Pyrimidine derivatives

BACKGROUND OF THE PRESENT INVENTION
The present invention relates to novel substituted pyrimidine derivatives which have an amide bond in the 5-position, processes for producing the derivatives, and pharmaceutical compositions containing the pyrimidine derivatives for the treatment and/or prevention of arteriosclerosis or hyperlipidemia.
In recent years, arteriosclerosis has been recognized as a rapidly increasing disease in circulatory disorder, and is also given much attention as a basal lesion for serious disease. Arteriosclerosis causes various ischemic diseases or bleeding, for example, the ischemic heart disease due to coronary atherosclerosis, such as angina pectoris and myocardial infarction the cerebrovascular disease due to cerebrovascular arteriosclerosis, such as cerebral infarction and cerebral apoplexy, the optic nerve atrophy and hydrocephalia due to compression by cerebral arteriosclerosis, nephrosclerosis due to kidney arteriosclerosis, and aneurysm and arteriosclerosis obliterans due to stenosis in the lumen of the aorta and peripheral artery. Such diseases and occasionally fatal. It is generally said that hypertension, hyperlipidemia, smoking, obesity, diabetes and the like contribute to arteriosclerosis, especially pultaceous atherosclerosis. It is also known that cholesterinosis, calcinosis and foam cells derived from macrophages or vascular smooth muscle cells appear in sclerosis lesions. However, a clear mechanism for arteriosclerosis has not been elucidated, hence sufficient treatment and/or prevention of arteriosclerosis have yet to be established. In order to treat these diseases, drugs which can decrease serum cholesterol has been developed. Colestyramine and melinamide, which are inhibitors of cholesterol absorption from the intestine, and clofibrate, which partially facilitates cholesterol metabolism, are typical examples. As the mechanism of transport of serum cholesterol is gradually understood, drugs which regulate the balance of serum cholesterol level have also been developed. However, these drugs have not been effective in the prevention or treatment of arteriosclerosis. The development of drugs which lower the serum cholesterol level by the inhibition of cholesterol biosynthesis (HMG-CoA reductase inhibitors, squalene epoxidase inhibitors) has also been progressed. On the other hand, drugs that are antagonistic to platelet derived growth factor (PDGF) which inhibit the proliferation of vascular smooth muscle cells, and drugs which prevent macrophage infiltration to the arterial wall and the formation of foam cell, are also given much attention as a remedy for arteriosclerosis. Especially, in the stud of arteriosclerosis lesions, macrophage which transform into foam cell after scavenging degenerated lipids has been recognized as an essential factor which links hyperlipidemia to arteriosclerosis. It has also been said that the acyl-CoA cholesterol acyltransferase (ACAT) plays an important role on the onset of arteriosclerosis. That is to say, ACAT facilitates dietary cholesterol absorption from the intestine by esterification of free cholesterol at the intestinal mucosa. Furthermore, it is indicated that ACAT contributes to the formation of deposit of cholesterol esters derived from the above macrophage in the arterial wall. Therefore, ACAT inhibitors have been expected to lowering the level of serum lipids, and have been used for the treatment and/or prevention of arteriosclerosis.
Until now, various kinds of drugs for the treatment of arteriosclerosis have been developed, and some compounds directed to ACAT inhibition are described in JP-A-60 41655 and JP-A-2 117651. However, the development of these compounds has been discontinued since some of the compounds did not exhibit significant efficacy in clinical studies, and others had adverse effects on the liver, despite the good effects in lowering serum cholesterol in the animal models.
Although JP-A-62 258366 and JP-A-3 120243 exhibit pyrimidineamide compounds as anti-arteriosclerotic agents with an inhibitory effect on ACAT, the structures of these compounds are distinguishable from those of the present invention, and only a portion of inhibitory activities on ACAT in a variety of animal cells in vitro is shown. Further, there is no disclosure about any toxicological study in connection with the compounds described in JP-A-62 25866 and JP-A-3 120243.
Under these circumstances, anti-arteriosclerotic agents which possess beneficial effects directly on the arterial wall with good clinical efficacy and high safety in Homo sapiens are desired.
SUMMARY OF THE INVENTION
An object of the present invention is to provide novel 5-(.omega.-substituted amino-alkanoyl amino)-pyrimidine derivatives, or salts or solvates or solvates of said salts thereof.
