[0055] In one embodiment, the liver condition is high cholesterol, alcoholic liver disease (including acute alcoholic hepatitis), cirrhosis, cysts, primary biliary cirrhosis, fatty liver disease (NAFLD), fibrosis, jaundice, primary sclerosing cholangitis (PSC), hemochromatosis, primary biliary cirrhosis, Alpha-1 Antitrypsin Deficiency or drug induced liver injury (e.g. caused by antimicrobials, cardiovascular, CNS agents, antineoplastic and analgesic (acetaminophen). See Am J Gastroenterol 2014; 109:950-966; doi:10.1038/ajg.2014.131 ; published online 17 June 2014 which is incorporated by reference. [0056] In one aspect, liver damage is determined by standard liver function tests and or by imaging (CT, X-Ray, MRI etc.). Liver function tests include bilirubin, ammonia, gamma-glutamyl transferase (GGT), alanine aminotransferase (ALT or SGPT), aspartate aminotransferase (AST or SGOT), and alkaline phosphatase (ALP).

[0057] Non-alcoholic fatty liver disease (NAFLD) and non-alcoholic steatohepatitis (NASH)

[0058] NAFLD and its more severe form NASH are associated with several diseases (obesity, type 2 diabetes, dyslipidaemia and hypertension), having insulin resistance as the common factor. These conditions cluster to form the insulin resistance or metabolic syndrome, carrying a high risk for cardiovascular complications. NASH itself, as well as pure fatty liver, is an insulin-resistant state, not only in subjects with additional metabolic disorders, but also in lean subjects.

[0059] Because the histopathology of NASH resembles that of alcohol-induced steatohepatitis (ASH), these 2 conditions share common pathogenic aspects. Immunological mechanisms play a pivotal role in the pathogenesis of ASH. This has been well demonstrated by studies of patients and experimental animals. In hospitalized patients with severe ASH and NASH, serum levels of several pro-inflammatory cytokines, including TNF- a, are increased significantly. Cytokine levels correlate well with liver disease severity. [0060] While it is widely acknowledged that TNF-a expression increases in obesity, the mechanisms driving chronic overproduction of TNF-a in obese humans remain obscure. However, the resultant chronic inflammatory state has been implicated in the pathogenesis of the metabolic syndrome that often accompanies obesity. The immunopathogenesis of obesity-related NASH has been studied extensively in the ob/ob mice model. The studies clearly demonstrate that cytokine producing cells in ob/ob livers are Th1 polarized. This microenvironment favours the perpetuation of inflammatory signals. Inhibiting TNFa significantly reduced the hepatic activities of both kinases, thereby supporting the concept that excessive TNFa activity contributes to hepatic insulin resistance in leptin-deficient mice. A strong positive correlation has been noted between hepatic insulin resistance and NASH in many experimental animals and humans.

[0061 ] NAFLD and NASH are initially suspected if blood tests show high levels of liver enzymes. An ultrasound is typically used to confirm the NAFLD diagnosis.

[0062] In one aspect, in the uses and methods as described herein the NASH or NAFLD patient may be treated orally with the compounds of the present description may be used in order to prevent, control or reduce liver damage.

[0063] In one aspect, in the uses and methods as described herein the patient is a NASH or NAFLD patient that has developed cirrhosis.

[0064] In one aspect, in the uses and methods as described herein the NASH or NAFLD patient is overweight or obese, has diabetes, high cholesterol or high triglycerides.

[0065] High Cholesterol [0066] High blood cholesterol levels are associated with increased risk of suffering from heart attack and stroke.

[0067] In one aspect, the patient is a patient having elevated blood cholesterol levels.

[0068] In one aspect, an elevated cholesterol level is a total blood cholesterol level that exceeds 200 mg/dL, that exceeds 220 mg/dL or that exceeds 240 mg/dL.

[0069] Alcoholic Liver Disease (ALD)

[0070] Alcoholic liver disease occurs after years of heavy drinking. Alcohol can cause inflammation in the liver. ALD has three stages: 1 ) alcoholic fatty liver disease; 2) alcoholic hepatitis and 3) Cirrhosis.

