     SUMMARY 
     This invention is related to phenylalkan(en)oic acids which are useful for medicines. 
     More particularly, this invention is related to: 
     1) phenylalkan(en)oic acids of the formula: ##STR2## (wherein all of the symbols are the same meanings as hereinafter defined) and non-toxic salts thereof, 
     2) processes for the preparation of them and 
     3) antagonistic agents on leukotriene (abbreviated as LT hereinafter) B 4  containing them as active ingredient. 
     BACKGROUND 
     The metabolic routes, in which various compounds are biosynthesized from the same mother compound, i.e. arachidonic acid, are called &#34;Arachidonate cascade&#34; as a whole. 
     Arachidonic acid is metabolized by the action of lipoxygenase, e.g. 5-lipoxygenase, 12-lipoxygenase, and 15-lipoxygenase, to 5-hydroperoxyeicosatetraenoic acid (abbreviated as HPETE hereinafter), 12-HPETE and 15-HPETE, respectively. 
     These HPETEs are converted into 5-hydroxyeicosatetraenoic acid (abbreviated as HETE hereinafter), 12-HETE and 15-HETE, respectively, by the action of peroxidase which convert a hydroperoxy group to a hydroxy group. Furthermore, LTA 4  is also produced from 5-HPETE. LTA 4  is converted into LTB 4  and LTC 4 . LTC 4  is converted into LTD 4  by the action of λ-glutamyl transpeptidase. Moreover, it has been defined that LTD 4  is metabolized to LTE 4  (see Biochem. Biophys. Res. Commun., 91, 1266 (1979) and Prostaglandins, 19 (5), 645 (1980)). 
     Moreover, the action of LTB 4  has been gradually identified recently. Namely, it as been identified that LTB 4  having the following structure: ##STR3## (wherein the double bonds between 6th- and 7th-carbon, 8th- and 9th-carbon, 10th- and 11th-carbon and 14th-and 15th-carbon, are Z, E, E and Z, respectively), possesses a powerful action of polymorphonuclear leukocytes (PMNLs) accumulation and PMNLs adhesion, and PMNLs degranulation (see Nature, 286, 264 (1980), Proc. Nat. Acad. Sci. USA, 78, 3887 (1981) and J. Biol. Chem., 256, 5317 (1981)). Moreover it has been considered that LTB 4  promotes the release of arachidonic metabilites by attacking various cells as it has the powerful action like calcium ionophore (see J. Biol. Chem., 257, 4746 (1982)). 
     Moreover, LTB 4  in high concentration has been detected at the sites of various inflammation, for example, rheumatism, spinal arthritis (see Klickstein L. B., Shapleigh, C. and Goetzl, E. J. (1980) J. Clin. Invest., 66, 1166-1170), gout (Rae, S. A., Davidson, E. M. and Smith, M. J. H. (1982) Lancet II 1122-1123), psoriasis (see Grabbe, J., Czarnetzki, B. M., Rosenbach, T. and Mardin, M. (1984) J. Invest. Dermatol., 82, 477-479), ulceractive colitis (see Sharon, P. and Stenson, W. F. (1984) Gastroenterology 86, 453-460), respiratory disease (see O&#39;Driscoll, B. R., Cromwell, O. and Kay, A. B. (1984) Clin. Exp., Immunol., 55, 397-404). The fact described above shows that LTB 4  is deeply related to various inflammation. 
     Accordingly, the antagonistic agents on LTB 4  are considered to be useful as anti-inflammatory agents and antiallergic agents.

     COMPARISON WITH RELATED ARTS 
     The compounds of the formula (I), of the present invention are quite novel. 
     More concretely, the compounds wherein W represents an alkylene, of the present invention are quite novel in structure. Furthermore, it can not be expected from the information of the related arts that the compounds having these structures, possess an antagonism on leukotriene B 4 . 
     The compounds wherein W represents a phenylene or the group of the formula: ##STR20## of the present invention are also quite novel. The compounds of the formula (d) have the structure in which the group corresponding to A in the formula (I) is carbonyl group, and those of the formula (e) have the structure in which the group corresponding to A in the formula (I) is oxy, carbonyl, methylene or hydroxymethylene group. On the other hand, the compounds wherein W represents a phenylene or the group of the formula: ##STR21## of the present invention, have the group of the formula: --NHCO-- or --NHSO 2  -- as the group A. Therefore, the compounds of the present invention are quite different from the related arts in structure in that the groups shown by A represent quite different groups. 
     Furthermore, it can not be expected that an antagonism on leukotriene B 4  was held in the compounds wherein oxy, carbonyl, methylene or hydroxymethylene group is replaced by the groups of the formula --NHCO-- or --NHSO 2  --.

     The compounds of the formula (I) may be converted into the corresponding salts by the known method. Non-toxic and water-soluble salts are preferable. Suitable salts, for example, are followings: 
     salts of alkaline metal (sodium, potassium etc.), 
     salts of alkaline earth metal (calcium, magnesium etc.), ammonium salts, salts of pharmaceutically acceptable organic 
     amine (tetramethylammonium, triethylamine, methylamine, 
     dimethylamine, cyclopentylamine, benzylamine, phenethylamine, 
     piperidine, monoethanolamine, diethanolamine, 
     tris(hydroxymethyl)amine, lysine, arginine, N-methyl-D-glucamine etc.).

     STARTING MATERIALS 
     The starting materials and each reagents in the present invention are known or may be prepared by the known methods. 
     EFFECT 
     An antagonism on leukotriene B 4  of the compounds of the present invention has been confirmed by the following experimental results. 
     I) BINDING AFFINITY OF  3  H-LTB 4  ANTAGONIST TO HUMAN PMNL LTB 4  RECEPTOR 
     Human PMNLS (1×10 7  cells) were incubated with 1 nM  3  H-LTB 4  in Hanks balanced salt solution (1 ml) at 4° C. for 20 min. in the presence or absence of increasing concentrations of unlabeled LTB 4  of various compounds. Free  3  H-LTB 4  was separated from PMNLs-bound ligands by vacuum filteration through Whatman GF/B or C glass fiber filters. The filters were then washed rapidly 4 times with 2.5 ml of the ice-cold phosphate buffered saline. The radioactivity retained in the filter was determined by liquid scintillation counting. Specific binding was defined as the difference between total binding and binding in the presence of 3 μM LTB 4  (nonspecific binding). The inhibitory effect of specific  3  H-LTB 4  binding was calculated from the following equation. 
     
         The percentage of inhibition (%)=100-(B.sub.1 /B.sub.0 ×100) 
    
     B 1  : specific  3  H-LTB 4  binding in presence of antagonist 
     B 0  : specific  3  H-LTB 4  binding in absence of antagonist
