Description: TECHNICAL FIELD This invention relates to a pyrimidine derivative having both of an excellent selective acetylcholinesterase-inhibiting activity and an excellent selective A type monoamine oxidase-inhibiting activity and useful as an antidepressant and an agent for curing senile dementia, and a salt thereof. BACKGROUND ART In senile dementia, acetylcholine in a brain is lacked so that an acetylcholinesterase-inhibiting agent has been studied. For example, as an agent for curing dementia, there have been disclosed 1-benzyl-4-[(5,6-dimethoxy-1-indanon)-2-yl]methylpiperidine, etc. in Japanese Provisional Patent Publication No. 79151/1989 and 1-benzyl-4-[2-(4-pyrrolidinobenzoyl)ethyl]piperidine, etc. in Japanese Provisional Patent Publication No. 173867/1991 (US 5,177,087). However, senile dementia is generally accompanied with symptoms such as depression, lowering of volition, etc. so that various symptoms of senile dementia cannot be ameliorated sufficiently only by an acetylcholinesterase-inhibiting agent. On the other hand, depression is related to monoamine (noradrenaline, serotonin), and as an antidepressant having an A type monoamine oxidase-inhibiting activity, there has been known, for example, 4-(4-cyanoanilino)-5,6-dihydro-7H-cyclopenta[d]pyrimidine as disclosed in Japanese Provisional Patent Publication No. 203072/1982 (US 4,450,162). The present inventors have studied for many years in order to develop a medicine having both of a selective acetylcholinesterase-inhibiting activity and a selective A type monoamine oxidase-inhibiting activity and therefore having a further improved curing effect as an agent for curing senile dementia, and consequently found that a pyrimidine derivative having a specific structure has selective inhibiting activities to both enzymes, to accomplish the present invention.

(wherein R 3 , R 6 , R 7 , Z and p have the same meanings as described above) (wherein R 3 , R 7 and p have the same meanings as described above) The condensation reactions of [Preparation process 7-1] and [Preparation process 7-2] are carried out by the same methods as described above in [Preparation process 6-1] and [Preparation process 6-2], and the deprotection reactions are carried out in the same manner as in [Preparation process 4-1] and [Preparation process 4-2], by suitably selecting a known method of using an acid, an alkali or hydrogen reduction, etc. Also, the N-alkylation reaction by the compound (XII) is carried out by the same methods as described above in [Preparation process 4-1] and [Preparation process 4-2], and the reduction reactions of the compounds (XVI'a), (XVI'b), (XVIII'a) and (XVIII'b) can be carried out by the same methods as described above in [Preparation process 6-1] and [Preparation process 6-2]. (wherein R 3 , R 6 and p have the same meanings as described above and R 9 represents a protective group such as a t-butoxycarbonyl group, a benzyloxycarbonyl group, an acetyl group, a trifluoroacetyl group and a benzoyl group) (wherein R 3 , R 9 and p have the same meanings as described above) In [Preparation process 8-1] or [Preparation process 8-2], the compound (XXIIa), (XXIId), (XXIVa) or (XXIVd) is prepared by subjecting the compound (XXI) or (XXIII) with the compound (VIII) or (IX) in a 1- to 5-fold molar amount, preferably a 1- to 2-fold molar amount to condensation reaction in a solvent in the presence of a strong base. R 9 as the protective group is not particularly limited so long as it is stable under these reaction conditions, and preferred are a t-butoxycarbonyl group, a benzyloxycarbonyl group, an acetyl group, a trifluoroacetyl group, a benzoyl group, etc. As the solvent to be used, there may be mentioned ethers such as diethyl ether, diisopropyl ether, tetrahydrofuran, dioxane, etc.; aliphatic and aromatic hydrocarbons such as pentane, hexane, cyclohexane, benzene, toluene, etc.; and aprotic polar solvents such as hexamethylphosphoric acid triamide, dimethyl sulfoxide, etc. Also, a mixture of these solvents may be used. As the strong base to be used, preferred are alkyl lithiums such as n-butyl lithium, t-butyl lithium, etc.; alkali metal amides such as lithium diisopropylamide, lithium ditrimethylsilylamide, sodium amide, etc.; and alkali metal hydrides such as sodium hydride, potassium hydride, etc. The amount to be used is generally a 1- to 5-fold molar amount, preferably a 2- to 3-fold molar amount based on the compound (XXI) or (XXIII). The reaction temperature is -70 to 100 °C, preferably the reaction is carried out in the range of -70 to 50 °C. The dehydration reactions of [Preparation process 8-1] and [Preparation process 8-2] are generally carried out by suitably selecting from various known methods used when an olefin is synthesized from an alcohol. There may be mentioned, for example, a dehydration method under acidic conditions using an inorganic acid such as hydrochloric acid, sulfuric acid, phosphoric acid, etc.; or an organic acid such as p-tolunesulfonic acid, benzenesulfonic acid, etc., or a dehydration method in the coexistence of a dehydrating agent such as thionyl chloride, phosphorus oxychloride, methanesulfonic acid chloride, methanesulfonic anhydride, acetic anhydride, etc. and an organic base such as pyridine, picoline, lutidine, 1,8-diazabicyclo[5.4.0.]