ARYL-PIPERIDINE DERIVATIVES

Description

[0001] The present invention relates to aryl-piperidine derivatives of formula I useful for the treatment and/or prevention of an autoimmune disease, a mast-cell mediated allergy, a rejection of an allotransplant or a xenotransplant of an organ or a tissue, a lymphoma or a T-cell leukaemia, through the inhibition of T cells. Moreover, the invention relates to a process for the preparation thereof, and to pharmaceutical compositions that comprise these compounds.

STATE OF THE ART

[0002] T cells are directly involved in the pathogenesis of autoimmune diseases (ADs), allergies, and diseases associated with abnormal performance of the immune system. T cells require three signals for their activation to take place, signal 1, derived from the T cell antigen receptors (TCR); signal 2, derived from co-stimulatory receptors, e.g. CD28 upon binding to its ligands on the antigen-presenting cells (APC); and signal 3, a signal derived from cytokine receptors responsible for T cells proliferation and differentiation. The mechanism of action of the currently-used immunosuppressant drugs is based on the inhibition of the activation of signals 2 or 3, and include drugs such as belatacept and basiliximab, reslizumab, etc., respectively. The drawback of acting on signals 2 and 3 is that these signals are not limited to the activation of T cells. This means that currently-used immunosuppressant drugs do not inhibit T cells in a specific manner, and therefore, present high toxicity. In contrast the TCR signal is limited to T cells. The T cell recognizes antigen peptides associated to the major histocompatibility complex, also known as MHC, (pMHC) through TCR. The TCR is formed by 6 subunits, 2 of which, namely, TCRa and TCRP, are responsible for the recognition of the antigen peptide associated MHC; whereas the other 4 subunits (i.e. CD3y, CD35, CD3s and Οϋ3ζ) are responsible for the transmission of signals to the T cell cytoplasm. One of the initial processes that takes place following ligation of the TCR by the MHC is activation of the src-family tyrosine kinases Lck and Fyn, which phosphorylate the tyrosines in the immunoreceptor tyrosine-based activation motifs (ITAM) of the CD3 subunits. These, in turn, become anchor sites for the Syk-family tyrosine kinases (ZAP70 and Syk). In addition, the TCR undergoes a conformational change that results in the direct recruitment of the Nek adaptor to a proline-rich sequence (PRS) of the CD3s subunit. This TCR-Nck interaction takes place between the PRS portion of CD3s, and the amino-terminal SH3.1 domain of Nek. Therefore, Nek is necessary for the activation of T lymphocytes in response to stimulation of the TCR. The compounds of the present invention surprisingly act blocking the TCR-Nck interaction, and consequently the abnormal proliferation of T cells.

[0003] Autoimmune diseases and diseases associated with abnormal performance of the immune system, in general, such as mast-cells mediated allergies, lymphomas and rejection of allotransplants, are a diverse group of diseases whereby the adaptive immune system (in particular, through T cells) attacks the body's antigens. These diseases are extremely relevant, both from the social and the economic standpoint. The latest statistics indicate that between 3 and 5% of the population suffers from autoimmune diseases. This incidence, and the chronic nature of these diseases, represent a high cost for health systems.

[0004] State of the art document WO2005046685A1 discloses also aryl-piperidines derivatives, as well as their medical use. In particular, the therein disclosed compounds are used in the treatment of diseases mediated by the inhibition of 11-β-hydroxysteroid dehydrogenase type 1 enzyme (1 lpHSDl), hence, metabolic syndromes, such as diabetes type II and obesity.

[0005] Therefore, there is a need in the field to provide new compounds capable of blocking the TCR-Nck interaction, and consequently capable of inhibiting T cells abnormal activation/proliferation.

[0050] In another embodiment, the invention relates to the compounds of formula I that produce inhibition of T cells proliferation in a T cells inhibition assay such as the one described in the activity example.

[0051] The compounds of the present invention contain one or more basic nitrogens and, therefore, may form salts by reacting with acids, both organic and inorganic. Examples of said salts include without limitation: salts of inorganic acids, such as hydrochloric acid, hydrobromic acid, hydriodic acid, nitric acid, perchloric acid, sulfuric acid or phosphoric acid; and salts of organic acids, such as methanesulfonic acid, trifluoromethanesulfonic acid, ethanesulfonic acid, benzenesulfonic acid, p-toluenesulfonic acid, fumaric acid, oxalic acid, acetic acid, maleic acid, ascorbic acid, citric acid, lactic acid, tartaric acid, malonic acid, glycolic acid, succinic acid and propionic acid, amongst others. Some compounds of the present invention may contain one or more acidic protons and, therefore, may also form salts by reacting with bases.

