Description: (a) Field of the Invention The present invention relates to pharmaceutical agents (compounds) which act as leukotriene B₄ (LTB₄) antagonists in mammals. The compounds of the present invention are useful in treating inflammatory conditions in mammals such as psoriasis, Crohn's disease, ulcerative colitis and the like. (b) Prior Art LTB₄ (Formula I) is an arachidonic acid metabolite which is an important mediator of inflammation in mammals. As a mediator of inflammation LTB₄ is known to induce chemotaxis, chemokinesis aggregation, and degranulation of leukocytes in vitro , and to induce accumulation of polymorphonuclear leukocytes, and increase vascular permeability and edema formation in vivo . Particularly high levels of LTB₄ are detected in lesions in inflammatory diseases such as rheumatoid or spondylarthritis, gout, psoriasis, ulcerative colitis, Crohn's disease, and some respiratory diseases. Accordingly, it is an object of this invention to produce compounds for use as pharmaceutical agents which will exhibit LTB₄ antagonist activity in mammals. A potential LTB₄ antagonist (Formula II), which is structurally different from the compounds of the present invention, is disclosed in Biochem. and Biophys. Res. Comm., 138 540-546 (1986). In this article, the authors also suggest that they have found antagonistic activity in a series of unidentified unsaturated dihydroxy fatty acid derivatives which are to be the subject of a future publication. The pharmacology of the biologically active leukotrienes is generally discussed in J. Clin. Invest. 73 , 889.897 (1984). The J.Chem.Soc.Perk.Trans. I, 1987, published July, 1987 after the 1st and before the 2nd priority of the present application discloses a method for preparing LTB₄-antagonists with a basic phenyl or pyridyl group. These are structurally different from the presently claimed relevant compounds having a basic thienyl group belonging to the present 2nd priority compounds. Said document does not give any hint how to modify known LTB₄-antagonists to obtain highly useful antiinflammatory agents. The J. Org. Med. Chem., 1986, pages C35-C38 describes an improved procedure for the generation and selective trapping of 2,4'-dilithiophenylethyne, among others the preparation of methyl-7-[4-(hydroxynonyl)phenyl]-5-hydroxy-6-heptynoate. The reference, however, is silent about any pharmaceutical efficacy of the said compound. SUMMARY OF THE INVENTION This invention encompasses compounds of the formula and the pharmaceutically acceptable non-toxic addition salts thereof; wherein R¹ is lower alkyl having 1-10 carbon atoms; lower alkenyl having 2-10 carbon atoms; lower alkynyl and having 2-10 carbon atoms; lower alkadienyl having 3-10 carbon atoms; lower alkadiynyl having 4-10 carbon atoms; or alkenynyl having 4-10 carbon atoms; wherein R² and R³ are the same or different and represent hydrogen or lower alkyl having 1-6 carbon atoms; wherein X is CH=CH, S, or O; wherein Y is CH=CH or C≡C; wherein Z is OR⁴ or NR⁵R⁶, and wherein R⁴ represents H, lower alkyl having 1-6 carbon atoms, or a pharmaceutically acceptable cation, and wherein R⁵ and R⁶ act independently and represent H or lower alkyl having 1-6 carbon atoms, or R⁵ and R⁶ may act together with N to form a cycloamine of the formula: wherein q is an integer from 2-5; wherein m and n are the same or different and either 1 or 0; and wherein p is an integer from 1 to 5. The invention does not encompass the known compound methyl-7-[4-(hydroxynonyl)phenyl]-5-hydroxy-6-heptynoate, but is directed to the use of said compound as LTB₄-antagonist. DETAILED DESCRIPTION This invention encompasses compounds of Formula III as previously described including any stereoisomers thereof. A particularly preferred embodiment of the present invention is encompassed by a compound of the formula: wherein R¹, R², R³, Y, Z, R⁴, R⁵, R⁶, m, n, p, and q are as previously defined for Formulas III and IV and with the exception as indicated. The term "alkyl" as used to described R¹, R², R³, R⁴, R⁵, and R⁶ means straight or branched chain alkyls having 1-10 carbon atoms. The term "alkenyl" as used to describe R¹ means straight or branched chain alkenyls having 2-10 carbon atoms. The term "alkynyl" as used to describe R¹ means straight or branched chain alkynyls having 2-10 carbon atoms. The term "alkadienyl" as used to describe R¹ means straight or branched chain alkadienes, including allenes, having 3-10 carbon atoms. The term "alkadiynyl" as used to describe R¹ means straight or branched chain alkadiynyls having 4-10 carbon atoms. The term "alkenynyl" as used to describe R¹ means straight or branched chain alkenynyls having 4-10 carbon atoms. The term "pharmaceutically acceptable cations" as used to describe R⁴ refers to cations such as ammonium, sodium, potassium, lithium, calcium, magnesium, ferrous, zinc, copper, manganous, aluminum, ferric