-7-undecene, triethylamine, etc. Particularly when the protective group R 9 is unstable under acidic conditions, the latter method is preferred. In the above dehydration reactions, as in the examples of the compounds (XXIIe) and (XXIIf), and (XXIVe) and (XXIVf), isomers having the double bond at different positions may be produced. These may be separated and used or may be used as a mixture when they are used for the reduction reactions. The reduction reactions of [Preparation process 8-1] and [Preparation process 8-2] are carried out by the same methods as described above in [Preparation process 3-1] and [Preparation process 3-2]. By deprotecting the above compounds (XXIIa), (XXIIb), (XXIIc), (XXIId), (XXIIe), (XXIIf), (XXIIg), (XXIVa), (XXIVb), (XXIVc), (XXIVd), (XXIVe), (XXIVf) and (XXIVg), the compounds (IVe), (IVa), (IVb), (IVf), (IVc), (IVg), (IVd), (VIe), (VIa), (VIb), (VIf), (VIc), (VIg) and (VId) are prepared, respectively. The deprotection reactions are carried out by the same methods as described above in [Preparation process 4-1] and [Preparation process 4-2]. (wherein R 3 , R 6 , R 7 , R 9 , Z and p have the same meanings as described above) (wherein R 3 , R 6 , R 7 , R 9 , Z and p have the same meanings as described above) In [Preparation process 9-1] and [Preparation process 9-2], the condensation reactions, dehydration reactions and reduction reactions are carried out by the same methods as described in [Preparation process 8-1] and [Preparation process 8-2]. R 7 and R 9 as protective groups may be different or may be the same. The respective compounds obtained in the respective reactions of [Preparation process 9-1] and [Preparation process 9-2] are supplied to the deprotection reactions, respectively. In this case, by suitably selecting the kinds of the two protective groups R 7 and R 9 or suitably selecting deprotection conditions, either one of R 7 and R 9 can be selectively removed. Also, both of them can be removed simultaneously. The selections of these R 7 and R 9 and deprotection conditions can be carried out by referring to literatures, for example, T.W. Greene, "Protective Groups in Organic Synthesis" John Wiley & Sons. The compounds (XXVa), (XXVIa), (XXVb), (XXVIb), (XXVc), (XXVIc), (XXVd), (XXVId), (XXVe), (XXVIe), (XXVf), (XXVIf), (XXVg), (XXVIg), (XXVIIa), (XXVIIIa), (XXVIIb), (XXVIIIb), (XXVIIc), (XXVIIIc), (XXVIId), (XXVIIId), (XXVIIe), (XXVIIIe), (XXVIIf), (XXVIIIf), (XXVIIg) and (XXVIIIg) thus obtained can be converted into (XXIIa), (IVe), (XXIIb), (IVa), (XXIIc), (IVb), (XXIId), (IVf), (XXIIe), (IVc), (XXIIf), (IVg), (XXIIg), (IVd), (XXIVa), (VIe), (XXIVb), (VIa), (XXIVc), (VIb), (XXIVd), (VIf), (XXIVe), (VIc), (XXIVf), (VIg), (XXIVg) and (VId), respectively, by subjecting to alkylation using the compound (XII) (R 3 -Z) by the same methods as described above in [Preparation process 4-1] and [Preparation process 4-2], respectively. After completion of the reactions, the desired compounds of the respective reactions can be obtained by treating the reaction mixtures according to a conventional method and further can be purified by using a conventional purification means such as recrystallization, column chromatography, etc., if necessary. The compounds of the formula (I), the formula (II) and the formula (III) of the present invention are converted into desired salts according to a conventional method, if necessary. In the compounds of the formula (I), the formula (II) and the formula (III) thus prepared, optical isomers or geometric (cis and trans or E and Z) isomers may exist. In that case, by carrying out the above reactions by using starting compounds which are optically resolved or separated as desired, optical isomers or geometric isomers of the corresponding desired compounds can be obtained. Also, by treating a mixture of optical isomers or geometric isomers according to a conventional optical resolution method or separation method, the respective isomers can be obtained. In the formula (I), the formula (II) and the formula (III), all of optical isomers, geometric isomers and mixtures thereof are represented by the same formulae, but the respective isomers and mixtures thereof are included in the present invention as a matter of course.