[0052] There are no limitations as to the types of salts that may be used, provided that they are pharmaceutically acceptable to be used for therapeutic purposes. Pharmaceutically acceptable salts are understood to mean those salts which, according to medical criteria, are adequate to be used in contact with human beings' or other mammals' tissues without causing undue toxicity, irritation, allergic responses or similar effects. Pharmaceutically acceptable salts are widely known to a person skilled in the art.

[0053] The salts of a compound of the invention may be obtained during the final isolation and purification of the compounds of the invention or be prepared by treating a compound of the invention with a sufficient quantity of the desired acid or base to produce the salt in a conventional manner. The salts of compounds of the invention may, in turn, be converted into other salts by means of ion-exchange using an ion-exchange resin.

[0054] The compounds of the invention and the salts thereof may differ in terms of certain physical properties, but, for purposes of the invention, are equivalent. All the salts of compounds of the invention are included within the scope of the invention.

[0055] The compounds of the present invention may form complexes with solvents with which they are made to react or from which they are precipitated or crystallised. These complexes are known as solvates. As used herein, the term "solvate" refers to a complex of variable stoichiometry formed by a solute (a compound of the invention or a salt thereof) and a solvent. Examples of solvents include pharmaceutically acceptable solvents such as, without limitation, water, ethanol and similar ones. A complex formed by water is known as a hydrate. Solvates of the compounds of the invention (or the salts thereof), including hydrates, are included within the scope of the invention.

[0056] The compounds of the invention may exist in different physical forms, i.e. in amorphous form and in crystalline forms. Moreover, the compounds of the present invention may be capable of crystallising in more than one form, a characteristic known as polymorphism. Polymorphs may differ in some physical properties widely known to persons skilled in the art, such as, for example, X-ray diffractograms, melting points or solubility. All the physical forms of the compounds of the invention, including all the polymorphic forms thereof ("polymorphs"), are included within the scope of the present invention.

[0057] Some compounds of the present invention may exist in the form of several diastereoisomers and/or several optical isomers. Diastereoisomers may be separated by means of conventional techniques, such as fractional chromatography or crystallisation. Optical isomers may be resolved by means of conventional optical resolution techniques, to produce optically pure isomers. This resolution may be performed on chiral synthesis intermediate compounds or on the compounds of the invention. The optically pure isomers may also be individually obtained using enantiospecific syntheses. The present invention includes both individual isomers and mixtures thereof (for example, racemic mixtures or mixtures of diastereoisomers), whether obtained by means of synthesis or by physical mixing. The compounds of formula I wherein X is a ketone have two enantiomers. Similarly, the compounds of formula I wherein X is an -OH have 2 diasteroisomers. We described the detailed synthesis of such compounds, each of them representing a racemic mixture of 2 enantiomers, i.e. the 2 diasteroisomers VII-1-01 and VII-1- 02, or VII-2-01 and VII-2-02.

[0058] The present invention also relates to a pharmaceutical composition that comprises a compound of the invention (or a pharmaceutically acceptable salt or solvate thereof) and one or more pharmaceutically acceptable excipients. The excipients must be "acceptable" in the sense of being compatible with the remaining ingredients of the composition and not be harmful for those taking said composition.

[0059] The compounds of the present invention may be administered in the form of any pharmaceutical formulation, the nature whereof, as is well known, will be dependent on the nature of the active principle and its administration route. In principle, any administration route may be used, for example, oral, parenteral, nasal, ocular, rectal, and topical. [0060] Solid compositions for oral administration include tablets, granules and capsules.

