The polycyclic aminopyridine compounds respond to the formula (See Formula) wherein the different radicals have the meanings indicated in the specification. The process for the preparation of these compounds is characterized in that ketones of the general formula (II) are reacted with aminonitriles of the general formula (III) and, if necessary, the compounds of the formula (I) are alkylated, aralkylated or acylated or either the corresponding ketonic precursor is reduced. The compounds of the general formula (I) are especially suitable for the preparation of medicaments against memory disorders, such as senile dementia or Alzheimers disease.

Description

NEW POLYPHYNINIC AMINOPYRIDINE COMPOUNDS INHIBITORS OF ACETILCOLINESTERASE, PROCEDURE FOR PREPARING AND USING IT Field of the art The present invention relates to new compounds to polycyclic inopyridines, and to their pharmaceutically acceptable salts, inhibitors of the enzyme acetylcholinesterase, with therapeutic utility in the treatment of memory dysfunctions, such as senile dementia or aging of Alzheimer's, in which the drugs are indicated capable of increasing the level of the neurotransmitter acetylcholine in the central nervous system. Prior art Hershenson et al., J. Med. Chem. 29, 1125-1130 (1986), have reported that the level of acetylcholine is decreased in the brain of patients with Alzheimer's disease and have studied the usefulness of physostigmine, which is an inhibitor of the enzyme acetylcholinesterase, in the treatment of such patients. W. K. Summers et al., Clin. Toxicol., 1 £, 269 (1980), have described that the known acetylcholinesterase inhibitor called tacrine, 9-amino-l, 2,3,4-tetrahydro-acridine, of formula administered intravenously in combination with lecithin is useful in the treatment of Alzheimer's disease, although it has the disadvantage of its high toxicity. Subsequently, GM Shuts e et al., J. Med. Chem. 32. 1805-1813 (1989), have described 9-amino-1, -2, 3, 4-tetrahydroacridin-1-ol derivatives that also exhibit activity inhibitor of acetylcholinesterase and the patents or patent applications published US-A-4546104, EP-A-0268871, US-A- RRp. I? Q c to -4735953, US-A-4753950, US-A-4762841, EP-A-394950 and JP-A-03002166 describe other compounds related to the aforementioned chemical structures that also exhibit acetylcholinesterase inhibitory activity. For their part, the authors of the present invention have described in the patent application WO 93/13100 a process for the preparation of bis-pyridine derivatives with acetylcholinesterase inhibitory activity. Another known inhibitor of the mentioned enzyme is the product called Huperzine A, of formula In any case, there remains a need for new alternative compounds, more effective as acetyl-cholinesterase inhibitors, which allow an increasingly effective and safe treatment of diseases as serious and as costly as Alzheimer's disease. The inventors of the present invention have discovered a group of novel polycyclic aminopyridines, some of which compounds are much more effective than tacrine in their acetylcholinesterase inhibitory action. OBJECT OF THE INVENTION The object of the present invention are new polycyclic aminopyridine compounds and their pharmaceutically acceptable salts, with a high inhibitory efficiency of the acetylcholinesterase enzyme. Another object of the present invention is the use of the novel polycyclic aminopyridine compounds, and their pharmaceutically acceptable salts, in the preparation of medicaments against memory disorders such as senile dementia or Alzheimer's disease, as well as pharmaceutical compositions which they contain them. Still another object of the present invention is a process for obtaining said new compounds. DESCRIPTION OF THE INVENTION The novel aminopyridine compounds object of the present invention correspond to the general formula (I) wherein R can be hydrogen, alkyl, aralkyl or acyl.

Examples of such aralkyl groups include benzyl, phenethyl, 3-phenylpropyl, 4-phenylbutyl, 2- (4-methoxyphenyl) ethyl, 2- (2-methylphenyl) ethyl, 2- (4-fluorophenyl) ethyl and 4- (4-chlorophenyl) butyl. The term "acyl" means an alkylcarbonyl or aralkylcarbonyl group wherein the alkyl and aralkyl residues may adopt the values defined above. In the context of RL and R ,, the terms alkyl and aralkyl have the meaning given above for R. The alkoxy substituent and the alkoxy group of the alkoxycarbonyl substituent may take the meanings given above for the lower alkoxy group.