Another object of the present invention is to provide a process for producing the novel pyrimidine derivatives.
A further object .of the present invention is to provide pharmaceutical compositions for the treatment and/or the prevention of arteriosclerosis or hyperlipidemia which comprise the novel pyrimidine derivatives as active components.
Since the compounds of the present invention significantly prevent the accumulation of cholesteryl esters in macrophages and potently inhibit the microsomal ACAT activity from a variety of organs in vitro, these compounds are expected to exert beneficial effects directly on the atherosclerotic lesion. Further, the compounds of the present invention not only show significant hypolipidemic effect on high cholesterol diet feeding animals, but also have inhibitory activities on ACAT in microsomal fraction of human hepatoma cell line.
In addition, the compounds of the present invention have little toxicity and side effect on the liver and other organs that are apprehended with the former hypolipidemic drugs and/or ACAT inhibitor. It is therefore indicated that the compounds of the present invention are safe and beneficial for the treatment of arteriosclerosis itself and various maladies derived from arteriosclerosis, as such ischemic heart diseases caused by coronary atherosclerosis, such as angina pectoris and myocardial infarction, the cerebrovascular diseases caused by cerebrovascular arteriosclerosis, such as cerebral infarction and cerebral apoplexy, optic nerve atrophy and hydrocephalia caused by increased mechanical pressure in the region of cerebral arteriosclerosis, nephrosclerosis caused by arteriosclerosis of the kidney, aneurysm and arteriosclerosis obliterans caused by stenosis of the aorta and peripheral artery, sthenia of platelet aggregation, deep venous thrombosis, others; and hyperlipidemia, hypercholesterolemia, diabetes, variety of thrombosis, xanthoma and so on.

Moreover, instead of condensing reagents, the mixed anhydride method of using chloroformic ester and triethylamine, pyridine or N-methylmorpholine is useful for condensation.
When using DCC, DCC is added to a mixture of intermediates of the formula (II) and intermediates of the formula (III) at a temperature from approximately -20.degree. C. to room temperature, preferably under ice-cooling, in a halogenated hydrocarbon type solvent, such as methylene chloride, chloroform and dichloroethane. The reaction mixture is warmed to room temperature, and stirred for from 1 hr to 24 hrs to obtain compounds of the formula (I).
Moreover, a Mukaiyama reagent is useful as a condensing reagent, as described in Chemistry Letters, p1163 (1975). After addition of Mukaiyama reagent according to the above DCC method, the reaction is carried out at a suitable temperature, from ice-cooling condition to gentle reflux condition.
Process 2
Intermediates of the formula (V) are obtained by the condensation of intermediates of the formula (II) and intermediates of the formula (IV) according to Process 1 or by the reaction of intermediates of the formula (II) with activated acid derivatives, prepared from intermediates of the formula (IV), such as acid halides or acid anhydrides.
The reaction using an acid halide is carried out in organic solvents at a suitable temperature below the boiling point of the mixture, in the presence of a suitable acid scavenger.
A tertiary amine such as triethylamine, pyridine, diisopropylethylamine or dimethylaminopyridine is employed as an acid scavenger, and an inert solvent such as a halogenated hydrocarbon, for example methylene chloride, an ether-type solvent, for example tetrahydrofuran or dioxane, or an aromatic hydrocarbon, for example toluene, is employed as a solvent wherein methylene chloride is preferred.
Intermediates of the formula (V) can be converted to compounds of the formula (I) by the reaction with amine derivatives of the formula (VI) in the presence of an organic base such as diethylaniline.
In the case of the formula (I) pyrimidine derivatives having mercapto groups, obtained above, the mercapto groups can be converted to substituted mercapto groups by the reaction with a suitable alkyl halide, aryl halide and/or aralkyl halide in the presence of an acid scavenger such as the above-mentioned tertiary amine.
Further, hydroxyl groups of pyrimidine derivatives can be converted to several substituent groups according to the preparation shown in the following Process (i).
Furthermore, the protecting groups of reactive functional groups such as hydroxyl, mercapto or amino group can be removed by the methods described in "Protective Groups in Organic Synthesis, second edition" T. W. Greene and P. G. M. Wuts ed., published by John Wiley and Sons, 1991. These reactive groups also can be subsequently converted to several functional groups by above-mentioned methods.
