CROSS-REFERENCE TO RELATED APPLICATIONS 
     This application is a continuation-in-part of application Ser. No. 201,894, filed Oct. 29, 1980, now U.S. Pat. No. 4,296,129. 
    
    
     BACKGROUND OF THE INVENTION 
     This invention relates to new chemical compounds, and more particularly it relates to derivatives of propenamide, 2-methylpropenamide, 2-butenamide, 2-methyl-2-butenamide and cyclopropanecarboxamide. Said derivatives are substituted on the nitrogen atom by an alkyl or cycloalkyl group. Additionally, said propenamide, 2-methylpropenamide, 2-butenamide and 2-methyl-2-butenamide derivatives are further substituted at the 3-position, and said cyclopropanecarboxamide derivatives are further substituted at the 2-position, by a (carboxyalkanamido)phenyl or (carboxyalkenamido)phenyl group. These compounds are useful as antagonists of the slow-reacting substance of anaphylaxis (SRS-A). 
     It is known that certain substances, known as mediators of anaphylaxis, play an important role in inducing an allergic reaction, such as bronchospastic attack or allergic rhinitis, in a human subject. Two examples of such mediators are histamine and the slow-reacting substance of anaphylaxis (SRS-A), the latter substance being a very important mediator in allergic bronchial asthma. SRS-A is a substance which is synthesized and released in or near target tissues, in a sensitive (allergic) human subject, shortly after challenge with the appropriate antigen. The human bronchus is particularly sensitive to SRS-A. 
     Rational approaches to drug therapy to prevent, remove or ameliorate the symptoms of allergic reactions have focussed on either blocking the release of mediators of anaphylaxis, or, on the other hand, on antagonizing their effects. Disodium cromoglycate (The Merck Index, Merck &amp; Co., Inc., Rahway, New Jersey, 9th Edition, 1976, 2585) is a drug which has recently been introduced and which blocks the release of mediators of anaphylaxis, and commercially available drugs which antagonize histamine (antihistamines) are well-known (e.g. methapyrilene, diphenhydramine, chlorpheniramine). Conversely, there is a paucity of substances known which antagonize SRS-A, and none of them is used in clinical practice today. One agent has been widely studied (FPL 55712--Agents and Actions, 9, 133 [1979]). 
     SUMMARY OF THE INVENTION 
     This invention provides novel carboxamide compounds of the formula ##STR1## and the pharmaceutically-acceptable salts thereof; wherein R 1  is selected from the group consisting of hydrogen, alkyl having 1 to 4 carbons, and --CH 2  --CH 2  --NR 3  R 4 , wherein R 3  and R 4  are each alkyl having 1 to 3 carbons; 
     R 2  is selected from the group consisting of alkyl having 8 to 15 carbons and cycloalkyl having from 6 to 12 carbons; 
     Q is selected from the group consisting of ##STR2##  wherein R 5  and R 6  are each selected from the group consisting of hydrogen and methyl; 
     and X is selected from the group consisting of cis-vinylene, ethylene and ##STR3## wherein R 7  and R 8  are each selected from the group consisting of hydrogen and methyl; 
     with the proviso that when Q is ##STR4##  the two groups attached to the ##STR5##  group must have a trans relationship to each other. 
     When either of R 1  and R 2  is an alkyl group, it can be straight-chain or branched-chain. R 3  and R 4   can be straight-chain or branched-chain. 
     This invention also provides a method of antagonizing the spasmogenic activity of the slow-reacting substance of anaphylaxis (SRS-A) in a human subject, which comprises administering to said subject an effective amount of a compound of the formula I, or a pharmaceutically-acceptable salt thereof. The compounds of formula I are antagonists of the effects of slow-reacting substance of anaphylaxis (SRS-A), and they are useful therefore for preventing and treating certain obstructive airways diseases, notably allergic bronchial asthma, allergic rhinitis and certain skin disorders in human subjects. 
