The amidation of the compounds of the general formula (II) is in general carried out in inert solvents in the presence of a base and a dehydrating agent.

Suitable solvents in this connection are inert organic solvents which do not change under the reaction conditions. These include halogenated hydrocarbons such as dichloromethane, trichloromethane, tetrachloromethane, 1,2-dichloroethane, trichloroethane, tetrachloroethane, 1,2-dichloroethane or trichloroethylene, hydrocarbons such as benzene, xylene, toluene, hexane, cyclohexane, or mineral oil fractions, nitromethane, dimethylformamide, acetonitrile or hexamethylphosphoramide. It is also possible to employ mixtures of the solvents. Dichloromethane is particularly preferred.

Suitable bases for the amidation are the customary basic compounds. These preferably include alkali metal and alkaline earth metal hydroxides such as lithium hydroxide, sodium hydroxide, potassium hydroxide or barium hydroxide, alkali metal hydrides such as sodium hydride, alkali metal or alkaline earth metal carbonates such as sodium carbonate, potassium carbonate, or alkali metal alkoxides such as, for example, sodium methoxide or ethoxide, potassium methoxide or ethoxide or potassium tert.-butoxide, or organic amines such as benzyltrimethylammonium hydroxide, tetrabutylammonium hydroxide, pyridine, triethylamine or N-methylpiperidine.

The amidation is generally carried out in a temperature range from 0.degree. C. to 150.degree. C., preferably at 25.degree. to 40.degree. C.

The amidation is generally carried out at normal pressure. However, it is also possible to carry out the process at reduced pressure or at elevated pressure (for example in a range from 0.5 to 5 bar).

When carrying out the amidation, the base is generally employed in an amount from 1 to 3 moles, preferably from 1 to 1.5 moles, relative to 1 mole of the carboxylic acid of the general formula (II).

Suitable dehydrating reagents are carbodiimides such as, for example, diisopropylcarbodiimide, dicyclohexylcarbodiimide or N-(3-dimethylaminopropyl)-N'-ethylcarbodiimide hydrochloride or carbonyl compounds such as carbonyldiimidazole or 1,2-oxazolium compounds such as 2-ethyl-5-phenyl-1,2-oxazolium-3-sulphonate or propanephosphoric anhydride or isobutyl chloroformate or benzotriazolyloxy-tris-(dimethylamino)-phosphonium hexafluorophosphate or diphenyl phosphoramidate or methanesulphonyl chloride, if appropriate in the presence of bases such as triethylamine or N-ethylmorpholine or N-methylpiperidine or dicyclohexylcarbodiimide and N-hydroxysuccinimide [cf. J. C. Sheehan, S. L. Ledis, J. Am. Chem. Soc. 95, 875 (1973); F. E. Frerman et al., J. Biol. Chem. 225, 2199, (1980) and N. B. Benoiton, K. Kuroda, Int. J. Pept. Prot. Res. 13, 403 (1979), 17, 187 (1981)].

The sulphonation of the compounds of the general formula (IV) is carried out in the abovementioned inert solvents, if appropriate using the bases and dehydrating agents also mentioned above.

The sulphonation is generally carried out at normal pressure. However, it is also possible to carry out the process at reduced pressure or elevated pressure (for example in a range from 0.5 to 5 bar).

The sulphonation is generally carried out in a temperature range from 0.degree. C. to 150.degree. C., preferably from +25.degree. C. to +40.degree. C.

The compounds of the general formula (III) are known or can be prepared by customary methods [cf. Houben-Weyl, "Methoden der organischen Chemie" (Methods of Organic Chemistry), volume IX, p. 407 ff and J. March, Advanced Organic Chemistry, Second Edition (1977) [cf. J. March, "Advanced Organic Chemistry", Second Edition p. 824 ff. (1977)].

