     BACKGROUND OF THE INVENTION 
     The present invention relates to a genus of substituted oximes, hydrazones and olefins useful as antagonists of tachykinin receptors, in particular as antagonists of the neuropeptides neurokinin-1 receptor (NK 1 ) and/or neurokinin-2 receptor (NK 2 ) and/or neurokinin-3 receptor (NK 3 ). 
     Neurokinin receptors are found in the nervous system and the circulatory system and peripheral tissues of mammals, and therefore are involved in a variety of biological processes. Neurokinin receptor antagonists are consequently expected to be useful in the treatment or prevention of various mammalian disease states, for example asthma, cough, bronchospasm, inflammatory diseases such as arthritis, central nervous system conditions such as migraine and epilepsy, nociception, and various gastrointestinal disorders such as Crohn&#39;s disease. 
     In particular, NK 1  receptors have been reported to be involved in microvascular leakage and mucus secretion, and NK 2  receptors have been associated with smooth muscle contraction, making NK 1  and NK 2  receptor antagonists especially useful in the treatment and prevention of asthma. 
     Some NK 1  and NK 2  receptor antagonists have previously been disclosed: arylalkylamines were disclosed in U.S. Pat. No. 5,350,852, issued Sep. 27, 1994, and spiro-substituted azacycles were disclosed in WO 94/29309, published Dec. 22, 1994.

     DETAILED DESCRIPTION 
     As used herein, the term &#34;alkyl&#34; means straight or branched alkyl chains. &#34;Lower alkyl&#34; refers to alkyl chains of 1-6 carbon atoms and, similarly, lower alkoxy refers to alkoxy chains of 1-6 carbon atoms. 
     &#34;Cycloalkyl&#34; means cyclic alkyl groups having 3 to 6 carbon atoms. &#34;Bridged cycloalkyl&#34; refers to C 7  -C 10  saturated rings comprised of a cycloalkyl ring or a fused bicycloalkyl ring and an alkylene chain joined at each end to non-adjacent carbon atoms of the ring or rings. Examples of such bridged bicycloalkyl rings are adamantyl, myrtanyl, noradamantyl, norbornyl, bicyclo 2.2.1!heptyl, 6,6-dimethylbicyclo 3.1.1!heptyl, bicyclo 3.2.1!octyl, and bicyclo 2.2.2!octyl. 
     &#34;Aryl&#34; means phenyl, naphthyl, indenyl, tetrahydronaphthyl, indanyl, anthracenyl or fluorenyl. 
     &#34;Halogeno&#34; refers to fluoro, chloro, bromo or iodo atoms. 
     &#34;Heterocycloalkyl&#34; refers to 4- to 6-membered saturated rings comprising 1 to 3 heteroatoms independently selected from the group consisting of --O--, --S-- and --N(R 19 )--, with the remaining ring members being carbon. Examples of heterocycloalkyl rings are tetrahydrofuranyl, pyrrolidinyl, piperidinyl, morpholinyl, thiomorpholinyl and piperazinyl. R 4  -heterocycloalkyl refers to such groups wherein substitutable ring carbon atoms have an R 4  substituent. 
     &#34;Heteroaryl&#34; refers to 5- to 10-membered single or benzofused aromatic rings comprising 1 to 4 heteroatoms independently selected from the group consisting of --O--, --S-- and --N═, provided that the rings do not include adjacent oxygen and/or sulfur atoms. Examples of single-ring heteroaryl groups are pyridyl, isoxazolyl, oxadiazolyl, furanyl, pyrrolyl, thienyl, imidazolyl, pyrazolyl, tetrazolyl, thiazolyl, thiadiazolyl, pyrazinyl, pyrimidinyl, pyridazinyl and triazolyl. Examples of benzofused heteroaryl groups are indolyl, quinolinyl, thianaphthenyl and benzofurazanyl. N-oxides of nitrogen-containing heteroaryl groups are also included. All positional isomers are contemplated, e.g., 1-pyridyl, 2-pyridyl, 3-pyridyl and 4-pyridyl. R 4  -heteroaryl refers to such groups wherein substitutable ring carbon atoms have an R 4  substituent. 
