Description

BACKGROUND OF THE INVENTION

This invention relates to cyclylamine sulfonamide derivatives which are β 3 adrenergic receptor agonists useful for the treatment of metabolic disorders related to insulin resistance or hyperglycemia (typically associated with obesity or glucose intolerance), atherosclerosis, gastrointestinal disorders, neurogenetic inflammation, glaucoma, ocular hypertension, and and frequent urination, and are particularly useful in the treatment or inhibition of type II diabetes.

The subdivision of β adrenergic receptors (β-AR) into β 1 - and β 2 -AR has led to the development of β 1 - and β 2 - antagonists and/or agonists which have been useful for the treatment of cardiovascular disease and asthma. The recent discovery of “atypical” receptors, later called β 3 -AR, has led to the development of β 3 -AR agnoists which may be potentially useful as antiobesity and antidiabetic agents. For recent reviews on β 3 -AR agnoists , see: 1. A. D. Strosberg, Annu. Rev. Pharmacol. Toxicol. 1997, 37, 421; 2. A. E. Weber, Ann. Rep. Med. Chem. 1998, 33, 193; 3. C. P. Kordik and A. B. Reitz, J. Med. Chem. 1999, 42, 181; 4. C. Weyer, J. F. Gautier and E. Danforth, Diabetes and Metabolism, 1999, 25, 11.

Compounds that are potent and selective β 3 agonists, may be potentially useful antiobesity agents. Low levels or lack of β 1 and β 2 -agonistic properties will minimize or eliminate the adverse side effects that are associated with β 1 and β 2 agonistic activities, i.e. increased heart rate, and muscle tremor, respectively.

Early developments in the β 3 -agonist field are described in European patent 427480, U.S. Pat. Nos. 4,396,627, 4,478,849, 4,999,377, 5,153,210. Although the early developments purport to claim compounds with greater β 3 -AR selectivity over the β 1 - and β 2 -AR. However, clinical trials in humans with those early developed β 3 -agonists have, so far, not been successful.

More recently, potent and selective human β 3 agonists have been described in several patents and published applications: WO 98/32753, WO 97/46556, WO 97/37646, WO 97/15549, WO 97/25311, WO 96/16938, WO 95/29159, European Patents 659737, 801060, 714883, 764640, 827746, and U.S. Pat. Nos. 5,561,142, 5,705,515, 5,436,257, and 5,578,620. These compounds were evaluated in Chinese hamster ovary (CHO) cells test procedures, expressing cloned human β3 receptors, which predict the effects that can be expected in humans (Granneman et al., Mol Pharmacol., 1992, 42, 964; Emorine et al., Science, 1989, 245, 1118; Liggett Mol. Pharmacol, 1992, 42, 634).

β 3 -Adrenergic agonists also are useful in controlling the frequent urge of urination. It has been known that relaxation of the bladder detrusor is under beta adrenergic control (Li JH, Yasay GD and Kau ST Pharmacology 1992; 44: 13-18). Beta-adrenoceptor subtypes are in the detrusor of guinea-pig urinary bladder. Recently, a number of laboratories have provided experimental evidence of β 3 adrenergic receptors in a number of animal species including human (Yamazaki Y, Takeda H, Akahane M, Igawa Y, et al. Br. J. Pharmacol. 1998; 124: 593-599), and that activation of the β 3 receptor subtype by norepinephrine is responsible for relaxation of the urinary bladder.

Urge urinary incontinence is characterized by abnormal spontaneous bladder contractions that can be unrelated to bladder urine volume. Urge urinary incontinence is often referred to hyperactive or unstable bladder. Several etiologies exist and fall into two major categories, myogenic and neurogenic. The myogenic bladder is usually associated with detrusor hypertrophy secondary to bladder outlet obstruction, or with chronic urinary tract infection. Neurogenic bladders are associated with an uninhibited micturition reflex. An upper motor neuron disease is usually the underlying cause. In either case, the disease is characterized my abnormal spontaneous contractions that result in an abnormal sense of urinary urgency and involuntary urine loss. At present, the most common therapy for hyperactive bladder includes the use of antimuscarinic agents to block the action of the excitatory neurotransmitter acetylcholine. While effective in neurogenic bladders, their utility in myogenic bladders is questionable. In addition, due to severe dry mouth side-effects associated with antimuscarinic therapy, the patient compliance with these agents is only approximately 30%.

