## Background
Interleukin-1 (IL-1) and Tumor Necrosis Factor .alpha. (TNF-.alpha.) are pro-inflammatory cytokines secreted by a variety of cells, including monocytes and macrophages, in response to many inflammatory stimuli (e.g., lipopolysaccharide--LPS) or external cellular stress (e.g., osmotic shock and peroxide).

Elevated levels of TNF-.alpha. and/or IL-1 over basal levels have been implicated in mediating or exacerbating a number of disease states including rheumatoid arthritis; Pagets disease; osteophorosis; multiple myeloma; uveititis; acute and chronic myelogenous leukemia; pancreatic .beta. cell destruction; osteoarthritis; rheumatoid spondylitis; gouty arthritis; inflammatory bowel disease; adult respiratory distress syndrome (ARDS); psoriasis; Crohn's disease; allergic rhinitis; ulcerative colitis; anaphylaxis; contact dermatitis; asthma; muscle degeneration; cachexia; Reiter's syndrome; type I and type II diabetes; bone resorption diseases; graft vs. host reaction; ischemia reperfusion injury; atherosclerosis; brain trauma; multiple sclerosis; cerebral malaria; sepsis; septic shock; toxic shock syndrome; fever, and myalgias due to infection. HIV-1, HIV-2, HIV-3, cytomegalovirus (CMV), influenza, adenovirus, the herpes viruses (including HSV-1, HSV-2), and herpes zoster are also exacerbated by TNF-.alpha..

It has been reported that TNF-.alpha. plays a role in head trauma, stroke, and ischemia. For instance, in animal models of head trauma (rat), TNF-.alpha. levels increased in the contused hemisphere (Shohami et al., J. Cereb. Blood Flow Metab. 14, 615 (1994)). In a rat model of ischemia wherein the middle cerebral artery was occluded, the levels of TNF-.alpha. mRNA of TNF-.alpha. increased (Feurstein et al., Neurosci. Lett. 164, 125 (1993)). Administration of TNF-.alpha. into the rat cortex has been reported to result in significant neutrophil accumulation in capillaries and adherence in small blood vessels. TNF-.alpha. promotes the infiltration of other cytokines (IL-1.beta., IL-6) and also chemokines, which promote neutrophil infiltration into the infarct area (Feurstein, Stroke 25, 1481 (1994)). TNF-.alpha. has also been implicated to play a role in type II diabetes (Endocrinol. 130, 43-52, 1994; and Endocrinol. 136, 1474-1481, 1995).

TNF-.alpha. appears to play a role in promoting certain viral life cycles and disease states associated with them. For instance, TNF-.alpha. secreted by monocytes induced elevated levels of HIV expression in a chronically infected T cell clone (Clouse et al., J. Immunol. 142, 431 (1989)). Lahdevirta et al., (Am. J. Med. 85, 289 (1988)) discussed the role of TNF-.alpha. in the HIV associated states of cachexia and muscle degradation.

TNF-.alpha. is upstream in the cytokine cascade of inflammation. As a result, elevated levels of TNF-.alpha. may lead to elevated levels of other inflammatory and proinflammatory cytokines, such as IL-1, IL-6, and IL-8.

Elevated levels of IL-1 over basal levels have been implicated in mediating or exacerbating a number of disease states including rheumatoid arthritis; osteoarthritis; rheumatoid spondylitis; gouty arthritis; inflammatory bowel disease; adult respiratory distress syndrome (ARDS); psoriasis; Crohn's disease; ulcerative colitis; anaphylaxis; muscle degeneration; cachexia; Reiter's syndrome; type I and type II diabetes; bone resorption diseases; ischemia reperfusion injury; atherosclerosis; brain trauma; multiple sclerosis; sepsis; septic shock; and toxic shock syndrome. Viruses sensitive to TNF-.alpha. inhibition, e.g., HIV-1, HIV-2, HIV-3, are also affected by IL-1.

TNF-.alpha. and IL-1 appear to play a role in pancreatic .beta. cell destruction and diabetes. Pancreatic .beta. cells produce insulin which helps mediate blood glucose homeostasis. Deterioration of pancreatic .beta. cells often accompanies type I diabetes. Pancreatic .beta. cell functional abnormalities may occur in patients with type II diabetes. Type II diabetes is characterized by a functional resistance to insulin. Further, type II diabetes is also often accompanied by elevated levels of plasma glucagon and increased rates of hepatic glucose production. Glucagon is a regulatory hormone that attenuates liver gluconeogenesis inhibition by insulin. Glucagon receptors have been found in the liver, kidney and adipose tissue. Thus glucagon antagonists are useful for attenuating plasma glucose levels (WO 97/16442, incorporated herein by reference in its entirety). By antagonizing the glucagon receptors, it is thought that insulin responsiveness in the liver will improve, thereby decreasing gluconeogenesis and lowering the rate of hepatic glucose production.

In rheumatoid arthritis models in animals, multiple intra-articular injections of IL-1 have led to an acute and destructive form of arthritis (Chandrasekhar et al., Clinical Immunol Immunopathol. 55, 382 (1990)). In studies using cultured rheumatoid synovial cells, IL-1 is a more potent inducer of stromelysin than is TNF-.alpha. (Firestein, Am. J. Pathol. 140, 1309 (1992)). At sites of local injection, neutrophil, lymphocyte, and monocyte emigration has been observed. The emigration is attributed to the induction of chemokines (e.g., IL-8), and the up-regulation of adhesion molecules (Dinarello, Eur. Cytokine Netw. 5, 517-531 (1994)).

IL-1 also appears to play a role in promoting certain viral life cycles. For example, cytokine-induced increase of HIV expression in a chronically infected macrophage line has been associated with a concomitant and selective increase in IL-1 production (Folks et al., J. Immunol. 136, 40 (1986)). Beutler et al. (J. Immunol. 135, 3969 (1985)) discussed the role of IL-1 in cachexia. Baracos et al. (New Eng. J. Med. 308, 553 (1983)) discussed the role of IL-1 in muscle degeneration.

