BACKGROUND of the INVENTION

Congestive heart failure (CHF) is a disease that affects approximately 2% of the population of the United States (Sami, M.H. [1991] J.Clin.Pharmacol.31:1081). Despite advances in diagnosis and treatment of CHF prognosis remains poor, with a mortality rate within 5 years from the date of diagnosis is greater than 50% (McFate Smith, W. [1985] Am.J.Cardiol. 55:3A; McKee, P.A., W.P.Castelli, P.M. McNamara, W.B.Kannel [1971] N.Engl.J.Med.285:1441). Among patients with CHF the lowest survival was observed in those patients who have strongly suppressed the function of the left ventricle, as well as in patients with frequent ventricular arrhythmias. In patients with ventricular arrhythmias and ischemic cardiomyopathy there is an increased risk of sudden death. The presence of ventricular tachycardia in patients with severe CHF leads to a threefold increase in the frequency of sudden death compared to patients who do not have tachycardia (Bigger, J.T., Jr. [1987] Circulation 75 (suppl.IV):28). Due to the significant prevalence of sudden unexpected death in patients with CHF, there is a growing interest in the reliability prediction of arrhythmias in these patients.

Several of the compounds used in the treatment of cardiac arrhythmias in patients with congestive heart failure. Unfortunately, antiarrhythmic drug therapy has been disappointing. The effectiveness of antiarrhythmic Leka is the only means significantly decreases left ventricular function, so only a small proportion of patients with CHF respond to antiarrhythmic treatment. Does not exist antiarrhythmic drugs capable of preventing sudden death in patients with CHF, and even had a question about the increased mortality associated with certain antiarrhythmic agents (the CAST investigators [1989] N.Engl.J.Med.321:406).

Scientists determine tachycardia and ventricular fibrillation as a phenomenon of multiple nature. Now was clear and made in the technique that the mechanism underlying the most sustainable types of arrhythmia, is the circulation of excitation. Therefore, revived the interest in increasing the duration of ventricular repolarization as a means of prevention of ventricular fibrillation. This gives grounds to consider drug class-III as the preferred drugs for the treatment of arrhythmias. The funds referred to in this application by means of class-III, are funds that are assigned to this class in the classification of antiarrhythmic drugs Vaughan-Williams. Class-III showing his primary antiarrhythmic effect by increasing the duration of action potential (APD) of the heart muscle and, thereby, the effective refractory period (ERP), without affecting the conductivity. These electrophysiological changes, the reason is which is the blockade of cardiac potassium channels, well known in the art. Because blockade of cardiac potassium channels is not associated with the suppression of myocardial contractility, class-III are particularly interesting for use in patients with CHF. Unfortunately, existing tools class III limited from the point of view of their applicability to additional types of pharmacological activity, lack of bioavailability for oral use or poor toxicity profile. Two means of class-III, which are currently available commercially are bretylium (only intravenously) and amiodarone (intravenous and oral).

Amiodarone is an antiarrhythmic agent with vasodilating properties, which can be useful for patients with severe heart failure. It was shown that amiodarone improves the survival rate of post-infarction patients with asymptomatic life-threatening ventricular arrhythmias, in addition, proved the effectiveness of this tool in patients resistant to other complications, without deterioration of left ventricular function. For use in patients with coronary insufficiency have been described cardiotoxin means and ways in which amiodarone is used in synergistic combination with vasodilator means and beta-blockers (U.S. patent No. 5175187). In addition to the CSO, described the use of amiodarone in combination with antihypertensive agents, such as (S)-1-[6-amino-2-[hydroxy(4-phenylbutyl)phosphinyl]oxyl]-L-Proline (U.S. patent No. 4962095) and zofenoprilat (U.S. patent No. 4931464)to reduce arrhythmia associated with CHF. However, the use of amiodarone as a drug is hampered by numerous side effects, some of which are dangerous.

The reason most dangerous long-term toxicity of amiodarone is the kinetics of distribution and elimination. It is absorbed slowly, with low bioavailability and relatively long half-life. These characteristics have clinically significant consequences, including the need to introduce shock doses, delay achieving the full antiarrhythmic action and a prolonged period of introduction of the drug after withdrawal.

