier. The microtexture of the skin feels very uniform; (7) Uniform skin color without magnification. No scaly areas, but macules due to hyperpigmentation or erythema. No macules larger than 1 cm in diameter; (4) Skin macules and uneven texture are easily noticed. Few scales. Skin that feels rough to the touch in some areas; and (1) Uneven skin coloration and texture. Multiple areas of scales and macules, hypopigmented, red, or black spots. Large areas of uneven coloration greater than 1 cm in diameter. The assessments were performed independently by two clinicians and averaged.
[0203] Clinical Score Measurement of Skin Smoothness: The clinical score of skin smoothness can be analyzed using a ten-point analog numerical scale: (10) smooth, the skin is moist and shiny, and there is no resistance when a finger is passed over the surface; (7) somewhat smooth, little resistance; (4) rough, visibly changing, and there is friction when rubbed; and (1) rough, flaky, uneven surface. The assessment was performed independently by two clinicians and the average was taken.
[0204] Skin smoothness and wrinkle reduction measurements using the method disclosed in Packman et al. (1978): Skin smoothness and wrinkle reduction can also be measured visually using the method disclosed in Packman et al. (1978). For example, the depth, shallowness, and total number of surface face lines (SFL) for each subject can be carefully scored and recorded at each visit. A numerical score is obtained by multiplying the number factor by the depth / width / length factor. Scores are obtained for the eye area and mouth area (left and right) and added together as a total wrinkle score.
[0205] Skin firmness measurement using Hargens Ballistometer: Skin firmness can be measured using the Hargens Ballistometer, a device that assesses skin elasticity and firmness by dropping a small object on the skin and recording the first two rebound peaks. Ballistometry is a small, lightweight probe that uses a relatively blunt probe (4 square millimeters - contact area). The probe gently penetrates into the skin, resulting in measurements that rely on the properties of the outer layers of the skin, which include the stratum corneum and outer epidermis and part of the dermis.
[0206] Skin Softness / Flexibility Measurement Using Gas Bearing Electrodynamometer: Skin softness / flexibility can be assessed using the Gas Bearing Electrodynamometer, an instrument that measures the pressure / tension properties of the skin. The viscoelasticity of the skin is related to skin moisturization. Measurements of specific sites in the cheek area can be achieved by attaching the probe to the skin surface with double-sided tape. A force of approximately 3.5 gm is applied parallel to the skin surface, accurately measuring the displacement of the skin. The flexibility of the skin can then be calculated and expressed as DSR (dynamic spring rate in gm / mm).
[0207] Determination of the appearance of lines and wrinkles using replicas: The appearance of lines and wrinkles on the skin can be evaluated using replicas, which are impressions of the skin surface. Materials such as silicone rubber can be used. The replicas can be analyzed by image analysis. Changes in line and wrinkle visibility can be objectively quantified by forming the subject's face using a silicon replica and analyzing the replica image with a computer image analysis system. Replicas can be obtained from the eye area and the neck area and photographed with a digital camera at a low lighting incident angle. The digital image can be analyzed with an image processing program and the area of the replica covered by wrinkles and fine lines can be determined.
[0208] Skin surface profile determination using the profilometer / stylus method: The surface profile of the skin can be measured using the profilometer / stylus method. This involves flashing or dragging a stylus across the surface of a replica. The vertical displacement of the stylus can be recorded in a computer via a distance sensor, and after scanning a certain distance of the replica, an analysis of the skin profile can be generated as a two-dimensional surface. This scan can be repeated any number of times along a fixed axis to produce a simulated 3-D image of the skin. Ten random sections of the replica can be obtained using the stylus technique and combined to produce an average. Values of interest include Ra, which is the arithmetic mean of all roughness (height) values calculated by integrating the profile height relative to the mean profile height. Rt, which is the maximum vertical distance between the highest peak and the lowest valley, and Rz, which is the average peak amplitude minus the average peak height. Values are given as values calibrated in mm. The equipment should be standardized before each use by scanning a metal standard of known value. The Ra value can be calculated by the following formula: R a = normalized roughness; lm = lateral (scan) length; and y = absolute value of profile position relative to the average profile height (x-axis).