[0071 ] Alcoholic hepatitis (not related to infectious hepatitis) is the second, more serious stage of ALD. It occurs when alcohol misuse over a longer period causes the tissues of the liver to become inflamed. [0072] Damage caused by alcoholic fatty liver disease or Alcoholic hepatitis can usually be reversed if the use of alcohol is stopped.

[0073] Cirrhosis is the final stage of alcohol-related liver disease, which occurs when the liver becomes significantly scarred. Cirrhosis is generally not reversible, but stopping drinking alcohol can prevent further damage and significantly increase life expectancy.

[0074] In one aspect the ALD is diagnosed with blood test, liver biopsy or imagery (ultrasound scan, computerised tomography (CT) scan).

[0075] In one aspect, in the uses and methods as described herein the ALD patient may be treated with the compounds of the present description to prevent, control or reduce liver damage.

[00761 Cirrhosis

[0077] Cirrhosis is scarring of the liver caused by many forms of liver diseases and conditions, such as hepatitis and chronic alcohol abuse. [0078] In one aspect the ALD is diagnosed with blood test, liver biopsy or imagery (ultrasound scan, computerised tomography (CT) scan).

[0079] In one aspect, in the uses and methods as described herein the cirrhosis patient may be treated with the compounds of the present description in order to prevent, control or reduce liver damage. [00801 Cysts

[0081 ] Cysts are thin-walled structures that contain fluid. Most cysts are single, although some patients may have several. The symptoms associated with liver cysts include upper abdominal fullness, discomfort, or pain.

[0082] The cysts are usually found by ultrasound (US) or computed tomography (CT scan).

[0083] In one aspect, in the uses and methods as described herein the cysts patient may be treated with the compounds of the present description in order to prevent, control or reduce the cysts and/or the symptoms associated with liver cysts.

[0084] Fibrosis

[0085] Liver fibrosis is the scarring process that represents the liver's response to injury.

[0086] Liver fibrosis is usually found by biopsy.

[0087] In one aspect, in the uses and methods as described herein the liver fibrosis patient may be treated with the compounds of the present description in order to prevent, reduce or control liver fibrosis or inflammation associated/caused by liver fibrosis.

[0088] Intra-Hepatic or post-hepatic jaundice

[0089] There are three types of jaundice depending on what is causing disruption to the normal removal of bilirubin from the body.

[0090] In one aspect, in the uses and methods as described herein the jaundice patient is a patient that suffers from: intra-hepatic jaundice (also known as hepatocellular jaundice) - the disruption occurs inside the liver. This can be caused by conditions such as Gilbert's syndrome, cirrhosis or other liver damage. post-hepatic jaundice (also known as obstructive jaundice) - the disruption prevents the bile (and the bilirubin inside it) from draining out of the gallbladder and into the digestive system. This can be caused by conditions such as gallstones or tumours.

[0091 ] In one aspect, in the uses and methods as described herein the intrahepatic or post-hepatic patient may be treated with the compounds of the present description in order to control, reduce or prevent liver damage.

[0092] In one aspect, in the uses and methods as described herein the jaundice patient suffers from intra-hepatic jaundice.

[0093] Primary sclerosing cholangitis (PSC) [0094] PSC is a disease of the bile ducts. The term "cholangitis" in primary sclerosing cholangitis refers to inflammation of the bile ducts, while the term "sclerosing" describes the hardening and scarring of the bile ducts that result from chronic inflammation. [0095] Primary sclerosing cholangitis is a progressive disease that leads to liver damage and, eventually, liver failure.

[0096] In one aspect, in the uses and methods as described herein the PSC patient mayl be treated with the compounds of the present description in order to reduce, control, or prevent liver damage. [0097] Hemochromatosis

[0098] Hemochromatosis is an hereditary condition characterised in an excess on iron absorption. The excess iron is stored in organs, especially liver, heart and pancreas. The excess iron can poison these organs, leading to life- threatening conditions such as cancer, heart arrhythmias and cirrhosis. [0099] In one aspect, in the uses and methods as described herein the PSC patient may be treated with the compounds of the present description in order to control, prevent or reduce liver damage.

