TECHNICAL FIELD

[0002] This invention relates to inhibiting 11.beta.HSD1.

BACKGROUND

[0003] Diabetes is generally characterized by relatively high levels of plasma glucose (hyperglycemia) in the fasting state. Patients having type 2 diabetes (non-insulin dependent diabetes mellitus (NIDDM)) produce insulin (and even exhibit hyperinsulinemia), whilst demonstrating hyperglycemia.

[0004] Type 2 diabetics can often develop insulin resistance, in which the effect of insulin in stimulating glucose and lipid metabolism is diminished. Further, patients having insulin resistance, but have not developed type 2 diabetes, are also at risk of developing Syndrome X (metabolic syndrome). Syndrome X is characterized by insulin resistance, along with obesity (e.g., abdominal obesity), hyperinsulinemia, high blood pressure, relatively low HDL and relatively high VLDL.

[0005] Glucocorticoids (e.g., cortisol in humans, corticosterone in rodents) are counter regulatory hormones that oppose the action of insulin. It is established that glucocorticoid activity is controlled at the tissue level by intracellular interconversion of active cortisol and inactive cortisone by the 11-beta hydroxysteroid dehydrogenases, 11.beta.HSD1, which activates cortisone and 11.beta.HSD2, which inactivates cortisol. Excess levels of glucocorticoids (e.g., cortisol) can cause metabolic complications. For example, excess cortisol is associated with disorders including NIDDM, obesity, dyslipidemia, insulin resistance, and hypertension.

[0006] It is believed that inhibition of 11.beta.HSD1 can reduce the effects of excessive amounts of 11.beta.-hydroxysteroids, e.g., cortisol, and therefore can be useful for the treatment and control of diseases mediated by abnormally high levels of cortisol and other 11.beta.-hydroxysteroids, e.g., NIDDM, obesity, dyslipidemia, and hypertension.

[0500] It is understood that the actual electronic structure of some chemical entities cannot be adequately represented by only one canonical form (i.e. Lewis structure). While not wishing to be bound by theory, the actual structure can instead be some hybrid or weighted average of two or more canonical forms, known collectively as resonance forms or structures. Resonance structures are not discrete chemical entities and exist only on paper. They differ from one another only in the placement or "localization" of the bonding and nonbonding electrons for a particular chemical entity. It can be possible for one resonance structure to contribute to a greater extent to the hybrid than the others. Thus, the written and graphical descriptions of the embodiments of the present invention are made in terms of what the art recognizes as the predominant resonance form for a particular species.

[0512] The compounds and compositions described herein can, for example, be administered orally, parenterally (e.g., subcutaneously, intracutaneously, intravenously, intramuscularly, intraarticularly, intraarterially, intrasynovially, intrasternally, intrathecally, intralesionally and by intracranial injection or infusion techniques), by inhalation spray, topically, rectally, nasally, buccally, vaginally, via an implanted reservoir, by injection, subdermally, intraperitoneally, transmucosally, or in an ophthalmic preparation, with a dosage ranging from about 0.01 mg/Kg to about 1000 mg/Kg, (e.g., from about 0.01 to about 100 mg/kg, from about 0.1 to about 100 mg/Kg, from about 1 to about 100 mg/Kg, from about 1 to about 10 mg/kg) every 4 to 120 hours, or according to the requirements of the particular drug. The interrelationship of dosages for animals and humans (based on milligrams per meter squared of body surface) is described by Freireich et al., Cancer Chemother. Rep. 50, 219 (1966). Body surface area may be approximately determined from height and weight of the patient. See, e.g., Scientific Tables, Geigy Pharmaceuticals, Ardsley, N.Y., 537 (1970). In certain embodiments, the compositions are administered by oral administration or administration by injection. The methods herein contemplate administration of an effective amount of compound or compound composition to achieve the desired or stated effect. Typically, the pharmaceutical compositions of this invention will be administered from about 1 to about 6 times per day or alternatively, as a continuous infusion. Such administration can be used as a chronic or acute therapy. The amount of active ingredient 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. A typical preparation will contain from about 5% to about 95% active compound (w/w). Alternatively, such preparations contain from about 20% to about 80% active compound.

