FIELD OF THE PRESENT INVENTION

The present invention relates to compositions containing signal transduction modulator compounds, to methods for treating and preventing inflammation using the compounds, and to a method for preparing the compositions.

BACKGROUND OF THE PRESENT INVENTION

Inflammation often is a bodily response to infection or injury in which cells involved in detoxification and repair are mobilized to the compromised site by inflammatory mediators. The infection or injury can be a result of acute or chronic disease, disorders, conditions or trauma, environmental conditions, or aging. Examples of diseases, disorders, including autoimmune disorders, conditions, including environmental conditions, or trauma, in which inflammation plays, or is thought to play a role, include diseases, disorders, syndromes, conditions and injuries of the cardiovascular, digestive, integumentary, muscular, nervous, reproductive, respiratory and urinary systems, as well as, diseases, disorders, syndromes, conditions and injuries of tissue and cartilage such as atherosclerosis, Irritable Bowel Syndrome (IBS), psoriasis, tendonitis, Alzheimer's disease and vascular dementia, multiple sclerosis, diabetes, endometriosis, asthma and kidney failure.
The body's response to inflammation can include various symptoms, including edema, vasodilation, fever and pain, amongst others. For example, when inflammation is localized to joints, swelling of the joint lining, wearing down of cartilage and stiffening of the joints may occur. Thus, inflammation involving joints can be linked to a wide range of underlying joint conditions, from sprains to conditions collectively referred to as “arthritis,” including rheumatoid arthritis. Such inflammation often is associated with autoimmune disorders.
When inflammation is localized to the lungs, symptoms such as swelling and narrowing of the lining of the airways (i.e., bronchial tubes, bronchi) may occur, resulting in constriction of the airways. The inflammation can stimulate production of mucous (sputum), which can cause further obstruction of the airways. Inflammation of the airways is associated with a number of diseases, disorders and conditions. For example, allergic asthma, a disease linked to inflammation of the airways, is thought to be caused by an exaggerated response of the immune system to harmless allergens (e.g., the house dust mite) resulting in a typical infiltration of the airway walls and injury and desquamation of the airway epithelium by e.g., activated eosinophils and lymphocytes. Other types of asthma are provoked by factors including, but not limited to, vigorous exercise, irritant particles, and psychologic stresses. While asthma often is chronic, the inflammation of the airways and resultant obstruction of air flow to the lungs in asthma often is reversible. In contrast, chronic obstructive pulmonary disease (COPD), also known as chronic obstructive lung disease (COLD), which also results in obstruction of air flow to the lungs, is unlike asthma because the obstruction often is not reversible, i.e., it is permanent, and often progressive. COPD includes primarily chronic bronchitis and emphysema.
The term, “inflammatory bowel disease” (also known as Irritable Bowel Syndrome or IBS) often refers to two chronic diseases that cause inflammation of the intestines: ulcerative colitis and Crohn's disease. In ulcerative colitis (an inflammatory disease of the large intestine, i.e., the colon), the inner lining—or mucosa—of the intestine is inflamed (i.e., the lining of the intestinal wall reddens and swells) and develops ulcers. Ulcerative colitis often is most severe in the rectal area. In contrast, Crohn's disease (an inflammatory disease of the small intestine) usually involves the lower part of the small intestine, called the ileum, but it can affect any part of the digestive tract, from the mouth to the anus. In Crohn's disease, the inflammation extends deep into the lining of the affected organ, which can cause pain and make the intestines empty frequently, resulting in diarrhea.
Inflammation also has been shown to play a role in cardiovascular diseases, disorders and conditions. Inflammation of the heart (myocarditis) may result in symptoms such as shortness of breath or fluid retention. In atherosclerosis, the process in which fatty deposits build up in the lining of arteries that can contribute to heart attack and stroke, it is believed that the inner layer of arteries become injured by high blood pressure, tobacco smoke, diabetes, or high levels of triglycerides and cholesterol, thereby triggering an inflammatory response. The inflamed artery lining traps fats, cholesterol, blood platelets, calcium and cellular waste, resulting in the production of plaque. An accumulation of plaque can restrict blood flow through the artery, and rupturing plaque can cause blood clots that block blood flow through the artery. Such blood clots also can break loose, travel to the heart and cause a heart attack, or travel to the brain and cause a stroke. C-reactive protein (CRP) is one of the acute phase proteins that increase during inflammation. It has been suggested that testing the CRP level in blood of an individual may be used to assess cardiovascular disease risk.
In the urinary system, inflammation of the kidneys (nephritis) has been associated with high blood pressure and kidney failure. Nephritis has been linked to various diseases, disorders and conditions such as kidney disease, kidney stones, kidney cancer, gout, Sjogren's Syndrome (an autoimmune disease damaging the eye tear ducts and other glands), lupus, yellow fever and typhoid fever.
Inflammation also has been implicated in various cancers. A genetic link between cancer and inflammation has been discovered by Greten F. R. et al. (Cell, 2004 Aug. 6; 118(3): 285-96), who discovered that the proinflammatory gene I-kappa-B kinase (IKK beta) acts differently in two cell types to initiate cancer, and that deletion of that gene in mice decreased both the incidence of cancer and tumor growth. Strong support for a link between inflammation and cancer, including prostate cancer, breast cancer, ovarian cancer, cervical cancer, colon cancer and pancreatic cancer, can be found in, e.g., Bower, V., J. Natl. Cancer Instit. Feb. 16, 2005; 97(4): 251-253; Caruso, C. et al., Ann. N.Y. Acad. Sci. December 2004; 1028: 1-13; Macarther, M. et al., Am. J. Physiol. Gastrointest. Liver Phiysiol.

