Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The invention concerns aminodesoxy-1.4;3.6-dianhydrohexitol nitrates of the general formula I, ##STR2## wherein R.sup.1 and R.sup.2, each independently of one another, signify a hydrogen atom or a lower alkyl group with 1 to 4 C-atoms or wherein R.sup.1 signifies a hydrogen atom or a lower alkyl group with 1 to 4 C-atoms and R.sup.2 an acyl radical of an aliphatic or singly unsaturated, possibly methyl-substituted monocarboxylic acid with 2 to 8 C-atoms, a nicotinoyl, 2-O-acetylsalicoyl radical or a 1-adamantyl radical, or wherein R.sup.1 signifies a hydrogen atom and R.sup.2 a 2-hydroxy-3-(subst.)-phenoxyprop-1-yl radical of the general formula Ia ##STR3## wherein R.sup.3 signifies a hydrogen atom, a lower alkyl or lower alkenyl group with 1 to 4 C-atoms, the trifluoromethyl radical, a hydroxyl group, a lower alkoxy or lower alkenyloxy group with 1 to 4 C-atoms, a cyano group or a carbamoylmethyl radical, or wherein R.sup.1 signifies a hydrogen atom and R.sup.2 a 2-hydroxy-3-(.alpha.-naphthyloxy)-prop-1-yl radical, whereby the ring of the naphthalene structure not etherified with the hydroxypropyl group can be wholly or partially hydrogenated or substituted by an oxo group, or wherein R.sup.1 signifies a hydrogen atom or a lower alkyl group with 1 to 4 C-atoms and R.sup.2 an .omega.-(subst.)-phenylalkyl group of the general formula Ib ##STR4## wherein n can be=a whole number from 1-6 and R.sup.4 and R.sup.5, each independently of one another, signify a hydrogen atom, a lower alkyl or alkenyl group with 1 to 4 C-atoms, the trifluoromethyl radical, a hydroxyl group, a lower alkoxy or lower alkenyloxy group with 1 to 4 C-atoms or a fluorine or chlorine atom, or wherein R.sup.1 signifies a hydrogen atom or a lower alkyl group with 1 to 4C-atoms and R.sup.2 the diphenylmethyl radical or cinnamyl radical, or wherein R.sup.1 signifies a hydrogen atom or a lower alkyl group with 1 to 4 C-atoms and R.sup.2 an .omega.-(subst.)-phenoxyalkyl group of the general formula Ic ##STR5## wherein m can be=a whole number of 2-8 and R.sup.6 and R.sup.7, independently of one another, a hydrogen atom, a lower alkyl or lower alkenyl group with 1 to 4 C-atoms, the trifluoromethyl radical, a hydroxyl group, a lower alkoxy or lower alkenyloxy group with 1 to 4 C-atoms, a fluorine or chlorine atom, the amino or acetylamino group, a mono- or di-lower alkylamino group with 1 to 4 C-atoms or R.sup.6 and R.sup.7, together with the phenyl radical, form the .alpha.-naphthyl radical, or wherein R.sup.1 and R.sup.2, together with the nitrogen atom to which they are attached, represent the radical of a cyclic, non-aromatic, secondary amine with 5 to 7 ring atoms, possibly containing a further hetero atom, or wherein R.sup.1 and R.sup.2 together signify the pyridoxylidene radical, as well as their pharmacologically acceptable acid-addition salts.

The basic structure of these compounds consists of one of the stereoisomeric 1.4;3.6-dianhydrohexitols, convertible into one another by epimerisation, namely, either 1.4:3.6-dianhydro-L-iditol (="isoidide") (II), ##STR6## in which the OH groups in the 2- and 5-position each have the exo-configuration, or 1.4;3.6-dianhydro-D-glucitol (="isosorbide") (III) ##STR7## which has a 2-exo-standing and a 5-endo-standing OH group and thus--in the case of different substituents in the 2- and 5-position--occurs in two isomeric forms.

Finally, the basic structure of some compounds consists of 1.4;3.6-dianhydro-D-mannitol (="isomannide") (IV), ##STR8## which has two endo-standing OH groups.

Since, in contradistinction to the glucitol derivatives, in the case of the iditol and mannitol derivatives a difference between the 2- and 5-substituents is not possible because the C.sup.2 -atom, in the case of rotation of the molecule through 180.degree., becomes the C.sup.5 -atom, references to the 5-position or 2-position of substituents are superfluous in the case of these compounds. However, for a better comparison of the structures of the individual compounds with the general formulae, the isoidide derivatives are here always referred to as 5-aminoisoidide derivatives since they result from the isosorbide derivatives acyl-substituted in the 5-position. Correspondingly, the isomannide acyl derivatives employed as starting compounds are referred to as 2-acylisomannide derivatives since they are prepared from isosorbide derivatives substituted in the 2-position.

2. Description of the Prior Art

A brief summary regarding the stereoisomerism of the 1.4;3.6-dianhydrohexitols is given by J. A. Mills in Advances in Carbohydrate Chem., 10, 1-53 (1955).

The invention also concerns processes for the preparation of the initially-mentioned aminodesoxy-1.4;3.6-dianhydrohexitol nitrates, as well as pharmaceutical compositions which contain the compounds according to the invention.

