3-Carbamoyl-2-Pyridone Derivative

TECHNICAL FIELD

The present invention relates to 3-carbamoyl-2-pyridone derivatives having an agonistic activity to the cannabinoid receptor, its pharmaceutical-compositions, and its medicine applications.

BACKGROUND ART

Cannabinoid (CB) was discovered as the main active substance contained in marijuana in 1960 and its main behavior was an activity in the central nervous system bringing about illusion, euphoria, sensory confusion of time and space, and the like by being ingested.

It has been found that a seven times transmembrane G protein bonded cannabinoid type 1 (CB1) receptor exists in the central nervous system such as the brain in 1990, and besides agonists to the receptor take part in the adjustment of a higher-order function of the brain by restrainedly controlling the neurotransmitter discharge with the signal transmission system in the cell such as controlling adenylate cyclase activity, controlling N— and P/Q types Ca 2⁺ channels, activating voltage gated K+ channel, and activating MAP kinase activity through the receptor, it has been also found that the receptor exists also in peripheral tissues and has minor activities in non-nervous systems such as an anti-inflammatory activity, and the alleviation of hypotonia bulbi and muscular spasm. Further, a cannabinoid type 2 receptor (CB2) was found to be distributed over immune tissues such as the spleen and agonists to this receptor were found to surpress an activation of immunocyte or inflammatory cells to exhibit an immunosuppressive activity, an anti-inflammatory activity and analgesic activity (Non-patent literature 1). From these facts, the application of agonists to the cannabinoid receptors to medicines has become to be examined widely.

As applications as medicines of agonists to the cannabinoid receptors, the medical treatment for an allergic disease of quinolone derivatives (Patent literatures 1, 2, 3, 4, and 5), 3,4-dihydroisoquinoline derivatives (Patent literature 6), pyridone derivatives (Patent literature 7), and further quinolone derivatives (Patent literature 8) have been described. Moreover, an anti-pruritic activity is disclosed in Patent literatures 10 and 11.

Itching is a kind of biological reaction, and peripheral itching and central itching are known. For example, sweet itchs including inflammatory reactions such as an edema, atopic dermatitis, hives, senile xerosis, and contact dermatitis are peripheral itching caused when nerve endings (itching receptors) of sensory nerve fibers existing in the epidermal-dermal junction are activated by a chemical, physical, or electric stimulus and the like. On the other hand, refractory pruritus such as systemic pruritus of a renal failure patient, which is derived from the hemodialysis, is thought to be central itching that is caused by an opioid peptide uniting with the receptor.

Medicines presently used as an anti-pruritus agent include, for example, diphenhydramine and crotamiton. The former is not effective in other itching though it is effective in the edema and hives that histamine took part as an antihistaminic. Moreover, though the latter adds anti-inflammatory activity by adding a steroid drug and is used as ointment for itching of eczema and the like, the action mechanism is uncertain.

By the way, atopic dermatitis is a cutaneous disease being accompanied by very strong pruritus and skin inflammation in the background of the atopic disposition and accompanied by the decrease in the barrier function, and the wax and wane are repeated. At present, as for medicines that soothe the inflammation and the effectiveness is proven, there are only two kinds, that is, steroids for internal use and for external application, and calcineurin inhibitory medicines that are called the immunosuppressive activity agents or immunoregulation agents for external use such as tacrolimus and eridale. However, there are severe faults such as the existence of steroid refractory patients, various systemic and locality side effects, and rebounds in the steroid. Moreover, though the immunoregulation agent for external use, the action mechanism of which is quite different from the steroid for external application, is highly effective especially for exanthemata in the face and the cervical region, it has peculiar skin stimulation and is a taboo for using especially in epidermolysis surface seen in atopic dermatitis and the like, and an advanced specialty and attention are demanded when using it. These medicines to the atopic dermatitis are symptomatic treatment medicines which aim at moderate solution of the symptom, and not those which aim at the treatment going back even the cause (Non-patent literature 2).

On the other hand, itching is understood as a sense which causes the impulse of wanting to scratch, and scratching off, a blow, and the like, which are accompanied by itching, are often the most complicating factors of atopic dermatitis. That is, if pruritus can be controlled, not only itching, which is the most suffering of the patient, can be softened to improve QOL (Quality of life), but also an indirect effect that an exanthema is improved by controlling scratching off can be expected. For these reasons, the development of a safe anti-pruritus agent that enables the loss in quantity or cessation of the symptomatic treatment medicine and is strong and can endure the chronic administration is waited for.