In the bladder, β 3 adrenergic receptor agonists activate adenylyl cyclase and generate cAMP through the G-protein coupled β 3 receptor. The resulting phosphorylation of phospholamban/calcium ATPase enhances uptake of calcium into the sarcoplasmic reticulum. The decrease in intracellular calcium inhibits bladder smooth muscle contractility.

It is suggested therefore, that activation of the β 3 adrenergic receptor in the urinary bladder will inhibit abnormal spontaneous bladder contractions and be useful for the treatment of bladder hyperactivity. Note, that unlike the antimuscarinics, β 3 adrenergic receptor agonists would be expected to be active against both neurogenic and myogenic etiologies.

Despite all these recent developments there is still no single therapy available for the treatment of type II diabetes (NIDDM), obesity, atherosclerosis, gastrointestinal disorders, neurogenetic inflammation, frequent urination and related diseases. A potent and selective β 3 adrenergic receptor agonist is therefore highly desirable for the potential treatment of such disease states.

The compounds of this invention were be prepared according to the following schemes from commercially available starting materials or starting materials which can be prepared using literature procedures. These schemes show the preparation of representative compounds of this invention.

As shown in Scheme 1, reaction of an oxo-cyclylamine 1 (e.g. 4-piperidone, m=n=2) with a sulfonyl chloride gives the sulfonamide 2 which upon reductive amination with the appropriate ethanolamines 3 gives compound 4 which is a beta-3 adrenergic receptor agonist. A second synthetic route (Scheme 2) involves the di-sulfonylation of a hydroxy-cyclylamine 5, followed by sequential reactions with benzylamine, and oxirane 8, and then hydrogenation to yield the final product. A similar synthesis employing an N-sulfonylation and O-mesylation sequence is shown in Scheme 3. Azetidine derivatives are prepared from 1-(diphenylmethyl)-3-azetidine according to one of the synthetic routes shown in Scheme 4 and Scheme 5.

Many of the aryloxypropanolamines and arylethanolamines used in the above Schemes are commerically available or readily prepared by known methods [e.g., 1. A. Guy, Synthesis, 1992, 821; 2. A. A. Asselin, J. Med. Chem., 1986, 1009; 3. M. S. Berridge et al., Nucl. Med. Biol., 19, 1992, 563; 4. C. D. Jesudason, et al., EP0764640; 5. EP0659737.]. In one method (Scheme 6), equimolar amounts of a substituted phenol and (2S) or (2R)-glycidyl 3-nitrobenzenesulfonate are dissolved in an organic solvent such as acetone or dimethylformamide and treated with a base such as sodium hydride or potassium carbonate for 0.5 to 24 hours at temperatures of 20 to 100° C. to provide the corresponding aryloxyoxiranes. The aryloxyoxiranes are converted to the ethanolamines by regioselective ring opening of the oxirane with lithium azide in a solvent such as hexamethylphosphoramide, followed by reduction with triphenylphosphine or hydrogenation with 10% Pd/C as catalyst. Alternatively, the aryloxyoxiranes can be converted to the ethanolamines by regioselective ring opening of the oxirane with dibenzylamine, followed by hydrogenation with 10% Pd/C as catalyst.

The arylethanolamines used in Schemes 1 and 4 can be prepared according to the methods shown in Scheme 7. Arylmethylketones are converted to the corresponding α-haloketones using known methods [J. March, Advanced Organic Chemistry, 3rd Ed., John Wiley and Sons, New York:1985, p529 and references cited therein]. The haloketones are reduced to the corresponding alcohol which can be protected as the triethylsilyl ether, or converted directly to the ethanolamine by treatment with ammonia or sodium azide followed by reduction. Treatment of the halo silyl ether with benzylamine followed by desilylation and hydrogenation also gives the corresponding arylethanolamine.

The compounds of this invention are useful in treating metabolic disorders related to insulin resistance or hyperglycemia, typically associated with obesity or glucose intolerance. The compounds of this invention are therefore, particularly useful in the treatment or inhibition of type II diabetes. The compounds of this invention are also useful in modulating glucose levels in disorders such as type I diabetes.

The ability of compounds of this invention to treat or inhibit disorders related to insulin resistance or hyperglycemia was established with representative compounds of this invention in the following standard pharmacological test procedures, which measured the binding selectivity to the β 1 , β 2 , and β 3 adrenergic receptors. Binding to the receptors was measured in Chinese Hamster ovary (CHO) cells that were transfected with adrenergic receptors. The following briefly summarizes the procedures used and results obtained.