[0209] MELANODERM™ Assay: In other non-limiting aspects, the efficacy of each of the active ingredients disclosed in this specification, any combination of ingredients, or compositions having such combinations can be evaluated by using a skin analog such as MELANODERM™. Melanocytes, one type of cell in the skin analog, are specifically contaminated when exposed to L-dihydroxyphenylalanine (L-DOPA), a precursor of melanin. The skin analog, MELANODERM™, can be treated as follows: using various matrices containing each of the active ingredients, any combination of ingredients, or compositions containing the combinations disclosed in the specification or using the matrix alone as a control. Alternatively, an untreated skin analog sample can be used as a control.
[0210] Production of filaggrin: Changes in the production of filaggrin in keratinocytes caused by each of the active ingredients disclosed in this specification, any one of the ingredient combinations, or a composition containing the combination can be measured. Filaggrin is a precursor of the natural moisturizing factor (NMF) in the skin. An increase in NMF increases the moisture content of the skin. Using a bioassay that analyzes the concentration of filaggrin in keratinocyte lysates, the production of filaggrin in treated and untreated keratinocytes can be determined. A non-limiting example of a bioassay that can be used to quantify the production of intermediate filament-related proteins is the PROTEINSIMPLESIMON protein blotting protocol. For each sample, normal human epidermal keratinocytes (NHEKs) were grown in EPI-200-MATTEK EPI Life growth medium (M-EP-500-CA) containing calcium from LifeTechnologies. Before treatment, NHEKs were incubated overnight at 37°C in a growth medium with 5% CO2. The NHEKs are then incubated in growth medium containing 1% of the test compound / extract or no compound / extract (negative control) for 24 hours to 36 hours. The NHEKs can then be washed, collected, and stored on ice or in a cooler place until lysed on ice using lysis buffer and sonication. The protein concentration of the sample can be determined and used for normalization of the samples. The lysate can be stored at -80°C until used for quantitative analysis.
[0211] PROTEINSIMPLE ® The SIMON™ Western Blot Bioassay uses a quantitative Western blot immunoassay technique to quantify filaggrin in test samples using a filaggrin-specific antibody. Cell samples are lysed and normalized for protein concentration. Normalized samples and molecular weight standards can then be loaded and run on a denaturing protein separation gel using capillary electrophoresis. The proteins in the gel are immobilized and immunoprobed using a primary antibody specific for filaggrin. The immobilized proteins can then be immunoprobed with an enzyme-linked detection antibody that is bound to the primary antibody. A chemiluminescent substrate solution can then be added to the immobilized proteins, allowing chemiluminescence development proportional to the amount of filaggrin bound in the fixative. The development of chemiluminescence is stopped at a specific time, and the intensity of the chemiluminescent signal can be measured and compared to positive and negative controls.
[0212] Production of occlusin: Changes in the production of occlusin in keratinocytes caused by each of the active ingredients disclosed in this specification, any one of the ingredient combinations, or a composition containing the combination can be measured. Occlusin is a protein that is essential for the formation of tight junctions and the moisture barrier function of the skin. A non-limiting example of how to determine the production of occlusin in treated and untreated keratinocytes is a bioassay using an analysis of the concentration of occlusin in keratinocyte lysates. Bioassays can be performed using the PROTEINSIMPLE® SIMON™ protein blotting protocol. For samples, adult epidermal keratinocytes (HEKa) from Life Technologies (C-005-5C) can be grown in EPILIFE™ growth medium containing calcium from Life Technologies (M-EP-500-CA) and keratinocyte growth supplement (HKGS) from Life Technologies (S-101-5) at 37°C and 5% CO2 for 24 hours. The HEKa are then incubated for 24 to 48 hours in growth medium containing the test compound / extract, no compound / extract as a negative control, or 1 mM CaCl2 as a positive control. The HEKa are then washed, collected, and stored on ice or colder until lysed on ice using lysis buffer and sonication. The protein concentration of the sample can be determined and used for normalization of the samples. The lysate is stored at -80°C until used in the bioassay.
[0213] The PROTEINSIMPLE® SIMON™ Western Blot Bioassay utilizes a quantitative Western blot immunoassay technique that uses an antibody specific for occludin to quantitatively detect occludin in a test sample. Cell samples are lysed and the protein concentration is normalized. The normalized samples and molecular weight standards are then loaded and run on a denaturing protein separation gel using capillary electrophoresis. The proteins in the gel are then immobilized and immunoprobed using a primary antibody against occludin. The immobilized proteins are immunoprobed using an enzyme-linked detection antibody that is bound to the primary antibody. A chemiluminescent substrate solution is then added to the immobilized proteins, allowing chemiluminescence development proportional to the amount of occludin bound in the fixative. The development of chemiluminescence can be stopped at a specific time, and the intensity of the chemiluminescent signal can be measured and compared to positive and negative controls.