As one mode of such a medicine, a medicine for external application that acts only on the applied region and can avoid the systemic action by the internal use is cited. That is, compared with oral agents that the medicines are absorbed from an alimentary canal, an endermic liniment for external application becomes possible to absorb the medicine directly from the disorder affected part by the noninvasive zero-order discharge, to avoid the first-pass effect in the liver, to avoid dosage dependent systemic side effects, and to control medicinal concentration in the disorder affected part for long periods of time, and the merit of the medicine is considered that it can be used safely for cutaneous diseases often seen especially in elderly people, sick people, and infants. In fact, though the steroid drug has a strong anti-inflammatory activity and an anti-pruritic activity that accompanies it, it is not used as an oral medicine except for the remission of extremely severe symptoms. On the one hand, it is well known that the skin has a remarkably strong barrier function for a lot of medicines, so that effective medicines in oral administration are not necessarily effective even in dermal administration.

The present inventors have eagerly made progress in their studies, resulting in finding that the application of a 3-carbamoyl-2-pyridone derivative shown in the following on the skin of the disorder affected part makes the derivative act directly to the cannabinoid receptor existing in the periphery to reveal excellent anti-pruritic activity.

Though pyridone derivatives similar to the said compounds of the present invention are commercially available from Interbioscreen Corp., Interchim Corp., Asinex Corp., and Ambinter Sarl Corp. as reagents, pharmacological activity on these compounds has not described.

EFFECT OF INVENTION

In general, the compounds of the present invention have strong activity for both of the CB1 and CB2 receptors or either of them. In general, the strength of the activity can be indicated by the bonding activity (Ki value) to the receptor, the smaller the Ki value, the stronger the activity is (in vitro activity). Though the compounds of the present invention generally have the very wide range of bonding activity in the order of 0.1 nM to 5000 nM to both or either of the receptors, and the degrees of the selectivity to the both receptors (the ratio of Ki values to the CB1 and CB2 receptors) are also various, when applying the compound on the skin, the effect of restraining itching can be expected (in vivo activity) if the Ki value is about 50 nM or less. Consequently, a compound having a Ki value of 50 nM or less can be considered to be a preferable compound. As for the actual anti-pruritic activity of the compound of the present invention, when the compound to be inspected is dissolved in a solvent and applied on the skin with a compound 40/80 which causes itching, the effect can be confirmed by the density needed torestrain itching by 50% or more compared with the control group. It can be thought that the compound is the most preferable compound If itching can be restrained 50% or more significantly in the density of the active ingredient 3% or less.

Moreover, itching can be restrained also by the oral administration.

The compounds of the present invention have such features as low inhibition activity for enzyme (CYP), low central nerve side effects, excellent photostability, and the like.

The compounds of the present invention can be synthesized through compounds (V) with a carboxyl group in the third position as key intermediates. These key intermediates are synthesized by either of the methods shown in the route 1 to 3, and R¹, R², R³, and R⁴are introduced in the process of the method. Though R¹to R⁴become directly partial structures in the compound of the present invention, it is also possible that chemically transformable functional groups are incorporated beforehand and they are properly transformed into necessary functional groups for the compound of the present invention. This example will be described later.

wherein R¹, R², R³, and R⁴are as defined above.

Route 1: This method is suitable for synthesis of a compound in which R²is an alkyl, and R³is an alkyl or an alkoxy. Ketone (I) and formate (R⁴═H) are dissolved in a solvent such as ether or the like and stirred together with a sodium methoxide methanol solution at temperatures from ice temperature to room temperature for 12 to 24 hours, then B-diketone can be obtained as sodium salt (II). When the compound (II) is suspended in DMF without being purified and refluxed together with acetic acid being excessive a little, the catalytic amount of piperidine and cyanoacetamide derivative (III) for from several to 24 hours, 3-cyanopyridone derivative (IV) is obtained. At this time, if a suitable functional group is previously introduced in R¹, it can be transformed into various kinds of functional groups in the later phase. When an isomer is formed, both or only the necessary isomer may be taken out by the silica gel chromatography or the recrystallization at the phase of compound (IV). When the nitrile group of IV is refluxed for several to 24 hours in the water containing alcohol together with sodium hydroxide or potassium hydroxide in 1 to several equivalent weights, the aimed 3-carboxylic acid (V) is obtained. The end point of the reaction is decided by the vanishment of the raw material with TLC or HPLC. V can generally be made to be a key intermediate with sufficient purity by the recrystallization.

wherein R¹and R⁴are as defined above; R²and R³taken together with the adjacent carbon atoms form a 5 to 10 membered cycloalkene which may contain one group selected from —O—, —S—, —SO—, and —SO₂— in the ring.

