Full Description:
BACKGROUND OF THE INVENTION  
         [0001]    The neurokinins are a family of mammalian neuropeptides that are involved with numerous biological activities such as pain transmission, vasodilation, smooth muscle contraction, bronchoconstriction, activation of the immune system, and neurogenic inflammation. One such neuropeptide known as substance P is widely distributed throughout the peripheral and central nervous system of mammals, and is known to mediate a variety of biological actions via interaction with three neurokinin (NK or tachykinin) receptor types known as NK 1 , NK 2 , and NK 3 .  
           [0002]    Substance P binds with higher affinity to the NK 1  receptor than it does to the other receptors. Accordingly, compounds capable of antagonizing the effects of substance P at the NK 1  receptor are useful for treating and controlling disorders mediated by such interactions, including disorders such as anxiety, pain, depression, schizophrenia, and emesis.  
           [0003]    Since 1991, a number of high-affinity nonpeptide tachykinin antagonists have been reported; for a review see Sprecher A, et al ( IDrugs,  1:73-91, 1998).  
           [0004]    U.S. Pat. Nos. 5,594,022 and 5,716,979 describe nonpeptides that are relatively specific NK 1  antagonists.  
           [0005]    Since substance P mediate various biological actions, including smooth muscle contraction, pain transmission, neuronal excitation, secretion of saliva, angiogenesis, broncho-constriction, activation of the immune system and neurogenic inflammation via an interaction with NK receptors, preferably NK 1 , thus compounds capable of antagonising the effects of substance P at NK 1  receptors will be useful in treating or preventing a variety of: brain disorders including pain (inflammatory, surgical and neuropathic), anxiety, panic, depression, schizophrenia, neuralgia, stress, sexual dysfunction, bipolar disorders, movement disorders, cognitive disorders, obesity and addiction disorders; inflammatory diseases such as arthritis, asthma, bronchitis and psoriasis; gastrointestinal disorders including colitis, Crohn&#39;s disease, irritable bowel syndrome, and satiety; allergic responses such as eczema and rhinitis; vascular disorders such as angina and migraine; neuropathological disorders including scleroderma and emesis.  
           [0006]    The compounds of the invention, NK 1  receptor antagonists, are useful as anti-angiogenic agents for the treatment of conditions associated with aberrant neovascularization such as rheumatoid arthritis, atherosclerosis and tumour cell growth. They will also be useful as agents for imaging NK 1  receptors in vivo in conditions such as ulcerative colitis and Crohn&#39;s disease.  
         SUMMARY OF THE INVENTION  
         [0007]    This invention provides NK 1  receptor antagonists characterized as non-peptide acetamide derivatives. The compounds of the invention differ from those of U.S. Pat. Nos. 5,716,979 or 5,594,022 in that the compounds of Formula I below are not (N-substituted aryl-methyl) carbamates, i.e. they do not have a —O—C(O)—N— link in the backbone; certain final products being more stable than known compounds, they should show improved oral bioavailability and improved CNS penetration.

           [0201]    The term “alkyl” means a straight or branched hydrocarbon having from one to 12 carbon atoms and includes, for example, methyl, ethyl, n-propyl, isopropyl, n-butyl, sec-butyl, tert-butyl, n-pentyl, n-hexyl, n-heptyl, n-octyl, undecyl, dodecyl, and the like unless stated specifically otherwise.  
           [0202]    The term “cycloalkyl” means a saturated hydrocarbon ring which contains from 3 to 12 carbon atoms, for example cyclopropyl, cyclobutyl, cyclopentyl, cyclohexyl except as otherwise stated.  
           [0203]    The term “alkoxy” means an alkyl as described above attached through an oxygen atom.  
           [0204]    The term “halogen” is chlorine, bromine, fluorine or iodine.  
           [0205]    The ring formed by joining R 5  and R 6  is from 4 to 6 atoms total and is unsubstituted.  
           [0206]    The compounds of Formula I are capable of forming pharmaceutically acceptable acid addition salts. All of these forms are within the scope of the present invention.  