Transfection of CHO cells with β 1 and β 2 adrenergic receptors: CHO cells were transfected with human β 1 - or β 2 -adrenergic receptors as described in Tate, K. M., , Eur. J. Biochem., 196:357-361 (1991).

Cloning of Human β 3 -AR Genomic DNA: cDNA was constructed by ligating four polymerase chain reaction (PCR) products using the following primers: an ATG-Narl fragment, sense primer 5′-CTTCCCTACCGCCCCACGCGCGATC3′ and anti-sense primer 5′CTGGCGCCCAACGGCCAGTGGCCAGTC3′; a Narl-Accl fragment, 5′TTGGCGCTGATGGCCACTGGCCGTTTG3′ as sense and 5′GCGCGTAGACGAAGAGCATCACGAG3′ as anti-sense primer; an Accli-Styl fragment, sense primer 5′CTCGTGATGCTCTTCGTCTCACGCGC3′ and anti-sense primer 5′GTGAAGGTGCCCATGATGAGACCCAAGG3′ and a Styl-TAG fragment, with sense primer 5′CCCTGTGCACCTTGGGTCTCATCATGG3′ and anti-sense primer 5′CCTCTGCCCCGGTTACCTACCC3′. The corresponding primer sequences are described in Mantzoros, C. S., etal., Diabetes 45: 909-914 (1996). The four fragments are ligated into a pUC 18 plasmid (Gibco-BRL) and sequenced. Full length β 3 AR clones (402 amino acids) containing the last 6 amino acids of hβ 3 — AR are prepared with the β 3 -βARpcDNA3 from ATTC.

Binding Procedure: Clones expressing receptor levels of 70 to 110 fmoles/mg protein were used in the test procedures. CHO cells were grown in 24-well tissue culture plates in Dulbecco's Modified Eagle Media with 10% fetal bovine serum, MEM non-essential amino acids, Penicillin-Streptompycin and Geneticin. On the day of test procedure, growth medium was replaced with preincubation media (Dulbecco's Modified Eagle Media and incubated for 30 minutes at 37° C. Preincubation medium was replaced with 0.2 ml treatment medium containing DMEM media containing 250 μM IBMX (isobutyl-1-methylxantine) plus 1 mM ascorbic acid with test compound dissolved in DMSO. Test compounds were tested over a concentration range of 10 −9 M to 10 −5 M for β 3 cells and 10 −8 to 10 −4 M for β 1 and β 2 transfected cells. Isoproterenol (10 −5 M) was used as an internal standard for comparison of activity. Cells were incubated at 37° C. on a rocker for 30 min with the β 3 cells and 15 min for β 1 and β 2 cells. Incubation was stopped with the addition of 0.2N HCl and neutralized with 2.5N NaOH. The plates, containing the cells and neutralized media, were stored at −20 degrees celsius until ready to test for cAMP using the SPA test kit (Amersham).

Data Analysis and Results: Data collected from the SPA test procedure were analyzed as per cent of the maximal isoproterenol response at 10 −5 M. Activity curves were plotted using the SAS statistical and graphics software. EC 50 values were generated for each compound and the maximal response (IA) developed for each compound is compared to the maximal response of isoproternol at 10 −5 M from the following formula: $$ IA = % ⁢   ⁢ activity ⁢   ⁢ compound % ⁢   ⁢ activity ⁢   ⁢ isoproterenol

The following table shows the EC 50 and IA values for the representative compounds of this invention that were evaluated in this standard pharmacological test procedure that measured binding selectivity at that β-adrenergic receptors.

Capsules may contain mixtures of the active compound(s) with inert fillers and/or diluents such as the pharmaceutically acceptable starches (e.g. corn, potato or tapioca starch), sugars, artificial sweetening agents, powdered celluloses, such as crystalline and microcrystalline celluloses, flours, gelatins, gums, etc. Useful tablet formulations may be made by conventional compression, wet granulation or dry granulation methods and utilize pharmaceutically acceptable diluents, binding agents, lubricants, disintegrants, suspending or stabilizing agents, including, but not limited to, magnesium stearate, stearic acid, talc, sodium lauryl sulfate, microcrystalline cellulose, carboxymethylcellulose calcium, polyvinylpyrrolidone, gelatin, alginic acid, acacia gum,, xanthan gum, sodium citrate, complex silicates, calcium carbonate, glycine, dextrin, sucrose, sorbitol, dicalcium phosphate, calcium sulfate, lactose, kaolin, mannitol, sodium chloride, talc, dry starches and powdered sugar. Oral formulations herein may utilize standard delay or time release formulations to alter the absorption of the active compound(s).

