Abstract

Compounds of formulae I and IA which bind VLA-4. Certain of these compounds also inhibit leukocyte adhesion and, in particular, leukocyte adhesion mediated by VLA-4. These compounds are useful in the treatment of inflammatory diseases such as asthma, Alzheimer's disease, atherosclerosis, AIDS dementia, diabetes, inflammatory bowel disease, rheumatoid arthritis, tissue transplantation, tumour metastasis and myocardial ischemia in a mammalian patient. The compounds are also useful for the treatment of inflammatory brain diseases such as multiple sclerosis. Reference has been directed, in pursuance of section 14 of the Patents Act 1953, to specification No. 502580.

VLA-4 contains an a4 chain and a p 1 chain There are at least nine Pi integnns, all sharing the same pi chain and each having a distinct a chain These nine receptors all bind a different complement of the various cell matrix molecules, such as fibronectin, laminin, and collagen. VLA-4, for example, 15 binds to fibronectin. VLA-4 also binds non-matrix molecules that are expressed by endothelial and other cells These non-matrix molecules include VCAM-1, which is expressed on cytokine-activated human umbilical vein endothelial cells in culture. Distinct epitopes of VLA-4 are responsible for the fibronectin and VCAM-1 binding activities and each activity has been shown 20 to be inhibited independently2 Intercellular adhesion mediated by VLA-4 and other cell surface receptors is associated with a number of inflammatory responses. At the site of an injury or other inflammatory stimulus, activated vascular endothelial 25 cells express molecules that are adhesive for leukocytes. The mechanics of leukocyte adhesion to endothelial cells involves, in part, the recognition and binding of cell surface receptors on leukocytes to the corresponding cell surface molecules on endothelial cells. Once bound, the leukocytes migrate across the blood vessel wall to enter the injured site and release chemical 30 mediators to combat infection For reviews of adhesion receptors of the immune system, see, for example, Springer3 and Osbom4. Printed from Mimosa WO 99/06431 „4~ PCT/US98/15313 Inflammatory brain disorders, such as expenmental autoimmune encephalomyelitis (EAE), multiple sclerosis (MS) and meningitis, are examples of central nervous system disorders in which the endothelium/leukocyte adhesion mechanism results m destruction to otherwise 5 healthy brain tissue Large numbers of leukocytes migrate across the blood brain barrier (BBB) in subjects with these inflammatory diseases The leukocytes release toxic mediators that cause extensive tissue damage resulting in impaired nerve conduction and paralysis 10 In other organ systems, tissue damage also occurs via an adhesion mechanism resulting m migration or activation of leukocytes For example, it has been shown that the initial insult following myocardial ischemia to heart tissue can be further complicated by leukocyte entry to the injured tissue causing still further insult (Vedder et al5). Other inflammatory conditions 15 mediated by an adhesion mechanism include, by way of example, asthma6"8, Alzheimer's disease, atherosclerosis9"10, AIDS dementia", diabetes12'14 (including acute juvenile onset diabetis), inflammatory bowel disease15 (including ulcerative colitis and Crohn's disease), multiple sclerosis16"17, rheumatoid arthritis18"21, tissue transplantation22, tumor metastasis23"28, 20 meningitis, encephalitis, stroke, and other cerebral traumas, nephritis, retinitis, atopic dermatitis, psoriasis, myocardial ischemia and acute leukocyte-mediated lung injury such as that which occurs in adult respiratory distress syndrome In view of the above, assays for determining the level VLA-4 in a 25 biological sample containing VLA-4 would be useful, for example, to diagnosis VLA-4 mediated conditions. Additionally, despite these advances in the understanding of leukocyte adhesion, the art has only recently addressed the use of inhibitors of adhesion in the treatment of inflammatory brain diseases and other inflammatory conditions29-30 The present invention 30 addresses these and other needs. Printed from Mimosa WO 99/06431 _5_ PCT/US98/15313 SUMMARY OF THE INVENTION This invention provides compounds which bind to VLA-4.

