All patents, patent applications and publications cited herein are hereby incorporated by reference in their entireties.

3. BACKGROUND OF THE INVENTION

Inflammatory pathways underlie the key pathophysiology of many chronic and acute diseases. Unresolved inflammation is important in many chronic disorders, including, but not limited to, heart disease, atherosclerosis, type 1 and type 2 diabetes, dyslipidemia, asthma, arthritis (including rheumatoid arthritis (RA)), osteoarthritis, cystic fibrosis, muscle wasting disease (including muscular dystrophy), pain, insulin resistance, oxidative stress, inflammatory bowel disease (IBD) (including colitis and Crohn's disease), and neurodegenerative disease (including Alzheimer's disease).

In more recent years, the study of inflammation has gone deeper into the cell. Cell-signaling molecules have been identified that modulate the expression of genes that control the inflammatory response, including the pro-inflammatory response and the anti-inflammatory response. One of the central regulators that balance the genes encoding anti- and pro-inflammation factors is Nuclear Factor Kappa Beta (NFκB). NFκB is a family of transcriptions factors that include p50 (NFκB1), p52 (NFκB2), p65 (RelA), c-Rel and RelB. These nuclear factors are held as complexes or dimeric pairs in an inactive state in the cytoplasm as a complex by a NFκB inhibitory factor IκB. The IκB proteins include IκBα, IκBβ, and IκBε, but others also exist. The inactive NFκB complex is released from the cytoplasm by phosphorylation of the IκB protein through kinases such as IKKβ. The kinases regulating NFκB activity are activated by immune responses or cellular stresses. Thus, in the cytoplasmic NFκB complex such as IκB/p65/p50, IκB becomes phosphorylated through kinases such as IKKβ and releases dimeric pairs of NFκB to the nucleus such as p65/p50. In the nucleus, NFκB regulates genetic expression of proinflammatory factors such as cytokines like TNFα, IL-6, and IL-1β in addition to enzymes such as cyclooxygenase-2 (COX-2) one of the enzymes that converts arachidonic acid to prostaglandin H2 (PGH2). These factors induce inflammation in various tissues. In addition, depending upon the cellular context and the NFκB nuclear factors released NFκB can cause the expression of anti-inflammatory genes.

Salicylates and other non-steroidal anti-inflammatory drugs (NSAIDs) can influence the NFκB pathway, allowing people to derive relief and reduced inflammation from these drugs. Aspirin and COX inhibitors act to reduce inflammation by reversibly or irreversibly blocking access to the hydrophobic channel via acetylation of serine 530 (COX-1) or Serine 516 (COX-2). For some selective NSAIDs with a carboxylate group, there is significant charge-charge interaction with Arginine 120. This binding or interaction blocks the cyclooxygenase enzyme that forms PGH₂. Salicylate does not irreversibly inhibit cyclooxygenase because it lacks the ability to acylate the COX enzyme and has little, if any, direct inhibitory action on the COX enzyme at concentrations that are relevant in vivo. Salicylate has been shown to inhibit the activity of IKKβ and thereby inhibit NFκB leading to reduced expression of COX-2 in an inflammatory state where COX-2 expression has been induced.

Another example of an NSAID is diflunisal:

Yet another example of an NSAID is triflusal:

Diflunisal and Triflusal are commonly used to relieve pain, tenderness, swelling and stiffness caused by osteoarthritis and rheumatoid arthritis, and to relieve mild to moderate pain generally.

Problems arise in salicylate therapy due to side effects, which means alternative ways need to be developed and pursued to reduce NFκB activity. Some salicylates, when given orally, have a key disadvantage of causing gastric ulcers over the long term in chronic administration. In addition, salicylates can be strong irritants, thought to be caused by the high local concentration of these COX inhibitors. Many of the unwanted effects of aspirin are caused by the inappropriate inhibition of COX or the NFκB pathway. Although NSAIDs inhibit COX and are efficacious anti-inflammatory agents, adverse effects limit their use.