The compounds of the general formulae (II) and (IV) are new and can be prepared, for example, by etherifying compounds of the general formulae (VI) or (VII) ##STR9## in which

R.sup.1 and R.sup.2 have the abovementioned meanings,

R.sup.6 represents hydroxyl, C.sub.1 -C.sub.6 -alkoxy or phenyloxy, and

Y represents a typical hydroxyl protective group, such as, for example, benzyl or tert. butyl, after removal of the protective group by the customary method, with halomethylquinolines of the general formula (VIII) ##STR10## in which A, B, D, E, L and G are identical or different and have the abovementioned meanings and

Z represents halogen in inert solvents, if appropriate in the presence of a base or in the case of the compounds of the formula II in addition by alkylating compounds of the formula (IX) ##STR11## wherein A, B, D, E, L and G have the abovementioned meanings

and

R.sup.6' has the abovementioned meaning of R.sup.6 but does not represent hydroxy,

directly with compounds of the formula (X)

wherein

R.sup.1 has the abovementioned meaning

and

y represents halogen, preferably bromine,

and in the case of the acids hydrolyzing the esters.

The removal of the protective groups from the corresponding ethers is carried out by the customary method, for example, by hydrogenolytic cleavage of the benzyl ethers in the abovementioned inert solvents with hydrogen gas in the presence of a catalyst [cf. also Th. Greene: "Protective Groups in Organic Synthesis", J. Wiley & Sons, 1981, New York].

The etherification can be carried out in inert organic solvents, if appropriate in the presence of a base.

Solvents for the etherification may be inert organic solvents which do not change under the reaction conditions. These preferably include ethers such as, for example, dioxane, tetrahydrofuran or diethyl ether, halogenated hydrocarbons such as dichloromethane, trichloromethane, tetrachloromethane, 1,2-dichloroethane or trichloroethylene, hydrocarbons such as benzene, xylene, toluene, hexane, cyclohexane or mineral oil fractions, nitromethane, dimethylformamide, acetonitrile, acetone or hexamethylphosphoramide. It is also possible to employ mixtures of the solvents.

Bases which can be employed for the etherification are inorganic or organic bases. These preferably include alkali metal hydroxides such as, for example, sodium hydroxide or potassium hydroxide, alkaline earth metal hydroxides such as, for example, barium hydroxide, alkali metal carbonates such as sodium carbonate or potassium carbonate, alkaline earth metal carbonates such as calcium carbonate, or organic amines (trialkyl(C.sub.1 -C.sub.6 C)amines) such as triethylamine, or heterocycles such as pyridine, methylpiperidine, piperidine or morpholine.

It is also possible to employ alkali metals such as sodium, and their hydrides, such as sodium hydride, as bases.

The etherification is generally carried out in a temperature range from 0.degree. C. to 150.degree. C., preferably from 10.degree. C. to 100.degree. C. at normal pressure. However, it is also possible to carry out the etherification at reduced pressure or elevated pressure (for example in a range from 0.5 to 5 bar).

The hydrolysis of the carboxylic acid esters is carried out by customary methods by treating the esters in inert solvents with customary bases, it being possible to convert the salts initially formed into the free carboxylic acids by treating with acid.

Suitable bases for the hydrolysis are the customary inorganic bases. These preferably include alkali metal hydroxides or alkaline earth metal hydroxides such as, for example, sodium hydroxide, potassium hydroxide or barium hydroxide, or alkali metal carbonates such as sodium carbonate or potassium carbonate or sodium hydrogencarbonate or alkali metal alkoxides such as sodium ethoxide, sodium methoxide, potassium ethoxide, potassium methoxide or potassium tert.butoxide. Sodium hydroxide or potassium hydroxide are particularly preferably employed.

Suitable solvents for the hydrolysis are water or the organic solvents customary for hydrolysis. These preferably include alcohols such as methanol, ethanol, propanol, isopropanol or butanol, or ethers such as tetrahydrofuran or dioxane, or dimethylformamide or dimethyl sulphoxide. Alcohols such as methanol, ethanol, propanol or isopropanol are particularly preferably used. It is also possible to employ mixtures of the solvents mentioned.

