Benzenesulfonamide derivatives

TECHNICAL FIELD
The present invention relates to a benzenesulfonamide derivative or a pharmacologically acceptable salt thereof exhibiting excellent activity as a drug.
BACKGROUND ART
Phospholipase A is an enzyme catalyzing the hydrolysis of the acyl linkage of glycerophospholipid and includes phospholipase A catalyzing the hydrolysis of 1-ester linkage of glycerophospholipid and phospholipase A.sub.2 catalyzing that of 2-ester linkage thereof. Although both of the phospholipases are widely distributed in the biological world, they have recently been noted from the standpoint of their connection to various diseases.
For example, in ischemic diseases such as cardiac infarction, it is believed that phospholipase is activated to disintegrate membrane phospholipid, giving an increased infarct size. Furthermore, studies have been made on the connection of the phospholipase to other various troubles.
Under these circumstances, various phospholipase A.sub.2 inhibitors have been proposed from the standpoint that the inhibition of phospholipase, particularly phospholipase A.sub.2 (PLA.sub.2) is effective in the prevention and treatment of various diseases (see Japanese Patent Laid-Open Nos. 255,749/1985, 175,466/1987, 2,968/1988 and 258,854/1988).
The inventors of the present invention have eagerly studied for many years on substances which can inhibit phospholipase A.sub.2 to find out that a benzenesulfonamide derivative or a pharmacologically acceptable salt thereof which will be described below exhibits a high inhibitory activity against phospholipase A.sub.2 and therefore is useful in the prevention and treatment of various diseases, for example, ischemic diseases such as cardiac infarction. The present invention has been accomplished on the basis of this finding.

Step 1
In this step, a ketone or aldehyde (II) which is known in itself or can be prepared by a known process is converted into a cinnamic acid derivative (III) through Wittig reaction, aldol condensation or Knoevenagel reaction. When the conversion is conducted through Wittig reaction, a compound (II) is reacted with a Wittig reagent such as triethylphosphonoacetate, triethylphosphonocrotonate or triethylphosphonopropionate generally in an inert solvent such as dimethylformamide, ether, tetrahydrofuran, dioxane, benzene, toluene or dimethyl sulfoxide in the presence of a base such as potassium butoxide, potassium hydroxide, sodium hydroxide, sodium methoxide, sodium ethoxide, sodium hydride or n-butyllithium at a temperature of -78.degree. to 150.degree. C. according to a conventional process to give a compound (III).
The compound (III) can be prepared also through aldol condensation or Knoevenagel reaction according to a conventional process.
Step 2
In this step, the compound (III) prepared in Step 1 is converted into a carboxylic acid derivative (IV) through the hydrolysis of an ester linkage. For example, the hydrolysis is conducted in a dilute aqueous solution of an alkali or a mineral acid, preferably a mixture comprising a 0.5 to 3N aqueous solution of sodium hydroxide and ethanol at a ratio of 1:1 or in a 2 to 6N aqueous solution of hydrochloric acid at room temperature to refluxing temperature.
Step 3
In this step, the compound (IV) prepared in Step 2 is halogenated into an acid halide derivative (V). The halogenation is conducted by reacting the compound (IV) with oxalyl chloride, thionyl chloride, phosphorus trichloride or phosphorus tribromide in an inert solvent such as dichloromethane, chloroform, dichloroethane, benzene or toluene at room temperature to refluxing temperature according to a conventional process. When oxalyl chloride is used, it is preferable to use dimethylformamide as a catalyst.
In some cases, the compound (IV) may be converted into other reactive derivative, for example, acid azide, active ester with N-hydroxybenzotriazole or N-hydroxysuccinimide, symmetric acid anhydride or mixed acid anhydride with alkylcarbonic or p-toluenesulfonic acid. These reactive derivatives may be also used in Step 7.
Step 4
In this step, an acetanilide derivative (VI) which is known in itself or can been prepared by a known process is sulfochlorinated into a compound (VII). For example, the compound (VI) is reacted with excess chlorosulfonic acid in an inert solvent such as chloroform, dichloroethane, trichloroethane or nitrobenzene or in the absence of any solvent at room temperature to 100.degree. C. to give a compound (VII).