Inflammation often is characterized by a strong infiltration of polymorphonuclear leukocytes at the site of inflammation, particularly neutrophils. These cells promote tissue damage by releasing toxic substances at the vascular wall or in uninjured tissue. Neutrophil infiltration results from amplifying cascades of cell-cell communication involving signal transduction proteins, such as G-proteins, that can facilitate intracellular regulation and intercellular communication by interacting with a wide range of different regulatory receptor-transducer proteins, such as membrane bound receptors. For these interactions to occur many of the signal transduction proteins, including virtually all G-proteins, first must be modified by the post-translational addition of a C₁₅farnesyl or a C₂₀geranylgeranyl polyisoprenoid moiety in thioether linkage to a cysteine residue located at or near the carboxyl terminus within a so-called CAAX box or related cysteine-containing sequence. Carboxy-terminal polyisoprenoid cysteines that ultimately result from these modifications can be subject to methylesterification by a specific membrane associated S-adenosylmethionine-dependent polyisoprenyl-S-cysteinyl methyltransferase. Compounds that can inhibit these enzymatic reactions or otherwise alter the interactions among polyisoprenylated signal transduction proteins, such as G-proteins and the protein regulatory targets with which they interact, or other intracellular signaling proteins, can be used to mitigate leukocyte responses and, theoretically, to treat inflammatory-related conditions. (See e.g., Volker, et al., Methods Enzymol., 1995, 250: 216-225).
One signal transduction modulator compound is N-acetyl farnesyl-cysteine (“AFC”), also referred to as N-acetyl-5-trans, trans-farnesyl-L-cysteine. AFC has been shown to inhibit membrane-associated polyisoprenoid methyl transferase and to block some neutrophil, macrophage, and platelet responses in vitro. Laboratory results also indicate that AFC effectively reduces dermal inflammation in mice. AFC requires high concentrations for efficacy and is expected to result in generalized systemic effects and multiple side effects since it interferes with a central cell regulation mechanism, characteristics which would seem to preclude its use in vivo. However, because such inhibitory compounds have the potential to be highly efficacious, there is a need in the art for compositions containing such compounds that can act as a safe and effective antidote for various conditions related to inflammation.
Numerous materials have been used to treat chronic or uncontrolled inflammation, all of which suffer from side effects, some of which are serious, if not life-threatening. For example, products used for relief of inflammation include, without limitation, corticosteroids and NSAIDs (Non-Steroid Anti-Inflammatory Drugs). Corticosteroids, a class of steroids, are used clinically to suppress or control inflammation. The sub-class of corticosteroids known as glucocorticoids are anti-inflammatory by, amongst other mechanisms, preventing phospholipid release and decreasing eosinophil action. Representative examples of corticosteroids useful in reducing inflammation include, without limitation, betamethasone, budesonide, cortisone, dexamethasone, hydrocortisone, methylprednisolone, prednisolone, predinsone, triamcinolone, corticosteroid preparations containing salicylic acid derivatives, and other corticosteroidal topical products for joint and muscular pain that also include tolazoline and dimethyl sulfoxide (“DMSO”). Common side effects of corticosteroids include increased appetite and weight gain, deposits of fat in chest, face, upper back and stomach, water and salt retention leading to swelling and edema, high blood pressure, diabetes, excess sweating, telangiectasia (dilation of capillaries), slowed healing of wounds, osteoporosis, cataracts, acne, hirsutism, muscle weakness, atrophy of the skin and mucous membranes, an increased susceptibility to infection, and stomach ulcers.
As the name suggests, NSAIDs are not steroids, though these compounds have a similar eicosanoid-depressing action to steroids in achieving their anti-inflammatory effect. Representative examples of NSAIDs include, without limitation, aspirin, mofebutazone, clofezone, oxyphenbutazone, benzydamine, etofenamate, piroxicam, felbinac, bufexamac, ketoprofen, bendazac, naproxen, ibuprofen, fentiazac, diclofenac, feprazone, niflumic acid, meclofenamic acid, flurbiprofen, tolmetin, suxibuzone, indometacin, and nifenazone. Aspirin or salicyclic acid was the first discovered member of the NSAIDs class. NSAIDs are not all salicylates, but they have similar effects and mechanisms of action. NSAIDS generally block the activity of the cyclooxygenase (COX) genes, with some blocking both the COX-1 and COX-2 genes, while others more selectively block only one of the two genes. For example, aspirin blocks both COX genes, while the newer celecoxib (Celebrex®, Pfizer, Inc., New York, N.Y.), rofecoxib (Vioxx®, Ceoxx® and Ceeoxx®, Merck & Co., Whitehouse Station, N.J.), and valdecoxib (Bextra®, Pfizer) act specifically on the COX-2 gene, and consequently, are often referred to as COX-2 selective inhibitors or coxibs (CycloOXygenase-2 inhiBitors). Other coxibs include, e.g., Etoricoxib (Arcoxia®, Pfizer) and lumiracoxib (Prexige®, Novartis, Basel, Switzerland).
The specificity of coxibs allows these NSAIDs to reduce inflammation with minimal gastrointestinal side effects, such as dyspepsia, ulcer perforation, and upper gastrointestinal bleeding that are common with NSAIDs that act on both COX genes. Studies, however, have demonstrated an increased risk of cardiovascular events associated with the use of the coxibs celecoxib, valdecoxib and parecoxib than with other NSAIDs. (See, e.g., Solomon et al., N Engl J Med 2005; 352: 1071-80; Nussmeier et al., N Engl J Med 2005; 352:1081-91). Side-effects of NSAIDS vary between drugs, but generally include nausea, vomiting, diarrhea, constipation, decreased appetite, rash, dizziness, headache, drowsiness and photosensitivity. NSAIDs also may cause fluid retention, leading to edema. The most serious side effects of NSAIDs use are kidney failure, liver failure, ulcers and prolonged bleeding after an injury or surgery. NSAIDs can produce shortness of breath in individuals allergic to them. People with asthma are at a higher risk for experiencing serious allergic reaction to NSAIDs. Individuals with a serious allergy to one NSAID are likely to experience a similar reaction to a different NSAID.
Thus, there is a need for a non-steroidal anti-inflammatory compound that lacks the side effects of corticosteroids and NSAIDS. It now has been found that signal transduction modulator compounds can impede inflammation. Without being bound by any particular theory, the impediment of inflammation likely is a result of the ability of signal transduction modulator compounds to tone down cell to cell signaling. The present invention, therefore, is directed to compositions and uses of signal transduction modulator compounds for treating and preventing inflammation, and for other unmet needs.