manganic, ammonium, tetraalkyl-ammonium and the like. The term "pharmaceutically acceptable non-toxic addition salts" refers either to those base derived salts of any compound herein having a carboxylic acid function. The base derived salts may be derived from pharmaceutically acceptable non-toxic inorganic or organic bases. Among the inorganic bases employed to produce said pharmaceutically acceptable salts are the hydroxide bases of the "pharmaceutically acceptable cations" disclosed above. Among the organic bases employed to produce said pharmaceutically acceptable salts are the pharmaceutically acceptable non-toxic bases of primary, secondary, and tertiary amines. Especially preferred non-toxic bases are isopropylamine, diethylamine, ethanolamine, dicyclohexylamine, choline, and caffeine. All the pharmaceutically acceptable non-toxic addition salts are prepared by conventional processes well known to those of ordinary skill in the art. The compounds of this invention are generally prepared by separately adding two chains to an appropriately substituted aromatic moiety. The first chain can be added by initially performing a nucleophilic addition of a bromoalk-1-yne compound, such as via a Grignard reaction to a bromo-substituted aromatic aldehyde. The aromatic moiety can be phenyl, thienyl or furyl. The Grignard reagent adds to the aldehyde group to form an alkynol compound. The resulting hydroxyl group is typically protected by reaction with a trialkylchlorosilane, preferably t-butyldimethylchlorosilane. The length of the alkyne side chain can be optionally increased to produce an R¹ of the desired length. One method of increasing the chain length is to convert the terminal acetylene into an anion by reaction with an alkyl lithium compound in an aprotic solvent. This anion can then be added to a straight or branched chain alkyl iodide via a nucleophilic substitution. By varying the chain lengths of the bromoalkyne and the iodide compound in the above reaction, the necessary variations can be achieved to produce the R¹ substituents claimed in this invention. The second chain can be added to the above aromatic moiety via a catalytic reaction. By selecting a hydroxyester containing a terminal triple bond and by protecting the hydroxyl group with a trialkylsilane, preferably t-butyldimethylchlorosilane, one can substitute the terminal acetylene for the bromo on the aromatic moiety. By varying the chain length and the position of the hydroxyl group, one can achieve the necessary variations to produce diyne compounds encompassed by the present invention. The diyne compounds can be catalytically hydrogenated over Lindlar catalyst to produce diene compounds also encompassed by the present invention. The biological activity possessed by the compounds of this invention was indicated by positive results to the "LTB₄ Receptor Binding Assay" and the "Human Neutrophil Degranulation Assay". Preparation of Human Neutrophils : For use in both the "LTB₄ receptor Binding Assay" and the "human Neutrophil Degranulation Assay", neutrophils were purified from venous blood of normal human donors using standard techniques of dextran sedimentation, centrifugation on Histopaque® (density solution) and hypotonic lysis of erythrocytes (Boyum, A., Isolation of Leukocytes From Human Blood: Further Observations . Scand. J. Lab. Clin. Inves. 21 (Suppl. 97): 31, 1968). The purity of isolated neutrophils was ≧ 95%. LTB₄ Receptor Binding Assay : Neutrophils (4-6x10⁶) in 1ml of Hanks' balanced salt solution containing 10mM Hepes Buffer (HBSS), pH 7.4 and 30 µM nordihydroguaiaretic acid were incubated with 0.6nM (³H) LTB₄ in the presence or absence of test compounds. The incubation was carried out at 0°C for 45 minutes and terminated by adding 5ml of ice-cold HBSS followed by rapid filtration of incubation mixture under vacuum through GF/C glass fiber filters. The filters were further washed with 10ml HBSS and their radioactivity was determined. Specific binding was defined as the difference between total binding and nonspecific binding which was not displaced by 10-⁷M unlabeled LTB₄. The inhibition of specific binding was determined for representatives compounds of this invention, and the corresponding IC₅₀ values calculated (Table 1). An IC₅₀ is the concentration of the compound of interest which will inhibit the binding of LTB₄ by 50% of the LTB₄ receptors. For example, for the compound of Example 7, the IC₅₀ was determined to be approximately 5µM. Human Neutrophil Degranulation Assay : LTB₄ induced neutrophil degranulation was determined by measuring the release of myeloperoxidase activity into the incubation medium. Neutrophils (3 x 10⁶) in 1ml HBSS solution were preincubated with cytochalasin B(5µg) at 37°C for 5 minutes, followed by preincubation