In any case, the manufacturing method will be based on simple mixing, dry granulation or wet granulation of the active principle with excipients. These excipients may be, for example, diluents such as lactose, microcrystalline cellulose, mannitol or calcium hydrogen phosphate; binding agents such as, for example, starch, gelatine or polyvinylpyrrolidone; disaggregating agents such as sodium carboxymethyl starch or sodium croscarmellose; and lubricating agents such as, for example, magnesium stearate, stearic acid or talc. The tablets may further be coated with adequate excipients by means of known techniques, in order to delay the disaggregation and absorption thereof in the gastrointestinal tract, and thus achieve a sustained action over a longer period of time, or simply improve their organoleptic properties or their stability. The active principle may also be incorporated by coating inert pellets using natural or synthetic filmogenic polymers. It is also possible to manufacture soft gelatine capsules, wherein the active principle is mixed with water or with an oily medium, such as, for example, coconut oil, liquid paraffin or olive oil.

[0061] Powders and granules may be obtained in order to prepare oral 10 suspensions by adding water, mixing the active principle with dispersing or wetting agents, suspending agents and preservatives. Other excipients may also be added, for example, sweetening, flavouring and colouring agents.

[0062] Liquid forms for oral administration may include emulsions, solutions, suspensions, syrups and elixirs that contain commonly used inert diluents, such as distilled water, ethanol, sorbitol, glycerol, polyethylene glycols (macrogols) and propylene glycol. Said compositions may also contain adjuvants, such as wetting, suspending, sweetening and flavouring agents, preservatives and pH regulators.

[0063] According the present invention, injectable preparations, for parenteral administration, comprise sterile solutions, suspensions or emulsions, in an aqueous or non-aqueous solvent, such as propylene glycol, polyethylene glycol or vegetable oils. These compositions may also contain adjuvants, such as wetting, emulsifying and dispersing agents, and preservatives. They may be sterilised by means of any commonly known method or prepared as sterile solid compositions that are subsequently dissolved in water or any other sterile injectable medium immediately prior to use. It is also possible to start from sterile raw materials and keep them under these conditions during the entire manufacturing process. [0064] For rectal administration, the active principle may be preferably formulated as suppositories on oily bases, such as, for example, vegetable oils or semi-synthetic solid glycerides, or on hydrophilic bases, such as polyethylene glycols (macrogols).

[0065] The compounds of the invention may also be formulated for topical application, for the treatment of pathologies that affect areas or organs that are accessible by said route, such as the eyes, the skin and the intestinal tract. These formulations include creams, lotions, gels, powders, solutions and patches wherein the compound is dispersed or dissolved in adequate excipients.

[0066] For nasal administration or inhalation, the compound may be formulated in the form of an aerosol, wherefrom it is conveniently released using adequate propellants.

[0067] The appropriate dosage as well as the dosing frequency of the compounds of the invention, or the salts thereof, within the pharmaceutical composition will depend on the nature of the disease to be treated or prevented, the severity and the course of the disease, the subject's age, gender, general condition and weight, whether the composition is administered for preventive or therapeutic purposes, among other factors. The amount of the compound of the invention, or salt thereof, or the pharmaceutical composition is administered to the subject at one time or over a series of treatments. Depending on the type and severity of the disease, an appropriate dosage level will generally be about 0.01 to 1,000 mg per kg patient body weight per day which can be administered in single or multiple doses. Preferably, the dosage level will be about 0.1 to about 500 mg/kg per day; more preferably about 0.25 to about 250 mg/kg per day; more preferably about 0.5 to about 100 mg/kg per day. A suitable dosage level may be about 0.01 to 250 mg/kg per day, about 0.05 to 100 mg/kg per day, or about 0.1 to 50 mg/kg per day. For oral administration, the composition is preferably provided in the form of tablets, containing about 1.0 to about 1,000 mg of active compound, particularly at least about 1.0, at least about 5.0, at least about 10.0, at least about 15.0, at least about 20.0, at least about 25.0, at least about 50.0, at least about 75.0, at least about 100.0, at least about 150.0, at least about 200.0, at least about 250.0, at least about 300.0, at least about 400.0, at least about 500.0, at least about 600.0, at least about 750.0, at least about 800.0, at least about 900.0 or at least about 1000.0 mg. The compound, salt thereof, or pharmaceutical composition may be administered on a regime of 1 to 4 times per day, preferably one or twice per day. [0068] The compounds of this invention may be prepared by means of the processes described below. In order to facilitate the description of the processes, we have used specific examples, which do not in any way limit the scope of the present invention.