In addition, amiodarone may adversely interact with many drugs, including aprindine, digoxin, flecainide, phenytoin, procainamide, quinidine, and warfarin. He also has a pharmacodynamic interaction with catecholamines, diltiazem, propanolol and quinidine, leading to alpha - and beta antagonism, stop the sinus node and hypotension, bradycardia and stop the sinus node, as well as bi-directional which corresponds ventricular tachycardia and ventricular tachycardia, respectively. In addition, there is evidence that amiodarone inhibits the vitamin K-dependent coagulation factors, thereby improving anticoagulation effect of warfarin.

Numerous side effects limit the clinical applicability of amiodarone. Can have significant side effects, including microclone in the cornea, gipertireoidizmom, hypothyroidism, liver dysfunction, pulmonary alveolitis, photosensitivity dermatitis, bluish in color, and peripheral neuropathy.

Currently on the market there are no drugs-class III, which can be safely applied to patients with CHF. The market for cardiovascular drugs is the largest in the whole area of study drugs, and effective and safe antiarrhythmic agent of class-III, which can be used by patients with CHF is expected to bring significant benefits. Therefore, the drug, which could successfully improve the prognosis in patients with CHF, but with significantly better compared with amiodarone safety profile, it would be extremely useful and desirable. Various analogues of amiodarone have been described previously (U.S. patent№ 6372783; 6362223; 6316487; 6130240; 5849788; 5440054 and 5364880). The present invention adds to the Arsenal of connections.

In particular, the methods of obtaining and purification of these stereoisomeric compounds. Ways of introduction into the molecule of such ester fragments, as well as obtaining and purification of stereoisomers are well known to the specialist in the art and can be easily implemented using the guidelines outlined in this application.

DEFINITIONS AND conventions

Below are definitions and explanations of terms used throughout the text of this document, including the description and the claims.

I. legend in formulas and variable definitions

Chemical formulas representing the various compounds or molecular fragments in the description and the claims, in addition to right particular structural fragments can contain variables deputies. These variable substituents are identified by a letter or a letter followed by a numerical subscript or Superscript notation, for example “Z1”, or “Z1”, or “Ri”where “i” indicates an integer. These variable substituents are either monovalent or bivalent. I.e. they represent the groups attached to the rest of the molecule one or two chemical bonds. An ordinary person skilled in the art it should be clear from the context, one or two links present in a particular case. For example, the group Z1could be a divalent Deputy, as, for example, in the structure of CH3-C(=Z1)H. In another example, the group Riand Rjwould represent monovalent variable substituents, as in the structure of CH3-CH2-C(Ri)(Rj)H. If the structure is shown in linear form, as in the above cases, variables deputies, placed in parentheses, associated with the atom, which is directly to the left of the bracketed Deputy. If in brackets there are two or more coming one after another substituent, each of the consecutive variable substituents bound to the atom, standing directly (i.e. first) to the left of the brackets. For example, in the above formula, both Deputy Riand Rjassociated with the preceding carbon atom. In addition, for any molecule with an established system of numbering of carbon atoms, such as steroids, these carbon atoms are marked as Ciwhere “i” is an integer corresponding to the number of carbon atom. For example, C6means 6 position the tion or the number of carbon atoms in the steroid nucleus according to the traditional designation, adopted from experts in the field of steroid chemistry. “Ci” can refer to the i-th carbon atom or to a fragment containing the “i” of carbon atoms. The meaning of the use of this designation in a particular case should be clear to an ordinary person skilled in the technical field of the context in which used the symbol.