The crude synaptosome fraction was prepared by homogenizing a rat cerebrum in a 0.32 M sucrose solution and, after centrifugal operation, suspending it in a 0.1 M phosphate buffer. The activity of acetylcholinesterase was measured by a partially modified method of the method of Ellman et. al. (Ellman, G.L. et al., Biochem. Pharmacol., 7 , 88 (1961)). That is, to the crude synaptosome fraction of the rat cerebrum suitably diluted with a 0.1 M phosphate buffer were added each compound to be tested, 5,5'-dithiobis(2-nitrobenzoic acid) (hereinafter referred to as DTNB) and acetylthiocholine as a substrate, and the mixture was incubated at 25 °C for a predetermined time. Subsequently, the amount of yellow anions formed by reaction of acetylthiocholine and DTNB was measured as absorbance at 410 nm to determine the activity of acetylcholinesterase. Enzyme activity-inhibiting rates were calculated from absorbances in the presence of the compounds to be tested having various concentrations based on absorbances in the absence of the compounds to be tested, with absorbance when reaction was carried out in the absence of the substrate being defined as blank. IC 50 values were calculated by Hill analysis. Test example 2. Butyrylcholinesterase-inhibiting activity As an enzyme source, a rat serum was used. The activity of butyrylcholinesterase was measured by a partially modified method of the above method of Ellman et. al. That is, to the rat serum suitably diluted with a 0.1 M phosphate buffer were added each compound to be tested, DTNB and butyrylthiocholine as a substrate, and the mixture was incubated at 25 °C for a predetermined time. Subsequently, the amount of yellow anions formed by reaction of butyrylthiocholine and DTNB was measured as absorbance at 410 nm to determine the activity of butyrylcholinesterase. Enzyme activity-inhibiting rates were calculated from absorbances in the presence of the compounds to be tested having various concentrations based on absorbances in the absence of the compounds to be tested, with absorbance when reaction was carried out in the absence of the substrate being defined as blank. IC 50 values were calculated by Hill analysis. Test example 3. A type and B type monoamine oxidase-inhibiting activity As an enzyme source, a rat cerebrum homogenized in a 0.1 M phosphate buffer was used. The activities of monoamine oxidases were measured by a partially modified method of the method of Da Prada et al. (Da Prada, M. et al., J. Pharmacol. Exp. Ther., 248 (1), 400 (1989)). That is, the rat cerebrum homogenate suitably diluted with a 0.1 M phosphate buffer and each compound to be tested were preincubated at 37 °C for 30 minutes. Then, a substrate labeled with 14 C (5-hydroxytryptamine (5-HT) having a final concentration of 200 µM was used in measurement of the activity of A type monoamine oxidase, and β-phenylethylamine (β-PEA) having a final concentration of 20 µM was used in measurement of the activity of B type monoamine oxidase) was added to the preincubated mixture, and the mixture was incubated at 37 °C for a predetermined time. After the reaction was terminated by adding hydrochloric acid (final concentration; 1.2 M), the reaction mixture and a predetermined amount of an organic solvent (diethyl ether was used in measurement of the activity of A type monoamine oxidase, and heptane was used in measurement of the activity of B type monoamine oxidase) were vigorously stirred so that deaminated metabolites were extracted into the organic layer. After the mixture was separated into two layers by centrifugation, a part of the organic layer was mixed with liquid scintillation cocktail. Radioactivity extracted into the organic layer was measured by a liquid scintillation counter to calculate the enzyme activity. Inhibiting rates were calculated from enzyme activities in the presence of the compounds to be tested having various concentrations based on enzyme activities in the absence of the compounds to be tested, with absorbance when reaction was carried out in the absence of the homogenate being defined as blank. IC 50 values were calculated by Hill analysis. The results of Test examples 1 to 3 are shown in Table 3.