Other anti-inflammatory agents that modulate NFκB activity are omega-3 polyunsaturated fatty acids (PUFA). Omega-3 fatty acids also reduce IL-1, which is an activator of NFκB, and increase anti-inflammatory cytokines, such as IL-10, and adipokines, such as adiponectin. Oily cold water fish, such as salmon, trout, herring, and tuna are the source of dietary marine omega-3 fatty acids with eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) being the key marine derived omega-3 fatty acids. Leafy green vegetables, and certain beans, nuts or oils, such as soybeans, walnuts, flaxseed, and canola oil, are also rich dietary sources of omega-3 fatty acids.

The anti-inflammatory effects of omega-3 fatty acids have been widely studied with positive results for several chronic inflammatory diseases. TNFα and IL-6 are cytokines that increase dramatically during inflammatory processes and are commonly measured as markers of inflammation. Greater intake of omega-3 PUFA has been shown to associate strongly with lower levels of circulating TNFα and IL-6 (Ferrucci, L. et al. J Clin. Endocrinol. Metab. 2006, 91, 439-446). Furthermore, higher intake of omega-3 PUFA has also been associated with increased levels of markers of anti-inflammation, including the well-characterized anti-inflammatory cytokine IL-10 (Ferrucci, L. et al. J. Clin. Endocrinol. Metab. 2006, 91, 439-446). Animal models of colitis indicate that fish oil decreases colonic damage and inflammation, weight loss, and mortality. Fish oil supplements in patients with IBD have shown to modulate levels of inflammatory mediators and may be beneficial for the induction and maintenance of remission in ulcerative colitis.

In the management of RA and other inflammatory conditions, side effects limit the use of NSAIDs. A clinical trial showed that 39 percent of patients with RA supplemented with cod liver oil were able to reduce their daily NSAID requirement by greater than 30 percent. Omega-3 fatty acids have been used to reduce the risk for sudden death caused by cardiac arrhythmias, have been taken as dietary supplements, and the ethyl ester of omega-3 fatty acids as a combination therapy is used to treat dyslipidemia.

Furthermore, omega-3 fatty acids have been shown to improve insulin sensitivity and glucose tolerance in normoglycemic men and in obese individuals. Omega-3 fatty acids have also been shown to improve insulin resistance in obese and non-obese patients with an inflammatory phenotype. Lipid, glucose and insulin metabolism have been show to be improved in overweight hypertensive subjects through treatment with omega-3 fatty acids.

DHA or EPA, C22 and C20 omega-3 fatty acids, are metabolized to active anti-inflammatory metabolites, some of which include resolvins and protectins, and activate various anti-inflammatory pathways.

The ability to simultaneously blunt proinflammatory pathways, for example those that affect levels of C-reactive protein (CRP), TNFα and IL-6 cytokines, while stimulating anti-inflammatory pathways by shunting omega-3 fatty acids, such as DHA and EPA, into metabolic pathways that ultimately produce resolvins, protectins and other metabolites that resolve inflammation would be a great benefit in treating the aforementioned diseases. Inflammation could be particularly vulnerable to a two-pronged attack, inhibiting pro-inflammatory pathways and upregulating anti-inflammatory pathways.

4. SUMMARY OF THE INVENTION

The invention is based in part on the discovery of fatty acid acylated salicylate derivatives and their demonstrated effects in the simultaneous upregulation of anti-inflammatory pathways and down regulation of proinflammatory pathways. The invention is also based in part on the discovery of fatty acid acylated diflunisal derivatives and their upregulation of anti-inflammatory pathways and down regulation of proinflammatory pathways. Additionally, the invention is based in part on the discovery of fatty acid acylated triflusal derivatives and their upregulation of anti-inflammatory pathways and down regulation of proinflammatory pathways. These novel compounds of the invention are useful in the treatment or prevention of diseases associated with inflammation.