           [0207]    Pharmaceutically acceptable acid addition salts of the compound of Formula I include salts derived from inorganic acids such as hydrochloric, nitric, phosphoric, sulfuric, hydrobromic, hydroiodic, hydrofluoric, phosphorous, and the like as well as the salts derived from nontoxic organic acids, such as the aliphatic mono- and dicarboxylic acids, phenyl-substituted alkanoic acids, hydroxy-alkanoic acids, alkanedioic acids, aromatic acids, aliphatic and aromatic sulfonic acids, etc. Such salts thus include sulfate, pyrosulfate, bisulfate, sulfite, bisulfite, nitrate, phosphate, monohydrogenphosphate, dihydrogenphosphate, metaphosphate, pyrophosphate, chloride, bromide, iodide, fluoride, acetate, trifluoroacetate, propionate, caprylate, isobutyrate, oxalate, malonate, succinate, suberate, sebacate, fumarate, maleate, mandalate, benzoate, chlorobenzoate, methylbenzoate, dinitrobenzoate, phthalate, benzenesulfonate, toluenesulfonate, phenylacetate, citrate, lactate, tartrate, methanesulfonate, and the like. Also contemplated are salts of amino acids such as arginate and the like. For example, see Berge S. M., et al., Pharmaceutical Salts,  J. Pharm. Sci.,  66:1-19 (1977) incorporated herein by reference.  
           [0208]    The acid addition salts of the compounds of Formula I are prepared by contacting the free base form of the compound with a sufficient amount of the desired acid to produce the salt in the conventional manner. Preferably, a compound of Formula I can be converted to an acidic salt by treating an aqueous solution of the desired acid, such that the resulting pH is less than four. The solution can be passed through a C18 cartridge to absorb the compound, washed with copious amounts of water, the compound eluted with a polar organic solvent such as, for example methanol, acetonitrile, aqueous mixtures thereof, and the like, and isolated by concentrating under reduced pressure followed by lyophilisation. The free base form may be regenerated by contacting the salt form with a base and isolating the free base in the conventional manner. The free base forms differ from their respective salt forms somewhat in certain physical properties such as solubility in polar solvents, but otherwise the salts are equivalent to their respective free base for the purpose of the present invention.  
           [0209]    Certain of the compounds of the present invention can exist in unsolvated forms as well as solvated forms, including hydrated forms. In general, the solvated forms, including hydrated forms are equivalent to unsolvated forms and are intended to be encompassed within the scope of the present invention.  
           [0210]    Certain of the compounds of the present invention possess one or more chiral centers and each center may exist in the R( D ) or S( L ) configuration. The present invention includes all enantiomeric and epimeric forms as well as the appropriate mixtures thereof  
           [0211]    The compounds of the present invention can be prepared and administered in a wide variety of oral and parenteral dosage forms. Thus, the compounds of the present invention can be administered by injection, that is intravenously, intramuscularly, intracutaneously, subcutaneously, intraduodenally, or intraperitoneally. In addition, the compounds of the present invention can be administered by inhalation, for example intranasally. Additionally, the compounds of the present invention can be administered transdermally. It will be obvious to those skilled in the art that the following dosage forms may comprise as the active component, either a compound of Formula I or a corresponding pharmaceutically acceptable salt of the compound of Formula I.  
           [0212]    For preparing pharmaceutical compositions from the compounds of the present invention, pharmaceutically acceptable carriers can be either solid or liquid. Solid form preparations include powders, pills, tablets, capsules, cachets, suppositories and dispersible granules. A solid carrier can be one or more substances that may also act as diluents, flavouring agents, binders, preservatives, tablet disintegrating agents, or an encapsulating material.  
           [0213]    In powders, the carrier is a finely divided solid that is in a mixture with the finely divided active component.  
           [0214]    In tablets, the active component is mixed with the carrier having the necessary binding properties in suitable proportions and compacted in the shape and size desired.  