In rheumatoid arthritis, both IL-1 and TNF-.alpha. induce synoviocytes and chondrocytes to produce collagenase and neutral proteases, which leads to tissue destruction within the arthritic joints. In a model of arthritis (collagen-induced arthritis (CIA) in rats and mice), intra-articular administration of TNF-.alpha. either prior to or after the induction of CIA led to an accelerated onset of arthritis and a more severe course of the disease (Brahn et al., Lymphokine Cytokine Res. 11, 253 (1992); and Cooper, Clin. Exp. Immunol. 898, 244 (1992)).

IL-8 has been implicated in exacerbating and/or causing many disease states in which massive neutrophil infiltration into sites of inflammation or injury (e.g., ischemia) is mediated by the chemotactic nature of IL-8, including, but not limited to, the following: asthma, inflammatory bowel disease, psoriasis, adult respiratory distress syndrome, cardiac and renal reperfusion injury, thrombosis and glomerulonephritis. In addition to the chemotaxis effect on neutrophils, IL-8 also has the ability to activate neutrophils. Thus, reduction in IL-8 levels may lead to diminished neutrophil infiltration.

Several approaches have been taken to block the effect of TNF-.alpha.. One approach involves using soluble receptors for TNF-.alpha. (e.g., TNFR-55 or TNFR-75), which have demonstrated efficacy in animal models of TNF-.alpha.-mediated disease states. A second approach to neutralizing TNF-.alpha. using a monoclonal antibody specific to TNF-.alpha., cA2, has demonstrated improvement in swollen joint count in a Phase II human trial of rheumatoid arthritis (Feldmann et al., Immunological Reviews, pp. 195-223 (1995)). These approaches block the effects of TNF-.alpha. and IL-1 by either protein sequestration or receptor antagonism.

The "pharmacologically acceptable salts" include basic salts of inorganic and organic acids, including but not limited to hydrochloric acid, hydrobromic acid, sulphuric acid, phosphoric acid, methanesulphonic acid, ethanesulfonic acid, malic acid, acetic acid, oxalic acid, tartaric acid, citric acid, lactic acid, fumaric acid, succinic acid, maleic acid, salicylic acid, benzoic acid, phenylacetic acid, mandelic acid and the like. When compounds of the invention include an acidic function such as a carboxy group, then suitable pharmaceutically acceptable cation pairs for the carboxy group are well known to those skilled in the-art and include alkaline, alkaline earth, ammonium, quaternary ammonium cations and the like. For additional examples of "pharmacologically acceptable salts," see infra and Berge et al, J. Pharm.

(tumor necrosis factor-.alpha.). disease states wherein TNF, IL-1, IL-6, and/or IL-8 plays a role, either.-directly as TNF, IL-1, IL-6, and/or IL-8 itself, or by TNF, IL-1, IL-6, and/or IL-8 inducing another cytokine to be released. For example, a disease state in which IL-1 plays a major role, but in which the production of or action of IL-1 is a result of TNF, would be considered mediated by TNF. nucleophile, such as an amine, a thiol or an alcohol nucleophile. Such leaving groups are well known in the art. Examples of such leaving groups include, but are not limited to, N-hydroxysuccinimide, N-hydroxybenzotriazole, halides, triflates, tosylates and the like. Preferred leaving groups are indicated herein where appropriate. are used to prevent selected reactive groups, such as carboxy, amino, hydroxy, mercapto and the like, from undergoing undesired reactions, such as nucleophilic, electrophilic, oxidation, reduction and the like. Preferred protecting groups are indicated herein where appropriate. Examples of amino protecting groups include, but are not limited to, aralkyl, substituted aralkyl, cycloalkenylalkyl and substituted cycloalkenyl alkyl, allyl, substituted allyl, acyl, alkoxycarbonyl, aralkoxycarbonyl, silyl and the like. Examples of aralkyl include, but are not limited to, benzyl, ortho-methylbenzyl, trityl and benzhydryl, which can be optionally substituted with halogen, alkyl, alkoxy, hydroxy, nitro, acylamino, acyl and the like, and salts, such as phosphonium and ammonium salts. Examples of aryl groups include phenyl, naphthyl, indanyl, anthracenyl, 9-(9-phenylfluorenyl), phenanthrenyl, durenyl and the like. Examples of cycloalkenylalkyl or substituted cycloalkylenylalkyl radicals, preferably have 6-10 carbon atoms, include, but are not limited to, cyclohexenyl methyl and the like. Suitable acyl, alkoxycarbonyl and aralkoxycarbonyl groups include benzyloxycarbonyl, t-butoxycarbonyl, iso-butoxycarbonyl, benzoyl, substituted benzoyl, butyryl, acetyl, tri-fluoroacetyl, tri-chloro acetyl, phthaloyl and the like. A mixture of protecting groups can be used to protect the same amino group, such as a primary amino group can be protected by both an aralkyl group and an aralkoxycarbonyl group. Amino protecting groups can also form a heterocyclic ring with the nitrogen to which they are attached, for example, 1,2-bis(methylene)benzene, phthalimidyl, succinimidyl, maleimidyl and the like and where these heterocyclic groups can further include adjoining aryl and cycloalkyl rings. In addition, the heterocyclic groups can be mono-, di- or tri-substituted, such as nitrophthalimidyl. Amino groups may also be protected against undesired reactions, such as oxidation, through the formation of an addition salt, such as hydrochloride, toluenesulfonic acid, trifluoroacetic acid and the like. Many of the amino protecting groups are also suitable for protecting carboxy, hydroxy and mercapto groups. For example, aralkyl groups. Alkyl groups are also sutiable groups for protecting hydroxy and mercapto groups, such as tert-butyl.