The nitrates of 1.4;3.6-dianhydro-D-glucitol (also called 1.4;3.6-dianhydro-D-sorbitol) are known e.g. from U.S. patent specification No. 3,886,186, namely, not only the 2- and 5-mononitrates but also the 2,5-dinitrates of isosorbide. These nitrates, especially the dinitrate, which are already commercially available as medicaments, are pharmacologically active substances with haemodynamic, vasodilatory and antianginous effectiveness which are especially employed in the case of coronary insufficiency and for the treatment of angina pectoris.

The pharmacokinetics of the dinitrate and of the mononitrates of isosorbide, isomannide and isoidide have been described by Bogaert and Rosseel in Naunyn-Schmiedeberg's Arch. Pharmacol., 275, 339 (1972).

However, it has been shown that the nitrates cause unpleasant side effects, especially headaches. Furthermore, the mononitrates are more poorly resorbed than, for example, isosorbide dinitrate (ISDN). It is also to be added that the dinitrates of isosorbide, isomannide and isoidide can only be prepared and handled with special precautionary measures because they are explosive.

SUMMARY OF THE INVENTION

Thus, a need existed for the making available of new pharmaceutical agents with the same activity spectrum but which do not display the mentioned disadvantages and for the provision of new 1.4;3.6-dianhydrohexitol mononitrates which can be used as effective components of such pharmaceutical agents.

The task forming the basis of the invention consists in satisfying the stated need, the solution of this problem in the making available of the materials according to the invention.

Consequently, the subject of the invention are

1. N-substituted 5-amino-5-desoxy-1.4;3.6-dianhydro-L-iditol 2-nitrates, as well as the N-unsubstituted 5-amino-5-desoxy-1.4;3.6-dianhydro-L-iditol 2-nitrate of the general formula V, ##STR9## wherein R.sup.1 and R.sup.2 possess the meanings mentioned in claim 1, as well as their physiologically acceptable acid-addition salts; 2. the correspondingly N-substituted 5-amino-5-desoxy-1.4;3.6-dianhydro-D-glucitol 2-nitrates, as well as the N-unsubstituted 5-amino-5-desoxy-1.4;3.6-dianhydro-D-glucitol 2-nitrate of the general formula VI, ##STR10## as well as their physiologically acceptable acid-addition salts; 3. the correspondingly N-substituted 2-amino-2-desoxy-1.4;3.6-dianhydro-D-glucitol 5-nitrates and the N-unsubstituted 2-amino-2-desoxy-1.4;3.6-dianhydro-D-glucitol 5-nitrate of the general formula VII, ##STR11## as well as their physiologically acceptable acid-addition salts; 4. the correspondingly N-substituted 5-amino-5-desoxy-1.4;3.6-dianhydro-D-mannitol 2-nitrates and the N-unsubstituted 5-amino-5-desoxy-1.4;3.6-dianhydro-D-mannitol 2-nitrate of the general formula VIII, ##STR12## as well as their physiologically acceptable acid-addition salts.

The compounds according to the invention possess coronary flowthrough-increasing, spasmolytic, blood pressure-lowering, negatively inotropic and heart frequency-lowering effectiveness. They are suitable for the treatment of coronary diseases, for the treatment and prophylaxis of angina pectoris attacks, for the post-treatment of heart infarcts and for the treatment of heart insufficiencies. The new compounds possess a good therapeutic range. The oral absorption is especially good and the period of action long. Furthermore, they bring about an improvement of the peripheral blood flow and of the brain blood flow.

The handling and preparation of the compounds according to the invention is much less dangerous than, for example, in the case of the known ISDN, because they are not explosive.

The compounds according to the invention possess four asymmetric C-atoms in the 1.4;3.6-dianhydrohexitol basic structure and are present in optically-active form since optically pure 1.4;3.6-dianhydrohexitols are used as starting compounds, which are easily obtainable from naturally-occurring sugar alcohols.

The compounds according to the invention can be prepared starting from the epimeric unsubstituted 1.4;3.6-dianhydrohexitols, thus starting from L-isoidide, D-isosorbide and D-isomannide, whereby, in the case of D-isosorbide as starting compound, several different synthesis routes are possible.

According to the invention, one of these routes consists in that the corresponding 1.4;3.6-dianhydrohexitol is converted with a sulphonic acid chloride, especially with methanesulphonic acid chloride or toluenesulphonic acid chloride, in a suitable anhydrous solvent and in the presence of an adjuvant base, preferably in pyridine or in chloroform/triethylamine, at a reduced temperature, preferably between -20.degree. and +10.degree. C., into the corresponding mono-O-acyl-1.4;3.6-dianhydrohexitol which is then, by the addition of an aqueous, for example 25%, ammonia solution or by the addition of a primary or secondary alkylamine with 1 to 4 C-atoms or of a primary amine, such as, for example, 1-aminoadamantane, or of a cyclic, non-aromatic secondary amine, subjected to an ammonolysis or aminolysis namely, advantageously under elevated pressure, preferably at a pressure of 2-20 ats., and elevated temperature, preferably at 90.degree. to 180.degree. C. The ammonolysis or aminolysis is expediently carried out in a closed steel autoclave, possibly with the addition of a suitable solvent, such as e.g. ethanol, butanol or dioxan, up to quantitative reaction.