Intermediates of the formula (III) are known compounds, or can be synthesized from known or commercially available intermediates and can be synthesized from halogenocarboxylic acid derivatives, preferably halogenocarboxylic acid esters, or acrylic acid derivatives, with amine derivatives of the formula (VI).
In the case of the synthesis from halogenocarboxylic acid esters, the intermediates of the formula (III) can be obtained by the reaction of amine derivatives of the formulae (VI) with halogenocarboxylic acid esters with or without the inert solvents described in Process 2, using an organic base such as pyridine, triethylamine, dimethylaminopyridine, diethylaniline, dimethylaniline, diazabicycloundecene (DBU), etc., or an inorganic base such as potassium carbonate etc. and then by the hydrolysis with an alkali hydroxide such as sodium hydroxide.
In the case of the synthesis from acrylic acid, the intermediates of the formula (III) can be obtained by the reaction of acrylic acid and amine derivatives of the formula (VI) in an aqueous solution at a temperature from room temperature to the reflux temperature of the reaction mixture, preferably reflux condition.
Compounds of the formula (II) are also known compounds, or can be synthesized from known or commercially available intermediates. The synthetic methods about many pyrimidine intermediates are described in the review of "The Pyrimidines" D. J. Brown ed., published by John Wiley and Sons, 1962.
The detailed synthetic methods are described below.
Process (i)
4,6-Dihydroxypyrimidine derivatives, as starting materials, can De synthesized from amidine derivatives, such as formamidine or acetamidine, urea or its O-alkyl derivatives, thiourea or its S-alkyl derivatives and guanidine or its alkyl derivatives and malonic acid diesteEs by well-known method. The obtained 4,6-Dihydroxypyrimidine derivatives with reactive functional groups, such as hydroxyl, mercapto and amino, at the 2-position can be protected by a suitable protecting group, such as benzyl or acetyl, if necessary. Further, pyrimidine derivatives with protected reactive functional group at the 2-position can be synthesized directly using derivatives such as S-benzylisothiourea, O-benzylisourea, or 1-acetylguanidine.
The thus obtained 4,6-dihydroxypyrimidine derivatives are converted to the corresponding 4,6-dihydroxy-5-nitropyrimidine derivatives by the reaction with suitable nitrating reagents, such as concentrated nitric acid, fuming nitric acid, alkyl nitrate, nitric oxide, nitronium tetrafluoroborate and nitronium trifluoromethansulfonate, preferably with fuming nitric acid in acetic acid. Furthermore, 5-nitropyrimidine derivatives can be synthesized directly from 2-nitromalonic esters.
Hydroxyl groups at the 4- and 6-positions of the obtained 5-nitropyrimidine derivatives can be converted to 4,6-dichloro- or 4,6-dibromo-pyrimidine. As chlorinating or brominating reagents, oxalyl chloride, thionyl chloride, phosphorus trichloride, phosphorus pentachloride, phosphorus oxychloride, or corresponding bromide can be used.
Various kind of substituents can be introduced into the 4 and 6 positions of 4,6-disubstituted-5-nitropyrimidine derivatives by the reaction with nucleophilic reagents, as shown in <reaction scheme 2> below.
The same substituent groups are introduced at the 4- and 6-positions by using over two equivalents of nucleophilic reagents, and a different substituent group is introduced at the 4-position from that at the 6-position by using an equivalent of different nucleophilic reagents one by one. As nucleophilic reagents, substituted amine, alcohol, phenol, or mercapto etc. can be used. In <reaction scheme 2>, X represents a halogen atom, and R.sup.1, R.sup.2 and R.sup.3 of each compounds have the same significance as defined in the formula (I). ##STR3##
The introduction of amino groups can be carried out with desired mono- and/or di-substituted amines in the presence of the acid scavengers described above. The reactions are carried out conventionally in non-solvent or in suitable inert solvents such as the above-mentioned ether-type solvents or halogenated hydrocarbons, at a suitable temperature, preferably from -20.degree. C. to room temperature, for 10 min. to 5 hrs.
