3. BACKGROUND OF THE INVENTIONInflammatory 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 proinflammation 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 IκBa, 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 IkB/p65/p50, IkB 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 ain 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 et al., 2006). Furthermore, higher intake of omega-3 PUFA has also been associated with increased levels of markers of anttinflammation, including the well-characterized anti-inflammatory cytokine IL-10 (Ferruccci et al, 2006). 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 INVENTIONThe invention is based in part on the discovery of Fatty Acid Acetylated 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 Acetylated 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 Acetylated Triflusal Derivatives and their upregulation of anti-inflammatory pathways and down regulation of proinflammatory pathways. These novel compounds are useful in the treatment or prevention of diseases associated with inflammation.

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, etc. 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 potent 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.

It is to be understood that the examples are provided to illustrate certain embodiments and that no limitation to the scope of the disclosure is intended thereby. It is to be further understood that resort may be had to various other embodiments, modifications, and equivalents thereof which may suggest themselves to those skilled in the art without departing from the spirit of the present disclosure and/or scope of the appended claims.
Example 1: Effect of Illustrative Compounds of the Invention on Inflammatory Activity in Adipose Tissue in MiceDemonstration of the ability of illustrative Compounds of the Invention to mediate serum adiponectin concentrations in a rodent obesity model was shown using methods described in Itoh, M., et al., Arterioscler. Thromb. Vasc. Biol. 2007 27(9):1918-25. Male C57BL/6J ob/ob mice and their wild-type (WT) littermates are purchased from Charles River Laboratories (Wilmington, Mass.). The animals are housed in individual cages in a temperature- , humidity- , and light-controlled room (12-hour light and 12-hour dark cycle) and allowed free access to water and fish meal-free diet (fish meal-free F1 (Funabashi Farm, Chiba, Japan) supplemented with; 362 kcal/100 g, 4.4% energy as fat).
Six-week-old male ob/ob mice and WT littermates are allowed unrestricted access to the fish meal-free diet (control group) or fish meal-free diet supplemented with 5% EPA (wt/wt) (EPA-treated group) for 4 weeks (n=10 to 14). In the short-term administration protocol, 8-week-old male ob/ob mice are treated with the Compound of the Invention for 2 weeks (n=7 to 8). All diets are changed every day and served with nonmetallic feeder to prevent oxidization of fatty acids. At the end of the experiments, mice are euthanized after 5-hour starvation under intraperitoneal pentobarbital anesthesia (30 mg/kg). Blood glucose and serum concentrations of triglyceride (TG) and free fatty acid (FFA) are measured as described in Kouyama R, et al., Endocrinology, 146: 3481-3489, 2005. Serum fatty acid and salicylate concentrations are measured by gas chromatography.
Example 2: In Vivo Effects of Compounds of the Invention in Zucker Fatty Rats and Ob/Ob MiceTwelve-week-old male Zucker fa/fa rats and 8-week-old ob/ob (Lepob/ob) and ob/1 mice are given free access to food and water. A Compound of the Invention (120 mg/kg/day) is dosed orally by gavage once per day. For glucose tolerance tests, glucose (2.0 g/kg) is administered by oral gavage (rats) or intraperitoneal injection (mice) after an overnight fast. Blood glucose and serum insulin concentrations are determined during oral glucose tolerance tests in Zucker fa/fa rats or fall rats. For insulin tolerance tests, insulin (2.0 U/kg) is injected intraperitoneally after an overnight fast. Cholesterol, triglyceride, long-chain FFA, and ALT concentrations are measured in sera from fasting Zucker fa/fa rats.
Example 3: Effects of Compounds of the Invention on Insulin Signaling in 3T3-L1 Adipocytes3T3-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 min) or the phosphatasen inhibitor calyculin A (Axxora, San Diego, USA) (at 2.0 nM for 30 min) as described in Yuan, M., et al., Science, 293, 1673-1677, 2001. After a 5-min stimulation with 10 nM insulin, the cells are chilled and solubilized and proteins are immunoprecipitated with anti-IR or anti-IRS1. Proteins are separated by SDS-PAGE and identified by Western blotting with anti-pY, anti-IR, or anti-IRS 1.
Example 4: Effects of Compounds of the Invention on IL-10 Levels in 3T3-L1 AdipocytesIL-10 production in 3T3-L1 adipocytes is measured using a modification of the method described by Bradley et al, Obesity (2008) 16, 938-944. Fully differentiated 3T3-L1 adipocytes are serum starved for 18 hours in DMEM containing 0.2% fatty acid free bovine serum albumin (BSA) and 0.1 mM pyruvate. A stock of 5 mM test compound is prepared in 100% ethanol and then is diluted 1:100 in 2% fatty acid free BSA in DMEM (with 0.1 mM pyruvate), yielding a 50 μM solution of compound. Starvation media is removed from cells and is replaced by the 50 μM compound solution in DMEM or Vehicle (0.1% ethanol, 0.2% fatty acid free BSA in DMEM with 0.1 mM pyruvate). Test compound or Vehicle is incubated with cells for 48 hours. Subsequently, RNA is purified from cells and reverse transcribed to cDNA. IL-10 message levels are then measured by quantitative real-time PCR (Applied Biosystems Step-One) using gene-specific oligoneucleotide primers and fluorescently labeled probe. 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). A sample graph showing the data obtained by using one of the Compounds of the Invention described above in Example 4 is shown in
Fao cells are serum starved for 16 hours followed by 2-hour incubations at 37° C. with 5 mM-25 mM a Compound of the Invention according to the method described in Yuan, M., et al., Science, 293, 1673-1677, 2001. Cells are then stimulated sequentially with 6.0 nM mTNFα for 20 min. and 10 nM insulin for 5 min. Cells are chilled and solubilized and proteins are then immunoprecipitated with anti-IR and detected by Western blotting using anti-pY. Phosphorylation is quantified by densitometry.
Example 6: TNFα Release Assay in RAW 264.7 MacrophagesThe 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 potent 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 mm2 tissue 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 CO2 chamber).
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. Note: 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 1000 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:
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).

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 2000×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 some of the Compounds of the Invention in the procedure described above in Example 7 is shown in
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.
