The salts of the above benzo (b) thiophene compounds represented by formulae (I), (II), (II'), (III), (Illb), and (IV) are an additional aspect of the invention. In those instances when the compound of the invention possesses acidic or basic functional groups, various salts may be formed which are more water soluble, and more physiologically suitable than the parent compound. Representative pharmaceutically acceptable salts, include but are not limited to, the alkali and alkaline earth salts such as lithium, sodium, potassium, calcium, magnesium, aluminum and the like. Salts are conveniently prepared from the free acid by treating the acid in solution with a base or by exposing the acid to an ion exchange resin. Included within the definition of pharmaceutically acceptable salts are the relatively non-toxic, inorganic and organic base addition salts of compounds of the present invention, for example, ammonium, quaternary ammonium, and amine cations, derived from nitrogenous bases of sufficient basicity to form salts with the compounds of this invention (see, for example, S. M. Berge, et al . , "Pharmaceutical Salts," J. Phar. Sci., 66: 1-19 (1977)). Moreover, the basic group (s) of the compound of the invention may be reacted with suitable organic or inorganic acids to form salts such as acetate, benzenesulfonate, benzoate, bicarbonate, bisulfate, bitartrate, borate, bromide, camsylate, carbonate, chloride, clavulanate, citrate, chloride, edetate, edisylate, estolate, esylate, fluoride, fumarate, gluceptate, gluconate, glutamate, glycolylarsanilate, hexylresorcinate, bromide, chloride, hydroxynaphthoate, iodide, isothionate, lactate, lactobionate, laurate, malate, malseate, mandelate, mesylate, methylbromide, methylnitrate, methylsulfate, mucate, napsylate, nitrate, oleate, oxalate, palmitate, pantothenate, phosphate, polygalacturonate, salicylate, stearate, subacetate, succinate, tannate, tartrate, tosylate, trifluoroacetate, trifluoromethane sulfonate, and valerate . Certain compounds of the invention may possess one or more chiral centers, and thus, may exist in optically active forms. Likewise, when the compounds contain an alkenyl or alkenylene group there exists the possibility of cis- and trans- isomeric forms of the compounds. The R- and S- isomers and mixtures thereof, including racemic mixtures as well as mixtures of cis- and trans- isomers, are contemplated by this invention. Additional asymmetric carbon atoms can be present in a substituent group such as an alkyl group. All such isomers as well as the mixtures thereof are intended to be included in the invention. If a particular stereoisomer is desired, it can be prepared by methods well known in the art by using stereospecific reactions with starting materials which contain the asymmetric centers and are already resolved or, alternatively by methods which lead to mixtures of the stereoisomers and subsequent resolution by known methods. For example, a racemic mixture may be reacted with a single enantiomer of some other compound. This changes the racemic form into a mixture of stereoisomers and diastereomers, because they have different melting points, different boiling points, and different solubilities and can be separated by conventional means, such as crystallization. Prodrugs are derivatives of the compounds of the invention which have chemically or metabolically cleavable groups and become by solvolysis or under physiological conditions the compounds of the invention which are pharmaceutically active in vivo. Derivatives of the compounds of this invention have activity in both their acid and base derivative forms, but the acid derivative form often offers advantages of solubility, tissue compatibility, or delayed release in a mammalian organism (see, Bundgard, H., Design of Prodrugs, pp. 7-9, 21-24, Elsevier, Amsterdam 1985) . Prodrugs include acid derivatives well known to practitioners of the art, such as, for example, esters prepared by reaction of the parent acidic compound with a suitable alcohol, or amides prepared by reaction of the parent acid compound with a suitable amine. Simple aliphatic or aromatic esters derived from acidic groups pendent on the compounds of this invention are preferred prodrugs. In some cases it is desirable to prepare double ester type prodrugs such as (acyloxy) alkyl esters or ( (alkoxycarbonyl) oxy) alkyl esters. Particularly