The introduction of mercapto groups are carried out with sodium hydrosulfide in polar solvents, such as ethanol, methanol and dimethylformamide at a suitable temperature, preferably room temperature, for 1 hr to 10 hrs.
If necessary, the conversion from mercapto to alkylthio, arylthio or aralkylthio is carried out with alkyl halide, aryl halide or aralkyl halide using alkaline metal compounds, such as sodium hydride and alkoxide, or acid scavengers, such as the above-mentioned tertiary amines.
The substituted mercapto groups can directly be introduced by the reaction with sodium methylthiolate solution in an alcohol solvent, or with an alkyl mercaptane, an aryl mercaptane, an aralkyl mercaptane in an inert ether solvent such as cyclic- and dialkyl-ether, in the presence of as base, such as sodium hydride or alkoxide.
The synthesis of pyrimidine derivatives having an alkoxyl and/or phenoxy group can be carried out with an alkaline metal hydroxide in an alcohol, or a metal alkoxide or phenoxide, such as sodium alkoxide or phenoxide, in an alcoholic solvent.
Organometal reagents typically represented by Grignard reagents or lithium reagents, can be used as nucleophilic reagents to introduce alkyl and/or aryl groups. In the case of Grignard reagents, the reactions are carried out in above mentioned inert solvents or dimethylformamide, preferably in an ether-type solvent such as cyclic- or dialkyl-ether, without a catalyst or with metal catalysts such as 1,3-bis(diphenylphosphino)propane nickel cholride(Nidppp), 1,2-bis(diphenylphosphino)ethane nickel cholride(Nidppe), bis(triphenylphosphine)palladium chloride, palladium acetate, preferably Nidppp or Nidppe, at a suitable temperature, generally at reflux condition with heat, for 1 hr to 24 hrs.
The corresponding 5-aminopyrimidine intermediates of the formula(II) can be prepared by the-reduction of the 5-nitropyrimidine derivatives obtained above, using zinc in acetic acid, or tin chloride, tin powder or iron powder in hydrochloric acid, or a reductant such as hydrogen gas with suitable catalysts, such as Raney nickel or palladium-carbon in an alcohol, preferably zinc in acetic acid. Namely, the 5-nitropyrimidine derivatives are dissolved with acetic acid, and zinc powder is added to the mixture under ice-cooling. The mixture is reacted at a temperature from -20.degree. C. to the reflex temperature of the reaction mixture, preferably at room temperature, for 1 hr to 48 hrs, with stirring, to obtain the 5-aminopyrimidine intermediates of the formula
Thus in the obtained intermediates of formula (II), the compounds having halogeno groups at the 4 and 6 positions, if necessary, can be reacted with the above-mentioned nucleophilic reagents. The compounds having a mercapto group of the pyrimidine derivatives can be converted to the compound having a substituted mercapto group.
If necessary, the protecting group of reactive functional group, such as hydroxyl, mercapto and amino can be removed by the method described "Protective Groups in Organic Synthesis", Second Edition, T. W. Greene and P. G. M. Wuts ed., published by John Wiley and Sons, at an arbitrary step in above process.
Process (ii)
According to the following <reaction scheme 3>, 5-phenylazopyrimidine can be synthesized by reacting phenylazo-.beta.-keto esters prepared from .beta.-keto esters, typically malonate or acetoacetate, and diazonium salts prepared from aniline and sodium nitrite, and amidine derivatives, such as formamidine and acetamidine, urea and its O-alkyl derivatives, thiourea and its S-alkyl derivatives, and guanidine and its alkyl derivatives in organic solvents, such as an alcohol in the presence of bases such as sodium alkoxide, at a suitable temperature from room temperature to the boiling temperature of the reaction mixture, for 1 hr to 10 hrs.
4,6-Dihydroxypyrimidine derivatives can be obtained using malonic acid diesters as starting materials. ##STR4##
In the case of 4,6-dihydroxypyrimidine derivatives with reactive functional groups, such as hydroxyl, mercapto and amino at 2-position, the reactive functional groups can be protected by a suitable protecting group such as benzyl and acetyl etc., if necessary.
Further pyrimidine derivatives with protected reactive functional group at the 2-position, can be synthesized directly by using the derivatives of S-benzylisothiourea, O-benzylisourea, or 1-acetylguanidine.