[00100] Alpha-1 Antitrypsin Deficiency

[00101 ] The genetic defect in alphal -antitrypsin (AAT) deficiency alters the configuration of the alphal -antitrypsin molecule and prevents its release from hepatocytes. As a result, serum levels of alphal -antitrypsin are decreased, leading to low alveolar concentrations, where the alphal - antitrypsin molecule normally would serve as protection against antiproteases. The resulting protease excess in alveoli destroys alveolar walls and causes emphysema. The accumulation of excess alphal -antitrypsin in hepatocytes can also lead to destruction of these cells and ultimately, clinical liver disease.

[00102] In one aspect, in the uses and methods as described herein the AAT patient may be treated orally with the compounds of the present description in order to prevent, control or reduce liver damage. [00103] Primary Biliary Cirrhosis (PBC)

[00104] PBC is a slow, chronic liver disease which can cause progressive destruction of the bile ducts in the liver. The body attacks the cells lining the bile ducts within the liver as if they are foreign to the body itself. This damage causes poor drainage of bile acids, which leak outwards and damage the normal liver cells. This causes inflammation and scarring which may, after many years become extensive. This widespread damage and scarring is commonly called cirrhosis.

[00105] PBC usually diagnosed with blood tests. The presence of AMA (antimitochondrial antibody) is indicative of PBC.

[00106] In one aspect, in the uses and methods as described herein the PBC patient may be treated with the compounds of the present description in order to prevent, control or reduce liver damage.

[00107] In one aspect, in the uses and methods as described herein the PBC patient has tested positive for AMA.

[00108] Sepsis

[00109] Sepsis is a potentially life-threatening complication of an infection. Sepsis occurs when endotoxins such as LPS are released into the bloodstream, triggering an inflammatory response throughout the body. This inflammation can trigger a cascade of changes that can damage multiple organ systems, causing them to fail. If sepsis progresses to septic shock, blood pressure drops dramatically, which may lead to death.

[001 10] In one aspect, the compounds of the present description may be used to treat sepsis.

[001 1 1 ] In one aspect, in the uses and methods as described herein the sepsis patient may be treated with the compounds of the present description in order to prevent, control or reduce the risks associated to a septic shock.

Formulations [001 12] As used herein, the term "effective amount" means that amount of a drug or pharmaceutical agent that will elicit the biological or medical response of a tissue, system, animal or human that is being sought, for instance, by a researcher or clinician. Furthermore, the term "therapeutically effective amount" means any amount which, as compared to a corresponding subject who has not received such amount, results in improved treatment, healing, prevention, or amelioration of a disease, disorder, or side effect, or a decrease in the rate of advancement of a disease or disorder. The term also includes within its scope amounts effective to enhance normal physiological function.

[001 13] As used herein, the terms "treatment," "treat," and "treating" refer to reversing, alleviating, delaying the onset of, or inhibiting the progress of a disease or disorder, or one or more symptoms thereof, as described herein. In some embodiments, treatment may be administered after one or more symptoms have developed. In other embodiments, treatment may be administered in the absence of symptoms. For example, treatment may be administered to a susceptible individual prior to the onset of symptoms (e.g., in light of a history of symptoms and/or in light of genetic or other susceptibility factors). Treatment may also be continued after symptoms have resolved, for example to prevent or delay their recurrence.

[001 14] The term "patient or subject" as used herein refers to a mammal. A subject therefore refers to, for example, dogs, cats, horses, cows, pigs, guinea pigs, and the like. Preferably the subject is a human. When the subject is a human, the subject may be either a patient or a healthy human. [001 15] In some embodiments, the therapeutically effective amount of a compound as defined herein, or a pharmaceutically acceptable salt thereof, can be administered to a patient alone or admixed with a pharmaceutically acceptable carrier.

[001 16]The term "pharmaceutically acceptable carrier, adjuvant, or vehicle" refers to a non-toxic carrier, adjuvant, or vehicle that does not destroy the pharmacological activity of the compound with which it is formulated. Pharmaceutically acceptable carriers, adjuvants or vehicles that may be used in the compositions of this disclosure include, but are not limited to, ion exchangers, alumina, aluminum stearate, lecithin, serum proteins, such as human serum albumin, buffer substances such as phosphates, glycine, sorbic acid, potassium sorbate, partial glyceride mixtures of saturated vegetable fatty acids, water, salts or electrolytes, such as protamine sulfate, disodium hydrogen phosphate, potassium hydrogen phosphate, sodium chloride, zinc salts, colloidal silica, magnesium trisilicate, polyvinyl pyrrolidone, cellulose- based substances, polyethylene glycol, sodium carboxymethylcellulose, polyacrylates, waxes, polyethylene-polyoxypropylene-block polymers, polyethylene glycol and wool fat.