The isocyanates and thioisocyanates used in this reaction are commercially available or can be prepared from commercially available compounds using well-known synthetic procedures For example, 5 isocyanates and thioisocyanates are readily prepared by reacting the appropnate amine with phosgene or th'ophosgene Examples of isocyanates and thioisocyanates suitable for use in this reaction include, but are not limited to, ethyl isocyanate, n-propyl isocyanate, 4-cyanophenyl isocyanate, 3-methoxyphenyl isocyanate, 2-phenylethyl isocyanate, methyl thioisocyanate, 10 ethyl thioisocyanate, 2-phenylethyl thioisocyanate, 3-phenylpropyl thioisocyanate, 3-(iV,iV-diethylamino)propyl thioisocyanate, phenyl thioisocyanate, benzyl thioisocyanate, 3-pyndyl thioisocyanate, fluorescein isothiocyanate (isomer I) and the like 15 Furthermore, when a compound of formula I or an intermediate thereof contains a primary or secondary amino group, the amino group can be reductively alkylated using aldehydes or ketones to form a secondary or tertiary amino group This reaction is typically conducted by contacting the ammo compound with at least one equivalent, preferably about 1.1 to about 20 1.5 equivalents, of an aldehyde or ketone and at least one equivalent based on the amino compound of a metal hydride reducing agent, such as sodium cyanoborohydride, in an inert diluent, such as methanol, tetrahydrofuran, mixtures thereof and the like, at a temperature ranging from about 0°C to about 50°C for about 1 to about 72 hours. Aldehydes and ketones suitable for 25 use m this reaction include, by way of example, benzaldehyde, 4-chlorobenzaldehyde, valeraldehyde and the like. In a similar manner, when a compound of formula I or an intermediate thereof has a substituent containing a hydroxyl group, the hydroxyl group can 30 be further modified or denvatized either before or after the above coupling reactions to provide, by way of example, ethers, carbamates and the like Compounds having a hydroxyl group on the R5 substituent, for example, can Printed from Mimosa WO 99/06431 - 88 -- PCT/U S98/15313 be prepared using an ammo acid denvative of fonnula VI derived from tyrosine and the like in the above-descnbed reactions. By way of example, a compound of formula I or an intermediate 5 thereof having a substituent containing a hydroxyl group, such as where R5 is a (4-hydroxyphenyl)methyl group, can be readily 0-alkylated to form ethers. This O-alkylation reaction is typically conducted by contacting the hydroxy compound with a suitable alkali or alkaline earth metal base, such as potassium carbonate, in an inert diluent, such as acetone, 2-butanone and the 10 like, to form the alkali or alkaline earth metal salt of the hydroxyl group This salt is generally not isolated, but is reacted in situ with at least one equivalent of an alkyl or substituted alkyl halide or sulfonate, such as an alkyl chloride, bromide, iodide, mesylate or tosylate, to afford the ether. Generally, this reaction is conducted at a temperature ranging from about 60 °C to about 15 150 °C for about 24 to about 72 hours. Preferably, a catalytic amount of sodium or potassium iodide is added to the reaction mixture when an alkyl chlonde or bromide is employed m the reaction. Examples of alkyl or substituted alkyl halides and sulfonates suitable 20 for use in this reaction include, but are not limited to, ferr-butyl bromoacetate, N-tert-butyl chloroacetamide, 1-bromoethylbenzene, ethyl a-bromophenylacetate, 2-(iV-ethyl-A^-phenylamino)ethyl chloride, 2-(NyN-ethylamino)ethyl chloride, 2-(AyV-diisopropylammo)ethyl chlonde, 2-(NJV-dibenzylamino)ethyl chlonde, 3-(Af,N-ethylamino)propyl chlonde, 3-(N-25 benzy]-jV-methylamino)propyl chlonde, N-(2-chloroethyl)morphohne, 2- (hexamethyleneimino)ethyl chlonde, 3-(W-methylpiperazine)propyl chlonde, l-(3-chlorophenyl)-4-(3-chloropropyl)piperazine, 2-(4-hydroxy-4-phenylpiperidine)ethyl chloride, AT-ferf-butyloxycarbonyl-3-pipendinemethyl tosylate, and the like 30 Alternatively, a hydroxyl group present on a substituent of a compound of formula I or an intermediate thereof can be O-alkylating using the Printed from Mimosa WO 99/06431 PCT/US98/15313 .. 89 - Mitsunobu reaction. In this reaction, an alcohol, such as 3-(NtN-dimethylamino)-l-propanol and the like, is reacted with about 1.0 to about 1.3 equivalents of triphenylphosphine and about 1.0 to about 1.3 equivalents of diethyl azodicarboxylate m an inert diluent, such as tetrahydrofuran, at a 5 temperature ranging from about-10°C to about 5°C for about 0 25 to about 1 hour About 1 0 to about 1.3 equivalents of a hydroxy compound, such as N-/er/-butyltyrosme methyl ester, is then added and the reaction mixture is stirred at a temperature of about 0°C to about 30°C for about 2 to about 48 hours to provide the O-alkylated product. 3 In a similar manner, a compound of formula I or an intermediate thereof containing a aryl hydroxy group can be reacted with an aryl iodide to provide a diaryl ether Generally, this reaction is conducted by forming the alkali metal salt of the hydroxyl group using a suitable base, such as sodium 5 hydride, in an inert diluent such as xylenes at a temperature of about -25 °C to about 10°C The salt is then treated with about 1.1 to about 1.5 equivalents of cuprous bromide dimethyl sulfide complex at a temperature ranging from about 10°C to about 30°C for about 0 5 to about 2 0 hours, followed by about 1 1 to about 1 5 equivalents of an aryl iodide, such as sodium 2-iodobenzoate ) and the like The reaction is then heated to about 70°C to about 150°C for about 2 to about 24 hours to provide the diaryl ether Additionally, a hydroxy-containing compound can also be readily derivatized to form a carbamate In one method for prepanng such 5 carbamates, a hydroxy compound of formula I or an intermediate thereof is contacted with about 1 0 to about 1 2 equivalents of 4-nitrophenyl chloroformate in an inert diluent, such as dichloromethane, at a temperature ranging from about -25 °C to about 0°C for about 0.5 to about 2 0 hours. Treatment of the resulting carbonate with an excess, preferably about 2 to 0 about 5 equivalents, of a tnalkylamine, such as triethylamine, for about 0.5 to 2 hours, followed by about 1 0 to about 1 5 equivalents of a pnmary or secondary amine provides the carbamate Examples of amines suitable for