DESCRIPTION OF THE PREFERRED EMBODIMENT

In the case of the ammonlysis or aminolysis to the corresponding possibly N-substituted aminodesoxy-1.4;3.6-dianhydrohexitol, the mesylate or tosylate group is exchanged for the amino or the correspondingly substituted amino group according to the reaction mechanism of a typical bimolecular nucleophilic substitution (S.sub.N 2 reaction), which always involves a reversal of configuration on the central carbon atom. This reversal of configuration, which is also known to the expert by the terms "inversion" or "Walden inversion", is the reason why, from the 1.4;3.6-dianhydro-D-glucitol 5-acyl derivative, in which the acyl radical is present endo-standing in the 5-position, there is always formed the 1.4;3.6-dianhydro-L-iditol derivative substituted in the 5-position by the amino group or the corresponding substituted amino group, in which the substituent entering into the molecule in place of the acyl radical no longer stands in the endo- but rather in the exo-position. The Walden inversion involved in the S.sub.N 2 reaction is, in a completely corresponding manner, responsible for the fact that from the corresponding iditol acylate there is always formed the glucitol derivative endo-substituted in the 5-position, from the mannitol acylate the corresponding glucitol derivative exo-substituted in the 2-position and from the glucitol 2-exo-acylate, the corresponding mannitol derivative endo-substituted in the 2-position.

The possibly N-substituted aminodesoxy-1.4;3.6-dianhydrohexitols resulting in the course of the hitherto described first synthesis route have a free hydroxyl group in the 2- or 5-position of the 1.4;3.6-dianhydrohexitols. This free hydroxyl group is esterified with nitric acid, nitrating acid or with a mixture of nitric acid and glacial acetic acid/acetic anhydride in the presence of urea at a reduced temperature, preferably at -20.degree. to 0.degree. C., to give the corresponding aminodesoxy-1.4;3.6-dianhydrohexitol mononitrate, whereby, instead of the aminodesoxy-1.4;3.6-dianhydrohexitol in the form of the free base, a suitable acid-addition salt, for example the corresponding salt of methanesulphonic acid, nitric acid or sulphuric acid, can also be used for the esterification.

The so formed mononitrate can, in the case of the N-unsubstituted or N-monoalkyl-substituted aminodesoxy-1.4;3.6-dianhydrohexitol nitrate, subsequently be condensed in per se known manner with an acid chloride, with pyridoxal, with benzyl chloride or a suitable possibly phenyl-substituted phenylalkyl halide or phenylalkylmethanesulphonate, with a possibly phenyl-substituted 1,2-epoxy-.omega.-phenoxyalkane or with a possibly phenyl-substituted 1-halo- or 1-methanesulphonyloxy-.omega.-phenoxyalkane to give the desired compound according to the invention, preferably with the addition of a suitable solvent and possibly of an adjuvant base or in the presence of an excess of the corresponding aminodesoxy-1.4;3.6-dianhydrohexitol nitrate.

For the preparation of those compounds according to the invention of general formula I, wherein R.sup.1 signifies hydrogen and R.sup.2 a lower alkyl group with 1 to 4 C-atoms or the 1-adamantyl radical, the corresponding 1.4;3.6-dianhydrohexitol acylate, e.g. 1.4;3.6-dianhydro-D-glucitol 2- or 5-methanesulphonate, 1.4;3.6-dianhydro-D-mannitol 2-methanesulphonate or 1.4;3.6-dianhydro-L-iditol 5-methanesulphonate, is subjected to the aminolysis with primary or secondary alkylamines with 1 to 4 C-atoms or with 1-aminoadamantane, namely, preferably under elevated pressure, preferably at a pressure of 2-20 ats., and elevated temperature, preferably at 90.degree. to 180.degree. C., and possibly in the presence of a solvent, preferably of ethanol, butanol, dioxan or glycol diethers. The aminolysis is expediently carried out in a closed steel autoclave up to quantitative reaction.

The aminolysis takes place with reversal of configuration of the substituted carbon atom so that, for example, from the 1.4;3.6-dianhydro-D-glucitol 2-methanesulphonate there results the N-mono- or -dialkyl- substituted 2-amino-2-desoxy-1.4;3.6-dianhydro-D-mannitol, from the 1.4;3.6-dianhydro-D-glucitol 5-methanesulphonate the corresponding N-substituted 5-amino-5-desoxy-1.4;3.6-dianhydro-L-iditol, from the 1.4;3.6-dianhydro-D-mannitol 2-methanesulphonate the 2-amino-2-desoxy-1.4;3.6-dianhydro-D-glucitol derivative and from the 1.4;3.6-dianhydro-L-iditol 5-methanesulphonate the 5-amino-5-desoxy-1.4;3.6-dianhydro-D-glucitol derivative.

As primary or secondary amines, there can be used e.g. methylamine, ethylamine, propylamine, isopropylamine, butylamine, isobutylamine, tert.-butylamine, dimethylamine, diethylamine, dipropylamine, dibutylamine, methylethylamine, methylpropylamine etc.

Subsequent to the aminolysis, the free hydroxyl group of the corresponding N-mono- or N-disubstituted aminodesoxy-1.4;3.6-dianhydrohexitol is esterified in the previously described per se known manner with nitric acid.