DETAILED DESCRIPTION OF THE INVENTION

Inflammation is the underlying cause of and pathological contributor to many chronic diseases including type 2 diabetes, rheumatoid arthritis, psoriasis, inflammatory bowel disease, Parkinson's disease, Alzheimer's disease, multiple sclerosis, epilepsy, and cancer, and the like. Inflammation is the body's natural protective response to insult, injury and infection. The normal inflammatory process is highly regulated. The process is initiated by a stimulus which leads to the induction of pro-inflammatory pathways. The response persists while the stimulus is present and is turned off during the resolving phase of inflammation. During each of these phases of the inflammatory response different enzymes, receptors, and effectors, are activated and inactivated. If the stimulus persists, chronic inflammation ensues and results in an imbalance in the pro- and anti-inflammatory pathways. Current therapies that target inflammation have been directed in general at single molecular targets or effectors in single pathways. For example, TNFα antibodies, TNFα soluble receptors, COX-2 inhibitors, CCR2 antagonists, p38 inhibitors, etc. target just the pro-inflammatory arm of inflammation. In general these approaches are not disease modifying and are associated with side effects that result from an imbalanced inflammatory response. The simultaneous targeting of both the pro- and anti-inflammatory pathways in the normal inflammatory response provides superior activity in targeting inflammation, disease modifying activity, and a reduced side effect profile. The compounds of the invention possess the ability to inhibit pro-inflammatory pathways, while simultaneously activating anti-inflammatory pathways. The simultaneous targeting of these pathways leads to synergistic efficacy and thus the two activities must be delivered to the target cell and/or tissue together.

The compounds of the invention have been designed to bring together salicylate analogs and omega 3 fatty acids into a single molecular conjugate. Salicylate analogs inhibit the pro-inflammatory pathway through inhibition of NFκB. The omega 3 fatty acids including DHA, EPA, and ALA activate the anti-inflammatory pathway. The compounds of the invention thus possess two activities—the ability to blunt pro-inflammatory activity and the ability to activate anti-inflammatory activity compounds of the invention exhibit potert NFκB and TNFα inhibitory activity in a mouse macrophage cell line, RAW264.7, while the individual components, a salicylate analog and a EFA, alone or in combination together, do not. The activity of the compounds of the invention is substantially greater than the sum of the components suggesting that the activity induced by the compounds of the invention is synergistic.

Methods for Using Compounds of the Invention

The invention also includes methods for upregulating an anti-inflammatory pathway and downregulating a proinflammatory pathway in a cell.

In one embodiment, the method comprises contacting a cell with a compound of the invention in an amount sufficient to upregulate an anti-inflammatory pathway and down regulate a proinflammatory pathway in the cell. In general, any cell having, or capable of having, inflammatory activity or capable of expressing NFκB can be used. The cell can be provided in any form. For example, the cell can be provided in vitro, ex vivo, or in vivo. Inflammatory activity can be measured using any method known in the art, e.g., methods as described in Tran P. O. et al Diabetes 2002, 51, 1772-1778. Illustrative examples of cells capable of inflammatory activity include, but are not limited to, immune cells including monocytes, macrophages, T-cell, Th-1, Th-2, Th-17, Treg, lymphocytes, spleen cells, muscle, adipose or fat, vascular cells such as endothelial or pericyte, bone, gum, nerve, brain, glial, astrocytes, nerve, liver, kidney, pancreas including islet cells such as beta cells, lung, heart, breast, bladder, stomach, colon, rectal, small intestine, skin, esophageal, eye, larynx, uterine, ovarian, prostate, tendon, bone marrow, blood, lymph, testicular, vaginal and neoplastic cells.

