(Fused) Benz (Thio) Amides and Pharmaceutical Compositions, Thereof

This invention is related to novel (fused) benz(thio)amides.

More particularly, this invention is related to novel (fused) benz(thio)amides having an antagonistic activity on leukotrienes (SRS) and an inhibitory activity on 5.alpha.-Reductase; processes for the preparation of them; and pharmaceutical agent containing them as active ingredient.

In the study of prostaglandins (abbreviated as PG hereafter), many important discoveries have been made continuously in recent years. And so it was found a large change in the direction of the research and development of PG. In the compounds which have been newly found or newly confirmed their structure in PG family, it can be said that PG endoperoxides, (i.e. PGG.sub.2 and PGH.sub.2), thromboxane A.sub.2 (abbreviated as TXA.sub.2 hereafter), prostacyclin (i.e. PGI.sub.2) and leukotriene C.sub.4, D.sub.4 and E.sub.4 (abbreviated as LTC.sub.4, LTD.sub.4 and LTE.sub.4, respectively, hereafter) etc. have especially strong and unique biological activities.

All the compounds of PG family containing various PG previously known well in addition to the above compounds, are biosynthesized from the same mother compound, i.e. arachidonic acid in a living body and, therefore, the metabolic routes starting from arachidonic acid is called "Arachidonate cascade" as a whole. The detailed explanation of each route and the pharmacological character of each metabolite are described in Igaku No Ayumi, 114, 378 (1980), ibid, 114, 462 (1980), ibid, 114, 866 (1980), ibid, 114, 929 (1980), Gendai Iryo, 12, 909 (1980), ibid, 12, 1029 (1980), ibid, 12, 1065 (1980) and ibid, 12, 1105 (1980) etc.

The arachidonate cascade can be largely divided into two routes; one is the route that cyclooxygenase acts on arachidonic acid to convert, into various PGs, e.g. prostaglandin F.sub.2 (abbreviated PGF.sub.2 hereafter) prostaglandin E.sub.2 (abbreviated PGE.sub.2 hereafter), PGI.sub.2, TXA.sub.2, via PGG.sub.2 and further PGH.sub.2 and the other is the route that lipoxygenase acts on arachidonic acid to convert, in hydroxyeicosatetraenoic acid (abbreviated as HETE hereafter) or leukotrienes, via hydroperoxyeicosatetraenoic acid (abbreviated HPETE hereafter).

As the former route is well known, it is not described in the present specification in detial. See Prostaglandin (1978), edited by Makoto Katori et al., published by Kohdan-sha.

Concerning the latter route, it has been known that various compounds are produced according to the following scheme I. ##STR7##

Besides being metabolized through a well known route, i.e. the route via PG endoperoxides, arachidonic acid is also metabolized through another route by the action of lipoxygenase. That is to say, arachidonic acid is metabolized by the action of lipoxygenase, e.g. 5-lipoxygenase, 12-lipoxygenase and 15-lipoxygenase, to 5-HPETE, 12-HPETE and 15-HPETE, respectively.

These HPETE are converted into 5-HETE, 12-HETE and 15-HETE, respectively, by the action of peroxidase converting a hydroperoxy group into a hydroxy group. Furthermore, LTA.sub.4 is also produced from 5-HPETE by dehydration. LTA.sub.4 is converted into leukotriene B.sub.4 (abbreviated as LTB.sub.4 hereafter) or LTC.sub.4 enzymatically. Further, LTC.sub.4 is converted into LTD.sub.4 by the action of .gamma.-glutamyl transpeptidase.

Moreover, it was recently defined that LTD.sub.4 is metabolized to LTE.sub.4 (see Biochem. Biophys. Res. Commun., 91, 1266 (1979) and Prostaglandins, 19 (5), 645 (1980)).

Besides, SRS is an abbreviation of Slow Reacting Substance and it was named by Feldberg et al. for the substance released when perfusing cobra venom through isolated lung or incubating cobra venom with vitellus. And it was reported that the substance constricted ilem isolated from guinea pig slowly and continually (see J. Physiol., 94, 187 (1938)).