[0513] Lower or higher doses than those recited above may be required. Specific dosage and treatment regimens 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 status, sex, diet, time of administration, rate of excretion, drug combination, the severity and course of the disease, condition or symptoms, the patient's disposition to the disease, condition or symptoms, and the judgment of the treating physician.

[0514] Upon improvement of a patient's condition, a maintenance dose of a compound, composition or combination of this invention may be administered, if necessary. Subsequently, the dosage or frequency of administration, or both, may be reduced, as a function of the symptoms, to a level at which the improved condition is retained when the symptoms have been alleviated to the desired level. Patients may, however, require intermittent treatment on a long-term basis upon any recurrence of disease symptoms.

[0515] The compositions of this invention may contain any conventional non-toxic pharmaceutically-acceptable carriers, adjuvants or vehicles. In some cases, the pH of the formulation may be adjusted with pharmaceutically acceptable acids, bases or buffers to enhance the stability of the formulated compound or its delivery form.

[0516] The compositions may be in the form of a sterile injectable preparation, for example, as a sterile injectable aqueous or oleaginous suspension. This suspension may be formulated according to techniques known in the art using suitable dispersing or wetting agents (such as, for example, Tween 80) 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 mannitol, water, Ringer's solution 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 may be employed including synthetic mono- or diglycerides. 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 polyoxyethylated versions. These oil solutions or suspensions may also contain a long-chain alcohol diluent or dispersant, or carboxymethyl cellulose or similar dispersing agents which are commonly used in the formulation of pharmaceutically acceptable dosage forms such as emulsions and or suspensions. Other commonly used surfactants such as Tweens or Spans and/or other similar 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.

[0517] The compositions of this invention may be orally administered in any orally acceptable dosage form including, but not limited to, capsules, tablets, emulsions and aqueous suspensions, dispersions and solutions. In the case of tablets for oral use, carriers which are 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 corn starch. When aqueous suspensions and/or emulsions are administered orally, the active ingredient may be suspended or dissolved in an oily phase is combined with emulsifying and/or suspending agents. If desired, certain sweetening and/or flavoring and/or coloring agents may be added.

[0518] The compositions of this invention may also be administered in the form of suppositories for rectal administration. These compositions can be prepared by mixing a compound of this invention with a suitable non-irritating excipient which is solid at room temperature but liquid at the rectal temperature and therefore will melt in the rectum to release the active components. Such materials include, but are not limited to, cocoa butter, beeswax and polyethylene glycols.

[0519] Topical administration of the compositions of this invention is useful when the desired treatment involves areas or organs readily accessible by topical application. For application topically to the skin, the composition should be formulated with a suitable ointment containing the active components suspended or dissolved in a carrier. Carriers for topical administration of the compounds of this invention include, but are not limited to, mineral oil, liquid petroleum, white petroleum, propylene glycol, polyoxyethylene polyoxypropylene compound, emulsifying wax and water. Alternatively, the composition can be formulated with a suitable lotion or cream containing the active compound suspended or dissolved in a carrier with suitable emulsifying agents. 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. The compositions of this invention may also be topically applied to the lower intestinal tract by rectal suppository formulation or in a suitable enema formulation.

[0520] Topically-transdermal patches are also included in this invention. Also within the invention is a patch to deliver active chemotherapeutic combinations herein. A patch includes a material layer (e.g., polymeric, cloth, gauze, bandage) and the compound of the formulae herein as delineated herein. One side of the material layer can have a protective layer adhered to it to resist passage of the compounds or compositions. The patch can additionally include an adhesive to hold the patch in place on a subject. An adhesive is a composition, including those of either natural or synthetic origin, that when contacted with the skin of a subject, temporarily adheres to the skin. It can be water resistant. The adhesive can be placed on the patch to hold it in contact with the skin of the subject for an extended period of time. The adhesive can be made of a tackiness, or adhesive strength, such that it holds the device in place subject to incidental contact, however, upon an affirmative act (e.g., ripping, peeling, or other intentional removal) the adhesive gives way to the external pressure placed on the device or the adhesive itself, and allows for breaking of the adhesion contact. The adhesive can be pressure sensitive, that is, it can allow for positioning of the adhesive (and the device to be adhered to the skin) against the skin by the application of pressure (e.g., pushing, rubbing), on the adhesive or device.

