NAPHTHAMIDE NEUROKININ ANTAGONISTS FOR USE AS MEDICAMENTS

Abstract: A compound having the general formula (Ia) and methods of using such compounds for the treatment of diseases and pharmaceutical composition comprising such compounds.

Description: COMPOUNDS Background The mammalian neurokinins comprise a class of peptide neuro transmitters which are found in the peripheral and central nervous systems. The three principal neurokinins are Substance P (SP), Neurokinin A (NKA) and Neurokinin B (NKB). There are also N-terminally extended forms of at least NKA. At least three receptor types are known for the three principal neurokinins. Based upon their relative selectivities favoring the neurokinin agonists SP, NKA and NKB, the receptors are classified as neurokinin 1 (NK,), neurokinin 2 (NK 2 ) and neurokinin 3 (NK 3 ) receptors, respectively. It is now recognized that anxiety, stress, and depression are interrelated conditions (File SE Pharmacol, Biochem & Behavior 54/1:3-12, 1996). Moreover, these complex emotional states cannot be due simply to defects in a single neurotransmitter although 5-HT has been ascribed a principal role (Graeff et al., Pharmacol, Biochem & Behavior 54/1 : 129- 141, 1996). Substance P (SP) was one of the first neuropeptides to be identified in mammalian brain and it is now accepted that all three tachykinins are found within the CNS (Iversen LL J Psychopharmacol 3/1: 1-6, 1989), particularly in the striatonigral neurons, hypothalamus and limbic forebrain (ibid). NK, and NK 3 receptors have been identified in the brain as well (Beaujouan et al., Neurosci. 18: 857-875, 1986). Controversy has existed regarding the presence ofthe NK 2 receptor in brain, although recent evidence shows receptor localization in at least the septal region (Steinberg et al., Eur J Neurosci 10/7:2337-45 1998). Pharmacological evidence supporting a role for either NK, or NK 2 receptors in anxiety disorders has been accumulating from assorted animal behavioral tests (for examples, see Table 1). Animal models of depression, however, have been used rarely to define the potential utility of NK receptor antagonists. SP stimulates the turnover of other neurotransmitters involved in depression, i.e., 5-HT in the raphe nucleus, an area thought to be linked to depressive phenomena (Forchetti et al., J. Neurochem. 38: 1336-1341, 1982). When injected centrally to nuclei responsible for control of emotion and stress, SP evokes a hemodynamic pressor response bridging this peptide to stress induced hypertension (Ku et al., RepttJes; 19/4: 677-82, 1998). Moreover, rises in both heart rate and mean arterial blood pressure evoked by physical stress can be blocked in rodents by centrally administered NK, receptor antagonists (Culman et al., J Pharmacol Exp Ther 280/1:238-46, 1997).

Particular compounds of this invention are provided as the Examples hereinbelow. C γ - Z alkyl, unless otherwise specified, means an alkyl chain containing a minimum Y total carbon atoms and a maximum Z total carbon atoms. These alkyl chains may be branched or unbranched, cyclic, acyclic or a combination of cyclic and acyclic. For example, the following substituents would be included in the general description "C 4 - 7 alkyl": Pharmaceutically-acceptable salts may be prepared from the corresponding acid in conventional manner. Non-pharmaceutically-acceptable salts may be useful as intermediates and as such are another aspect ofthe present invention. The term "oxo" means a double bonded oxygen (=O). Some ofthe compounds ofthe present invention are capable of forming salts with various inorganic and organic acids and bases and such salts are also within the scope of this invention. Examples of such acid addition salts include acetate, adipate, ascorbate, benzoate, benzenesulfonate, bisulfate, butyrate, camphorate, camphorsulfonate, citrate, cyclohexyl sulfamate, ethanesulfonate, fumarate, glutamate, glycolate, hemisulfate, 2-hydroxyethyl- sulfonate, heptanoate, hexanoate, hydrochloride, hydrobromide, hydroiodide, hydroxymaleate, lactate, malate, maleate, methanesulfonate, 2-naphthalenesulfonate, nitrate, oxalate, pamoate, persulfate, phenylacetate, phosphate, picrate, pivalate, propionate, quinate, salicylate, stearate, succinate, sulfamate, sulfanilate, sulfate, tartrate, tosylate (p- toluenesulfonate), and undecanoate. Base salts include ammonium salts, alkali metal salts such as sodium, lithium and potassium salts, alkaline earth metal salts such as aluminum, calcium and magnesium salts, salts with organic bases such as dicyclohexylamine salts, N- methyl-D-glucamine, and salts