Moreover, Kellaway et al. showed the relation between SRS-A and allergic reaction from the fact that SRS-A is released when an antigen is sensitized to perfusing lung isolated from guinea pig (see Quant. J. Exp. Physiol., 30, 121 (1940)).

Brocklehurst reported that when the antigen is sensitized to a lung fragment isolated from a bronchial asthmatics whose specific antigen is defined, by an operation, histamine and SRS-A are released and strongly constrict bronchial muscle. Since such constriction can not be prevented by an antihistaminic agent, he suggested that SRS-A is an important bronchoconstrictor in an asthmatic paroxysm (see Progr. Allergy, 6, 539 (1962)).

Since then, many reports were published, for instance, SRS-A prepared from human lung slice constrict a tracheal spiral of normal human (see Int. Arch. Allergy Appl. Immunol., 38, 217 (1970)); when SRS-A prepared from rats is injected intravenously to guniea pig, significant increase of pulmonary resistance is observed (see J. Clin. Invest., 53, 1679 (1974)); in addition, a subcutaneous injection of SRS-A to guinea pig, rat and monkey enhances vascular permeability (see Advances in Immunology, 10, 105 (1969), J. Allergy Clin. Immunol., 621, 371 (1978), Prostaglandins, 19 (5), 779 (1980) etc.).

Generally, the substance released by immunological reaction is called SRS-A. On the other hand, the substance released by non-immunological reaction such as calcium ionophore is called SRS. However, the above two substances have many similarities to each other and, therefore, it is considered they would probably be the same substance.

Further, it was confirmed that SRS or SRS-A is a mixture of LTC.sub.4 and LTD.sub.4. So it can be understood that the pharmacological characters of these leukotrienes are the same as those of SRS or SRS-A (see Proc. Natl. Acad. Sci. USA, 76, 4275 (1979), Biochem. Biophys. Res. Commun., 91, 1266 (1979), Proc. Natl. Acad. Sci. USA, 77, 2014 (1980) and Nature, 285, 104 (1980)).

Based on results of these studies, various leukotrienes (the structures of LTC.sub.4, LTD.sub.4 and LTE.sub.4, and further other leukotrienes which may be confirmed in the future) biosynthesized from arachidonic acid via LTA.sub.4, are considered to be important factors relating to the appearance of allergic tracheal and bronchial diseases, allergic lung diseases, allergic shock and various allergic inflammations.

To surpress leukotrienes is useful for the prevention and/or treatment of tracheal bronhcial or lung diseases such as asthma, allergic lung diseases, allergic shock or various allergic diseases.

On the other hand, arachidonic acid is released from phospholipids by the action of phospholipase, and two routes were generally accepted that (1) one is the route that phospholipase A.sub.2 is reacted on phosphatidyl choline, and (2) the other is the route that phospholipase C was reacted on phosphatidyl inositol to produce 1,2-diglyceride, and diglyceridelipase followed by monoglyceridelipase were reacted on it to release arachidonic acid (see Kagaku to Seibutsu (Chemistry and Biology), 21, 154 ( 1983)).

And it was known that arachidonic acid released is metabolized through two different routes i.e. (1) metabolizing route to bioactive substances e.g. prostaglandins (PGs), thromboxane A.sub.2 (TXA.sub.2) by cyclooxygenase, and (2) metabolizing route to bioactive substances e.g. SRS-A (Slow Reacting Substances of Anaphylaxis), hydroxyeicosatetraenoic acid (HETE) and leukotriene B.sub.4 (LTB.sub.4) by lipoxygenase (see Kagaku to Seibutsu (Chemistry and Biology), 21, 154 (1983)).

These metabolites are known as chemical mediators; for example, TXA.sub.2 is a compound which have a potent activity of platelet aggregation and aotra contraction, SRS-A is a chemical mediator on asthma, LTB.sub.4 is a chemical mediator on various inflammations (e.g. gout), and PGs are also chemical mediators on various inflammations which enhance a vascular permeability and a pain, and have a vasodilative action, pyrogenetic action and chemotactic action (see Prostaglandin (1978), edited by Makoto Katori et al, published by Kohdan-sha).