[001 17]A "pharmaceutically acceptable derivative" means any non-toxic salt, ester, salt of an ester or other derivative of a compound of the present description that, upon administration to a recipient, is capable of providing, either directly or indirectly, a compound of the present description or an inhibitory active metabolite or residue thereof.

[001 18]Compositions described herein may be administered orally, parenterally, by inhalation spray, topically, rectally, nasally, buccally, vaginally or via an implanted reservoir. The term "parenteral" as used herein includes subcutaneous, intravenous, intramuscular, intra- articular, intra-synovial, intrasternal, intrathecal, intrahepatic, intralesional and intracranial injection or infusion techniques.

[001 19]Liquid dosage forms for oral administration include, but are not limited to, pharmaceutically acceptable emulsions, microemulsions, solutions, suspensions, syrups and elixirs. In addition to the active compounds, the liquid dosage forms may contain inert diluents commonly used in the art such as, for example, water or other solvents, solubilizing agents and emulsifiers such as ethyl alcohol, isopropyl alcohol, ethyl carbonate, ethyl acetate, benzyl alcohol, benzyl benzoate, propylene glycol, 1 ,3-butylene glycol, dimethylformamide, oils (in particular, cottonseed, groundnut, corn, germ, olive, castor, and sesame oils), glycerol, tetrahydrofurfuryl alcohol, polyethylene glycols and fatty acid esters of sorbitan, and mixtures thereof. Besides inert diluents, the oral compositions can also include adjuvants such as wetting agents, emulsifying and suspending agents, sweetening, flavoring, and perfuming agents.

[00120] Injectable preparations, for example, sterile injectable aqueous or oleaginous suspensions may be formulated according to the known art using suitable dispersing or wetting agents and suspending agents. The sterile injectable preparation may also be a sterile injectable solution, suspension or emulsion in a nontoxic parenterally acceptable diluent or solvent, for example, as a solution in 1 ,3-butanediol. Among the acceptable vehicles and solvents that may be employed are water, Ringer's solution, U.S. P. and isotonic sodium chloride solution. In addition, sterile, fixed oils are conventionally employed as a solvent or suspending medium. For this purpose any bland fixed oil can be employed including synthetic mono- or diglycerides. In addition, fatty acids such as oleic acid are used in the preparation of injectables.

[00121 ] Injectable formulations can be sterilized, for example, by filtration through a bacterial -retaining filter, or by incorporating sterilizing agents in the form of sterile solid compositions which can be dissolved or dispersed in sterile water or other sterile injectable medium prior to use.

[00122] In order to prolong the effect of a provided compound, it is often desirable to slow the absorption of the compound from subcutaneous or intramuscular injection. This may be accomplished by the use of a liquid suspension of crystalline or amorphous material with poor water solubility. The rate of absorption of the compound then depends upon its rate of dissolution that, in turn, may depend upon crystal size and crystalline form. Alternatively, delayed absorption of a parenterally administered compound form is accomplished by dissolving or suspending the compound in an oil vehicle. Injectable depot forms are made by forming microencapsule matrices of the compound in biodegradable polymers such as polylactide-polyglycolide. Depending upon the ratio of compound to polymer and the nature of the particular polymer employed, the rate of compound release can be controlled. [00123]Examples of other biodegradable polymers include poly(orthoesters) and poly(anhydrides). Depot injectable formulations are also prepared by entrapping the compound in liposomes or microemulsions that are compatible with body tissues.

