MORPHINAN DERIVATIVE AND MEDICINAL USE

Abstract: A morphinan derivative represented by general formula (1) or a pharmacologically acceptable acid addition salt thereof, an analgesic and diuretic containing the same as the active ingredient, and a process for producing the same The invention compound has potent analgesic and diuretic activities as a highly selective κ-opioid agonist, thus being useful as an analgesic and diuretic.

Description: The present invention relates to an analgesic and diuretic having for its active ingredient a morphinan derivative or pharmacologically acceptable acid salt thereof. Morphine has long been known as a powerful analgesic having a morphinan skeleton, and is widely used even at present. However. this drug has serious side effects that present clinical problems, including inducement of drug dependence, having action that suppresses respiration and action that suppresses smooth muscle movement (constipation). Thus, there is a need for a powerful analgesic that acts on the central nervous system and that also can be used safely. JP-B-41-018826 discloses a series of 3-methoxy, 6α-[di(C 1-2 alkyl) or cyclic secondary] amino-14-hydroxy morphinan derivatives having analgesic properties (though at that time, in 1966, the various mechanisms of such activity, discussed below, were unknown). In addition, it has also been reported that drugs that act on opioid receptors effect urination (J.D. Leander, J. Pharmacol. Exp. Ther., 227, 35 (1983)), and thus, the effective use of that action is also desired. The existence of the opioid receptors has been clearly established as being involved in analgesic action on the central nervous system. moreover, it is known that these receptors may be classified into the three types, µ, δ and κ. In addition, σ receptors are also known to demonstrate psychotomimetics. For example, Dykstra et al, J. Pharmacol. Exp. Ther, (1987), 242(2) , 421 in a study of the effects of kappa opioids in rhesus monkeys contrast this behaviour with µ-selective compounds such as β-funaltrexamine (β-FNA), i.e. 3,14-dihydroxy-4,5α-epoxy-6α-[trans-3-(methoxycarbonyl) acrylamido]-17-cyclopropylmethyl morphinan. Corresponding 6α- and 6β-N-methyl derivatives, again µ-selective compounds, and their preparation via the 6-methylamino compound, are described by Mohamed et al, J. Med. Chem., (1986), 29 , 1551. Morphine agonists, generally regarded as µ-receptors, are also disclosed in GB-A-2175898. This discloses 14-(optionally substituted) alkyl morphinan derivatives having at the 6α- or 6β-position the abovementioned trans-3-(methoxycarbonyl) acrylamido group or an amino, (C 1-3 alkyl) amino, phenylamido or benzene sulphonamido group. Those agonists having affinity for κ-receptors or δ-receptors have been shown to have strong analgesic activity, while not demonstrating serious side effects that present clinical problems, such as drug dependence, action that suppresses respiration and action that suppresses smooth muscle movement, that are observed in the case of morphine and so forth, which are µ-receptor agonists. In addition, the psychomimetics observed in existing κ-receptor agonists is reported to be caused by the affinity to σ-receptors. Moreover, κ-receptor agonists do not demonstrate cross tolerance with µ-receptor agonists such as morphine. Analgesics free of such side effects have a high degree of usefulness since they can be applied in not only the control of pain in patients having post-operative pain and cancer patients suffering from cancer, but can also be widely applied for general pain. In addition, the absence of cross tolerance indicates that these analgesics are effective even in patients that have developed tolerance to analgesics such as morphine. Namely, the object of the present invention is to provide a κ-receptor agonist or δ-receptor agonist that has powerful analgesic action while not having serious side effects like those of morphine, not having cross tolerance with morphine and so forth, and not demonstrating any affinity whatsoever for σ-receptors. In addition, another object of the present invention is to provide a useful diuretic that takes advantage of the effects of opioid action drugs on urination. As a result of earnest studies to solve the above-mentioned problems, we have found that the morphinan derivative represented by the general formula (I) is a compound that demonstrates analgesic action and diuretic action having the excellent characteristics described above.