In some cases it may be desirable to administer the compounds directly to the airways in the form of an aerosol.

The compounds of this invention may also be administered parenterally or intraperitoneally. Solutions or suspensions of these active compounds as a free base or pharmacologically acceptable salt can be prepared in water suitably mixed with a surfactant such as hydroxy-propylcellulose. Dispersions can also be prepared in glycerol, liquid polyethylene glycols and mixtures thereof in oils. Under ordinary conditions of storage and use, these preparation contain a preservative to prevent the growth of microorganisms.

The pharmaceutical forms suitable for injectable use include sterile aqueous solutions or dispersions and sterile powders for the extemporaneous preparation of sterile injectable solutions or dispersions. In all cases, the form must be sterile and must be fluid to the extent that easy syringability exists. It must be stable under the conditions of manufacture and storage and must be preserved against the contaminating action of microorganisms such as bacteria and fungi. The carrier can be a solvent or dispersion medium containing, for example, water, ethanol, polyol (e.g., glycerol, propylene glycol and liquid polyethylene glycol), suitable mixtures thereof, and vegetable oils.

Suppository formulations may be made from traditional materials, including cocoa butter, with or without the addition of waxes to alter the suppository's melting point, and glycerin. Water soluble suppository bases, such as polyethylene glycols of various molecular weights, may also be used.

The compounds of the present invention also possess utility for increasing lean meat deposition and/or improving lean meat to fat ratio in edible animals, i.e. ungulate animals and poultry.

Animal feed compositions effective for increasing lean meat deposition and for improving lean meat to fat ratio in poultry, swine, sheep, goats, and cattle are generally prepared by mixing the compounds of the present invention with a sufficient amount of animal feed to provide from about 1 to 1000 ppm of the compound in the feed. Animal feed supplements can be prepared by admixing about 75% to 95% by weight of a compound of the present invention with about 5% to about 25% by weight of a suitable carrier or diluent. Carriers suitable for use to make up the feed supplement compositions include the following: alfalfa meal, soybean meal, cottonseed oil meal, linseed oil meal, sodium chloride, cornmeal, cane molasses, urea, bone meal, corncob meal and the like. The carrier promotes a uniform distribution of the active ingredients in the finished feed into which the supplement is blended. It thus performs an important function by ensuring proper distribution of the active ingredient throughout the feed. The supplement is used as a top dressing for the feed, it likewise helps to ensure uniformity of distribution of the active material across the top of the dressed feed.

The preferred medicated swine, cattle, sheep and goat feed generally contain from 0.01 to 400 grams of active ingredient per ton of feed, the optimum amount for these animals usually being about 50 to 300 grams per ton of feed. The preferred poultry and domestic pet feed usually contain about 0.01 to 400 grams and preferably 10 to 400 grams of active ingredient per ton of feed.

For parenteral administration the compounds of the present invention may be prepared in the form of a paste or a pellet and administered as an implant, usually under the skin of the head or ear of the animal in which increase in lean meat deposition and improvement in lean mean to fat ratio is sought. In general, parenteral administration involves injection of a sufficient amount of the compounds of the present invention to provide the animal with 0.001 to 100 mg/kg/day of body weight of the active ingredient. The preferred dosage for swine, cattle, sheep and goats is in the range of from 0.001 to 50 mg/kg/day of body weight of active ingredient; whereas, the preferred dose level for poultry and domestic pets is usually in the range of from 0.001 to 35 mg/kg/day of body weight.

Paste formulations can be prepared by dispersing the active compounds in a pharmaceutically acceptable oil such as peanut oil, sesame oil, corn oil or the like. Pellets containing an effective amount of the compounds of the present invention can be prepared by admixing the compounds of the present invention with a diluent such as carbowax, carnuba wax, and the like, and a lubricant, such as magnesium or calcium stearate, can be added to improve the pelleting process. It is, of course, recognized that more than one pellet may be administered to an animal to achieve the desired dose level which will provide the increase in lean meat deposition and improvement in lean meat to fat ratio desired. Moreover, it has been found that implants may also be made periodically during the animal treatment period in order to maintain the proper drug level in the animal's body. For the poultry and swine raisers, using the method of the present invention yields leaner animals.

Additionally, the compounds of this invention are useful in increasing the lean mass to fat ratio in domestic pets, for the pet owner or veterinarian who wishes to increase leanness and trim unwanted fat from pet animals, the present invention provides the means by which this can be accomplished.