[0521] The compositions of this invention may 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 solubilizing or dispersing agents known in the art.

[0522] A composition having the compound of the formulae herein and an additional agent (e.g., a therapeutic agent) can be administered using any of the routes of administration described herein. In some embodiments, a composition having the compound of the formulae herein and an additional agent (e.g., a therapeutic agent) can be administered using an implantable device. Implantable devices and related technology are known in the art and are useful as delivery systems where a continuous, or timed-release delivery of compounds or compositions delineated herein is desired. Additionally, the implantable device delivery system is useful for targeting specific points of compound or composition delivery (e.g., localized sites, organs). Negrin et al., Biomaterials, 22 (6):563 (2001). Timed-release technology involving alternate delivery methods can also be used in this invention. For example, timed-release formulations based on polymer technologies, sustained-release techniques and encapsulation techniques (e.g., polymeric, liposomal) can also be used for delivery of the compounds and compositions delineated herein.

[0523] The invention will be further described in the following examples. It should be understood that these examples are for illustrative purposes only and are not to be construed as limiting this invention in any manner.

1-[(3-chlorophenyl)sulfonyl]-4-[2-(trifluoromethyl)phenyl]piperidine

[0917] Step 14A: 1-Benzyl-4-[2-(trifluoromethyl)phenyl]piperidin-4-ol. Following the procedure of N. I. Carruthers et al. (J. Med. Chem. 2005, 48, 1857-1872), to a -78.degree. C. solution of 2-bromobenzotrifluoride (12.9 g, 7.8 mL, 57 mmol) in THF (225 mL) was added dropwise a solution of n-BuLi (2.5 M in hexanes, 26 mL, 65 mmol) over 10 min. After 1 h, the reaction mixture was stirred at 0.degree. C. for 10 min, recooled to -78.degree. C., and a solution of N-benzyl-4-piperidone (10.7 g, 57 mmol) in THF (40 mL) was added dropwise via addition funnel over 10 min. After 2 h at -78.degree. C., sat. NH.sub.4Cl solution (200 mL) was added and the mixture was warmed to room temperature. The aqueous phase was extracted with EtOAc (2.times.200 mL). The organic phase was washed with H2O (200 mL) and brine (150 mL), dried (MgSO.sub.4), and concentrated. Flash chromatography afforded the alcohol (2.7 g), a yellow oil, slightly contaminated with piperidone starting material, in .about.15% yield.

[0918] Step 14B: 1-Benzyl-4-[2-(trifluoromethyl)phenyl]-1,2,3,6-tetrahydropyridine. Thionyl chloride (10 mL) was added slowly dropwise to the alcohol from Step 14A (4.9 g, 14.6 mmol). After 2 h, the mixture was concentrated, diluted with CH.sub.2Cl.sub.2 (50 mL), and added slowly to a stirred solution of sat. NaHCO.sub.3 (200 mL). The aqueous phase was separated and extracted with CH.sub.2Cl.sub.2 (2.times.150 mL). The combined organic extracts were washed with H.sub.2O (2.times.150 mL) and brine (150 mL), dried (MgSO.sub.4), and concentrated. Flash chromatography (elution with 10-30% EtOAc-hexanes) afforded the olefin (2.75 g), a yellow oil, in 59% yield. .sup.1H NMR (400 MHz, CDCl.sub.3) .delta. 2.38 (dd, J=4.5, 2.8 Hz, 2H), 2.70 (t, J=5.7 Hz, 2H), 3.14 (q, J=2.9 Hz, 2H), 3.66 (s, 2H), 5.57 (s, 1H), 7.22-7.30 (m, 2H), 7.31-7.42 (m, 5H), 7.47 (t, J=7.6 Hz, 1H), 7.63 (d, J=7.1 Hz, 1H).

