Description

BACKGROUND OF THE INVENTION

The present invention relates to a class of carbocyclic compounds that are useful as potassium channel inhibitors to treat autoimmune disorders, cardiac arrhythmias and the like.

Immunoregulatory abnormalities have been shown to exist in a wide variety of autoimmune and chronic inflammatory diseases, including systemic lupus erythematosis, chronic rheumatoid arthritis, type I and II diabetes mellitus, inflammatory bowel disease, biliary cirrhosis, uveitis, multiple sclerosis and other disorders such as Crohn's disease, ulcerative colitis, bullous pemphigoid, sarcoidosis, psoriasis, ichthyosis, Graves ophthalmopathy and asthma.

Although the underlying pathogenesis of each of these conditions may be quite different, they have in common the appearance of a variety of autoantibodies and self-reactive lymphocytes. Such self-reactivity may be due, in part, to a loss of the homeostatic controls under which the normal immune system operates. Similarly, following a bone-marrow or an organ transplantation, the host lymphocytes recognize the foreign tissue antigens and begin to produce antibodies which lead to graft rejection.

One end result of an autoimmune or a rejection process is tissue destruction caused by inflammatory cells and the mediators they release. Anti-inflammatory agents such as NSAID's act principally by blocking the effect or secretion of these mediators but do nothing to modify the immunologic basis of the disease. On the other hand, cytotoxic agents, such as cyclophosphamide, act in such a nonspecific fashion that both the normal and autoimmune responses are shut off. Indeed, patients treated with such nonspecific immunosuppressive agents are as likely to succumb from infection as they are from their autoimmune disease.

Cyclosporin A (CsA), which was approved by the US FDA in 1983 is currently the leading drug used to prevent rejection of transplanted organs. In 1993, FK-506 (Prograf) was approved by the US FDA for the prevention of rejection in liver transplantation. CsA and FK-506 act by inhibiting the body's immune system from mobilizing its vast arsenal of natural protecting agents to reject the transplant's foreign protein. In 1994, CsA was approved by the US FDA for the treatment of severe psoriasis and has been approved by European regulatory agencies for the treatment of atopic dermatitis. Though they are effective in fighting transplant rejection, CsA and FK-506 are known to cause several undesirable side effects including nephrotoxicity, neurotoxicity, and gastrointestinal discomfort. Therefore, a selective immunossuppressant without these side effects still remains to be developed. Potassium channel inhibitors promise to be the solution to this problem.

The importance of potassium channels was first recognized almost fifty years ago when Hodgkin and Huxley discovered that potassium ions contributed to the current that excited the squid giant axon. Research in the area, however, was hampered by the lack of selective, high affinity ligands for potassium channels. But the advent of recombinant DNA techniques and single cell and whole cell voltage clamp techniques has changed the slow pace of the field. Potassium channels have turned out to be the most diverse family of ion channels discovered to date. They modulate a number of cellular events such as muscle contraction, neuro-endocrine secretion, frequency and duration of action potentials, electrolyte homeostasis, and resting membrane potential.

Potassium channels have been classified according to their biophysical and pharmacological characteristics. Salient among these are the voltage dependent potassium channels, such as K v 1. The K v 1 class of potassium channels is further subdivided depending on the molecular sequence of the channel, for example K v 1.1, K v 1.3, K v 1.5. Functional voltage-gated K + channels can exist as multimeric structures formed by the association of either identical or dissimilar subunits. This phenomena is thought to account for the wide diversity of K + channels. However, subunit compositions of native K + channels and the physiologic role that particular channels play are, in most cases, still unclear.

Membrane depolarization by K v 1.3 inhibition has been shown to be an effective method to prevent T-cell proliferation and therefore has applications in many autoimmune conditions. Inhibition of K + channels in the plasma membrane of human T-lymphocytes has been postulated to play a role in eliciting immunosuppressive responses by regulating intracellular Ca ++ homeostasis, which has been found to be important in T-cell activation.

The K v 1.3 voltage-gated potassium channel is found in neurons, blood cells, osteoclasts and T-lymphocytes. The Chandy and Cahalan laboratories proposed a hypothesis that blocking the K v 1.3 channel would elicit an immunosuppressant response. (Chandy et al., J. Exp. Med . 160, 369, 1984; Decoursey et al., Nature, 307, 465, 1984). However, the K+ channel blockers employed in their studies were non-selective. Until research with the peptide margatoxin, a peptide found in scorpion venom, no specific inhibitor of the K v 1.3 channel existed to test this hypothesis. Although a laboratory (Price et al., Proc. Natl. Acad. Sci. USA , 86, 10171, 1989) showed that charybdotoxin would block K v 1.3 in human T cells, charybdotoxin was subsequently shown to inhibit four different K + channels (K v 1.3 and three distinct small conductance Ca ++ activated K + channels) in human T-lymphocytes, limiting the use of this toxin as a probe for the physiological role of K v 1.3 (Leonard et al., Proc. Natl. Acad. Sci. USA , 89, 10094, 1992). Margatoxin, on the other hand, blocks only K v 1.3 in T-cells, and has immunosuppressant activity in both in vitro and in vivo models. (Lin et al., J. Exp. Med , 177, 637, 1993). The therapeutic utility of this compound, however, is limited by its potent toxicity. Recently, a class of compounds has been reported that may be an attractive alternative to the above-mentioned drugs, see for example U.S. Pat. Nos. 5,670,504; 5,631,282; 5,696,156; 5,679,705; and 5,696,156. While addressing some of the activity/toxicity problems of previous drugs, these compounds tend to be of large molecular weight and are generally produced by synthetic manipulation of a natural product, isolation of which is cumbersome and labor intensive.

Atrial fibrillation (AF) is the most common sustained cardiac arrhythmia in clinical practice and is likely to increase in prevalence with the aging of the population. Currently, AF affects more than 1 million Americans annually, represents over 5% of all admissions for cardiovascular diseases and causes more than 80,000 strokes each year in the United States. While AF is rarely a lethal arrhythmia, it is responsible for substantial morbidity and can lead to complications such as the development of congestive heart failure or thromboembolism. Currently available Class I and Class III antiarrhythmic drugs reduce the rate of recurrence of AF, but are of limited use because of a variety of potentially adverse effects including ventricular proarrhythmia. Because current therapy is inadequate and fraught with side effects, there is a clear need to develop new therapeutic approaches.