Step 5
In this step, the sulfonyl chloride derivative (VII) prepared in Step 4 is reacted with an amine (VIII) which is known in itself or can be prepared by a known process to prepare a sulfonamide derivative (IX). For example, the objective compound (IX) can be prepared by reacting the derivative (VII) with an amine (VIII) in a solvent such as water, methanol, ethanol, propanol, acetonitrile, tetrahydrofuran, dioxane, dimethylformamide, dimethyl sulfoxide, dichloromethane, chloroform, benzene or toluene in the presence of a base such as sodium acetate, sodium hydrogencarbonate, sodium carbonate, triethylamine or pyridine at a temperature of 0.degree. C. to room temperature.
Step 6
In this step, the sulfonamide derivative (IX) prepared in Step 5 is converted into an aniline derivative (X) through the hydrolysis of the N-acyl group. The hydrolysis is conducted in a dilute aqueous solution of an alkali or a mineral acid. Preferably, it is conducted in a 2 to 6N aqueous solution of hydrochloric acid or a 0.5 Lo 3N aqueous solution of sodium hydroxide at 50.degree. C. to refluxing temperature.
Step 7
In this step, an amide derivative (XI) is prepared by the reaction of the acid halide or other reactive derivative (V) prepared in Step 3 with the aniline derivative (X) prepared in Step 6.
In the above reaction, the compounds (V) and (X) are used in equimolar amounts or either of them is used in slight excess. The reaction is conducted in an inorganic solvent inert to the reaction, for example pyridine, tetrahydrofuran, dioxane, ether, benzene, toluene, xylene, dichloromethane or chloroform. In some cases, the addition of a base such as diisopropylamine, triethylamine, pyridine, picoline, lutidine, N,N-dimethylaniline, 4-dimethyaminopyridine, potassium carbonate or sodium hydroxide is effective in making the reaction proceed smoothly. Although the reaction temperature varies depending upon the kind of the reactive derivative and therefore is not particularly limited, the reaction is generally conducted at a temperature of 20.degree. C. to refluxing temperature to give an objective compound (XI).
Step 8
Among the compounds (XI) prepared in Step 7, a compound (XII) having an acetoxy group as R.sup.1 is converted into a phenol derivative (XIII) in this step through the hydrolysis of the acetyl group.
The hydrolysis is conducted according to a conventional process, for example, either in a solvent such as water, methanol, ethanol, propanol, acetonitrile, tetrahydrofuran or dioxane in the presence of a base such as lithium hydroxide, sodium hydroxide, potassium hydroxide, sodium carbonate, potassium carbonate or sodium hydrogencarbonate, or in a 0.5 to 6N solution of a mineral acid, at a temperature of 0.degree. C. to refluxing temperature.
Step 9
Among the compounds (XI) prepared in Step 7, a compound (XII) having an alkoxy group such as a methoxy group as R.sup.1 is converted into a phenol derivative (XIII) through the dealkylation of the alkoxy group in this step.
The dealkylation is conducted according to a conventional process, for example, in an inert solvent such as dichloromethane, chloroform, dichloroethane or nitrobenzene in the presence of a dealkylating agent, for example, boron halide such as boron tribromide, boron trichloride or boron triiodide or aluminum halide such as aluminum trichloride or aluminum tribromide at 0.degree. C. to refluxing temperature.
Step 10
In this step, the phenol derivative (XIII) prepared in Step 8 or 9 is acylated into a compound (XIV). The acylation is preferably conducted by reacting the phenol derivative (XIII) with an amino acid such as glycine, alanine or valine or a carboxylic acid such as nicotinic acid in an inert solvent such as acetonitrile, tetrahydrofuran, dioxane, ether, benzene, toluene, dichloromethane, chloroform, dimethylformamide or dimethyl sulfoxide in the presence of a condensing agent such as dicyclohexylcarbodiimide, 1,1,-carbonyldiimidazole, ethyl chloroformate, diethyl azodicarboxylate or dipyridyl disulfide at a temperature of 0.degree. C. to refluxing temperature.