           [0215]    The powders and tablets preferably contain from 5% or 10% to about 70% of the active compound. Suitable carriers are magnesium carbonate, magnesium stearate, talc, sugar, lactose, pectin, dextrin, starch, gelatin, tragacanth, methylcellulose, sodium carboxymethylcellulose, a low melting wax, cocoa butter, and the like. The term “preparation” is intended to include the formulation of the active compound with encapsulating material as a carrier providing a capsule in which the active component with or without other carriers, is surrounded by a carrier, which is thus in association with it. Similarly, cachets and lozenges are included. Tablets, powders, capsules, pills, cachets, and lozenges can be used as solid dosage forms suitable for oral administration.  
           [0216]    For preparing suppositories, a low melting wax such as a mixture of fatty acid glycerides or cocoa butter, is first melted and the active component is dispersed homogeneously therein, as by stirring. The molten homogeneous mixture is then poured into convenient sized moulds, allowed to cool, and thereby to solidify.  
           [0217]    Liquid form preparations include solutions, suspensions and emulsions, for example, water or water propylene glycol solutions. For parenteral injection, liquid preparations can be formulated in solution in aqueous polyethylene glycol solution.  
           [0218]    Aqueous solutions suitable for oral use can be prepared by dissolving the active component in water and adding suitable colorants, flavours, stabilizing and thickening agents as desired.  
           [0219]    Aqueous suspensions suitable for oral use can be made by dispersing the finely divided active component in water with viscous material, such as natural or synthetic gums, resins, methylcellulose sodium carboxymethylcellulose, and other well-known suspending agents.  
           [0220]    Also included are solid form preparations that are intended to be converted, shortly before use, to liquid form preparations for oral administration. Such liquid forms include solutions, suspensions, and emulsions. These preparations may contain, in addition to the active component, colorants, flavours, stabilizers, buffers, artificial and natural sweeteners, dispersants, thickeners, solubilising agents and the like.  
           [0221]    The pharmaceutical preparation is preferably in unit dosage form. In such form, the preparation is subdivided into unit doses containing appropriate quantities of the active component. The unit dosage form can be a packaged preparation, the package containing discrete quantities of preparation, such as packeted tablets, capsules, and powders in vials or ampoules. Also, the unit dosage form can be a capsule, tablet, cachet or lozenge itself, or it can be the appropriate number of any of these in packaged form.  
           [0222]    The quantity of active component in a unit dose preparation may be varied or adjusted from 0.1 mg to 200 mg, preferably 0.5 mg to 100 mg according to the particular application and the potency of the active component. The composition can, if desired, also contain other compatible therapeutic agents.  
           [0223]    In therapeutic use, the highly selective and competitive antagonists of the NK 1  receptor and compounds utilized in the pharmaceutical method of this invention are administered at the initial dosage of about 0.01 mg/kg to about 500 mg/kg daily. A daily dose range of about 0.01 mg/kg to about 100 mg/kg is preferred. The dosages, however, may be varied depending upon the requirements of the patient, the severity of the condition being treated and the compound being employed. Determination of the proper dosage for a particular situation is within the skill of the art. Generally, treatment is initiated with smaller doses, which are less than the optimum dose of the compound. Thereafter, the dosage is increased by small increments until the optimum effect under the circumstances is reached. For convenience, the total daily dosage may be divided and administered in portions during the day, if desired.  
           [0224]    The compounds of Formula I can be prepared by any several synthetic processes well known to those skilled in the art of organic chemistry.  
                         
 
           [0225]    In a typical synthesis, a carboxylic acid of the formula  
           [0226]    is coupled to an amine of the formula  
                         
 
           [0227]    The coupling can be achieved by routine acylation, e.g. by converting the acid to an acid halide, followed by reaction with the amine, or by utilizing a common coupling reagent such as 1,3 -dicyclohexylcarbodiimide (DCC) or 2-ethoxy-1-ethoxycarbonyl-1,2-dihydroquinoline (EEDQ). The synthesis can be carried out on racemic reactants, to provide invention compounds in racemic form, which can then be resolved by conventional methods, if desired. Alternatively, the invention compounds can be prepared in optically active form by using enantiomeric reactants.  