Route 2: This method is particularly suitable for synthesis of a compound in which R²and R³are bonded in cyclic. That is, when a cyclic ketone body (VI) is warmed together with primary amine (VII) in a high boiling point solvent such as toluene, diglyme, or triglyme for 3 to 24 hours at the reflux temperature of the solvent while being dehydrated with the use of a dehydrator of Dean Stark, animine (VIII) is obtained. When the boiling point of the compound (VII) is low, it is also possible that the compound (VI) and the compound (VII) are stirred at room temperature with the catalytic amount of an acid catalyst such as concentrated hydrochloric acid or concentrated sulfuric acid to be transformed into the corresponding compound (VIII). Moreover, even if the methylene group in the compound (VI) is replaced with an oxygen atom or a sulfur atom, the reaction progresses similarly. In addition, when a suitable functional group is introduced into R¹beforehand, the group can be transformed into any one of various functional groups at an arbitrary phase. Methoxymethylene dimethyl malonate is added to the compound (VIII) and refluxed for 1 to 10 hours, a 3-methyl ester body (IX) in which R⁴is hydrogen is obtained. When trimethyl methanetricarboxylate is used instead of the malonic ester, 3-methyl ester (X) in which R⁴is the hydroxy group is obtained. In this case, the use of a high bp: solvent such as triglyme is preferable. Though it is preferable to refine the compound (IX) and the compound (X) by the silica gel chromatography or the recrystallization, generally, they are not refined, and the aimed key intermediate (V) can be induced by immediately adding the necessary amount of a water containing alcohol solvent such as methanol or ethanol, or a solvent of THF or the like when the compounds being insoluble in alcohol, and stirring with the slightly excessive amount or several equivalent weight of lithium hydroxide, sodium hydroxide, potassium hydroxide, or the like for 0.5 to several hours. The compound (V) synthesized by this method can generally be made to be a key intermediate with enough purity by the recrystallization.

wherein R¹, R², and R³are as defined above; R is a C1-C6 alkyl.

Route 3: When ketone (I or VI) and dimethylformamide dialkyl acetal are warmed at 100° C. to the reflux temperature of the solvent for 12 to 24 hours, ketoimine (XI) is obtained. As dimethylformamide dialkyl acetal, dimethylformamide dimethyl acetal, which is a commercial item easily obtainable, is generally used. When the compound (XI) is nor refined and is stirred with cyano acetic ester in a solvent such as methanol at room temperature, an ester body (XII) is precipitated as a hardly soluble solid. Compound (XII) is dissolved in DMF, THF, DMSO, or these compounds and is stirred with the slightly excessive amount of sodium hydride at room temperature to 60° C. for 0.5 to several hours. After that, when an alkylating agent (R¹—X) is added and stirred at room temperature to 50° C. for one to several hours, the compound (XIII) and compound (XIV) which are substituted for the first place or the second place are generally formed at the rate of 1:1. At this time, a suitable functional group can be introduced into R¹beforehand. As X of an alkylating agent, chlorine, bromine, iodine, the toluenesulfonyloxy group, the methanesulfonyloxy group, and the like are preferable. The compound (XIV) can be easily removed by the silics gel chromatography or the recrystallization. Then, the compound (XIII) is hydrolyzed by the above-mentioned method, leading to a key intermediate (V).

The compound (V), which can be synthesized by the above-mentioned method, is a key intermediate which can be used as a raw material for synthesizing all of the compounds of the present invention, and the manufacturing method will be described more in detail by the referential examples. However, the manufacturing method of the compound (V) is not limited only to these three routes.

Next, as an example in which a suitable functional group is incorporated beforehand and transformed to the desired functional group at a suitable phase, the method of introducing the amino group into the end of R¹will be described.

wherein R¹, R², R³, and R⁴are as defined above; A′ is a C1-C8 alkylene group optionally substituted with one to two substituents selected from the above-mentioned substituent group A.