Silyl protecting groups are silicon atoms optionally substituted by one or more alkyl, aryl and aralkyl groups. Suitable silyl protecting groups include, but are not limited to, trimethylsilyl, triethylsilyl, tri-isopropylsilyl, tert-butyldimethylsilyl, dimethylphenylsilyl, 1,2-bis(dimethylsilyl)benzene, 1,2-bis(dimethylsilyl)ethane and diphenylmethylsilyl. Silylation of an amino groups provide mono- or di-silylamino groups. Silylation of aminoalcohol compounds can lead to a N,N,O-tri-silyl derivative. Removal of the silyl function from a silyl ether function is readily accomplished by treatment with, for example, a metal hydroxide or ammonium flouride reagent, either as a discrete reaction step or in situ during a reaction with the alcohol group. Suitable silylating agents are, for example, trimethylsilyl chloride, tert-buty-dimethylsilyl chloride, phenyldimethylsilyl chloride, diphenylmethyl silyl chloride or their combination products with imidazole or DMF. Methods for silylation of amines and removal of silyl protecting groups are well known to those skilled in the art. Methods of preparation of these amine derivatives from corresponding amino acids, amino acid amides or amino acid esters are also well known to those skilled in the art of organic chemistry including amino acid/amino acid ester or aminoalcohol chemistry.

Protecting groups are removed under conditions which will not affect the remaining portion of the molecule. These methods are well known in the art and include acid hydrolysis, hydrogenolysis and the like. A preferred method involves removal of a protecting group, such as removal of a benzyloxycarbonyl group by hydrogenolysis utilizing palladium on carbon in a suitable solvent system such as an alcohol, acetic acid, and the like or mixtures thereof. A t-butoxycarbonyl protecting group can be removed utilizing an inorganic or organic acid, such as HCl or trifluoroacetic acid, in a suitable solvent system, such as dioxane or methylene chloride. The resulting amino salt can readily be neutralized to yield the free amine. Carboxy protecting group, such as methyl, ethyl, benzyl, tert-butyl, 4-methoxyphenylmethyl and the like, can be removed under hydroylsis and hydrogenolysis conditions well known to those skilled in the art.

Prodrugs of the compounds of this invention are also contemplated by this invention. A prodrug is an active or inactive compound that is modified chemically through in vivo physicological action, such as hydrolysis, metabolism and the like, into a compound of this invention following adminstration of the prodrug to a patient. The suitability and techniques involved in making and using prodrugs are well known by those skilled in the art. For a general discussion of prodrugs involving esters see Svensson and Tunek Drug Metabolism Reviews 165 (1988) and Bundgaard Design of Prodrugs, Elsevier (1985). Examples of a masked carboxylate anion include a variety of esters, such as alkyl (for example, methyl, ethyl), cycloalkyl (for example, cyclohexyl), aralkyl (for example, benzyl, p-methoxybenzyl), and alkylcarbonyloxyalkyl (for example, pivaloyloxymethyl). Amines have been masked as arylcarbonyloxymethyl substituted derivatives which are cleaved by esterases in vivo releasing the free drug and formaldehyde (Bungaard J. Med. Chem. 2503 (1989)). Also, drugs containing an acidic NH group, such as imidazole, imide, indole and the like, have been masked with N-acyloxymethyl groups (Bundgaard Design of Prodrugs, Elsevier (1985)). Hydroxy groups have been masked as esters and ethers. EP 039,051 (Sloan and Little, Apr. 11, 1981) discloses Mannich-base hydroxamic acid prodrugs, their preparation and use.

Compounds according to the invention can be synthesized according to one or more of the following methods. It should be noted that the general procedures are shown as it relates to preparation of compounds having unspecified stereochemistry. However, such procedures are generally applicable to those compounds of a specific stereochemistry, e.g., where the stereochemistry about a group is (S) or (R). In addition, the compounds having one stereochemistry (e.g., (R)) can often be utilized to produce those having opposite stereochemistry (i.e., (S)) using well-known methods, for example, by inversion.

4(3H) -Pyrimidinones:

For the synthesis of 4(3H)-pyrimidinones II (or its tautomer, 4-hydroxy-pyrimidines), the approach displayed in Scheme 1 may be followed (for a review of synthetic methods see: D. J. Brown, Heterocyclic Compounds: the Pyrimidines, supra). This approach involves the cyclization reaction between an acrylic acid ester XII and an amidine V followed by oxidation of the resulting dihydropyrimidinone XIII to give II. ##STR14##

For the synthesis of 2-substituted 5-(4-fluorophenyl)-6-(4-pyridyl)-4-hydroxy-pyrimidines II (Scheme 2), the disubstituted acrylic acid ester XII may be prepared conveniently by condensation of pyridine-4-carboxaldehyde with 4-fluorophenylacetic acid followed by esterification. XII may be reacted with a variety of amidines V at elevated temperature. As a dehydrogenating agent for the conversion of XIII to II, sodium nitrite/acetic acid is suitable. ##STR15##

Accordingly, further compounds of formula II may be obtained in which R.sup.12 is any other heteroaryl ring within the definition of R.sup.12 by the appropriate choice of starting material. Such starting materials include but are not limited to .sup.2 -methylpyridine-4-carboxaldehyde, 2,6-dimethylpyridine-4-carboxaldehyde (Mathes and Sauermilch, Chem. Ber. 88, 1276-1283 (1955)), quinoline-4-carboxaldehyde, pyrimidine-4-carboxaldehyde, 6-methylpyrimidine-4-carbox-aldehyde, 2-methylpyrimidine-4-carboxaldehyde, 2,6-dimethylpyrimidine-4-carboxaldehyde (Bredereck et al., Chem. Ber. 97, 3407-3417 (1964)). The use of 2-nitropyridine-4-carboxaldehyde would lead to a derivative of formula II with R.sup.12 represented by a 2-nitro-4-pyridyl group. Catalytic reduction of the nitro to an amino group would provide the 2-amino-4-pyridyl derivative of II. The approach displayed in Scheme 2 is applicable to the use of other aryl acetic acids leading to compounds of formula II with different aryl groups as R.sup.11.