     Still further, this invention provides pharmaceutical compositions, suitable for administration to a human subject, which comprise a pharmaceutically-acceptable carrier and a compound of the formula I, or a pharmaceutically-acceptable salt thereof. 
     A first preferred group of compounds of this invention is the group of compounds of formula I, wherein R 1  is hydrogen, R 2  is said alkyl, Q is ##STR6## and X is cis-vinylene. Within this group, the compounds wherein R 5  and R 6  are both hydrogen are particularly preferred. Especially preferred is N-decyl-3-(3-[cis-3-carboxypropenamido]phenyl)propenamide, a compound of formula I, wherein R 1  is hydrogen, Q is --CH═CH--, R 2  is decyl, X is cis-vinylene and the two groups on the phenyl ring are in a meta relationship to each other. 
     A second preferred group of compounds of this invention is the group of compounds of formula I, wherein R 1  is hydrogen, R 2  is said alkyl, Q is ##STR7## and X is cis-vinylene. 
     DETAILED DESCRIPTION OF THE INVENTION 
     In this specification, the compounds of formula I, and several of the intermediates leading thereto, are named as derivatives of propenamide, 2-methyl-propenamide, 2-butenamide, 2-methyl-2-butenamide and cyclopropanecarboxamide, which have structures II, III, IV, V and VI, respectively, viz: ##STR8## The derived term &#34;propenamido&#34; refers to the radical --NH--CO--CH═CH 2 , and the terms &#34;propanamido&#34; and &#34;butanamido&#34; refer to the radicals --NH--CO--CH 2  --CH 3  and --NH--CO--CH 2  --CH 2  --CH 3 , respectively. 
     When R 2  is an alkyl group, it can be straight-chain or branched-chain. However, in this specification, when the R 2  group is an alkyl group it is named according to the system of the Chemical Abstracts Service of the American Chemical Society. This means that within a given name each individual term denotes a straight-chain radical, having the free valency at the 1-position. For example decyl denotes the group CH 3  (CH 2 ) 8  CH 2  --, the group (CH 3  CH 2  CH 2  CH 2  CH 2 ) 2  CH-- is named 1-pentylhexyl and the group (CH 3 ) 2  CHCH 2  CH 2  CH 2  CH 2  CH 2  -- is named 6-methylheptyl. 
     The carboxamide compounds of formula I, wherein R 1  is hydrogen, can be prepared by reaction of the appropriate amine of the formula ##STR9## with a cyclic anhydride selected from the group consisting of maleic anhydride, succinic anhydride, glutaric anhydride, 3-methylglutaric anhydride and 3,3-dimethylglutaric anhydride. The reaction is conveniently carried out by heating substantially equimolar quantities of the reagents in a reaction-inert solvent. A wide variety of solvents can be used for this purpose. The major requirements for such a solvent are that it substantially dissolves at least one of the reactants, it does not adversely interact with either of the reactants or the product, and the product can be recovered from it at the end of the reaction. Typical solvents which can be used are hydrocarbons, such as cyclohexane, decalin, tetralin, benzene, toluene and xylene; ethers such as 1,2-dimethoxyethane and dioxane; ketones, such as methyl isobutyl ketone and cyclohexanone; low molecular weight esters, such as ethyl acetate and butyl acetate; alkanols, such as methanol, ethanol and isopropanol; and mixtures of these solvents. The reaction is usually conducted at a temperature in the range from about 60° to about 150° C., and preferably from about 80° to 120° C. At about 90° C. the reaction is often complete within a few minutes, although in some instances it is necessary to continue the reaction for up to two hours. After the reaction is substantially complete, the compound of formula I is recovered by conventional techniques. For example, if the compound of formula I is out of solution it can be recovered by filtration; otherwise the solvent can be removed by evaporation. 