preferred esters as prodrugs are methyl, ethyl, propyl, isopropyl, n-butyl, isobutyl, tert-butyl, morpholinoethyl, and N,N-diethylglycolamido. N,N-diethylglycolamido ester prodrugs may be prepared by reaction of the sodium salt of a compound of Formula (I) (in a medium such as dimethylformamide) with 2-chloro-N,N- diethylacetamide (available from Aldrich Chemical Co., Milwaukee, Wisconsin USA; Item No. 25,099-6). Morpholinylethyl ester prodrugs may be prepared by reaction of the sodium salt of a compound of formula (I) (in a medium such as dimethylformamide) 4- (2-chloroethyl)morpholine hydrochloride (available from Aldrich Chemical Co., Milwaukee, Wisconsin USA, Item No. C4 , 220-3) . (III) Method of preparing the benzo (b) thiophene-3- Glyoxylamide Compound (Starting Material for preparing other Compounds of the Invention) : The benzo (b) thiophene-3-glyoxylamide compounds are compounds of this invention and are also useful as - intermediates or staring materials for preparing other compounds of the invention. The benzo (b) thiophene-3- glyoxylamide compounds are prepared by following a protocol such as Scheme 1 below : Scheme 1 3 R= OH 5 R=0Me 4 R= OMe 6 R=OH 7 R=OAc 10 11 R=OMe 13 14 12 R=NH, 15 16 Synthesis of the starting material compounds useful for the present invention begins in one aspect with 6,7- dihydro-5H-benzo (b) thiophen-4-one compound of formula (1) or substituted derivatives thereof. The compound (1) is brominated with bromine in carbon tetrachloride at temperature ranging from about -30 °C to 30 °C, over a period of from about 2 to 30 hours. (see Fleming, I. and Goldhill Jr., J. J. C. S Perkin I, 1493, (1980)). The product (2) is aromatized using sodium carbonate and lithium bromide to afford the benzo (b) hiophene alcohol of formula (3) . The aromatization reaction requires heating in an anhydrous aprotic solvent such as for example, dimthylformamide. The product (3) may be isolated by aqueous work up. Procedures for aromatization of alicyclic ring compounds are known in the literature (see Advanced Organic Chemistry, J. March, Wiley interscience publishers, 3 rd edition, 1985, page 1052, and references therein) . The phenolic (OH group on benzo (b) thiophene) group may be protected for example, by alkylation. Other protecting groups i.e. organosilyl groups may also be used. To O-alkylated the benzo (b) thiophenol of formula (3) , it is reacted with an alkyl halide, preferably alkyl iodide and more preferably methyl iodide using a base such as potassium carbonate in a solvent such as acetone. This results in a compound of formula (4) or analog thereof, depending on the protecting group. Substitution at the 2 - position of the benzo (b) thiophene molecule may be effected by purchasing or preparing the starting material i.e. a compound (1) analog with that substitution already in place. Alternatively substitution at the 2 - position may be effected by generating a carbanion at the 2 - position, which then reacts as a nucleophile with an electrophilic substrate. For example, the nucleophile generated by reacting a compound of formula (4) with an alkyllithium reagent, for example, n-BuLi or other organometallic agent may be reacted with an electrophile source such as for example alkyl halide or arylhalide. A particularly preferred alectrophile source for this step is ethyl iodide, ethylbromide or methyl iodide. The use of ethyl bromide for example, results in a compound of formula (5) . One of skill in the art is aware that organolithium alkylation or arylation reactions are performed in anhydrous polar aprotic solvents such as for example tetrahydrofuran at temperatures ranging from about -80 °C to 20 °C, preferably -80 °C to -10 °C followed by aqueous or non-aqueous work-up procedures. The hydroxy protecting group (for example, methyl in compound of formula 5) is removed by basic hydrolysis. First, the salt is prepared by reacting compound (5) with a sodium hydride dispersion (or other suitable base) in dimethylformamide at about 155 °C preferably in an oil bath. After about 2 hours or upon satisfactory completion of reaction (as tested by disappearance of diagnostic marker for methoxy starting material) , the reaction mixture is cooled to about -30 to 20 °C. Aqueous acid, preferably 5N HCl is added slowly while maintaining the temperature at below about 30 °C. The resulting mixture is worked