           [0228]    In a typical synthesis, an optically active acetic acid is first prepared by conventional methods. Schemes 1-5 illustrate the preparation of intermediates utilized in Examples 1-5, which illustrate the synthesis of specific compounds of Formula I in optically active form. Scheme 1 describes the synthesis of intermediates I and II, which are required for Examples 1 to 5. The N-terminal benzofuran moiety is introduced by the reductive amination of either tryptophan methyl ester or alpha-methyl-tryptophan methyl ester with benzofuran-2-carboxaldehyde and sodium triacetoxy borohydride in DCM. The methyl ester is then hydrolyzed to the corresponding carboxylic acid with lithium hydroxide.  
           [0229]    Scheme 2 describes the synthesis of intermediate III. 3-Acetyl-l-methyl pyrrole is converted to the corresponding oxime by reaction with hydroxylamine sulfate and potassium hydroxide in water/methanol. The oxime is then reduced on palladium on carbon.  
           [0230]    Scheme 3 shows the synthesis of intermediate IV. This compound was prepared from (R)-2-phenylglycinol, which was first N-terminal protected as the carbobenzoxy (CBZ) analogue. The alcohol was then treated with triethylamine and methane sulfonylchloride, followed by dimethylamine to introduce the tertiary amine. Removal of the CBZ protection with hydrogen over Pearlman&#39;s catalyst gave the required intermediate.  
           [0231]    Scheme 4 describes the synthesis of Examples 1 to 4. Each was prepared by activation of the acid, intermediate I, with HBTU in the presence of DIPEA and then reacting with the required amine in DMF.  
           [0232]    The synthesis of Example 5 is outlined in scheme 5. Intermediate I was activated with HBTU in DMF and then coupled with methoxybenzylamine. The methyl ether was then reduced with boron tribromide in DCM.

         [0325]    A 40-well DTI synthesizer rack (U.S. Pat. No. 5,324,483) was loaded with 40 DTI vials (12 mL). To each vial 0.15-0.21 mmol of an amine or amine HCl salt was added. The rack was placed in a Cyberlab Liquid Handling Robot and to each vial 0.10 mmol N-[b]benzofuranylmethyl-R-α-methyl-tryptophan-N-carboxyanhydride (0.227 M in THF) was added. To those vials that contained amine HCl salts, 0.15 mmol triethylamine (0.254 M in THF) was added, in order to liberate the free amines. THF was then added to each vial to make up the total volume to 3 mL. The vials were placed in a 40-well DTI synthesizer equipped with a heating block, 40 condensers and a nitrogen manifold. The synthesizer was kept under a continuous flow of nitrogen and was shaken at 65° C. on an orbital shaker for 2 days. The reactions were monitored by TLC (10% CH 3 CN in CH 2 Cl 2 ). The vials in which the reaction had gone to completion were taken out. To the remaining vials CH 3 CN (2 mL) was added each and these were shaken at 85° C. for 19 h. The vials in which the reaction had gone to completion were taken out. To the remaining vials pyridine (1 mL) was added each and these were shaken at 105° C. for 6 h followed by 15 h at 65° C. The vials were then concentrated at reduced pressure in a Speedvac and were purified by chromatography over a 12 mL LC-Si SPE cartridge containing 2 g silica (elution with 10% CH 3 CN in CH 2 Cl 2  followed by 20% CH 3 CN in CH 2 Cl 2 , 5% methanol in CH 2 Cl 2 , 10% methanol in CH 2 Cl 2 , 20% methanol in CH 2 Cl 2  and 50% methanol in CH 2 Cl 2 , depending on the polarity of the products). The products were subjected to LC-MS. Those products which did contain the desired molecular ion, but were not sufficiently pure (typically&lt;85%) were further purified by prep HPLC on a C18 reversed phase preparative column. The HPLC-purified products were re-analyzed by LC-MS to determine the purity. The 40 final products were analyzed by  1 H NMR.