Furthermore, the compounds of the present invention include the (+), (-) and (±) forms. The compounds of general formula (I) of the present invention can be obtained, specifically, according to the methods described below. Among the compounds represented by the general formula (I) of the present invention, those wherein A is -N(R 4' )C(=Y)-, -N(R 4' )C(=Y)Z- or -N(R 4' )SO 2 - (wherein Y represents O or S, Z represents O, NH or S, and R 4' is as previously defined) can be obtained, specifically, according to the methods described below. In general, as shown in Chart 1, the compounds can be obtained by condensing a carboxylic acid derivative represented by the general formula (III) (wherein B and R 5 are as previously defined), a formic acid derivative represented by the general formula (IV) (wherein Z, B and R 5 are as previously defined), an isocyanic acid or isothiocyanic acid derivative represented by the general formula (V) (wherein B and R 5 are as previously defined) or a sulfonic acid derivative represented by the general formula (VI) (wherein B and R 5 are as previously defined), with a 6-amino or 6-hydroxy compound represented by the general formula (II) (wherein R 1 , R 2 , R 3 and R 8 are the same as previously defined, and E represents NHR 4' (wherein R 4' is as previously defined) or OH). The 6-amino and 6-hydroxy compound used in this condensation can be obtained, specifically, by the processes described below. As shown in Chart 2, a 6α-amino compound represented by the general formula (IIaα1) (wherein R 1 , R 2 , R 3 and R 8 are as previously defined and R 4' represents a straight-chain or branched alkyl group having 1-5 carbon atoms or an aryl group having 6-12 carbon atoms) is obtained by mixing a 6-keto compound represented the general formula (VIIa) (wherein R 1 , R 2 , R 3 and R 8 are as previously defined) and a primary amine represented by the general formula (VIII) (wherein R 4 is as previously defined) in a solvent and hydrogenating in the presence of suitable amounts of acid and metal catalyst, or reducing with a metal hydride reducing agent in the presence of acid. The hydrogenation reaction is more preferable in order to obtain the α-amino isomer with high selectivity. However, although the ratio varies according to the substrate, in the case of reduction using a metal hydride reducing agent, both the α form and β isomer are obtained simultaneously. Thus, this method is preferable in that it makes it possible to obtain a compound having the desired stereochemistry by using ordinary separation and purification techniques. In addition, the method in which the amine is obtained is also useful in the case of substrates having functional groups, such as olefins and so on, that react under hydrogenation conditions. In the case of reduction using a hydrogenation reaction, 1-30 equivalents, and preferably 1-10 equivalents, of amine are used. Although any solvent including alcohols such as methanol and ethanol, ethers such as THF, ether, DME and dioxane, or aromatic hydrocarbons such as benzene and toluene, can be used as a reaction solvent as long as it is inert under hydrogenation conditions, alcohols are preferably used, with methanol used particularly preferably. Although any acid including inorganic acids such as hydrochloric acid, hydrobromic acid, sulfuric acid and phosphoric acid, or organic acids such as sulfonic acids including methanesulfonic acid and p-toluenesulfonic acid, benzoic acid, acetic acid or oxalic acid, can be used as long as it forms a salt with an amine, hydrochloric acid, sulfuric acid and methanesulfonic acid are preferably used. Normally, the use of hydrochloric acid in an amount of 1 equivalent less than the total amount of base yields satisfactory results. These acids can also be added to a reaction system after converting the substrate and reaction agents into salts in advance. Although all catalysts, including platinum catalysts such as platinum oxide and platinum hydroxide, palladium catalysts such as palladium hydroxide and palladium-carbon, and nickel catalysts such as Raney nickel, that are normally used in hydrogenation reactions can be used as a metal catalyst, platinum catalysts, and particularly platinum oxide, are used preferably. The reaction temperature is -30°C to 80°C, and preferably -10°C to 50°C, and the hydrogen pressure is 1-100 atmospheres and preferably 1-30 atmospheres. However, carrying out the reaction at room temperature and atmospheric pressure normally yields preferable results. When reducing with a metal hydride, 1-30 equivalents, and preferably 1-15 equivalents, of amine are used. Although alcohols solvents such as methanol and ethanol, ethers such as THF, ether, DME and dioxane, or aromatic hydrocarbons such as benzene and toluene, can be used for as a solvent, alcohols are used preferably, with methanol used particularly preferably. Although any acid, including inorganic acids such as hydrochloric acid, hydrobromic acid, sulfuric acid and phosphoric acid, and organic acids such as sulfonic acids including methanesulfonic acid, p-toluenesulfonic acid, benzoic acid, acetic acid and oxalic acid, may be used in the reaction provided that it normally forms a salt with amlnes, hydrochloric acid, sulfuric acid and methanesulfonic acid are preferably used. In addition, these acids may also be added to the reaction system after converting the substrate and reaction agents into salts in advance. The metal hydride reducing agent used is that which allows the reaction to be carried out relatively stably in the presence of acid, examples of which include sodium borohydride, sodium cyanoborohydride, zinc borohydride, sodium