Arachidonic acid is converted and metabolized to various chemical mediators which act important physiological part in living body. And it was known that ill-balances of those chemical mediators induce various disorders.

And as antagonist of SRS, the groups of the compounds of general formula: ##STR8## (wherein from R.sup.1 to R.sup.5 and R.sup.7 each represent a hydrogen atom, a hydroxy group, an alkyl group of from 1 to 6 carbon atom(s), an alkoxy group of from 1 to 6 carbon atom(s), an amino group, an acyl group, an acylamino group of from 2 to 6 carbon atoms, an alkenyl group of from 2 to 6 carbon atoms, a halogen atom or a phenylalkoxy group in which alkoxy have from 1 to 6 carbon atom(s); X represents a hydrocarbyl group of from 1 to 10 carbon atom(s) being optionally substituted by hydroxy group(s); A represents an oxygen atom or is absent; Q represents an alkylene, alkenylene or alkynylene group of from 2 to 6 carbon atoms which may be branched; D represents a carboxy group, a 5-tetrazolyl group or carbamido-5-tetrazolyl group.) were described in the patent publication by Fiscons Co., (see Japanese Patent Application No. 55-1273841 i.e. European Patent Publication No. 17332 or U.S. Pat. No. 4281008.).

And, the following compounds were described in the patent publication by Kissei Pharmaceutical Co., Ltd, as anti-allergic agent, of the general formula: ##STR9## (wherein R.sup.1 and R.sup.2 each represent a hydrogen atom or an alkyl group with 1-4 carbon atoms; R.sup.3 and R.sup.4 each represent a hydrogen atom or may be combined together to form an additional chemical bond; X represents a hydroxyl group, a halogen atom, a straight or branched chain saturated or unsaturated alkyl group with 1-4 carbon atoms, a straight or branched chain saturated or unsaturated alkoxy group with 1-4 carbon atoms, an acyloxy group with 1-4 carbon atoms, or a cycloalkyl group with up to 6 carbon atoms; n is zero or an integer of 1-3 with the proviso that when n is 2 or 3; X's may be the same or different and that when two X's are commonly the alkyl or alkoxy group, both X's may be combined together to form a ring; and Y represents a straight or branched chain alkylene group or a straight or branched chain oxyalkylene group connected to the benzene nucleus through an oxygen atom.) as well as physiologically acceptable salts thereof. (see U.S. Pat. No. 4,026,896.)

And benzamides, i.e. compounds represented by the general formula (I) depicted hereafter, wherein the symbol B is opened and R.sup.4 is a group of the formula: --OCH.sub.2 COOR, were described in the prior patent application by the present inventors. (see Japanese Patent Application Kokai Nos. 60-97946, 60-116657, 60-142941 and 60-146855.)

The present inventors have synthesized novel compounds of the general formula (I) depicted hereafter, which have a structure characterized as a (thio)amido group substituted on a fused benzene ring or benzene ring and have found the compounds have potent antagonistic activity on leukotrienes (SRS), and then achieved the present invention.

And, the compounds of the present invention also inhibit phospholipase, so inhibit release of arachidonic acid from phospholipids, and therefore are useful for prevention and/or treatment of diseases induced by arachidonate metabolites e.g. TXA.sub.2, PGs, luekotrienes in mammals including human beings, especially human beings.

Examples of the diseases to the subject are various allergic diseases induced by luekotrienes described above, thrombosis e.g. one induced by injury (damage) of cerebral or coronary, endothelium or intima and inflammations e.g. arthritis, rheumatism (see Junkan Kagaku (Cardiovascular Science) 3, 484 (1983) Yakkyoku (Pharmacy) 34, 167 (1983)).

It was found that the compounds of the present invention also have an inhibitory activity on 5.alpha.-reductase described below, besides the activity of luekotriene antagonist and phospholipase inhibitor described above.