with amino acids such as arginine, lysine, ornithine, and so forth. Also, basic nitrogen-containing groups may be quaternized with such agents as: lower alkyl halides, such as methyl, ethyl, propyl, and butyl halides; dialkyl sulfates like dimethyl, diethyl, dibutyl; diamyl sulfates; long chain halides such as decyl, lauryl, myristyl and stearyl halides; aralkyl halides like benzyl bromide and others. Non-toxic physiologically-acceptable salts are preferred, although other salts are also useful, such as in isolating or purifying the product. The salts may be formed by conventional means, such as by reacting the free base form ofthe product with one or more equivalents ofthe appropriate acid in a solvent or medium in which the salt is insoluble, or in a solvent such as water, which is removed in vacuo or by freeze drying or by exchanging the anions of an existing salt for another anion on a suitable ion-exchange resin. In order to use a compound ofthe formula (I) or a pharmaceutically acceptable salt thereof for the therapeutic treatment (including prophylactic treatment) of mammals including humans, it is normally formulated in accordance with standard pharmaceutical practice as a pharmaceutical composition. Therefore in another aspect the present invention provides a pharmaceutical composition which comprises a compound ofthe formula (I) or a pharmaceutically acceptable salt and pharmaceutically acceptable carrier. The pharmaceutical compositions of this invention may be administered in standard manner for the disease condition that it is desired to treat, for example by oral, topical, parenteral, buccal, nasal, vaginal or rectal adminstration or by inhalation or insufflation. For these purposes the compounds of this invention may be formulated by means known in the art into the form of, for example, tablets, capsules, aqueous or oily solutions, suspensions, emulsions, creams, ointments, gels, nasal sprays, suppositories, finely divided powders or aerosols or nebulisers for inhalation, and for parenteral use (including intravenous, intramuscular or infusion) sterile aqueous or oily solutions or suspensions or sterile emulsions. In addition to the compounds ofthe present invention the pharmaceutical composition of this invention may also contain, or be co-administered (simultaneously or sequentially) with, one or more pharmacological agents of value in treating one or more disease conditions referred to herein. The pharmaceutical compositions of this invention will normally be administered to humans so that, for example, a daily dose of 0.01 to 25 mg/kg body weight (and preferably of 0.1 to 5 mg/kg body weight) is received. This daily dose may be given in divided doses as necessary, the precise amount ofthe compound received and the route of administration depending on the weight, age and sex ofthe patient being treated and on the particular disease condition being treated according to principles known in the art. Typically unit dosage forms will contain about 1 mg to 500 mg of a compound of this invention. For example a tablet or capsule for oral administration may conveniently contain up to 250 mg (and typically 5 to 100 mg) of a compound of the formula (I) or a pharmaceutically acceptable salt thereof. In another example, for administration by inhalation, a compound ofthe formula (I) or a pharmaceutically acceptable salt thereof may be administered in a daily dosage range of 5 to 100 mg, in a single dose or divided into two to four daily doses. In a further example, for administration by intravenous or intramuscular injection or infusion, a sterile solution or suspension containing up to 10% w/w (and typically 5% w/w) of a compound ofthe formula (I) or a pharmaceutically acceptable salt thereof may be used. Therefore in a further aspect, the present invention provides a compound ofthe formula (I) or a pharmaceutically acceptable salt thereof for use in a method of therapeutic treatment ofthe human or animal body. In yet a further aspect the present invention provides a method of treating a disease condition wherein antagonism ofthe NK, receptor is beneficial which comprises administering to a warm-blooded animal an effective amount of a compound ofthe formula (I) or a pharmaceutically-acceptable salt thereof. The present invention also provides the use of a compound of the formula (I) or a pharmaceutically acceptable salt thereof in the preparation of a medicament for use in a disease condition wherein antagonism of the NK, receptor is beneficial. The compounds ofthe formula (I) and their pharmaceutically acceptable salts may be made