The R groups, substituents of the ring fused to X or Y, can be hydrogen, lower alkyl or lower alkoxy of one to four carbon atoms, or halogen (fluorine, chlorine, bromine and iodine). Since the compounds of general formula (I) have at least two chiral centers, that is to say two asymmetric carbons capable of generating optical isomerism, the present invention relates both to the racemic compounds and to all possible enantiomers thereof or to their mixtures in different proportions. The pharmaceutically acceptable addition salts may be of organic or inorganic acids such as hydrochloric, hydrobromic, sulfuric and nitric acids between the inorganic and tartaric, succinic, maleic, fu aric and citric acids among the organic. The compounds of the general formula (I) object of the present invention, in which R is hydrogen, can be prepared, in general, by reaction of the ketones of the general formula (II) / R1 (CH2> m- / C / \ XY (ID ~ ((CH2) n with the aminonitriles of general formula (III) in whose general formulas (II) and (III) A, Rt, R ,, X, Y, m and n have the meanings defined above, in the presence of a Lewis acid as catalyst, or of a dehydrating agent, in a suitable solvent. Said reaction leads directly to the compounds of general formula (I) in which R is hydrogen, which can be purified by conventional methods such as, for example, column chromatography, selective dissolution with different solvents or crystallization, either in the form of of free bases or their addition salts of organic or inorganic acids. In ketones of general formula (II) it is necessary that at least one of the two be equal to or greater than one, that is to say, it is essential that there is at least one methylene group in alpha position with respect to the biological function. tonic. The Lewis acid used as catalyst in the condensation of the ketones (II) with the aminonitriles (III) can be, among others, aluminum trichloride, zinc dichloride, titanium tetrachloride, etc., all of them in anhydrous form. As the reaction solvent, aprotic solvents are used, for example nitrobenzene, 1,2-dichloroethane, dichloromethane and dimethylformamide, among others. The reaction is carried out at temperatures between 0 and 150 SC, with reaction times ranging from 1 to 48 hours, depending on the type of catalyst and the solvents used. The compounds of the general formula (I) in which R is different from hydrogen can be obtained by alkylation, aralkylation or acylation of the compounds of general structure (I) in which R is hydrogen, according to methods known to the person skilled in the art, for example, those described in US-A-4753950 and in published patent application JP-A-03002166. Some compounds (I), in which X or Y is an alkylene group substituted with a hydroxyl group, in the endo position, for example X-CH2-CH (endo-OH) -CH2-, can be obtained more conveniently from of the corresponding precursor compounds in which X or Y is an alkylene group substituted with an oxo group in the appropriate position, for example X = CH2-C0-CH2-, by reduction with suitable reducing agents such as complex metal hydrides, by Examples are boron sodium hydride or lithium aluminum hydride, hydrogenation in the presence of a catalyst, metals in a protic medium, for example sodium in ethanol, etc. All possible epantiomers of the compounds of general formula (I) can be obtained by conventional techniques well known to the person skilled in the art, for example by selective or fractional crystallization of their diastereoisomeric salts with optically active organic acids, by chromatographic methods, by enantioselective synthesis , etc. The formation reactions of the pharmaceutically acceptable salts of the compounds of general formula (I) are carried out by conventional methods, by reacting the basic organic compound with an organic or inorganic acid in an appropriate solvent, such as water, alcohols, for example, methanol, ethanol, isopropanol, etc., or ethers such as diethyl ether, tetrahydrofuran, dioxane, etc. Preferred, for the purpose of the present invention, are compounds which, within the framework of general formula (I), correspond to the general formula in which A, X and Y have the meanings already enunciated for the general formula (I). Said compounds can be obtained by reacting the ketones which, within the framework of the general formula (II), correspond to the general formula wherein X and Y have the meanings already mentioned, with the aminonitriles of the general formula (III), in the manner already explained for the preparation of the compounds of the general formula (I). Among the starting ketones (II) to obtain the compounds according to the invention, those represented in Table 1 can be mentioned as particular cases. ? abla 1. Examples of ketones given: i) Some of the ketones (II) used as starting materials in the preparation of the compounds (I) are previously described compounds and, therefore, can be prepared according to said earlier descriptions. Thus, Ha has been described by J. G. Henkel et al. J. Org. Chem. 48, 3858-3859 (1983); Hb by K. Kimoro et al., Bull. chem. Soc. Jpn. 45., 3698-3702 (1972); Ilf by H. Quast et al., Liebst Ann., 725-738 (1995); Hg for t. Momose et al., 'Chem, Pharm. Bull. 2 £, 238-295 (1978), llh by RS Henry et al., "J. Chem. = Oc, Perkin Trans. 2, 1549-1553 (1976), and n0 by R. Bishop, Aust. J. Chem 21, 319-325 (1984). The ketones, lid, lid, lie, Ili, pj and IIk as well as other ketones related thereto, can be prepared by a procedure consisting of the sequence of reactions of the following scheme: The diketones (VI), in which X has the aforementioned meaning, are reacted with organometallic reagents (organomagnesium or organolithic) to give rise to the oxaadamantanols (V) which, by reaction with methanesulfonyl chloride, give rise to the corresponding methanesulphonates (IV). These, by treatment with silica gel, are transformed into the corresponding ketones (II). Ketones III and Hm, as well as other ketones related thereto, can be obtained, according to the sequence of reactions of the following scheme: That is, by hydrolysis of the acetal esters (VII), whose preparation can be carried out according to the method described by AP Koziko ski et al., Heterocycles 39, 101-116 (1994), and the decarboxylation of the corresponding ketoacids (HIV). ). The ketone Hn has been prepared from ketone acetal IX, described by P. Camps et al., Tetrahedron Lett. 25., 3187-3190 (1994), by reaction with methyl-lithium followed by dehydration and hydrolysis of the alcohol X formed, according to the following scheme: Similarly, ketones related to Hn can be prepared. In general, the starting ketones (II) can be prepared by one of the described methods introducing, depending on the substituents desired, variations obvious to the skilled person. Among the starting aminonitriles (III) to obtain the compounds according to the invention, those represented in Table 2 can be mentioned as particular cases.
Table 2. Examples of starting aminonitriles (III) The aminonitriles HIv,? Nw and r? Lx can be purchased commercially. The remaining aminonitriles can be obtained according to the procedures described by F. Hunziker et al., Eur. J. Med. Chem. 16_, 391-398 (1981) and by H. E. Schroeder et al., J. Am. Chem. Soc. 71, 2205-2207 (1949). In general, the compounds of the general formula (III) are known and can be prepared by conventional means easily accessible to the expert. Among the compounds of general formula (i) obtained, those which are shown in Table 3 can be mentioned, in particular cases. Each compound is named with the Roman numeral I followed by two corresponding lowercase letters, first of all place with the one assigned in table 1 to the starting ketone from which it comes and, secondly, with the one assigned in table 2 to the aminonitrile from which it also comes.
Table 3.? JemDlc? of compounds of general formula (I) The formulas developed from the compounds of table 3 are the following: "The products Iqw, irw and rr2 are not obtained by direct reaction of a ketone (II) with an aminonitrile (III), but by reduction of direct ketonic precursors described by the authors of the present invention in the patent application WO 93 / 13100. However, for consistency the way of naming them has been maintained as if they came from hypothetical starting ketones Hq and Hr. The rest of the products of general formula (I) can be obtained by reaction of the ketones (II) with the aminonitriles (III) in the manner already explained The compounds of general formula (I) in enantiomerically pure form can be obtained by various methods: for example, by medium pressure column chromatography using microcrystalline cellulose triacetate 15 - 25 μm (Merck) as the chiral stationary phase, as described in examples 37 and 38. Alternatively, some of the compounds of general formula (I) in enantiomerically pure form can They can be obtained through enantioselective syntheses, in a manner analogous to the preparation of the corresponding radicle compounds, by reaction of the ketones which, within general formula (II), correspond to the general formula - enriched in one or the other of the enantiomers, with the arai-nitriles of general formula (III), in the manner already explained for obtaining the compounds of general formula (I) in racemic form. The ketone (He) (which corresponds to the above formula with X = CH, Rβ = CH, CH 3), as well as other ketones related thereto, can be obtained in enriched form in one or the other of the enantiomers through the Reaction sequence of the following scheme: (XI) (XII) (X? D (II) Achiral compound (XII). (Xpi) and (ID) Chiral compounds enriched in one of the enantisomers.