To each vial approximately 0.34 g (0.10 mmol) N-[b]benzofuranylmethyl-R-tryptophan was added followed by 1.5 equivalent of an amine or amine HCl salt. The rack was placed in a Cyberlab Liquid Handling Robot and to each vial 1.0 equivalent of HBTU (0.4 M in DMF) was added followed by 1.5 equivalent of diisopropylethylamine (0.5 M in DMF). To those vials, which contained amine HCl salts, an additional equivalent of diisopropylethylamine was added. DMF was added to make the total volume up to 1.5 mL. The vials were capped and the rack was shaken on an orbital shaker at room temperature for 3 h. To each vial, water (1 mL) was added and the mixtures were purified on 3 mL LC-18 reversed phase SPE cartridges containing 500 mg of sorbent, using an ASPEC XL4 robot. The cartridges were conditioned with methanol (4 mL) followed by methanol/water 1:1 (4 mL). Water (1 mL) was loaded onto the cartridges and the crude reaction mixtures were loaded into the water layer. The cartridges were washed with water (4 mL) and methanol/water 1:1 (4 mL) and were eluted with methanol (4 mL). The methanol fractions were concentrated and the products were subjected to LC-MS. Those products which did contain the desired molecular ion, but were not sufficiently pure (typically&lt;90%) were further purified by prep HPLC on a C18 reversed phase preparative column.

         [0337]    Because the compounds are potent ligands to the NK 1  receptor, they are effective at displacing substance P at that position, and therefore are useful for treating biological conditions otherwise mediated by substance P. Accordingly, compounds capable of antagonising the effects of substance P at NK 1  receptors will be useful in treating or preventing a variety of brain disorders including pain (inflammatory, surgical and neuropathic), anxiety, panic, depression, schizophrenia, neuralgia, stress, sexual dysfunction, bipolar disorders, movement disorders, cognitive disorders, and addiction disorders; inflammatory diseases such as arthritis, asthma, and psoriasis; gastrointestinal disorders including colitis, Crohn&#39;s disease, irritable bowel syndrome and satiety; allergic responses such as eczema and rhinitis; vascular disorders such as angina and migraine; neuropathological disorders including scleroderma and emesis. The compounds of the invention, NK 1  receptor antagonists, are also useful as anti-angiogenic agents, for the treatment of conditions associated with aberrant neovascularization such as rheumatoid arthritis, atherosclerosis and tumour cell growth. They will also be useful as agents for imaging NK 1  receptors in vivo in conditions such as ulcerative colitis and Crohn&#39;s disease.  
         [0338]    The compounds of the present invention are highly selective and competitive antagonists of the NK 1  receptor. They have been evaluated in an NK 1 -receptor binding assay which is described below.  
         [0339]    Human lymphoma IM9 cells were grown in RPMI 1640 culture medium supplemented with 10% fetal calf serum and 2 mM glutamine and maintained under an atmosphere of 5% CO 2 . Cells were passaged every 3-4 days by reseeding to a concentration of 4-8×10 6 /40 ml per 175 cm 2  flask. Cells were harvested for experiments by centrifugation at 1000 g for 3 min. Pelleted cells were washed once by resuspension into assay buffer (50 mM Tris HCl pH 7.4, 3 mM MnCl 2 , 0.02% BSA, 40 mg/mL bacitracin, 2 mg/mL chymostatin, 2 mM phosphoramidon, 4 mg/mL leupeptin) and repeating the centrifugation step before resuspending at a concentration of 2.5×10 6  cells/mL assay buffer. Cells (200 ml) were incubated with [ 125 I]Bolton-Hunter substance P (0.05-0.1 nM) in the presence and absence of varying concentrations of test compounds for 50 min at 21° C. Non-specific binding (10% of the total binding observed under these conditions) was defined by 1 mM [Sar 9 , Met(0 2 ) 11 ] substance P. Reactions were terminated by rapid filtration under vacuum onto GF\C filters presoaked in 0.2% PEI for 1-2 h, using a Brandel cell harvester. Filters were washed with 6×1 ml ice-cold Tris HCl (50 mM, pH 7.4) and radioactivity bound determined using a gamma counter. Results were analyzed using iterative curve fitting procedures in RS1 or Graphpad Inplot.
