TECHNICAL FIELD

The present invention relates to a 4a-aryldecahydroisoquinoline compound and a pharmacologically acceptable salt thereof, and also relates to a medicine, a cerebral cytoprotective agent, an analgesic, and an antitussive, each of which contains the foregoing compound or salt as an active ingredient.

BACKGROUND ART

Recently, cases of various cerebrovascular diseases have increased with the arrival of an aging society. Cerebrovascular diseases are considered to be caused by aging, hypertension, arterial sclerosis, hyper lipidemia, and the like, and are generally called as stroke. However, cerebral functional damage due to head trauma and the like are occasionally included in the cerebrovascular diseases in a broad sense.

Stroke is roughly divided into infarctional diseases and hemorrhagic diseases such that the former includes cerebral infarction (cerebral thrombosis and cerebral embolus) and the latter includes cerebral hemorrhage and subarachnoid hemorrhage. These diseases cause supply shortages of glucose, oxygen, and the like, which are the energy source of cerebral neurocytes; thus cerebral edema or infarction consequently occurs, resulting in death of the cerebral neurocytes positioned in and around the ischemic areas. As a result, various aftereffects such as cerebrovascular dementia occur, and together with Alzheimer-type senile dementia and the like, they appear as medically and socially serious problems at present.

Conventionally, medicines developed to be applied for improvement in psychoneurotic symptoms associated with the above cerebrovascular diseases and senile dementia mainly take effect through promoting supply of glucose, oxygen, etc. to ischemic areas by increasing the blood flow to the brain, and based on these functional mechanisms, they are called by ambiguous names such as agents for improving cerebral circulation, activators for cerebral metabolism, and agents for improving cerebral functions. However, almost all of these medicines are aimed at improving the above aftereffects and are regarded to be effective for improving peripheral symptoms such as volition disorder, emotional disorder, and abnormal behavior; meanwhile their effectiveness on core symptoms of dementia such as memory disorder(s) is considered to be doubtful by many people. Anyway, these medicines are almost ineffective for cerebral neurocytes damaged by cerebrovascular disorder and, up to the present, almost no medicine has been found which is effective for this damage. In particular, treatment of the acute stage which is within 24 hours from the onset of cerebrovascular diseases is regarded to be important, and development of a cerebral cytoprotective agent which has reliable protective effects and which can be used in a safe and easy way is in demand under present conditions.

Meanwhile, analgesics which exhibit their effect by affecting the central nervous system and which are represented by morphines and the like are frequently used at present because of their strong analgesic action, however strict management is required in using these medicines since they have severe adverse effect including dependence, respiratory supression and smooth muscle deppressomotor (constipation). Therefore, central analgesics have been in demand which are highly effective and which can be used with relief. In addition, codeine and dextromethorphan which are known as strong central antitussives are generally used for not only prescription medicines but also a component of commercially available cold medicines, and these medicines fundamentally have similar severe adverse effect. In particular, abuse of antitussives containing codeine and psychogenesis of dextromethorphan are serious, and development of safer and stronger central antitussives has been expected.

trans-2-allyl-8a-methoxy-4a-(3-acetoxyphenyl)-6.beta.-[N-methyl-(benzyloxy carboxamido)]decahydroisoquinoline, but the present invention is not limited to these compounds. The compounds incorporated in the present invention includes (+), (-), and (+) isomers of these.

In practice, compounds of general formula (I) incorporated in the present invention can be obtained by the following methods:

Among the compounds of general formula (I) incorporated in the present invention, those in which A is --XC(.dbd.Y)--, --XC(.dbd.Y)Z--, or XSO.sub.2 -- (wherein X is NR.sup.4 or O, Y is O or S, Z is O or NH, and R.sup.4 is as defined above) can be practically obtained by the following method: ##STR4##

In general, such compounds can be obtained by condensation of a 6-amino body or a 6-hydroxy body, both of which have a general formula (II) (wherein R.sup.1, R.sup.2 and R.sup.3 are as defined above; and E is NHR.sup.4 (R.sup.4 is as defined above) or OH), with a carboxylic acid derivative having a general formula (IIIa) (wherein B and R.sup.5 are as defined above), a formic acid derivative having a general formula (IIIb) (wherein Z, B and R.sup.5 are as defined above), an isocyanic acid or an isothiocyanic acid derivative having a general formula (IIIc) (wherein B and R.sup.5 are as defined above), or with a sulfonic acid derivative having a general formula (IIId) (wherein B and R.sup.5 are as defined above), as is shown in Chart 1.

In practice, the 6-amino body used for the above condensation can be obtained by the following step: ##STR5##

As is shown in Chart 2, the 6-amino body having a general formula (IIn) (wherein R.sup.1, R.sup.2 and R.sup.3 are as defined above; and R.sup.4 is as defined above, except for exclusion of hydrogen) can be obtained by mixing a 6-keto body having a general formula (IV) (wherein R.sup.1, R.sup.2 and R.sup.3 are as defined above) and a primary amine having a general formula (V) (wherein R.sup.4 is as defined above, except for exclusion of hydrogen) in a solvent, followed by hydrogenation in the presence of an appropriate amount of an acid and a metal catalyst or reduction using a metal hydride reductant in the presence of an acid.