The hydrolysis is generally carried out in a temperature range from 0.degree. C. to +100.degree. C., preferably from +20.degree. C. to +80.degree. C.

In general, the hydrolysis is carried out at normal pressure. However, it is also possible to work at reduced pressure or at elevated pressure (for example from 0.5 to 5 bar).

When carrying out the hydrolysis, the base is generally employed in an amount from 1 to 3 moles, preferably from 1 to 1.5 moles, relative to 1 mole of the ester. Molar amounts of the reactants are particularly preferably used.

When carrying out the reaction, the salts of the compounds according to the invention are formed in the first step as intermediates which can be isolated. The acids according to the invention are obtained by treating the salts with customary inorganic acids. These preferably include mineral acids such as, for example, hydrochloric acid, hydrobromic acid, sulphuric acid or phosphoric acid. In this connection, it has proved advantageous in the preparation of the carboxylic acids to acidify the basic reaction mixture from the hydrolysis in a second step without isolating the salts. The acids can then be isolated in a customary manner.

The alkylation of the C-H acid compounds (formula IX) with alkyl halides is in general carried out in inert solvents in the presence of a base.

Suitable solvents for this reaction are all the inert organic solvents, depending on the nature of the alkylating agent. These solvents include, preferably, ethers, such as diethyl ether, dioxane or tetrahydrofuran, or hydrocarbons, such as benzene, toluene or xylene, or dimethylformamide or hexamethylphosphoric acid triamide, or mixtures of the solvents mentioned.

Suitable bases are the customary basic compounds. These include, preferably, alkali metal hydrides, such as sodium hydride, alkali metal amides, such as sodium amide or lithium diisopropylamide, alkali metal alcoholates, such as sodium methanolate, sodium ethanolate, potassium methanolate, potassium ethanolate or potassium tert.-butylate, or organic amines, such as trialkylamines, for example triethylamine, or organolithium compounds, such as butyllithium or phenyllithium.

The alkylation of the CH-acid compounds is in general carried out in a temperature range from 0.degree. C. to 150.degree. C., preferably from 10.degree. C. to 100.degree. C.

The alkylation of the CH-acid compounds is in general carried out under normal pressure. However, it is also possible to carry out the process under reduced pressure or increased pressure (for example in a range from 0.5 to 5 bar).

In general, 0.5 to 5, preferably 1 to 2, mol of halide are employed per mol of the reaction partner. The base is in general employed in an amount of 0.5 to 5 mol, preferably 1 to 3 mol, based on the halide.

The compounds of the general formulae (VI) and (VII) are known per se or can be prepared by known methods [cf. H. Beyer, Lehrbuch der organischen Chemie (Textbook of Organic Chemistry), S. Hirzel Verlag, Stuttgart; Protective Groups in Organic Synthesis, J. Wiley & Sons, 1981, New York].

The halomethylquinolines of the general formula (VIII) are known or can be prepared by the customary method [cf. Chem. Ber.,120, 649, 1987].

The compounds of the general formula (X) are known. The compounds of the general formula (IX) are known or can be prepared by customary methods.

In order to prepare isomerically pure compounds of the general formula (I), the isomerically pure form of the starting compound can of course be employed directly. However, they can also be obtained by the customary methods of racemate separation.

The acylsulphonamides and acylcyanamides of the general formula (I) according to the invention can be employed as active compounds in medicaments. The compounds act particularly as inhibitors of enzymatic reactions in the context of arachidonic acid metabolism, in particular lipoxygenase.

They are thus suitable preferably for the treatment and prevention of disorders of the airways such as allergies/asthma, bronchitis, emphysema, shock lung, pulmonary hypertension, inflammations/rheumatism and oedemas, thromboses and thromboembolisms, ischaemias (peripheral, cardiac and cerebral circulatory disturbances), cardiac and cerebral infarcts, cardiac arrhythmias, angina pectoris, arteriosclerosis, in tissue transplants, dermatoses such as psoriasis, metastases and for cytoprotection in the gastrointestinal tract.