Chemical structures or fragments thereof, shown in a linear form, represent the atoms in a straight chain. The characters “--“ and “-“usually means a bond between two atoms in the chain. So CH3--O--CH2--CH(Ri)--CH3and CH3-O-CH2-CH(Ri)-CH3and combinations “--“ and “-“ in these formulas represent the 2-substituted-1-methoxypropan. In addition, a linear mapping patterns can be cast without character relations “-” and/or “-”. For example, the formula CH3OCH2CH(Ri)CH3also displays the 2-substituted-1-methoxypropan. Similarly, the symbol “=” indicates a double bond, for example CH2=C(Ri)--O--CH3and the symbol “≡” displays a triple bond, such as CH≡C-CH(Ri)--CH2--CH3. Carbonyl group, usually displayed in one of four ways: CO, C(O)C(=O) or C=O, surrounding communication “--“ can be either shown or not shown, with the first two ways images are preferred in the Lu their simplicity. The numbers that follow immediately after the atoms in chemical formulas or their fragments, displayed either a normal or an inferior font, mean number of previous atoms or groups of atoms, as in the usual practice of chemistry. For example, both refer to a “C1-C8 alkyl” and “C1-C8alkyl describe the alkyl fragment comprising from 1 to 8 carbon atoms.

Hard cyclic (ring) structure for all connections in this application determines the orientation of the substituents attached to each of the carbon atoms of such cyclic compounds, relative to the plane of the loop. For saturated compounds in which the carbon atom that is part of a cyclic system, attached two Deputy, ie --C(X1)(X2)--these two substituent may be either axial or Equatorial position relative to the cycle, and can also change the position between the axial and Equatorial. However, the position of the two substituents relative to the cycle and relative to each other remains constant. Although any of the deputies from time to time may be in the plane of the loop (Equatorial position), and not above or below this plane (axial position), one of the substituents is always above the other relative to the plane of the loop, depicted in a particular ori is ncacii. In the chemical structural formulas depicting such compounds, a substituent (X1), which is "below" another substituent (X2), is defined as the Deputy located in the alpha (α) configuration, and is shown in the text broken, dashed or dotted line going to the carbon atom, i.e. the symbol “- - -“ or “...”. The appropriate Deputy (X2) "above" the others (X1), named in the text of the substituent in the beta (β) configuration and is shown as a solid line going to the carbon atom. In the following example, the Deputy X1is "under" X2: if X1is Equatorial, X2located axially, up from the plane of the loop, leaving the plane of the paper in the direction of view of 2-dimensional patterns. An alternative example is when X2is Equatorial, X1located axially down from the plane of the loop in the plane of the paper and in the direction opposite to the direction of view of 2-dimensional patterns.

If AC Deputy is divalent, if a particular variable Deputy these valence can be used together, separately, or both at once. For example, a variable substituent Riattached to the carbon atom in the fragment-C(=Ri)-could be two alentum and in this case could be defined as oxo or ketogroup (hence, the fragment would be a carbonyl group (-CO-)or could be defined as two separately attached monovalent variable substituent α-Ri-jand β Ri-kwhere “i” identifies a specific group R and “j” and “k” define a specific group Ri. When the bivalent variable substituent Ridefined in such a way that it consists of two monovalent variable substituents, a designation used to refer to two monovalent substituents, has the form “α-Ri-jand β Ri-k” or any of its variants. In this case, both Deputy α-Ri-jand β Ri-kattached to the carbon atom forming the fragment-C(α-Ri-j)(β-Ri-k)-. For example, if it is determined that the bivalent variable substituent R6in the fragment-C(=R6)consists of two monovalent variable substituents, the two monovalent variable Deputy represent α-R6-1: β-R6-2and form the fragment-C(α-R6-1)(β-R6-2)-. Likewise, for the bivalent variable substituent R11in the snippet --C(=R11)-- the designation of two monovalent variable substituents are α-R11-1: β-R11-2. In the case of cyclic substituent, in which there is no separate α and β orientations (for example, due to the presence in the cycle double carbon-carbon is due), and for Vice-related carbon atom that is not part of the cycle, still using the above symbol, but letter symbols α and β are omitted.

Just as the bivalent variable Deputy can be defined as two separate monovalent variable Deputy, and two separate monovalent variable substituent can be defined as together forming a divalent AC Deputy. For example, in formula C1(Ri)H-C2(Rj)H- (C1and C2arbitrarily defined as the first and second carbon atoms, respectively) Ri and Rj can be defined as jointly forming (1) a second bond between C1and C2or (2) a bivalent group such as oxa (-O-), and in this case, the above formula describes the epoxides.