5-Phenylazopyrimidine intermediates can be converted to 5-aminopyrimidine intermediates by electrolytic reduction in an acid solution, metal reduction using e.g. zinc, tin, nickel, or inorganic salts reduction using sodium hydrosulfite, preferably by the reduction using sodium hydrosulfite. The hydroxyl groups at 4(6)-position of 5-aminopyrimidine, obtained above, can be converted to several other substituent groups by the method shown in Process (i).
Process (iii)
The synthesis of pyrimidine having 6-alkyl, 6-aryl or 6-aralkyl group can be carried out directly by condensing .beta.-diketones, typically acetoacetic acid ester, with amidine derivatives, such as formamidine or acetamidine, urea and its O-alkyl derivatives, thiourea and its S-alkyl derivatives, and guanidine and its alkyl derivatives. This method is well-known as Pinner's pyrimidine synthesis, wherein the reaction is carried out under basic conditions, for example, sodium alkoxide etc. in an alcohol, at a suitable temperature, preferably in a reflux condition, for 1 hr to 24 hrs.
.beta.-diketone equivalents such as an acyl Meldrum's acid, diketene, diketene-acetone adduct(2,2,6-trimethyl-1,3-dioxin-4-one) can be used for pyrimidine synthesis under neutral conditions. In the case of pyrimidine derivatives with reactive functional groups, such as hydroxyl, mercapto, and amino at 2-position, the reactive functional groups can be protected by a suitable protecting group, such as benzyl or acetyl, if necessary. Further pyrimidine derivatives with a protected reactive functional group at 2-position, can be synthesized directly by using a derivative of S-benzylisothiourea, O-benzylisourea, or 1-acetylguanidine.
The obtained 2,6-disubstituted-4-pyrimidone derivatives Can be converted to substituted amino derivatives after halogenation according to the above-mentioned process. Then nitration and reduction at 5-position can convert the derivative to 5-aminopyrimidine intermediates of the formula (II).
Since the compounds of the present invention significantly prevent the ability of macrophages from accumulating cholesteryl esters, these compounds are expected to show an inhibitory effect against atherogenesis and/or the development of atherosclerotic lesion. Furthermore, the compounds potently inhibit the microsomal ACAT activity from a variety of organs in vitro. Indeed, these compounds are effective in reducing the intestinal absorption of dietary cholesterol and in inhibiting the synthesis and secretion of lipoproteins in the liver, resulting in hypolipidemic effect in experimental animals. Therefore, an obvious reduction of a risk factor for atherosclerosis can be expected. Not only do the pyrimidine derivatives and their salts of the present invention exert potent inhibition on the ACAT activity in microsomal fractions prepared from animal organs, but the derivatives also exert potent inhibition on the ACAT activity in those from human hepatoma cell line, HepG2, as compared with previous ACAT inhibitors. In addition, the compounds of the present invention possess quite low toxicity and side effect on the liver and other organs that are apprehended with the former hypolipidemic drugs and/or ACAT inhibitor.
Experimental Example will be illustrated by the pharmacological effects, toxicities, doses and directions for use of the compounds of the present invention.
Pharmacological effects of the compounds of the present invention are shown in more detail as follows.
Experimental Example 1

Experimental Examination 6
Acute toxicity.
The pyrimidine derivatives of the present invention were examined for acute toxicity by using male Wistar rats fasted over night aged 7 weeks old. After given orally the compounds of the Example 143 of the present invention at the single dose of 2 g/kg or the compounds of the Example 155, 196, 231, 232, 233, 240, 247, 260 and 262 of the present invention at the single dose of 1 g/kg, no lethal incident was observed over 7 days after the administration.