DETAILED DESCRIPTION OF THE PRESENT INVENTION

In one aspect, the present invention provides compositions having a signal transduction modulator compound, for example and without limitation, N-acetyl farnesyl-cysteine (AFC), for treating, or preventing, inflammation, or for promoting overall health of the various anatomical systems and their related joints, tissues, and organs. The compositions of the present invention can be employed usefully in pharmaceutical compositions.
In some embodiments, the composition of the present invention is used to treat inflammation. As used herein, “treating,” “treat” or “treatment” includes abrogating, substantially inhibiting, slowing or reversing the progression of a condition, substantially ameliorating clinical or aesthetical symptoms of a condition, protecting from harmful or annoying stimuli, or generally promoting health.
In some embodiments, the composition of the present invention is used to prevent inflammation. “Preventing,” “prevent” or “prevention,” as used herein, includes keeping from happening, anticipating or countering in advance a condition or symptoms of a condition, including the appearance of clinical or aesthetical symptoms of a condition, protecting from harmful or annoying stimuli, or generally promoting health.
In some embodiments, the composition of the present invention is used to promote healthy joints. As used herein, “promoting,” “promote” or “promotion” includes contributing to, furthering, helping or maintaining the progression and/or growth of a joint.
As used herein the term “inflammation” refers to a physiologic response to infection and injury in which cells involved in detoxification and repair are mobilized to the compromised site by inflammatory mediators. The classic signs of inflammation are pain (dolor), heat (calor), redness (rubor), swelling (tumor), and loss of function (functio laesa). Histologically, inflammation involves a complex series of events, including dilatation of arterioles, capillaries and venules, with increased permeability and blood flow; exudation of fluids, including plasma proteins; and leukocytic migration into the inflammatory focus.
The term “acute inflammation,” as used herein, refers to inflammation, usually of sudden onset, characterization by the classical signs, with predominance of the vascular and exudative processes. The term “chronic inflammation,” as used herein, refers to inflammation of slow progress and marked chiefly by the formation of new connective tissue; it may be a continuation of an acute form or a prolonged low-grade form, and usually causes permanent tissue damage.
Regardless of the initiating agent, the physiological changes accompanying acute inflammation encompass four main features: (1) vasodilation, which results in a net increase in blood flow, is one of the earliest physical responses to acute tissue injury; (2) in response to inflammatory stimuli, endothelial cells lining the venules contract, widening the intracellular junctions to produce gaps, leading to increased vascular permeability, which permits leakage of plasma proteins and blood cells out of blood vessels; (3) a strong infiltration of leukocytes at the site of inflammation, particularly neutrophils, which promote tissue damage by releasing toxic substances at the vascular wall or in uninjured tissue; and (4) fever, produced by pyrogens released from leukocytes in response to specific stimuli.
During the inflammatory process, soluble inflammatory mediators of the inflammatory response work together with cellular components in a systemic fashion in the attempt to contain and eliminate the agents causing physical distress. The term “inflammatory mediators,” as used herein, refers to the molecular mediators of the inflammatory process. These soluble, diffusible molecules act both locally at the site of tissue damage and infection and at more distant sites. Some inflammatory mediators are activated by the inflammatory process, while others are synthesized and/or released from cellular sources in response to acute inflammation or by other soluble inflammatory mediators.