triacetoxyborohydride, tetramethylammonium triacetoxyborohydride and boranepyridine, with sodium cyanoborohydride used particularly preferably. Although the reaction can be carried out at a reaction temperature of -30°C to 100°C and preferably -10°C to 50°C, satisfactory results can normally be obtained at room temperature. As shown in Chart 3, a 6β-amino compound represented by the general formula (IIaβ2) (wherein R 1 , R 2 , R 3 and R 8 are as previously defined, and R 4' represents a straight-chain or branched alkyl group having 1-5 carbon atoms or an aryl group having 6-12 carbon atoms) can be obtained from a 6-keto compound represented by the general formula (VIIb) (wherein R 1 , R 2 , R 3 and R 8 are as previously defined) with the 3 steps described below. Step 1 involves the obtaining of an iminium intermediate represented by the general formula (X) (wherein R 1 , R 2 , R 3 , R 4 and R 8 are as previously defined) by reaction of a keto compound with a secondary amine compound having at least one benzyl substituent group represented by the general formula (IX) (wherein R 4' is as defined above) in the presence of acid. It is desirable that the reaction be carried out while removing water produced either by azeotropic distillation or in the presence of a dehydrating agent. 1-30 equivalents, and preferably 1-10 equivalents, of secondary amine are used. Although any acid, including inorganic acids such as hydrochloric acid, hydrobromic acid, sulfuric acid and phosphoric acid, or organic acids such as sulfonic acids including methanesulfonic acid and p-toluenesulfonic acid, benzoic acid, acetic acid and oxalic acid, can be used in the reaction as long as it forms a salt with amine, hydrochloric acid, sulfuric acid, methanesulfonic acid and benzoic acid are used preferably, with hydrochloric acid and benzoic acid used particularly preferably. A method wherein these acids are added to the system after converting the substrate and reaction agents into salts in advance is also preferably carried out. Moreover, in the case of carrying out the reaction in the presence of a weak acid, there are cases wherein preferable results are obtained if a strong acid such as inorganic acids such as hydrochloric acid, hydrobromic acid, sulfuric acid and phosphoric acid, or sulfonic acids such as methanesulfonic acid, p-toluenesulfonic acid and campher-sulfonic acid especially a strong acid such as p-toluenesulfonic acid is added as an acid catalyst. Examples of reaction solvents that can be used include ethers such as THF, ether, DME and dioxane, halocarbons such as dichloromethane and chloroform, aromatic hydrocarbons such as benzene, toluene and xylene, esters such as ethyl acetate and methyl acetate, or mixtures thereof. When using a conventional Dean-Stark water separator for the purpose of removing water, solvents are used preferably that have excellent azeotropic efficiency and water separation efficiency, such as aromatic hydrocarbons such as benzene and toluene. In this case, the mixing of a solvent such as ethyl acetate, THF or the like, for the purpose of lowering the azeotropic temperature, in amounts that do not lower water separation efficiency may provide preferable results. Although a temperature of 40-200°C, and preferably 50-150°C, can be considered as a reaction temperature, satisfactory results can be obtained at a reaction temperature of 50-130°C. In addition, it has also been found that a new method is effective wherein a dehydrating agent is packed into a Soxhlet type extractor followed by continuous removal of water. Although any of the solvents mentioned above can be used as a solvent in this case, ethers, esters and aromatic hydrocarbons, and particularly THF, DME, ethyl acetate, benzene and toluene, are preferably used. Although examples of dehydrating agents include molecular sieves and inorganic dehydrating agents such as anhydrous calcium sulfate, anhydrous copper sulfate, anhydrous sodium sulfate, anhydrous magnesium sulfate and calcium chloride, molecular sieves are used particularly preferably. The amount used is 1-100 times, and preferably 1-30 times as calculated from their water retentivity and the amount of moisture theoretically produced. Although a temperature of 40-200°C, and preferably 50-150°C, can be considered as a reaction temperature, satisfactory results are obtained at a reaction temperature of 50-120°C. In addition, a method can also be carried out wherein the reaction is allowed to proceed by directly adding dehydrating agent to the reaction system. Examples of dehydrating agents include molecular sieves, inorganic dehydrating agents such as anhydrous calcium sulfate, anhydrous copper sulfate, anhydrous sodium sulfate, anhydrous magnesium sulfate and calcium chloride, or titanium compounds having dehydration ability such as tetraisopropoxytitanium and titanium tetrachloride. In this case also, an amount used is 1-100 times, and preferably 1-30 times as calculated from the water retentivity and the amount of moisture theoretically produced. Although a temperature of -80-100°C can be considered as a reaction temperature, satisfactory results are obtained at a reaction temperature of -30-50°C. Step 2 is a step involving conversion to a 6-N-alkyl-N-benzylamino compound represented by the general formula (XI) (wherein R 1 , R 2 , R 3 , R 4' and R 8 are as previously defined) by reducing with metal hydride reducing agent without isolating iminium salt. Although the same solvent used in step 1 may be used as is for the reaction solvent of this step, preferable results are obtained by reacting after mixing an alcohols such as methanol or ethanol, and particularly