with test compounds for 7 minutes. Neutrophils were then incubated for 2 to 20 minutes with either LTB₄(5 x 10⁻⁸M) or the chemotactic peptide f-met-leu-phe (5 x 10⁻⁶M) to induce degranulation. Following incubation, samples were centrifuged and myleoperoxidase was extracted from the cell pellets by sonication in phosphate buffer containing 0.4% Triton X-100. Triton X-100 was also added to the supernatents to a concentration of 0.4%. The supernatants and the pellet extracts were then assayed spectrophotometrically for myeloperoxide activity by determining the rate of decomposition of H₂O₂ with o-dianisidine as hydrogen donor as described by Renlund D.G., MacFarlane J.L., Christensen, R.D., Lynch R.E., and Rothstein, G., A Quantitative And Sensitive Method For Measurement Of Myeloperoxidase , Clinical Research 28:75A, 1980). Myeloperoxidase activity released into the supernatant was expressed as the percent of the average total activity (pellet plus supernatant). The inhibition of LTB₄ induced neutrophil degranulation was determined for representative compounds of this invention and their corresponding IC₅₀ values were calculated (Table 1). The concentration of a compound which inhibited LTB₄ induced neutrophil degranulation by 50% was determined to be its IC₅₀ value. By virtue of their activity as LTB₄ antagonists, the compounds of Formula I are useful in treating inflammatory conditions in mammals such as psoriasis, Crohn's disease, ulcerative colitis and the like. A physician or veterinarian of ordinary skill can readily determine whether a subject exhibits the inflammatory condition. The preferred utility relates to treatment of ulcerative colitis. The compounds of the present invention can be administered in such oral dosage forms as tablets, capsules, softgels, pills, powders, granules, elixirs, or syrups. The compounds may also be administered intravascularly, intraperitoneally, subcutaneously, intramuscularly, or topically using forms known to the pharmaceutical art. In general, the preferred form of administration is oral. For the orally administered pharmaceutical compositions and methods of the present invention, the foregoing active ingredients will typically be administered in admixture with suitable pharmaceutical diluents, excipients, or carriers (collectively referred to herein as "carrier" materials) suitably selected with respect to the intended form of administration, that is, oral tablets, capsules, softgels, elixirs, syrups, drops, and the like, and consistent with conventional pharmaceutical practices. For example, for oral administration in the form of tablets or capsules, a therapeutically effective amount of one or more compounds of the present invention may be combined with any oral non-toxic pharmaceutically acceptable inert carrier such as lactose, starch, sucrose, cellulose, magnesium stearate, dicalcium phosphate, calcium sulfate, mannitol, and the like, or various combinations thereof. For oral administration in liquid forms, such as in softgels, elixirs, syrups, drops and the like, a therapeutically effective amount of the active drug components may be combined with any oral non-toxic pharmaceutically acceptable inert carrier such as water, saline, ethanol, polyethylene glycol, propylene glycol, corn oil, cottonseed oil, peanut oil, sesame oil, benzyl alcohol, various buffers, and the like, or various combinations thereof. Moreover, when desired or necessary, suitable binders, lubricants, disintegrating agents, and coloring agents can also be incorporated in the mixture. Suitable binders include starch, gelatin, natural sugars, corn sweeteners, natural and synthetic gums such as acacia, sodium alginate, carboxymethylcellulose, polyethylene glycol, and waxes or combinations thereof. Lubricants for use in these dosage forms include boric acid, sodium benzoate, sodium acetate, sodium chloride, and the like or combinations thereof. Disintegrators include, without limitation, starch, methylcellulose, agar, bentonite, guar gum, and the like, or combinations thereof. Sweetening and flavoring agents and preservatives can also be included where appropriate. For intravascular, intraperitoneal, subcutaneous, or intramuscular administration, one or more compounds of the present invention may be combined with a suitable carrier such as water, saline, aqueous dextrose, and the like. For topical administration, such as for psoriasis, therapeutically effective amounts of one or more compounds of the present invention can be combined with pharmaceutically acceptable creams, oils, waxes, gels and the like. Regardless of the route of administration selected, the compounds of the present invention are formulated into pharmaceutically acceptable dosage forms by conventional methods known to those skilled in the art. The compounds may also be formulated