[0069] Throughout the description and claims, the word "comprises" and variants thereof are not intended to exclude other technical features, additives, components or steps. Additional objects, advantages and features of the invention will become apparent to those skilled in the art upon examination of the description or may be learned by practice of the invention. The following examples are provided for illustrative purposes, and are not intended to limit the scope of the present invention. Furthermore, the present invention covers all possible combinations of particular embodiments.

[00197] According to another embodiment, the invention provides a composition comprising a compound of this invention or a pharmaceutically acceptable salt thereof, and a pharmaceutically acceptable carrier, adjuvant, or vehicle. The amount of compound in compositions of this invention is such that is effective to measurably modulate the interaction between TCR and Nek, in a biological sample or in a patient. In certain embodiments, the amount of compound in compositions of this invention is such that is effective to measurably modulate the interaction between TCR and Nek in a biological sample or in a patient. In certain embodiments, a composition of this invention is formulated for administration to a patient in need of such composition. In some embodiments, a composition of this invention is formulated for oral administration to a patient. [00198] The term "patient," as used herein, means an animal, preferably a mammal, and most preferably a human.

[00199] 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 invention 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.

[00200] Compositions of the present invention 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. Preferably, the compositions are administered orally, intraperitoneally or intravenously. Sterile injectable forms of the compositions of this invention may be aqueous or oleaginous suspension. These suspensions may be formulated according to techniques known in the art using suitable dispersing or wetting agents and suspending agents. The sterile injectable preparation may also be a sterile injectable solution or suspension in a non-toxic 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 and isotonic sodium chloride solution. In addition, sterile, fixed oils are conventionally employed as a solvent or suspending medium.

[00201] For this purpose, any bland fixed oil may be employed including synthetic mono- or di-glycerides. Fatty acids, such as oleic acid and its glyceride derivatives are useful in the preparation of injectables, as are natural pharmaceutically-acceptable oils, such as olive oil or castor oil, especially in their polyoxy ethyl ated versions. These oil solutions or suspensions may also contain a long-chain alcohol diluent or dispersant, such as carboxymethyl cellulose or similar dispersing agents that are commonly used in the formulation of pharmaceutically acceptable dosage forms including emulsions and suspensions. Other commonly used surfactants, such as Tweens, Spans and other emulsifying agents or bioavailability enhancers which are commonly used in the manufacture of pharmaceutically acceptable solid, liquid, or other dosage forms may also be used for the purposes of formulation.

[00202] Pharmaceutically acceptable compositions of this invention may be orally administered in any orally acceptable dosage form including, but not limited to, capsules, tablets, aqueous suspensions or solutions. In the case of tablets for oral use, carriers commonly used include lactose and corn starch. Lubricating agents, such as magnesium stearate, are also typically added. For oral administration in a capsule form, useful diluents include lactose and dried cornstarch. When aqueous suspensions are required for oral use, the active ingredient is combined with emulsifying and suspending agents. If desired, certain sweetening, flavoring or coloring agents may also be added.

[00203] Alternatively, pharmaceutically acceptable compositions of this invention may be administered in the form of suppositories for rectal administration. These can be prepared by mixing the agent with a suitable non-irritating excipient that is solid at room temperature but liquid at rectal temperature and therefore will melt in the rectum to release the drug. Such materials include cocoa butter, beeswax and polyethylene glycols.

[00204] Pharmaceutically acceptable compositions of this invention may also be administered topically, especially when the target of treatment includes areas or organs readily accessible by topical application, including diseases of the eye, the skin, or the lower intestinal tract. Suitable topical formulations are readily prepared for each of these areas or organs.

[00205] Topical application for the lower intestinal tract can be effected in a rectal suppository formulation (see supra) or in a suitable enema formulation. Topically-transdermal patches may also be used.

[00206] For topical applications, provided pharmaceutically acceptable compositions may be formulated in a suitable ointment containing the active component suspended or dissolved in one or more carriers. Carriers for topical administration of compounds of this invention include, but are not limited to, mineral oil, liquid petrolatum, white petrolatum, propylene glycol, polyoxyethylene, polyoxypropylene compound, emulsifying wax and water. Alternatively, provided pharmaceutically acceptable compositions can be formulated in a suitable lotion or cream containing the active components suspended or dissolved in one or more pharmaceutically acceptable carriers. Suitable carriers include, but are not limited to, mineral oil, sorbitan monostearate, polysorbate 60, cetyl esters wax, cetearyl alcohol, 2-octyldodecanol, benzyl alcohol and water.