Pyrimidinone II (R.sup.1 =H) may be substituted at the N-3 position by reaction with e.g. an alkyl halide, such as methyl iodide or ethyl bromide in the presence of an appropriate base such as potassium carbonate and the like. ##STR16##

Another approach (Scheme 3) leading to 5,6-diaryl-4-hydroxy-pyrimidines involves the cyclization of the b-keto ester XIV with thiourea to give the thiouracil derivative XV. XV can be S-monomethylated to XVI. Reaction of XVI with primary and secondary amines leads to 2-amino substituted 4-hydroxy-pyrimidines II. Further 2-thioether derivatives of II with R.sup.1 =SR.sup.21 can be obtained, for example by alkylation of XV with alkyl halides. Treatment of XV or XVI with Raney nickel and H.sub.2 provides compounds of structure II wherein R.sup.1 is H.

Although Scheme 3 illustrates syntheses in which R.sup.12 is 4-pyridyl, this approach may be equally applied to any other heteroaryl ring within the definition of R.sup.12 by the appropriate choice of the starting material. Such starting materials include but are not limited to ethyl 2-methyl isonicotinate (Efimovsky and Rumpf, Bull. Soc. Chim. FR. 648-649 (1954)), methyl pyrimidine-4-carboxylate, methyl 2-methylpyrimidine-4-carboxylate, methyl 6-methylpyrimidine-4-carboxylate and methyl 2,6-dimethylpyrimidine-4-carboxylate (Sakasi et al., Heterocycles 13, 235 (1978)). Likewise, methyl 2-nitroisonicotinate (Stanonis, J. Org. Chem. 22, 475 (1957)) may be reacted with an aryl acetic acid ester followed by cyclization of the resultant b-keto ester with thiourea analogously to Scheme 3. Subsequent catalytic reduction of the nitro group to an amino group would give a pyrimidinone II in which R.sub.12 is represented by a 2-amino-4-pyridyl group (Scheme 4). ##STR17##

Furthermore, methyl 2-acetamido isonicotinate (Scheme 5) may be reacted analogously to Scheme 3 after appropriate protection of the amide nitrogen with e.g. a tert-butyldimethylsilyloxymethyl group (Benneche et al., Acta Chem. Scand. B 42 384-389 (1988)), a tert-butyldimethylsilyl group, a benzyloxymethyl group, a benzyl group or the like (P.sub.1). ##STR18##

Removal of the protecting group P.sub.1 of the resulting pyrimidine II with a suitable reagent (e.g., tetrabutylammonium fluoride in the case where P.sub.1 is t-butyldimethyl-silyloxymethyl) would then lead to a pyrimidinone II with R.sup.12 represented by a 2-acetamido-4-pyridyl group. Needless to say, ethyl p-fluorophenyl acetate may be substituted by any alkyl arylacetate in the procedure illustrated in Scheme 3 thus providing compounds of formula II with different R.sup.11 aryl substituents.

In a further process, pyrimidinones II may be prepared by coupling a suitable derivative of XVIII (L is a leaving group, such as halogen radical and the like) with an appropriate aryl equivalent. ##STR19##

Such aryl/heteroaryl couplings are well known to those skilled in the art and involve an organic-metallic component for reaction with a reactive derivative, e.g., a halogeno derivative, of the second compound in the presence of a catalyst. The metallo-organic species may be provided either by the pyrimidinone in which case the aryl component provides the reactive halogen equivalent or the pyrimidinone may be in the form of a reactive 5-halogeno derivative for reaction with a metallo organic aryl compound. Accordingly, 5-bromo and 5-iodo derivatives of XVIII (L.dbd.Br, I) may be treated with arylalkyl tin compounds, e.g., trimethylstannylbenzene, in an inert solvent such as tetrahydrofuran in the presence of a palladium catalyst, such as di(triphenylphosphine)palladium(II)dichloride. (Peters et al., J. Heterocyclic Chem. 27, 2165-2173, (1990). Alternatively, the halogen derivative of XVIII may be converted into a trialkyltin derivative (L.dbd.Bu.sub.3 Sn) by reaction with e.g. tributylstannyl chloride following lithiation with butyllithium and may then be reacted with an aryl halide in the presence of a catalyst. (Sandosham and Undheim, Acta Chem. Scand. 43, 684-689 (1989). Both approaches would lead to pyrimidines II in which R.sup.11 is represented by aryl and heteroaryl groups.

As reported in the literature (Kabbe, Lieb. Ann. Chem. 704, 144 (1967); German Patent 1271116 (1968)) and displayed in Scheme 6, 5-aryl-2,6-dipyridyl-4(3 H)-pyrimidinones II may be prepared in a one step synthesis by reaction of the cyanopyridine with an arylacetyl ester, such as ethyl phenylacetate in the presence of sodium methoxide. ##STR20##

In Scheme 7, compounds of the present invention of formula XXX can be readily prepared by reacting the methylthio intermediate XXXI with the amine NHR.sup.5 R.sup.21, for example by heating the mixture preferably at a temperature greater than 100.degree. C., more preferably 150-210.degree. C. Alternatively, compounds of formula XXX can be readily prepared by reacting the methylsulfonyl intermediate XXXII with the amine NHR.sup.5 R.sup.21, for example by heating the mixture preferably at a temperature greater than 40.degree. C., more preferably 50-210.degree. C. ##STR21##

Amines of formula NHR.sup.5 R.sup.21 are commercially available or can be readily prepared by those skilled in the art from commercially available starting materials. For example, an amide, nitro or cyano group can be reduced under reducing conditions, such as in the presence of a reducing agent like lithium aluminum hydride and the like, to form the corresponding amine. Alkylation and acylation of amino groups are well known in the art. Chiral and achiral substituted amines can be prepared from chiral amino acids and amino acid amides (for example, alkyl, aryl, heteroaryl, cycloalkyl, arylalkyl, heteroarylalkyl, cycloalkylalkyl and the like substituted glycine, .beta.-alanine and the like) using methods well known in the art, such as H. Brunner, P. Hankofer, U. Holzinger, B. Treittinger and H. Schoenenberger, Eur. J. Med. Chem. 25, 35-44, 1990; M. Freiberger and R. B. Hasbrouck, J. Am. Chem. Soc. 82, 696-698, 1960; Dornow and Fust, Chem. Ber. 87, 984, 1954; M. Kojima and J. Fujita, Bull. Chem. Soc. Jpn. 55, 1454-1459, 1982; W. Wheeler and D. O'Bannon, Journal of Labelled Compounds and Radiopharmaceuticals XXXI, 306, 1992; and S. Davies, N. Garrido, O. Ichihara and I. Walters, J. Chem. Soc., Chem. Commun. 1153, 1993.