As used herein, “joint” is meant to include the more or less movable junction in the body where two or more bones meet and the different kinds of ligaments, tendons, cartilages, bursae, synovial membranes and bones comprising the mobile skeletal-system of a mammal in various quantities and configurations. The composition of the present invention is useful with joints including, but not limited to, ankles, hips, shoulders, knees, wrists, fingers, toes and the like.
As used herein, the terms “signal transduction modulator compound,” “signal transduction modulator” and “STM” refer to a compound that can inhibit, alter or reduce the activity of a G-protein and of the protein regulatory targets of the G-protein. As used herein a “G-protein” refers to a heterotrimeric polyisoprenylated protein that associates with receptors of the seven transmembrane domain super family (i.e., G protein-coupled receptors (GPCRs)), and is involved in signal transduction, and to a small GTP-binding signal transduction protein that acts to regulate cellular processes, including, but not limited to, cytoskeletal organization and secretion, and to any other protein that is subject to polyisoprenylation such as, but not limited to, arrestin and nuclear laminar proteins.
Without being limited by theory, compounds known in the art to inhibit, alter or reduce G-protein signal transducing activity act by, inter alia, affecting the ability of a G-protein to bind to an interacting regulatory target protein that is frequently, although not always, located in the cell membrane. In order to interact with these regulatory target proteins, G-proteins and other polyisoprenylated proteins undergo several post-translational modifications including covalent attachment of a farnesyl or geranylgeranyl moiety in thioether linkage to cysteine residues located at or in close proximity to their carboxy terminal farnesyl- or geranylgeranyl-S-cysteine residues.
Inflammatory agonists stimulate the methyl esterification of polyisoprenyl-S-cysteinyl residues of some G-proteins (Volker, et al., Methods Enzymol., 1995, 250: 216-225). Agents that inhibit the methyl esterification reaction inhibit G-protein-mediation inflammatory responses. Consequently, without being bound by theory, such polyisoprenyl-5-cysteine carboxyl methyltransferase inhibitors may serve as anti-inflammatory agents (Volker, et al., Methods Enzymol., 1995, 250: 216-225).
Other mechanisms for G-protein inhibition are discussed in Volker, et al. (1991), “effects of farnseylcysteine analogs on protein carboxyl methylation and signal transduction” J. Biol. Chem. 266: 21515-22, herein incorporated by reference.

Another suitable unit-dose container which provides a superior moisture barrier is formed from an aluminum foil plastic laminate. The pharmaceutical-based powder is filled by weight or by volume into the depression in the formable foil and hermetically sealed with a covering foil-plastic laminate. Such a container for use with a powder inhalation device is described in U.S. Pat. No. 4,778,054 and is used with GlaxoSmithKline's diskhaler, e.g., Ventolin Disks® (U.S. Pat. Nos. 4,627,432; 4,811,731; and 5,035,237).
As used herein, “cutaneous” or “cutaneously” refers to application to the skin for a local (topical) effect or bodywide (systemic) effect such as that achieved percutaneously (transdermally). Cutaneous administration involves “topical administration” or “topically applying,” which describes the direct application onto one or more surfaces including epithelial surfaces covering an affected area, e.g., a joint. Such a composition can be applied by, e.g., pouring, dropping, spraying, or wiping or rubbing on if a liquid; rubbing or wiping on, if an ointment, lotion, cream, paste, gel, or the like; dusting, if a powder; spraying, if an aerosol composition; or by any other appropriate means. When the composition is sprayed it can be from a compressed air source or pump. Cutaneous administration also can involve the use of transdermal administration such as transdermal patches or iontophoresis devices, which are prepared according to techniques and procedures well known in the art. The terms “transdermal delivery system”, transdermal patch” or “patch” refer to an adhesive system placed on the skin to deliver a time-released dose of a drug(s) by passage from the dosage form through the skin to be available for distribution via the systemic circulation. Transdermal patches are a well-accepted technology used to deliver a wide variety of pharmaceuticals, including, but not limited to, scopolaminee for motion sickness, nitroglycerin for treatment of angina pectoris, clonidine for hypertension, estradiol for post-menopausal indications, and nicotine for smoking cessation.

In the broadest pharmacological sense a “protective agent” or “protectives,” as used herein, refers to any agent that isolates the exposed surface of skin or membrane (e.g., mucous membrane) from harmful or annoying stimuli. A protective can take the form of dusting powders, adsorbents, mechanical protective agents, and plasters. Dusting powders are relatively inert and insoluble materials that are used to cover and protect, e.g., epithelial surfaces, ulcers, and wounds. Usually these substances are finely subdivided powders that absorb moisture and can act as a desiccant. The absorption of skin moisture decreases friction and also discourages certain bacterial growth. Some of the materials that are used as protective adsorbents include bentonite, insoluble salts of bismuth, boric acid, calcium carbonate (precipitated), cellulose, corn starch, magnesium stearate, talc, titanium dioxide, zinc oxide, and zinc stearate.
A protective also can be administered to the skin to form an adherent, continuous film that can be flexible or semi-rigid depending on the materials and the formulations as well as the manner in which they apply. This protective material can serve several purposes including providing occlusion from the external environment, providing chemical support, and serving as vehicles for other medicaments. Mechanical protectives generally are either collodions or plasters. Examples include, without limitation, aluminum hydroxide gel, collodions, dimethicone, petrolatum gauze, adsorbable gelatin film, adsorbable gelatin sponge, zinc gelatin, kaolin, lanolin, anhydrous lanolin, mineral oil, mineral oil emulsion, mineral oil light, olive oil, peanut oil, petrolatum, silicones, and the like.