     Alternatively, the compound of formula I can be obtained by contacting substantially equimolar quantities of a compound of formula VII and one of the aforesaid cyclic anhydrides, at elevated temperature, in the molten state. Temperatures in the range from about 60° to about 150° C. are commonly used, with temperatures from about 80° to 120° C. being preferred. At about 90° C., the reaction is often complete within a few minutes although in some instances it is necessary to continue the reaction for up to two hours. At the end of the reaction, the product can be recovered by conventional methods. One convenient method involves cooling the reaction medium and then adding about a 10-fold excess of a solvent in which the product is only slightly soluble but in which the starting materials are readily soluble. The product is recovered by filtation. The particular solvent which is used for this purpose will vary according to the precise structure of the product, but an appropriate solvent will be chosen readily by one skilled in the art. Lower alkanols, such as methanol, ethanol and isopropanol, and low molecular weight esters, such as ethyl acetate, are commonly used. 
     A compound of formula I can be purified by conventional means, e.g. chromatography and/or recrystallization from an appropriate solvent. 
     The compounds of formula VII are obtained by reduction of the corresponding nitro compound of the formula ##STR10## A convenient way of carrying out this reduction is to use iron in glacial acetic acid. Thus, in one method, the compound of formula VIII is dissolved in glacial acetic acid, the solution is heated to 85°-90° C., and then an approximately equal weight of iron powder is added portionwise with stirring, during about 10 to 15 minutes. The reaction mixture is stirred an additional 15 minutes and then the solids are removed by filtration. The solids are washed with acetic acid, and then the combined acetic acid solutions are evaporated to give the compound of formula VII. In many instances, the compound of formula VII is sufficiently pure in its crude state for reaction with the appropriate cyclic anhydride. However, it can be purified by conventional techniques such as chromatography and/or recrystallization, if desired. 
     The compounds of formula VIII can be obtained from the corresponding compound of the formula ##STR11## Conversion of a compound of the formula IX into a compound of the formula VIII involves activation of the carboxy group followed by reaction with the appropriate amine of formula R 2  --NH 2 . 
     One convenient way of activating the carboxy group in a compound of formula IX involves conversion into the corresponding acid chloride. This is normally carried out by heating the acid with about 1.5 molar equivalents of thionyl chloride, in benzene, at reflux temperature, for about two hours. Removal of all volatile materials by evaporation in vacuo then affords the acid chloride in essentially quantitative yield. In most instances the acid chloride is sufficiently pure for direct reaction with the amine of formula R 2  --NH 2  ; however, it can be purified further by recrystallization from a solvent such as carbon tetrachloride, if desired. 
     Reaction of the acid chloride of a compound of formula IX with an amine of formula R 2  --NH 2  is normally accomplished by dissolving the amine in a reaction-inert organic solvent such as tetrahydrofuran, cooling the solution to about 0° C., and then adding a solution of about 0.5 equivalents of the acid chloride, in a small volume of the reaction-inert solvent, dropwise, with stirring, during about 10 to 20 minutes. At a temperature of about 0° to 25° C., the reaction takes about one to about four hours substantially to reach completion. At the end of the reaction, the reaction medium is partitioned between water and a volatile, water-immiscible, organic solvent. The organic solvent is removed, washed with water at pH 7.0 and with water at pH 3.5, and then dried. Removal of the solvent by evaporation in vacuo affords the compound of formula VIII. 