Also provided in the invention is a method for inhibiting, preventing, or treating inflammation or an inflammatory disease in a subject. The inflammation can be associated with an inflammatory disease or a disease where inflammation contributes to the disease. Inflammatory diseases can arise where there is an inflammation of the body tissue. These include local inflammatory responses and systemic inflammation. Examples of such diseases include, but are not limited to: organ transplant rejection; reoxygenation injury resulting from organ transplantation (see Grupp et al. J. Mol. Cell. Cardiol. 1999, 31, 297-303) including, but not limited to, transplantation of the following organs: heart, lung, liver and kidney; chronic inflammatory diseases of the joints, including arthritis, rheumatoid arthritis, osteoarthritis and bone diseases associated with increased bone resorption; inflammatory bowel diseases such as ileitis, ulcerative colitis, Barrett's syndrome, and Crohn's disease; inflammatory lung diseases such as asthma, adult respiratory distress syndrome, chronic obstructive airway disease, and cystic fibrosis; inflammatory diseases of the eye including corneal dystrophy, trachoma, onchocerciasis, uveitis, sympathetic ophthalmitis and endophthalmitis; chronic inflammatory diseases of the gum, including gingivitis and periodontitis; inflammatory diseases of the kidney including uremic complications, glomerulonephritis and nephrosis; inflammatory diseases of the skin including sclerodermatitis, psoriasis and eczema; inflammatory diseases of the central nervous system, including chronic demyelinating diseases of the nervous system, multiple sclerosis, AIDS-related neurodegeneration and Alzheimer's disease, infectious meningitis, encephalomyelitis, Parkinson's disease, Huntington's disease, amyotrophic lateral sclerosis and viral or autoimmune encephalitis. Metabolic disease such as type II diabetes mellitus; the prevention of type I diabetes; dyslipidemia; hypertriglyceridemia; diabetic complications, including, but not limited to glaucoma, retinopathy, macula edema, nephropathy, such as microalbuminuria and progressive diabetic nephropathy, polyneuropathy, diabetic neuropathy, atherosclerotic coronary arterial disease, peripheral arterial disease, nonketotic hyperglycemichyperosmolar coma, mononeuropathies, autonomic neuropathy, joint problems, and a skin or mucous membrane complication, such as an infection, a shin spot, a candidal infection or necrobiosis lipoidica diabeticorum; immune-complex vasculitis, systemic lupus erythematosus; inflammatory diseases of the heart such as cardiomyopathy, ischemic heart disease hypercholesterolemia, and atherosclerosis; as well as various other diseases that can have significant inflammatory components, including preeclampsia; chronic liver failure, brain and spinal cord trauma, and cancer. The inflammatory disease can also be a systemic inflammation of the body, exemplified by gram-positive or gram negative shock, hemorrhagic or anaphylactic shock, or shock induced by cancer chemotherapy in response to proinflammatory cytokines, e.g., shock associated with proinflammatory cytokines. Such shock can be induced, e.g., by a chemotherapeutic agent that is administered as a treatment for cancer. Other disorders include depression, obesity, allergic diseases, acute cardiovascular events, arrhythmia, prevention of sudden death, muscle wasting diseases such as Duchenne's Muscular Dystrophy, inflammatory myopathies such as dermatomositis, inclusion body myositis, and polymyositis, and cancer cachexia. Also inflammation that results from surgery and trauma can be treated with compound of the invention.

In some embodiments, the subject is administered an effective amount of a compound of the invention.

The invention also includes pharmaceutical compositions useful for treating or preventing an inflammatory disease, or for inhibiting inflammation activity, or more than one of these activities. The compositions can be suitable for internal use and comprise an effective amount of a compound of the invention and a pharmaceutically acceptable carrier. The compounds of the invention are especially useful in that they demonstrate very low peripheral toxicity or no peripheral toxicity.

The compounds of the invention can each be administered in amounts that are sufficient to treat or prevent an inflammatory disease or a reperfusion disease and/or prevent the development thereof in subjects.

Administration of the compounds of the invention can be accomplished via any mode of administration for therapeutic agents. These modes include systemic or local administration such as oral, nasal, parenteral, transdermal, subcutaneous, vaginal, buccal, rectal or topical administration modes.

Depending on the intended mode of administration, the compositions can be in solid, semi-solid or liquid dosage form, such as, for example, injectables, tablets, suppositories, pills, time-release capsules, elixirs, tinctures, emulsions, syrups, powders, liquids, suspensions, or the like, sometimes in unit dosages and consistent with conventional pharmaceutical practices. Likewise, they can also be administered in intravenous (both bolus and infusion), intraperitoneal, subcutaneous or intramuscular form, all using forms well known to those skilled in the pharmaceutical arts.