In a solution, the molecules of the solute or dissolved substance are uniformly distributed among those of the solvent. Solvents that can be useful in the compositions of the present invention include water, as well as organic solvents such as the alcohols (e.g. ethanol or isopropanol, acetone).
In some embodiments, the composition of the present invention is an emulsion. As used herein, “emulsion” refers to a colloid system in which both the dispersed phase and the dispersion medium are immiscible liquids where the dispersed liquid is distributed in small globules throughout the body of the dispersion medium liquid. The globule size is critical and must be such that the system achieves maximum stability. Usually, separation of the two phases will occur unless a third substance, an emulsifying agent, is incorporated. Thus, a stable basic emulsion contains at least the two liquids and the emulsifying agent, and often additionally, an active agent. Common types of emulsions are oil-in-water, where oil is the dispersed liquid and an aqueous solution, such as water, is the dispersion medium, and water-in-oil, where conversely, an aqueous solution is the dispersed phase. It is possible also to prepare emulsions that are basically non-aqueous, for example, using anionic and cationic surfactants of the non-aqueous immiscible system of glycerol and olive oil. An emulsion of a composition of the present invention can have a number of other materials that are immiscible along with the compound of the present invention (e.g., AFC). When the composition of this invention is an emulsion including AFC, non-lipid based vehicles are preferred due to the lipophilic nature of the compound. Emulsifying agent carriers useful in the present invention are described hereinabove.
In some embodiments, the compositions of the present invention can be mixed with a gel suspension (a semisolid carrier) or solid carrier to form a paste, powder, ointment, cream, lotion, hydrogel, and the like.

EXAMPLES OF MODELS

The following are examples of models in which to test the efficacy of signal transduction modulator compounds as a new class of inflammation acting compounds that can mimic the effectiveness of corticosteroids in inflammation processes without the undesirable side effects of corticosteroids. Such examples are not intended to limit the scope of what the inventors regard as their invention nor have the inventors intended to represent that the in models below are the only ones that should or could be used to test the efficacy of the present invention.

Topical Inflammation Models

Example 1

Signal Transduction Modulator Compound AFC in an Acetone Carrier Suppresses TPA-Elicited Edema in the Murine Ear Acute Contact Irritation Model

In order to assess the effects of a representative composition of the present invention, a composition of AFC for reducing edema in the mouse ear model, an established model of dermal inflammation, was used. (See Carlson, R. P., et al., Modulation of mouse ear edema by cyclooxygenase and lipoxygenase inhibitors and other pharmacologic agents. Agents Actions, 1985. 17(2): 197-204; Kuehl, F. A., Jr., et al., Role of prostaglandin endoperoxide PGG2 in inflammatory processes. Nature, 1977. 265(5590): 170-3; Trancik R J, L. N., Evaluation of topical nonsteroidal anti-inflammatory agents, in Models in Dermatology, L. Maibach, Editor. 1985, Karger. pp, 35-42; and Tramposch, K. M., Skin Inflammation, in In Vivo Models of Inflammation, M. L. Morgan D W, Editor. 1999, Birkhauser Verlag. pp. 179-204.)
The standard agents for initiating inflammation were the phorbol ester, tetradecanoylphorbol acetate, (TPA) and arachidonic acid (AA). TPA produces a greater and more prolonged neutrophil infiltration response than AA (See Rao, T. S., et al., Comparative evaluation of arachidonic acid (AA)-and tetradecanoylphorbol acetate (TPA)-induced dermal inflammation. Inflammation, 1993.17(6): 72341.) TPA-induced inflammation is the preferred agent and was used for this example.
A. Dose Response Curve for Irritant.
A dose response range for TPA, a compound known to induce edema, was determined. TPA produces an increase in edema (ear swelling) that reaches a maximum at 6 hours.
Increasing concentrations of TPA dissolved in acetone were applied with the aid of a micropipetter onto the right ear of each of the five 6-8 week old, male Swiss Webster mice used in this analysis. Ten microliters (10 μl) were spread evenly onto the inner and outer surfaces using the pipette tip. The mice then were returned to their cages. The contralateral ear was treated only with acetone. After 5.5 hours, the mice were sacrificed and 6 mm punches were taken from each ear and weighed. Edema response was expressed as a percent increase in the treated ear's weight over the untreated ear. The dose response curve, as well as an ED₅₀value, was determined using the Lichtfield method (Lichtfield J T W. F., A simplified method of evaluating dose-effect experiments, Journal of Pharmacology and Experimental Therapeutics, 1948, 96: 99-113).
As seen in FIG. 1, the increase in ear weight depends on TPA dose from 0.25 to 1.75 μg/20 μl, reaching a maximum increase of approximately 150% of the acetone-treated ear. This experiment identified doses between 1.5-2.0 μg/20 μl as suitable to use in eliciting edema in future tests of anti-inflammatory agents.
B. Signal Transduction Modulator Compound AFC in an Acetone Carrier, Itself, is not an Irritant.
A range of from about 5 mg to about 32 mg AFC, a polyisoprenyl-protein inhibitor compound, was mixed with 20 μl acetone to produce an inventive AFC composition. Each concentration was applied with the aid of a micropipetter onto the right ear of each of six mice so that 10 μl of each of the concentrations of the AFC inventive compositions were applied to an inner ear surface and 10 μl was applied to an outer ear surface of the right ear. The AFC inventive compositions were spread evenly with a pipette tip. Each contralateral ear was treated with only acetone in the same manner. The mice then were returned to their cages. After 5.5 hours, mice were sacrificed and 6 mm punches were taken from each ear and weighed. Edema response was expressed as the percent increase in the treated ear's weight over the untreated (acetone, vehicle only) ear.
As shown in FIG. 2, AFC in acetone alone had no effect on the edema response. The AFC inventive compositions had no effect on the ear punch biopsy weight at a dose up to about 32 mg/20 μl. AFC did not induce edema on its own at doses 60-fold greater than doses having efficacy against chemically-induced edema. This finding suggests an excellent safety profile for AFC.
C. Result of AFC Inventive Composition on TPA-Induced Edema.
In order to assess the effects of the inventive composition on TPA-induced edema, 2 μg of TPA in 20 μl acetone was applied with the aid of a micropipetter onto both ears of each of 6 mice. The mice were returned to their cages. Fifteen minutes later, increasing concentrations of AFC in 10 μl of acetone were applied to the inside and outside surfaces of the right ears as described above. Twenty microliters (20 μl) of an acetone vehicle was applied similarly to the left ear of each mouse as an internal negative control. After treatment, the mice were returned to their cages for 5.5 hours. The mice were sacrificed by cervical dislocation. The ears were immediately removed at their base and a 6 mm diameter punch biopsy was taken from the center of each ear. The ear punch was weighed on an analytical balance for edema measurements as described above. The ability of the various concentrations of AFC to inhibit TPA-induced edema was assessed by determining the difference in weight between the AFC-treated ear and the acetone (vehicle)-only treated ear over the increase in ear punch weight induced by TPA.
When AFC was tested in this acute inflammation mouse-ear assay, AFC reduced acute chemically induced inflammation significantly. The inventive composition reduced the TPA-induced ear weight increase in a dose dependent manner (FIG. 3). The inventive composition resulted in a maximum 80% reduction in edema. The ED₅₀of the inventive AFC composition was approximately 0.44 mg/20 μl for TPA-induced edema inhibition.