[0214] Corneocyte monolayer permeability: Changes in the permeability of the corneocyte monolayer caused by each of the active ingredients disclosed in this specification, any one of the ingredient combinations, or a composition containing the combination can be measured. Corneocyte monolayer permeability is a measure of skin barrier integrity. As a non-limiting example, the in vitro vascular permeability test of MILLIPORE (ECM642) can be used to determine the corneocyte monolayer permeability in treated and untreated corneocytes. This test analyzes the adsorption, transport and permeability of endothelial cells. In short, adult epidermal corneocytes from Life Technologies (C-005-5C) can be seeded onto a porous collagen-coated membrane in a collection well. The corneocytes are then cultured in EPILIFE™ growth medium containing calcium from LIFE TECHNOLOGIES (M-EP-500-CA) and corneocyte growth supplement (HKGS) from LIFETECHNOLOGIES (S-101-5) at 37°C and 5% CO2 for 24 hours. This culture time allows the cells to form a monolayer and seal the membrane pores. The culture medium is then replaced with fresh culture medium containing (test sample) or without (untreated control) the test compound / extract, and the corneocytes are cultured for another 48 hours at 37°C and 5% CO2. In order to determine the permeability of the corneocyte monolayer after culture with / without the test compound / extract, the culture medium is replaced with fresh culture medium containing high molecular weight fluorescein isothiocyanate (FITC)-dextran, and the corneocytes are cultured for 4 hours at 37°C and 5% CO2. During the 4-hour incubation, FITC can pass through the corneocyte monolayer and the porous membrane and enter the collection well at a rate proportional to the permeability of the monolayer. After incubation for 4 hours, the cell viability and FITC content in the collection well can be determined. For FITC content, the medium in the collection well, when excited at 520nm, measures the fluorescence of the medium at 480nm (Em). The percent permeability and percent change compared to the untreated control can be determined by the following formulas: Permeability = ((average Ex / Em of test samples) / average Ex / Em of untreated controls)*100; Percent change = Permeability of test samples – Permeability of untreated controls.
[0215] Production of hyaluronic acid: Changes in the production of hyaluronic acid in human dermal fibroblasts due to each of the active ingredients disclosed in this specification, any one of the combinations of ingredients, or a composition containing the combination can be measured. HA is a polysaccharide that participates in the stabilization of the matrix structure and provides turgor pressure to tissues and cells.
[0216] As a non-limiting example, the HA production in treated and untreated adult dermal fibroblasts (HDFa) can be determined using the hyaluronic acid DuoSetELISA kit of R&D Systems (DY3614). In this analysis, in order to produce samples, sub-fusion HDFa cells from Cascade Biologics (C-13-5C) were incubated at 37°C and 10% CO2 in starvation medium (0.15% fetal bovine serum and 1% penicillin-streptomycin solution in Dulbecco's modified Eagle medium) for 72 hours before treatment. The cells were then incubated with fresh starvation medium containing test compounds, positive controls (phorbol 12-myristic acid 13-acetate (P1585) from SIGMA-ALDRICH and platelet-derived growth factor (P3201) from SIGMA-ALDRICH) or without additives for 24 hours. The culture medium was then collected and frozen at -80°C until used for ELISA determination.
[0217] In short, the ELISA assay uses a quantitative sandwich enzyme immunoassay technique, whereby a capture antibody specific for HA can be pre-coated onto a microplate. Standards and culture media from treated and untreated cells are pipetted into the microplate wells to allow any HA present to be bound by the fixed antibody. After all unbound material is washed away, an enzyme-linked detection antibody specific for HA is added to the wells. After washing to remove any unbound antibody-enzyme reagent, a substrate solution is added to the wells to allow color development proportional to the amount of HA bound in the initial step. Color development is stopped at a specific time, and the color intensity at 450nm is measured using a microplate reader.