Antiarrhythmic agents of Class III are drugs that cause a selective prolongation of the duration of the action potential without significant cardiac depression. Available drugs in this class are limited in number. Examples such as sotalol and amiodarone have been shown to possess interesting Class III properties (Singh B. N., Vaughan Williams E. M. “A Third Class Of Anti-Arrhythmic Action: Effects On Atrial And Ventricular Intracellular Potentials And Other Pharmacological Actions On Cardiac Muscle, of MJ 1999 and AH 3747” Br. J. Pharmacol 1970; 39:675-689. and Singh B. N., Vaughan Williams E. M, “The Effect Of Amiodarone, A New Anti-Anginal Drug, On Cardiac Muscle”, Br J. Pharmacol 1970; 39:657-667.), but these are not selective Class III agents. Sotalol also possesses Class II effects which may cause cardiac depression and is contraindicated in certain susceptible patients. Amiodarone, also is not a selective Class III antiarrhythmic agent because it possesses multiple electrophysiological actions and is severely limited by side effects (Nademanee, K. “The Amiodarone Odessey”. J. Am. Coll. Cardiol . 1992; 20:1063-1065.) Drugs of this class are expected to be effective in preventing ventricular fibrillation. Selective class III agents, by definition, are not considered to cause myocardial depression or an induction of arrhythmias due to inhibition of conduction of the action potential as seen with Class I antiarrhythmic agents.

Class III agents increase myocardial refractoriness via a prolongation of cardiac action potential duration. Theoretically, prolongation of the cardiac action potential can be achieved by enhancing inward currents (i.e. Na + or Ca 2+ currents; hereinafter I Na and I Ca , respectively) or by reducing outward repolarizing potassium (K + ) currents. The delayed rectifier (I K ) K + current is the main outward current involved in the overall repolarization process during the action potential plateau, whereas the transient outward (I to ) and inward rectifier (I K1 ) K + currents are responsible for the rapid initial and terminal phases of repolarization, respectively. Cellular electrophysiologic studies have demonstrated that I K consists of two pharmacologically and kinetically distinct K + current subtypes, I Kr (rapidly activating and deactivating) and I Ks (slowly activating and deactivating)(Sanguinetti and Jurkiewicz, Two Components Of Cardiac Delayed Rectifier K+ Current: Differential Sensitivity To Block By Class III Antiarrhythmic Agents, J Gen Physiol 1990, 96:195-215). Class III antiarrhythmic agents currently in development, including d-sotalol, dofetilide (UK-68,798), almokalant (H234/09), E-4031 and methanesulfonamide-N-[1′-6-cyano-1,2,3,4-tetrahydro-2-naphthalenyl)-3,4-dihydro-4-hydroxyspiro[2H-1-benzopyran-2,4′-piperidin]-6yl]monochloride, predominantly, if not exclusively, block I Kr . Although, amiodarone is a blocker of I Ks (Balser J. R. Bennett, P. B., Hondeghem, L. M. and Roden, D. M. “Suppression Of Time-Dependent Outward Current In Guinea Pig Ventricular Myocytes: Actions Of Quinidine And Amiodarone. Circ. Res . 1991, 69:519-529), it also blocks I Na and I Ca , effects thyroid function, is as a nonspecific adrenergic blocker, and acts as an inhibitor of the enzyme phospholipase (Nademanee, K. “The Amiodarone Odessey”. J. Am. Coll. Cardiol . 1992; 20:1063-1065). Therefore, its method of treating arrhythmia is uncertain Most Class III agents that are known to be in development predominantly block I Kr .

Reentrant excitation (reentry) has been shown to be a prominent mechanism underlying supraventricular arrhythmias in man. Reentrant excitation requires a critical balance between slow conduction velocity and sufficiently brief refractory periods to allow for the initiation and maintenance of multiple reentry circuits to coexist simultaneously and sustain AF. Increasing myocardial refractoriness by prolonging action potential duration (APD), prevents and/or terminates reentrant arrhythmias. Most selective Class III antiarrhythmic agents currently in development, such as d-sotalol and dofetilide predominantly, if not exclusively, block I kr , the rapidly activating component of I K found both in atrium and ventricle in man.

Since these I kr blockers increase APD and refractoriness both in atria and ventricle without affecting conduction per se, theoretically they represent potential useful agents for the treatment of arrhythmias like AF. These agents have a liability in that they have an enhanced risk of proarrhythmia at slow heart rates. For example, torsades de points has been observed when these compounds are utilized (Roden, D. M. “Current Status of Class III Antiarrhythmic Drug Therapy”, Am J. Cardiol , 1993; 72:44B-49B). This exaggerated effect at slow heart rates has been termed “reverse frequency-dependence”, and is in contrast to frequency-independent or frequency-dependent actions (Hondeghem, L. M. “Development of Class III Antiarrhythmic Agents”. J. Cadiovasc. Cardiol . 20 (Suppl. 2): S17-S22).

The slowly activating component of the delayed rectifier (I ks ) potentially overcomes some of the limitations of I kr blockers associated with ventricular arrhythmias. Because of its slow activation kinetics however, the role of I ks in atrial repolarization may be limited due to the relatively short APD of the atrium. Consequently, although I ks blockers may provide distinct advantage in the case of ventricular arrhythmias, their ability to affect SVT is considered to be minimal.

The ultra-rapidly activating delayed rectifier K + current (I kur ) is believed to represent the native counterpart to a cloned potassium channel designated Kv1.5 and, while present in human atrium, it appears to be absent in human ventricle. Furthermore, because of its rapidity of activation and limited slow inactivation, I kur is believed to contribute significantly to repolarization in human atrium. Consequently, a specific blocker Of I kur, , that is a compound which blocks Kv1.5, would overcome the short coming of other compounds by prolonging refractoriness by retarding repolarization in the human atrium without causing the delays in ventricular reporlarization that underlie arrhythmogenic afterdepolarizations and acquired long QT syndrome observed during treatment with current Class III drugs.