The 3-ester (XVII) is obtained from a compound (I) or a compound (VI) and a compound (XV) by the method of route 1 or 2. The hydroxy group can be transformed to various functional groups. For example, when compound (XVII) is reacted in a solvent such as THF or methylene chloride with the chlorinated toluene sulfonate and chlorinated methane sulfonate in the presence of a tertiary base such as pyridine or triethyl amine at temperatures from ice temperature to room temperature, a tosylate body or a mesylate body which corresponds respectively is obtained. These substituents can easily receive the nucleophilic substitution reaction as a leaving group to be transformed into other functional groups. For example, when these substituents are reacted with sodium azide in a solvent such as DMF or DMSO at temperatures of 100° C. to the reflux temperature of the solvent, they can be transformed into azide (XVIII). The azide is easily reduced with catalytic reduction, or by triphenylphosphine and the like to form an amino (XIX). The compound (XIX) is further not only transformed easily into various functional groups such as secondary amine, tertiary amine, an amide, a sulfonamide, and a carbamate, which are widely used as partial structures in pharmaceuticals, but made to be new intermediates by introducing proper protecting groups. Though it does not needed to explain the methods of concretely transforming these functional groups for those skilled in the art, concrete methods have been given in, for example, Harrison, I., Harrison, S., Compendium of Organic Synthesis Vol I-II, Wiley-Interscience, NY (1971, 1977), Hegedus, L. S., Wade, L., Compendium of Organic Synthesis Vol III, John Wiley & Sons, NY (1977), Sandler, S. R., Karo, W., Organic Functional Group Preparations, 2nd Ed., Academic Press, NY (1983), Experimental chemistry course, 4th Ed., Organic synthesis I-V, Maruzen (1992), and others. Carboxylic acids (V), in which R1 is modified, can be obtained by hydrolyzing various compounds (XX) manufactured in such ways. As for other functional groups, the above-mentioned methods have only to be followed basically.

Next, the methods of transforming key intermediates (V) into 3-carbamoyl (XXII to XXV), which are features for the compounds of the present invention, will be described. It does not needed to explain the methods of transforming carboxylic acids into acid amide bodies for those skilled in the art. Concretely, though it is sufficient only to follow the methods described in the following documents, for example, Harrison, I., Harrison, S., Compendium of Organic Synthesis Vol I-II, Wiley-Interscience, NY (1971, 1977), Hegedus, L. S., Wade, L., Compendium of Organic Synthesis Vol III, John Wiley & Sons, NY (1977), Sandler, S. R., Karo, W., Organic Functional Group Preparations, 2nd Ed., Academic Press, NY (1983), Experimental chemistry course, 4th Ed., Organic synthesis I-V, Maruzen (1992), and others, acid amide bodies can be usually manufactured acid by the following methods.

wherein R¹, R², R³, R⁴, R⁵, X¹, X², X³, Y, Z, G, G¹, and G²are as defined above.

Carboxylic acid (V) is reacted with oxalyl chloride in a solvent such as dichloromethane or THF in the presence of the catalytic amount of DMF at room temperature and transformed into the acid chloride. Instead of using oxalyl chloride, carboxylic acid (V) can also be transformed into the acid chloride by refluxing it with thionyl chloride in a nonpolar solvent such as benzene or methylene chloride, or without using a solvent. When the acid chloride is not refined and reacted with an amine body (XXI) in a solvent such as methylene chloride or THF in the presence of a base such as triethyl amine or pyridine at temperatures from cooling with ice to room temperature for one to six hours, amide (XXII) is obtained. When the amino group of the compound (XXI) is a salt such as an inorganic acid, tertiary amine only has to be added simultaneously in the reaction mixture in the enough amount of neutralizing the salt. The compound (XXII) can also be manufactured directly from the compound (XXI) and the compound (V) in the presence of an activator such as, for example, WSCD-HOBt. When the progress of the reaction is late, the irradiation of the microwave is effective, and even such a reaction as does not progress under a usual condition ends within tens of minutes. The separation of a product difficult to be isolated can also be facilitated with the use of a reagent fixed to a polymer carrier.

Compounds (XXI) can be classified into compounds (XXIII), compounds (XXIV), and compounds (XV) according to the kinds of G. Furthermore, the part of —Y-Z can be transformed into various functional groups with the use of the definite method if necessary. For example, when —Y-Z is alkoxy in a compound (XXIII) or a compound (XXIV), after the alkoxy is transformed into acid halide with the use of a carboxylic acid XXVI obtained by the hydrolysis, the acid halide can be reacted with alcohols, mercaptans or amines to form compounds (XXIII) in which Y becomes an oxygen atom, a sulfur atom, and a nitrogen atom, respectively. In this case, the amidation method previously described can be applied.

wherein R¹, R², R³, R⁴, R⁵, X¹, X², X³, Y, and Z are as defined above.