For the preparation of those compounds according to the invention of general formula I, wherein R.sup.1 and R.sup.2, together with the nitrogen atom to which they are attached, represent the radical of a cyclic, non-aromatic secondary amine with 5 to 7 ring atoms and possibly containing a further hetero atom, the corresponding 1.4;3.6-dianhydrohexitol acylate--also with reversal of configuration--is subjected to the aminolysis with secondary cyclic non-aromatic amines, for example, with pyrrolidine, piperidine, hexamethyleneimine, morpholine, 4-methylpiperazine etc., whereby the reaction is advantageously carried out, as described above, under elevated pressure and elevated temperature in a steel autoclave. The so prepared cyclic aminodesoxy-1.4;3.6-dianhydrohexitol derivatives are subsequently esterified on their free hydroxyl group with nitric acid completely analogously to the previously described manner.

For the preparation of those compounds according to the invention of general formula I, wherein R.sup.1 signifies a hydrogen atom or a lower alkyl group and R.sup.2 an acyl radical of an aliphatic or singly unsaturated, possibly methyl-substituted monocarboxylic acid, a nicotinoyl or 2-O-acetylsalicoyl radical, one reacts the corresponding, possibly N-alkyl-substituted amino-isohexide nitrate with, for example, acetyl chloride, propionyl chloride, butyryl chloride, n-valeroyl chloride, isovaleroyl chloride, caproyl chloride, pivaloyl chloride, nicotinic acid chloride hydrochloride or O-acetylsalicyclic acid chloride.

For the preparation of those compounds according to the invention of general formula I, wherein R.sup.1 signifies a hydrogen atom or a lower alkyl group and R.sup.2 the diphenylmethyl radical, the cinnamyl radical or an .omega.-(subst.)-phenylalkyl radical of the general formula Ib, the corresponding possibly N-alkyl-substituted aminoisohexide nitrate is reacted with compounds such as e.g. bromodiphenylmethane, cinnamyl bromide, benzyl chloride, phenylethyl bromide, phenylpropyl bromide, phenylbutyl bromide, phenylpentyl bromide, 3-(3,4-dimethoxyphenyl)-propyl 1-methanesulphonate, 4-(4-methoxyphenyl)-butyl-1-methanesulphonate, 4-(4-chlorophenyl)-butyl 1-methanesulphonate or 3-(4-chlorophenyl)-propyl 1-methanesulphonate etc.

For the preparation of those compounds according to the invention of general formula I, wherein R.sup.1 signifies a hydrogen atom or a lower alkyl group and R.sup.2 an .omega.-phenoxyalkyl group, the corresponding possibly N-alkyl-substituted aminoisohexide nitrate is reacted with compounds such as e.g. 2-phenoxy-1-bromoethane, 3-phenoxy-1-bromopropane, 4-phenoxy-1-bromobutane, 5-phenoxy-1-bromopentane, 6-phenoxy-1-bromohexane, 7-phenoxy-1-bromoheptane, 8-phenoxy-1-bromooctane.

For the preparation of those compounds according to the invention of general formula I, wherein R.sup.1 signifies a hydrogen atom and R.sup.2 a 2-hydroxy-3-(subst.)-phenoxyprop-1-yl radical of general formula Ia or a 2-hydroxy-3-(subst.)-naphthyloxyprop-1-yl radical, the corresponding aminoisohexide nitrate is reacted in per se known manner with compounds such as 1,2-epoxy-3-(4-methoxyphenoxy)-propane, 1,2-epoxy-3-(3-methoxyphenoxy)-propane, 1,2-epoxy-3-(2-methoxyphenoxy)-propane, 1,2-epoxy-3-(2-ethoxyphenoxy)-propane, 1,2-epoxy-3-(2-allyloxyphenoxy)-propane, 1,2-epoxy-3-(2-allylphenoxy)-propane, 1,2-epoxy-3-(2-cyanophenoxy)-propane, 1,2-epoxy-3-(3-tolyloxy)-propane, 1,2-epoxy-3-(3-trifluoromethylphenoxy)-propane, 4-(2,3-epoxypropoxy)-phenylacetic acid amide, 1,2-epoxy-3-(1-naphthyloxy)-propane, 5-(2,3-epoxypropoxy)-1-tetralone, 5-(2,3-epoxypropoxy)-tetralin.

For the preparation of those compounds according to the invention of general formula I, wherein R.sup.1 signifies a hydrogen atom or a lower alkyl group and R.sup.2 an .omega.-phenoxy-alkyl group of general formula Ic with substituted phenyl radical or an .omega.-naphthyloxyalkyl group, the corresponding possibly N-lower-alkyl-substituted aminoisohexide nitrate is reacted with compounds such as 3-(3-trifluoromethylphenoxy)-1-bromopropane, 3-(4-tolyloxy)-1-bromopropane, 3-(4-fluorophenoxy)-1-bromopropane, 3-(1-naphthyloxy)-1-bromopropane, 3-(4-methoxyphenoxy)-1-bromopropane, 3-(3-methoxyphenoxy)-1-bromopropane, 3-(2-methoxyphenoxy)-1-bromopropane, 3-(2,6-dimethoxyphenoxy)-1-bromopropane, 3-(3,5-dimethoxyphenoxy)-1-bromopropane, 3-(2,3-dimethoxyphenoxy)-1-bromopropane, 3-(4-chlorophenoxy)-1-bromopropane, 3-(2-chlorophenoxy)-1-bromopropane, 3-(3-chlorophenoxy)-propyl 1-methanesulphonate, 3-(3,4-dichlorophenoxy)-propyl 1-methanesulphonate, 3-(2,4-dichlorophenoxy)-propyl 1-methanesulphonate, 3-(4-acetamidophenoxy)-1-bromopropane, 3-(3-dimethylaminophenoxy)-propyl 1-methanesulphonate.