In intact human atrial myocytes an ultra-rapidly activating delayed rectifier K + current I kur which is also known as the sustained outward current, I sus or I so , has been identified and this current has properties and kinetics identical to those expressed by the human K + channel clone (hKv1.5, HK2) when isolated from human heart and stably expressed in human (HEK-293) cell lines. (Wang, Fermini and Natel, 1993, Circ Res 73:1061-1076; Fedida et al., 1993, Circ Res 73:210-216; Snyders, Tamkun and Bennet, 1993, J Gen Physiol 101:513-543) and originally cloned from rat brain (Swanson et al., 10, Neuron 4:929-939). Although various antiarrythmic agents are now available on the market, those having both satisfactory efficacy and a high margin of safety have not been obtained. For example, antiarrythmic agents of Class I according to the classification scheme of Vaughan-Williams (“Classification Of Antiarrhythmic Drugs” In: Cardiac Arrhythmias, edited by: E. Sandoe, E. Flensted-Jensen, K. Olesen; Sweden, Astra, Sodertalje, pp449-472, 1981) which cause a selective inhibition of the maximum velocity of the upstroke of the action potential (max) are inadequate for preventing ventricular fibrillation. In addition, they have problems regarding safety, namely, they cause a depression of myocardial contractility and have a tendency to induce arrhythmias due to an inhibition of impulse conduction. Beta-adrenoceptor blockers and calcium antagonists which belong to Class II and IV, respectively, have a defect in that their effects are either limited to a certain type of arrhythmia or are contraindicated because of their cardiac depressant properties in certain patients with cardiovascular disease. Their safety, however, is higher than that of the antiarrhythmic agents of Class I.

The method of treatment of atrial arrhythmia presented herein provides for greater safety and efficacy as well preferentially providing treatment at fast heart rates when treatment of this type is most desired.

The compounds of the present invention have asymmetric centers and this invention includes all of the optical isomers and mixtures thereof. Reference to one isomer is intended to apply to both isomers unless specifically indicated otherwise.

In addition compounds with carbon-carbon double bonds may occur in Z- and E-forms with all isomeric forms of the compounds being included in the present invention.

As used herein, the term “alkyl”, unless otherwise indicated, includes those alkyl groups of a designated number of carbon atoms of either a straight, branched, or cyclic configuration (carbocycles). Examples of “alkyl” include methyl, ethyl, propyl, isopropyl, butyl, sec-and tert-butyl, pentyl, hexyl, heptyl, cyclopropyl, cyclobutyl, cyclopentyl, cyclohexyl, cycloheptyl, norbomyl, and the like. “Alkoxy” represents an alkyl group of indicated number of carbon atoms attached through an oxygen bridge, such as methoxy, ethoxy, propoxy, butoxy and pentoxy. The following illustrate the foregoing definitions: “(C 1 -C 3 )-alkyl” may be methyl, ethyl, propyl, isopropyl, or cyclopropyl. Similarly, “O—(C 1 -C 3 )-alkyl” may be methoxy, ethoxy, n-propoxy, i-propoxy, or cyclopropoxy. In some cases, a C 0 designation is used, as in “—(C 0 -C 2 )-alkyl-phenyl.” In such a case, the substituent is intended to be any of the following: phenyl, benzyl, 1-phenylethyl, or 2-phenylethyl. In certain definitions, the alkyl may be substituted with one or more substituents. For example a definition which reads “(C 1 -C 2 )-alkyl, substituted with one or two substitutents selected from oxo, hydroxy, and halo” is intended to include C(O)CH 3 , CH 2 BrCH 3 , CO 2 H, C(OH)CH 3 , CH 2 CH 2 (OH), CH 2 CO 2 H, CHBrCH 2 Cl, CHO, and so on.

“Alkenyl” is intended to include hydrocarbon chains of a specified number of carbon atoms of either a straight- or branched- configuration and at least one unsaturation, which may occur at any point along the chain, such as ethenyl, propenyl, butenyl, pentenyl, dimethyl pentenyl, and the like, and includes E and Z forms, where applicable. “Halogen” and “halo”, as used herein, mean fluoro, chloro, bromo and iodo.

The term “aryl,” unless specifically defined otherwise, is defined as phenyl or naphthyl, unsubstituted or substituted with one, two or three of the substituents selected from the group consisting of halo, hydroxy, alkyl, perfluoroalkyl, alkenyl, alkynyl, alkyloxy, alkyl-S(O) n —, phenyl, phenoxy, cyano, nitro, CO 2 H, CO-alkyl, CO 2 -alkyl, CONR 8 R 9 , and NR 8 R 9 .

The term “heteroaryl” as utilized herein, unless specifically defined otherwise, is intended to include the following: an unsubstituted, monosubstituted, or disubstituted five or six membered aromatic heterocycle containing from 1 to 3 heteroatoms selected from the group consisting of O, N and S and wherein the substituent is halo, hydroxy, alkyl, perfluoroalkyl, alkenyl, alkynyl, alkyloxy, -alkyl-S(O) n —, phenyl, phenoxy, cyano, nitro, CO 2 H, CO-alkyl, CO 2 -alkyl, CONR 8 R 9 , NR 8 R 9 , or a fused benzo or pyridyl group. Heteroaryl groups within the scope of this definition include but are not limited to: acridinyl, carbazolyl, cinnolinyl, quinoxalinyl, pyrrazolyl, indolyl, benzotriazolyl, furanyl, thienyl, benzothienyl, benzofuranyl, quinolinyl, isoquinolinyl, pyrazinyl, pyridazinyl, pyridinyl, pyrimidinyl, and pyrrolyl which are substituted or unsubstituted as defined above.