As mentioned above, it is clear that the compounds of the present invention possess a potent inhibitory effect on the accumulation of cholesteryl ester in macrophages in vitro and on ACAT in microsomal fractions of arterial wall and liver. These inhibitory activities on ACAT were more potent than a representative ACAT inhibitor, CL277082. Therefore, the compounds of the present invention are expected to exert beneficial effects directly on the atherosclerotic lesion. The compounds also show remarkable hypolipidemic effect on high cholesterol diet feeding rats and have inhibitory activity on ACAT in microsomal fraction of the human hepatoma cell line, HepG2. These compounds are accordingly expected to have a beneficial effect on the human hyperlipidemia and atherosclerosis. In addition, the compounds of the present invention have little toxicity and side effect on liver and other organs that are apprehended with the former hypolipidemic drugs and/or ACAT inhibitor. It is therefore indicated that the compounds of the present invention are safe and beneficial for the prevention and treatment of arteriosclerosis itself and various maladies derived from arteriosclerosis, such as (1) ischemic heart diseases caused by coronary atherosclerosis, such as angina pectoris and myocardial infarction etc., (2) the cerebrovascular diseases caused by cerebrovascular arteriosclerosis, such as cerebral infarction, cerebral apoplexy, cerebral thrombosis, transient ischemic attack and subarachnoid hemorrhage etc., (3) optic nerve atrophy and hydrocephalia caused by increased mechanical pressure in the region of cerebral arteriosclerosis, (4) nephrosclerosis caused by arteriosclerosis of the kidney, (5) aneurysm and arteriosclerosis obliterans caused by stenosis of the aorta and peripheral artery, (6) sthenia of platelet aggregation, (.7) deep venous thrombosis, and (8) others; hyperlipidemia, diabetes, variety of thrombosis, xanthoma and so on.
The compounds of the present invention may be in the form pharmaceutically acceptable salts. Typical examples of such salts of the-compounds include pharmaceutically acceptable salts with organic or inorganic acids, such as hydrochloric acid, hydrobromic acid, phosphoric acid, p-toluenesulfonic acid, methanesulfonic acid, salicylic acid, citric acid, fumaric acid, succinic acid, tartaric acid, oxalic acid, lactic acid and mandelic acid, or with acidic amino acids such as aspartic acid and glutamic acid.
The compounds of the present invention can be administered independently or can be mixed with appropriate pharmaceutically acceptable carriers or medium such as excipients, binders, lubricants, coloring agents, flavors, and optionally sterilized water, edible oils, non-toxic organic solvents or non-toxic solubilizers (for example, glycerin or propylene glycol), emulsifying agents, suspending agents (for example, Tween 80 or arabic gum), and can be prepared into the appropriate pharmaceutical compositions by appropriate selection and combination of the above compounds and carriers according to a conventional process.

Preparation of N-[4-mercapto-2-methyl-6-(N-phenyl-N-propylamino)pyrimidin -5-yl]-2-(N-phenyl-N-propylamino)acetamide
To a solution of the product obtained in EXAMPLE 68 (137 mg) and the product obtained in EXAMPLE 109 (116 mg) in methylene chloride (5 ml), N,N'-dicyclohexylcarbodiimide (134 mg) was added under ice-cooling and the solution was stirred for 1 hour at room temperature. The formed insoluble material was filtered off and the filtrate was diluted with 50 ml of ethyl acetate. The organic solution was washed with saturated sodium bicarbonate and saturated sodium chloride, dried over anhydrous sodium sulfate and then concentrated under reduced pressure. The residue was purifed by silica gel column chromatography (ethyl acetate:hexane=1:4-2:3) and followed by washing with ether to give 164 mg (73%) of the objective compound.

EXAMPLE 201
Preparation of N-(4,6-dimethoxy-2-methylpyrimidin-5-yl)-2-(N-phenyl-N-propylamino)acetamide
To a solution of the product obtained in EXAMPLE 109 (0.23 g) in methylene chloride (5 ml), 2-chloro-1-methylpyridinium iodide (0.47 g) and triethylamine (0.49 ml) were added under ice-cooling. After stirring for 40 minutes at room temperature, a solution of the product obtained in EXAMPLE 102 (0.20 g) in methylene chloride (1 ml) was added dropwise to the mixture under ice cooling. The reaction mixture was stirred at room temperature for 30 minutes and then refluxed for 1 hour. After cooling to room temperature, the mixture was diluted with water and extraction with ethyl acetate. The organic layers was washed with water and saturated sodium chloride in order and dried over anhydrous sodium sulfate and solvents ware removed under reduced pressure. The residue was purified by silica gel column chromatography (ethyl acetate:hexane=1:1) and followed by crystallization from ether-petroleum ether to give 0.18 g (44%) of the objective compound.