For the preparation of those compounds according to the invention of general formula I, wherein R.sup.1 and R.sup.2 together signify the pyridoxylidene radical, one condenses the corresponding aminodesoxy-1.4;3.6-dianhydrohexitol nitrate with pyridoxal, namely, advantageously in a suitable solvent or solvent mixture, e.g. ethanol, benzene, toluene or a mixture of these solvents, so that the resultant water of reaction can easily be removed by azeotropic distillation and an almost quantitative reaction can be achieved.

As follows from the above description of the process according to the invention for the preparation of the compounds according to the invention of general formula I, for the preparation of 5-amino-5-desoxy-1.4;3.6-dianhydro-L-iditol 2-nitrate, as well as of its N-mono- and N-disubstituted derivatives of the general formula V, as substrate of the ammonlysis or aminolysis, one must always employ the corresponding 1.4;3.6-dianhydro-D-glucitol 5-acylate, for example the 5-methanesulphonate or 5-toluenesulphonate, whereas for the preparation of 5-amino-5-desoxy-1.4;3.6-dianhydro-D-glucitol 2-nitrate as well as of its N-mono- and N-disubstituted derivatives of the general formula VI, one must always employ, as substrate for the ammonolysis or aminolysis, the corresponding 1.4;3.6-dianhydro-L-iditol 5-acylate, for example the 5-methanesulphonate or 5-toluenesulphonate.

Completely analogously, for the preparation of 2-amino-2-desoxy-1.4;3.6-dianhydro-D-glucitol 5-nitrate, as well as of its N-mono- and N-disubstituted derivatives of general formula VII, as substrate for the ammonolysis or aminolysis, one must always employ the corresponding 1.4;3.6-dianhydro-D-mannitol 2-acylate, for example the 2-methanesulphonate or 2-toluenesulphonate, whereas for the preparation of 5-amino-5-desoxy-1.4;3.6-dianhydro-D-mannitol 2-nitrate, as well as of its N-mono- and N-disubstituted derivatives of the general formula VIII, as substrate for the ammonolysis or aminolysis, one must use the corresponding 1.4;3.6-dianhydro-D-glucitol 2-acylate, for example the 2-methanesulphonate or 2-toluenesulphonate, whereafter, in the previously described manner, there follows the esterification with nitric acid and thereafter possibly the desired further substitution of the amino nitrogen by acylation with the corresponding acid chlorides or the further condensation with the corresponding reactive arylalkyl, aryloxyalkyl or aryloxy-epoxypropyl derivatives or with pyridoxal.

The previously described first route according to the invention for the preparation of the compounds according to the invention, in which the corresponding isohexide is converted with a sulphonic acid chloride, preferably with methanesulphonic acid chloride or toluenesulphonic acid chloride, into the corresponding monoacyl-1.4;3.6-dianhydrohexitol, has the disadvantage that, in the case of the acylation, not only does the corresponding 5-O-acyl derivative or 2-O-acyl derivative arise but simultaneously also the 2,5-diacyl derivative so that, in the case of the isoidide and isomannide derivatives, in each case the monoacyl compound must be separated from the diacylate, whereas in the case of the isosorbide, in which two stereoisometric monoacyl derivatives are formed besides the diacylate, the desired acylate must be isolated from the mixture of the three acyl derivatives. The separation of the acylate mixture takes place either by fractional crystallisation, fractional extraction or with the help of other per se known methods.

The laborious and time-consuming separation of the acylate mixture disappears, however, in the case of the use of the second synthesis route according to the invention to give the 5-aminoisoidide derivatives in that 1.4;3.6-dianhydro-D-glucitol is reacted quantitatively with an excess of sulphonic acid chloride, preferably methanesulphonyl chloride or toluenesulphonyl chloride, in pyridine or chloroform/triethylamine, to give the corresponding 1.4;3.6-dianhydro-D-glucitol 2,5-diacylate.

The diacylate is then subjected, under appropriate conditions, as described in the case of the first synthesis route, to the ammonolysis or aminolysis, whereby, as a result of the preferred substitution of the 5-endo-acyl group, with reversal of configuration, and as a result of partial hydrolysis of the 2-exo-acyl group, with maintenance of the configuration, besides a small amount of 2,5-diamino-2,5-didesoxy-1.4;3.6-dianhydro-D-glucitol remaining in the aqueous phase, there results a mixture of 5-amino-5-desoxy-1.4;3.6-dianhydro-L-iditol and 5-amino-5-desoxy-1.4;3.6-dianhydro-L-iditol 2-methanesulphonate in a ratio of about 1:4.