methanol. Naturally, the reaction may also be carried out with only alcohols such as methanol or ethanol after distilling off the reaction solvent of step 1 under reduced pressure. The reaction can be carried out with metal hydride reducing agent that is relatively stable under conditions in the presence of acid, such as sodium borohydride, sodium cyanoborohydride, zinc borohydride, sodium triacetoxyborohydride, tetramethylammonium triacetoxyborohydride and boranepyridine, particularly preferably sodium cyanoborohydride. The reaction is carried out a reaction temperature of -20-150°C, and preferably 0-120°C. The resulting 6-N-alkyl-N-benzylamino compound represented by the general formula (XI) (wherein R 1 , R 2 , R 3 , R 4' and R 8 are as previously defined) can also be obtained using a secondary amine by performing reductive amination using the metal hydride reducing agents of Chart 2. Moreover, if this step is performed using a corresponding secondary amine, the compound of general formula (I) can be obtained wherein A is -NR 4' -. Step 3 involves removing a benzyl group under reducing conditions to form a 6β-amino form (IIaβ2). In this step, reacting the substrate either after converting into a salt in advance using an inorganic acid such as hydrochloric acid, hydrobromic acid, sulfuric acid or phosphoric acid, or an organic acid such as sulfonic acids including methanesulfonic acid, p-toluenesulfonic acid or camphersulfonic acid, benzoic acid, acetic acid, oxalic acid or phthalic acid, and preferably hydrochloric acid or phthalic acid, or adding suitable amount of these acids prior to the reaction, yields favorable results. Since there are cases in which a resulting secondary amine salt can be purified as a crystal depending on the acid, selection of acid is important. For example, when phthalic acid is used with a compound wherein R 1 is a cyclopropylmethyl group, R 2 and R 3 are hydroxy groups, R 4' is a methyl group and R 8 is a hydrogen atom, a crystalline salt is obtained that is easily purified. Although any solvent such as alcohol-based solvents such as methanol and ethanol, ethers such as THF, ether, DME and dioxane, and organic hydrocarbons such as benzene and toluene, can be used as a reaction solvent provided it is inert under hydrogenation conditions, alcohols are used preferably, with methanol used particularly preferably. Although any catalyst that is used in normal hydrogenation reactions, such as, platinum catalysts such as platinum oxide and platinum hydroxide, palladium catalysts such as palladium hydroxide and palladium-carbon, and nickel catalysts such as Raney nickel, can be used as a metal catalyst, palladium catalysts, and particularly palladium-carbon, are particularly preferably used. The reaction temperature is -30 to 80°C, and preferably -10 to 50°C while hydrogen pressure is 1 to 100 atmospheres, and preferably 1 to 30 atmospheres. However, carrying out the reaction at room temperature and atmospheric pressure normally yields favorable results. In addition, when ammonium acetate is used in place of primary amine in the reductive amination reaction shown in Chart 2, when dibenzylamine is used in the method shown in Chart 3, or after converting ketone into oxime using the method described in the literature (J. Med. Chem., 27, 1727 (1984)), a primary amine can be obtained by reducing with borane or under hydrogenation conditions. This primary amine can be converted into a secondary amine by effecting the acylation and reduction of step 2. This is also useful as an alternative route for obtaining the secondary amine. Among the 6-amino or 6-hydroxy compound synthesized in the above method, particularly a compound wherein R 3 is a hydrogen atom, is obtained by methods similar to those shown in Charts 2, 3, 4 and 5, using as a starting material a 3-dehydroxy-6-keto compound represented by the general formula (VIIe) (wherein R 1 , R 2 and R 8 are as previously defined), obtained by using as a substrate a 3-hydroxy-6-keto compound represented by the general formula (VIIc) (wherein R 1 , R 2 and R 8 are as previously defined, according to the scheme shown in Chart 6. In addition, an intermediate, wherein R 3 is a siloxy group, can be obtained by methods similar to those shown in Charts 2, 3, 4 and 5, by using for as a starting material a 3-siloxy-6-keto form represented by the general formula (VIIf) (wherein R 1 , R 2 and R 8 are as previously defined, provided that G represents an alkylsilyl group), obtained from a 3-hydroxy-6-keto compound (VIIc) by the scheme shown in Chart 7. Namely, as shown in Chart 6, the first step for obtaining a 3-dehydroxy-6-keto compound represented by the general formula (VIIe) (wherein R 1 , R 2 and R 8 are as previously defined) is a step wherein trifluoromethane sulfonic anhydride is caused to act on a phenolic hydroxyl group in the presence of a base to form a trifrate form represented by the general formula (VIId) (wherein R 1 , R 2 and R 8 are as previously defined,). Although solvents such as halocarbons such as dichloromethane and chloroform, ethers such as THF, ether, DME and dioxane, and amines having large steric hindrances that can be used as solvents such as 2,6-lutidine and diisopropylethylamine, can be considered for use as a reaction solvent, halocarbons, and particularly dichloromethane, are preferably used. Although tertiary amines such as triethylamine, diisopropylethyl amine and proton sponge, as well as pyridine, 2,6-lutidine and imidazole are used as a coexisting base, 2,6-lutidine is preferably used. Although the reaction can be carried out at -30-50°C, satisfactory results can be normally attained at a temperature