In the compounds of Formula I, the heteroaryl or aryl groups may be optionally substituted with the substituents listed above at any available carbon atom or nitrogen atom (if present), but compounds bearing certain substitutents, directly substituted to a nitrogen may be relatively unstable and are not preferred. The heteroaryl may also be fused to a second 5-, 6-, or 7-membered ring containing one or two oxygens such as: dioxolanyl, dihydrofuranyl, dihydropyranyl, and dioxanyl. Disubstituted aryl groups may be ortho, para or meta and all three are intended unless specifically defined otherwise.

“Heterocyclyl” is defined as a 3 to 7 atom cyclic, non-aromatic substituent containing from 1 to 3 heteroatoms selected from the group consisting of O, N, and S, which is unsubstituted or substituted with one, two or three substituents selected from the group consisting of halo, hydroxy, alkyl, perfluoroalkyl, alkenyl, alkynyl, alkyloxy, alkyl-S(O) n —, phenyl, phenoxy, cyano, nitro, CO 2 H, COalkyl, CO 2 -alkyl, CONR 8 R 9 , NR 8 R 9 , NR 8 CO-alkyl, oxo, fused benzo, and fused pyridyl group.

Pharmaceutically acceptable salts include both the metallic (inorganic) salts and organic salts; a list of which is given in Remington's Pharmaceutical Sciences , 17th Edition, pg. 1418 (1985). It is well known to one skilled in the art that an appropriate salt form is chosen based on physical and chemical stability, flowability, hydro-scopicity and solubility. As will be understood by those skilled in the art, pharmaceutically acceptable salts include, but are not limited to salts of inorganic acids such as hydrochloride, sulfate, phosphate, diphosphate, hydrobromide, and nitrate or salts of an organic acid such as malate, maleate, fumarate, tartrate, succinate, citrate, acetate, lactate, methanesulfonate, p-toluenesulfonate or palmoate, salicylate and stearate. Similarly pharmaceutically acceptable cations include, but are not limited to sodium, potassium, calcium, aluminum, lithium and ammonium (especially ammonium salts with secondary amines). Preferred salts of this invention for the reasons cited above include potassium, sodium, calcium and ammonium salts. Also included within the scope of this invention are crystal forms, hydrates and solvates of the compounds of Formula I.

Methods for preparing the compounds of this invention are illustrated in the following schemes and examples. Alternative routes will be easily discernible to practitioners in the field. The following abbreviations are used in the schemes: THF (tetrahydrofuran), PPTS (pyridinium p-toluenesulfonate), DEAD (diethylazidodicarboxylate), CDI (carbonyldiimidazole), HMPA (hexamethylphosphoramide), Tf (triflic), Boc (butoxycarbonyl), DMF (dimethylformamide), PCC (pyridinium chlorochromate), and mCPBA (meta-chloroperbenzoic acid).

The protected 4-cyano-4-aryl cyclohexanone precursors which are starting materials to prepare the compounds of this invention are prepared according to procedures described and cited by Swenton, J. S.; Blankenship, R. M.; and Sanitra, R; J. Am. Chemical Soc., 97, 4941, 1975. Some 4-cyano-4-aryl cyclohexanone precursors are commercially available. Reduction of the nitrile group of the cyclohexyl ketal with LiAlH 4 in an aprotic solvent such as tetrahydrofuran (THF) preferrably at elevated temperatures gives the corresponding amine derivative. The amine intermediate is acylated with acid chlorides in aprotic solvents including THF and CH 2 Cl 2 with a base such as triethylamine to give the corresponding benzamides. The acid chlorides, when not purchased, are prepared by stirring the carboxylic acids in reagents such as oxalyl chloride or thionyl chloride. Alternatively, amides can be prepared by reaction of benzoic acids with the amine using the standard coupling conditions as described in March, J.; Advanced Organic Chemistry, 4th ed., John Wiley & Sons, New York, pp. 417-424 (1992).

The ketal group is then removed under dilute acidic conditions. A 2N solution of HCl in THF is frequently used for this transformation. These and other conditions are described in March, J.; Advanced Organic Chemistry, 4th ed., John Wiley & Sons, New York, pp. 372-375 (1992). Alternatively, the ketal group is removed by stirring in acetone with pyridinium p-toluenesulfonate (PPTS).

The ketone group is reduced with sodium borohydride (NaBH 4 ) in solvents such as THF or methanol to give a diastereomeric mixture of alcohols that can be separated by standard chromatography methods. NaBH 4 is utilized to achieve selective reduction of the ketone as described in March, J.; Advanced Organic Chemistry, 4th ed., John Wiley & Sons, New York, pp. 1206-1208 (1992).

An alternate preparation is described in Reaction Scheme C. The cyano ketone is prepared according to procedures described and cited by Swenton, J. S.; Blankenship, R. M.; and Sanitra, R; J. Am. Chemical Soc., 97, 4941, 1975. Reduction to the corresponding amino alcohol occurs with LiAlH 4 in THF, conditions described in March, J.; Advanced Organic Chemistry, 4th ed., John Wiley & Sons, New York, pp. 910-918 and 1206-1208 (1992). With this substrate, the beta (up) alcohol is the predominant isomer. Acylation of the amino group with acids or acid chlorides using procedures described and cited in Reaction Scheme A is quite selective as long as one uses a slight excess of the substrate. Inversion of the beta hydroxy group to the alpha hydroxy group is achieved via a Mitsunobu reaction sequence as reviewed by Mitsunobu in Synthesis, 1-28 (1981).

As depicted in Reaction Scheme D, esters at C1 can be prepared by reaction of an acid chloride with the C1 hydroxy group in a basic solvent such as pyridine. The acid chlorides, when not purchased, are prepared by stirring the carboxylic acids in reagents such as oxalyl chloride or thionyl chloride. Esters may also be prepared by reaction of the acid chloride and the hydroxy group with silver cyanide (AgCN) in an aprotic solvent such as HMPA. C1 sulfonate derivatives are prepared in a similar manner by reaction with sulfonyl chlorides.