Pyridones:

As displayed in Scheme 8, a suitable route to 2(1 H)-pyridones III involves the cyclization reaction between an a,b-unsaturated ketone XXII and a sufficiently reactive, substituted acetamide in the presence of base (El-Rayyes and Al-Hajjar, J. Heterocycl. Chem. 21, 1473 (1984)) and subsequent dehydrogenation. ##STR22##

Accordingly (Scheme 9), pyridine-4-carboxaldehyde or other heteroaromatic carboxaldehyde-like pyrimidine-4-carboxaldehydes or quinoline-4-carboxyaldehydes may be reacted with acetyl aryl, acetyl heteroaryl or acetyl cycloalkyl derivatives in the presence of piperidine/acetic acid at elevated temperature (Bayer and Hartmann, Arch. Pharm. (Weinheim) 324, 815 (1991)) as well as pinacolone (CH.sub.3 --CO--C(CH.sub.3).sub.3) in the presence of sodium hydroxide to provide the unsaturated ketone XXII (or the analogous ketone from the corresponding heteroaromatic-4-carboxyaldehyde). The reaction of XXII with phenylacetamide in the presence of sodium ethoxide then may lead via the 3,4-dihydropyridone to 6-substituted 3-phenyl-4-(heteroaryl)-2(1 H)-pyridones of structure III.

In Scheme 10, a feasible route is illustrated leading to 6-chloro-2(1 H)-pyridone XXIV, a versatile intermediate for further modifications at the 6-position. This approach (G. Simchen, Chem. Ber. 103, 389-397 (1970) is based on the conversion of the unsaturated g-cyanocarboxylic acid chloride XXIII into XXIV in the presence of hydrogen chloride. ##STR23##

Reaction of XXIV with ammonia (Katritzky and Rachwal, J. Heterocylic Chem. 32, 1007 (1995)), primary and secondary amines would lead to 2-amino substituted pyridones III. Furthermore, XXIV may be reacted in a palladium or nickel catalyzed cross-coupling reaction with an alkyl or aryl boronic acid or an alkyl or aryl zinc halide to provide pyridone III wherein R.sup.3 is alkyl or aryl or heteroaryl.

In addition, pyridone III may be substituted at the N-1 position by reaction with, e.g., an alkyl halide in the presence of an appropriate base such as potassium carbonate.

An approach that may lead to a pyrimidinone of the general formula III is illustrated in Scheme 11. ##STR24##

According to this approach (Shaw and Warrener, J. Chem. Soc. 153-156 (1958); Hronowski and Szarek, Can. J. Chem. 63, 2787 (1985); Agathocleous and Shaw, J. Chem. Soc. Perkin Trans. I, 2555 (1993)), an ethoxyacryloyl isothiocyanate XXVI is reacted with a primary amine to give as an addition product the acylthiourea XXVII which can be cyclized under basic or acidic conditions to the thiouracil compound XXVIII. XXVIII may be methylated to the methylthio derivative XXIX, a versatile intermediate for further transformations at the 2-position.

Fused 4(3 H)-Pyrimidinones:

As displayed in Schemes 12 and 13, introduction of a suitable R.sup.4 group through the alkylation of XXXIII affords an intermediate to the fused 5, 6, or 7 membered ring systems of Formula I wherein R.sup.1 and V or W are joined. The synthesis utilizes a haloalkylamine in which the amino group is protected through reaction with 1,2-bis(chlorodimethylsilyl)ethane affording the cyclic stabase derivative (see:Basha and Debernardis Tetrahedron Lett 5271, 1984) which protects the amine in the subsequent alkylation step (sodium hydride, DMF). ##STR25## Deprotection of the amine can be accomplished with acid treatment (p-toluenesulfonic acid) or tetrabutylammonium fluoride treatment. The free amine can then be cyclized in an intramolecular fashion by warming to high temperatures. The bromoalkylamines are either commercially available (eg. 3-bromopropylamine hydrobromide, 2-bromoethylamine hydrobromide) or they can be synthesized from the corresponding haloalkylazide followed by reduction of the azide to the amine (see: Hendry et al Tetrahedron Lett 4597 (1987)). More functionalized haloalkylamines can be used as long as the functional groups are tolerated in the transformations shown in scheme 12 including the bromo derivatives obtained from amino acid precursors as described by Baldwin et al (Synlett. 51-53, 1993) and Leanna et al (Tetrahedron Lett. 4485, 1993).

Alternatively, the fused ring system can be made through the addition of a hydroxyalkylamine as outlined in Scheme 14. Initially, the amine component of the hydroxyalkylamine displaces the 2-methylthio group to afford compound XXXVII which is followed by conversion of the alcohol to a suitable leaving group (eg. methanesulfonate or trifluoromethanesulfonate). Closure of the ring can be accomplished by treatment with an excess of sodium hydride in DMF to afford XXXVI. ##STR26##

The 6,5 fused ring systems can be obtained as outlined in Scheme 15. Alkylation of the N-3 nitrogen with 3-bromo-1-trimethylsilylpropyne can be followed by a displacement of the 2-methylthio group with the appropriate amine component exemplified but not limited to a phenylalkylamine. The 2-amino group under the reaction conditions cyclizes onto the acetylene as shown with a loss of the trimethylsilyl group as well. This transformation is illustrated in the examples below wherein 3-phenyl-1-propylamine and benzylamine are reacted with 3-(3-trimethylsilyl-2-propynyl)-5-(4-fluorophenyl)-2-methylthio-6-(4-pyrid yl)-4(3 H)-pyrimidinone to afford the corresponding 6, 5 fused system. ##STR27##

Compounds of the invention when U is CHR.sub.21 can be prepared according to Scheme 2 above wherein R1 contains an leaving group or a group which can be converted into a leaving group (L*) which can be reacted with a primidine nitrogen atoms to form the fused ring (see Scheme 16).