For the completion of the hydrolysis of the 2-exo-acyl group, this 1:4 mixture is then subjected to an alkaline or acidic hydrolysis and the resultant 5-amino-5-desoxy-1.4;3.6-dianhydro-L-iditol is subsequently, as described in the case of the first synthesis route, esterified to the corresponding mononitrate and possibly--completely analogously--by condensation with the corresponding acyl chlorides, .omega.-(subst.)-arylalkyl halides or methanesulphonates, .omega.-(subst.)-aryloxyalkyl halides or methanesulphonates, 1,2-epoxy-3-(subst.)-aryloxypropanes or with pyridoxal, converted into the compounds of general formula V, wherein R.sup.1 signifies a hydrogen atom and R.sup.2 possesses one of the given meanings or in which R.sup.1 and R.sup.2 together represent a pyridoxylidene radical.

As follows from the fact that the ammonolysis of isosorbide 2,5-diacylate preponderantly leads to the 5-aminoisoidide 2-acylate, the nucleophilic substitution of the 2-exo-acylate group in the isosorbide diacylate is sterically hindered. The degree of steric hindrance is temperature dependent. In order to obtain the 5-amino-2-acylate as quantitatively as possible from the corresponding diacylate, one works, therefore, preferably at a temperature of 80.degree. to 120.degree. C. since at temperatures above 120.degree. C. the 2-exo-group, even if only to a small extent, is also attacked by ammonia or by mono- or dialkylamine used instead of ammonia. As solubiliser, an alcohol, preferably ethanol, can be added to the aqueous ammonia solution or to the mono- or dialkylamine.

For the preparation of those compounds according to the invention of general formula V, wherein R.sup.1 and/or R.sup.2 signify a lower alkyl group with 1 to 4 C-atoms, the 1.4;3.6-dianhydro-D-gluctiol 2,5-diacylate is subjected to the aminolysis with primary or secondary alkylamines with 1 to 4 C-atoms, namely, advantageously under elevated pressure, preferably at a pressure of 2 to 20 ats., and elevated temperature, preferably at 90.degree. to 180.degree. C. The aminolysis is, completely analogously to the above-described ammonolysis, expediently carried out in a closed steel autoclave up to quantitative reaction. Subsequently, the hydrolysis is carried out in the previously described manner, followed by the esterification of the 2-hydroxy group with nitric acid.

The aminolysis can be carried out not only with methylamine, ethylamine, propylamine, butylamine, dimethylamine, diethylamine, dipropylamine, dibutylamine etc. but also, for example, with 1-aminoadamantane, as well as cyclic, non-aromatic secondary amines, such as pyrrolidine, piperidine, morpholine, 4-methylpiperazine and the like heterocyclic nitrogen bases and then leads to the compounds according to the invention of general formula V, wherein R.sup.1 and R.sup.2, together with the nitrogen atom to which they are attached, signify the residue of a cyclic, non-aromatic secondary amine possibly containing a further hetero atom.

For the preparation of those compounds of general formula V, wherein R.sup.1 signifies a lower alkyl group with 1 to 4 C-atoms and R.sup.2 an acyl radical, an .omega.-(subst.)-arylalkyl or -alkenyl radical, an .omega.-(subst.)-aryloxyalkyl radical or a 2-hydroxy-3-(subst.)-aryloxyprop-1-yl radical, the 5-lower alkylamino-5-desoxy-1.4;3.6-dianhydro-L-iditol 2-nitrates formed in the case of the aminolysis of isosorbide 2,5-diacylate with primary amines and subsequent alkaline hydrolysis and esterification with nitric acid are condensed completely analogously to the previously described manner, namely, with the corresponding acyl halides, .omega.-(subst.)-arylalkyl or -alkenyl halides or methanesulphonates, .omega.-(subst.)-aryloxyalkyl halides or methanesulphonates or with the 1,2-epoxy-3-(subst.)-arylpropanes.

In the case of a further route according to the invention for the preparation of the compounds according to the invention of general formula VI, one makes use of the surprisingly found fact that 1.4;3.6-dianhydro-D-glucitol 2,5-diacylates (dimesylate or ditosylate) are selectively attacked on the C.sup.5 -atom by sodium benzoate in a suitable solvent, preferably in a dipolar aprotic solvent, for example in anhydrous dimethylformamide, dimethyl sulphoxide or diethers of ethylene glycol, at temperatures of 100.degree. to 180.degree. C., preferably 120.degree. to 150.degree. C., so that, with reversal of configuration, 1.4;3.6-dianhydro-L-iditol 2-methanesulphonate 5-benzoate or 1.4;3.6-dianhydro-L-iditol 2-toluenesulphonate 5-benzoate result in high yield. This product is now again subjected to the ammonolysis with 25% ammonia solution or to aminolysis under elevated pressure and elevated temperature, whereby the benzoic acid ester is not split off with substitution but rather hydrolytically, namely, with maintenance of the configuration on the C.sup.5 -atom, whereas the acylate radical on the C.sup.2 -atom is substituted, with reversal of configuration, by the amino or alkylamino group to give the corresponding 5-amino-5-desoxy-1.4;3.6-dianhydro-D-glucitol or 5-alkylamino-5-desoxy-1.4;3.6-dianhydro-D-glucitol.