Illustrative pharmaceutical compositions are tablets and gelatin capsules comprising a compound of the invention and a pharmaceutically acceptable carrier, such as: a) a diluent, e.g., purified water, triglyceride oils, such as hydrogenated or partially hydrogenated vegetable oil, or mixtures thereof, corn oil, olive oil, sunflower oil, safflower oil, fish oils, such as EPA or DHA, or their esters or triglycerides or mixtures thereof, omega-3 fatty acids or derivatives thereof, lactose, dextrose, sucrose, mannitol, sorbitol, cellulose, sodium, saccharin, glucose and/or glycine; b) a lubricant, e.g., silica, talcum, stearic acid, its magnesium or calcium salt, sodium oleate, sodium stearate, magnesium stearate, sodium benzoate, sodium acetate, sodium chloride and/or polyethylene glycol; for tablets also; c) a binder, e.g., magnesium aluminum silicate, starch paste, gelatin, tragacanth, methylcellulose, sodium carboxymethylcellulose, magnesium carbonate, natural sugars such as glucose or beta-lactose, corn sweeteners, natural and synthetic gums such as acacia, tragacanth or sodium alginate, waxes and/or polyvinylpyrrolidone, if desired; d) a disintegrant, e.g., starches, agar, methyl cellulose, bentonite, xanthan gum, alginic acid or its sodium salt, or effervescent mixtures; e) absorbent, colorant, flavorant and sweetener; f) an emulsifier or dispersing agent, such as Tween 80, Labrasol, HPMC, DOSS, caproyl 909, labrafac, labrafil, peceol, transcutol, capmul MCM, capmul PG-12, captex 355, gelucire, vitamin E TGPS or other acceptable emulsifier; and/or g) an agent that enhances absorption of the compound such as cyclodextrin, hydroxypropyl-cyclodextrin, PEG400, PEG200.

Liquid, particularly injectable, compositions can, for example, be prepared by dissolution, dispersion, etc. For example, the compound of the invention is dissolved in or mixed with a pharmaceutically acceptable solvent such as, for example, water, saline, aqueous dextrose, glycerol, ethanol, and the like, to thereby form an injectable isotonic solution or suspension. Proteins such as albumin, chylomicron particles, or serum proteins can be used to solubilize the compounds of the invention.

The compounds of the invention can be also formulated as a suppository that can be prepared from fatty emulsions or suspensions; using polyalkylene glycols such as propylene glycol, as the carrier.

The compounds of the invention can also be administered in the form of liposome delivery systems, such as small unilamellar vesicles, large unilamellar vesicles and multilamellar vesicles. Liposomes can be formed from a variety of phospholipids, containing cholesterol, stearylamine or phosphatidylcholines. In some embodiments, a film of lipid components is hydrated with an aqueous solution of drug to a form lipid layer encapsulating the drug, as described in U.S. Pat. No. 5,262,564, the conterts of which are herein incorporated by reference in their entirety.

compounds of the invention can also be delivered by the use of monoclonal antibodies as individual carriers to which the compounds of the invention are coupled. The compounds of the invention can also be coupled with soluble polymers as targetable drug carriers.

Effects of Compounds of the Invention on Insulin Signaling in 3T3-L1 Adipocytes

3T3-L1 adipocytes are serum starved for 16 hours and treated or not treated with 5 mM aspirin for 2 hours and either 6.0 nM mTNFα (20 minutes) or the phosphatasen inhibitor calyculin A (Axxora, San Diego, USA) (at 2.0 nM for 30 minutes) as described in Yuan, M. et al.

IL-10 levels are normalized to the house-keeping gene GAPDH, which was measured using the same method. IL-10 levels in compound of the invention treated samples are expressed as a fold increase over IL-10 levels in Vehicle treated samples. (**p<0.005 by 2-tailed t-test).