Example 2

AFC Inhibits TPA-Induced Neutrophil Infiltration in Mice

A. TPA induces neutrophil infiltration in mice.
Acute contact irritants such as TPA can also induce dermal infiltration of neutrophils. This may or may not be independent of the reduction of edema, as: 1) the maximum neutrophil response is delayed relative the maximal edema response; 2) some irritants will induce edema independent of neutrophil infiltration; and 3) some of the known anti-inflammatory agents reduce one, but not the other. (See Rao, T. S., et al., Comparative evaluation of arachidonic acid (AA)-and tetradecanoylphorbol acetate (TPA)-induced dermal inflammation. Inflammation, 1993, 17(6): 723-41.) In this experiment, the aim was to determine if topically applied AFC would affect neutrophil infiltration in response to acute topical irritation produced by TPA.
Neutrophil-infiltration Assay: Swiss Webster male mice (n=6) were treated with 1 μg/20 μl of TPA as described above in order to assess whether or not TPA induced neutrophil infiltration Acetone was used as a control. TPA was administered as described above. The mice were returned to their cages for 24 hrs to allow neutrophil infiltration, then sacrificed by cervical dislocation. The ears were removed immediately for punch biopsy, and punches were fixed for subsequent histological analysis and MPO enzymatic assay.
MPO Assay: This assay measures myeloperoxidase, (“MPO”) which is packaged in the primary granules of mature granulocytes including the neutrophil. Thus, the amount of MPO in the ear is proportional to the number of infiltrating neutrophils.
MPO enzyme activity of the ears was assayed using the technique detailed by Griffiths and coworkers (1988). To conduct the assay, each ear was homogenized in 1.0 ml of cetyltrimethylammonium bromide buffer for 5 sec using a Pro 200 tissue blender (Pro Scientific, Inc., Oxford, Conn.) at setting 5. These samples then were centrifuged for 5 minutes at 15,000 rpm in a 5415 Eppendorf microcentrifuge. Triplicate 20 microliter aliquots of supernatant were added to 200 microliters of reaction mixture (1.25 ml IM Potassium Phosphate, 4.175 mg o-dianisidine dihydrochloride and 5 μl of 1% peroxide in a final volume of 25 ml). Absorbance at 450 nm then was measured at room temperature at three 60 second intervals using Bio-Kinetics Reader EL 312E (Bio-Tek Instruments). Activity of the homogenate, which was determined by a Bradford assay (BioRad Protein Assay, BioRad Laboratories, Inc. Hercules, Calif.), was expressed as units MPO per mg tissue +/−standard error.
Neutrophil Counting Assay: Ear punches buffered in 10% formalin in PBS at ambient temperature for a minimum of 24 hrs. were sectioned and stained with Hematoxilin & Eosin (“H&E”). The number of neutrophils, identified by their multilobular nuclei, in 6 randomly 100× magnified fields distributed along the length of the ear were counted manually The results are expressed as the average number per field for each ear.
B. AFC inhibits TPA-induced neutrophil infiltration.
Inventive AFC compositions also were used to assess efficacy in the reduction of dermal neutrophil infiltration. (See Rao, T. S., et al., Comparative evaluation of arachidonic acid (AA)-and tetradecanoylphorbol acetate (TPA)-induced dermal inflammation. Inflammation, 1993. 17(6): 723-4 for a discussion regarding the relationship between edema and neutrophil infiltration and the effect of known anti-inflammatory agents on these variables.)
Two micrograms (2 μg) of TPA in 20 μl of acetone was applied onto both ears of each mouse to induce neutrophil infiltration. After 15 minutes, varying concentrations of AFC in acetone were applied to the right ear of each mouse. After 24 hours, the mice were sacrificed. The ears were removed and the efficacy of AFC on neutrophil infiltration was assessed by an MPO assay and histological analysis.
1. MPO Analysis
The results showed that AFC acts to reduce neutrophil infiltration in a dose dependent manner when neutrophil infiltration is measured by an MPO analysis. When AFC was tested in the Neutrophil-Infiltration Assay, it was found to have no inflammation activity of its own. The data indicate that AFC produced over an 80% inhibition of TPA-induced increases in MPO activity and had an ED₅₀of 0.065 mg/20 μl (FIG. 4).
2. Neutrophil Counts:
This histological analysis demonstrated the efficacy of AFC in suppressing dermal neutrophil infiltration in response to acute contact irritation. As seen in FIG. 5, the presence of neutrophils in the TPA alone treated ears was observed clearly at 24 hours after treatment. Essentially no neutrophils were observed in the ears that were not exposed to TPA. In the ears pretreated with TPA and then treated with vehicle or AFC, the numbers of neutrophils were comparable between vehicle plus TPA-treated ear and ears treated with TPA alone. A substantial reduction of neutrophils can be observed in the AFC treated ear.
Upon counting the neutrophils (FIG. 6), 1.0 mg/20 μl₉of AFC produced a statistically significant 80% reduction in dermal neutrophils produced in response to acute contact irritation by TPA. (Statistical significance was calculated using a Student's paired t-test).
C. The Effect of AFC on Neutrophils is Time Dependent
The effectiveness of AFC treatment at various times before and after TPA application was assessed using MPO as a measure of neutrophil infiltration. In this example, both ears of six mice were treated with a 1 μg/20114 dose of TPA in acetone. The right ear then was treated with 1 mg/20 μl AFC inventive composition at various times before and after TA application, while simultaneously treating the contralateral ear with acetone.
The results show the efficacy of AFC treatment prior to, simultaneous with, or after exposure of skin to TPA (FIG. 7). There was a gradual decrease in MPO activity with time at which AFC was applied after TPA application, the steroid dexamethasone showed a similar time dependence. Thus, it can be anticipated that AFC will act like steroids in reducing established inflammatory conditions.
These results support a wide range of possible cosmetic and pharmaceutical applications for AFC.