Printed from Mimosa WO 99/06431 PCT/US98/15313 -- 90 - using in this reaction include, but are not limited to, piperazine, 1-methylpiperazine, 1-acetylpiperazme, morpholine, thiomorpholine, pyrrolidine, piperidme and the like. 5 Alternatively, in another method for preparing carbamates, a hydroxy- containing compound is contacted with about 1.0 to about 1.5 equivalents of a carbamyl chloride in an inert diluent, such as dichloromethane, at a temperature ranging from about 25°C to about 70°C for about 2 to about 72 hours. Typically, this reaction is conducted in the presence of a suitable base 10 to scavenge the acid generated during the reaction Suitable bases include, by way of example, tertiary amines, such as tnethylamme, diisopropylethylamme, iV-methylmorpholine and the like. Additionally, at least one equivalent (based on the hydroxy compound) of 4-(jV,Ar-dimethylamino)pyndine is preferably added to the reaction mixture to facilitate the reaction. Examples of carbamyl 15 chlorides suitable for use in this reaction include, by way of example, dimethylcarbamyl chlonde, diethylcarbamyl chlonde and the like. Likewise, when a compound of formula I or an intermediate thereof contains a pnmary or secondary hydroxyl group, such hydroxyl groups can be 20 readily converted into a leaving group and displaced to form, for example, amines, sulfides and fluondes. For example, denvatives of 4-hydroxy-L-proline can be converted into the corresponding 4-amino, 4-thio or 4-fluoro-L-proline denvatives via nucleophilic displacement of the denvatized hydroxyl group Generally, when a chiral compound is employed m these reactions, the 25 stereochemistry at the carbon atom attached to the derivatized hydroxyl group is typically inverted. These reactions are typically conducted by first converting the hydroxyl group into a leaving group, such as a tosylate, by treatment of the 30 hydroxy compound with at least one equivalent of a sulfonyl halide, such as p-toluenesulfonyl chlonde and the like, in pyndine. This reaction is generally conducted at a temperature of from about 0°C to about 70°C for about 1 to Printed from Mimosa WO 99/06431 PCT/US98/15313 -- 91 -- about 48 hours. The resulting tosylate can then be readily displaced with sodium azide, for example, by contacting the tosylate with at least one equivalent of sodium azide in an inert diluent, such as a mixture of NJf-dimethylformamide and water, at a temperature ranging from about 0°C to 5 about 37 °C for about 1 to about 12 hours to provide the corresponding azido compound. The azido group can then be reduced by, for example, hydrogenation using a palladium on carbon catalyst to provide the amino (-NH2) compound 10 Similarly, a tosylate group can be readily displaced by a thiol to form a sulfide. This reaction is typically conducted by contacting the tosylate with at least one equivalent of a thiol, such as thiophenol, in the presence of a suitable base, such as l,8-diazabicyclo[5.4.0]undec-7-ene (DBU), in an inert diluent, such as N,N-dimethylformamide, at a temperature of from about 0°C to about 15 37°C for about 1 to about 12 hours to provide the sulfide. Additionally, treatment of a tosylate with morphohnosulfur trifluoride m an inert diluent, such as dichloromethane, at a temperature ranging from about 0°C to about 37°C for about 12 to about 24 hours affords the corresponding fluoro compound. 20 Furthermore, a compound of formula I or an intermediate thereof having a substituent containing an lodoaryl group, for example, when R5 is a (4-iodophenyl)methyl group, can be readily converted either before or after the above coupling reactions into a biaryl compound Typically, this reaction is 25 conducted by treating the iodoaryl compound with about 1 1 to about 2 equivalents of an arylzmc iodide, such as 2-(methoxycarbonyl)phenylzinc iodide, in the presence of a palladium catalyst, such as palladium tetra(tnphenylphosphme), in an inert diluent, such as tetrahydrofuran, at a temperature ranging from about 24°C to about 30°C until reaction 30 completion This reaction is further described, for example, in Rieke, J Org Chem 1991,56,1445. Printed from Mimosa WO 99/06431 PCT/US98/15313 - 92 - In some cases, the compounds of formula I or intermediates thereof may contain substituents having one or more sulfur atoms Such sulfur atoms will be present, for example, when the amino acid of formula II employed in the above reactions is derived from L-thiazolidine-4-carboxylic acid, L-(5,5-5 dimethyl)thiazolidine-4-carboxylic acid, L-thiamorphohne-3-carboxylic acid and the like. When present, such sulfur atoms can be oxidized either before or after the above coupling reactions to provide a sulfoxide or sulfone compound using conventional reagents and reaction conditions Suitable reagents for oxidizing a sulfide compound to a sulfoxide include, by way of example, 10 hydrogen peroxide, 3-chloroperoxybenzoic acid (MCPBA), sodium periodate and the like The oxidation reaction is typically conducted by contacting the sulfide compound with about 0 95 to about 1 1 equivalents of the oxidizing reagent in an inert diluent, such as dichloromethane, at a temperature ranging from about -50°C to about 75 °C for about 1 to about 24 hours. The resulting 15 sulfoxide can then be further oxidized to the corresponding sulfone by contacting the sulfoxide with at least one additional equivalent of an oxidizing reagent, such as hydrogen peroxide, MCPBA, potassium permanganate and the like. Alternatively, the sulfone can be prepared directly by contacting the sulfide with at least two equivalents, and preferably an excess, of the oxidizing 20 reagent. Such reactions are described further in March, "Advanced Organic Chemistry", 4th Ed., pp 1201-1202, Wiley Publisher, 1992. As described above, the compounds of formula I having an R2 substituent other an hydrogen can be prepared using an /^-substituted amino 25 acid of formula II, such as sarcosine, N-methyl-L-phenylalanme and the like, in the above-descnbed coupling reactions Alternatively, such compounds can be prepared by /V-alkylation of a sulfonamide of formula I or IV (where R2 is hydrogen) using conventional synthetic procedures. Typically, this N-alkylation reaction is conducted by contacting the sulfonamide with at least 30 one equivalent, preferably 1 1 to 2 equivalents, of an alkyl or