     Where R 2  and R 3  or R 6  and R 7  substituents on a nitrogen atom form a ring and additional heteroatoms are present, the rings do not include adjacent oxygen and/or sulfur atoms or three adjacent hetero-atoms. Typical rings so formed are morpholinyl, piperazinyl and piperidinyl. 
     In the structures in the definition of Z, the substituents L and L 1  may be present on any substitutable carbon atom, including in the second structure the carbon to which the --N(R 26 )(R 27 ) group is attached. 
     In the above definitions, wherein variables R 6 , R 7 , R 8 , R 9 , R 10 , R 13 , R 14 , R 15 , R 30  and R 31 , for example, are said to be independently selected from a group of substituents, we mean that R 6 , R 7 , R 8 , R 9 , R 10 , R 13 , R 14 , R 15 , R 30  and R 31  are independently selected, but also that where an R 6 , R 7 , R 8 , R 9 , R 10 , R 13 , R 14 , R 15 , R 30  or R 31  variable occurs more than once in a molecule, those occurrences are independently selected (e.g., if B is ═NR 6  -- wherein R 6  is hydrogen, X can be --N(R 6 )-- wherein R 6  is ethyl). Similarly, R 4  and R 5  can be independently selected from a group of substituents, and where more than one R 4  and R 5  are present, the substitutents are independently selected; those skilled in the art will recognize that the size and nature of the substituent(s) will affect the number of substituents which can be present. 
     Compounds of formula I can have at least one asymmetrical carbon atom and all isomers, including diastereomers, enantiomers and rotational isomers, as well as E and Z isomers of the oxime, hydrazone and olefin groups, are contemplated as being part of this invention. The invention includes d and I isomers in both pure form and in admixture, including racemic mixtures. Isomers can be prepared using conventional techniques, either by reacting optically pure or optically enriched starting materials or by separating isomers of a compound of formula I. 
     Those skilled in the art will appreciate that for some compounds of formula I, one isomer will show greater pharmacological activity than other isomers. 
     Compounds of the invention have at least one amino group which can form pharmaceutically acceptable salts with organic and inorganic acids. Examples of suitable acids for salt formation are hydrochloric, sulfuric, phosphoric, acetic, citric, oxalic, malonic, salicylic, malic, fumaric, succinic, ascorbic, maleic, methanesulfonic and other mineral and carboxylic acids well known to those in the art. The salt is prepared by contacting the free base form with a sufficient amount of the desired acid to produce a salt. The free base form may be regenerated by treating the salt with a suitable dilute aqueous base solution such as dilute aqueous sodium bicarbonate. The free base form differs from its respective salt form somewhat in certain physical properties, such as solubility in polar solvents, but the salt is otherwise equivalent to its respective free base forms for purposes of the invention. 
     Certain compounds of the invention are acidic (e.g., those compounds which possess a carboxyl group). These compounds form pharmaceutically acceptable salts with inorganic and organic bases. Examples of such salts are the sodium, potassium, calcium, aluminum, gold and silver salts. Also included are salts formed with pharmaceutically acceptable amines such as ammonia, alkyl amines, hydroxyalkylamines, N-methylglucamine and the like. 
     Compounds of formula I can be prepared using methods well known to those skilled in the art. Following are typical procedures for preparing various compounds; the skilled artisan will recognize that other procedures may be applicable, and that the procedures may be suitably modified to prepare other compounds within the scope of formula I.

     The in vitro and in vivo activity of the compounds of formula I can be determined by the following procedures. 