by processes as described and exemplified herein and by processes similar thereto and by processes known in the chemical art. If not commercially available, starting materials for these processes may be made by procedures which are selected from the chemical art using techniques which are similar or analogous to the synthesis of known compounds. It is well known in the art how to prepare optically-active forms (for example, by resolution ofthe racemic form or by synthesis from optically-active starting materials) and how to determine the NK, antagonist properties by the standard tests known in the art and those described hereinafter. Some individual compounds within the scope of this invention may contain double bonds. Representations of double bonds in this invention are meant to include both the E and the Z isomer ofthe double bond. Additionally, some species within the scope of this invention may contain one or more asymmetric centers. This invention includes the use of any of the optically pure stereoisomers as well as any combination of stereoisomers. Some compounds bearing a 2-substituted naphthamide can exist as a mixture of conformational isomers (atropisomers) ("The Chemistry of Rotational Isomers"; Oki, M.; Springer Verlag, NY; 1993). Where individual atropisomers have been isolatable, distinct chemical and biological properties have been observed. The compounds of this invention comprise both mixtures of, and individual, atropisomers. The following biological test methods, data and Examples serve to illustrate and further describe the invention. The utility of a compound ofthe invention or a pharmaceutically acceptable salt thereof (hereinafter, collectively referred to as a "compound") may be demonstrated by standard tests and clinical studies, including those disclosed in the publications described below. SP Receptor Binding Assay (Test A) The ability of a compound ofthe invention to antagonize the binding of SP at the NK, receptor may be demonstrated using an assay using the human NK, receptor expressed in Mouse Erythroleukemia (MEL) cells. The human NK, receptor was isolated and characterized as described in: B. Hopkins, et al. "Isolation and characterization ofthe human lung NK, receptor cDNA" Biochem. Biophvs. Res. Comm.. 1991 , 180, 1110- 1117; and the NK, receptor was expressed in Mouse Erythroleukemia (MEL) cells using a procedure similar to that described in Test B below. Neurokinin A (NKA) Receptor Binding Assay (Test B) The ability of a compound ofthe invention to antagonize the binding of NKA at the NK 2 receptor may be demonstrated using an assay using the human NK 2 receptor expressed in Mouse Erythroleukemia (MEL) cells, as described in: Aharony, D., et al. "Isolation and Pharmacological Characterization of a Hampster Neurokinin A Receptor cDNA" Molecular Pharmacology. 1994, 45., 9-19. The selectivity of a compound for binding at the NK, and the NK 2 receptors may be shown by determining its binding at other receptors using standard assays, for example, one using a tritiated derivative of NKB in a tissue preparation selective for NK 3 receptors. In general, the compounds ofthe invention which were tested demonstrated statistically significant binding activity in Test A and Test B with a K, of 1 mM or much less typically being measured. Rabbit Pulmonary Artery: NK L in vitro functional assay (Test C) The ability of a compound of the invention to antagonize the action ofthe agonist Ac- [Arg 6 , Sar 9 , Met(O 2 ) u ] Substance P (6-11), ASMSP, in a pulmonary tissue may be demonstrated as follows. Male New Zealand white rabbits are euthanized via i.v. injection into the ear vein with 60 mg/kg Nembutal (50 mg/mL). Preceding the Nembutal into the vein is Heparin (1000 units/mL) at 0.0025 mL/kg for anticoagulant purposes. The chest cavity is opened from the top ofthe rib cage to the sternum and the heart, lungs and part ofthe trachea are removed. The pulmonary arteries are isolated from the rest of the tissues and cut in half to serve as pairs. The segments are suspended between stainless steel stirrups, so as not to remove any ofthe endothelium, and placed in water-jacketed (37.0 °C) tissue baths containing physiological salt solution ofthe following composition (mM): NaCl, 118.0; KCl, 4.7; CaCl 2 , 1.8; MgCl 2 , 0.54; NaH 2 PO 4 , 1.0; NaHCO 3 , 25.0; glucose, 11.0; indomethacin, 0.005 (to inhibit cyclooxygenase); and J/-Propranolol, 0.001 (to block β receptors); gassed continuously with 95% O 2 -5% CO 2 . Responses are measured on a Grass polygraph via Grass FT-03 transducers. Initial tension placed on each tissue