substituted alkyl halide in the presence of a suitable base, such as potassium carbonate, in an inert diluent, such as acetone, 2-butanone and the like, at a temperature Printed from Mimosa WO 99/06431 PCT/US98/15313 -- 93 -- ranging from about 25°C to about 70°C for about 2 to about 48 hours. Examples of alkyl or substituted alkyl halides suitable for use in this reaction include, but are not limited to, methyl iodide, and the like 5 Additionally, the sulfonamides of formula I or IV wherein R2 is hydrogen and R1 is a 2-alkoxycarbonylaryl group can be intramolecularly cyclized to form 1,2-benzisothiazol-3-one denvatives or analogues thereof This reaction is typically conducted by treating a sulfonamide, such as N-(2-methoxycarbonylphenylsulfonyl)glycine-L-phenylalanine benzyl ester, with 0 about 1 0 to 1 5 equivalents of a suitable base, such as an alkali metal hydnde, in a inert diluent, such as tetrahydrofuran, at a temperature ranging from about 0°C to about 30°C for about 2 to about 48 hours to afford the cyclized 1,2-benzisothiazol-3-one denvative. 5 Lastly, the compounds of formula I where Q is -C(S)NR7- are can prepared by using an amino thionoacid denvative in place of ammo acid II in the above descnbed synthetic procedures Such amino thionoacid denvatives can be prepared by the procedures descnbed in Shalaky, et al., J Org. Chem , 61:9045-9048 (1996) and Brain, et al, J Org Chem , 62 3808-3809 (1997) D and references cited therein Pharmaceutical Formulations When employed as pharmaceuticals, the compounds of formula I and IA are usually administered in the form of pharmaceutical compositions. 5 These compounds can be administered by a vanety of routes including oral, rectal, transdermal, subcutaneous, intravenous, intramuscular, and intranasal. These compounds are effective as both injectable and oral compositions Such compositions are prepared in a manner well known in the pharmaceutical art and compnse at least one active compound 0 This invention also includes pharmaceutical compositions which contain, as the active ingredient, one or more of the compounds of formula I Printed from Mimosa WO 99/06431 PCT/US98/15313 -- 94 -- and IA above associated with pharmaceutical^ acceptable earners In making the compositions of this invention, the active ingredient is usually mixed with an excipient, diluted by an excipient or enclosed within such a earner which can be in the form of a capsule, sachet, paper or other container. When the 5 excipient serves as a diluent, it can be a solid, semi-solid, or liquid matenal, which acts as a vehicle, earner or medium for the active ingredient. Thus, the compositions can be in the form of tablets, pills, powders, lozenges, sachets, cachets, elixirs, suspensions, emulsions, solutions, syrups, aerosols (as a solid or in a liquid medium), ointments containing, for example, up to 10% by 10 weight of the active compound, soft and hard gelatin capsules, suppositones, stenle injectable solutions, and stenle packaged powders. In preparing a formulation, it may be necessary to mill the active compound to provide the appropnate particle size prior to combining with the 15 other ingredients If the active compound is substantially insoluble, it ordinanly is milled to a particle size of less than 200 mesh. If the active compound is substantially water soluble, the particle size is normally adjusted by milling to provide a substantially uniform distnbution in the formulation, e.g about 40 mesh 20 Some examples of suitable excipients include lactose, dextrose, sucrose, sorbitol, mannitol, starches, gum acacia, calcium phosphate, alginates, tragacanth, gelatin, calcium silicate, microcrystalline cellulose, polyvinylpyrrolidone, cellulose, water, syrup, and methyl cellulose The 25 formulations can additionally include: lubneating agents such as talc, magnesium stearate, and mineral oil; wetting agents, emulsifying and suspending agents; preserving agents such as methyl- and propylhydroxy-benzoates; sweetening agents, and flavonng agents.

The term "unit dosage forms" refers to physically discrete units suitable as unitary dosages for human subjects and 5 other mammals, each unit containing a predetermined quantity of active material calculated to produce the desir°a therapeutic effect, in association with a suitable pharmaceutical excipient The active compound is effective over a wide dosage range and is 10 generally administered in a pharmaceutical^ effective amount It, will be understood, however, that the amount of the compound actually administered will be determined by a physician, in the light of the relevant circumstances, including the condition to be treated, the chosen route of administration, the actual compound administered, the age, weight, and response of the individual 15 patient, the severity of the patient's symptoms, and the like. For preparing solid compositions such as tablets, the principal active ingredient is mixed with a pharmaceutical excipient to form a solid preformulation composition containing a homogeneous mixture of a 20 compound of the present invention When referring to these preformulation compositions as homogeneous, it is meant that the active ingredient is dispersed evenly throughout the composition so that the composition may be readily subdivided into equally effective unit dosage forms such as tablets, pills and capsules This solid preformulation is then subdivided into unit 25 dosage forms of the type descnbed above containing from, for example, 0 1 to about 500 mg of the active ingredient of the present invention The tablets or pills of the present invention may be coated or otherwise compounded to provide a dosage form affording the advantage of prolonged 30 action For example, the tablet or pill can compnse an inner dosage and an outer dosage component, the latter being in the form of an envelope over the former. The two components can separated by entenc layer which serves to Printed from Mimosa WO 99/06431 PCT/US98/15313 - 96 -- resist disintegration in the stomach and permit the inner component to pass intact into the duodenum or to be delayed in release. A variety of matenals can be used for such enteric layers or coatings, such matenals including a number ofpolymenc acids and mixtures of polymenc acids with such 5 matenals as shellac, cetyl alcohol, and cellulose acetate.