Example 3

The AFC Inventive Composition does not Exhibit Systemic Effects

The effect of AFC on TPA induction of neutrophil MPO activity was compared with two other agents representing different classes of commonly used anti-inflammatories that inhibit inflammation by mechanisms different from AFC. These included dexamethasone, a steroid, and indomethasone, a non-steroid anti-inflammatory drug, which targets cycloxygenases. The action of AFC in this model was, therefore, compared to that of dexamethasone and indomethasone. Each of these agents were tested using the same protocols used to test AFC.
As shown in FIGS. 8B and 8C, when the concentration of dexamethasone and indomethasone is increased, the contralateral vehicle-treated ear shows increasing inhibition of MPO activity, reflective of inhibition of neutrophil infiltration. This is evidence that topically applied dexamethasome and indomethasone are entering the circulation and exerting a systemic effect with increasing effective local doses. With AFC, no effect was seen on the vehicle-treated ear (FIG. 8A). Topically applied AFC, even at its highest effective local doses is not entering the circulation and, therefore, has no systemic effect in the mouse model.

Example 4

Effect of an AFC and Acetone Composition on Arachadonic Acid-Induced Edema and Arachadonic Acid-Induced Neutrophil Infiltration

Arachadonic acid (“AA”), another standard agent that is used routinely as a contact irritant in the mouse ear model to assay the effectiveness of both steroidal and nonsteroidal anti-inflammatory agents, is the metabolic precursor for a number of lipoxygenase and cyclooxygenase products. Its mechanism of action and, thus, the signaling pathways it activates, differ from those activated by topically applied TPA. AA produces a more rapid edema than TPA that peaks at 1 hour after application. There is minimal histologically observable neutrophil infiltration in response to AA, but an increase in MPO can be detected. Experience has shown that effectiveness against cyclooxygenase activated inflammation in this model is less predictive of effectiveness against human inflammatory diseases than effectiveness against TPA activated inflammation.
The effect of the inventive compositions on arachidonic acid (AA) induced inflammation was assayed using the same protocols as above, but with the following modifications. AA was applied to both ears at 4 mg/40 μl acetone. The ears were harvested at 1 hour to measure edema, the maximum response time, and at 5 hours for inflammatory neutrophil infiltration as measured by an MPO assay.
The AFC inventive composition, prepared as described above, was less effective in reducing granulocyte infiltration induced by AA than TPA. It has 50% of the activity of TPA and a 10 fold higher ED₅₀(FIG. 9).

Example 5

AFC Inventive Composition Visibly Reduces TPA-Induced Erythema

For this example, both ears of a mouse were treated with a 1 μg/20 μl dose of TPA in acetone. After 1 hour, the right ear was treated with 1 mg/20 μl of inventive AFC composition and the left ear was treated with acetone alone. The photo was taken 23 hours later using a Nikon D70 digital camera. An effect of the AFC inventive composition on TPA-induced erythema was observed (FIG. 10).

Example 6

AFC Inventive Compositions Reduce Inflammation in Humans when Pre-Applied

An irritant was applied to the middle of the upper back of a human subject using a 0.2 ml 20% SDS solution and a Hill-Top Chamber patch with Webril pad. AFC, at a concentration of 140 mM in aqueous formulation, was pre-applied to patch areas 1 a and 1 b (FIG. 11). Patches 1 a and 2 a were removed after 2 hours, while patches 1 b and 2 b were removed after 2 hours and 30 minutes. High levels of irritation were visible in patch sites 2 a and 2 b. Site 1 a showed normal skin while 1 b showed a mild response. These results show that the inventive composition can reduce or prevent inflammation when human skin is exposed to an irritant.