The pharmacological activity data of the substances according to the invention are determined by the following method:

As a measure of the lipoxygenase inhibition, the release of leucotriene B.sub.4 (LTB.sub.4) from polymorphonuclear rats leucocytes (PMNL) was determined after addition of substances and Ca ionophore by means of reverse phase HPLC according to Borgeat, P. et al., Proc. Nat. Acad. Sci., 76, 2148-2152 (1979). The in vivo activity of the compounds was detected using the mouse ear inflammation model according to Young, J. M. et al., J. of Investigative Dermatology, 82, 367-371 (1984).

In Table 1, the values obtained by this test for some compounds according to the invention are shown by way of example: ______________________________________ Example    LO inhibition IC.sub.50 (mmol/l) ______________________________________ 1          2.7 .times. 10.sup.-8 6          3.3 .times. 10.sup.-8 7          2.4 .times. 10.sup.-8 ______________________________________

Using suitable inert non-toxic, pharmaceutical excipients or solvents, the new active compounds can be converted in a manner known per se into the customary formulations, such as tablets, capsules, coated tablets, pills, granules, aerosols, syrups, emulsions, suspensions and solutions. In this connection, the therapeutically active compound should in each case be present in the total mixture in a concentration of about 0.5 to 90% by weight, preferably from 10 to 70% by weight, i.e., in amounts which are sufficient in order to achieve the dosage range indicated.

The formulations are prepared, for example, by extending the active compounds with solvents and/or excipients, if appropriate using emulsifiers and/or dispersants, where, for example, in the case of the use of water as a diluent, if appropriate organic solvents can be used as auxiliary solvents.

Examples of auxiliaries which may be mentioned are: water, non-toxic organic solvents such as paraffins (for example, mineral oil fractions), vegetable oils (for example, groundnut/sesame oil), alcohols (for example, ethyl alcohol, glycerol), glycols (for example, propylene glycol, polyethylene glycol), solid excipients, such as ground natural minerals (for example, kaolins, clays, talc, chalk), ground synthetic minerals (for example, highly disperse silica, silicates), sugars (for example, sucrose, lactose and dextrose), emulsifiers (for example, polyoxyethylene fatty acid esters, polyoxyethylene fatty alcohol ethers, alkylsulphonates and arylsulphonates), dispersants (for example, lignin-sulphite waste liquors, methyl cellulose, starch and polyvinylpyrrolidone) and lubricants (for example, magnesium stearate, talc, stearic acid and sodium lauryl sulphate).

Administration can be carried out in a customary manner, preferably orally or parenterally, in particular perlingually or intravenously. In the case of oral administration, tablets can of course also contain additions such as sodium citrate, calcium carbonate and dicalcium phosphate together with various additives, such as starch, preferably potato starch, gelatin and the like in addition to the excipients mentioned. Furthermore, lubricants such as magnesium stearate, sodium lauryl sulphate and talc can additionally be used for tableting. In the case of aqueous suspensions and/or elixirs, which are intended for oral administration, various flavor-improvers or colorants can be added to the active compounds in addition to the abovementioned auxiliaries.

For the case of parenteral administration, solutions of the active compounds can be employed using suitable liquid excipients.

In general, it has proved advantageous on intravenous administration to administer amounts of about 0.01 to 10 mg/kg, preferably about 0.01 to 5 mg/kg of body weight, to attain effective results. On oral administration, the dosage is in general about 0.1 to 200 mg/kg, preferably 1 to 100 mg/kg of body weight.

In spite of this it may be necessary to deviate from the amounts mentioned, depending on the body weight or type of application route, on individual behavior towards the medicament, the manner of its formulation and the point in time or interval at which administration takes place. Thus, in some cases it maybe sufficient to manage with less than the minimum amount previously mentioned, while in other cases the upper limit mentioned must be exceeded. In the case of the administration of relatively large amounts, it may be advisable to divide these into a number of individual doses over the day.

The acylsulphonamides and acylcyanamides according to the invention can be used both in human medicine and in veterinary medicine.