The liquid or solid compositions may contain suitable pharmaceutically acceptable excipients as descnbed supra. Preferably the compositions are administered by the oral or nasal respiratory route for local or systemic effect. Compositions in preferably pharmaceutically acceptable solvents may be nebulized by use of inert gases Nebulized 20 solutions may be breathed directly from the nebulizing device or the nebulizing device may be attached to a face masks tent, or intermittent positive pressure breathing machine Solution, suspension, or powder compositions may be administered, preferably orally or nasally, from devices which deliver the formulation in an appropnate manner 25 The following formulation examples illustrate the pharmaceutical compositions of the present invention Formulation Example 1 30 Hard gelatin capsules containing the following ingredients are prepared: Printed from Mimosa WO 99/06431 PCT/US98/15313 10 15 - 97 -- Quantity Ingredient (mg/capsule) Active Ingredient 30 0 Starch 305.0 Magnesium stearate 5.0 The above ingredients are mixed and filled into hard gelatin capsules in 340 mg quantities.

Such transdermal Printed from Mimosa WO 99/06431 PCT/U S98/15313 - 101 -- patches may be used to provide continuous or discontinuous infusion of the compounds of the present invention in controlled amounts The construction and use of transdermal patches for the delivery of pharmaceutical agents is well known in the art. See, e.g., U.S Patent 5,023,252, issued June 11, 1991, 5 herein incorporated by reference Such patches may be constructed for continuous, pulsatile, or on demand delivery of pharmaceutical agents When it is desirable or necessary to introduce the pharmaceutical composition to the brain, either directly or indirectly Direct techniques 10 usually involve placement of a drug delivery catheter into the host's ventncular system to bypass the blood-brain barrier. One such implantable delivery system used for the transport of biological factors to specific anatomical regions of the body is described in U S Patent 5,011,472 which is herein incorporated by reference. 15 Indirect techniques, which are generally preferred, usually involve formulating the compositions to provide for drug latentiation by the conversion of hydrophilic drugs into lipid-soluble drugs. Latentiation is generally achieved through blocking of the hydroxy, carbonyl, sulfate, and 20 pnmary amine groups present on the drug to render the drug more lipid soluble and amenable to transportation across the blood-brain bamer. Alternatively, the delivery of hydrophilic drugs may be enhanced by mtra-artenal infusion of hypertonic solutions which can transiently open the blood-brain banner 25 Utility The compounds of this invention can be employed to bind VLA-4 (a4P, integnn) in biological samples and, accordingly have utility in, for example, assaying such samples for VLA-4. In such assays, the compounds can be 30 bound to a solid support and the VLA-4 sample added thereto. The amount of VLA-4 in the sample can be determined by conventional methods such as use of a sandwich ELISA assay Alternatively, labeled VLA-4 can be used in a Printed from Mimosa WO 99/06431 PCT/US98/15313 -- 102 -- competitive assay to measure for the presence of VLA-4 in the sample. Other suitable assays are well known m the art In addition, certain of the compounds of this invention inhibit, in vivo, 5 adhesion of leukocytes to endothelial cells mediated by VLA-4 and, accordingly, can be used in the treatment of diseases mediated by VLA-4 Such diseases include inflammatory diseases m mammalian patients such as asthma, Alzheimer's disease, atherosclerosis, AIDS dementia, diabetes (including acute juvenile onset diabetes), inflammatory bowel disease 3 (including ulcerative colitis and Crohn's disease), multiple sclerosis, rheumatoid arthritis, tissue transplantation, tumor metastasis, meningitis, encephalitis, stroke, and other cerebral traumas, nephritis, retinitis, atopic dermatitis, psoriasis, myocardial ischemia and acute leukocyte-mediated lung injury such as that which occurs in adult respiratory distress syndrome. The biological activity of the compounds identified above may be assayed in a variety of systems. For example, a compound can be immobilized on a solid surface and adhesion of cells expressing VLA-4 can be measured Using such formats, large numbers of compounds can be screened. Cells suitable for 3 this assay include any leukocytes known to express VLA-4 such as T cells, B cells, monocytes, eosinophils, and basophils. A number of leukocyte cell lines can also be used, examples include Jurkat and U937. The test compounds can also be tested for the ability to competitively 5 inhibit binding between VLA-4 and VCAM-1, or between VLA-4 and a labeled compound known to bind VLA-4 such as a compound of this invention or antibodies to VLA-4. In these assays, the VCAM-1 can be immobilized on a solid surface VCAM-1 may also be expressed as a recombinant fusion protein having an Ig tail (e g, IgG) so that binding to 0 VLA-4 may be detected in an immunoassay Alternatively, VCAM-1 expressing cells, such as activated endothelial cells or VCAM-1 transfected fibroblasts can be used. For assays to measure the ability to block adhesion to Printed from Mimosa WO 99/06431 PCT/US98/15313 -- 103 -- brain endothelial cells, the assays described in International Patent Application Publication No. WO 91/05038 are particularly preferred This application is incorporated herein by reference in its entirety. 