Antithrombotic iso- and heterocyclic phenylsulphonamides

Abstract

Iso- and heterocyclic phenylsulphonamides can be prepared by reaction of corresponding iso- and heterocyclic amines with phenylsulphonic acid derivatives. The iso- and heterocyclic phenylsulphonamides have thrombocyte aggregation-inhibiting and thromboxane A.sub.2 antagonist action and can be used in medicaments.

Description

The invention relates to iso- and heterocyclic phenylsulphonamides, to a process for their preparation and to their use in medicoments, in particular as antithrombotics.

It is already known that some chroman derivatives have a hypotensive action [compare DE-OS (German Published Specification) 3,411,993]. In addition, substituted aminomethyl-5,6,7,8-tetrahydronaphthyl-oxyacetic acids having an antithrombotic, antiatherosclerotic and antiischaemic action are described in DE-A1 3,642,105. Furthermore, bicyclic chroman derivatives having thrombocyte aggregation-inhibiting action are described in DOS 3,737,195.

Thrombosis and arteriosclerotic vascular changes are controlled in particular by the metabolism of two metabolites of arachidonic acid, namely thromboxane A.sub.2 (TXA.sub.2) and prostacyclin (PGI.sub.2). TXA.sub.2 has an aggregating effect on the blood platelets and PGI.sub.2 has an antiaggregating effect. Moreover, TXA.sub.2 acts as a vasoconstrictor and bronchoconstrictor and PGI.sub.2 as a vasodilator and bronchodilator.

In a number of thromboembolic and ischaemic disorders, hyperaggregability of the platelets or elevated platelet consumption leads to an increased thromboxane synthesis, so that the TXA.sub.2 and PGI.sub.2 equilibrium is disturbed. It is therefore desirable for the therapy and prophylaxis of thromboembolic and ischaemic disorders to inhibit the effect of thromboxane and thus to increase the protective property of PGI.sub.2.

The invention relates to iso- and heterocyclic phenylsulphonamides of the general formula (I) ##STR1## in which A, B, D and E are identical or different and

represent hydrogen, hydroxyl, halogen, trifluoromethyl, trifluoromethoxy, straight-chain or branched alkyl or alkoxy in each case having up to 8 carbon atoms, or represent aryl having 6 to 10 carbon atoms, which is optionally monosubstituted to trisubstituted by identical or different substituents from the series comprising halogen, trifluoromethyl, trifluoromethoxy, carboxyl, nitro, cyano or by straight-chain or branched alkyl, alkoxy or alkoxycarbonyl in each case having up to 8 carbon atoms, or represent a group of the formula --(CH.sub.2).sub.m --CO--Z or --O--(CH.sub.2).sub.p --CO--Z, wherein m denotes a number 0, 1, 2, 3 or 4, p denotes a number 1, 2, 3 or 4, and Z denotes hydroxyl, straight-chain or branched alkoxy having up to 8 carbon atoms, aryloxy having 6 to 10 carbon atoms or a group of the formula --NR.sup.4 R.sup.5, wherein R.sup.4 and R.sup.5 are identical or different and denote hydrogen, straight-chain or branched alkyl having up to 8 carbon atoms or aryl having 6 to 10 carbon atoms, with the proviso that either A and B or B and D or D and E together must form a 5- to 7-membered saturated or unsaturated carbocycle fused to the basic structure or a heterocycle having up to 4 heteroatoms from the series comprising nitrogen, oxygen, sulphur or a group --NR.sup.6, wherein R.sup.6 denotes hydrogen, straight-chain or branched alkyl having up to 8 carbon atoms, aryl having 6 to 10 carbon atoms or a group of the formula --(CH.sub.2).sub.p --CO--Z, wherein p and Z have the abovementioned meanings, and which in turn may be substituted by a group of the formula --(CH.sub.2).sub.m --CO--Z or --O--(CH.sub.2).sub.p --CO--Z, wherein m, p and Z have the abovementioned meanings, Y represents the group --(CH.sub.2).sub.s --, wherein s denotes a number 0, 1, 2, 3 or 4, R.sup.1 represents aryl having 6 to 10 carbon atoms, which is optionally monosubstituted to pentasubstituted by identical or different substituents from the series comprising halogen, cyano, nitro, trifluoromethyl, difluoromethyl, difluoromethoxy, trifluoromethoxy, carboxyl, aryloxy having 6 to 10 carbon atoms, by straight-chain or branched alkyl, alkoxy or alkoxycarbonyl in each case having up to 8 carbon atoms or by the group --NR.sup.4 R.sup.5, wherein R.sup.4 and R.sup.5 have the abovementioned meanings, n represents a number 0, 1 or 2, R.sup.2 and R.sup.3 are identical or different and represent hydrogen, straight-chain or branched alkyl or alkoxy in each case having up to 8 carbon atoms, represent a group of the formula --(CH.sub.2).sub.m --CO--Z or --NR.sup.4 R.sup.5, wherein m, Z, R.sup.4 and R.sup.5 have the abovementioned meanings, X represents oxygen or the --CH.sub.2 -- group, and their salts.

In this connection, the therapeutically active compound should in each case be present in a concentration from about 0.5 to 90% by weight, preferably from 5 to 70% by weight, relative to the preparation, which is sufficient in order to achieve the dosage range indicated.

USE EXAMPLE

In order to determine the thrombocyte aggregation-inhibiting action, blood from healthy subjects of both sexes was used. One part of 3.8% strength aqueous sodium citrate solution was added to 9 parts of blood as an anticoagulant. Platelet-rich citrate plasma (PRP) was obtained from this blood by means of centrifugation (Jurgens/Beller, Klinische Methoden der Blutgerinnungsanalyse (Clinical Methods of Blood Coagulation Analysis); Thieme Verlag, Stuttgart, 1959).

For these investigations 0.8 ml of PRP and 0.1 ml of the active compound solution were preincubated at 37.degree. C. in a waterbath. The thrombocyte aggregation was then determined at 37.degree. C. in an aggregometer (Therapeutische Berichte 47, 80-86, 1975) by the turbidometric method (Born G.V.R., J. Physiol. (London), 162, 67, 1962). For this purpose, 0.1 ml of collagen, an aggregation-inducing agent, was added to the preincubated sample. The change of the optical density in the sample of PRP was recorded for a period of 6 minutes and the aggregation was determined after 6 minutes. For this purpose, the percentage inhibition compared to the control is calculated. The threshold concentration is indicated by the range of the minimum effective concentration.

The threshold concentrations are between 0.003-10 mg/l, for example compound of Example 73. EC=0.03-0.01 mg/l.

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

Auxiliaries which may be mentioned are, for example: 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, ethylene glycol), solid excipients, such as, for example, ground natural minerals (for example kaolins, clays, talc, chalk), ground synthetic minerals (for example highly disperse silicic acid, 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, methylcellulose, starch and polyvinylpyrrolidone) and lubricants (for example magnesium stearate, talc, stearic acid and sodium laurylsulphate).

Administration can take place in a customary manner, preferably orally or parenterally, in particular perlingually or intravenously. In the case of oral administration, tablets may of course also contain additions, such as sodium citrates, 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 laurylsulphate and talc can additionally be used for tabletting. In the case of aqueous suspensions and/or elixirs which are intended for oral administration, various flavor enhancers or colorants may also be added to the active compounds in addition to the abovementioned auxiliaries.

In 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 0.001 to 1 mg/kg, preferably about 0.01 to 0.5 mg/kg of body weight to attain effective results. On oral administration, the dosage is in general about 0.01 to 20 mg/kg, preferably 0.1 to 10 mg/kg of body weight.

However, it may be advantageous to deviate from the amounts mentioned, depending on the body weight or the 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 may be 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 larger amounts, it may be advisable to divide these into a number of individual doses over the day.

B) Preparation Examples (formula I)

General procedure

10 ml of the amine (see Examples 64-78) are refluxed in 20 ml of absolute THF together with 10 ml of the corresponding sulphonyl chloride and 25 mmol of anhydrous potassium carbonate until the reaction is complete (TLC checking, 6-24 h). The mixture is evaporated, and the residue is partitioned between 50 ml of ethyl acetate and 100 ml of 1N HCl solution and stirred until all solids are dissolved. After phase separation, the ethyl acetate phase is shaken once each with 1N HCl, saturated NaHCO.sub.3 solution and saturated NaCl solution, dried over Na.sub.2 SO.sub.4 and evaporated. If required, the residue can be further purified by flash chromatography. The residue is dissolved in 30 ml of methanol and 10 ml of 3N KOH solution are added. If esters are present, the mixture is stirred at room temperature for 2-4 h, and in the case of amides it is refluxed for 6-8 h. The methanol is evaporated off, and the KOH phase is washed with methylene chloride and brought to pH 1-2 using concentrated HCl solution with ice cooling. Products obtained as solids are filtered off, and with oily products the mixture is extracted twice with ethyl acetate. After drying in a high vacuum, the compounds are pure. The compounds are compiled in the following tables.

The complete .sup.1 H-NMR spectra are in each case only indicated once for each basic structure. After this, only the signals of the different benzenesulphonamide groups are indicated. In order to, distinguish the final products, the example numbers are additionally provided with the Roman numeral I (corresponds to general formula I).