The compounds (XI) in which X can adopt any of the values indicated above (for example, X = CH3, ortho-phenylene, etc.), can be obtained by acetaliZation of the corresponding compounds (VI) with ethylene glycol or other suitable reagents, according to procedures described [T. Mounted and o. Muroaka, Chem. Pharm. Bull. =., 288-295 (1978)] and are the starting products of this synthetic enantioselective sequence. The reaction of the achiral achiral ketones (XI) with a lithium amide derived from a chiral amine in an enantiomerically pure form, for example (+) - bis [(R) -l-phenylethyl amine, as described for related cases [NS Simpkins et al., Tetrahedron 49, 207-218 (1993) and references cited therein] leads to highly enolate anions in one of the enantiomers, by enantioselective abstraction of a proton from one or the other of the positions -carbonyls, which by reaction with N-phenylbis (trifluoromethanesulfonyl) imide [JE McMurry and WJ Scott, Tetrahedron Lett.2,979-982 (1983)] or with trifluoromethanesulfonic anhydride [PJ Stang and W. Treptow, Synthesis, 283-284 (1980)] give the corresponding enol trifluoro-romethanesulfonates (XII) enriched in one or the other enantiomer, depending on the configuration of the starting amine. These enol trifluoromethanesulfonates (XII) by reaction with Grignard reagents in the presence of complexes of Cu (I) c They arise from acetals (XIII) in which R represents an alkyl or aralkyl group, with the meaning given above in the context of R, or phenyl or substituted phenyl as defined above in the context of R ". The enantiomeric excess of the acetals (XIII) is apparently the same as that of their precursors (XII), that is to say that this reaction proceeds with minimal or no epimerization [for a related reaction, see: J. Kant, J. Org. . Chem. 58. 2296-2301 (1993)]. The hydrolysis of these acetals leads to the corresponding ketones (II), a process which, under the reaction conditions described in Examples 33 and 34, also proceeds with minimal or no epimerization, so that the enantiomeric excess of the ketones (II ) is similar to that of the precursor acetals (XIII). The reaction of these ketones (II) enriched in one or other of the enantiomers with the aminonitriles (III) under the conditions described above starting from the racemic (II) ketones, leads to the aminoquinolines (I) enriched in one or the other enantiomer depending on the ketone (II) used, although the enantiomeric excess of the aminoquinoline (I) obtained is usually lower than that of the ketone (II) starting due to to the epimerization of this last before the condensation. By fractional crystallization of these aminoquinolines or their salts, for example the corresponding hydrochlorides, the enantiomerically pure or highly enriched aminoquinolines (I) in one or the other of the enantiomers can be obtained. The compounds of general formula (I), object of the present invention, have a marked inhibiting activity of the acetylcholinesterase enzyme, some of them being considerably more active than tacrine, known inhi-bidor of said enzyme which is already used as a therapeutic agent in cases of senile dementia or Alzheimer's disease. The compounds object of the invention, as well as their pharmaceutically acceptable acid addition salts, can be administered orally or parenterally in the form of conventional pharmaceutical preparations, such as tablets, capsules, syrups and suspensions. Alternatively, they can be administered parenterally in the form of solutions or emulsions, etc. They can be applied directly to the rectum, in the form of suppositories. The preparations may contain physiologically acceptable carriers, excipients, activators, chelating agents, stabilizers, etc. In the case of injectables, physiologically acceptable buffers, solubilizing or isotonic agents can be incorporated. The daily dose may vary depending on the symptoms of the disease, age, body weight of patients, administration mode, etc. , and the normal dose of an adult person can be between 1 and 500 mg divided into several doses per day. Below is a series of examples that should be interpreted as illustrative of the object of the present invention and not as limiting the scope thereof. Examples The melting points of the compounds have been determined in a Gallenkamp apparatus, model MFB.595.01QM. The IR spectra were recorded on a Perkin Elmer FT-IR spectrophotometer, model 1600. Thin-layer chromatography was performed on silica gel 60 F254 (Alugran R sil / UV254). Silica gel 60 (Merck, 230-440 mesh) was used for column chromatography. The microanalyses were carried out in the Microanalysis Service of the Research and Development Center, C.I.D., Barcelona, Spain, and they agree with the theoretical values with an error of ± 0.3% except if indicated otherwise. In general, the compounds were dried under vacuum (1 Torr) at 80BC for 2 days (standard conditions).