5 Many assay formats employ labelled assay components The labelling systems can be in a vanety of forms. The label may be coupled directly or indirectly to the desired component of the assay according to methods well known in the art. A wide vanety of labels may be used. The component may be labelled by any one of several methods The most common method of 10 detection is the use of autoradiography with 3H, 1251, 35S, l4C, or 32P labelled compounds or the like. Non-radioactive labels include hgands which bind to labelled antibodies, fluorophores, chemiluminescent agents, enzymes and antibodies which can serve as specific binding pair members for a labelled ligand. The choice of label depends on sensitivity required, ease of 15 conjugation with the compound, stability requirements, and available instrumentation. Appropnate in vivo models for demonstrating efficacy in treating inflammatory responses include EAE (expenmental autoimmune 20 encephalomyelitis) in mice, rats, guinea pigs or primates, as well as other inflammatory models dependent upon a4 mtegnns. Compounds having the desired biological activity may be modified as necessary to provide desired properties such as improved pharmacological 25 properties (e.g., in vivo stability, bio-availability), or the ability to be detected in diagnostic applications For instance, inclusion of one or more D-amino acids m the sulfonamides of this invention typically increases m vivo stability Stability can be assayed in a vanety of ways such as by measunng the half-life of the proteins during incubation with peptidases or human plasma or serum 30 A number of such protein stability assays have been descnbed (see, e g , Verhoef, et al., Eur. J Drug Metab Pharmacokinet, 1990,15£2)'83-93) Printed from Mimosa WO 99/06431 PCT/US98/15313 -- 104 — For diagnostic purposes, a wide vanety of labels may be linked to the compounds, which may provide, directly or indirectly, a detectable signal. Thus, the compounds of the subject invention may be modified in a vanety of ways for a vanety of end purposes while still retaining biological activity. In 5 addition, vanous reactive sites may be introduced at the terminus for linking to particles, solid substrates, macromolecules, or the like Labeled compounds can be used in a vanety of in vivo or in vitro applications A wide vanety of labels may be employed, such as radionuclides 10 (e.g., gamma-emitting radioisotopes such as technetium-99 or indium- 111), fluorescers (e.g , fluorescein), enzymes, enzyme substrates, enzyme cofactors, enzyme inhibitors, chemiluminescent compounds, bioluminescent compounds, and the like. Those of ordinary skill m the art will know of other suitable labels for binding to the complexes, or will be able to ascertain such using 15 routine expenmentation. The binding of these labels is achieved using standard techniques common to those of ordinary skill in the art In vitro uses include diagnostic applications such as monitonng inflammatory responses by detecting the presence of leukocytes expressing 20 VLA-4 The compounds of this invention can also be used for isolating or labeling such cells. In addition, as mentioned above, the compounds of the invention can be used to assay for potential inhibitors of VLA-4/VCAM-1 interactions 25 For in vivo diagnostic imaging to identify, e.g , sites of inflammation, radioisotopes are typically used in accordance with well known techniques The radioisotopes may be bound to the peptide either directly or indirectly using intermediate functional groups For instance, chelating agents such as diethylenetnaminepentacetic acid (DTPA) and ethylenediaminetetraacetic acid 30 (EDTA) and similar molecules have been used to bind proteins to metallic ion radioisotopes. Printed from Mimosa WO 99/06431 PCT/US98/15313 -- 105 - The complexes can also be labeled with a paramagnetic isotope for purposes of in vivo diagnosis, as in magnetic resonance imaging (MRI) or electron spin resonance (ESR), both of which were well known. In general, any conventional method for visualizing diagnostic imaging can be used 5 Usually gamma- and positron-emitting radioisotopes are used for camera imaging and paramagnetic isotopes are used for MRI Thus, the compounds can be used to monitor the course of amelioration of an inflammatory response m an individual. By measuring the increase or decrease in lymphocytes expressing VLA-4 it is possible to determine whether a particular therapeutic 10 regimen aimed at ameliorating the disease is effective The pharmaceutical compositions of the present invention can be used to block or inhibit cellular adhesion associated with a number of diseases and disorders. For instance, a number of inflammatory disorders are associated 15 with integnns or leukocytes. Treatable disorders include, e.g , transplantation rejection (e g , allograft rejection), Alzheimer's disease, atherosclerosis, AIDS dementia, diabetes (including acute juvenile onset diabetes), retinitis, cancer metastases, rheumatoid arthritis, acute leukocyte-mediated lung injury (e g , adult respiratory distress syndrome), asthma, nephritis, and acute and chronic 20 inflammation, including atopic dermatitis, psoriasis, myocardial ischemia, and inflammatory bowel disease (including Crohn's disease and ulcerative colitis). In preferred embodiments the pharmaceutical compositions are used to treat inflammatory brain disorders, such as multiple sclerosis (MS), viral meningitis and encephalitis. 25 Inflammatory bowel disease is a collective term for two similar diseases referred to as Crohn's disease and ulcerative colitis. Crohn's disease is an idiopathic, chronic ulceroconstnctive inflammatory disease characterized by sharply delimited and typically transmural involvement of all layers of the 30 bowel wall by a granulomatous inflammatory reaction. Any segment of the gastrointestinal tract, from the mouth to the anus, may be involved, although the disease most commonly affects the terminal ileum and/or colon. Printed from Mimosa WO 99/06431 PCT/US98/15313 -- 106 -- Ulcerative colitis is an inflammatory response limited largely to the colonic mucosa and submucosa Lymphocytes and macrophages are numerous in lesions of inflammatory bowel disease and may contnbute to inflammatory injury. 