Among the 6-amino bodies having the general formula (IIn) shown in Chart 2, a trans-6.alpha.-amino body having a general formula (IIt .alpha.) (wherein R.sup.1, R.sup.2 and R.sup.3 are as defined above; and R.sup.4 is as defined above, except for exclusion of hydrogen), in which the ring juncture positions of the decahydroisoquinoline skeleton are fused in a trans form and stereochemistry of the 6-position is .alpha., or a trans-6.beta.-amino body of general formula (IIt .beta.) (wherein R.sup.1, R.sup.2 and R.sup.3 are as defined above; and R.sup.4 is as defined above, except for exclusion of hydrogen), in which the the ring juncture positions of the decahydroisoquinoline skeleton are fused in a trans form and stereochemistry of the 6-position is .beta. can be similarly obtained by using a trans-6-keto body [disclosed in Japanese Unexamined Patent Publication Nos. 4-275288, 4-297458, 5-155857, and the like] having a general formula (IVt) (wherein R.sup.1, R.sup.2 and R.sup.3 are as defined above) in which the ring juncture positions of the decahydroisoquinoline skeleton are fused in a trans form, and a primary amine having the general formula (V), as is shown in Chart 3. ##STR6##

Among the above methods, hydrogenation or reduction by sodium triacetoxyborohydride is preferred for highly selectively obtaining a trans-6.alpha.-amino body having the general formula (IIt .alpha.). However, reduction by other metal hydride reductants is advantageous in that the a body having the general formula (IIt .alpha.) and the .beta. body having the general formula (IIt .beta.) can be occasionally obtained at the same time and the desired stereoisomer compound can be obtained using general isolation and purification methods, although the ratio of the resulting isomers varies according to the substrate. This method is also useful when a substrate used for obtaining an amino body has a functional group, such as olefin, that is reactive under hydrogenation conditions.

In the case of reduction by hydrogenation, the amine is used in an amount of 1 to 30 equivalents, preferably 1 to 10 equivalents. Any solvent, for example, an alcohol such as methanol or ethanol, an ether such as THF, ether, DME, or dioxane, or an aromatic hydrocarbon such as benzene or toluene can be used as the reaction solvent, as long as it is inactive under hydrogenation conditions; and among these, an alcohol is preferable and methanol is particularly preferable. Any acid, for example, an inorganic acid such as hydrochloric acid, hydrobromic acid, sulfuric acid, or phosphoric acid, a sulfonic acid such as methanesulfonic acid, benzenesulfonic acid, or p-toluenesulfonic acid, or an organic carboxylic acid such as benzoic acid, acetic acid, or oxalic acid, can be used as the coexisting acid, so far as it generally forms a salt with an amine; and among these, hydrochloric acid, sulfuric acid, acetic acid, and methanesulfonic acid are preferable and, in general, satisfactory results can be obtained by using hydrochloric acid in an amount of 1 equivalent less than the total amount of a base. These acids may be added to the reaction system by making a salt with the substrate or the reagent beforehand. In some cases, the reaction can be conducted without using any of these acids. Although, any catalyst which is used for general hydrogenation, for example, a platinum catalyst such as platinum oxide or platinum hydroxide, a palladium catalyst such as palladium hydroxide or palladium-carbon, or a nickel catalyst such as Raney nickel, can be employed as the metal catalyst, a platinum catalyst, in particular platinum oxide, is preferable. The reaction temperature is -30.degree. C. to 80.degree. C. and preferably -10.degree. C. to 50.degree. C.; the hydrogen pressure is 1 to 100 atm and preferably 1 to 30 atm; and in general, satisfactory results can be obtained at room temperature and atmospheric pressure.

When reduction is conducted using a metal hydride, the amine is used in an amount of 1 to 30 equivalents and, preferably, 1 to 15 equivalents. As the solvent, an alcohol such as methanol or ethanol, an ether such as THF, ether, DME, or dioxane, an aromatic hydrocarbon such as benzene or toluene, or halogen such as dichloromethane or 1,2-dichloroethane can be used; and among these, an alcohol is preferable and methanol is particularly preferable. THF, dichloroethane, and the like are preferably used when using a certain kind of reductants. Any acid, for example, an inorganic acid such as hydrochloric acid, hydrobromic acid, sulfuric acid, or phosphoric acid, a sulfonic acid such as methanesulfonic acid, or p-toluenesulfonic acid, or an organic acid such as benzoic acid, acetic acid, or oxalic acid, can be used, so far as it generally forms a salt with an amine; and among these, hydrochloric acid, sulfuric acid, acetic acid, and methanesulfonic acid are preferable. Furthermore, these acids may be added to the reaction system by making a salt with the substrate or reagent beforehand. In some cases, the reaction can be conducted without using any of these acids. The reaction can be carried out using a metal hydride reductant relatively stable even when being with an acid, and examples of the reductant are sodium borohydride, sodium cyanoborohydride, zinc borohydride, sodium triacetoxyborohydride, tetramethylammonium triacetoxyborohydride, and borane-pyridine. In particular, sodium cyanoborohydride in methanol and sodium triacetoxyborohydride in THF or dichloroethane are preferable. Although the reaction temperature is -30.degree. C. to 100.degree. C. and preferably -10.degree. C. to 50.degree. C., satisfactory results can be generally obtained at room temperature.