When the asymmetric center exists in the alpha place in the carbonyl and the racemization progresses in the process of the hydrolysis, a protecting group such as, for example, the benzhydryl group or the tertiary butyl group, which can receive easily the acid hydrolysis at room temperature, is introduced as Z and the hydrolysis may be carried out in a mild acid condition. The compounds of the present invention have a wide variety of structures, and the compounds (XXIII) are not only compounds of the present invention but also very useful as intermediates for manufacturing more complex derivatives and will be described in detail in examples.

Examples of manufacturing various compounds of the present invention using carboxylic acids (XXVI) include, for example, manufacturing amide bodies (XXVIII) by the reactions with compounds (XXVII) which have the amino group. In this time, for example, if a protected amino group exists in the terminal, after canceling the protection, another substituent can be newly introduced and the amino group can also be transformed easily into various functional groups widely used as partial structures in pharmaceuticals such as an amid body, a sulfonamide body, and a carbamate body.

In the present invention, not only a compound of the present invention, which has the cannabinoid receptor agonist action, but also the salt allowed in medicine manufacture or a solvate thereof can be used.

Testing Example 5
Test with a Rat OVA Asthma Model

Egg albumin (OVA) of 0.1 mg/mL and aluminum hydroxide gel of 1 mg were administered in the abdominal cavity of Brown Norway (BN) rat, and the rat was sensitized to them. On 12, 19, 26, and 33 days after the sensitization, 1% OVA solution was made an aerosol with ultrasonic nebulizer (NE-U17), the rat which had put in the chamber for the exposure was subjected to the inhalation exposure of this aerosol for 30 minutes. A compound of the present invention was orally administered by 10 mg/kg once a day continuously for three days since one hour before an antigen exposure of the fourth times. To the control group, 0.5% methyl cellulose was administered instead of a compound of the present invention.

On the three days after the antigen exposure of the fourth times, under the pentobarbital anesthesia (80 mg/kg, i.p.), acetylcholine (3.9, 7.8, 15.6, 31.3, 62.5, 125, 250 and 500 μg/kg) was injected in the cervix region vein of the rat with one by one in five minutes from a low dosage, and the airway shrinkage reaction (increase in insufflation pressure) caused immediately after the injection was measured by Konnzett & Rossler method partly modified. The depressant rate of airway hyperreactivity exacerbation to the control group was calculated from the area under the curve (AUC) calculated from the concentration reaction curve of the acetylcholine.

After the measurement of the airway hyperreactivity had ended, the bronchus alveoli of the rat were washed three times with the physiological saline of 5 mL, the total cell count in the cleaning solution was counted by using the hemacytometer under an optical microscope, and the depressant rate of the inflammatory cellular infiltration to the control group was calculated. In addition, the mucin in the airway cleaning solution is measured by the ELISA method using jacalin which is mucin binding lectin, and the depressant rate of the mucus secretion to the control group was calculated.

Testing Example 6
Test with a Guinea Pig Nasal Congestion Model

One percent egg albumin (OVA) solution was made an aerosol, and this aerosol was made to be inhaled in a Hartley male guinea pig for ten minutes for each twice every week and the guinea pig was sensitized to it. On the seven days later, the antigen was exposed and the reaction was caused. Under the pentobarbital anesthesia (30 mg/kg, i.p.), the guinea pig's trachea was incised and cannulas were installed in the nasal cavity side and the lung side respectively, and on the lung side, an artificial respirator, which supplies with air 60 times per minute and 4 mL each time, was connected. After guinea pig's spontaneous respiration had been stopped with galamine (2 mg/kg, i.v.), the air of 70 times per minute and 4 mL once was sent to the nasal rostrum from the cannula on the nasal cavity side with the artificial respirator, and air pressure necessary for the air supplying was measured by transducer which installed in the side branch and the pressure was assumed the index of the nasal resistance. The antigen was exposed by generating the aerosol of 3% OVA solution for three minutes between the artificial respirator and the nasal cavity cannula. A compound of the present invention was injected in the vein ten minutes before the antigen exposure. As for the result, the nasal resistance was continuously measured during 30 minutes from 0, and the depressant rate to the vehicle was obtained based on the index of the AUC (nasal resistance (cm H₂O) in the vertical axis and time (0 to 30 minutes) in the horizontal axis) of the 30 minutes.