5 Asthma is a disease characterized by increased responsiveness of the tracheobronchial tree to various stimuli potentiating paroxysmal constriction of the bronchial airways The stimuli cause release of various mediators of inflammation from IgE-coated mast cells including histamine, eosinophilic 10 and neutrophilic chemotactic factors, leukotnnes, prostaglandin and platelet activating factor Release of these factors recruits basophils, eosinophils and neutrophils, which cause inflammatory injury. Atherosclerosis is a disease of arteries (e.g , coronary, carotid, aorta and 15 iliac). The basic lesion, the atheroma, consists of a raised focal plaque within the intima, having a core of lipid and a covering fibrous cap. Atheromas compromise arterial blood flow and weaken affected arteries. Myocardial and cerebral infarcts are a major consequence of this disease Macrophages and leukocytes are recruited to atheromas and contnbute to inflammatory injury 20 Rheumatoid arthntis is a chronic, relapsing inflammatory disease that pnmanly causes impairment and destruction of joints Rheumatoid arthntis usually first affects the small joints of the hands and feet but then may involve the wnsts, elbows, ankles and knees The arthntis results from interaction of 25 synovial cells with leukocytes that infiltrate from the circulation into the synovial lining of the joints. See e g, Paul, Immunology (3d ed., Raven Press, 1993). Another indication for the compounds of this invention is in treatment of 30 organ or graft rejection mediated by VLA-4 Over recent years there has been a considerable improvement in the efficiency of surgical techniques for transplanting tissues and organs such as skin, kidney, liver, heart, lung, Printed from Mimosa WO 99/06431 PCT/US98/I5313 -- 107 - pancreas and bone marrow Perhaps the principal outstanding problem is the lack of satisfactory agents for inducing immunotolerance in the recipient to the transplanted allograft or organ When allogeneic cells or organs are transplanted into a host (i.e., the donor and donee different individuals 5 from the same species), the host immune system is likely to mount an immune response to foreign antigens in the transplant (host-versus-graft disease) leading to destruction of the transplanted tissue. CD8* cells, CD4 cells and monocytes are all involved in the rejection of transplant tissues Compounds of this invention which bind to alpha-4 integnn are useful, inter alia, to block 10 alloantigen-induced immune responses in the donee thereby preventing such cells from participating in the destruction of the transplanted tissue or organ See, eg, Paul et al., Transplant International 9, 420-425 (1996), Georczynski et al., Immunology 87, 573-580 (1996); Georcyznski et al, Transplant Immunol 3, 55-61 (1995); Yang et al., Transplantation 60, 71-76 (1995); Anderson et al., APMIS 102, 23-27 (1994) A related use for compounds of this invention which bind to VLA-4 is in modulating the immune response involved in "graft versus host" disease (GVHD) See eg, Schlegel et al., J Immunol 155, 3856-3865 (1995) GVHD is a potentially fatal disease that occurs when immunologically competent cells are transferred to an allogeneic recipient. In this situation, the donor's immunocompetent cells may attack tissues in the recipient. Tissues of the skin, gut epithelia and liver are frequent targets and may be destroyed during the course of GVHD The disease presents an especially severe problem when immune tissue is being transplanted, such as in bone marrow transplantation; but less severe GVHD has also been reported in other cases as well, including heart and liver transplants The therapeutic agents of the present invention are used, inter alia, to block activation of the donor T-cells thereby interfering with their ability to lyse target cells m the host. A further use of the compounds of this invention is inhibiting tumor metastasis. Several tumor cells have been reported to express VLA-4 and Printed from Mimosa WO 99/06431 PCT/US98/15313 - 108 -- compounds which bind VLA-4 block adhesion of such cells to endothelial cells. Steinback et al., Urol Res. 23, 175-83 (1995); Orosz et al., Int. J. Cancer 60, 867-71 (1995), Freedman et al, Leuk. Lymphoma 13, 47-52 (1994); Okahara et al., Cancer Res 54, 3233-6 (1994). A further use of the compounds of this invention is in treating multiple sclerosis. Multiple sclerosis is a progressive neurological autoimmune disease that affects an estimated 250,000 to 350,000 people in the United States Multiple sclerosis is thought to be the result of a specific autoimmune reaction in which certain leukocytes attack and initiate the destruction of myelin, the insulating sheath covering nerve fibers. In an animal model for multiple sclerosis, murine monoclonal antibodies directed against VLA-4 have been shown to block the adhesion of leukocytes to the endothelium, and thus prevent inflammation of the central nervous system and subsequent paralysis in the animals16. Pharmaceutical compositions of the invention are suitable for use in a vanety of drug delivery systems. Suitable formulations for use in the present invention are found in Remington's Pharmaceutical Sciences, Mace Publishing Company, Philadelphia, PA, 17th ed (1985). In order to enhance serum half-life, the compounds may be encapsulated, introduced into the lumen of liposomes, prepared as a colloid, or other conventional techniques may be employed which provide an extended serum half-life of the compounds. A vanety of methods are available for preparing liposomes, as descnbed in, e g., Szoka, et al., U S.