[0218] As another non-limiting example, human skin explants can be cultured in a survival explant culture medium in a humidified atmosphere at 37°C, supplemented with 5% CO2. The treatment of the explants can be carried out by topical application of sample products (n = 3) at day 0, day 2, day 3, day 6, day 8 and day 9. Control explants (n = 3) do not receive any treatment except renewing the survival explant culture medium. At day 3, day 6 and day 8, a survival culture medium of half volume can be renewed. At day 9, three explants under each condition can be taken out and cut in half. Half of the explants are fixed in buffered formalin, and the other half are frozen at -80°C.
[0219] After fixing in common Bouin for 48 hours and in formalin for 24 hours, the sample can be dried and immersed in paraffin using the automatic tissue processor Leica TP 1020. 5 micron sections can be made with a microtome (Minot type LEICA RM2125) and mounted on SUPERFROST™ histology slides. Microscopic observation can be carried out by using the optical microscope of a LEICAORTHOPLAN or LEICA DM LB microscope. The image can be taken with an Olympus DP72 camera and CELL^D software. General morphology can be checked on paraffin sections stained with the tricolor Goldner variant of Masson. The staining of hyaluronic acid can be diluted to 1 / 100 1 hour at room temperature with anti-hyaluronic acid biotinylated protein (HABP) (SEIKAGAKU ref 400763-1A), carried out with amplification system biotin / streptavidin (carrier, VECTASTAIN PK-7200).
[0220] Inhibition of hyaluronidase activity: Changes in the activity of hyaluronidase due to each of the active ingredients disclosed in this specification, any one of the combinations of ingredients, or a composition containing the combination can be measured. Hyaluronidase is an enzyme that degrades hyaluronic acid. HA is a polysaccharide that participates in the stability of matrix structure and provides turgor pressure for tissues and cells. As a non-limiting example, an in vitro protocol modified from SIGMA-ALDRICH protocol # EC 3.2.1.35 can be used to determine hyaluronidase activity. In short, 1-S type hyaluronidase (H3506) from SIGMA-ALDRICH is added to a microplate reaction well containing a test compound or a control. Tannic acid can be used as a positive control inhibitor, the control enzyme can not be added to the test compound, and the well containing the test compound or the positive control but not containing the hyaluronidase can be used as a background negative control. Before adding the substrate (HA), the well was incubated at 37°C for 10 minutes. Substrate was added and the reactants were incubated at 37°C for 45 minutes. A portion of each reaction solution is then transferred to a solution of sodium acetate and acetic acid, pH 3.75 and gently mixed to stop that portion of the reaction (stopped well). After adding a portion of the reaction solution to the stopped well, the stopped well and the reaction well should both contain the same volume of solution. Both the reaction well and the stopped well are incubated at room temperature for 10 minutes. The absorbance of the reaction well and the stopped well is then measured at 600nm. The inhibition can be calculated using the following formula: Inhibitor (or control) activity = (absorbance of inhibitor stop well at 600nm – absorbance of inhibitor reaction well at 600nm); Initial activity = absorbance of control enzyme at 600nm; Percent inhibition = [(initial activity / inhibitor activity)*100]-100.
[0221] Peroxisome proliferator-activated receptor gamma (PPAR-γ) activity: Changes in PPAR-γ activity caused by each active ingredient disclosed in the specification, any combination of ingredients, or a composition having the combination can be measured. PPAR-γ is a key receptor for sebum production. As a non-limiting example, the activity of PPAR-γ can be determined using a bioassay that analyzes the ability of a test compound or composition to inhibit ligand binding. Briefly, a fluorescent small molecule pan-PPAR ligand, FLUORMONE™ Pan-PPAR Green, available from Life Technologies (PV4894), can be used to determine whether a test compound or composition is able to inhibit the binding of the ligand to PPAR-γ. Sample wells include PPAR-γ and a fluorescent ligand and: a test compound or composition (test); a reference inhibitor, rosiglitazone (positive control); or no test compound (negative control). The wells are incubated for a set period of time to allow the ligand an opportunity to bind to PPAR-γ. The fluorescence polarization of each sample well can then be measured and compared to the negative control well to determine the inhibition rate of the test compound or composition.