Since the last-mentioned elegant process involves a double selective reversal of configuration, the configuration of the end product is, with regard to its substituents, identical with the configuration of the starting compound; from the isosorbide disulphonate there again results an isosorbide derivative, namely, 5-amino- or 5-alkylamino-5-desoxy-1.4;3.6-dianhydro-D-glucitol, which then, as previously described, can be further worked up to give the desired compounds of general formula VI.

In order to convert the compounds according to the invention into their physiologically acceptable salts, there can be used inorganic acids and mineral acids, such as hydrohalic acids and phosphoric acids, as well as organic acids, such as carboxylic and sulphonic acids, for example malonic, succinic, lactic, tartaric, malic, benzoic, salicylic, citric, ascorbic, nicotinic or p-toluenesulphonic acid. The free bases can again be liberated from the acid-addition salts by treatment with strong bases, for example, sodium or potassium hydroxide.

Furthermore, the subject of the invention are pharmaceutical compositions which, besides the usual carrier and additive materials, contain at least one of the compounds according to the invention or of their physiologically acceptable salts. These compositions can be used as medicaments in human and veterinary medicine. Conventional carrier materials are, for example, water, vegetable oils, polyethylene glycols, glycerol esters, gelatine, carbohydrates, such as lactose or starch, magnesium stearate, talc or Vaseline. Conventional additive materials are, for example, preserving, stabilising, lubricating, wetting agents, emulsifiers, physiologically acceptable salts, buffer substances, colouring, flavouring and aroma materials. The selection of the carrier and additive materials depends upon whether the compounds according to the invention are to be administered enterally, parenterally or topically.

The compounds according to the invention can also be administered in admixture with other active materials, for example vitamins or known, commercially available heart-circulation agents, especially also with .beta.-receptor blockers.

5-Amino-5-desoxy-1.4;3.6-dianhydro-L-iditol 2-nitrate: (a) 1.4;3.6-Dianhydro-D-glucitol 2-methanesulphonate, 5-methanesulphonate and 2,5-dimethanesulphonate:

To a solution of 4.82 kg. (33 mol) 1.4;3.6-dianhydro-D-glucitol in 24 liters of pyridine, one adds dropwise, with the exclusion of moisture, stirring and cooling to -15.degree. to -20.degree., within the course of several hours, 3.1 liters (40 mol) methanesulphonic acid chloride. Subsequently, one further stirs for 15 hours, without cooling. One distils off the pyridine in vacuo, adds 15 liters of water to the oily residue, boils up and allows to cool. Suction filtration, washing with 4 liters of water and drying the crystalline precipitate gives 2.22 kg. (7.34 mol) 1.4;3.6-dianhydro-D-glucitol 2,5-dimethanesulphonate. The filtrate is neutralised, with stirring and water cooling, with about 1.5 kg. sodium hydroxide and evaporated to dryness in a vacuum at about 70.degree.. The dry residue is continuously hot extracted with a total of 30 liters of chloroform and the extract filtered hot. One allows the extract to stand for 15 hours at 20.degree., filters off the crystalline precipitate with suction, washes it twice with 2 liter amounts of chloroform, dries and obtains 2.3 kg. (10.26 mol) 1.4;3.6-dianhydro-D-glucitol 5-methanesulphonate. The combined filtrates are evaporated in a vacuum and the residue dissolved hot in 22 liters of ethanol. One leaves to stand for 15 hours at 20.degree., filters off the crystalline precipitate with suction, washes it twice with 3 liter amounts of ethanol, dries and obtains 0.65 kg. (2.90 mol) 1.4;3.6-dianhydro-D-glucitol 2-methanesulphonate. Evaporation of the filtrate gives 2.21 kg. (9.85 mol) of a mixture of the two isomeric monomethanesulphonates which, according to need, can be further separated by repetition of the alternating crystallisations from chloroform and ethanol or, by esterification with methanesulphonic acid chloride in pyridine, is completely converted into 1.4;3.6-dianhydro-D-glucitol, 2,5-dimethanesulphonate.

Analytical amounts of the methanesulphonates give, after recrystallisation, correct elementary analyses and the melting points and optical rotations stated in Table 1:

Thereafter, the reaction is quantitative. One evaporates under reduced pressure and dries azeotropically by the successive addition and renewed evaporation of 1 liter amounts of ethanol and chloroform. The oily residue is dissolved, with warming, in 500 ml. ethanol and diluted to 2 liters with isopropanol. Upon cooling, 311 g. (1.3 mol) 5-amino-5-desoxy-1.4;3.6-dianhydro-L-iditol crystallise out as methanesulphonic acid salt. A further 100 g.

A mixture of 302 g. (1 mol) 1.4;3.6-dianhydro-D-glucitol 2,5-dimethanesulphonate, 750 ml. 25% aqueous ammonia (10 mol) and 750 ml. ethanol is stirred in a closed steel autoclave for 4 days at 100.degree.. After cooling, one mixes with 1 liter of water and filters off with suction from unreacted dimethanesulphonate which has crystallised out (106 g.=0.35 mol). For the removal of ammonia, the filtrate is mixed with 104 g. (1.3 mol) sodium hydrogen carbonate and evaporated under reduced pressure. One dissolves in 5 liters of water and extracts elimination products therefrom with 500 ml. chloroform. The aqueous phase is continuously extracted with chloroform in a rotary perforator (Normag). 2,5-Diamino-2,5-didesoxy-1.4;3.6-dianhydro-D-glucitol formed as by-product remains in the aqueous phase.