is 2 grams, which is maintained throughout the 1.0 hour equilibration period. Tissues are washed with the physiological salt solution at 15 minute intervals. At the 30 and 45 minute wash the following treatments are added: 1 x 10 "6 M Thiorphan (to block E.C.3.4.24.11), 3 x 10 "8 M (S)-N-[2-(3,4-dichlorophenyl)-4-[4-(2- oxoperhydropyrimidin-l-yl)piperidino]butyl]-N-methylbenzamide (to block NK 2 receptors), and the given concentration ofthe compound being tested. At the end ofthe 1.0 h equilibration, 3 x 10 "6 M Phenylephrine hydrochloride is added for 1.0 h. At the end of 1.0 h, a dose relaxation curve to ASMSP is done. Each tissue is treated as a individual and is considered finished when it fails to relax further for 2 consecutive doses. When a tissue is complete, 1 x 10 "3 M Papaverine is added for maximum relaxation. Percent inhibition is determined when a tested compound produces a statistically significant (p < 0.05) reduction ofthe total relaxation which is calculated using the total relaxation ofthe Papaverine as 100%. Potencies of the compounds are determined by calculating the apparent dissociation constants (K B ) for each concentration tested using the standard equation: KB= [antagonist]/ (dose ratio - 1) where dose ratio = antilog[(agonist -log molar EC 50 without compound) - (-log molar EC 50 with compound)]. The K B values may be converted to the negative logarithms and expressed as -log molar KB (i.e. pK B ). For this evaluation, complete concentration-response curves for agonist obtained in the absence and presence ofthe compound tested using paired pulmonary artery rings. The potency ofthe agonist is determined at 50% of its own maximum relaxation in each curve. The EC 50 values are converted to negative logarithms and expressed as -log molar EC 50 . NK, in vitro functional assay (Test D) The ability of a compound ofthe invention to antagonize the action ofthe agonist [β- ala8] NKA (4-10), BANK, in a pulmonary tissue may be demonstrated as follows. Male New Zealand white rabbits are euthanized via i.v. injection into the ear vein with 60 mg/kg Nembutal (50 mg/mL). Preceding the Nembutal into the vein is Heparin (1000 units/mL) at 0.0025 mL/kg for anticoagulant purposes. The chest cavity is opened from the top ofthe rib cage to the sternum and a small incision is made into the heart so that the left and right pulmonary arteries can be cannulated with polyethylene tubing (PE260 and PE190 respectively). The pulmonary arteries are isolated from the rest of the tissues, then rubbed over an intimal surface to remove the endothelium, and cut in half to serve as pairs. The segments are suspended between stainless steel stirrups and placed in water-jacketed (37.0 °C) tissue baths containing physiological salt solution ofthe following composition (mM): NaCl, 118.0; KCl, 4.7; CaCl 2 , 1.8; MgCl 2 , 0.54; NaH 2 PO 4 , 1.0; NaHCO 3 , 25.0; glucose, 11.0; and indomethacin, 0.005 (to inhibit cyclooxygenase); gassed continuously with 95% O 2 -5% CO 2 . Responses are measured on a Grass polygraph via Grass FT-03 transducers. Initial tension placed on each tissue is 2 g, which is maintained throughout the 45 min equilibration period. Tissues are washed with the physiological salt solution at 15 min intervals. After the 45 min equilibration period, 3 x 10 "2 M KCl is given for 60 min to test the viability ofthe tissues. The tissues are then washed extensively for 30 min. The concentration ofthe compound being tested is then added for 30 min. At the end ofthe 30 min, a cumulative dose response curve to BANK is performed. Each tissue is treated as a individual and is considered finished when it fails to contract further for 2 consecutive doses. When a tissue is complete, 3 x 10 2 M BaCl 2 is added for maximum contraction. Percent inhibition is determined when a tested compound produces a statistically significant (p < 0.05) reduction ofthe total contraction which is calculated using the total contraction ofthe BaCl 2 as 100%. Potencies ofthe compounds are determined by calculating the apparent dissociation constants (K B ) for each concentration tested using the standard equation: K B = [antagonist]/ (dose ratio - 1) where dose ratio = antilog[(agonist -log molar EC 50 without compound) - (-log molar EC 50 with compound)]. The K B values may be converted to the negative logarithms and expressed as -log molar K B (i.e. pK B ). For this evaluation, complete concentration-response curves for agonist obtained in the absence and presence ofthe compound tested using paired pulmonary artery rings. The potency ofthe agonist is determined at 50% of