     In Vitro Procedure to Identify NK 1  Activity 
     Test compounds are evaluated for their ability to inhibit the activity of the NK 1  agonist Substance P on the isolated guinea pig vas deferens. Freshly cut vas deferens are removed from male Hartley guinea pigs (230-350 g) and suspended in 25 ml tissue baths containing Kreb&#39;s Henseleit solution warmed to 37° C. and constantly aerated with 95% O 2  and 5% CO 2 . Tissues are adjusted to 0.5 g and allowed to equilibrate for a period of 30 minutes. The vas deferens are exposed to an electrical field stimulation (Grass S48 Stimulator) every 60 seconds at an intensity that will cause the tissue to contract 80% of its maximum capacity. All responses are recorded isometrically by means of a Grass force displacement transducer (FT03) and Harvard electronic recorder. Substance P inhibits the electrical field stimulated-induced contractions of the guinea pig vas deferens. In unpaired studies, all tissues (control or drug treated) are exposed to cumulative concentations of Substance P (1×10 -10  M-7×10 -7  M). Single log-concentations of the test compounds are given to separate tissues and allowed to equilibrate for 30 minutes before a Substance P concentation-response curve is generated. At least 5 separate tissues are used for each control and individual drug-concentation for every drug assay. 
     Inhibition of the Substance P is demonstrated by a rightward shift of its concentration-response curve. These shifts are used to determine the pA 2  value, which is defined as the negative log of the molar concentration of the inhibitor which would require that twice as much agonist be used to elicit a chosen response. This value is used to determine relative antagonist potency. 
     Isolated Hamster Trachea NK 2  Assay 
     General methodology and characterization of hamster trachea responses to neurokinin agonists as providing an NK 2  monoreceptor assay is found in C. A. Maggi, et al., Eur. J. Pharmacol 166 (1989) 435 and J. L. Ellis, et al., J. Pharm. Exp. Ther. 267 (1993) 95. 
     Continuous isometric tension monitoring is achieved with Grass FT-03 force displacement transducers connected to Buxco Electronics preamplifiers built into a Graphtec Linearcorder Model WR 3310. 
     Male Charles River LAK:LVG (SYR) hamsters, 100-200 g fed weight, are stunned by a sharp blow to the head, loss of corneal reflex is assured, the hamsters are sacrificed by thoractomy and cutting the heart. Cervical trachea segments are removed to room temperature Krebs buffer, pH 7.4, aerated with 95% O 2  -5% CO 2  gas and cleaned of adhering tissue. The segments are cut into two 3-4 mm long ring segments. Tracheal rings are suspended from transducers and anchored in 15.0 ml water jacketed organ baths by means of stainless steel hooks and 6-0 silk. Baths are filled with Krebs buffer, pH 7.4, maintained at 37° C. and continuously aerated with 95% O2-5% CO 2  gas. Tracheal rings are placed under 1.0 g initial tension and allowed a 90 min equilibration period with four 1 μM NKA challenge, wash and recovery cycles at 20 min intervals. 30 min vehicle pretreatment is followed by cumulative additions of rising doses of NKA (3 nM-1 μM final concentration, 5 min intervals between additions). The final NKA response is followed by a 15 min wash and recovery period. 30 min pretreatment with a test compound or its vehicle is followed by cumulative additions of rising doses of NKA (3 nM-10μM final concentration if necessary, 5 min intervals between additions). The final NKA response is followed by a 1 mM carbachol challenge to obtain a maximal tension response in each tissue. 
     Tissue responses to NKA are recorded as positive pen displacements over baseline and converted to grams tension by comparison to standard weights. Responses are normalized as a % of the maximal tissue tension. ED 50  &#39;s are calculated for NKA from the control and treated NKA dose responses and compared. Test compounds resulting in an agonist dose ratio ≧2 at a screening concentration of 1 μM (i.e. pA 2 ≧ =6.0) are considered actives. Further dose response data is obtained for actives so that an apparent pA 2  estimate can be calculated. pA 2  is calculated either by estimation of K i  as described by Furchgott (where pA 2  =-Log K i , R. F. Furchgott, Pharm. Rev. 7  1995! 183) or by Shild Plot Analysis (O. Arunlakshana &amp; H. O. Shild, Br. J. Pharmacol. 14 1959! 48) if the data is sufficient. 