up under aqueous acidic conditions to afford the benzo (b) thiophenol compound of formula (6) . The compound of formula (6) is re-protected, preferably with an electron withdrawing group for example the acetyl group. This affords protection of the -OH group at position 4 or 5 depending on the starting material used, and simultaneous activation of the 3- position by making the hydrogen atom at the 3 -position more electron deficient. Acetylation is accomplished by reacting the compound of formula (6) with a base such as sodium hydroxide to form an alkoxide intermediate, followed by reaction with acetyl chloride for example, or other electron withdrawing protecting group, to form the compound of formula (7) or analog thereof. Having activated the 3-position on the benzo (b) thiophene ring from above, the acetylated benzothiophene compound (7) is halogenated, preferably brominated, at the 3- position by the use of n-bromosuccinimide or other appropriate halogenating agent. The bromination reaction involves stirring the mixture of reagents (compound 7, and n-bromosuccinimide) in a polar aprotic solvent from about 30 minutes to 20 hours. The reaction is typically complete in 1 to 4 hours. The resulting 3-bromo benzo (b) thiophene compound (8) may be isolated by chromatography or other known methods . The acetyl protecting group as in compound (8) , may be removed by treatment of a compound of formula (8) with an aqueous base solution. A preferred aqueous base solution is generated by addition of lithium hydroxide to a mixture of tetrahydrofuran, water and methanol . Other basic hydrolysis methods and reagents, are known to one of skill in the art. The incipient alkoxide (i.e. lithium alkoxide) may be isolated or converted to the free benzothiophenol by treatment with acid (e.g. HCl) . The benzothiophenol compound of formula (9) or analog thereof, may be isolated by non-aqueous methods, i.e. by concentration of the product mixture followed by chromatography. The benzo (b) thiophen-4-ol compound of formula (9) or analog thereof, is further elaborated or functionalized as desired, i.e. by forming an alkyl or aryl ether. A preferred protocol involves functionalization followed by protection or a simultaneous functionalization and protection as in the use of an acetal . For example, reaction of the compound of formula (9) with 2- bromomethyl-1 , 3-dioxolane and a base e.g. cesium carbonate, in an aprotic solvent results in the dioxolane compound of formula (10) . The compound of formula (10) from compound (9) serves to protect the incipient functionalized group at the 4 or 5 - position (depending on the benzothiophene starting material) and allows for elaboration of the bromo or halo group at the 3 - position. The halo group at the 3- position is then elaborated into desired functional groups. In particular, to prepare glyoxyl esters, a reagent such as dimethyloxalate is reacted with a carbanion generated by reaction of a compound of formula (10) with an alkyllithium e.g. n-butyllithium. The reaction of compound (10) with dimethyloxalate for example, affords a compound of formula (11) . The compound of formula (11) may be further elaborated to a compound of formula (12) for example, by reacting with excess ammonia, preferably under pressure. This may be accomplished by reacting compound (11) and ammonia in a pressure tube at about 30 to 80 °C for about 10 minutes to 4 hours, followed by appropriate cooling (i.e. about -78 °C) and isolation of product. Alternatively other methods of functionalizing the ester may be applied depending on substrate sensitivity. Other methods may include reagents for conversion of esters to amides (Larock, supra) i.e. the Weinreb amide procedure (supra) using substituted aluminoamide reagents, or conversion to activated esters followed by use of amide coupling agents . With or without further modifications at the 3- position, compound (11) or (12) may be reacted with aqueous acid to remove the acetal protecting group and provide for example, the aldehyde of compound (13) . The aldehyde (13) may be elaborated to the acid or other functional groups by methods known to one of skill in the art. For example, the aldehyde of formula 13 is converted to the free acid by oxidation. Various reagents are known in the art for aldehyde oxidations (see J. March, supra) . One example is the use of sodium hypochlorite