C1 carbonate and carbamate derivatives are prepared by first reacting the C4 alcohol derivative with carbonyldiimidazole (CDI) to obtain the imidazolecarbonyl intermediate which is then reacted with an alcohol (R 4′ OH) or amine (R 4′ R 4″ NH) to give the corresponding carbonate or carbamate derivatives. In an alternate approach, reaction of the hydroxy group with 4-nitrochloroformate provides the 4-nitrophenylcarbonate which then can be reacted with amines to give carbamates or with alcohols to give carbonate derivatives. Carbamate derivatives are also prepared with commercially available carbamoyl chlorides or isocyanates.

C1 ether derivatives can also be prepared. A particulary useful procedure involves reacting an alcohol with trifluoromethane sulfonic anhydride (Tf 2 O, triflic anhydride) in dichloromethane at reduced temperature, preferably −78° C. to obtain the preformed triflate. To this solution is added the alcohol, the reaction mixture is warmed to room temperature and stirring is continued until reaction is complete. Ethers may also be prepared by heating a mixture of alcohol, the appropriate alkylhalide and an excess of silver oxide (Ag 2 O) in an aprotic invert solvent such as THF. A particularly mild method of etherification is the acid-catalyzed reaction of 2,2,2-trichloroacetimidates with alcohols. (see Goulet et al., Bioorg. & Med. Chem. Letts, 4, 921-926, 1994 and references cited therein.)

Reaction Scheme E depicts a third method of preparing compounds claimed in this invention. The amino group of the aminoalcohol derivative (Reaction Scheme C) is selectively protected with di-tert-butyl dicarbonate, a standard protecting group for amines. The beta hydroxy group can be inverted (Reaction Scheme C), and then either alcohol is derivatized according to procedures described in Reaction Scheme D. Finally, the Boc group is removed under mildly acidic conditions such as trifluoroacetic acid, and the amine is acylated by procedures described in Reaction Scheme A.

In Reaction Scheme F, the hydroxy group is converted to the corresponding amino group by well-known procedures. The hydroxy group is first derivatized as the methanesulfonate with methanesulfonyl chloride in pyridine or in THF or dichloromethane with triethylamine or pyridine. This intermediate is then reacted with sodium azide in a polar aprotic solvent such as dimethylformamide at 100° C. Alternatively, lithium azide in THF can be used. The azide displacement occurs with inversion, so that the beta hydroxy group gives the alpha azide derivative and vice versa. Finally, the azide is reduced to the corresponding amino group by hydrogenation using a palladium catalyst. This and other procedures are described in March, J.; Advanced Organic Chemistry, 4th ed., John Wiley & Sons, New York, pp. 428 and 1219 (1992).

As depicted in Reaction Scheme G, amides at C1 can be prepared by reaction of an acid chloride with the C1 amino group in a basic solvent such as pyridine. The acid chlorides, when not purchased, are prepared by stirring the carboxylic acids in reagents such as oxalyl chloride or thionyl chloride. Amides may also be prepared from carboxylic acids by using coupling reagents such as dicyclohexyl carbodiimide as reviewed by Bodanski, The Practive of Peptide Synthesis, Springer, New York, (1984). C1 sulfonamide derivatives are prepared in a similar manner by reaction with sulfonyl chlorides.

C1 urea derivatives are prepared by first reacting the C4 amino derivative with carbonyldiimidazole (CDI) to obtain the imidazolecarbonyl intermediate which is then reacted with an amine (R 4′ R 4″ NH) to give the corresponding urea derivatives. In an alternate approach, reaction of the amino group with 4-nitrochloroformate provides the 4-nitrophenylcarbamate which then can be reacted with amines to give urea derivatives. Urea derivatives are also prepared with commercially available carbamoyl chlorides or isocyanates.

C1 carbamate derivatives are prepared in a similar manner. Reacting the C4 amino derivative with carbonyldiimidazole (CDI) gives the imidazolecarbonyl intermediate which is then reacted with an alcohol to give the corresponding carbamate derivatives. In an alternate approach, reaction of the amino group with 4-nitrochloroformate provides the 4-nitrophenylcarbamate which then can be reacted with alcohols. Carbamate derivatives are also prepared with chloroformates. For instance, reaction with ethylchlorofornate will give the ethylcarbamate derivative.

The C1 amino group can be alkylated by reductive amination procedures. For instance, the C1 amino group is reacted with an aldehyde or ketone in the presence of sodium cyanoborohydride or sodium triacetoxyborohydride. This transformation may also be accomplished with hydrogen and a catalyst.

The C1 ketone can also be transformed to olefins by a variety of olefination procedures. Alkyl or arylalkyl olefins can be prepared by the Wittig-type olefination using phosphorus ylides as described by Wittig, Chem. Ber., 87, 1318 (1954). Olefins containing electron-withdrawing groups such as esters are prepared by a modification of the Wittig reagent using phosphonate reagents as depicted above. These transformations, commonly known as the Horner-Emmons, Wadsworth-Emmons or Wittig-Horner reactions, are reviewed in March, J.; Advanced Organic Chemistry, 4th ed., John Wiley & Sons, New York, pp. 956-965 (1992). Olefin products containing esters as depicted above can be further modified by procedures known to the practitioner. The double bond can be reduced by hydrogenation utilizing a catalyst such as palladium on carbon to afford a mixture of isomers at C1. Derivaitves containing an ester group can be hydrolyzed to the corresponding carboxylic acid and further modified by well-known chemical methods. Alternatively, an ester group can be reduced to an hydroxy group by various procedures. The hydroxy group can be derivatized by procedures described in Reaction Scheme D.

In Reaction Scheme I, alkyl metal, substituted alkylmetal or Grignard reagents will react with the C1 ketone to give the C1-substituted hydroxy derivatives. Cyanohydrins can be prepared using HCN gas, or indirectly utilizing trimethylsilylcyanide and a Lewis acid followed by hydrolysis. The hydroxy group can be further derivatized according to procedures described in Reaction Scheme D. In a modification of this procedure, reaction with trimethylsilylcyanide in methanol and ammonia gives the cyanoamine derivative. The amino group can be derivatized according to procedures described in Reaction Scheme G.

In Reaction Scheme J, the C1 exocyclic olefin derivative (Reaction Scheme H) can be hydroborated to give the C1 hydroxymethyl derivative. For optimal regioselectivity, a substituted borane reagent such as 9-borabicyclo(3.3.1)nonane (9-BBN) is preferred. Cleavage of the borane intermediate with hydrogen peroxide provides the hydroxymethyl product which can be derivatized by procedures described in Reaction Scheme D. Alternatively, it can be oxidized to a carboxylic acid and further modified by well-known chemical methods.

The C1 olefin can be bis-hydroxylated using osmium tetroxide either in stoichiometric amounts or catalytically with N-methyl morpholine-N-oxide. The primary hydroxy group can be selectively derivatized according to procedures described in Reaction Scheme D. The C1 hydroxy group of this bis-hydroxy compound can be dehydrated in a 2-step sequence. The primary hydroxy group is protected by acylation with acetic anhydride in pyridine. Treatment with thionyl chloride in pyridine leads to the depicted dehydro derivative. Finally, the acetate group can be removed under a variety of mild hydrolysis conditions. Reaction with potassium carbonate in methanol is effective.

As depicted in Reaction Scheme K, the C1 hydroxy group is reacted with methanesulfonyl chloride to give the reactive methane sulfonate ester (Reaction Scheme F), which is dehydrated with sodium iodide at elevated temperatures. Epoxidation with metachloroperoxy benzoic acid gives a mixture of epoxides (alpha and beta). Reduction of the epoxide with sodium borohydride gives the transposed hydroxy derivatives. The hydroxy derivatives (alpha and beta) are then oxidized to the corresponding ketone. Pyridinium chlorochromate (PCC) is particularly effective in this transformation. The transposed hydroxy derivatives and corresponding ketone can be derivatized by procedures described in the preceeding reaction schemes.

ASSAYS

T CELL IL-2 ASSAY

Peripheral blood mononuclear (MNC) cells from healthy donors were separated by density centrifugation with ficoll-hypaque (LSM, Organon Teknika, Durham, N.C.), followed by rosetted with neuraminidase treated sheep red blood cells (SRBC). After another centrifugation with leucocyte separation medium (LSM), the SRBC of the rosetted T cells were then lysed with ammonium chloride lysing buffer (GIBCO, Grand Island, N.Y.). Such purified T cells were resuspended at 3×10 6 /mL in RPMI 1640 culture medium (GIBCO) supplemented with 10% fetal calf serum (Sigma, St. Louis, Mo.), 100 mM glutamine, 1 mM sodium pyruvate, 0.1 mM non-essential amino acids, and 1% penn-strep (GIBCO). The cell suspension was immediately distributed into 96 well round-bottom microculture plates (Costar) at 200 μL/well. The various dilutions of test compound were then added in triplicate wells at 25 μL/well, incubated for 30 min at 37° C. lonomycin (125 ng/mL), and PMA (1 or 5 ng/mL), were added to the appropriate wells. The culture plates were then incubated at 37° C. in a humidified atmosphere of 5% CO 2 -95% air for 18-24 hours. The supernatants were removed, and assayed for IL-2 with an IL-2 capture ELISA, using monoclonal anti-IL-2, and biotinylated goat anti-IL-2 antibodies (unconjugated antibodies purchased from R&D System, Minneapolis, Minn.). The ELISA was developed with streptavidin conjugated peroxidase (Zymed, San Francisco, Calif.) and substrate for peroxidase (Sigma). Mean OD and units of IL-2 of the replicate wells were calculated from standard curve, created with recombinant IL-2 (Collaborative Biomedical Products, Bedford, Mass.) and the results were expressed as concentration of compound required to inhibit IL-2 production of T cells by 50%.

T CELL PROLIFERATION ASSAY

Peripheral blood mononuclear cells (MNC) from healthy donors were separated by density centrifugation with ficoll-hypaque (LSM, Organon Teknika, Durham, N.C.). After washing the MNC with complete media (RPMI 1640 medium with 5% fetal calf serum, 100 mM glutamine, 1 mM sodium pyruvate, 0.1 mM non-essential amino acid, and 1% penn-strep, obtained from GIBCO, Grand Island, N.Y.), they were then irradiated at 7500 RADS, and resuspended at 4-4.5×10 6 cells/mL in complete media. Another aliquot of MNC were rosetted with neuraminidase treated SRBC. After another centrifugation with LSM, the sheep red blood cells (SRBC) of these rosetted T cells were then lysed with ammonium chloride lysing buffer (GIBCO, Grand Island, N.Y.). After washing 2× with complete media, these purified T cells were also resuspended at 2-2.5×10 6 cells/mL in complete media. The various dilutions of the compound were added in triplicates at 50 ul/well of a 96 well flat-bottom microculture plate (Costar, Cambridge, Mass.). T cell suspension was then immediately distributed into the wells at 100 ul/well. After incubating the cells with compound for 30 min. at 37° C. in a humidified atmosphere of 5% CO 2 -95% air, 20 μΛ/well of anti-CD3 (Ortho Diagnostic, NJ) at final conc. of 0.3 ng/mL was added, followed by 50 μΛ of the irradiated MNC. The culture plates were then incubated at 37° C. in a humidified atmosphere of 5% CO 2 -95% air for 72 hours. The proliferation of T lymphocytes was assessed by measurement of tritiated thymidine incorporation. During the last 18-24 hrs. of culturing, the cells were pulse-labeled with 2 μCi/well of tritiated thymidine (NEN, Cambridge, Mass.). The cultures were harvested on glass fiber filters using a multiple sample harvester (MACH-II, Wallac, Gaithersburg, Md.). Radioactivity of filter discs corresponding to individual wells was measured by standard liquid scintillation counting methods (Betaplate Scint Counter, Wallac). Mean counts per minute of replicate wells were calculated and the results were expressed as concentration of compound required to inhibit tritiated thymidine uptake of T cells by 50%.