of 0°C to room temperature normally yields. Step 2 is a step wherein a trifrate form is reduced with formic acid in the presence of phosphorous ligand and a base using a palladium catalyst. Although amines usable as solvents such as triethylamine and diisopropylethylamine, ethers such as THF, ether, DME and dioxane, aromatic hydrocarbons such as benzene and toluene, and aprotic dipolar solvents such as DMF and DMSO are used for the reaction solvent, DMF is particularly preferably used. Although zero-valent complexes such as tetrakuistriphenylphosphine palladium and bisbenzylideneacetone palladium, and bivalent complexes such as palladium acetate and palladium chloride are frequently used for the palladium catalyst, palladium acetate is used normally. Although monodentate phosphines such as trimethylphosphine, triethylphosphine, triphenylphosphine and tris-o-toluphosphine, and bidentate phosphines such as bis-(diphenylphosphino)methane, 1,2-bis-(diphenylphosphino) ethane, 1,3-bis-(diphenylphosphino)propane and 1,1'-bis-diphenylphosphinoferrocene, are used as a phosphorous ligand, 1,1'-bis-diphenylphosphinoferrocene is particularly preferably used. Although amines such as triethylamine and diisopropylethylamine, and inorganic salts such as silver carbonate, sodium acetate and potassium acetate, are used as a base used in the reaction, triethylamine is preferably used. The reaction is carried out at a reaction temperature of 0-150°C, and satisfactory results are normally obtained at a room temperature to 80°C. As shown in Chart 7, a 3-hydroxy-6-keto form represented by the general formula (VIIc) (wherein R 1 , R 2 and R 8 are as previously defined) may be reacted with silylchloride in the presence of a base to obtain a 3-siloxy-6-keto form represented by the general formula (VIIf) (wherein R 1 , R 2 and R 8 are as previously defined and G represents an alkylsilyl group). Although trimethylsilylchloride, triphenylsilylchloride, t-butyldimethylsilylchloride and diphenylmethylsilylchloride are mentioned as silylchlorides, t-butyldimethylsilylchloride is preferably used. Although tertiary amines such as triethylamine, diisopropylethylamine and proton sponges, as well as pyridine, dimethylaminopyridine and imidazole are used as a base, imidazole is preferably used. Although halocarbons such as dichloromethane, chloroform, carbon tetrachloride and 1,2-dichloroethane, ethers, such as ether, THF, DME and dioxane, and pyridine are used as a solvent, dichloromethane is preferably used. The reaction can be carried out within a range of -80-100°C, and preferable results are obtained particularly in the vicinity of 0°C to room temperature. Although the reaction can be carried out in 5-300 minutes, since there are cases in which 6th position ketone groups are also enolsilylated when reaction time is lengthened particularly with respect to compounds wherein ..... is a single bond, a reaction time of 5-60 minutes is preferable. As shown in Chart 8, compounds wherein X is NR 4' can be obtained by condensing a 6-amino form represented by the general formula (IIa) (wherein R 1 , R 2 , R 3 and R 8 are as previously defined, and R 4' represents a straight-chain or branched alkyl group having 1-5 carbon atoms or an aryl group having 6-12 carbon atoms), obtained by the methods shown in Charts 2 and 3, with a carboxylic acid and carboxylic acid derivative represented by the general formula (III) (wherein B and R 5 are as previously defined), or with a formic acid derivative represented by the general formula (IV) (wherein Z, B and R 5 are as previously defined), or with a isocyanic acid or isothiocyanic acid derivative represented by the general formula (V) (wherein B and R 5 are as previously defined) or with a sulfonic acid derivative represented by the general formula (VI) (wherein B and R 5 are as previously defined) Condensation with a carboxylic acid derivative can be performed by reacting a 6-amino form with an acid chloride or acid anhydride that reacts in the presence of a base, or by reacting with carboxylic acid itself using, for example, N,N'-dicyclohexylcarbodiimide (abbreviated as DCC), 1,1'-carbonyldiimidazole, or bis-(2-oxo-3-oxazolidinyl)phosphinate chloride (abbreviated as BOPC). Acid chloride or acid anhydride is used in an amount of 1-20 equivalents, and preferably 1-5 equivalents. Although halocarbons such as dichloromethane, chloroform, carbon tetrachloride and 1,2-dichloroethane, ethers such as ether, THF, DME and dioxane, pyridine, water or a mixture of these are used as reaction solvents, when using acid chloride, chloroform or a mixed solvent of THF and water is used preferably. In the case of using acid anhydride, pyridine is preferably used both as base and solvent. Although organic bases such as tertiary amines including triethylamine, diisopropylethylamine and proton sponges, pyridine, dimethylaminopyridine and imidazole, and inorganic bases such as potassium carbonate, sodium carbonate, sodium bicarbonate, sodium hydroxide and potassium hydroxide are used as bases, when using chloroform as the solvent, trimethylamine is normally used in an amount of 1-20 equivalents, and preferably 1-5 equivalents. In the case of using a mixed solvent of THF and water, the use of potassium carbonate, sodium carbonate or sodium bicarbonate in an amount of 1-20 equivalents, and preferably 1-5 equivalents, provides satisfactory results. The reaction can be carried out within a range of -80-100°C, and preferable results are obtained particularly at a temperature of from 0°C to room temperature. In the case of using DCC as a condensing agent, an amount of 1-20 equivalents preferably 1-5 equivalents is used.