[0222] Cytokine Array: Human epidermal glial cells were cultured to 70% to 80% confluence. The medium in the plate was aspirated and 0.025% trypsin / EDTA was added. When the cells became rounded, the culture dish was tapped to release the cells. The cells containing trypsin / EDTA were removed from the culture dish and balanced. The cells were centrifuged for 5 minutes. To form a cell pellet. The supernatant was aspirated. The resulting pellet was resuspended in EPILIFE™ medium (Cascade Biologics). The cells were seeded into 6-well plates at approximately 10% to 20% confluence. When the cells become approximately 80% confluent, the medium is aspirated and 1.0 mL of EPILIFE™ is added to duplicate wells along with phorbol 13-myristate 12-acetate (“PMA”), an inflammatory inducer for transplantation, and a test composition dilution (i.e., 1.0% (100 μL of 100× stock) and 0.1% (10 μL of 100× stock) test composition diluted into a final volume of 1 mL of EPILIFE™ growth medium). The medium is gently vortexed to ensure adequate mixing. In addition, 1.0 mL of EPILIFE™ is added to the control wells, with or without the addition of PMA. Following preparation, the plates are then incubated at 37±1°C and 5.0 ± 1% CO2 for approximately 5 hours. After the 5 hour incubation, all medium is collected in conical tubes and frozen at -70°C
[0223] For analysis, 16-grid hybridization boxes were attached to three 16-grid FAST sheets arranged in duplicate with 16-grid anti-cytokine antibodies plus experimental controls (WHATMAN BIOSCIENCES), and the sheets were placed in FAST frames (4 sheets per frame) for processing. The array was blocked for 15 minutes. 70mL S&S protein array blocking buffer (WHATMANSCHLEICHER and SCHEULL) was used at room temperature. The blocking buffer was removed and 70mL of each supernatant sample was added to each array. The array was incubated at room temperature for 3 hours with gentle stirring. The array was washed 3 times with TBS-T. The array was processed with 70mL antibody mixture, which contained a biotinylated antibody corresponding to each array capture antibody. The array was incubated at room temperature for 1 hour with gentle stirring. The array was washed 3 times with TBS-T. The array was incubated at room temperature for 1 hour with gentle stirring with 70mL of a solution containing streptavidin-Cy5 conjugate. The array was washed 3 times with TBS-T, rinsed quickly in deionized water, and dried.
[0224] The slides can be imaged in the PERKIN-ELMER SCANARRAY 4000 confocal fluorescence imaging system. The array images can be saved and analyzed using the imaging research ARRAYVISION software. In short, the spot intensity is determined by subtracting the background signal. The spot replicates from each sample condition can be averaged and then compared with the appropriate control.
[0225] Endothelial Tube Formation: Endothelial tube formation is associated with angiogenesis and the formation of microvascular capillaries. Capillary formation and angiogenesis may contribute to skin redness and rosacea. The ability of endothelial cells to form tubes can be determined using a capillary tubule disruption assay with preformed primary human umbilical vein endothelial cells (HUVEC) in a cell culture system in the presence or absence of test extracts and compounds.
[0226] Briefly, HUVECs are cultured in vitro on an extracellular matrix, which stimulates the attachment and tubular morphogenesis of endothelial cells, forming capillary-like luminal structures. These in vitro formed capillaries are similar to human vascular capillaries in many aspects. The capillary assay is based on this phenomenon and is used to evaluate potential vascular targeting agents.
[0227] HUVEC cultures were grown in a 5% CO2 37°C cell culture incubator. The complete growth medium for HUVEC was endothelial basal medium (EBM) supplemented with 2% fetal bovine serum (FBS), 12 μg / mL bovine brain extract, 1 μg / mL hydrocortisone, and 1 μg / mL GA-1000 (gentamicin-amphotericin). HUVEC cultures between passages 3 and 8 were used for all analytical experiments.
[0228] HUVECs are pre-labeled with the fluorescent agent Calcein AM and seeded in 96-well culture plates coated with extracellular matrix containing their complete growth medium. After approximately four hours of the morphogenesis process, endothelial capillaries should be formed. Then, a 50 μL volume of the designed dose of the test agent is applied as a treatment condition to the formed capillary culture. Untreated controls can be added with the vehicle of the test agent. SUTENT ® is an FDA-approved anti-angiogenic drug, and its concentration can be used as a control for assay performance. After approximately six hours of treatment, the morphology of endothelial tubules in each well is examined by microscopy, imaging, and the capillary disrupting activity under the treatment conditions can be quantified. Each test condition can be performed in duplicate wells, including controls.