[00207] For ophthalmic use, provided pharmaceutically acceptable compositions may be formulated as micronized suspensions in isotonic, pH adjusted sterile saline, or, preferably, as solutions in isotonic, pH adjusted sterile saline, either with or without a preservative such as benzylalkonium chloride. Alternatively, for ophthalmic uses, the pharmaceutically acceptable compositions may be formulated in an ointment such as petrolatum.

[00208] Pharmaceutically acceptable compositions of this invention may also be administered by nasal aerosol or inhalation. Such compositions are prepared according to techniques well-known in the art of pharmaceutical formulation and may be prepared as solutions in saline, employing benzyl alcohol or other suitable preservatives, absorption promoters to enhance bioavailability, fluorocarbons, and/or other conventional solubilizing or dispersing agents.

[00209] Most preferably, pharmaceutically acceptable compositions of this invention are formulated for oral administration. Such formulations may be administered with or without food. In some embodiments, pharmaceutically acceptable compositions of this invention are administered without food. In other embodiments, pharmaceutically acceptable compositions of this invention are administered with food.

[00210] The amount of compounds of the present invention that may be combined with the carrier materials to produce a composition in a single dosage form will vary depending upon the host treated, the particular mode of administration. Preferably, provided compositions should be formulated so 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.

[00211] It should also be understood that a specific dosage and treatment regimen for any particular patient will depend upon a variety of factors, including the activity of the specific compound employed, the age, body weight, general health, sex, diet, time of administration, rate of excretion, drug combination, and the judgment of the treating physician and the severity of the particular disease being treated. The amount of a compound of the present invention in the composition will also depend upon the particular compound in the composition. [00212] Pharmaceutically acceptable compositions of this invention can be administered to humans and other animals orally, rectally, parenterally, intracisternally, intravaginally, intraperitoneally, topically (as by powders, ointments, or drops), bucally, as an oral or nasal spray, or the like, depending on the severity of the infection being treated. In certain embodiments, the compounds of the invention 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.

[00213] 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.

[00214] 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.

[00215] 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. [00216] In order to prolong the effect of a compound of the present invention, 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. 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.

[00217] Compositions for rectal or vaginal administration are preferably suppositories which can be prepared by mixing the compounds of this invention 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.

[00218] 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. [00219] 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 polethylene glycols and the like.

[00220] The active 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.

[00221] Dosage forms for topical or transdermal administration of a compound of this invention 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 this invention. Additionally, the present invention 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.

[00222] The term "biological sample", as used herein, includes, without limitation, cell cultures or extracts thereof; biopsied material obtained from a mammal or extracts thereof; and blood, saliva, urine, feces, semen, tears, or other body fluids or extracts thereof.

Autoimmune and Inflammatory Disorders

[00264] As used herein, "autoimmune and inflammatory disorder" refers to those diseases, illnesses, or conditions engendered when the host's systems are attacked by the host's own immune system. The targets of autoimmune interaction can range anywhere from the cellular level {e.g., myelin basic protein in multiple sclerosis, or the thyrotropin receptor in Graves' disease) to organ specific effects in rheumatoid arthritis or Crohn's disease to system wide effects as seen in systemic lupus erythematosus. Some of the events that have been postulated in the causation of autoimmune diseases have included cytokine over expression, for example TNF-a, IL-2, or JL-2 receptor in inflammatory bowel disease, or under expression (IL-10 under expression in Type 1 diabetes), to defects in allele expression (HLA Class I B27 in ankylosing spondylitis), to altered expression of apoptosis proteins (under expression of Fas in autoimmune lymphoproliferative syndrome type I (ALPS 1).

Combinations

[00272] A compound of the current invention can be administered alone or in combination with one or more other therapeutic compounds, possible combination therapy taking the form of fixed combinations or the administration of a compound of the invention and one or more other therapeutic compounds being staggered or given independently of one another, or the combined administration of fixed combinations and one or more other therapeutic compounds. 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."

[00273] Those additional agents may be administered separately from an inventive compound-containing composition, as part of a multiple dosage regimen. Alternatively, those agents may be part of a single dosage form, mixed together with a compound of this invention in a single composition. If administered as part of a multiple dosage regime, the two active agents may be submitted simultaneously, sequentially or within a period of time from one another normally within five hours from one another.

[00274] As used herein, the term "combination," "combined," and related terms refers to the simultaneous or sequential administration of therapeutic agents in accordance with this invention. For example, a compound of the present invention may be administered with another therapeutic agent simultaneously or sequentially in separate unit dosage forms or together in a single unit dosage form. Accordingly, the present invention provides a single unit dosage form comprising a compound of the current invention, an additional therapeutic agent, and a pharmaceutically acceptable carrier, adjuvant, or vehicle.

[00275] The amount of both an inventive 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 of this invention should be formulated so that a dosage of between 0.01 - 100 mg/kg body weight/day of an inventive compound can be administered.

[00276] In those compositions which comprise an additional therapeutic agent, that additional therapeutic agent and the compound of this invention 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 μg/kg body weight/day of the additional therapeutic agent can be administered.

[00277] The amount of additional therapeutic agent present in the compositions of this invention 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.

[00278] In one embodiment, the present invention provides a composition comprising a compound of formula I and one or more additional therapeutic agents. The therapeutic agent may be administered together with a compound of formula I, or may be administered prior to or following administration of a compound of formula I.

1-01, VII-1-02, 1-1, IV-10, V-2, V-4, V-3, V-5, V-6 and V-9, on the capacity of the TCR to induce T cells proliferation was evaluated on primary T cells obtained from the blood of healthy human donors (PBMCs; peripheral blood mononuclear cells). The volunteers' PBMCs were isolated by means of density gradient centnfugation of venous blood using Ficoll-Paque Plus. The purified cells (NWT; Nylon Wood T cells) were labelled with carboxyfluorescein succinimidyl ester (CFSE) in order to analyse the cell division capacity. The labelled cells were pre-incubated for 1 hour in the absence or in the presence of the compounds at a concentration of 0.1 and 1.0 nM. Subsequently, the TCR/CD3 complex was stimulated using immobilised OKT3 (10 μg/ml) on flat- bottom P96 plates from Costar. The cells were cultured in triplicate at a density of 0.2 x 10 ⁵ in 200 μΐ of full medium, and the proliferation was evaluated by means of flow cytometry after 5-7 days, by quantifying the fluorescence of the CFSE. As the cells divide, they dilute the amount of labelling incorporated into the daughter cells, which gives an idea of the degree of cell proliferation. The inhibitory capacity of the compounds tested at a concentration of 0.1 and 1.0 nM, is shown in Fig. 1 and 2, respectively.

Example 3. CYP Inhibition

[00354] The effect of compounds IV-6, IV-7, and V-4 on Cytochromes P450 (CYP) inhibition was evaluated.

[00355] For each isozyme, microsomes-buffer-substrate mixture (MBS mix) is prepared by premixing appropriate volumes of buffer, microsomes and substrate. MBS mixture (179 μΐ.) is transferred to a 96-well reaction plate. An aliquot (1 μί) is spiked from conesponding wells of Test Item stock solution plate to reaction plate. The reaction plate is pre-incubated for 5 minutes at 37 °C. Reaction is initiated by the addition of 20 μΙ_, of NADPH solution. Each experiment is performed in duplicate. Reaction plate is incubated for predetermined time at 37 °C and quenched using either 200 μΐ, of acetonitrile (for CYP2C9, CYP2D6, CYP2C19 and CYP3A4) or 200 μΐ, of a mixture of 70:30 1% formic acid: acetonitrile (for CYP1A2). The protein concentration, incubation time, substrate concentrations and metabolite monitored for each CYP is given in the table below:

0.15 6-β -hydroxy testosterone

[00356] Certain CYP inhibition data is shown in Table 5, below. Class A: IC50 < 5 uM;

Class B: 5 uM < IC50 < 20 uM; Class C: 20 uM < IC50 < 50 uM; Class D: IC50 > 50 uM.

Example 4. Microsomal Stability

[00357] The microsomal stability of compounds IV-6, IV-7, and V-4 was evaluated.