Although ethers such as ether, THF, DME and dioxane, and halocarbons such as dichloromethane, chloroform, carbon tetrachloride and 1,2-dichloroethane are used as reaction solvents, THF is particularly preferably used. The reaction can be carried out within a range of -20-120°C, and a temperature in the vicinity of room temperature to 100°C is particularly preferable. In the case of using BOPCl as a condensing agent, it is used in an amount of 1-20 equivalents, and preferably 1-5 equivalents. Examples of solvents used for the reaction (solvent) include halocarbons such as dichloromethane, chloroform, carbon tetrachloride and 1,2-dichloroethane, and ethers such as ether, THF, DME and dioxane, though dichloromethane and chloroform are particularly preferably used. Although organic bases such as tertiary amines including triethylamine, diisopropylethylamine, proton sponge and N-ethylpiperidine as well as pyridine, dimethylaminopyridine and imidazole are used as coexisting bases, N-ethylpiperidine in an amount of 1-20 equivalents, and preferably 1-5 equivalents is particularly preferably used.

Condensation with a formic acid derivative can be performed by reacting a 6-amino form with 1-20 equivalents and preferably 1-5 equivalents of an acid chloride that reacts in the presence of base. Although halocarbons such as dichloromethane, chloroform, carbon tetrachloride and 1,2-dichloroethane, ethers such as ether, THF, DME and dioxane, water or mixtures of these solvents are used as reaction solvents, chloroform and a mixed solvent of THF and water are particularly preferably used. Although organic bases such as tertiary amines including triethylamine, diisopropylethylamine and proton sponge, pyridine, dimethylaminopyridine and imidazole, and inorganic bases such as potassium carbonate, sodium carbonate and sodium bicarbonate are used as bases, triethylamine in an amount of 1-20 equivalents, and preferably 1-5 equivalents provides satisfactory results when chloroform is used as a solvent, while potassium carbonate, sodium carbonate and sodium bicarbonate used in an amount of 1-20 equivalents, and preferably 1-5 equivalents, normally provides favorable results when a mixed solvent of THF and water is used as a solvent. The reaction can be carried out within a range of -80-100°C, and preferable results are obtained from 0°C to the vicinity of room temperature. Condensation with an isocyanic acid or isothiocyanic acid derivative can be performed by reacting 1-20 equivalents, and preferably 1-5 equivalents, of a corresponding isocyanate ester with a 6-amino form. Although halocarbons such as dichloromethane, chloroform, carbon tetrachloride and 1,2-dichloroethane, and ethers such as ether, THF, DME and dioxane are used as reaction solvents, chloroform is particularly preferably used. The reaction can be carried out within a range of -80-100°C, and preferable results are obtained from 0°C to the vicinity of room temperature. Condensation with a sulfonic acid derivative can be performed by reacting 1-20 equivalents, and preferably 1-5 equivalents, of the corresponding sulfonate chloride with a 6-amino form in the presence of base. Examples of bases that are used include tertiary amines such as triethylamine, diisopropylethylamine and proton sponges, as well as pyridine, dimethylaminopyridine and imidazole. Although halocarbons such as dichloromethane, chloroform, carbon tetrachloride and 1,2-dichloroethane, ethers such as ether, THF, DME and dioxane, and pyridine are used as bases, pyridine is particularly preferably used as both base and solvent. The reaction can be carried out within a range of -80-100°C, and preferable results are obtained from 0°C to the vicinity of room temperature in particular. In the case of compounds wherein R 3 is a hydroxy group in particular, since there are cases in which phenolic hydroxyl groups may react simultaneously, after carrying out step 1 in the same manner as shown in Chart 8, as shown in Charts 9-11 with carboxylic acid derivative, formic acid derivative and isocyanic acid or isothiocyanic acid derivative, the target compound can be obtained by performing alkaline treatment for step 2. Examples of solvents used for a reaction solvent of step 2 include water, alcohols such as methanol and ethanol, ethers such as ether, THF, DME and dioxane, or mixed solvents of those solvents. When solubility is inadequate, halocarbons such as dichloromethane and chloroform can be suitably added. Examples of bases used include inorganic bases such as potassium carbonate, sodium carbonate, sodium bicarbonate, sodium hydroxide and potassium hydroxide. Normally, 1-20 equivalents, and preferably 1-10 equivalents, of potassium carbonate, sodium hydroxide and so forth are used preferably. The reaction can be carried out within a range of -80-100°C, and favorable results are obtained from 0-50°C in particular. When condensing compounds wherein R 3 is a hydroxy group with sulfonic acid derivative, as shown in Chart 12, preferable results are obtained by using a 3-siloxy-6-amino form, wherein phenolic hydroxyl groups are protected in advance with silylether groups and so forth, represented by the general formula (IIc) (wherein R 1 , R 2 , R 4' , R 8 and G are as previously defined). Naturally, the following method can also be applied to condensation with a carboxylic acid derivative, formic acid derivative and isocyanic acid or isothiocyanic acid derivative. Namely, this method involves removing