     Effect of NK 1  Antagonists on Substance P-Induced Airway Microvascular Leakage in Guinea Pigs 
     Studies are performed on male Hartley guinea pigs ranging in weight from 400-650 g. The animals are given food and water ad libitum. The animals are anesthetized by intraperitoneal injection of dialurethane (containing 0.1 g/ml diallylbarbituric acid, 0.4 g/ml ethylurea and 0.4 g/ml urethane). The trachea is cannulated just below the larynx and the animals are ventilated (V T  =4 ml, f=45 breaths/min) with a Harvard rodent respirator. The jugular vein is cannulated forthe injection of drugs. 
     The Evans blue dye technique (Danko, G. et al., Pharmacol. Commun., 1, 203-209, 1992) is used to measure airway microvascular leakage (AML). Evans blue (30 mg/kg) is injected intravenously, followed 1 min later by i.v. injection of substance P (10 μg/kg). Five min later, the thorax is opended and a blunt-ended 13-guage needle passed into the aorta. An incision is made in the right atrium and blood is expelled by flushing 100 ml of saline through the aortic catheter. The lungs and trachea are removed en-bloc and the trachea and bronchi are then blotted dry with filter paper and weighed. Evans blue is extracted by incubation of the tissue at 37° C. for 18 hr in 2 ml of formamide in stoppered tubes. The absorbance of the formamide extracts of dye is measured at 620 nm. The amount of dye is calculated by interpolation from a standard curve of Evans blue in the range 0.5-10 μg/ml in formamide. The dye concentration is expressed as ng dye per mg tissue wet weight. Test compounds were suspended in cyclodextran vehicle and given i.v. 5 min before substance P. 
     Measurement of NK 2  Activity In Vivo 
     Male Hartley guinea pigs (400-500 gm) with ad lib. access to food and water are anesthetized with an intraperitoneal injection of 0.9 ml/kg dialurethane (containing 0.1 g/m diallylbarbituric acid, 0.4 g/ml ethylurea and 0.4 g/ml urethane). After induction of a surgical plane of anesthesia, tracheal, esophageal and jugular venous cannulae are implanted to facilitate mechanical respiration, measurement of esophageal pressure and administration of drugs, respectively. 
     The guinea pigs are placed inside a whole body plethysmograph and the catheters connected to outlet ports in the plethysmograph wall. Airflow is measured using a differential pressure transducer (Validyne, Northridge CA, model MP45-1, range ±2 cmH 2  O) which measures the pressure across a wire mesh screen that covers a 1 inch hole in the wall of the plethysmograph. The airflow signal is electrically integrated to a signal proportional to volume. Transpulmonary pressure is measured as the pressure difference between the trachea and the esophagus using a differential pressure transducer (Validyne, Northridge, CA, model MP45-1, range ±20 cm H 2  O). The volume, airflow and transpulmonary pressure signals are monitored by means of a pulmonary analysis computer (Buxco Electronics, Sharon, CT, model 6) and used for the derivation of pulmonary resistance (R L ) and dynamic lung compliance (C Dyn ). 
     Bronchoconstriction Due to NKA 
     Increasing iv doses of NKA are administered at half log (0.01-3 μg/kg) intervals allowing recovery to baseline pulmonary mechanics between each dose. Peak bronchoconstriction occurs within 30 seconds after each dose of agonist. The dose response is stopped when C Dyn  is reduced 80-90% from baseline. One dose-response to NKA is performed in each animal. Test compounds are suspended in cyclodextran vehicle and given i.v. 5 min before the initiation of the NKA dose response. 
     For each animal, dose response curves to NKA are constructed by plotting the percent increase in R L  or decrease in C Dyn  against log dose of agonist. The doses of NKA that increased R L  by 100% (R L  100) or decreased C Dyn  by 40% (C Dyn  40) from baseline values are obtained by log-linear interpolation of the dose response curves. 