using pharmacologically acceptable base addition salts. Moreover the compounds or their salts may be used in a suitable hydrated form. Regardless of the route of administration selected, a non-toxic but therapeutically effective quantity of one or more compounds of this invention is employed in any treatment. The dosage regimen for preventing or treating inflammatory conditions with the compounds of this invention is selected in accordance with a variety of factors, including the type, age, weight, sex, and medical condition of the patient, the severity of the inflammatory condition, the route of administration, and the particular compound employed in the treatment. A physician or veterinarian of ordinary skill can readily determine and prescribe the effective amount of the drug required to prevent or arrest the progress of the condition. In so proceeding, the physician or veterinarian could employe relatively low doses at first and subsequently increase the dose until a maximum response is obtained. Daily dosages of the compounds of the invention are ordinarily in the range of about 1.0 mg/kg up to about 21.0 mg/kg, [preferably in the range of about 2.0 to 14.0 mg/kg (orally)]. The following examples illustrate the methods used to prepare the compounds of this invention. In the following examples, and throughout this application a wavey line ( ) defines a substituent as having optional R or S stereochemistry. A broken triangular shaped line ( ) defines the substituent at the base of the triangle as coming out of the plane of the paper, whereas a substituent at the apex of the broken triangle, is defined as going into the plane of the paper. DESCRIPTION OF THE PREFERRED EMBODIMENT Example 1 1-(p-bromophenyl)-but-3-yn-1-ol To 4.1g of flame dried Mg was added 50ml of diethyl ether ("ether") followed by the addition of a few iodine crystals. To this was added a 10ml aliquot of a solution containing 15ml (168.9 mmol) of propargyl bromide in 50ml of ether. The reaction was started by the addition of 25mg of HgCl₂. The remaining solution of propargyl bromide in ether was then added at a rate sufficient to maintain a steady reflux. Once addition was complete, the mixture was stirred 1 hour at room temperature (R.T.) and then placed in an ice bath and cooled to 0°C. To the cooled reaction mixture was added dropwise with stirring over a 1 hour period, a solution containing 25g (135.1 mmol) of 4-bromobenzaldehyde dissolved in 30ml of ether and 30ml of THF. Once addition was complete, the ice bath was removed and the reaction mixture stirred overnight at room temperature (R.T.). The reaction was quenched with a saturated NH₄Cl solution. The layers were separated and the aqueous layer was extracted twice with ether. The combined extracts were washed 1X each with H₂O, and brine and then dried (MgSO₄). Removal of the solvent produced 30.2g of a crude yellow oil which was semi-purified by high pressure liquid chromatography, HPLC, (silica; gradient elution with methyl t-butyl ether-hexane) to yield 20.8g of a reaction mixture that was 80% pure in the titled product. Example 2 1-(p-bromophenyl)-1-(t-butyldimethylsiloxy)-3-butyne TBDMSO = t-butyldimethylsiloxy A solution containing 19g (84.5 mmol) of the semi-purified reaction product of Example 1 dissolved in 50ml of DMF was cooled to 0°C (ice bath) and 12.9g (190 mmol) of imidazole was added in one portion. The reaction mixture was stirred 10 minutes until all the imidazole dissolved and then was added in one portion 14.3g (95 mmol) of t-butyldimethylchlorosilane. After stirring for 5 minutes, the ice bath was removed and the reaction mixture was stirred for an additional 2 hr. at R.T. The reaction was then poured into 500ml of ether and washed 3x with 50cc of H₂O and 1x with 100ml of brine. The organic layer was then separated, dried (MgSO₄), and removal of all solvent yielded 29.32g of crude product. Separation by reverse phase HPLC (gradient elution with acetonitrile-water) yielded 9.1g of the titled product. Analysis for C₁₆H₂₃OSiBr (MW = 339.35): Calcd: C, 56.63; H, 6.83; Br, 23.55.

Upon addition, the reaction was warmed to -10°C and stirred at -10°C for 30 min. Iodopentane (1.2ml, 9.0 mmol) was then added followed by 5.0ml of hexamethylphosphoric triamide (HMPA) whereupon the reaction mixture was warmed to R.T. and stirred overnight. The reaction was quenched with about 5.0ml of H₂O, then poured into hexane and washed 4x with H₂O, and 1x with brine. The organic layer was dried (MgSO₄) and the solvent removed to yield a dark red oil which was purified by medium pressure liquid chromotography (MPLC) eluting with hexane to yield 2.14g of the titled product as a pale yellow oil. 1H N.M.R δ TMS CDCl₃ (300 MHz): -0.08(s,3H); 0.03(s,3H); 0.9(s&t, 12H); 1.3(br.m,4H); 1.43(br.m,2H); 2.1(tt,2H); 2.45(m,2H); 4.72(t,1H); 7.32(dd,4H).