in t-butyl alcohol buffered with sodium dihydrogen phosphate, to oxidize the aldehyde (13) to the acid (14) . The acid compound of formula (14) may be converted to an ester i.e. the methyl ester, or to an acid salt i.e. the sodium salt by methods known to one of skill in the art. The acid (14), the acid salt, i.e. sodium salt, the ester, i.e. methyl ester, are compounds of the invention and are also useful as starting materials for other compounds of the invention. For example, the compound of formula (14) may be converted to an amide or substituted amide, or acylamino acid derivative. Where a protected .amino acid is used the resulting acylamino acid compound (e.g. compound 15) is also a compound of the present invention. Methods of preparing amides and derivatives thereof, or acylamino acid derivative compounds of the invention i.e. compounds of formula (15) or (16) , are discussed herein and are generally known to one of skill in the art. Preparing the benzo (b) thiophene-3-glyoxylamide N- hydroxyfunctional amide compounds The benzo (b) thiophene-3-glyoxylamide N- hydroxyfunctional amide compounds of the invention are prepared from the methyl ester compound 1A (scheme 2, below) , or analogs thereof . The acid compound of formula (14) may be employed as starting material for the preparation of N-hydroxyfunctional amide compounds of the present invention by methods known to one of skill in the art . For example, in a protocol beginning with compound 14, the acid is converted to the N-hydroxyfunctional amide compound of formula (II'') (See scheme 2 below) Scheme 2 The above transformation may be accomplished by coupling the compound of formula 14 with a protected and/or substituted or unsubstituted hydroxylamine group or derivative, in the presence of a coupling agent. This results in a protected or unprotected N-hydroxyfunctional amide derivative of a compound of formula (II'') . For example, the acid compound of formula (14) is reacted with o- ( tert-butyldimethylsilyl) hydroxylamine at ambient temperature, in the presence of excess 2,4, 6-collidine (collidine) and benzotriazol-1-yl- oxytris (dimethylamino) phosphonium hexafluorophosphonate (coupling catalyst, see Tetrahedron Lett . , 1219 (1975)) to form after about 1-10 hours, the o- (tert- butyldimethylsilyl) substituted N-hydroxyfunctional amide derivative. The silyl or other protecting group is removed by well known methods such as for example, the use of trifluoroacetic acid to afford the desired N- hydroxyfunctional amide compound of formula (II'') wherein R 4a is hydroxy and R 4 -* 3 is hydrogen. Typically, the condensation or coupling is performed in a solvent such a dimethylformamide, tetrahydrofuran or aqueous mixtures of the like. In general, protic solvents are preferred for the purpose of this invention. The reaction is catalyzed by a base including weak organic or inorganic bases. Organic bases such as collidine are preferred. The reaction is also preferably run in the presence of agents that retard or reduce racemization of the hydroxyfunctional amide, the substituted hydroxylamine or its derivative. A particularly preferred agent for retarding racemeization where applicable, is benzotriazolyl-N-oxy-tris (dimethylamino) phosphonium hexafluorophosphate. Upon completion of the reaction, the mixture is concentrated in vacuo. The resulting product mixture is chromatographed or crystallized, e.g., by sonication to obtain the target compound. An alternate preparation method is the inter-conversion of compounds of the invention as shown for example in Scheme (3) : Scheme 3 These and other methods are well known in the arts and can be found in reference texts such as for example J. March Advanced Organic Chemistry, Wiley Interscience publishers, New York, N.Y, 1985, and R. C. Larock Comprehensive Organic Transformations , VCH Publishers, New York, N.Y, 1989. The protected intermediates to compounds of formula (II) are useful SPLA2 inhibitors and are also compounds of this invention. The benzo (b) thiophene-3 -acetamide SPLA2 inhibitors: Benzo (b) thiophene-3-acetamide SPLA2 inhibitors with the N-hydroxyfunctional amide, the acidic group or the acylamino acid group at the 4 or 5 position may be prepared from the dioxolane compound of formula (10) as shown below in scheme 4: Scheme 4 For example, the compound of formula (10) may be metallated, preferably lithiated by a halogen metal exchange reaction in THF for example, at about -10 °C to about -70 °C using for example, n-butyllithium to form the un-isolated intermediate compound (10a) . This is followed by addition of an allyl halide, preferably allyl iodide to form the terminal alkene compound (10b) . Upon ozonolysis of the terminal alkene compound (10b) using ozonolysis procedures known to one of skillin the art, i.e., ozone in methylene chloride at about -78 °C to about -20 °C, the aldehyde (10c) is obtained. The aldehyde (10c) is oxidized to the acid compound (lOd) using for example, sodium hypochlorite in a suitable solvent, i.e a protic solvent such as aqueous tertiary butyl alcohol preferably buffered with sodium dihydrogen phopshare, to form the acid compound (lOd) . The acid (lOd) is then amidated with ammonia in the presence of a coupling reagent e.g., BOP to form the acetamide compound (lOe) . Similarly other primary or secondary amines may be utilized in place of ammonia to afford the corresponding substituted acetamide compound. The acetamide compound (lOe) obtained from compound (10) as described above may be converted to the corresponding acidic group, N-hydroxyfunctional amide group, or acylamino acid group at the 4 or 5 position as described previously. Alternatively, the acetamide compounds i.e., compound (lOe) may be prepared by following a procedure according to Scheme 4a below: Scheme 4a 10 10a 10f HR 10d 10e Compound (lOd) may be prepared from compound (10) by halogen metal exchange at position 3 as described above to afford compound (10a) . This is followed by a nucleophilic ring opening of an added epoxide, e.g. ethylene oxide. The resulting alcohol compound (lOf) may be oxidized in one or two steps (directly or via the aldehyde) to the acid compound (lOd) . Methods for oxidation of alcohols to acids are well known to one of skill in the art, and are found in general reference texts (see Larock, infra) . The acid compound (lOd) is converted to the acetamide (lOe) or a substituted acetamide as described previously. Other methods of functionalizing the 3 -position of compound (10) , to an amide group may be found in R. C. Larock Comprehensive Organic Transformations, VCH Publishers, New York, N.Y, 1989. The benzo (b) thiophene-3-acetamide compound prepared as discussed above is then elaborated to the N-hydroxyfunctional amide derivative by following a sequence of Scheme 1, 2 or 3 to elaborate the 4 or 5 position to the desired N-hydroxyfunctional amide, acylamino acid or acidic group compound as described previously. Preparing the benzo (b) thiophen-3-oxime compounds: The benzo (b) thiophen-3-oxime compounds of the invention may be prepared following the protocol of scheme 5 below; Scheme 5 17 18 19 To introduce the oxime functionality, the methyl ester of the benzo (b) thiophene glyoxylamide compound (17) is heated with hydroxylamine hydrochloride (when R is H) in a THF/methanol mixture for about 1 to 8 hours or until the reaction is determined to be essentially complete. The reaction product is isolated by chromatography or other known laboratory procedure. Substituted oximes such as when R is methyl, ethyl, phenyl or other substituent may be prepared by reacting the corresponding substituted hydroxylamine hydrochloride or free base with the glyoxylamide as described supra . The ester functionality at the 4 or 5 position on the benzo (b) thiophene nucleus, as in for example, compound (18) , may be converted to the acid by hydrolysis using lithium hydroxide or other known ester hydrolysis methods to afford compounds of formula (19) . N- hydrofunctional-3-oxime amides and acylamino acid-3-oxime amides may be prepared by a protocol such as scheme (6) below. Scheme 6 The oxime amide compound of formula (19b) for example, may be converted to a N-hydroxyfunctional amide functionality directly or via the acid functionality (e.g. Compound (19b) , to afford for example the compound of formula (20) . Similarly, the oxime amide compound of formula (19b) may be converted to the acylamino acid compound of formula (20b) General procedures for the conversion of organic acids to amino acid are well known to artisans in the field, and have been documented in general reference texts including, for example, J. March Advanced Organic Chemistry, Wiley Interscience publishers, New York, N.Y, 1985, and R. C. Larock Comprehensive Organic Transformations, VCH Publishers, New York, N.Y, 1989. The oxime amide compounds of scheme 6 such as the methyloxime compound (19b) , can be converted to the corresponding acylamino acid or N-hydroxyfunctional amide derivative using the coupling reagent (BOP) . The formation of the N-hydroxyfunctional amide derivative may be accomplished by coupling with various substituted or unsubstituted hydroxylamine compounds by general coupling procedures as described for the glyoxylamime compounds supra . Similarly, the acylamino acid derivative may be prepared by BOP catalyzed coupling of an N-terminus protected amino acid with an oxime amide compound such as compound (19b) having an acid group at the 4 or 5 position of the benzothiophene nucleus . Such methods are known to one skilled in the art. Additional references, or procedures are found in J. March Advanced Organic Chemistry, Wiley Interscience publishers, New York, N.Y, 1985; R. C.

Davis, Editor, Oxford University Press Inc., New York, NY, 1992. The benzo (b) thiophene-3-glyoxylamide acylamino acid derivatives: The benzo (b) thiophene-3-glyoxylamide acylamino acid derivative compounds of the invention are prepared by room temperature base catalyzed condensation of the amino acid protected at the acid terminus by a protecting group known in the literature (preferably as the methyl ester) , with the benzo (b) thiophene-3-glyoxylamide acid derivative compound of formula (14) as shown in Scheme 7 below: Scheme 7 21 14 22 Typically, the condensation or coupling is performed in a solvent such as dimethylformamide, tetrahydrofuran or aqueous mixtures of the like. In general protic solvents are preferred for the purpose of this invention. The reaction is base catalyzed including weak organic or inorganic bases. Organic bases such as collidine are preferred. The reaction is also preferably run in the presence of agents that retard or reduce racemization of the amino acid or its derivative, such as for example, benzotriazolyl-N-oxy-tris (dimethylamino) phosphonium hexafluorophosphate (BOP) . Upon completion of the reaction, the mixture is concentrated in vacuo. The resulting product mixture is chromatographed to obtain the target compound. One of skill in the art is aware that the derivatives of the acid such as the acid salt or the methyl ester of the acid can be reacted with the amino acid or derivatives thereof to obtain the protected compound (21) or a corresponding derivative. Such methods are well known in the arts and can be found in reference texts such as for example J. March Advanced Organic Chemistry, Wiley Interscience publishers, New York, N.Y, 1985, and R. C. Larock Comprehensive Organic Transformations, VCH Publishers, New York, -N.Y, 1989. The protected compound of formula (21) and analogs thereof, are also useful S LA 2 inhibitors and are also compounds of this invention. Benzo (b) thiophene-3-Oxime amide acylamino acids, benzo (b) thiophene-3-acetamide acylamino acid derivatives and benzo (b) thiophene-3-amide acylamino acid derivatives: Acylamino acid derivatives of the benzo (b) thiophene oxime amides, benzo (b) thiophene amides, and benzo (b) thiophene acetamides may be prepared from the corresponding acid such as the compound of formula (14) (scheme 1) by methods previously described for preparing the acylamino acid derivatives. For example the oxime amide of formula 19b (scheme 5) , above may be converted to the corresponding acylamino acid derivative by an amide coupling reaction. Similarly, the benzo (b) thiophene-3- acetamide oxy acid compounds (acetamide derivatives of compound of formula (14) , may be converted to the corresponding N-hydroxyfunctional amide or acylamino acid derivative at the 4-{ or 5- {position of the nucleus as described previously. IV. Methods of Using the Compounds of the Invention: The benzo (b) thiophene compounds described herein are believed to achieve their beneficial therapeutic action principally by direct inhibition of mammalian (including human) SPLA 2 , and not by acting as antagonists for arachidonic acid, nor other active agents below arachidonic acid in the arachidonic acid cascade, such as 5-lipoxygenases, cyclooxygenases, and etc. The method of the invention for inhibiting SP A 2 mediated release of fatty acids comprises contacting mammalian sPLA 2 with a therapeutically effective amount of benzo (b) thiophene compounds corresponding to Formulae (I) or (II) as described herein including salt or a prodrug derivative thereof. Another aspect of this invention is a method for treating Inflammatory Diseases such as inflammatory bowel disease, septic shock, adult respiratory distress syndrome, pancreatitis, trauma, asthma, bronchial asthma, allergic rhinitis, rheumatoid arthritis, osteoarthritis, and related diseases which comprises administering to a mammal (including a human) a therapeutically effective dose of the benzo (b) thiophene compound of the invention (see, formulae I and II) . As previously noted the compounds of this invention are useful for inhibiting SP A 2 mediated release of fatty acids such as arachidonic acid. By the term, "inhibiting" is meant the prevention or therapeutically significant reduction in release of SPLA2 initiated fatty acids by the compounds of the invention. By "pharmaceutically acceptable" it. is meant the carrier, diluent or excipient must be compatible with the other ingredients of the formulation and not deleterious to the recipient thereof. The specific dose of a compound administered according to this invention to obtain therapeutic or prophylactic effects will, of course, be determined by the particular circumstances surrounding the case, including, for example, the compound administered, the route of administration and the condition being treated. Typical daily doses will contain a non-toxic dosage level of from about 0.01 mg/kg to about 50 mg/kg of body weight of an active compound of this invention. Preferably compounds of the invention (per Formula (I) or (II), or (II''), or (II') or (III) or (Illb) or (IV) or (V) or (VI) ) or pharmaceutical formulations containing these compounds are in unit dosage form for administration to a mammal . The unit dosage form can be a capsule or tablet itself, or the appropriate number of any of these. The quantity of Active ingredient in a unit dose of composition may be varied or adjusted from about 0.1 to about 1000 milligrams or more according to the particular treatment involved. It may be appreciated that it may be necessary to make routine variations to the dosage depending on the age and condition of the patient. The dosage will also depend on the route of administration. The compound can be administered by a variety of routes including oral, aerosol, rectal, transdermal, subcutaneous, intravenous, intramuscular, and intranasal. Pharmaceutical formulations of the invention are prepared by combining (e.g., mixing) a therapeutically effective amount of the benzo (b) thiophene compound of the invention together with a pharmaceutically acceptable carrier or diluent therefor. The present pharmaceutical formulations are prepared by known procedures using well- known and readily available ingredients. In making the compositions of the present invention, the Active ingredient will usually be admixed with a carrier, or diluted by a carrier, or enclosed within a carrier which may be in the form of a capsule, sachet, paper or other container. When the carrier serves as a diluent, it may be a solid, semi-solid or liquid material which acts as a vehicle, or can be in the form of tablets, pills, powders, lozenges, elixirs, suspensions, emulsions, solutions, syrups, aerosols (as a solid or in a liquid medium) , or ointment, containing, for example, up to 10% by weight of the active compound. The compounds of the present invention are preferably formulated prior to administration. For the pharmaceutical formulations any suitable carrier known in the art can be used. In such a formulation, the carrier may be a solid, liquid, or mixture of a solid and a liquid. For example, for intravenous injection the compounds of the invention may be dissolved in at a concentration of 2 mg/ml in a 4% dextrose/0.5% Na citrate aqueous solution. Solid form formulations include powders, tablets and capsules. A solid carrier can be one or more substance, which may also act as flavoring agents, lubricants, solubilizers, suspending agents, binders, tablet disintegrating agents and encapsulating material . Tablets for oral administration may contain suitable excipients such as calcium carbonate, sodium carbonate, lactose, calcium phosphate, together with disintegrating agents, such as maize, starch, or alginic acid, and/or binding agents, for example, gelatin or acacia, and lubricating