     A second convenient way of activating the carboxy group in a compound of the formula IX involves formation of a mixed anhydride. Mixed anhydride formation entails suspending or dissolving a carboxylate salt (e.g. the triethylamine salt) in a reaction-inert organic solvent (e.g. dichloromethane) and then adding about one molar equivalent of a hindered alkanoyl chloride (e.g. pivaloyl chloride) or a lower-alkyl chloroformate (e.g. ethyl chloroformate). The reaction is usually carried out at about 0° C., and it normally takes about 30 minutes to one hour to reach completion. Although the mixed anhydride can be isolated by solvent evaporation, it is usual simply to use it in situ for reaction with the amine of formula R 2  --NH 2 . In this case a solution of about one molar equivalent of the amine is added to the mixed anhydride solution, dropwise, at about 0° C. The reaction is allowed to proceed for about 30 minutes to one hour at about 0° to 25° C. If a water-immiscible solvent has been used, the product is isolated by washing the solvent with 1 N potassium hydroxide and with water. The solution is then dried and evaporated in vacuo to give the compound of formula VIII. If a water-miscible solvent has been used, the product can be isolated by removing the solvent by evaporation in vacuo, replacing it with a water-immiscible solvent, and then proceding as described above. 
     The compounds of formula IX, wherein Q is ##STR12## and R 5  is hydrogen and R 6  is selected from the group consisting of hydrogen and methyl, can be prepared by condensation of the appropriate nitrobenzaldehyde with a phosphorane of the formula ##STR13## followed by basic hydrolysis of the ethyl ester grouping. 
     The compounds of formula IX, wherein Q is ##STR14## and R 5  is methyl and R 6  is selected from the group consisting of hydrogen and methyl, can be prepared by reaction of the appropriate nitroacetophenone and a phosphonate compound of the formula ##STR15## in the presence of one equivalent of sodium hydride, followed by basic hydrolysis of the ethyl ester grouping. 
     Some of the compounds of formula IX are known (see further Baker et al., Journal of Medicinal Chemistry, 11, 672 [1968]), and some are commercially available. The compounds of formula X are either commercially available or known (see further Isler et al., Helvetica Chimica Acta, 40, 1242 [1957]). The compounds of formula XI are either commercially available or known (see further Arbusor et al., Chemische Berichte, 60, 291 [1927] and Chemical Abstracts, 23, 4444 [1929]). 
     The compounds of formula IX, wherein Q is ##STR16## are prepared by known methods, or methods analogous to known methods. 
     The compounds of formula I, wherein R 1  is alkyl, can be prepared by reaction of the corresponding compound of formula I, wherein R 1  is hydrogen, with the appropriate diazoalkane. In this case, the free acid is dissolved or suspended in a reaction-inert solvent, and then a slight excess of an ethereal solution of the diazoalkane is added. The reaction mixture is stirred at ambient temperature for about two to 24 hours, and then any excess diazoalkane is decomposed by the addition of a small amount of acetic acid. Removal of the solvent in vacuo affords the required compound of formula I, wherein R 1  is alkyl. Suitable solvents for this esterification procedure are those which do not adversely interact with either the starting material or the product, and from which the product can be recovered readily. Typical examples are chlorinated hydrocarbons, such as chloroform and dichloromethane; ethers, such as tetrahydrofuran, dioxane and 1,2-dimethoxyethane; and acetonitrile. 
     The compounds of formula I, wherein R 1  is --CH 2  CH 2  --NR 3  R 4  can be prepared from the corresponding compound of formula I, wherein R 1  is hydrogen, by esterification with a compound of the formula HO--CH 2  CH 2  --NR 3  R 4 . This reaction can be carried out conveniently by first activating the compound of formula I, wherein R 1  is hydrogen, by reaction with carbonyldiimidazole. The activated derivative is then reacted with the appropriate 2-(N,N-dialkylamino)ethanol. In a typical procedure, substantially equimolar quantities of a compound of formula I, wherein R 1  is hydrogen, and carbonyldiimidazole are reacted for a few minutes at about 60° to 70° C., in a reaction inert solvent such as tetrahydrofuran, and then one to two equivalents of the 2-(N,N-dialkylamino)ethanol are added. After a reaction time of about 15 to 30 minutes at about 60° to 70° C., the solvent is removed. The residue is dissolved in a water-immiscible, volatile solvent and the solution is washed with water and dilute sodium hydroxide, and then it is dried. Evaporation affords the compound of formula I, wherein R 1  is --CH 2  --CH 2  --NR 3  R 4 . 