Example 6
TNFα Release Assay in RAW 264.7 Macrophages

The purpose of this assay is to measure the ability of small molecules to inhibit the secretion of TNFα in cultured macrophages stimulated with lipopolysaccharide (LPS). Treatment of macrophages with LPS activates inflammatory cytokine pathways primarily through the TLR4-NFκB signaling axis. Compounds of the invention inhibit the transcriptional activation of NFκB and thus decrease the production and release of TNFα. Dexamethasone, a potert agonist of the glucocorticoid receptor is used a positive control for inhibition of TNFα release.

Day 1: Seed RAW 264.7 macrophages into 96 well culture plates. Remove culture media from RAW 264.7 cell growing in a 75 mm²tissue culture flask (cells should be at ˜70% confluence) and add 10 mL of warmed complete growth media (DMEM+10% FBS+1× pen/step). The cells are scraped into suspension using a sterile plate scraper and homogenized by pipetting up and down with a 10 mL serological pipette. The cell concentration is determined using a clinical hematoctyometer. Cells are then diluted to 150,000 cells per mL into growth media. The diluted cells are then transferred to a sterile reagent reservoir and 100 μl of cell suspension is pipetted into each well of a 96 well culture plate using a multichannel pipette (15,000 cells/well). Plates are then incubated at 37° C. under normal tissue culture growth conditions (37° C., humidified CO₂chamber).

Day 2: The test compound sample plate is prepared. Test compounds are prepared in growth media. Compounds are delivered to media from 1000× stocks in 100% DMSO (e.g. for a 10 μM final concentration of test compound, deliver 2 μl of 10 mM test compound to 2 mL of media). At least 150 μl of 1× compound in media is added to 96 well sample plate. The perimeter wells of the 96 well plate are not used to avoid edge effects. Twelve sample wells are prepared with media plus 0.1% DMSO (these samples will serve as the vehicle controls; LPS-stimulated and non-stimulated; 10 μM dexamethasone, is used as a positive control). Culture plates are then returned to the growth incubator for 2 hours. Cells are stimulated afterwards by adding 25 μl of 50 ng/mL LPS is added to every well (except the 6 unstimulated vehicle control wells: final concentration of 10 ng/mL LPS. Plates are returned to growth incubator for 3 hours. Afterwards, 100 μl of media supernatant is removed and transferred to a 96 well v-bottom sample plate. The media supernatant plate is centrifuged for 5 minutes at 1,000 rpm in a swing-bucket centrifuge, pelleting any cellular debris that may remain in supernatant. 80 μl of supernatant is removed from sample plate and transferred to a fresh v-bottom 96 well plate. Cell viability is measured using Celltiter-glo kit. By measuring cell viability, a given compound's effects on TNFα secretion can determine whether effects are due to cytotoxicity or to true inhibition of inflammatory signaling. Add 100 μl of Celltiter-glo reagent to each well of the cell culture plate and afterwards measure the luminescence signal (CPS) of the plate using the Victor 5 plate reader (0.3 second read; 60 second plate shaking prior to read). Cell viability of a given compound at a given concentration is computed as follows:

Cell viability=CPS Sample/(Average CPS unstimulated controls)*100

Use 20 μl of media supernatant per well for TNFα ELISA. Follow Invitrogen/Biosource manufacture's protocol for the mouse TNFα ELISA. Chromogen development is typically conducted for 20-30 minutes as described in the manufacturer's protocol. After addition of stop solution, measure OD 450 nm using the Victor 5 plate reader (0.1 second/well scan). Determine the TNFα secretion percent of control. The following formula is used to determine the TNFα secretion percent of control:

$\frac{\begin{matrix} 100 \times (OD 450 nm Sample X) - \\ (Average OD 450 nm unstimulated vehicle controls) \end{matrix}}{\begin{matrix} (Average OD 450 nm LPS stimulated vehicle controls) - \\ (Average OD 450 nm unstimulated vehicle controls) \end{matrix}}$

For each test compound, TNFα secretion percent of control can be plotted as a function of compound concentration using a four parameter dose-response curve fit equation (XLFIT Model #205):

fit=(A+((B−A)/(1+((C/x)^D))))
inv=(C/((((B−A)/(y−A))−1)^(1/D)))
res=(y−fit)

For compounds which cause greater than 50% inhibition of TNFα secretion, determine the IC₅₀(concentration of compound which causes 50% inhibition of TNFα secretion A sample graph showing the data obtained by using Compounds III-1, Ih-2 and III-6 in the procedure described above in Example 6 is shown in FIG. 2.