Example 7

The Effect of AFC on Chronic Irritation in Mice

The effectiveness of the inventive compositions against established chronic irritation can be assayed using a modification of the technique of Stanley P L et al., Mouse skin inflammation induced by multiple topical application 12-O-tetradeconoyphorbol-13-acetate. Skin Pharmacol. 1991, 4(4):262-71. Both ears of each mouse are treated with TPA in acetone, as above, in a series of 5 applications on the mornings of days 0, 2, 4, 7, and 9. The treated ear receives the inventive compositions containing AFC and acetone, in series of three paired applications, such that it is applied 6 hours apart on days 7, 8 and 9. Punches of the ears then are taken the afternoon of the tenth day and prepared, as above, for the edema assay and the infiltration of neutrophils. Total granulocyte infiltration then is assayed by measuring MPO activity. Macrophage infiltration is determined immunocytologically using the MOMA-2 antibody. Hydrocortisone, which is known to reduce inflammatory edema granulation infiltration and microphage infiltration, can be used as a positive control. It is contemplated that the results likely will show that AFC in acetone reduces chronic edema and neutrophil number in mice.

Example 8

The Effect of the AFC Inventive Composition on Delayed-Type Hypersensitivity

The mouse ear model, described above, can be modified to assay the effect of anti-inflammatory agents in an immune based inflammation model (See Tramposch, K. M., Skin Inflammation, in In Vivo Models of Inflammation, M. L. Morgan D W, Editor. 1999, Birkhauser Verlag. pp. 179-20 and Chapman, J. P., Z. Ruben, and G. M. Butchko, Histology of and quantitative assays for oxazolone-induced allergic contact dermatitis in mice. Am J Dermatopathol, 1986. 8(2): 130-8). In this model, a sensitizing dose of dinitrofluorobenzene (DNFB) 1-3% in acetone can be applied topically according to a modification of the method by Back et al. to the shaved bellies of mice to elicit an immune response. (See Back, O. and T. Egelrud, Topical glucocorticoids and suppression of contact sensitivity. A mouse bioassay of anti-inflammatory effects. Br J Dermatol, 1985. 112(5): 539-45 and Bailey, S. C., et al., A novel contact hypersensitivity model for rank-ordering formulated corticosteroids. Inflamm Res, 1995. 44 Suppl 2: S162-3.) Mice then are challenged on day 5 with 40 μl of 0.5-1% DNFB to each ear. The AFC inventive compound is applied either 0.5 hour before or 15 min after the challenge to one ear and the vehicle is applied to the other ear. The ears are assayed for edema or neutrophil infiltration 5 hours later. Dexamethasone is used as a positive control. Five days later, the ears are challenged topically with a dose of DNFB insufficient to produce contact irritation. Simultaneously, cell infiltration studies are initiated. It is predicted that there initially will be more neutrophils than macrophages; but by 48-72 hours, macrophages will be the predominant population. Its contemplated that no inflammatory response will be seen, and the inventive AFC composition is, therefore, effective in reducing both edema and neutrophil infiltration.

Joint Inflammation Models

These models are used to show that the compounds of the present invention can treat or prevent joint inflammation.

Lewis Rat Adjuvant-Induced Arthritis Model

Male Lewis rats are immunized with the adjuvant at the base of the tail on Day 0. On Day 7, 14, or 21 (or shorter or longer, depending on the study's goals) the rats' rear paw volume can be measured macroscopically by blinded observers for edema. The paws can then be amputated and x-raved for bone/joint destruction via a grading system of 0-4 called the “radiological index.” Such a model is employed in Yamashita, A. et al. (2002) The Journal of Immunology 168: 450-457; Zhao, H. et al. (2000) J. Orthop. Sci. 5:397; and Barbier, A., et al. (1986) Ann. Rheum. Dis. 45:67.

The whole joints can be removed, fixed, embedded in paraffin, sectioned, and stained for inflammatory cell infiltration. Bone and joint destruction, a characteristic of collagen-induced arthritis, can be measured as well. The collagen induced arthritis model using DBA-1/BOM mice is described by Lubberts, E. et al. (2000) J. Clin. Invest. 105: 1697; and Lubberts, E. et al. (2003) J. Immunol. 2003: 2655-2662.

Irritable Bowel Disease Model

This model can be used to show that the compounds of the present invention can treat or prevent inflammation caused by irritable bowel disease.

Example 11

Acetic Acid Induced Irritable Bowel Disease in Rats

Male Sprague-Dawley rats have IBS (irritable Bowel Syndrome) induced via intracolonic instillation of 4% acetic acid solution, and are allowed to recover for six days. On day seven, collection and measurement of inflammation is performed. Colonic segments are removed and put under tension to simulate motor activity of intestinal circular muscles. The effect of a drug on the colonic motor activity is quantified by measuring the mean intraluminal pressure at a given concentration. The mean intraluminal pressure is calculated digitally by dividing an integral value of pressure (area under the pressure trace) by the number of data points (tracing time). The acetic acid induced IBS model is described by La, J. H. et al. (2005) World J. Gastroenterol. 11(2): 237-241.

Then the rats undergo an airway challenge using 5% aerosolized OVA or bovine serum albumin (BSA) delivered through orotracheal intubation using a rodent pulmonary mechanics system. The lungs then are processed via 2 mM EDTA/PBS perfusion through the right ventricle; broncho-alveolar lavage (BAL) fluid samples are collected through tracheostomy, the lungs are fixed at 25 cm H₂O by tracheobronchial infusion of 4% paraformaldehyde/PBS or 10% formalin BS; and tissue sections are obtained in parahilar and midsagittal orientation. This rat induced asthma model is described by Ramos-Barbón, D., et al. (2005) J. Clin. Invest. 115: 1580-1589.