     As will be appreciated by one skilled in the art, a compound of the formula I, wherein Q is ##STR17## can exist as one of two geometrical isomers, by virtue of the presence of the double bond to which the substituted phenyl and the CO--NHR 2  groups are attached. In one isomer the substituted phenyl group is on the opposite side of the double bond from the --CO--NHR 2  group (the trans-isomer); in the other isomer, the substituted phenyl group is on the same side of the double bond as the --CO--NHR 2  group (the cis-isomer). Both isomers, and mixtures thereof, are within the scope of this invention. However, the trans-isomers are preferred. Additionally, as will be appreciated by one skilled in the art, if it is desired to prepare a trans-isomer of the formula I, the synthetic sequence IX to VIII to VII to I is carried out starting with a compound of formula IX, in which the nitrophenyl and the carboxy groups are on opposite sides of the double bond from each other. Conversely, operation of the synthetic scheme IX to VIII to VII to I, starting with a compound of formula IX in which the nitrophenyl group and the carboxy group are on the same side of the double bond as each other, leads to the cis-isomer of the compound of formula I. 
     In the compounds of this invention in which Q is ##STR18## the two groups attached to the cyclopropane ring are always trans to each other. 
     The compounds of the formula I, wherein R 1  is hydrogen, are acidic and they form base salts. All such base salts are within the scope of this invention. They can be prepared by conventional methods for carboxylic acid compounds. For example, they can be prepared readily and conveniently simply by contacting the acidic and basic entities, usually in a stoichiometric ratio, in either an aqueous, non-aqueous or partially aqueous medium, as appropriate. The salts are recovered either by filtration, by precipitation with a non-solvent followed by filtration, by evaporation of the solvent, as appropriate, or, in the case of aqueous solutions, by lyophilization. Basic agents suitably employed in salt formation belong to both the organic and inorganic types, and they include ammonia, organic amines, alkali metal hydroxides, alkali metal carbonates, alkali metal bicarbonates, alkali metal hydrides, alkali metal alkoxides, alkaline earth metal hydroxides, alkaline earth metal carbonates, alkaline earth metal hydrides and alkaline earth metal alkoxides. Representative examples of such bases are primary amines, such as n-propylamine, n-butylamine, aniline, cyclohexylamine, benzylamine, p-toluidine and octylamine; secondary amines, such as diethylamine, N-methylaniline, morpholine, pyrrolidine and piperidine; tertiary amines, such as triethylamine, N,N-dimethylaniline, N-ethylpiperidine, N-methylmorpholine and 1,5-diazobicyclo[ 4.3.0]non-5-ene; hydroxides, such as sodium hydroxide; alkoxides, such as sodium methoxide and potassium methoxide; hydrides, such as calcium hydride and sodium hydride; and carbonates, such as potassium carbonate and sodium carbonate. 
     Additionally, the compounds of formula I, wherein R 1  is --CH 2  CH 2  --NR 3  R 4 , are basic and they will form acid-addition salts. All such acid-addition salts are within the scope of this invention. They can be prepared by conventional methods for tertiary amine compounds. For example, they can be prepared by contacting said compound of formula I, wherein R 1  is --CH 2  CH 2  --NR 3  R 4 , with a stoichiometric amount of the appropriate acid in an appropriate solvent. The salt can then be recovered by filtration, by precipitation with a non-solvent followed by filtration, or by evaporation of the solvent, as appropriate. Acid-addition salts of compounds of formula I, wherein R 1  is --CH 2  --CH 2  --NR 3  R 4 , can be prepared from both inorganic and organic acids, and typical salts are the hydrochloride, hydrobromide, hydroiodide, sulfate, bisulfate, phosphate, acetate, maleate, fumarate, oxalate, lactate, tartrate, citrate, gluconate and 4-toluenesulfonate. 
     As indicated hereinbefore, the compounds of formula I are of value as antagonists of the slow-reacting substance of anaphylaxis (SRS-A). This activity can be detected and evaluated by methods known in the art. In one method, the ability of a compound of formula I to antagonize SRS-A induced contractions in isolated guinea pig ileal muscle is measured. Terminal ileum segments, 2.5 cm. long, are removed from Reed-Willet guinea pigs, 350-450 g., and suspended in 10 ml. muscle baths containing Tyrode&#39;s solution (NaCl--136.9 mM, KCl--2.68 mM, CaCl 2  --1.8 mM, NaH 2  PO 4  --0.42 mM, MgCl 2  --2.0 mM, NaHCO 3  --11.9 mM, glucose--5.5 mM) saturated with 95% O 2  --5% CO 2  and maintained at 38° C. The tissue is attached by silk thread to a Statham force displacement transducer (FT 0.03) under 2 g. tension and muscle activity is recorded via a Grass Model 5 polygraph. For initial testing submaximal contractions to SRS-A (˜1 unit/ml.) are obtained in a total of six preparations (three from each of two animals). Each antagonist is added to all baths one minute prior to the addition of SRS-A at a concentration of 10 -4  M, and the percentage inhibition of contraction is measured. 
     The ability of the compounds of formula I to antagonize the effects of SRS-A makes them useful for inhibiting the symptoms induced by SRS-A in a human subject. The compounds are valuable therefore in the prevention and treatment of such disease states in which SRS-A is the causative factor, e.g. skin disorders, allergic rhinitis, and obstructive airways diseases. The compounds are particularly valuable in the prevention and treatment of allergic bronchial asthma. 
     A compound of formula I, or a pharmaceutically-acceptable salt thereof, can be administered to a human subject either alone, or, preferably, in combination with pharmaceutically-acceptable carriers or diluents, in a pharmaceutical composition, according to standard pharmaceutical practice. A compound can be administered orally or parenterally. Parenteral administration includes intravenous, intramuscular, intraperitoneal, subcutaneous and topical administration, and also administration by inhalation and insufflation. 
     In a pharmaceutical composition comprising a compound of formula I, or a pharmaceutically-acceptable salt thereof, the weight ratio of carrier to active ingredient will normally be in the range from 1:6 to 6:1, and preferably 1:2 to 4:1. However, in any given case, the ratio chosen will depend on such factors as the solubility of the active component, the dosage contemplated and the precise route of administration. 
     For oral use of an SRS-A antagonist of this invention, the compound can be administered, for example, in the form of tablets or capsules, or as an aqueous solution or suspension. In the case of tablets for oral use, carriers which are commonly used include lactose and corn starch, and lubricating agents, such as magnesium stearate, are commonly added. For oral administration in capsule form, useful diluents are lactose and dried corn starch. When aqueous suspensions are required for oral use, the active ingredient is combined with emulsifying and suspending agents. If desired, certain sweetening and/or flavoring agents can be added. For intramuscular, intraperitoneal, subcutaneous and intravenous use, sterile solutions of the active ingredient are usually prepared, and the pH of the solutions should be suitably adjusted and buffered. For intravenous use, the total concentration of solutes should be controlled to render the preparation isotonic. For administration by inhalation or insufflation, it is convenient to prepare an aqueous or partially aqueous solution of a compound of formula I or salt thereof, and then this solution is administered in the form of an aerosol. 
     When a compound of formula I or salt thereof is used as an SRS-A antagonist in a human subject, the daily dosage will normally be determined by the prescribing physician. Moreover, the dosage will vary according to the age, weight and response of the individual patient, as well as the severity of the patient&#39;s symptoms. However, in most instances, an effective daily dosage will be in the range from about 0.02 g. to about 1.0 g., and preferably 0.05 g. to 0.5 g., in single or divided doses. On the other hand, it may be necessary to use dosages outside these limits in some cases.