[00124]Compositions for rectal or vaginal administration are preferably suppositories which can be prepared by mixing the compounds of the present description with suitable non-irritating excipients or carriers such as cocoa butter, polyethylene glycol or a suppository wax which are solid at ambient temperature but liquid at body temperature and therefore melt in the rectum or vaginal cavity and release the active compound. [00125]Solid dosage forms for oral administration include capsules, tablets, pills, powders, and granules. In such solid dosage forms, the active compound is mixed with at least one inert, pharmaceutically acceptable excipient or carrier such as sodium citrate or dicalcium phosphate and/or a) fillers or extenders such as starches, lactose, sucrose, glucose, mannitol, and silicic acid, b) binders such as, for example, carboxymethylcellulose, alginates, gelatin, polyvinylpyrrolidinone, sucrose, and acacia, c) humectants such as glycerol, d) disintegrating agents such as agar-agar, calcium carbonate, potato or tapioca starch, alginic acid, certain silicates, and sodium carbonate, e) solution retarding agents such as paraffin, f) absorption accelerators such as quaternary ammonium compounds, g) wetting agents such as, for example, cetyl alcohol and glycerol monostearate, h) absorbents such as kaolin and bentonite clay, and i) lubricants such as talc, calcium stearate, magnesium stearate, solid polyethylene glycols, sodium lauryl sulfate, and mixtures thereof. In the case of capsules, tablets and pills, the dosage form may also comprise buffering agents.

[00126]Solid compositions of a similar type may also be employed as fillers in soft and hard-filled gelatin capsules using such excipients as lactose or milk sugar as well as high molecular weight polyethylene glycols and the like. The solid dosage forms of tablets, dragees, capsules, pills, and granules can be prepared with coatings and shells such as enteric coatings and other coatings well known in the pharmaceutical formulating art. They may optionally contain opacifying agents and can also be of a composition that they release the active ingredient(s) only, or preferentially, in a certain part of the intestinal tract, optionally, in a delayed manner. Examples of embedding compositions that can be used include polymeric substances and waxes. Solid compositions of a similar type may also be employed as fillers in soft and hard-filled gelatin capsules using such excipients as lactose or milk sugar as well as high molecular weight polyethylene glycols and the like.

[00127] Provided compounds can also be in micro-encapsulated form with one or more excipients as noted above. The solid dosage forms of tablets, dragees, capsules, pills, and granules can be prepared with coatings and shells such as enteric coatings, release controlling coatings and other coatings well known in the pharmaceutical formulating art. In such solid dosage forms the active compound may be admixed with at least one inert diluent such as sucrose, lactose or starch. Such dosage forms may also comprise, as is normal practice, additional substances other than inert diluents, e.g., tableting lubricants and other tableting aids such a magnesium stearate and microcrystalline cellulose. In the case of capsules, tablets and pills, the dosage forms may also comprise buffering agents. They may optionally contain opacifying agents and can also be of a composition that they release the active ingredient(s) only, or preferentially, in a certain part of the intestinal tract, optionally, in a delayed manner. Examples of embedding compositions that can be used include polymeric substances and waxes. [00128]Dosage forms for topical or transdermal administration of a compound of the present description include ointments, pastes, creams, lotions, gels, powders, solutions, sprays, inhalants or patches. The active component is admixed under sterile conditions with a pharmaceutically acceptable carrier and any needed preservatives or buffers as may be required. Ophthalmic formulation, ear drops, and eye drops are also contemplated as being within the scope of the present description. Additionally, the description contemplates the use of transdermal patches, which have the added advantage of providing controlled delivery of a compound to the body. Such dosage forms can be made by dissolving or dispensing the compound in the proper medium. Absorption enhancers can also be used to increase the flux of the compound across the skin. The rate can be controlled by either providing a rate controlling membrane or by dispersing the compound in a polymer matrix or gel.

[00131 ]The amount of provided compounds that may be combined with carrier materials to produce a composition in a single dosage form will vary depending upon the patient to be treated and the particular mode of administration. Provided compositions may be formulate such that a dosage of between 0.01 - 100 mg/kg body weight/day of the inhibitor can be administered to a patient receiving these compositions.

[00132] It should also be understood that a specific dosage and treatment regimen for any particular patient will depend upon a variety of factors, including age, body weight, general health, sex, diet, time of administration, rate of excretion, drug combination, the judgment of the treating physician, and the severity of the particular disease being treated. The amount of a provided compound in the composition will also depend upon the particular compound in the composition.