Step 11
In this step, a sulfonamide derivative (XVI) is prepared by reacting the sulfonyl chloride derivative (VII) prepared in Step 4 with an amine derivative (XV) wherein R.sup.12 is a nitrogen-protective group such as a benzyl, methoxybenzyl, t-butoxycarbonyl or benzyloxycarbonyl group which is known in itself or can be prepared by a known process. This reaction may be conducted in a similar manner to that described in Step 5.
Step 12
In this step, the compound (XVI) prepared in Step 11 is freed from the N-protective group to give an amine derivative (XVII).
When R.sup.12 is a benzyl, methoxybenzyl or benzyloxycarbonyl group, it can be removed according to a conventional process. For example, it can be removed by hydrogenating the compound (XVI) in a solvent such as water, methanol, ethanol, propanol, acetonitrile, dioxane, tetrahydrofuran, ether, ethyl acetate or dimethylformamide in the presence of a catalyst such as palladium/carbon, palladium black, platinum oxide or Raney nickel at room temperature to refluxing temperature. In some cases, the coexistence of an acid such as acetic or hydrochloric acid is preferable. When R.sup.12 is a t butoxycarbonyl group, it can be removed by treating the compound (XVI) in a 1 to 3N solution of hydrochloric acid in a solvent such as water, methanol or ethanol at a temperature of 0.degree. C. to room temperature or by reacting the compound (XVI) with a fluoride reagent such as KF or tetraalkyl ammonium fluoride in a solvent such as methanol, ethanol, acetonitrile, tetrahydrofuran, dioxane or dichloromethane at a temperature of 0.degree. C. to room temperature, though it can be removed also by a conventional process as described above.
Step 13
In this step, the amine derivative (XVII) prepared in Step 12 is converted into a compound (XX) through N-alkylation. The alkylation is conducted by a conventional process. For example, when the alkylating agent is a compound (XVIII), the compound (XX) can be prepared by reacting the compound (XVII) with the compound (XVIII) in a solvent, for example, dimethylformamide, dimethyl sulfoxide, a lower alkyl alcohol such as methanol, ethanol or propanol, acetone, benzene, chloroform or dichloromethane in the presence of a base at room temperature to refluxing temperature. The base includes potassium carbonate, sodium carbonate, sodium hydrogencarbonate, sodium methoxide, sodium ethoxide and sodium hydride. In some cases, the additional use of lithium bromide or potassium iodide gives better results.
When the alkylating agent is a compound (XIX), the objective compound (XX) can be prepared by reacting the compound (XIX) with the amine derivative (XVII) in a polar solvent such as water, methanol, ethanol, dioxane tetrahydrofuran or acetonitrile or a mixture thereof with water in the presence of a small amount of hydrochloric acid, acetic acid or sodium acetate at a temperature of 50.degree. C. to refluxing temperature.
When B is a substituted or unsubstituted pyridyl alkyl group, the compound (XX) can be prepared by the condensation of the compound (XVII) with an alkylating agent represented by the formula (XVIII): B-Z. Particularly, when B is a substituted or unsubstituted pyridylethyl group (i.e., when the alkyl group in the above definition is an ethyl group), the compound (XX) can be prepared also by the addition reaction of the compound (XVII) with a compound represented by the formula (XIX) E--CH.dbd.CH.sub.2.
When E is a pyridyl group which is unsubstituted or substituted with a lower alkyl group, the formula (XIX) can be replaced by the following formula: ##STR34##
Step 14
In this step, the compound (XX) prepared in Step 13 is converted into an aniline derivative (XXI) through the hydrolysis of the N acyl group. The hydrolysis can be conducted in a similar manner to that of Step 6.
Step 15
In this step, an amide derivative (XXII) is prepared by reacting the aniline derivative (XXI) prepared in Step 14 with the acid halide or other reactive derivative (V) prepared in Step 3. This reaction can be conducted in a similar manner to that of Step 7.