As seen in FIG. 2, salicylate alone, fatty acid alone, and the simple combination of salicylate and fatty acid administered together do not appreciably inhibit the production of TNFα. In contrast the fatty acid acylated salicylate significantly inhibits the production of TNFα. This demonstrates that the fatty acid acylated salicylate is the species responsible for the inhibition of TNFα production and not either of the individual components alone or in simple combination.

A sample table showing the data obtained by using additional compounds of the invention in the procedure described above in Example 6 is shown in Table 1, below:

In Vivo Effects of Compounds of the Invention in an LPS-Challenge TNFα Mouse Model

To measure the effects of compounds on TNFα secretion in vivo, Male Swiss Webster mice (n=10 animals per group) are dosed by oral gavage with each test compound. All compounds are formulated in an aqueous solution of 0.5% carboxymethylcellulose and 0.05% TWEEN-80 (Vehicle). One hour after compound dosing, animals are treated with 0.2 mg/kg LPS (lipopolysaccharide) by intraperitoneal (IP) injection. Ninety minutes after LPS challenge, mice are anesthetized and bled by cardiac puncture into serum separator tubes (with sodium heparin). Bleeds are allowed to clot at room temperature for 2 hours, and tubes are then spun for 20 minutes at 2,000×g. Serum is harvested from tubes (100-150 μl per animal) and frozen at −70° C. TNFα serum levels are measured using commercially available TNFα ELISA kits (*p<0.05 using a 2-tailed t-test). A sample graph showing the data obtained by using Compound III-1 in the procedure described above in Example 7 is shown in FIG. 3.

Example 8
Effects of Compounds of the Invention on NFκB Levels in RAW 264.7 Macrophages

RAW 264.7 cells transfected with an NFκB-driven luciferase reporter are plated in 96 well plates. Cells are treated with Vehicle (0.1% ethanol) or test compounds for 2 hours. As a positive control for inhibition of NFκB signaling, 6 wells are treated with 10 μM dexamethasone. Cells are then challenged with 200 ng/mL LPS for 3 hours in the presence of test compounds. A subset of wells treated with vehicle should remain unstimulated with LPS to determine the floor signal of the assay. NFκB driven luciferase activity is developed by addition of BriteLite luciferase kit (Perkin-Elmer) and measured using a Victor V plate reader. NFκB activity (luciferase activity) for each treatment was normalized to Vehicle wells treated with LPS (% NFκB Response). AlamarBlue was used to monitor cell viability to ensure that inhibition of luciferase signal was not a result of compound cytotoxicity.

A sample table showing the data obtained by using additional compounds of the invention in the procedure described above in Example 8 is shown in Table 2, below:

Luciferase Activity of NF-κB Reporter Gene in RAW Cells

RAW 264.7 cells stably expressing a 3×NF-κB response element-driven luciferase reporter were seeded into 96 well plates. After 18 hours, cells were pre-treated with compounds of the invention for 2 hours, and then stimulated with LPS (lipopolysaccharide, 200 ng/mL) or vehicle control for 3 h in the presence of the compounds of the invention. A set of six vehicle was left unstimulated with LPS in order to measure the assay floor. AlamarBlue viability dye (Invitrogen) was added to cells simultaneously with the delivery of LPS (final AlamarBlue concentration of 10%). After the 3 h incubation period with LPS, cell viability was measured by reading fluorescence (excitation 550 nm, emission 595 nm) with a Perkin Elmer Victor V plate reader. Then cell media was aspirated from each well. Luciferase signal was then developed by addition of the Britelite Plus reagent (Perkin Elmer).