[00133]Compounds or compositions described herein may be administered using any amount and any route of administration effective for treating or lessening the severity of the disorders or diseases as contemplated herein. The exact amount required will vary from subject to subject, depending on the species, age, and general condition of the subject, the severity of the infection, the particular agent, its mode of administration, and the like. Provided compounds are preferably formulated in unit dosage form for ease of administration and uniformity of dosage. The expression "unit dosage form" as used herein refers to a physically discrete unit of agent appropriate for the patient to be treated. It will be understood, however, that the total daily usage of the compounds and compositions of the present disclosure will be decided by the attending physician within the scope of sound medical judgment. The specific effective dose level for any particular patient or organism will depend upon a variety of factors including the disorder being treated and the severity of the disorder; the activity of the specific compound employed; the specific composition employed; the age, body weight, general health, sex and diet of the patient; the time of administration, route of administration, and rate of excretion of the specific compound employed; the duration of the treatment; drugs used in combination or coincidental with the specific compound employed, and like factors well known in the medical arts. [00134] Pharmaceutically acceptable compositions of this disclosure can be administered to humans and other animals orally, rectally, parenterally, intracisternally, intravaginally, intraperitoneally, topically (as by powders, ointments, or drops), buccally, as an oral or nasal spray, or the like, depending on the severity of the infection being treated. In certain embodiments, provided compounds may be administered orally or parenterally at dosage levels of about 0.01 mg/kg to about 50 mg/kg and preferably from about 1 mg/kg to about 25 mg/kg, of subject body weight per day, one or more times a day, to obtain the desired therapeutic effect. Combinations

[00135]Depending upon the particular condition, or disease, to be treated, additional therapeutic agents that are normally administered to treat that condition may also be present in the compositions of this disclosure or administered separately as a part of a dosage regimen. As used herein, additional therapeutic agents that are normally administered to treat a particular disease, or condition, are known as "appropriate for the disease, or condition, being treated."

[00136] In some embodiments, the composition of a compound or compounds described herein can be in combination with an additional therapeutic agent. [00137] It will be understood, however, that the total daily usage of the compounds and compositions of the present description will be decided by the attending physician within the scope of sound medical judgment. The specific inhibitory dose for any particular patient will depend upon a variety of factors including the disorder being treated and the severity of the disorder; the activity of the specific compound employed; the specific composition employed; the age, body weight, general health, sex and diet of the patient; the time of administration, route of administration, and rate of excretion of the specific compound employed; the duration of the treatment; drugs used in combination or coincidental with the specific compound employed; and like factors well known in the medical arts.

[00138]The total daily dose of the compounds of the present description administered to a subject in single or in divided doses can be in amounts, for example, from 0.01 to 50 mg/kg body weight or more usually from 0.1 to 25 mg/kg body weight. Single dose compositions may contain such amounts or submultiples thereof to make up the daily dose. In one embodiment, treatment regimens according to the present description comprise administration to a patient in need of such treatment from about 10 mg to about 1000 mg of the compound(s) of the present description per day in single or multiple doses.

[00139]As used herein, the term "combination," "combined," and related terms refers to the simultaneous or sequential administration of therapeutic agents in accordance with the present description. For example, a provided compound may be administered with another therapeutic agent simultaneously or sequentially in separate unit dosage forms or together in a single unit dosage form. Accordingly, an embodiment of the present description provides a single unit dosage form comprising a provided compound, an additional therapeutic agent, and a pharmaceutically acceptable carrier, adjuvant, or vehicle for use in the methods of the present description. [00140]The amount of both, a provided compound and additional therapeutic agent (in those compositions which comprise an additional therapeutic agent as described above) that may be combined with the carrier materials to produce a single dosage form will vary depending upon the host treated and the particular mode of administration. Preferably, compositions should be formulated such that a dosage of between 0.01 - 100 mg/kg body weight/day of a provided compound can be administered.

[00141 ]ln those compositions which comprise an additional therapeutic agent, that additional therapeutic agent and the provided compound may act synergistically. Therefore, the amount of additional therapeutic agent in such compositions will be less than that required in a monotherapy utilizing only that therapeutic agent. In such compositions a dosage of between 0.01 - 1 ,000 g/kg body weight/day of the additional therapeutic agent can be administered.

[00142]The amount of additional therapeutic agent present in the compositions of this disclosure will be no more than the amount that would normally be administered in a composition comprising that therapeutic agent as the only active agent. Preferably the amount of additional therapeutic agent in the presently disclosed compositions will range from about 50% to 100% of the amount normally present in a composition comprising that agent as the only therapeutically active agent.