Pharmacological Experiment Examples with respect to representative compounds according to the present invention will now be described in order to illustrate the effects of the present invention in more detail.

PHARMACOLOGICAL EXPERIMENT EXAMPLES
A. Inhibitory activity against phospholipase A.sub.2 (PLA.sub.2) contained in the membrane fraction of rabbit heart or the supernatant fraction thereof (method)
1. Preparation of membrane fraction of rabbit heart and supernatant fraction thereof
An NZW male rabbit was anesthetized by the intravenous administration of pentobarbital sodium to take out its heart. This heart was washed with ice cooled physiological saline to recover a ventricle, followed by the addition of ice-cooled 0.25M sucrose/20 mM tris hydrochloride buffer (pH: 8.0) in an amount of 5 ml per g of the ventricle. The obtained mixture was mashed with a homogenizer in ice water for 30 minutes and centrifuged at 1,000 g for 10 min. The supernatant was further centrifuged at 105,000 g for 60 min. The centrifugation was conducted at 0.degree. to 4.degree. C. The obtained supernatant was used as such as the supernatant fraction for examination. The precipitate was suspended in the same buffer as that described above and used as the membrane fraction for examination. The protein concentrations of these fractions were each adjusted to 5 mg/ml as determined by Lowry method.
2. Determination of PLA.sub.2 -inhibitory activity
A 100 mM CaCl.sub.2 solution was added to the above membrane fraction in an amount of 100 .mu.l per 10 ml of the fraction, while a 100 mM solution of ethylene glycol bis(.beta.-aminoethyl ether)-N,N,N',N'-tetraacetic acid (EGTA) was added to the above supernatant fraction in an amount of 500 .mu.l per 10 ml of the fraction. The obtained mixtures were each poured into test tubes in an amount of 0.2 ml per tube, followed by the addition of 2 .mu.l of a solution of a test compound in dimethyl sulfoxide (DMSO) into each of the tubes, while 2 .mu.l of DMSO was poured into a test tube for control. 5 .mu.l of an 8 mM ethanol solution of phosphatidylcholine (1-palmitoyl-2-[1-.sup.14 C]arachidonyl, 1.184 MBq/ml) was added to each of the test tubes. The test tubes of the membrane fraction were kept at 37.degree. C. for 30 minutes for incubation, while those of the supernatant fraction were kept at 37.degree. C. for 5 minutes for incubation. Each incubation was stopped by the addition of 1 ml of Dole reagent. The .sup.14 C-arachidonic acid was extracted with heptane and the heptane layer was passed through silica gel to remove the phosphatidylcholine contained therein by adsorption. The amount of .sup.14 C was determined with a liquid scintillation counter.
Mepacrine was selected as a comparative compound. (Results)
The results are given in Table 1.

B. Influence on the cardiac infarct size of rat
Sixty-one male rats (weight : 220 to 300 g) were made to get myocardial ischemia by the ligation of the coronary artery. After 3 hours from the ligation, hearts were taken out of the rats and cut into round slices to obtain preparations. These preparations were stained with myoglobin. The area unstained therewith was regarded as a cardiac infarction nidus and the area ratio of the nidus to the left ventricle was determined by the image analysis and regarded as the cardiac infarct size.
The cardiac infarct size was reduced as compared with that of the control rat by 21% or 20% by the administration of the compound of Example 4 or 6 through the tail vein in a dose of 1 mg/kg before 15 minutes prior to the ligation of the coronary artery.
C. Toxicity test
A small amount of 1N HCl was added to each of the compounds of Examples 4, 6, 7, 8 and 15 to form aqueous solutions. These solutions were each intravenously administered to the groups of three male SD rats of 7 weeks of age in a dose of 50 mg/kg. All of the groups of rats were observed for 3 hours after the administration. No rat died.
It can be understood from the results of the above Pharmacological Experiment Examples that each of the compounds of the present invention has a remarkably high inhibitory activity against phospholipase A.sub.2 to arrest the course of a series of ischemic cell diseases which are thought to be caused by the activation of phospholipase A.sub.2, for example, cardiac infarction.