silyl groups after carrying out step 1 in the same manner as shown in Chart 8. Although quaternary ammonium salts such as tetrabutylammonium fluoride, tetrabutylammonium chloride and pyridinium hydrofluoride, or acids such as acetic acid, hydrochloric acid, sulfuric acid and hydrofluoric acid, are used for removal of silyl groups in step 2, normally 1-20 equivalents, and preferably 1-5 equivalents, of tetrabutylammonium fluoride are used. Although ethers such as THF, ether, DME and dioxane, halocarbons such as dichloromethane and chloroform, and acetonitrile are used as solvents, THF is particularly preferably used. Although the reaction can be carried out at -20-100°C, satisfactory results can normally be obtained at room temperature. In addition, a 6-amino form represented by the general formula (Im) (wherein R 1 , R 2 , R 3 , R 4' , B, R 5 and R 8 are as previously defined), in which A is -NR 4' -, is obtained by reducing an amide form represented by the general formula (Ie') (wherein R 1 , R 2 , R 3 , R 4' , R 5 R 8 and B are as previously defined) using a metal hydride reducing agent. Examples of reducing agents used include metal hydride compounds having a strong reducing activity such as lithium aluminum hydride, aluminum diisobutylaluminumhydride, aluminum hydride, lithium borohydride and diborane, 1-20 equivalents, and preferably 1-5 equivalents of diborane are particularly preferably used. Ethers such as THF, DME, ether and dioxane are used preferably as a solvent when using lithium aluminum hydride, lithium borohydride or diborane, with THF being used particularly preferably. Aromatic hydrocarbons such as benzene and toluene are used preferably as a solvent when diisobutylaluminumhydride or aluminum hydride are used. The reaction can be carried out within a range of -40 to 100°C, and a temperature from 0°C to the vicinity of room temperature is preferable. The free base obtained in the above steps can be converted into the salts with pharmacologically acceptable acids specifically by the methods shown below. Namely, a resulting free base is dissolved or suspended in a solvent followed by addition of acid and filtering of the precipitated solid or crystal, or in the case of not precipitating, a solvent of lower polarity is added, or the solvent is substituted with a solvent of lower polarity and filtering after precipitation. Alternatively, concentration and drying are performed after forming a salt. However, in the case organic solvent remains in these methods, drying under reduced pressure may be performed after freeze-drying in an aqueous solution. Examples of solvents used to dissolve or suspend the above free 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, or their mixed solvents, while preferable examples include methanol, ethanol, isopropyl alcohol, ethyl acetate, chloroform, chloroform-methanol, water-methanol, and water-ethanol. Preferable examples of solvents used for precipitating solid include ether and ethyl acetate. Although it is desirable that an equivalent amount of acid be added, when it is possible to remove excess acid after washing the resulting salt, 1-10 equivalents may be used. In addition, acid may be added as is or suitably dissolved in the above-mentioned solvents and then added. For example, hydrochloric acid can be added in the form of concentrated hydrochloric acid, 1 N aqueous solution, a saturated methanol solution or a saturated ethyl acetate solution, while tartaric acid can be added in the form of a solid, an aqueous solution or a methanol solution. At the time of salt formation, since the temperature of the system may rise due to the heat of neutralization, there are cases in which favorable results are obtained if a water bath or ice bath is used. As a result of in vitro and in vivo pharmacological testing, the compounds of the present invention represented by the general formula (I) are known to have strong analgesic and diuretic activity as an opioid κ-agonist, and it became clear that it can be expected to be used as a useful analgesic and diuretic. In addition, based on the properties of κ-agonists, it is also possible to use this compound as a hypotensive and sedative. Moreover, it was also found that the compounds of the present invention also include agonists highly selective for δ-receptors, thus suggesting the possibility of their use as an immunoenhancer, anti-HIV agent and so forth. At the time of clinical use of the analgesic or diuretic of the present invention, it may be used as in the form of a free base or its salt, or suitably mixed with vehicles such as stabilizer, buffer, diluent, isotonic agents and preservatives. Examples of administration forms include injection preparations; oral preparations such as capsules, powders, granules and syrup, transintestinal administration in the form of suppositories; or topical administration in the form of ointments, creams and plasters. It is desirable that the analgesic of the present invention contain 1-90% by weight, and preferably 30-70% by weight of the above-mentioned active ingredient. Although the amount used is suitably selected according to symptoms, age, body weight and administration method, the adult dose as the amount of active ingredient in the case of an injection preparation is 0.0001 mg - 1 g per day, and 0.005 mg - 10 g per day in the case of an oral preparation. In both cases, administration may be performed in a single dose or divided among several administrations.