[00358] Intrinsic clearance studies are performed individually with mouse, rat and human liver microsomes at 0.5 mg/mL protein concentration. Briefly, for protein concentration 0.5 mg/mL assay, liver microsomal protein (12.5 uL), NAPDH (50 uL) and phosphate buffer (435 uL) are co-incubated (pre-incubation) in a 96-well deep well plate in an orbital incubator (10 min, 37 °C). Reactions are initiated by the addition of 2.5 uL of test item working stock solution (100 uM). Aliquots (50 uL) are withdrawn from the reaction tube at 0, 5, 10, 20 and 30 minutes and the reaction is immediately terminated by transferring to a 96 deep well plate containing 50 uL of acetonitrile. Verapamil is used as a positive control in mouse, rat and human liver microsomes. To the quenched samples internal standard is added and vortex mixed followed by centrifugation at 4000 rpm for 10 minutes and an aliquot of supernatant is taken for LC -MS/MS analysis. Samples are analyzed by a suitable fit-for-purpose multiple reaction monitoring method developed on LC- MS/MS using and API 4000 mass spectrometer to estimate the area ratio (analyte peak area/internal standard peak area).

[00359] Certain microsomal stability data is shown in Table 6, below. Class A: Tl/2 > 30 minutes; Class B: 10 minutes < Tl/2 < 30 minutes; Class C: Tl/2 < 10 minutes.

Example 5. hERG Inhibition

[00360] The effect of compounds IV-6, IV-7, and V-4 on hERG inhibition was evaluated.

[00361] HEK cells stably transfected with the hERG clone are maintained at 37±2 °C in a 5% C02 incubator. The cells are initially revived and grown in DMEM/F 12 + GlutaMAX-I medium supplemented with 9% fetal bovine serum (FBS) and antibiotics (Penicillin 100 R7/mL Streptomycin 100 μg/mL) (complete medium). Furthermore, the cells are continuously maintained and passaged in complete media in addition to the appropriate concentration of selection antibiotic (Geneticin (G418) 200 μg/mL) (Selection media). The cells are sub cultured every 2-3 days and medium is changed with complete medium at least a day before the experiment.

[00362] The cells are harvested on the day of experiment, dislodged and suspended in sterile filtered external solution (NaCl 140 mM, KC1 4 mM, MgC12 1 mM, CaC12 2 mM, D-Glucose monohydrate 5 mM, Hepes/NaOH 10 mM, pH 7.4, Osmolality :298+/-5 mOsmol).

[00363] The PC®-1 chip of the Port-a-Patch® is filled with 5 JL of internal solution (KC1

50 mM, NaCl 10 mM, KF1 60 mM, EGTA 20 mM, Hepes/KOH 10 mM, pH 7.2, Osmolality: 285+/- 5 mOsmol) and it is screwed onto the chip holder. The Faraday cage is then fixed on the chip holder, such that the external electrode is placed near to the chip aperture. 5 μΐ _^ of external solution is added to the center of the aperture so that the external electrode is also in contact with the solution.

[00364] The experiment is be initiated. Once the set threshold of resistance attained (i.e., 2- 3.5 MOhm), 5 μΐ _^ of cell suspension is added in the middle of the external solution droplet after the Suction Control unit has generated the suction pulse. The suction automatically attracts a cell to the aperture, resulting in an increase in the chip resistance. When the cell is captured and the set threshold for the resistance is reached, the software recognizes this increase in resistance and proceeds to the next step of the sealing procedure. 20 μΐ _^ of seal enhancer solution (NaCl 80 mM, KC1 4 mM, MgC12 10 mM, CaC12 35 mM, Hepes (Na+salt)/HCl pH 7.4, Osmolality: 298+Λ5 mOsmol) is added 2-3 times. When the threshold resistance is reached, Patch Control automatically moves to the step of improving the seal. When the desirable resistance (Rpip) is reached, whole cell mode is attained and maintained.

[00365] Finally, hERG protocol is selected to run the experiment. The seal enhancer solution is replaced with 20 μΙ_, external solution after 2-4 rinses and then the test item is added (from lower to higher concentration) and checked for current inhibition. All the experiments are performed at ambient temperature (22-25°C).

[00367] Once the stable current is attained (at least 2-5 minutes) vehicle control is added and the current measured till the stable current is achieved. 3 - 5 consecutive data points from the last stable current phase are considered for further analysis. The test concentrations are analyzed from the lower to the higher concentrations (1, 3, 10 and 30 μΜ) in duplicates till stable current is achieved along with positive control. The system performs on-line analysis for several parameters which include functions that acquire data from traces and functions that perform calculations on the results of other functions.