Among trans-6.beta.-amino bodies of general formula (IIt .beta.), a trans-6.beta.-amino body of general formula (IIth .beta.) (wherein R.sup.1, R.sup.2 and R.sup.3 are as defined above) in which R.sup.4 is hydrogen can be obtained in a further stereoselective way from a trans-6-keto body having the general formula (IVt) (wherein R.sup.1, R.sup.2 and R.sup.3 are as defined above) by the steps shown in Chart 4. ##STR7##

In the first step, the ketone moiety of a trans-6-keto body of general formula (IVt) (wherein R.sup.1 and R.sup.2 are as defined above; and R.sup.3 is as defined above or trisubstituted silyl) is converted into a trans-6.alpha.-hydroxy body of general formula (VIt) (wherein R.sup.1, R.sup.2 and R.sup.3 are as defined above) by reduction using a metal hydride reductant or reduction by hydrogenation under the presence of an acid and a metal catalyst. Although sodium borohydride, sodium cyanoborohydride, zinc borohydride, sodium triacetoxyborohydride, L-Selectride, and lithium aluminum hydride can be used as the metal hydride reductant, satisfactory results can be obtained by sodium borohydride. As the solvent, an alcohol such as methanol or ethanol, or an ether such as THF, ether, DME, or dioxane can be used; and an alcohol, in particular methanol, is preferable. In the case of hydrogenation, as the solvent, an alcohol such as methanol or ethanol, or an ether such as THF, ether, or dioxane is preferable; and an alcohol, in particular methanol, is preferable. As the coexisting acid, an inorganic acid such as hydrochloric acid, hydrobromic acid, sulfuric acid, or phosphoric acid, a sulfonic acid such as methanesulfonic acid or p-toluenesulfonic acid, or an organic acid such as benzoic acid, acetic acid, or oxalic acid, can be used; and hydrochloric acid and acetic acid are particularly preferable. Although, any metal catalyst used for general hydrogenation, for example, a platinum catalyst such as platinum oxide or platinum hydroxide, a palladium catalyst such as palladium hydroxide or palladium-carbon, or a nickel catalyst such as Raney nickel, can be used as the metal catalyst, a platinum catalyst, in particular platinum oxide, is preferable. The reaction temperature is -30.degree. C. to 80.degree. C. and preferably -10.degree. C. to 50.degree. C.; the hydrogen pressure is 1 to 100 atm and preferably 1 to 30 atm; and in general, satisfactory results can be obtained at room temperature and atmospheric pressure.

In the second step, the trans-6.alpha.-hydroxy body of general formula (VIt) is converted into a trans-6.beta.-azide body of general formula (VIIt) (wherein R.sup.1, R.sup.2 and R.sup.3 are as defined above) by substituting the hydroxy group of the trans-6.alpha.-hydroxy body by an azide group with inversion of stereochemistry. According to a method of direct reaction of the trans-6.alpha.-hydroxy body, a hydrogen azide is employed and a combination of an azodicarboxylate and triphenylphosphine is used as an activator [O. Mitsunobu, Synthesis, 1 (1981)]. In this case, a hydrocarbon such as benzene or toluene is preferably used as the reaction solvent, and a diethyl azodicarboxylate or a diisopropyl azodicarboxylate is preferably used as an azodicarboxylate. Moreover, the substitution can be conducted more readily by converting the hydroxy group to a leaving group such as a sulfonate ester, etc. according to a conventional method before reacting with a metal azide. Preferred leaving groups are methanesulfonate, benzenesulfonate, and p-toluenesulfonate in this case. In general, highly polar solvents are preferable, and DMF, DMSO, HMPA, acetone, water, and mixtures thereof are particularly preferable. Lithium azide and sodium azide are most preferable as the metal azide. In some cases, a reaction additive such as ammonium chloride or trimethylsilyl chloride is preferably added. Although the reaction temperature is 0.degree. C. to 200.degree. C. and preferably 40.degree. C. to 150.degree. C., the reaction can be conducted at a reflux temperature in a simple way.

In the third step, the azide moiety of the trans-6.beta.-azide body of general formula (VIIt) (wherein R.sup.1, R.sup.2 and R.sup.3 are as defined above) is converted into a trans-6.beta.-amino body of general formula (IIth.beta.) (wherein R.sup.1, R.sup.2 and R.sup.3 are as defined above) by reduction using a metal hydride reductant or reduction by hydrogenation in the presence of an acid and a metal catalyst. Although sodium borohydride, sodium cyanoborohydride, zinc borohydride, sodium triacetoxyborohydride, L-Selectride, and lithium aluminum hydride can be used as the metal hydride reductant, satisfactory results can be obtained using sodium borohydride. An alcohol such as methanol or ethanol, or an ether such as THF, ether, DME, or dioxane can be used as the solvent; and an alcohol, in particular methanol, is preferable. In the case of hydrogenation, an alcohol such as methanol or ethanol, or an ether such as THF, ether, or dioxane is preferably used as the reaction solvent; and an alcohol, in particular methanol, is preferable. The coexisting acid includes inorganic acids such as hydrochloric acid, hydrobromic acid, sulfuric acid, and phosphoric acid, sulfonic acids such as methanesulfonic acid and p-toluenesulfonic acid, and organic acids such as benzoic acid, acetic acid, and oxalic acid; and hydrochloric acid and acetic acid are preferable among these. Although, any metal catalyst used for general hydrogenation, for example, a platinum catalyst such as platinum oxide or platinum hydroxide, a palladium catalyst such as palladium hydroxide or palladium-carbon, or a nickel catalyst such as Raney nickel, can be used as the metal catalyst, a platinum catalyst, in particular platinum oxide, is preferable. The reaction temperature is -30.degree. C. to 80.degree. C. and preferably -10.degree. C. to 50.degree. C.; the hydrogen pressure is 1 to 100 atm and preferably 1 to 30 atm; and in general, satisfactory results can be obtained at room temperature and atmospheric pressure.

When a trans-6-keto body is used, that is included in the trans-6-keto bodies having the general formula (IVt) and that has a general formula (IVtp) (wherein R.sup.1, R.sup.2 and R.sup.3 are as defined above) in which R.sup.3 is hydrogen, as is shown in Chart 5, it is occasionally preferable to convert the trans-6-keto body into another trans-6-keto body having a general formula (IVtg) (wherein R.sup.1 and R.sup.2 are as defined above; and G is trisubstituted silyl group) in which G is introduced to protect the active hydrogen in the phenolic hydroxy group before subjecting the trans-6-keto body to the steps shown in Chart 4.

G can be introduced by a reaction with silyl chloride in the presence of a base. Trimethylsilyl chloride, triphenylsilyl chloride, t-butyldimethylsilyl chloride, and diphenylmethylsilyl chloride can be used as the silyl chloride, and t-butyldimethylsilyl chloride is preferable. The base used for the reaction includes tertiary amines such as triethylamine, diisopropylethylamine, and Proton Sponge, pyridine, dimethylaminopyridine, and imidazole; and among these, imidazole is preferable. Although the reaction solvent includes halocarbons such as dichloromethane, chloroform, carbon tetrachloride, and 1,2-dichloroethane, ethers such as ether, THF, DME, and dioxane, and pyridine; DMF and dichloromethane are preferable. The reaction can be conducted at a temperature ranging from -80.degree. C. to 100.degree. C. and, in particular, satisfactory results can be obtained from 0.degree. C. to the vicinity of room temperature. ##STR8##

The following reduction process of the trans-6-keto body having the general formula (IVtg) (wherein R.sup.1 and R.sup.2 are as defined above; and G is a trisubstituted silyl group) to a trans-6.beta.-hydroxy body having a general formula (VItg) (wherein R.sup.1 and R.sup.2 are as defined above; and G is a trisubstituted silyl group) and the introduction process of an azide group into a trans-6.beta.-azide body having a general formula (VIItg) (wherein R.sup.1 and R.sup.2 are as defined above; and G is trisubstituted silyl group) can be carried out according to the first and second steps shown in Chart 4, respectively.

The step for converting a trans-6.beta.-azide body having the general formula (VIItg) (wherein R.sup.1 and R.sup.2 are as defined above; and G is a trisubstituted silyl group) into another trans-6.beta.-azide body having a general formula (VIItp) (wherein R.sup.1 and R.sup.2 are as defined above) by removing the protective trisubstituted silyl group G can be conducted according to a conventional method. In general, an acid such as hydrochloric acid, sulfuric acid, acetic acid, or hydrofluoric acid; a quaternary ammonium salt such as tetrabutylammonium fluoride, tetrabutylammonium chloride, and pyridinium hydrofluoride; or a base such as sodium hydroxide, potassium hydroxide, and potassium carbonate are used for the conversion. However, in general, the conversion can be sufficiently conducted by using 1 to 20 equivalents, in particular 1 to 5 equivalents, of hydrochloric acid or tetrabutylammonium fluoride. Ethers such as THF, ether, DME, and dioxane, halocarbons such as dichloromethane and chloroform, acetonitrile, and the like are used as the reaction solvent; and THF is preferable among these. The reaction can be conducted at a temperature ranging from -20.degree. C. to 100.degree. C. and, in general, satisfactory results can be obtained at room temperature.

The above step is followed by a conversion step of the trans-6.beta.-azide body having a general formula (VIItp) (wherein R.sup.1 and R.sup.2 are as defined above) to a trans-6.beta.-amino body having a general formula (IIthp .beta.) (wherein R.sup.1 and R.sup.2 are as defined above) by reducing the azide moiety of the trans-6.beta.-azide body. This step can be conducted according to the third step shown in Chart 4.

Condensation with a carboxylic acid derivative (IIIa) can be conducted by subjecting the 6-amino body (IIn) to a reaction with the corresponding acid chloride or acid anhydride in the presence of a base or a reaction with a carboxylic acid per se using N,N'-dichlorohexylcarbodiimide (hereinafter referred to as DCC), 1,1'-carbonyldiimidazole, bis-(2-oxo-3-oxazolidinyl)phosphinic chloride (hereinafter referred to as BOPCl), or the like. The acid chloride and acid anhydride are each used in an amount of 1 to 20 equivalents and, preferably, 1 to 5 equivalents. The solvent used for the above reaction includes halocarbons such as dichloromethane, chloroform, carbon tetrachloride, and 1,2-dichloroethane, ethers such as ether, THF, DME, and dioxane, pyridine, water, and mixtures thereof; and dichloromethane, chloroform, and a THF-water mixture are preferable when an acid chloride is used, and pyridine is preferably employed as both a base and a solvent when an acid anhydride is used. The base employed for the reaction includes tertiary amines such as triethylamine, diisopropylethylamine, and Proton Sponge, organic bases such as pyridine, dimethylaminopyridine, and imidazole, and inorganic bases such as potassium carbonate, sodium carbonate, sodium hydrogencarbonate, sodium hydroxide, and potassium hydroxide; and, in general, satisfactory results can be obtained by using 1 to 20 equivalents, preferably 1 to 5 equivalents, of triethylamine when the solvent is chloroform, and by using 1 to 20 equivalents, preferably 1 to 5 equivalents, of potassium carbonate, sodium carbonate, or sodium hydrogencarbonate when the solvent is a THF-water mixture. The reaction can be conducted at a temperature ranging from -80.degree. C. to 100.degree. C. and, in particular, satisfactory results can be obtained from 0.degree. C. to the vicinity of room temperature. DCC, as a condensing agent, is used in an amount of 1 to 20 equivalents, preferably 1 to 5 equivalents; and the solvent used for the reaction includes halocarbons such as dichloromethane, chloroform, carbon tetrachloride, and 1,2-dichloroethane, ethers such as ether, THF, DME, and dioxane; and dichloromethane and chloroform are preferable among these.

If a 6-amino body, that is included in those having the general formula (IIn) in which R.sup.3 is hydrogen, is condensed with a sulfonic acid derivative of general formula (IIId) in the steps shown in Chart 6, desirable results can be obtained by using a 6-amino body of general formula (IIng) (wherein R.sup.1, R.sup.2, R.sup.4, and G are as defined above) in which the phenolic hydroxy group is protected by a tri-substituted silyl group G, as is shown in Chart 10. This method is also applicable to condensation with a carboxylic acid derivative of general formula (IIIa), a formic acid derivative of general formula (IIIb), and an isocyanic acid or isothiocyanic acid derivative of general formula (IIIc). ##STR11##

In other words, after converting the 6-amino body to a compound of general formula (VIIInd) (wherein R.sup.1, R.sup.2, R.sup.4, R.sup.5, B and G are as defined above) by carrying out the first step in a similar way to that shown in Chart 8, the tri-substituted silyl group G is removed during the second step so as to obtain a compound general formula (Indp) (wherein R.sup.1, R.sup.2, R.sup.4, R.sup.5, and B are as defined above). For removing the silyl group in the second step, an acid such as hydrochloric acid, sulfuric acid, acetic acid, or hydrofluoric acid; a quaternary ammonium salt such as tetrabutylammonium fluoride, tetrabutylammonium chloride, and pyridinium hydrofluoride; or a base such as sodium hydroxide, potassium hydroxide, and potassium carbonate can be used; and in general, the removal of the silyl group can be sufficiently carried out using 1 to 20 equivalents, in particular 1 to 5 equivalents, of hydrochloric acid or tetrabutylammonium fluoride. Ethers such as THF, ether, DME, and dioxane, halocarbons such as dichloromethane and chloroform, acetonitrile, and the like are used as the reaction solvent; and THF is preferable among these. The reaction can be conducted at a temperature ranging from -20.degree. C. to 100.degree. C. and, in general, satisfactory results can be obtained at room temperature.

Among the compounds of general formula (I), a 6-amino body of general formula (Ine) (wherein R.sup.1, R.sup.2, R.sup.3, R.sup.4, R.sup.5, and B are as defined above) in which A is --NR.sup.4 --CH.sub.2 -- can be obtained by reducing a 6-amide body of general formula (Ina) shown in Chart 6 using a metal hydride reductant, as is shown in Chart 11. ##STR12##

A metal hydride compound having strong reducing power such as lithium aluminum hydride, diisobutyl aluminum hydride, aluminum hydride, lithium borohydride, or diborane can be used as the metal hydride reductant; and 1 to 20 equivalents, in particular, 1 to 5 equivalents, of diborane is preferably employed. When lithium aluminum hydride, lithium borohydride, or diborane is used, an ether such as THF, DME, ether, or dioxane can be used as the solvent; and THF is preferable. When diisobutyl aluminum hydride or aluminum hydride is used, an aromatic hydrocarbon such as benzene or toluene is preferably employed. The reaction can be conducted at a temperature ranging from -40.degree. C. to 120.degree. C. and preferably 0.degree. C. to 80.degree. C. When R.sup.3 of the 6-amide body having the general formula (Ina) is hydrogen, more preferable results can be obtained by the following method: the 6-amide body is converted to a 6-amino body, in which a tri-substituted silyl group G has been introduced to the phenolic hydroxy group according to the above method shown in Chart 5 and which has a general formula (Inag) (wherein R.sup.1, R.sup.2, R.sup.4, R.sup.5, B, and G are as defined above); the resultant is converted to a 6-amino body of general formula (Ineg) (wherein R.sup.1, R.sup.2, R.sup.4, R.sup.5, B, and G are as defined above) by the above reduction step; and then the tri-substituted silyl group G is removed according to the method shown in Chart 5.

Among compounds having the corresponding general formulae (Ia), (Ib), (Ic), and (Id) shown in Chart 1, in each of which E is O, a compound having a general formula (Ioa) (wherein R.sup.1, R.sup.2, R.sup.3, R.sup.5 and B are as defined above), a compound having a general formula (Iob) (wherein R.sup.1, R.sup.2, R.sup.3, R.sup.5, B, and Z are as defined above), a compound having a general formula (Ioc) (wherein R.sup.1, R.sup.2, R.sup.3, R.sup.5 and B are as defined above), and a compound having a general formula (Iod) (wherein R.sup.1, R.sup.2, R.sup.3, R.sup.5 and B are as defined above) can be obtained by condensation of a 6-hydroxy body of general formula (IIo) (wherein R.sup.1, R.sup.2, and R.sup.3 are as defined above) with: a carboxylic acid or a derivative thereof having the general formula (IIIa) (wherein B and R.sup.5 are as defined above); a formic acid derivative having the general formula (IIIb) (wherein Z, B and R.sup.5 are as defined above); an isocyanic acid or isothiocyanic acid derivative having the general formula (IIIc) (wherein B and R.sup.5 are as defined above); a sulfonic acid derivative having the general formula (IIId) (wherein B and R.sup.5 are as defined above); or the like. The condensation reaction can be carried out in accordance with the methods used for obtaining the compounds of general formulae (Ina), (Inb), (Inc), and (Ind), in each of which E is NR.sup.4, as is shown in Chart 6. ##STR13##

If a 6-hydroxy body of general formula (IIop) (wherein R.sup.1, R.sup.2, and R.sup.4 are as defined above) included in those having the general formula (IIo) in which R.sup.3 is hydrogen is used in the steps shown in Chart 12, the phenolic hydroxy group of the 6-hydroxy body occasionally reacts with a carboxylic acid derivative of general formula (IIIa), a formic acid derivative of general formula (IIIb), and an isocyanic acid or isothiocyanic acid derivative of general formula (IIIc) to give a compound having the corresponding general formulae (VIIIoa), (VIIIob), and (VIIIoc) (wherein R.sup.1, R.sup.2, R.sup.5, B, and Z are as defined above) shown in Charts 13 to 15; therefore, after conducting the first step in a similar manner to that shown in Chart 12, an alkali treatment is carried out as the second step to obtain the target compounds. ##STR14##

The above second step can be conducted in accordance with the methods employed for obtaining the compounds of general formulae (Inap), (Inbp), and (Incp) shown in Charts 7 to 9. However, solvolysis of the 6-position occasionally occurs and, in such a case, the reaction temperature is lowered or the reaction time is shortened.

If a 6-hydroxy body, that is included in those having the general formula (IIo) in which R.sup.3 is hydrogen, is condensed with a sulfonic acid derivative of general formula (IIId) in the steps shown in Chart 12, preferable results can be obtained by using a 6-hydroxy body of general formula (IIog) (wherein R.sup.1, R.sup.2, and G are as defined above) in which the phenolic hydroxy group is protected beforehand by a tri-substituted silyl group G, as is shown in the steps shown in Chart 16. This method is also applicable to condensation with a carboxylic acid derivative of general formula (IIIa), a formic acid derivative of general formula (IIIb), and an isocyanic acid or isothiocyanic acid derivative of general formula (IIIc). ##STR15##

In other words, after converting the 6-hydroxy body to a compound of general formula (VIIIod) (wherein R.sup.1, R.sup.2, R.sup.5, B and G are as defined above) by carrying out the first step in a similar way to that shown in Chart 8, the tri-substituted silyl group G is removed during the second step so as to obtain a compound of general formula (Iodp) (wherein R.sup.1, R.sup.2, R.sup.5, and B are as defined above). The removal of the silyl group can be conducted in accordance with the method employed for obtaining the above compound of (Indp) shown in Chart 10.

In practice, a free base obtained from the above steps can be formed into a salt with a pharmacologically acceptable acid according to the following method: The obtained free base is dissolved or suspended in a solvent, precipitated as a solid or crystals by adding an acid, and then collected by filtration; and if precipitation does not occur by adding an acid, a less polar solvent is added or the solvent is replaced with a less polar solvent to achieve precipitation; or the solution is evaporated to dryness after forming a salt. If an organic solvent is left as the resultant of one of the above methods, the resultant may be rendered to an aqueous solution to be freeze-dried, followed by drying under reduced pressure. Solvents used for dissolving or suspending the base include: water; alcohols such as methanol, ethanol, and isopropyl alcohol; halocarbons such as dichloromethane and chloroform; ethers such as ether, THF, DME, and dioxane; esters such as ethyl acetate and methyl acetate; and mixtures thereof; with methanol, ethanol, isopropyl alcohol, ethyl acetate, chloroform, chloroform-methanol, water-methanol, and water-ethanol being preferable. Ether, ethyl acetate, and the like are preferably used to precipitate a solid. Although an equivalent amount of acid is desirable, 1 to 10 equivalents of acid may be used if the excess acid can be removed from the resulting salt by washing. Furthermore, the acid may be added as it is, or after being appropriately dissolved in one of the above solvents. For example, hydrochloric acid can be added as concentrated hydrochloric acid, a 1N aqueous solution, a saturated solution in methanol or a saturated solution in ethyl acetate; and tartaric acid can be added as a solid, an aqueous solution, or a methanol solution. In some cases, desirable results can be obtained by cooling in a water bath or an ice bath, since the temperature of the reaction system is occasionally raised by the heat of neutralization due to the salt formation.

Trans-2-cyclopropylmethyl-4a-(3-hydroxyphenyl)-6.beta.-(3,4-dichlorophenyla cetamido)decahydroisoquinoline 21 hydrochloride ##STR36##

In 5.2 ml of methylene chloride, 173 mg of crude trans-6.beta.-amino-2-cyclopropylmethyl-4a-(3-hydroxyphenyl)decahydroisoqu inoline 20 obtained in Example 20 was dissolved, then 0.24 ml (1.72 mmol) of triethylamine and 0.19 ml (1.22 mmol) of 3,4-dichlorophenylacetyl chloride were added thereto in that order while cooling in an ice bath followed by stirring for 2 hours at room temperature. Separation was carried out by addition of 8 ml of distilled water and 6 ml of chloroform followed by two aqueous-layer extractions, each with 6 ml of chloroform. The thus-obtained organic layers were dried over anhydrous sodium sulfate and evaporated. The thus-obtained residue was dissolved in 4 ml of methanol and mixed with 80 mg (0.579 mmol) of potassium carbonate followed by stirring for 30 min. at room temperature. Separation was then carried out by addition of 10 ml of distilled water and 15 ml of chloroform followed by two aqueous-layer extractions, each with 8 ml of chloroform. The organic layers were combined, dried over anhydrous sodium sulfate and evaporated so that the resulting residue was purified using silica-gel chromatography (15 g of silica-gel; chloroform saturated with ammonia/methanol=20/1) to obtain 84 mg of a free base of the title compound (36% yield, 5 steps from 17). The free base was dissolved in 2 ml of methanol, a hydrogen chloride/methanol solution was added thereto until the pH thereof reached 4, and then the resultant was evaporated to dryness. The resulting residue was dissolved in 1 ml of methanol and mixed with an excess amount of ether to precipitate hydrochloride to obtain 80 mg (89% yield from the free base) of the title compound.

Cultured-Neurocyte Protective Effect against Glutamic Acid Toxicity

It is known that delayed cerebral-neuronal death is induced if blood flow to the brain is transiently stopped by transient ischemia, anoxia, hypoglycemia, or trauma [T. Kirino, Brain Research, 239, 57 (1982).]. The excitatory toxicity of excitatory neurotransmitters, such as glutamic acid, which is excessively released when associated with ischemia is considered as the cause of the neurocyte damage [S. M. Rotherman and J. W. Olney, Trends in Neuroscience, 10, 299 (1987).]. A compound which protects neurocytes from the cytotoxicity of glutamic acid will be promising as a preventive and therapeutic agent for cerebral ischemic diseases, cerebral neurocyte disorder, and dementia. The following method is employed as an in vitro evaluation system of the protective effect.

Under sterilized conditions, fetuses were taken from female Wistar rats 18 to 19 day-pregnant and the brains thereof were obtained by opening their cranial portions. The brains were placed in an ice-cold L-15 medium to microscopically separate the cerebral cortexes. After being cut into small pieces, the cerebral cortexes of approximately 30 rats were suspended in a mixture of 10 ml of a 0.25% trypsin solution and 0.2 ml of a 0.01% DNase solution to be cultured at 37.degree. C. for 30 min. Then, immediately after addition of 2 ml of serum, the resultant was centrifuged at 1,200 rpm for 2 min. to separate a sediment. To the sediment, 7 ml of a DF medium (prepared by addition of 20 nM of transferrin, 5 .mu.g/ml of insulin, 20 nM of progesterone, 60 nM of selenite, 50 U/ml of penicillin, and 50 U/ml of streptomycin to an equivalent admixture of Dulbecco modified Eagle medium and F-12 medium) was added to prepare a cell suspension which was pipetted 20 times using a 10 ml plastic pipette followed by filtration using a nylon mesh (pore size of 43 .mu.m) to obtain isolated cells. The resulting isolated cells were diluted to 6.0.times.10.sup.5 cells/ml with the DF medium, inoculated in a polylysine-precoated culture plate having 48 wells at 500 .mu.l per well, and cultured at 37.degree. C. in the presence of 5% CO.sub.2 for 1 day. The medium was changed with fresh DF medium on the second day, and 10 .mu.l of a 0.5M glutamic acid solution in distilled water is added to each of the wells (the final concentration of the glutamic acid was 10 mM), and the cells were cultured for further 24 hours at 37.degree. C. in the presence of 5% CO.sub.2. Each of the subject compounds was dissolved in distilled water, 10% or 100% DMSO, or 10% methanol and then a 5 .mu.l aliquot was added to each well immediately before addition of glutamic acid. The enzymatic activity of lactate dehydrogenase (LDH) which leaked into the medium from the damaged cells was measured as an index of the neurocyte damage. With respect to each of the subject compounds, LDH leakage at the respective concentrations was measured and a dose-response curve was obtained by a modified Cochran-Armitige method to obtain the 50% effective dose (ED.sub.50) of each subject compound. The results are shown in Table 1.

As a result, it became apparent that the compounds of the invention protected neurocytes from the cytotoxicity of glutamic acid.

Infarction Suppression Effect in Rat Middle Cerebral Artery Occlusion Model

Remarkable cerebral edema accompanied with severe cerebrovascular lesions appears in the acute stage of human cerebral infarction. It is well known that the cerebral infarction becomes significantly more severe if blood flow restarts in the acute stage of cerebral infarction. Corresponding to development of the lesion from the infarction area to surrounding tissues, the patient's life is seriously affected besides motor and mental functional loss in the conditions of the acute stage of cerebral infarction. A middle cerebral artery occlusion (MCAO; Middle Cerebral Artery Occlusion) model in Wistar rats using emboli with threads is well known as an experimental cerebral ischemia model in which clinical potency of a medicine can be accurately evaluated conforming to clinical conditions of human cerebral infarction [J. Koizumi, Japan Journal of Stroke, 8, 1 (1986)]. This MCAO model was employed as an in vivo evaluation system for evaluating the suppression effect of the compounds of the present invention on infarction development and was conducted according to the following method:

Under 1.0% halothane anesthesia induced by ether, the cervical region of each 10-week old rat was excised at center to expose the furcation of the right carotid while paying attention not to damage the vagus nerve. Centering around the furcation of the right carotid, the common carotid and the external carotid were separated from the surrounding tissues, each of them was ligated with 6-0 floss (Eto K.K.), and another floss was wound around the origin of the internal carotid so as to ligate and fix after inserting the embolus into the carotid. The common carotid was then incised to insert the ebolus toward the internal carotid to approximately 15 to 16 mm, and the proximal terminal of a nylon thread of the embolus was ligated and fixed to the internal carotid with the above mentioned floss. Due to the above procedure, the tip of the embolus exceeded the furcation of the middle cerebral artery, entered into the anterior cerebral artery to approximately 1 to 2 mm, and the entrance of the middle cerebral artery was occluded by the embolus body (made of a resin) for 2 hours. To reopen, the embolus with a thread was pulled away so as to restart the blood flow to the middle cerebral artery. Each of the subject compounds was intraperitoneally administered 1 hour before occlusion and 1 hour after reopening. Four days after the occlusion-reopening, each rat was systematically perfused with a saline from the heart and the brain was removed. After cooling each of the obtained brains with iced-water for 5 min., 7 coronary slices, taken at 2.0 mm intervals, of the cerebrum were prepared. Each slice was stained with TTC (triphenyltetrazolium chloride) and fixed with a neutral 5% formalin buffer solution, then the infarction area of the right cerebral hemisphere was measured by an image analyzer (Olympus) so as to evaluate the infraction expressed as a volume (mm3). The resulting infraction volume was compared with that of a control group to calculate the infarction suppression ratio. The results are shown in Table 2.

TABLE 2 ______________________________________ Infarction Suppression Ratio in Rat MCAo Model Infarction suppression ratio (%) Dose (mg/kg) Compounds 0.03 0.3 3 ______________________________________ 1 32 13 23 8 26 43 32 9 28 7 10 19 21 7 11 5 33 12 64 48 23 23 ______________________________________

As a result, it became apparent that, by protecting the cerebral neurocytes from various types of damage associated with the onset of cerebral ischemia, the compounds of the present invention suppressed the development of infarction and prevented the pathological conditions of cerebral infarction from worsening.

Analgesic Activity Test by Acetic Acid-Induced Writhing Method

For this experiment, 5-week old ddY mice were employed. A 0.6% aqueous acetic acid solution was intraperitoneally administered to each of the mice at 0.1 ml/10 g body weight to evaluate the analgesic activity by employing the number of writhing reactions occurring over a 10 min.-period starting from 10 min. after administration as an index. Each of the subject compounds was subcutaneously administered to the back of each mouse 15 min. before the acetic acid administration. The results are shown in Table 3.

Antitussive Effect Evaluation Using Capsaicin Induced Cough Model in Rat

Coughing was induced such that capsaicin (60 .mu.M) which had been rendered as aerosol using an ultrasonic nebulizer was sent to the cap covering the head of the rat through a silicone tube by an artificial respirator to be inhaled by the rat. The respirator sent 10 ml of air per time at a rate of 70 times per min.

Capsaicin was inhaled for 5 min. at 270 min. before administering a medicine, during which period cough induction was confirmed. Thirty min. after administering a test drug rats inhaled capsaicin for 5 min. to measure the number of coughs induced during this period. The antitussive effect was evaluated using the ratio of suppression to the number of coughs before applying a drug, which ratio was obtained from the number of coughs before and after applying a drug. Capsaicin was dissolved in a saline. Each of the test drugs was dissolved in 10% DMSO water and intraperitoneally applied. The effect of the drugs were expressed such that the dose exhibiting a 50% cough suppression ratio was indicated as the ED.sub.50 value. The results are shown in Table 4.