[Example 92] 17-cyclopropylinethyl-3,14β-dihydroxy-4,5α-epoxy-6α-(N-methyl-3,4-difluorophenylacetamido)morphinan· hydrochloride 105 128 mg of 3,4-difluorophenylacetic acid and 131 mg of carbonyl diimidazole were dissolved in 2.5 ml of anhydrous tetrahydrofuran. After refluxing while heating for 30 minutes, the solution was cooled to room temperature. A solution of 200 mg of 17-cyclopropylmethyl-4,5α-epoxy-3,14β-dihydroxy-6α-methylaminomorphinan 4 dissolved in 13 ml of anhydrous tetrahydrofuran was added to the reaction solution followed by refluxing while heating for 1 hour. After cooling to room temperature, the reaction solution was concentrated and the resulting residue was dissolved in 16 ml of methanol and stirred for 1 hour following the addition of 1 ml of 1 N aoueous sodium hydroxide. The reaction system was then concentrated followed by the addition of 40 ml of ethylacetate to the residue and sequential washing with 25 ml of water and 25 ml of saturated brine. After drying with anhydrous sodium sulfate, the organic layer was concentrated to obtain 439 mg of crude product. This was then recrystallized from ethylacetate to obtain 190 mg of the free base of the target compound. The mother liquor was then purified with silica gel column chromatography (25 g chloroform/methanol = 19/1) to obtain 177 mg of the free base of the target compound. The free base obtained in this manner was then dissolved in a mixed solvent of chloroform and methanol, and this solution was concentrated after adding methanol solution of hydrochloride to adjust to pH 4. The residue was re-precipitated with ether and filtered to obtain 176 mg of the target compound (yield: 57%). mp 194-208°C (decomposition, diethylether) NMR (400 MHz, DMSO-d 6 ) δ 0.31-0.43 (1H, m), 0.43-0.53 (1H, m), 0.53-0.64 (1H, m), 0.64-0.76 (1H, m), 0.99-1.12 (1H, m), 1.12-1.28 (1H, m), 1.28-1.45 (1H, m), 1.45-1.67 (2H, m), 1.86-2.03 (1H, m), 2.35-2.50 (1H, m), 2.59-2.77 (1H, m), 2.80 (0.6H, s), 2.88-3.18 (3H, m), 2.96 (2.4H, s), 3.18-3.39 (2H, m), 3.78 (1.6H, s), 3.88 (0.4H, s), 3.91 (1H, d, J=6.8 Hz), 4.49 (0.2H, m), 4.62 (1H, d, J=3.4 Hz), 4.97 (0.8H, dt, J=14.2, 3.4 Hz), 6.25 (0.8H, br s), 6.56 (0.2H, br s), 6.58 (1H, d, J=7.8 Hz), 6.73 (1H, d, J=7.8 Hz), 7.03-7.18 (1H, m), 7.25-7.45 (2H, m), 8.82 (1H, br s), 9.32 (1H, s) IR (KBr) υ 1620, 1560, 1520, 1460, 1278, 1172, 1120, 1036, 774 cm -1 .

Electrical stimulus was performed at 0.1 Hz for 5.0 ms by means of ring-shaped platinum electrodes located above and below. Tissue contractions were recorded on a polygraph using an isometric transducer. Initially, the test drug was cumulatively added to a concentration at which specimen contractions caused by electrical stimulus were suppressed by 50% to calculate the IC 50 value. Then after adequately washing with nutrient solution and the contraction reaction stabilized, naloxone, a µ agonist, or norBNI, a κ agonist, were added and the test compound was again cumulatively added after roughly 20 minutes. The Ke value was calculated using the following calculation formula from the difference in the efficacies of both agonists. Ke = [Conc. of added agonist]/(IC 50 ratio - 1) IC 50 ratio = IC 50 in the presence of agonist/IC 50 in the absence of agonist As a result, when the ratio between the Ke value (µ) and Ke value (κ) was taken, Ke(µ)/Ke(κ) = 4063 .