[00143] Provided compounds, or pharmaceutical compositions thereof, may also be incorporated into compositions for coating an implantable medical device, such as prostheses, artificial valves, vascular grafts, stents and catheters. Vascular stents, for example, have been used to overcome restenosis (re-narrowing of the vessel wall after injury). However, patients using stents or other implantable devices risk clot formation or platelet activation. These unwanted effects may be prevented or mitigated by pre- coating the device with a pharmaceutically acceptable composition comprising a provided compound. Implantable devices coated with a compound of the present description are another embodiment of the present description.

[00144] In another aspect, the present description provides a method of method of synthesizing a compound of any of the formulae herein.

[00219] C (1 g, 0.71 mM) in AcOH ( 10 mL) was treated with Ac ₂ 0 (0.33 mL, 3.46 mM), the mixture stirred for 15 minutes then diluted with methanol (5 mL) and treated with Pd 10%/C ( 100 mg) under an atmosphere of H2 (balloon) over night. Nitrogen was bubbled in the mixture which was then filtered on celite using methanol, the solvent was evaporated. The residue was purified using a silica gel column on the combiflash 0% to 80% methanol/ CH2CI2, methanol containing 5 % HCOOH, giving 65 mg of the titled compound of Ex.5. Low resolution Mass Spectroscopy (+): 1371 .9 [M+1 ].

Example 6:HCT assay

The compounds were evaluated in a proliferation assay using HCT-1 16 cells using an xCELLigence system. The results are shown in Table 2 below. Briefly, the xCELLigence system monitors cellular events in real time by measuring electrical impedance across interdigitated micro-electrodes integrated on the bottom of tissue culture E-Plates. The impedance measurement provides quantitative information about the biological status of the cells, including cell number, viability, and morphology. Real-time proliferation assays were then to determine the IC50 values. All proliferation assays start 24 hours after the transfection.

Example 7: GalN/LPS Fulminant Liver Injury Model: An Antiinflammatory, Anti-TNFoc, Hepatoprotection model.

A Galactosamine/ Liposaccharide (GalN/LPS) fulminant liver injury model may be used to evaluate the anti-inflammatory, anti-TNFa and hepatoprotective properties of the compound of the description.

Mice were maintained under 12 h light/dark cycles with unlimited access to food and water. Study was performed in 6- to 14-week old male mice. C57BL/6 mice were used. Mice are first injected with pentamidine or Example 2 compound (IP injection). 30 minutes later, liver injury is induced by intraperitoneal injections of 100 μg/kg of LPS (E. coli 01 1 1 :B4) and 700 mg/kg of GaIN (Sigma) dissolved in phosphate-buffered saline (PBS).

Study a

The tested compounds were be dosed IP 30-minutes prior to the co-treatment with galactosamine (GaIN) and endotoxin (Lipopolysaccharide) LPS. Mice were either sacrificed at 6.5 hours after GalN/LPS for ALT analysis, or kept for longer periods to evaluate survival. The analysis of alanine transaminase (ALT) serum levels and histological observations allow the evaluation of the hepatoprotective, anti-TNF-a, anti-inflammatory and/or anti-fibrotic activity. Survival was evaluated at two time points, i.e. 8 and 23 hours. In controls group receiving PBS prior to the GalN/LPS liver injury, no mice survived 8 hours. In groups treated with control pentamidine at doses of 25 and 40 mg/kg, only the 40 mg/kg (67 group benefited from hepatoprotective properties of pentamidine at 8 hours, but none survived 23 hours. In the case of trihexamidine isethionate, all mice survived more than 23 hours with 10 mg/kg (8.6 doses. These results strongly support the hepatoprotective activity of triamidines (Figures 1 and 2).

Study b

All doses were administered IP to six mice (n=6), 30 minutes prior to the injection of the GaIN and LPS, when applicable to the group. Blood samples were collected exactly 6 hours post GalN/LPS injections, or 6.5 hours after vehicle injections.

The tested compounds were dosed IP 30 minutes prior to the co-treatment with galactosamine (GaIN) and endotoxin (Lipopolysaccharide) LPS. Mice were sacrificed at 6 hours after GalN/LPS for ALT analysis. The analysis of alanine transaminase (ALT) serum levels allows the evaluation of the hepatoprotective, anti-TNF-a, anti-inflammatory and/or anti-fibrotic activity.