The following Examples are presented for illustrative purposes only and are not intended, nor should they be construed, as limiting the invention in any manner. Those skilled in the art will appreciate that modifications and variations of the compounds disclosed herein can be made without violating the spirit or scope of the present invention.

General procedure for the preparation of 2-substituted 5-(4-fluorophenyl)-6-(4-pyridyl)-4(3 H)-pyrimidones ##STR28## a. 2-(4-Fluorophenyl)-3-(4-pyridyl)-acrylic acid: A mixture of 4-fluorophenylacetic acid (9 g, 58.4 mmol), 4-pyridinecarboxaldehyde (5.6 ml, 58.6 mmol), pyridine (6 ml) and acetic anhydride (6 ml) was heated at 150.degree. C. for 1 h followed by evaporation and co-distillation with water. The resulting material crystallized on addition of ethanol. The solids were filtered and washed with ethanol and ethyl acetate to provide the title compound. MS (m/z): 244.0 (M+H).sup.+ ; C.sub.14 H.sub.10 FNO.sub.2 requir. 243.2 .sup.1 H-NMR (DMSO-d.sub.6): d 8.43, 6.98 (2d, each 2 H, Pyrid.), 7.73 (s, 1 H, CH.dbd.), 7.21 (d, 4 H, PhF).

b. Ethyl 2-(4-fluorophenyl)-3-(4-pyridyl)-acrylate: Conc. sulfuric acid (2.2 ml) was added carefully to a suspension of 2-(4-fluorophenyl)-3-(4-pyridyl)-acrylic acid (6.7 g, 27.5 mmol) in ethanol (120 ml) and the mixture was heated at reflux for 24 h. The solvent was evaporated, the remainder was taken up in dichloromethane and the organic solution was washed with aqueous sodium hydrogencarbonate and water, followed by drying and evaporation. Flash column chromatography on silica gel (hexane-acetone=2:1) provided the pure title compound. MS (m/z): 271.8 (M+H).sup.+ ; C.sub.16 H.sub.14 FNO.sub.2 requir. 271.3 .sup.1 H-NMR (CDCl.sub.3): 8.44, 6.88 (2 m, each 2 H, Pyrid.), 7.72 (s, 1 H, CH.dbd.), 7.16, 7.06 (2m, each 2 H, PhF), 4.28 (q, 2 H, CH.sub.2), 1.28 (t, 3 H, CH.sub.3).

c. General procedure: A stirred mixture of ethyl 2-(4-fluorophenyl)-3-(4-pyridyl)-acrylate (357 mg, 1.38 mmol), the amidine hydrochloride (2.61 mmol) and sodium methoxide (250 mg, 4.62 mmol) in ethanol (5 ml) was heated in a sealed tube at 120.degree. C. for 3 h. It was neutralized with 2N hydrochloric acid prior to evaporation. The residue was taken up in acetic acid (25 ml) and treated with sodium nitrite (670 mg, 9.71 mmol) at 44.degree. C. for 20 min. After evaporation, the resultant product was taken up in dichloromethane and the solution was washed with aqueous sodium hydrogencarbonate and water before drying and evaporation. The product was purified by recrystallization from methanol.

The compounds in table V can be prepared using the appropriate starting materials and the following procedures: The required pyrimidinones with the varied R.sup.11 substituents can be prepared using the general procedures described above. The fused 6, 5 ring system can be prepared as described above affording R.sup.21 as a hydrogen radical. Other R.sup.21 groups can be introduced through a reductive amination process using the corresponding aldehyde with appropriate amino protection (Boc group). For example, N-Boc-phenylalanal can be prepared from the corresponding Weinreb amide through reduction with lithium aluminum hydride as described in the literature (Konieczny and Cushman Tetrahedron Lett 6939, 1992). The N-Boc-phenylalanal can then be reacted with the amino group using sodium triacetoxyborohydride. Alternatively, the alcohol of N-Boc-phenylalanol can be activated under Mitsunobu conditions (triphenylphosphine, diiisopropyl azodicarboxylate) and reacted with the amino group of the 6, 5 fused system followed by removal of the Boc group (trifluoroacetic acid). ______________________________________ ##STR196## R.sub.11          R.sub.21 ______________________________________

Lipopolysaccharide-activated monocyte TNF production assay

Isolation of monocytes

Test compounds were evaluated in vitro for the ability to inhibit the production of TNF by monocytes activated with bacterial lipopolysaccharide (LPS). Fresh residual source leukocytes (a byproduct of plateletpheresis) were obtained from a local blood bank, and peripheral blood mononuclear cells (PBMCs) were isolated by density gradient centrifugation on Ficol-Paque Plus (Pharmacia). PBMCs were suspended at 2.times.10.sup.6 / ml in DMEM supplemented to contain 2% FCS, 10 mM, 0.3 mg/ml glutamate, 100 U/ml penicillin G and 100 mg/ml streptomycin sulfate (complete media). Cells were plated into Falcon flat bottom, 96 well culture plates (200 .mu.l/well) and cultured overnight at 37.degree. C. and 6% CO.sub.2. Non-adherent cells were removed by washing with 200 .mu.l/well of fresh medium. Wells containing adherent cells (.about.70% monocytes) were replenished with 100 .mu.l of fresh medium.

Preparation of test compound stock solutions

Test compounds were dissolved in DMZ. Compound stock solutions were prepared to an initial concentration of 10-50 .mu.M. Stocks were diluted initially to 20-200 .mu.M in complete media. Nine two-fold serial dilutions of each compound were then prepared in complete medium.