agents such as magnesium stearate, stearic acid, or tale. In powders the carrier is a finely divided solid which is in admixture with the finely divided Active ingredient . In tablets the Active ingredient is mixed with a carrier having the necessary binding properties in suitable proportions and compacted in the shape and size desired. The powders and tablets preferably contain from about 1 to about 99 weight percent of the Active ingredient which is the novel compound of this invention. Suitable solid carriers are magnesium carbonate, magnesium stearate, talc, sugar lactose, pectin, dextrin, starch, gelatin, tragacanth, methyl cellulose, sodium carboxymethyl cellulose, low melting waxes, and cocoa butter. Sterile liquid form formulations include suspensions, emulsions, syrups and elixirs. The Active ingredient can be dissolved or suspended in a pharmaceutically acceptable carrier, such as sterile water, sterile organic solvent or a mixture of both. The Active ingredient can often be dissolved in a suitable organic solvent, for instance aqueous propylene glycol. Other compositions can be made by dispersing the finely divided Active ingredient in aqueous starch or sodium carboxymethyl cellulose solution or in a suitable oil .

Assay The following chromogenic assay procedure was used to identify and evaluate inhibitors of recombinant human secreted phospholipase A2. The assay described herein has been adapted for high volume screening using 96 well microtiter plates. A general description of this assay method is found in the article, "Analysis of Human Synovial Fluid Phospholipase A2 on Short Chain Phosphatidylcholine-Mixed Micelles: Development of a Spectrophotometric Assay Suitable for a Microtiterplate Reader", by Laure J. Reynolds, Lori L. Hughes, and Edward A Dennis, Analytical Biochemistry, 204, pp. 190-197, 1992 (the disclosure of which is incorporated herein by reference) : Reagents : REACTION BUFFER - CaCl 2 -2H 2 0 (1.47 g/L) KC1 (7.455 g/L) Bovine Serum Albumin (fatty acid free) (1 g/L) (Sigma A-7030, product of Sigma Chemical Co., St. Louis MO, USA) TRIS HCl (3.94 g/L) pH 7.5 (adjust with NaOH) ENZYME BUFFER - 0.05 NaOAc.3H 2 0, pH 4.5 0.2 NaCl Adjust pH to 4.5 with acetic acid DTNB - 5, 5 ' -dithiobis-2-nitrobenzoic acid RACEMIC DIHEPTANOYL THIO - PC racemic 1,2-bis (heptanoylthio) -1, 2-dideoxy-sn- glycero-3-phosphorylcholine TRITON X-100™ prepare at 6.249 ; mg/ml in reaction buffer to equal lOuM. REACTION MIXTURE - A measured volume of racemic dipheptanoyl thio PC supplied in chloroform at a concentration of 100 mg/ml is taken to dryness and redissolved in 10 millimolar TRITON X-100™ nonionic detergent aqueous solution. Reaction Buffer is added to the solution, then DTNB to give the Reaction Mixture. The reaction mixture thus obtained contains ImM diheptanoly thio-PC substrate, 0.29 mm Triton X-100™ detergent, and 0.12 mm DTMB in a buffered aqueous solution at pH 7.5. Assay Procedure : 1. Add 0.2 ml reaction mixture to all wells; 2. Add 10 ul test compound (or solvent blank) to appropriate wells, mix 20 seconds; 3. Add 50 nanograms of SPLA 2 (10 microliters) to appropriate wells; 4. Incubate plate at 40 °C for 30 minutes; 5. Read absorbance of wells at 405 nanometers with an automatic plate reader. Tests were done in triplicate. Typically, compounds were tested at a final concentration of- 5 ug/ml . Compounds were considered active when they exhibited 40% inhibition or greater compared to uninhibited control reactions when measured at 405 nanometers. Lack of color development at 405 nanometers evidenced inhibition. Compounds initially found to be active were re-assayed to confirm their activity and, if sufficiently active, IC5 0 values were determined. Typically, the IC5 0 values (see, Table I, below) were determined by diluting test compound serially two-fold such that the final concentration in the reaction ranged from 45 ug/mL to 0.35 ug/ml . More potent inhibitors required significantly greater dilution. In all cases, % inhibition measured at 405 nanometers generated by enzyme reactions containing inhibitors relative to the uninhibited control reactions was determined. Each sample was titrated in triplicate and result values were averaged for plotting and calculation of IC5 0 values. IC5 0 values were determined by plotting log concentration versus inhibition values in the range from 10-90% inhibition.