[0919] Step 14C: Following the procedure of N. I. Carruthers et al. (J. Med. Chem. 2005, 48, 1857-1872), the olefin from Step 14B (2.99 g, 9.4 mmol) was dissolved in EtOH (50 mL) and transferred to a Parr shaker bottle. 10% Pd/C (wet Degussa, 3.0 g) was added, and the mixture was hydrogenated at 50 psi for 16 h. The mixture was filtered, fresh Pd/C (3.0 g) was added, and the mixture was hydrogenated at 50 psi for 2 d. The mixture was filtered and concentrated to afford a beige solid that was purified by flash chromatography (elution with 10% MeOH--CH.sub.2Cl.sub.2 to 0.1% E.sub.t3N-10% MeOH--CH.sub.2Cl.sub.2) to afford the amine (1.24 g), a yellow oil, contaminated with Et.sub.3N, in .about.57% yield. .sup.1H NMR (400 MHz, CDCl.sub.3) .delta. 1.62-1.87 (m, 4H), 2.70-2.84 (m, 2H), 2.97-3.10 (m, 1H), 3.19 (d, J=11.6 Hz, 2H), 7.18-7.35 (m, 1H), 7.44-7.56 (m, 2H), 7.61 (d, J=7.8 Hz, 1H).

[0920] Step 14D: To a solution of the amine from Step 14C (150 mg, 0.65 mmol) in CH.sub.2Cl.sub.2 (4 mL) was added 3-chlorobenzenesulfonyl chloride (165 mg, 0.11 mL, 0.78 mmol) and saturated NaHCO.sub.3 (2 mL). The biphasic mixture was stirred for 6 h. The reaction mixture was diluted with CH.sub.2Cl.sub.2 (3 mL) and poured into a Phase Separator cartridge. The organic phase was concentrated and purified by flash chromatography (elution with 2-10% EtOAc-hex). Lyophilization then afforded the title compound (176 mg), a white solid, in 67% yield.

[1045] Representative Procedure

[1046] Step 22A: 4-Oxo-piperidine-1-carboxylic acid tert-butyl ester (2.99 g, 15 mmole), morpholine (1.4 mL, 15.8 mmole), acetic acid (1.0 mL, 18 mmole) were dissolved in 30 mL dichloroethane and sodium triacetoxyborohydride (6.36 g, 30 mmole) was added and the reaction mixture was stirred at room temperature for 2 hours. The mixture was diluted with dichloromethane and then washed with 2N NaOH, water, and dried (MgSO.sub.4). Filtration and evaporation gave 3.84 g (95%) 4-morpholin-4-yl-piperidine-1-carboxylic acid tert-butyl ester as a colorless oil that solidified on standing.

[1047] Step 22B: 4-morpholin-4-yl-piperidine-1-carboxylic acid tert-butyl ester (3.85 g, 14.2) was dissolved in 25 mL dichloromethane and 20 mL trifluoroacetic acid was added and stirred at room temperature for 90 minutes. The reaction mixture was then evaporated then co-evaporated twice with dichloromethane. The semisolid residue was triturated with 75 mL ether, stirred at room temperature 1 hour, then filtered to give 5.03 g of 4-piperidin-4-yl-morpholine, bis-trifluoroacetic acid salt (89%) as a white solid.

[1048] Step 22C: 4-piperidin-4-yl-morpholine, bis-trifluoroacetic acid salt (299 mg, 0.75 mmole) and DIPEA (0.54 mL, 3 mmole) were dissolved in 2 mL dichloromethane and 2-chlorophenylsulfonyl chloride (189 mg, 0.9 mmole) was added and the reaction mixture stirred at room temperature overnight. The reaction was diluted with dichloromethane, washed with water and dried over Na.sub.2SO.sub.4. The organic layer was evaporated then dissolved in 5 mL EtOAc then 2-3 mL 1M HCl/EtOAc was added and stirred at room temperature. The resulting solid was filtered to give 225 mg (75%) of 4-{1-[(2-chlorophenyl)sulfonyl]piperidin-4-yl}morpholine, hydrochloric acid salt as a white solid.