K v 1.3-RUBIDIUM EFFLUX ASSAY

CHO cells transfected with K v 1.3 channels at site densities of approximately 40,000 sites/cell are plated into 96 well culture plates and maintained in Iscove's Modified Dulbecco's Medium (IMDM, with L-Glutamine and HEPES, JRH Biosciences). Cells are incubated overnight with 86 Rb + (3 μCi/mL, Dupont-NEN) in the glutamine supplemented IMDM. After aspiration of the media, 100 μL of Low K Buffer (in mM, 6.5 KCl, 125 NaCl, 1 CaCl 2 , 2 MgCl 2 , 10 HEPES, pH adjusted to 7.2 with NaOH) is added to each well followed by 100 μL test samples in Low K Buffer also containing 0.2% BSA and 2 mM ouabain. Samples are tested at either 1 μg/mL for routine screening or at a variety of concentrations encompassing at least {fraction (1/10)} to 10 times the putative IC 50 of test compound to determine potency. After a fixed preincubation time, which is usually 10 min, the samples are aspirated. The K v 1.3 channels are opened by depolarization of the cells with High K Buffer (final concentrations, in mM, 63.25 KCl, 68.25 NaCl, 1 CaCl 2 , 2 MgCl 2 , 10 HEPES, pH adjusted to 7.2 with NaOH) also containing test compounds. To measure 86 Rb + efflux through the channels, aliquots of 100 μL are taken from each well after a given time and added to plates containing 100 μL MicroScint-40 (Packard) for counting by liquid scintillation techniques. MicroScint-40 (100 μL) is then added to each well of the cell plate to determine the remaining 86 Rb + activity. The efflux counts are normalized for the total amount of 86 Rb + that was in the cells by adding the efflux counts to the cell plate counts. Activity is determined by % inhibition of the efflux window that is established using a saturating concentration of margatoxin (MgTX), a 39 amino acid peptide that is a potent blocker of K v 1.3 channels (IC 50 =100 pM).

K v 1.5-RUBIDIUM EFFLUX ASSAY

The Kv1.5 86 Rb + (a potassium ion surrogate) efflux assay utilizes HEK 293 cells engineered to stably express the human Kv1.5 potassium channel. Cells are seeded at a density of 25000 cells/well in poly-D-lysine coated 96-well Packard CulturPlates one to three days prior to the assay and loaded with 86 Rb + (0.05 microcuries/well) the day before assay. On the day of assay, plates are washed three times using a Skatron 96-well plate washer and two hundred microliters of low KCl buffer (125 mM NaCl, 6.5 mM KCl, 1 mM CaCl 2 , 2 mM MgCl 2 , 0.02% bovine serum albumin, 10 mM HEPES, pH 7.2) with or without inhibitor is added to each well. After ten minutes at room temperature, the plates are washed one time with low KCl buffer and two hundred microliters of high KCl buffer (same as low KCl buffer except KCl is 60 mM and NaCl is 65 mM) with or without inhibitor is added to the appropriate wells to activate the Kv1.5 channel. The plates are incubated for an additional ten minutes at room temperature at which time one hundred microliters of each supernatant is transferred to a 96-well Packard OptiPlate. The cell plates are immediately washed one time with low KCl buffer followed by the addition of one hundred microliters of low KCl buffer to each well. One hundred microliters of Microscint scintillation cocktail is added to each well of the supematant and cell plates and radioactivity is determined on a Packard TopCount scintillation counter. The reduction of supernatant 86 Rb + is used to quantitate the degree of inhibition of the Kv1.5 potassium channel.

Di-TRITIUM CORREOLIDE (DiTC) BINDING ASSAY

Activity of compounds can be evaluated by determining their effect on DiTC binding to either Kv1.3 or Kv1.5 channels expressed in human embryonic kidney cells (HEK). The Kv1.3 and Kv1.5 channels used are cloned human channels. DiTC is also known as L-765,910 and is a natural product analogue which binds specifically to Kv1.x channels, such as Kv1.3 and Kv1.5. In general, compounds are incubated at given concentrations in the presence of 20 nM DiTC (10 μM cold ligand is used to define non-specific binding) and either HEK/K v 1.3 or HEK/Kv1.5 membranes, in a buffer containing 135 mM NaCl, 4.6 mM KCl, 20 mM Tris, pH=7.4 (tris[hydroxymethyl]aminomethane), and 0.02% bovine serum albumin (BSA). Binding is allowed to reach equilibrium by incubation of the samples at room temperature for 24 hrs. Separation of bound from free ligand is achieved by filtration through GF/C filters and washing with ice-cold buffer containing 100 mM NaCl, 20 mM Tris (pH=7.4), and 0.04% BSA. Scintilltion fluid is added to the samples and radioactivity associated with filters determined by liquid scintillation techniques. Specific DiTC binding is the difference between total and non-specific binding. The activity of a given compound is assessed relative to an untreated control.

HEK cells expressing either human Kv1.3 or Kv1.5 channels were grown by Analytical Biological Services in bioreactors containing MEM supplemented with FBS, Penicillin, Streptomycin, and Geneticin. Seven tubes of frozen cell pellets (25 L of cells) were then thawed and 20 mL Homogenization Buffer was added to each tube. The contents of the tubes were pooled into a 50 mL glass/Teflon homogenizer. The cells were homogenized for 10 strokes (500 rpm) and transferred to 50 mL tubes. The tubes were then centrifuged at 1000 rpm for 5 min at 4° C. (253×g, Beckman GPR). The supernatant was collected and set aside on ice. The pellets were resuspended in a total of 40 mL Lysis Buffer, homogenized as described above, and the homogenate was centrifuged as described above. The supernatant was added to the set aside supernatant. The pooled supernatant was then centrifuged at 40,000 rpm for 45 min at 4° C. (186,000×g, Beckman 45TI). The pellet was resuspended in 70 mL Storage Buffer by homogenization as described above. Aliquots were flash frozen using liquid nitrogen and stored at −70° C. (Homogenization Buffer: 250 mM Sucrose, 5 mM MgCl 2 , 20 mM Tris, pH=7.4; Storage Buffer: 100 mM NaCl, 20 mM HEPES, pH=7.4).