5.alpha.-Reductase presents in endoplasmic reticulum and nucleic acid, and it converts testosterone which is taken into a target tissue, into active 5.alpha.-dihydrotestosterone. The activated 5.alpha.-dihydrotestosterone induces cell proliferaction by binding to an intracelluar receptor. Activation of this enzyme is considered to cause some diseases such as prostatic hypertrophy, resulting in pattern baldness and acne.

As a matter of course, the compounds of the present invention have no activity peculiar like hormones, and inhibit 5.alpha.-reductase, so suppress increasing of 5.alpha.-dihydrotestosterone, therefore suppress cell proliferaction, and therefore are useful for the prevention and/or treatment of prostatic hypertrophy, male pattern baldness and acen in mammals including human beings especially human beings.

Furthermore, it was found that the compounds of the present invention also have an inhibitory activity on aldose reductases.

An aldose reductase is an enzyme which reduces an aldose (e.g. glucose, galactose) into the corresponding polyol (e.g. sorbitol, galactitol) in human beings or other animals. The sorbitol and galactitol produced by the action of this enzyme are accumulated in the crystalline lenses, the peripheral nerves, the kidney, etc. of diabetics including galactosemiacs thus causing the above described complications e.g. retinopathy, diabetic cataract, nerve disturbances or renal disorders (see Jap. J. Opthamol., 20, 399 (1976), Int. Congr. Ser. Excepta Med., 403, 594 (1977) and Metabolism, 28, 456 (1979)).

The compounds of the present invention have inhibitory activity on an aldose reductase and are therefore effective for the prevention and/or treatment of diabetic complications described above in mammals including human beings especially human beings.

The compounds of the present invention of the general formula (I) may form salts at the carboxy or tetrazolyl moiety.

By converting into salts, solubility of the compounds of the present invention in water can be increased, and therefore may be more readily administered as pharmaceuticals.

The compounds of the present invention may easily be converted into corresponding salts by the methods known per se, e.g. methods described hereafter.

The salts in the present invention are preferably non-toxic ones. The non-toxic salts mean salts of cations that are relatively innocuous to living body (animals including human beings) tissues and that the effective pharmacological properties of the compounds of the general formula () are not impaired by side effect(s) resulting from the cations when used in an amount required for the prevention and/or treatment. And water-soluble salts are preferable.

Suitable salts include, for example, a salt of an alkali metal such as sodium, potassium, a salt of an alkaline metal such as calcium, magnesium, an ammonium salt and a pharmaceutically acceptable (non-toxic) amine salt.

Amines suitable for forming such salts with carboxylic acid or tetrazolyl group are well known and include, for example, those amines which are theoretically obtained by substituting one or more of hydrogen atom(s) of ammonia by other group(s). These groups, which may be the same or different when one or more hydrogen atom(s) are substituted, are selected from, for example, alkyl group(s) of from 1 to 6 carbon atom(s) and hydroxyalkyl group(s) of from 1 to 3 carbon atom(s). Suitable non-toxic amine salts include salts of a tetraalkylammonium group, such as tetramethylammonium salt and salts of an organic amine, such as methylamine, dimethylamine, cyclopentylamine, benzylamine, phenethyl-amine, piperidine, monoethanolamine, diethanolamine, lysine and alginine.

Salts can be obtained from the compounds of the present invention of the general formula (I), by methods known per se, for example, by reacting the compound of the general formula (I) and a suitable base such as a hydroxide or carbonate of an alkali metal or alkaline earth metal, ammonium hydroxide, ammonia or an organic amine in theoretical amounts in an appropriate solvent.

The salts can be isolated by freeze-drying the solution, or by filtration if the salts are sufficiently insoluble to the reaction solution, or if necessary, by removing part of the solvent followed by filtration.

The compounds of the present invention possess an antagonistic activity on leukotrienes, inhibitory activity on phospholipase, on 5.alpha.-reductase and on aldose reductase.

In a standard laboratory test, for example, the compounds of the present invention showed the pharmaceutical activity in the following tables.