     Neurokinin Receptor Binding Assay(s) 
     Chinese Hamster ovary (CHO) cells transfected with the coding regions for the human neurokinin 1 (NK1) of the human neurokinin 2 (NK2) receptors are grown in Dulbecco&#39;s minimal essential medium supplemented with 10% fetal calf serum, 0.1 mM non-essential amino acids, 2 mM glutamine, 100units/ml of penicillin and streptomycin, and 0.8 mg of G418/ml at 37° C. in a humidified atmosphere containing 5% CO 2 . 
     Cells are detached from T-175 flasks with a sterile solution containing 5 mM EDTA in phosphate buffered saline. Cells are harvested by centrifugation and washed in RPMl media at 40° C. for 5 minutes. The pellet is resuspended inTris-HCl (pH7.4) containing 1 uM phsphoramidon and 4 ug/ml of chymostatin at a cell density of 30×10 6  cells/ml. The suspension is then homogenized in a Brinkman Polytron (setting 5) for 30-45 seconds. The homogenate is centrifuged at 800×g for 5 min at 4° C. to collect unbroken cells and nuclei. The supernatant is centrifuged in a Sorvall RC5C at 19,000 rpm (44,00×g) for 30 min at 4° C. The pellet is resuspended, an aliquot is removed for a protein determination (BCA) and washed again. The resulting pellet is stored at -80° C. 
     To assay receptor binding, 50 μl of   3  H!-Substance P (9-Sar, 11 -Met  02!) (specific activity 41 Ci/mmol) (Dupont-NEN) (0.8 nM for the NK-1 assay) or   3  H!-Neurokinin A (specific activity 114 Ci/mmole) (Zenca) (1.0 nM for the NK-2 assay) is added to tubes containing buffer (50 mM Tris-HCl (pH 7.4) with 1 mM MnCl 2  and 0.2% Bovine Serum Albumin) and either DMSO or test compound. Binding is initiated by the addition of 100 μl of membrane (10-20 μg) containing the human NK-1 or NK-2 receptor in a final volume of 200 μl. After 40 minutes at room temperature, the reaction is stopped by rapid filtration onto Whatman GF/C filters which have been presoaked in 0.3% polyethylenimine. Filters are washed 2 times with 3 ml of 50 mM Tris-HCl (pH7.4). Filters are added to 6 mIs of Ready-Safe liquid scintillation cocktail and quantified by liquid scintillation spectrometry in a LKB 1219 RackBeta counter. Non-specific binding is determined by the addition of either 1 μM of CP-99994 (NK-1) or 1 μM SR-48968 (NK-2) (both synthesized by the chemistry department of Schering-Plough Research Institute). IC 50  values are determined from competition binding curves and Ki values are determined according to Cheng and Prusoff using the experimentally determined value of 0.8 nM for the NK-1 receptor and 2.4 nM for the NK-2 receptor. 
     NK 3  activity is determined by following a procedure similar to that described in the literature, e.g., Molecular PharmacoL, 48 (1995), p. 711-716. 
     % Inhibition is the difference between the percent of maximum specific binding (MSB) and 100%. The percent of MSB is defined by the following equation, wherein &#34;dpm&#34; is disintegrations per minute: ##EQU1## 
     It will be recognized that compounds of formula I exhibit NK 1 , NK 2  and/or NK 3  antagonist activity to varying degrees, e.g., certain compounds have strong NK 1  antagonist activity, but weaker NK 2  and NK 3  antagonist activity, while others are strong NK 2  antagonists, but weaker NK 1  and NK 3  antagonists. While compounds with approximate equipotency are preferred, it is also within the scope of this invention to use compounds of with unequal NK 1  /NK 2  /NK 3  antagonist activity when clinically appropriate. 
     Using the test procedures described above, the following data (% inhibition or Ki) were obtained for preferred and/or representative of formula I:
