Like sulfonylureas with reducing sugar content in the blood is known from patent application Belgium 754454 and unaccepted bids Germany 1198354. In applications for patents Germany P 4341655.1 (HOE 93/F 399) and P 4344957.3 (HOE 93/F 439) offer benzosulfimide and-thiourea, which, however, do not have the cyclo-group matching containing the Y ring.

There describe the reducing sugar content in the blood of the action of the sulfonylureas. The prototype of such reducing sugar content in the blood of the sulfonylureas is glibenclamide, which is used in therapy as a means dlsueac sensitive to ATP potassium channels. Along with reducing the sugar content in the blood by the action of glibenclamide has other actions that still could not be used in therapy, but all of which together amount to a blockade just those sensitive to ATP potassium channels. This includes especially directed against the atrial action on the heart. However, in the treatment of ventricular fibrillation of the heart or its preliminary stages simultaneously decreasing the amount of sugar in the blood would be undesirable or even dangerous, as it can worsen the condition of the patient.

Therefore, the present invention was to obtain compounds that have the same good effect on the heart as glibenclamide, but the sugar content in the blood is effective for heart doses or concentrations do not affect or influence significantly less than glibenclamide.

As experimental animals to confirm such actions are suitable, for example, mice, rats, Guinea pigs, rabbits, dogs, monkeys or pigs.

The compounds of formula I are used as active substances of medicinal products for human and veterinary medicine. Further, they can be used as intermediate products for the manufacture of other will acrobatyour:

R(1) - alkyl with 1, 2, 3 or 4 C-atoms,

R(2) - methoxy or ethoxy,

R(3) is hydrogen,

R(4), R(5) R(6) - independently from each other hydrogen, aryl or alkyl with 1, 2, 3, 4, 5, 6, C-atoms,

E - sulfur,

X is oxygen,

Y - CH2.

Especially preferred compounds of formula I, in which mean:

R(1) - alkyl, with 1, 2, 3 or 4 C-atoms,

R(2) - methoxy or ethoxy,

R(3) is hydrogen,

R(4) and R(5) independently from each other hydrogen, alkyl with 1, 2, 3, 4, 5, 6 C-atoms,

R(6) - aryl,

The compounds of formula I of this invention are valuable medicines to treat heart rhythm disorders of different Genesis and to prevent due to arrhythmia sudden death from cardiac arrest, and so they may find use as antiarrhythmic funds. Examples of arrhythmic heart disorders are supraselective arrhythmias, such as tachycardia fibrillation, atrial flutter or paroxysmal supraselective arrhythmias, or ventricular arrhythmias like ventricular extrasystole, but especially life-threatening ventricular tachycardia or especially dangerous Mercan the coronary vessel, as for example, angina or during acute myocardial infarction or appear as a consequence of chronic myocardial infarction. Therefore, they are used especially in postinfarction patients to prevent sudden death from cardiac arrest. Other clinical pictures, which play a role similar arrhythmias and/or sudden, caused by arrhythmia death from cardiac arrest, are, for example, heart failure or cardiac hypertrophy as a consequence of chronic high blood pressure.

In addition, the compounds of formula I can have a positive effect on the contractility of the heart. Thus we can talk about disease caused by the weakening of the contractility of the heart, for example, in case of insufficiency of the heart, but also about acute cases, as the fall of cardiac activity when exposed to shock. Similarly, when a heart transplant after the operation, the heart can be faster and more reliable again to resume its functional ability. The same applies to operations on the heart, which necessitates a temporary cardiac arrest due to cardioplegic solutions, and connections can be used to protect organs, Nacimiento.

The invention relates then to a production method of benzosulfimide formula I, which is characterized by the fact that benzosulfimide formula II

< / BR>
or its salt of the formula III

< / BR>
interacting with R(1) substituted by isothiocyanato formula VI

R(1) - N = C = S

where R(1), R(2), R(3), R(4), R(5), R(6), X, Y described above.

The cation M in the salts of the formula (III) take into account the ions of alkali and alkaline earth metals.

As the drying means, you can apply all appropriate to obtain the amide bonds of connection, such as dicyclohexylcarbodiimide, carbonimidoyl, anhydride propriospinal acid. As solvents are used inert nephratonia solvents, such as THF, QMF, simple, diethyl ether, dichloromethane, and mixtures of these solvents.

The compounds of formula I and their physiologically not cause fear salts are valuable therapeutic agents, which are suitable not only as antiarrhythmic funds, but also for the prevention during the disorders of the cardiovascular system, heart failure, heart transplant, or diseases of the blood vessels of the brain in humans or mammals (N. the state of fear salts of compounds of formulas I mean in Pharmaceutical science of Remmington, 17th edition, 1985, S. 14-18, compounds of formula X

< / BR>
which can be derived from nontoxic organic and inorganic bases and benzosulfimide formula I.

While I prefer salt in which M(1) in formula X are ions of sodium, potassium, rubidium, calcium, magnesium, and also addition products of acids, basic amino acids, such as lysine or arginine.

Starting compound for the above-mentioned synthesis methods of benzosulfimide formula I get the known methods described in the literature (for example, in basic writings, as Houben-Weyl. Methods of organic chemistry, Georg Thieme-Verlag, Stuttgart; Organic reactions, John Wiley & Sons, Inc., New York; and in the above patent applications, namely in terms of reactions, which are known and suitable for the mentioned transformations. You can use also known, but not mentioned here more options. The source of the substance, if necessary, can be formed also in place so that they are not isolated from the reaction mixture, and immediately turn on.

So, correspondingly substituted carboxylic acid of formula XI according to scheme 1 (see the end of the description) can pstway with the corresponding amines R(3), R(4), NH after activation of the carboxylic acid group to a carboxylic acid amide of formula II.

As methods of activation are applied to obtain the acid chloride of the carboxylic acid or mixed anhydrides, carboxylic acid halides of formic acid. You can then apply known to obtain the amide bonds of the reactants, as for example, carbonimidoyl, dicyclohexylcarbodiimide and anhydride propriospinal acid.

Obtained in scheme 1 as intermediate products sulfonamides of formula XII can interact with the corresponding isocyanates of the formula R(1) - N = C = E to carboxylic acids of benzosulfimide formula IX according to scheme 2 (see the end of the description).

The compounds of formula I may have one or more chiral centers. Therefore, when manufacturing them can be obtained as racemates or, if used optically active substances are also in optically active form. If the compounds have one or more chiral centers, they can get in the synthesis as mixtures of racemates, from which the individual isomers can be isolated in pure form, for example, by recrystallization from inert solvents. Separate the racemates, if required the houtem interaction with optically active dividing means it is possible to form diastereomers. As release agents for basic compounds are used, for example, optically active acids, as R - or R, R and S, respectively S,S - forms of tartaric acid, dibenzoyltartaric acid, diatsetilvinny acid, camphor sulphonic acids, almond acid, malic acid or lactic acid. Further, carbinol using chiral reagents acylation, for example, R - or S-methylbenzenesulfonate, you can lidirovat and then separate. Various forms of the diastereomers can in a known manner, for example, fractional crystallization, separating, and enantiomers of the formula I can in a known manner to release. The enantiomers could then be separated by chromatography on optically active substances-carriers.

Compounds according to the invention of the formula I and their physiologically not cause fear salts can be used for the manufacture of pharmaceutical preparations. They could, however, along at least one solid or liquid carrier or auxiliary substance, alone or in combination with other effective circulation with heart medicines such as calcium antagonists, NO-donors or ACE-inhibitors, bring in the proper dosage form. These products can be used when sportsouth organic or inorganic substances, suitable for intestinal (e.g. oral), parenteral, such as intravenous administration or for local applications, and which do not react with the new compounds, such as water, vegetable oils, benzyl alcohols, polyethylene glycols, glycerol triacetate, gelatin, carbohydrates as lactose or starch, magnesium stearate, talc, lanolin, petrolatum. For oral administration are especially tablets, coated tablets, capsules, syrups, juices or drops; for rectal use solutions, mainly oily or aqueous solutions, then suspensions, emulsions or implants; for topical application are ointments, creams, pastes, lotions, gels, sprays, foams, aerosols, solutions (for example, in alcohols as ethanol or isopropanol, acetonitrile, 1,2-propandiol or their mixtures with each other or with water) or powder. New connections can be subjected to lyophilization and apply lyophilizate, for example, for the manufacture of drugs for injection. In particular, for local use also use liposomal preparations, stabilizers and/or substances with a high surface activity, emulsifiers, salts and/or auxiliary substances, such as lubricants, preservatives, their substance. They can optionally also contain one or more other active substances, for example one or more vitamins.

The dosage required for the treatment of cardiac arrhythmias with compounds of the formula I depends on used for acute therapy or for prevention. Generally carry a range of doses of at least about 0.1 mg, mostly minimally 1 mg, up to a maximum of 100 mg, predominantly up to a maximum of 10 mg per 1 kg and 1 day, if prevention is conducted. Mainly the dose range is from 1 to 10 mg per 1 kg and 1 day in relation to an adult with an average weight of 75 kg, this dose can be divided into oral or parenteral single dose or four single doses. If you treat acute cases of cardiac arrhythmias, for example in a hospital, it may be beneficial to the parenteral administration. In this case, the preferred range of doses in critical situations can be from 10 to 100 mg, and the dose may be administered, for example, as prolonged intravenous infusion.