The number of carbon atoms in variable substituents are shown as follows: the number of carbon atoms in each component of the definition is shown separately by enclosing them in brackets denote “Ci-Cj” and placing it in front of the part of the General definition of the Deputy, which defines the symbol. According to this first symbol C2-C4alkoxycarbonyl describes a group CH3-(CH2)nO-CO-, where n represents one, two or three. Similarly, although both denote C2-C6alkoxyalkyl and (C1-C3)alkoxy(C1-C3)alkyl define CNS group containing from 2 to 6 carbon atoms, the two definitions differ since the first one allows for the presence of 4 or 5 carbon atoms in the alkoxy or alkyl portion Deputy, whereas the second definition limits the number of carbon atoms in any of these groups the number 3.

If the fragment is included mandatory heteroatoms (the inclusion of the term "hetero" without parentheses) or optional heteroatoms (the inclusion of the term "hetero" in parentheses, such as(hetero)"), preferably numbering reflects the replacement of the existing carbon atom in the fragment of the heteroatom. So, although in General the reference to "C6of alkyl" includes linear, branched or cyclic alkyl radicals with up to six carbon atoms, "C6heteroalkyl" (or "C6(hetero)alkyl"), which includes a heteroatom, contains in this example five carbon atoms and a heteroatom, which was replaced by another carbon atom.

It should be understood that the use in the present description of the singular includes both the singular and the plural.

Prophylactic use is aimed at preventing the disease in the subject, which is threatened by the possibility of getting sick one or more of those mentioned in this application disorders. Thus, in the present description, the term "treatment" or its derivatives involve the partial or total suppression pointed to by the th morbid state if the active ingredient of the present invention is administered prophylactically or following the onset of painful conditions, to combat which impose such active ingredient. The term "prevention" refers to the introduction of active ingredient (ingredients) to a mammal to protect the latter from any of the above in this application, as well as other disorders.

The term "therapeutically effective amount" refers to the amount necessary to achieve the derived therapeutic effect, such as reduction or elimination of arrhythmic events or reduce their severity or duration.

The term "individual" ("individuals") is defined as an individual mammal, which is administered compounds of the present invention. The mammal can be, for example, mouse, rat, pig, horse, rabbit, goat, cow, cat, dog or man. In a preferred aspect, the individual is human.

Radical and its variant, replaced by a heteroatom (for example, aryl and heteroaryl; and "hetero" Deputy includes one or more heteroatoms, t is such as, for example, N, O, S and P), can be mentioned together with the aid of the bracketed prefix (hetero). For example, the term "(hetero)aryl" refers to aryl and the heteroaryl radical corresponding to the above definitions. Further, because the definition of each radical are also optional substituents and, where necessary, specify a linear, branched and/or cyclic in nature (for example, (hetero)alkyl and (hetero)alkanniny and other radicals can be linear, branched or cycloalkyl/cycloalkenyl), references (hetero)radicals (e.g., "(hetero)aryl and(hetero)alkyl") refers to radicals which optionally contain one or more heteroatoms, and in appropriate cases, may have a linear, branched and/or cyclic the character (and their combinations described in the text). Similarly, descriptions of the chemical groups comprising combinations of (hetero)radicals (e.g., "(hetero)alkyl(hetero)aryloxyalkyl")may indicate a combination of any of the typical characteristics of each radical, which were described earlier. Thus, a fragment of(hetero)alkyl(hetero)aryloxyalkyl" may refer to, for example, optionally substituted, linear, branched and/or cyclic (hetero)alkyl substituted, optionally substituted (hetero)aryloxy arborina fragment. Since (hetero)aryl radicals are optionally substituted as specified in their definition, may be present one or more additional substitutions in addition to specifically specified substitution (substitution) (hetero)alkyl. As an additional example, mention serial combinations of the same radical (for example, (hetero)alkyl(hetero)alkyloxy) also apply to all combinations of each of the radicals. For example, the name of the (hetero)alkyl(hetero)alkyloxy radical can be treated as one of many examples, branched, alkyl substituted, heterocyclic, alkyloxy the radical. However, the name of the (hetero)alkyl(hetero)alkyloxy radical may also include, as one of many examples of the linear alkyl substituted heterocyclic, alkyloxy the radical. For example, each of "(hetero)alkyl" radicals in the group "(hetero)alkyl(hetero)alkyloxy" may have different characteristics from one or more heteroatoms or absence of heteroatoms to alkyl chains of different lengths, and linear, branched or cyclic character, etc. similarly, using the previous example, each of the (hetero)alkyl radicals may have the same General characteristics. For example, the name of the (hetero)alkyl(hetero)alkyloxy radical may refer to heterocyclic alkyl substituted heterocyclic, alkyloxy the radical. However, the term "heterocyclic alkyl substituted heterocyclic, alkyloxy radicals" covers more than one type (for example, C6compared to C8heterocyclic alkyl Deputy). Thus, although the General characteristics of consecutive radicals with the same names can be the same as in example going prior to this, specific chemical identify each of the radicals need not be the same.