Treatment of cells with test compounds and activation of TNF production with lipopolysaccharide

One hundred microliters of each test compound dilution were added to microtiter wells containing adherent monocytes and 100 .mu.l complete medium. Monocytes were cultured with test compounds for 60 min at which time 25 .mu.l of complete medium containing 30 ng/ml lipopolysaccharide from E. coli K532 were added to each well. Cells were cultured an additional 4 hrs. Culture supernatants were then removed and TNF presence in the supernatants was quantified using an ELISA.

Flat bottom, 96 well Corning High Binding ELISA plates were coated overnight (4.degree. C.) with 150 .mu.L/well of 3 .mu.g/ml murine anti-human TNF-.alpha. MAb (R&D Systems #MAB210).

Wells were then blocked for 1 hr at room temperature with 200 .mu.L/well of CaCl.sub.2 -free ELISA buffer supplemented to contain 20 mg/ml BSA (standard ELISA buffer: 20 mM, 150 mM NaCl, 2 mM CaCl.sub.21 0.15 mM thimerosal, pH 7.4). Plates were washed and replenished with 100 .mu.l of test supernatants (diluted 1:3) or standards. Standards consisted of eleven 1.5-fold serial dilutions from a stock of 1 ng/ml recombinant human TNF (R&D Systems). Plates were incubated at room temperature for 1 hr on orbital shaker (300 rpm), washed and replenished with 100 .mu.l/well of 0.5 .mu.g/ml goat anti-human TNF-.alpha. (R&D systems #AB-210-NA) biotinylated at a 4:1 ratio. Plates were incubated for 40 min, washed and replenished with 100 .mu.l/well of alkaline phosphatase-conjugated streptavidin (Jackson ImmunoResearch #016-050-084) at 0.02 .mu.g/ml. Plates were incubated 30 min, washed and replenished with 200 .mu.l/well of 1 mg/ml of p-nitrophenyl phosphate. After 30 min, plates were read at 405 nm on a V.sub.max plate reader.

Data analysis

Standard curve data were fit to a second order polynomial and unknown TNF-.alpha. concentrations determined from their OD by solving this equation for concentration. TNF concentrations were then plotted vs. test compound concentration using a second order polynomial. This equation was then used to calculate the concentration of test compounds causing a 50% reduction in TNF production.

Compounds of the invention can also be shown to inhibit LPS-induced release of IL-1.beta., IL-6 and/or IL-8 from monocytes by measuring concentrations of IL-1.beta., IL-6 and/or IL-8 by methods well known to those skilled in the art. In a similar manner to the above described assay involving the LPS induced release of TNF-.alpha. from monocytes, compounds of this invention can also be shown to inhibit LPS induced release of IL-1.beta., IL-6 and/or IL-8 from monocytes by measuring concentrations of IL-1.beta., IL-6 and/or IL-8 by methods well known to those skilled in the art. Thus, the compounds of the invention may lower elevated levels of TNF-.alpha., IL-1, IL-6, and IL-8 levels. Reducing elevated levels of these inflammatory cytokines to basal levels or below is favorable in controlling, slowing progression, and alleviating many disease states. All of the compounds are useful in the methods of treating disease states in which TNF-.alpha., IL-1.beta., IL-6, and IL-8 play a role to the full extent of the definition of TNF-.alpha.-mediated diseases described herein.

Membrane preparations of CHO/hGLUR cells can be used in place of whole cells at the same assay volume. Final protein concentration of a membrane preparation is determined on a per batch basis.

Assay

The determination of inhibition of glucagon binding can be carried out by measuring the reduction of I.sup.125 -glucagon binding in the presence of compounds of Formula I. The reagents are combined as follows: Compound/     250 .mu.M           CHO/hGLUR Vehicle       Glucagon .sup.125 I-Glucagon Cells ______________________________________ Total Bind- --/5 .mu.l --       25 .mu.l 100 .mu.l ing + Com- 5 .mu.l/-- --       25 .mu.l 100 .mu.l pound Non- --/5 .mu.l 1 .mu.l  25 .mu.l 100 .mu.l specific Binding ______________________________________

The mixture is incubated for 60 min. at 22.degree. C. on a shaker at 275 rpm. The mixture is filtered over pre-soaked (0.5% polyethylimine (PEI)) GF/C filtermat using an 20 Innotech Harvester or Tomtec Harvester with four washes of ice-cold 20mM Tris buffer (pH 7.8). The radioactivity in the filters is determined by a gamma-scintillation counter.

Thus, compounds of the invention may also be shown to inhibit the binding of glucagon to glucagon receptors.

Cyclooxygenase Enzyme Activity Assay

The human monocytic leukemia cell line, THP-1, differentiated by exposure to phorbol esters expresses only COX-1; the human osteosarcoma cell line 143B expresses predominantly COX-2. THP-1 cells are routinely cultured in RPMI complete media supplemented with 10% FBS and human osteosarcoma cells (HOSC) are cultured in minimal essential media supplemented with 10% fetal bovine serum (MEM-10% FBS); all cell incubations are at 37.degree. C. in a humidified environment containing 5% CO.sub.2.

COX-1 Assay

In preparation for the COX-1 assay, THP-1 cells are grown to confluency, split 1:3 into RPMI containing 2% FBS and 10 mM phorbol 12-myristate 13-acetate (TPA), and incubated for 48 hours on a shaker to prevent attachment. Cells are pelleted and resuspended in Hank's Buffered Saline (HBS) at a concentration of 2.5.times.10.sup.6 cells/mL and plated in 96-well culture plates at a density of 5.times.10 cells/mL. Test compounds are diluted in HBS and added to the desired final concentration and the cells are incubated for an additional 4 hours. Arachidonic acid is added to a final concentration of 30 mM, the cells incubated for 20 minutes at 37.degree. C., and enzyme activity determined as described below.