Results indicate that Compounds 2, 4 and 5 (C2, C4, C5) are hepatoprotective in the model, as shown by low ALT activity levels following the injection of GalN/LPS. See Figure 3. Animals treated with pentamidine at the dose of 50 mg/kg (84 benefited from hepatoprotective properties of pentamidine (positive control, Penta-50mpk). Significant hepatoprotection was also provided by lower doses: 10 mg/kg (4.3 and 8.6 for C2, 5 and 10 mg/kg (3.3 and 6.6 for C4 and 5 mg/kg (6.3 mole/kg) for C5. These results strongly support the hepatoprotective activity of the tested compounds (Figure 3).

The tested compounds were dosed IP 30 minutes prior to the co-treatment with galactosamine (GaIN) and endotoxin (Lipopolysaccharide) LPS. Mice were sacrificed at 6 hours after GalN/LPS for ALT analysis. The analysis of alanine transaminase (ALT) serum levels allows the evaluation of the hepatoprotective, anti-TNF-a, anti-inflammatory and/or anti-fibrotic activity.

Results indicate that Compound 4 (C4) provides a dose-dependent hepatoprotection in the model, as shown by low ALT activity levels following the injection of GalN/LPS. See Figure 4. Animals treated with pentamidine at the dose of 50 mg/kg (84 benefited from hepatoprotective properties of pentamidine (positive control, Penta-50mpk). Significant hepatoprotection was also provided by C4 at 0.625 mg/kg (0.8 mole/kg), 1 .25 mg/kg (1 .6 mole/kg) and 2.5 mg/kg (3.2 mole/kg) for C5. These results strongly support the hepatoprotective activity of the tested compounds (Figure 4). Example 8

DSS-lnduced Acute Colitis in Mice (Compound 2 and Compound 4)

Study summary

Formulation Dextran Sulfate Sodium 2.5% stocks were prepared by adding tap water in the pre-weighed powder. DSS solutions will be changed every 3 days for all groups, i.e. on Day 1 (D1 ) and Day 4 (D4).

Formulations for intraperitoneal administration: - Vehicle: sterile double distilled water (DDW)

- For Pentamidine (Penta) and Compounds 2 and 4, the compounds were dissolved in DDW and dosed at 2 mL/kg to yield the indicated doses.

In-vivo study Male C57BL/6 ELITE mice of ~7-8 weeks old were used. After 5-day acclimatization period in animal facility, all mice were weighed and given tap water containing 2.5 % DSS on Day 1 , treatment also starts on Day 1 .

Table 1 : Groups

Husbandry

The animal room environment is controlled (temperature 22 ± 0.2°C; relative humidity 55 ± 25%; 12 hours light/dark cycle, and 12 air changes per hour). A standard certified commercial rodent chow is provided to the animals ad libitum. Procedures involving the care and use of animals in this study will be reviewed and approved by the Institutional Animal Care and Use Committee (IACUC) prior to conduct.

Treatment and daily observations On the morning of Day 1 (D1 ), the drinking water will be replaced by 2.5% DSS- containing tap water.

Animals were dosed from D1 to D6, once daily by IP injection (2 mL/kg).

Animals were terminated on D7. The Disease Activity Index (DAI) scale is based on the evaluation of different parameters characterizing experimental colitis induction and progression. Body weight, presence of gross blood in the feces and stool consistency will be recorded daily.

Disease Accumulated Index is determined by scoring changes in:

• Weight loss : 0 = none; 1 = 1 to 5%; 2 = 5 to 10%; 3 =_10 to 20%; 4 = >20% · Stool consistency : 0 = normal; 2 = loose; 4 = diarrhea

• Rectal bleeding : 0 = normal; 2 = occult bleeding; 4 = gross bleeding Moreover, animals will be monitored for pain level and hydration. If they seem in distress or obtain a final Disease Activity Index of 12 points (per mouse), they will be considered reaching clinical end point for euthanasia.

Termination On Day 7, mice will be weighed and disease scores evaluated, and then euthanized by CO2 inhalation.

Conclusion

Compounds 2 and 4 have reduced the disease activity index in the DSS-induce acute colitis model, demonstrating their potential in treating Gl disorders related to inflammatory conditions. The results are shown in Figure 5.