The compounds of the present invention showed an antagonistic activity on LTD.sub.4 in vitro (method is described hereafter), shown in the following tables.

As is obvious from the Tables I and II, compounds of 1,4-benzodioxane skelton having any substituent R, represented by the general formula (IA') or (IA") among the compounds of the present invention (i.e. the case when B and R.sup.4 are fixed and R.sup.1 and A are changed in the general formula (I)) have enough activity for pharmaceutical use.

And from Table III, it is confirmed if alkylene moiety (corresponding to A in the general formula (I)) would be converted, compounds having the enough pharmaceutical activity are given.

In the following tables, the comparision of activity by skeleton structure changes are shown.

And further, from Tables IV, V and VI, it can be clear that compounds in which the basic structural skeleton contains various rings also possess enough activity compared with the compounds having 1,4-benzodioxane skeleton (i.e. the case that R.sup.1 and A are fixed and B and R.sup.4 are changed).

According to the points above described, it is estimated fairly that replacement of an essential skeleton structure of a certain compound from 1,4-benzodioxane to various rings and/or change of the groups of general formula: R.sup.1 --A-- in the general formula (I) also leads to a compound having enough activity for pharmaceutical use.

From the arguments above described, it is fully expected that the full scope of the present invention has effective activity and therefore are useful as a pharmaceutical agent.

Antagonistic activity of the compounds of the present invention on LTD.sub.4 were measured by the following method.

A segment of ilem (2.5 cm) was removed from guinea pig 300-400 g and suspended in a Magnus tube containing Tyrodes solution. The tube was maintained at 37.degree. C. and aerated with 95% O.sub.2 -5% CO.sub.2. After stabilizing from 30 mins, 5.times.10.sup.-9 g/ml of LTD.sub.4 was added to the Magnus tube. Contraction length at the time and contraction lengths when the compounds of the present invention were challenged at some concentrations were measured, and the IC.sub.50 value were calculated.

(2) Inhibitory activity on 5.alpha.-reductase in vitro

The compounds of the present invention showed an inhibitory activity on 5.alpha.-reductase in vitro (method is described hereafter), shown in the following table.

Inhibitory activity of the compounds of the present invention on 5.alpha.-reductase was measured by the following method.

C. for 60 mins. The reaction was stopped by adding solution of chloroform-methanol (1:2). The reaction mixture was centrifuged and the supernatant was separated by thin layer chromatography on silica gel using chloroform-methanol-acetic acid (99.2:0.6:0.2) as a developing solvent. Radioactivity of formed 5.alpha.-dihydrotestosterone was measured by TLC scanner. The values of IC.sub.50 were determined by the inhibition percents of 5.alpha.-reductase activity measured by the above procedure (see Endocrinal, Japon., 18, 179 (1971).).

On the other hand, it was confirmed that the acute toxicity (LD.sub.50) over the full scope of the present invention was more than 500 mg/kg animal body weight by intravenous administration. Therefore, the compounds of the present invention may be considered to be sufficiently safe and suitable for pharmaceutical use.

For example, the values of LD.sub.50 of the compounds prepared in Examples 1(76), 1(212), 1(230) and 1(247) were more than 1000 mg/kg animal body weight by intravenous administration in male mice weighing 170-180 g, respectively.

The present invention is also related to methods of use as a leukotriene antagonist, phospholipase inhibitor, 5.alpha.-reductase inhibitor and/or aldose reductase inhibitor.

Sodium azide (490 mg) and pyridinium chloride (870 mg) were added to a solution of 8-(3-methoxy-4-pentyloxycinnamoyl)amino-1,4-benzodioxane (560 mg; synthesized in reference example 2) in dry dimethylformamide (3 ml). In an atmosphere of argon, the solution was stirred for 1.5 hrs at 100.degree. C. The reaction solution cooled to room temperature was poured into 1N hydrochloric acid, and the mixture was extracted with ethyl acetate. The extract was washed with water and a saturated aqueous solution of sodium chloride, dried, and then concentrated under reduced pressure.