COX-2 Assay

For the COX-2 assay, subconfluent HOSC are trypsinized and resuspended at 3.times.10.sup.6 cells/mL in MEM-FBS containing 1 ng human IL-lb/mL, plated in 96-well tissue culture plates at a density of 3.times.10.sup.6 cells per well, incubated on a shaker for 1 hour to evenly distribute cells, followed by an additional 2 hour static incubation to allow attachment. The media is then replaced with MEM containing 2% FBS (MEM-2% FBS) and 1 ng human IL-lb/mL, and the cells incubated for 18-22 hours. Following replacement of media with 190 mL MEM, 10 mL of test compound diluted in HBS is added to achieve the desired concentration and the cells incubated for 4 hours. The supernatants are removed and replaced with MEM containing 30 mM arachidonic acid, the cells incubated for 20 minutes at 37.degree. C., and enzyme activity determined as described below.

COX Activity Determined

After incubation with arachidonic acid, the reactions are stopped by the addition of 1 N HCl, followed by neutralization with 1 N NaOH and centrifugation to pellet cell debris. Cyclooxygenase enzyme activity in both HOSC and THP-1 cell supernatants is determined by measuring the concentration of PGE.sub.2 using a commercially available ELISA (Neogen #404110). A standard curve of PGE.sub.2 is used for calibration, and commercially available COX-1 and COX-2 inhibitors are included as standard controls.

The daily parenteral dosage regimen will be from about 0.1 to about 30 mg/kg of total body weight, preferably from about 0.1 to about 10 mg/kg, and more preferably from about 0.25 mg to 1 mg/kg.

Injectable preparations, such as sterile injectable aqueous or oleaginous suspensions, may be formulated according to the known are using suitable dispersing or wetting agents and suspending agents. The sterile injectable preparation may also be a sterile injectable solution or suspension in a non-toxic parenterally acceptable diluent or solvent, for example as a solution in 1,3-butanediol. Among the acceptable vehicles and solvents that may be employed are water, Ringer's solution, and isotonic sodium chloride solution. In addition, sterile, fixed oils are conventionally employed as a solvent or suspending medium. For this purpose any bland fixed oil may be employed, including synthetic mono- or diglycerides. In addition, fatty acids such as oleic acid find use in the preparation of injectables.

Suppositories for rectal administration of the drug can be prepared by mixing the drug with a suitable non-irritating excipient such as cocoa butter and polyethylene glycols that are solid at ordinary temperatures but liquid at the rectal temperature and will therefore melt in the rectum and release the drug.

A suitable topical dose of active ingredient of a compound of the invention is 0.1 mg to 150 mg administered one to four, preferably one or two times daily. For topical administration, the active ingredient may comprise from 0.001% to 10% w/w, e.g., from 1% to 2% by weight of the formulation, although it may comprise as much as 10% w/w, but preferably not more than 5% w/w, and more preferably from 0.1% to 1% of the formulation.

Formulations suitable for topical administration include liquid or semi-liquid preparations suitable for penetration through the skin (e.g., liniments, lotions, ointments, creams, or pastes) and drops suitable for administration to the eye, ear, or nose.

For administration, the compounds of this invention are ordinarily combined with one or more adjuvants appropriate for the indicated route of administration. The compounds may be admixed with lactose, sucrose, starch powder, cellulose esters of alkanoic acids, stearic acid, talc, magnesium stearate, magnesium oxide, sodium and calcium salts of phosphoric and sulphuric acids, acacia, gelatin, sodium alginate, polyvinyl-pyrrolidine, and/or polyvinyl alcohol, and tableted or encapsulated for conventional administration. Alternatively, the compounds of this invention may be dissolved in saline, water, polyethylene glycol, propylene glycol, ethanol, corn oil, peanut oil, cottonseed oil, sesame oil, tragacanth gum, and/or various buffers. Other adjuvants and modes of administration are well known in the pharmaceutical art. The carrier or diluent may include time delay material, such as glyceryl monostearate or glyceryl distearate alone or with a wax, or other materials well known in the art.

The pharmaceutical compositions may be made up in a solid form (including granules, powders or suppositories) or in a liquid form (e.g., solutions, suspensions, or emulsions). The pharmaceutical compositions may be subjected to conventional pharmaceutical operations such as sterilization and/or may contain conventional adjuvants, such as preservatives, stabilizers, wetting agents, emulsifiers, buffers etc.

Solid dosage forms for oral administration may include capsules, tablets, pills, powders, and granules. In such solid dosage forms, the active compound may be admixed with at least one inert diluent such as sucrose, lactose, or starch. Such dosage forms may also comprise, as in normal practice, additional substances other than inert diluents, e.g., lubricating agents such as magnesium stearate. In the case of capsules, tablets, and pills, the dosage forms may also comprise buffering agents. Tablets and pills can additionally be prepared with enteric coatings.

Liquid dosage forms for oral administration may include pharmaceutically acceptable emulsions, solutions, suspensions, syrups, and elixirs containing inert diluents commonly used in the art, such as water. Such compositions may also comprise adjuvants, such as wetting, sweetening, flavoring, and perfuming agents.

Compounds of the present invention can possess one or more asymmetric carbon atoms and are thus capable of existing in the form of optical isomers as well as in the form of racemic or non-racemic mixtures thereof. The optical isomers can be obtained by resolution of the racemic mixtures according to conventional processes, e.g., by formation of diastereoisomeric salts, by treatment with an optically active acid or base. Examples of appropriate acids are tartaric, diacetyltartaric, dibenzoyltartaric, ditoluoyltartaric, and camphorsulfonic acid and then separation of the mixture of diastereoisomers by crystallization followed by liberation of the optically active bases from these salts. A different process for separation of optical isomers involves the use of a chiral chromatography column optimally chosen to maximize the separation of the enantiomers. Still another available method involves synthesis of covalent diastereoisomeric molecules by reacting compounds of the invention with an optically pure acid in an activated form or an optically pure isocyanate. The synthesized diastereoisomers can be separated by conventional means such as chromatography, distillation, crystallization or sublimation, and then hydrolyzed to deliver the enantiomerically pure compound. The optically active compounds of the invention can likewise be obtained by using active starting materials. These isomers may be in the form of a free acid, a free base, an ester or a salt.