The compounds of this invention can be administered for the treatment of autoimmune diseases, the prevention of rejection of foreign organ transplants and/or related afflictions, diseases and illnesses according to the invention by any means that effects contact of the active ingredient compound with the site of action in the body of a warm-blooded animal. For example, administration, can be oral, topical, including transdermal, ocular, buccal, intranasal, inhalation, intravaginal, rectal, intracisternal and parenteral. The term “parenteral” as used herein refers to modes of administration which include subcutaneous, intravenous, intramuscular, intraarticular injection or infusion, intrastemal and intraperitoneal.

The compounds can be administered by any conventional means available for use in conjunction with pharmaceuticals, either as individual therapeutic agents or in a combination of therapeutic agents. They can be administered alone, but are generally administered with a pharmaceutical carrier selected on the basis of the chosen route of administration and standard pharmaceutical practice.

For the purpose of this disclosure, a warm-blooded animal is a member of the animal kingdom possessed of a homeostatic mechanism and includes mammals and birds.

The dosage administered will be dependent on the age, health and weight of the recipient, the extent of disease, kind of concurrent treatment, if any, frequency of treatment and the nature of the effect desired. Usually, a daily dosage of active ingredient compound will be from about 1-500 milligrams per day. Ordinarily, from 10 to 100 milligrams per day in one or more applications is effective to obtain desired results. These dosages are the effective amounts for the treatment of autoimmune diseases, the prevention of rejection of foreign organ transplants and/or related afflictions, diseases and illnesses.

The active ingredient can be administered orally in solid dosage forms, such as capsules, tablets, troches, dragees, granules and powders, or in liquid dosage forms, such as elixirs, syrups, emulsions, dispersions, and suspensions. The active ingredient can also be administered parenterally, in sterile liquid dosage forms, such as dispersions, suspensions or solutions. Other dosages forms that can also be used to administer the active ingredient as an ointment, cream, drops, transdermal patch or powder for topical administration, as an ophthalmic solution or suspension formation, i.e., eye drops, for ocular administration, as an aerosol spray or powder composition for inhalation or intranasal administration, or as a cream, ointment, spray or suppository for rectal or vaginal administration.

Gelatin capsules contain the active ingredient and powdered carriers, such as lactose, starch, cellulose derivatives, magnesium stearate, stearic acid, and the like. Similar diluents can be used to make compressed tablets. Both tablets and capsules can be manufactured as sustained release products to provide for continuous release of medication over a period of hours. Compressed tablets can be sugar coated or film coated to mask any unpleasant taste and protect the tablet from the atmosphere, or enteric coated for selective disintegration in the gastrointestinal tract.

Liquid dosage forms for oral administration can contain coloring and flavoring to increase patient acceptance.

In general, water, a suitable oil, saline, aqueous dextrose (glucose), and related sugar solutions and glycols such as propylene glycol or polyethylene gycols are suitable carriers for parenteral solutions. Solutions for parenteral administration preferably contain a water soluble salt of the active ingredient, suitable stabilizing agents, and if necessary, buffer substances. Antioxidizing agents such as sodium bisulfite, sodium sulfite, or ascorbic acid, either alone or combined, are suitable stabilizing agents. Also used are citric acid and its salts and sodium EDTA. In addition, parenteral solutions can contain preservatives, such as benzalkonium chloride, methyl- or propylparaben, and chlorobutanol.

Suitable pharmaceutical carriers are described in Remington's Pharmaceutical Sciences , A. Osol, a standard reference text in this field.

For administration by inhalation, the compounds of the present invention may be conveniently delivered in the form of an aerosol spray presentation from pressurized packs or nebulisers. The compounds may also be delivered as powders which may be formulated and the powder composition may be inhaled with the aid of an insufflation powder inhaler device. The preferred delivery system for inhalation is a metered dose inhalation (MDI) aerosol, which may be formulated as a suspension or solution of a compound of Formula I in suitable propellants, such as fluorocarbons or hydrocarbons.

For ocular administration, an ophthalmic preparation may be formulated with an appropriate weight percent solution or suspension of the compounds of Formula I in an appropriate ophthalmic vehicle, such that the compound is maintained in contact with the ocular surface for a sufficient time period to allow the compound to penetrate the corneal and internal regions of the eye.

Useful pharmaceutical dosage-forms for administration of the compounds of this invention can be illustrated as follows:

CAPSULES

A large number of unit capsules are prepared by filling standard two-piece hard gelatin capsules each with 100 milligrams of powdered active ingredient, 150 milligrams of lactose, 50 milligrams of cellulose, and 6 milligrams magnesium stearate.

SOFT GELATIN CAPSULES

A mixture of active ingredient in a digestible oil such as soybean oil, cottonseed oil or olive oil is prepared and injected by means of a positive displacement pump into gelatin to form soft gelatin capsules containing 100 milligrams of the active ingredient. The capsules' are washed and dried.

TABLETS

A large number of tablets are prepared by conventional procedures so that the dosage unit is 100 milligrams of active ingredient, 0.2 milligrams of colloidal silicon dioxide, 5 milligrams of magnesium stearate, 275 milligrams of microcrystalline cellulose, 11 milligrams of starch and 98.8 milligrams of lactose. Appropriate coatings may be applied to increase palatability or delay absorption.

INJECTABLE

A parenteral composition suitable for administration by injection is prepared by stirring 1.5% by weight of active ingredient in 10% by volume propylene glycol. The solution is made to volume with water for injection and sterilized.

SUSPENSION

An aqueous suspension is prepared for oral administration so that each 5 milliliters contain 100 milligrams of finely divided active ingredient, 100 milligrams of sodium carboxymethyl cellulose, 5 milligrams of sodium benzoate, 1.0 grams of sorbitol solution, U.S.P., and 0.025 milliliters of vanillin.

The same dosage forms can generally be used when the compounds of this invention are administered stepwise or in conjunction with another therapeutic agent. When drugs are administered in physical combination, the dosage form and administration route should be selected depending on the compatibility of the combined drugs. Thus the term coadministration is understood to include the administration of the two agents concomitantly or sequentially, or alternatively as a fixed dose combination of the two active components.

The following examples illustrate the preparation of the compounds of Formula I and as such are not to be considered as limiting the invention set forth in the claims appended hereto.