its own maximum relaxation in each curve. The EC 50 values are converted to negative logarithms and expressed as -log molar EC 50 . NK X and NK 2 in vivo functional assay (Test E) The activity of a compound as an antagonist of NK, and/or NK 2 receptors also may be demonstrated in vivo in laboratory animals as described in: Buckner et al. "Differential Blockade by Tachykinin NK, and NK 2 Receptor Antagonists of Bronchoconstriction Induced by Direct-Acting Agonists and the Indirect-Acting Mimetics Capsaicin, Serotonin and 2- Methyl-Serotonin in the Anesthetized Guinea Pig." J. Pharm. Exp. Ther.,1993. Vol 267(3), pp.1168-1175. The assay is carried out as follows. Compounds are tested in anesthetized guinea pigs pretreated with i.v. indomethacin (10 mg/kg, 20 min), propranolol (0.5 mg/kg, 15 min), and fhiorphan (10 mg/kg, 10 min). Antagonists or vehicle are administered i.v. and orally, 30 and 120 min prior to increasing concentrations of agonist, respectively. The agonists used in these studies are ASMSP (Ac-[Arg 6 ,Sar 9 ,Met(O 2 )"]-SP(6-l 1)) and BANK (β-ala-8 NKA4-10). Administered i.v., ASMSP is selective for NK, receptors, and BANK is selective for NK 2 receptors. Maximum response is defined as zero conductance (G L , 1/Rp). ED 50 values are calculated (the dose of agonist resulting in a reduction of G L to 50% of baseline), and converted to the negative logarithm (-logED 50 ). The ED 50 values, obtained in the presence (P) and absence (A) of antagonist, are used to calculate a Dose Ratio (P/A), an expression of potency. Data are expressed as mean ± SEM and statistical differences were determined using ANOVA/Tukey-Kramer and Student's t-test , with p < 0.05 considered statistically significant. Compounds ofthe present invention exhibit marked activity in the foregoing tests and are considered useful for the treatment of those diseases in which the NK, and/or NK 2 receptor is implicated, for example, in the treatment of asthma and related conditions.

Standard reductive amination refers to the typical procedure in which a solution of an amine (1-1.2 equiv.), an aldehyde (1-1.2 equiv.) and acetic acid (2 equiv.) is stirred in methanol for 5 to 60 min before adding NaBH 3 CN (1.7 equiv.). After 1-16 h the reaction is optionally concentrated, dissolved in DCM, and washed with saturated sodium bicarbonate and then purified by chromatography. Standard Swern oxidation conditions refer to the oxidation of an alcohol to the corresponding aldehyde according to Mancuso, AJ; Huang, SL; Swern, D; J. Org. Chem.; 1978, 2840. Standard formation of an acid chloride refers to the typical procedure in which a solution of a substituted carboxylic acid in DCM is stirred with 1-1.2 equiv. of oxalyl chloride and a catalytic amount of DMF for 1-12 h, concentrated under reduced pressure, and used without purification. Standard acylation refers to the typical procedure in which an acid chloride (1-1.2 equiv.) is added to a stirred solution of an amine (1-1.2 equiv.) and triethylamine (2 equiv.) in DCM. After 1-16 h the reaction is optionally concentrated, dissolved in DCM, and washed with saturated sodium bicarbonate and then purified by chromatography. Where noted that a final compound was converted to the citrate salt, the free base was combined with citric acid (1.0 equiv.) in methanol, concentrated under reduced pressure and dried under vacuum (25-70 °C). When indicated that a compound was isolated by filtration from Et 2 O, the citrate salt ofthe compound was stirred in Et^O for 12-18 h, removed by filtration, washed with Et 2 O, and dried under vacuum at 25-70 °C. Where noted that a final compound was converted to the hydrochloride salt, a solution of HC1 in Et 2 O was added with stirring to a solution of the purified free base in DCM or methanol. The resulting precipitate was collected by filtration and dried under vacuum. Analytical HPLC conditions employed were the following: Hewlett Packard HP 1100 system using a Luna C18(2) 4.6x75 mm, 3 micron column (Phenomenex; Torrance, CA) with the following gradient: 0-0.5 min; 20% Solvent B, then ramping linearly to 85% Solvent B at 15 min at a fixed flow rate of 2 mL/min (Solvent A: 0.1% TFA in water; Solvent B: 0.1% TFA in methanol) using UN detection at 255 nm. Example 1 Ν-[2-(S)-(3,4-Dichlorophenyl)-3-aminocarbonylpropyl]-Ν-methyl-3-cyano-2-methoxy-l- naphthamide To a stirred solution of N-[2-(S)-(3,4-dichlorophenyl)-3-carboxypropyl]-N-methyl-3- cyano-2-methoxy-l-naphthamide and diisopropylethyl amine (2.0 equiv.) in DCM was added tetramethyl fluoroformamidinium hexaflurophosphate (TFFH) (1.2 equiv.).