The chloroform extract gives, after drying over anhydrous sodium sulphate, filtering and evaporating, 105 g. (about 0.55 mol) of a 1:4 mixture of 5-amino-5-desoxy-1.4;3.6-dianhydro-L-iditol and 5-amino-5-desoxy-1.4;3.6-dianhydro-L-iditol 2-methanesulphonate.

A mixture of 448 g. (2 mol) 1.4;3.6-dianhydro-D-glucitol 2-methanesulphonate (preparation see Example 1a) and 1500 ml. 25% aqueous ammonia is stirred for 1 day at 130.degree. in a closed steel autoclave. After cooling, one adds 30 g. active charcoal thereto, filters and extracts with 1 liter chloroform the 1.4;2.5;3.6-trianhydro-D-mannitol formed as by-product [after evaporation of the chloroform phase and recrystallisation from ether/petroleum ether, a total of 104 g.

In the case of the investigation of the pharmacological properties of the compounds according to the invention, as comparison compounds there was always used the commercially available compounds isosorbide dinitrate (ISDN) and isosorbide mononitrate (ISMN), whereby ISMN is 1.4;3.6-dianhydro-D-glucitol 2-nitrate.

The coronary flowthrough-increasing effectiveness of the compounds according to the invention was determined on isolated guinea pig hearts (isolated hearts according to Langendorff, method according to Bunger et al., Pfluger's Archiv, 353. 317-325 (1975)). After reaching the stationary state in the 30th minute, the hearts were each perfused with 50 ml. tyrode solution with a content of test substance of, in each case, 25 .mu.g./ml. Each test substance was tested on 3-6 hearts.

In each case, there was measured the inotropism, the flowthrough and the frequency, whereby the values given in Table I are average values of the percentage changes in comparison with the initial values. The comparison of the measured values shows that the coronary flowthrough-increasing effectiveness of the compounds according to the invention is greater than that of ISMN; the coronary flowthrough-increasing effectiveness of some substances even exceeds that of ISDN. Many of the substances according to the invention show favourable, inotropic- and frequency-lowering actions.

The spasmolytic effectiveness of the compounds according to the invention was determined on isolated rat aorta preparations with noradrenaline- and potassium chloride-induced contractions (method according to Wende and Peiper, Pfluger's Archiv, 320, 133-141 (1970); and Towart and Stoepel, Naunyn-Schmiedeberg's Archives of Pharmacology, suppl. Vol., 308, R 18 (1979)).

In Table II, there are given the concentrations of the test substances which are necessary for a 50% inhibition of the spasm (ED.sub.50 values). The spasmolytic effectivenesses of the compounds according to the invention are quite preponderantly better than those of ISMN and ISDN, especially when one takes into account the pharmacologically important ratio of the effective doses in the case of noradrenaline spasm and potassium chloride spasm.

The blood pressure-lowering effectiveness of the compounds according to the invention was measured in comparison with ISDN and ISMN on narcotised guinea pigs after i.v. administration. The values given in Table III (1/2) show that the compounds according to the invention are all more effective than ISMN, whereby compound No. 5 possesses a stronger action than ISDN.

The inotropic and heart-circulatory effectiveness of the compounds according to the invention was determined on mongrel cats of 1.5 to 3.5 kg. body weight with intravenous administration. The animals were narcotised with a mixture of chloralose-urethane (1.2 g./kg. urethane+40 mg./kg. chloralose administration i.p.). They breathed spontaneously through a tracheal canula. The A. carotis sinistra was used in order to place a catheter tip manometer into the left heart chamber. The V. jugularis served for injection purposes. A catheter was pushed via the A. femoralis dextra into the Aorta descendans and connected to a pressure recorded (Statham P 23Db). The heart frequency was recorded with a pulse frequency measurer (film Hugo Sachs Elektronik) from the left ventricular pressure signal.

As follows from the values given in Table IV (1-6), the effectiveness of the tested compounds according to the invention is better than that of the comparison compound ISDN. In particular, all compounds show, besides the strong blood pressure lowering, favourable frequency-lowering effects and, in some cases, long-lasting lowering of inotropism.

Furthermore, these actions were determined on mongrel cats of 2.5 to 3.5 kg. body weight in the case of intraduodenal administration. The animals were narcotised with a mixture of chloralose-urethane (1.2 g/kg. urethane+40 mg./kg. chloralose administered i.p.). They breathed spontaneously through a tracheal canula. The A. carotis sinistra was used in order to place a catheter tip manometer into the left heart chamber. The V. jugularis served for injection purposes. A catheter was pushed via the A. femoralis dextra into the Aorta descendans and attached to a pressure recorder (Statham P 23 Db). The heart frequency was recorded with a pulse frequency measurer (firm Hugo Sachs Elektronik) from the left ventricular pressure signal. A duodenal loop was exposed by a laparotomy. The substances to be tested were injected directly into the lumen.

As follows from the values given in Table V, the blood pressure-lowering action of the tested compounds according to the invention is better than those of the comparison compound ISDN.