In addition, for functional groups of radicals can be used combinations of these terms. Typically, the last term in the name refers to the radical, which is linked to the rest of the chemical structure. For example, the term "halogenated" refers to the alkyl radical, substituted with halogen, the term "cycloalkenyl" refers to the alkyl radical, substituted by cycloalkyl, and the term "alkylsilanes" refers to cycloalkyl the radical, substituted by alkyl.

For simplicity, the chemical fragments define and mention mainly as a univalent chemical fragments (e.g., alkyl, aryl etc). However, under certain circumstances, a clear to a person skilled in the field of technology, these terms are used to indicate corresponding multivalent particles. For example the EP, while the name "alkyl" fragment, usually refers to a monovalent group (for example, CH3-CH2-), in certain circumstances, the bivalent binding fragment can be "alkyl", and in this case, the specialist in the art will understand that the alkyl is a divalent group (for example, -CH2-CH2-), which corresponds to the term "alkylene". (Similarly, in those situations where the presence of divalent fragment and confirmed that this fragment is the "aryl", the specialist in the art will understand that the term "aryl" relates to the corresponding bivalent fragment, i.e arylene). Have in mind that all atoms are normal for them the number of valences for the formation of ties (i.e. 4 for carbon, 3 for N, 2 for O, and 2, 4, or 6 for S, depending on the oxidation state of the S).

EXAMPLES

It is considered that a person skilled in the art using the preceding description, without additional testing methods implements the present invention in practice, in its entirety. In the following detailed examples describe how to get a variety of compounds (i.e. compounds covered by formula (1)to(4), and compounds covered by formula (5), which are derived from compounds of the formulas (1)to(4)and/or implement various techniques for infusion is he to the invention, and these examples should be interpreted only as illustrative and in nowise limiting the foregoing disclosure of the invention. Specialist in the art will quickly find the appropriate changes described methods both in terms of reagents and the conditions and methods of conducting reactions.

Obtaining new compounds of the present invention is shown in the following example, which, however, is not intended to serve as a limitation for these new connections.

In the example in the text descriptions of the reactions can be referred to specific amounts of reactants or "mass parts" and "molar fractions". Mention "mass parts" and "molar fractions" describe, for example, the mass and the stoichiometric ratio between the applied reaction reagents based on arbitrarily prescribed standard. For example, in the reaction, which requires the use of 36 g (approximately 2 moles) of water, water can be selected as the basic reagent. Because the amount of water taken as a starting point, the amount introduced into the reaction water in grams and moles can be defined as, for example, 1 mass part or 1× molar fraction. Thus, in the example of this paragraph 36 g of water are defined as one mass part and 2 mol of water is defined as 1× molar fraction. The selection of a basic reagent to separate reacts and or scheme of the reaction is completely arbitrary, as the selection of base quantities mass parts and molar fractions, and in this application for each of these options is selected the number "1".

Hereinafter amounts of reactants can be specified with respect to water or any other selected basic reagent. For example, the application of 400 g (4,55 mol) of ethyl acetate (mol. weight=88 g) can be described as 400/36 g or 11.1 mass parts and 4,55 mol/2 mol or of 2.27× molar fractions.