Example 141 In vitro Assay For Determining Binding of 20 Candidate Compounds to VLA-4 An in vitro assay was used to assess binding of candidate compounds to a4p, mtegnn Compounds which bind in this assay can be used to assess VCAM-1 levels in biological samples by conventional assays (e.g., 25 competitive assays). This assay is sensitive to IC50 values as low as about InM. The activity of a4P, integnn was measured by the interaction of soluble VCAM-1 with Jurkat cells (e g , Amencan Type Culture Collection Nos. TIB 30 152, TIB 153, and CRL 8163), a human T-cell line which expresses high levels of a4P, integnn VCAM-1 interacts with the cell surface in an a4P, integrin-dependent fashion (Yednock, et al J. Bio Chem., 1995,220:28740) Recombinant soluble VCAM-1 was expressed as a chimenc fusion 35 protein containing the seven extracellular domains of VCAM-1 on the N- Printed from Mimosa WO 99/06431 PCT/US98/15313 -- 167 -- terminus and the human IgG, heavy chain constant region on the C-termmus. The VCAM-1 fusion protein was made and purified by the manner described by Yednock,supra. 5 Jurkat cells were grown in RPMI 1640 supplemented with 10% fetal bovine serum, penicillin, streptomycin and glutamme as descnbed by Yednock, supra. Jurkat cells were incubated with 1.5 mM MnCl, and 5 ng/mL 15/7 10 antibody for 30 minutes on ice. Mn~2 activates the receptor to enhance ligand binding, and 15/7 is a monoclonal antibody that recognizes an activated/ligand occupied conformation of a4P, integnn and locks the molecule into this conformation thereby stabilizing the VCAM-l/a4P, integnn interaction. Yednock, et al., supra. Antibodies similar to the 15/7 antibody have been 15 prepared by other investigators (Luque, et al, 1996, J Bio. Chem 221" 11067) and may be used in this assay. Cells were then incubated for 30 minutes at room temperature with candidate compounds, in various concentrations ranging from 66 nM to 0.01 20 |iM using a standard 5-pomt senal dilution. 15 soluble recombinant VCAM-1 fusion protein was then added to Jurkat cells and incubated for 30 minutes on ice (Yednock et al., supra.). Cells were then washed two times and resuspended in PE-conjugated goat 25 F(ab')2 anti-mouse IgG Fc (Immunotech, Westbrook, ME) at 1:200 and incubated on ice, in the dark, for 30 minutes. Cells were washed twice and analyzed with a standard fluorescence activated cell sorter ("FACS") analysis as descnbed in Yednock, et al, supra 30 Compounds having an IC50 of less than about 15nM possess binding affimty to a4p,. Printed from Mimosa WO 99/06431 PCT/US98/15313 -- 168 -- When tested in this assay, each of the compounds in Examples 1-135 has an IC50 of 15 /l/M or less 5 Example 142 In vitro Saturation Assay For Determining Binding of Candidate Compounds to a4P, The following describes an in vitro assay to determine the plasma levels 10 needed for a compound to be active in the Experimental Autoimmune Encephalomyelitis ("EAE") model, descnbed in the next example, or in other in vivo models. Log-growth Jurkat cells are washed and resuspended in normal animal 15 plasma containing 20 ng/ml of the 15/7 antibody (descnbed in the above example). The Jurkat cells are diluted two-fold into either normal plasma samples containing known candidate compound amounts in vanous concentrations 20 ranging from 66 nM to 0.01 |iM, using a standard 12 point senal dilution for a standard curve, or into plasma samples obtained from the penpheral blood of candidate compound-treated animals. Cells are then incubated for 30 minutes at room temperature, washed 25 twice with phosphate-buffered saline ("PBS") containing 2% fetal bovine serum and ImM each of calcium chlonde and magnesium chlonde (assay medium) to remove unbound 15/7 antibody. The cells are then exposed to phycoerythnn-conjugated goat F(ab')2 anti-30 mouse IgG Fc (Immunotech, Westbrook, ME), which has been adsorbed for any non-specific cross-reactivity by co-incubation with 5% serum from the animal species being studied, at 1:200 and incubated in the dark at 4°C for 30 minutes. Printed from Mimosa WO 99/06431 PCT/US98/1S313 -- 169 -- Cells are washed twice with assay medium and resuspended in the same. They are then analyzed with a standard fluorescence activated cell sorter ("FACS") analysis as described in Yednock et al J Bio. Chem , 1995, 270:28740. The data is then graphed as fluorescence versus dose, e g., in a normal dose-response fashion. The dose levels that result in the upper plateau of the curve represent the levels needed to obtain efficacy in an in vivo model. 10 This assay may also be used to determine the plasma levels needed to saturate the binding sites of other integnns, such as the a9P, integnn, which is the integnn most closely related Ojp, (Palmer et al, 1993, J Cell Bio., 123.1289) Such binding is predictive of in vivo utility for inflammatory conditions mediated by a9P, integnn, including by way of example, airway 15 hyper-responsiveness and occlusion that occurs with chronic asthma, smooth muscle cell proliferation in atherosclerosis, vascular occlusion following angioplasty, fibrosis and glomerular scarring as a result of renal disease, aortic stenosis, hypertrophy of synovial membranes in rheumatoid arthntis, and inflammation and scarnng that occur with the progression of ulcerative colitis 20 and Crohn's disease. Accordingly, the above-descnbed assay may be performed with a human colon carcinoma cell line, SW 480 (ATTC #CCL228) transfected with cDNA encoding a, integnn (Yokosaki et al, 1994, J Bio Chem , 269.26691), in 25 place of the Jurkat cells, to measure the binding of the a,p, integnn. As a control, SW 480 cells which express other a and P, subunits may be used. Accordingly, another aspect of this invention is directed to a method for treating a disease in a mammalian patient, which disease is mediated by a9P,, 30 and which method compnses admmistenng to said patient a therapeutically effective amount of a compound of this invention Such compounds are preferably administered in a pharmaceutical composition described herein Printed from Mimosa WO 99/06431 PCI7US98/15313 -- 170 -- above. Effective daily dosing will depend upon the age, weight, condition of the patient which factors can be readily ascertained by the attending clinician. However, in a preferred embodiment, the compounds are administered from about 20 to 500 ng/kg per day. 5 Example 143 In vivo Evaluation 10 The standard multiple sclerosis model, Experimental Autoimmune (or Allergic) Encephalomyelitis ("EAE"), was used to determine the effect of candidate compounds to reduce motor impairment in rats or guinea pigs. Reduction in motor impairment is based on blocking adhesion between leukocytes and the endothelium and correlates with anti-inflammatory activity 15 in the candidate compound. This model has been previously descnbed by Keszthelyi et al., Neurology, 1996,47 1053-i 059, and measures the delay of onset of disease. Brains and spinal cords of adult Hartley guinea pigs were homogenized in 20 an equal volume of phosphate-buffered saline. An equal volume of Freund's complete adjuvant (100 mg Mycobacterium tuberculosis plus 10 ml Freund's incomplete adjuvant) was added to the homogenate The mixture was emulsified by circulating it repeatedly through a 20 ml synnge with a penstaltic pump for about 20 minutes 25 Female Lewis rats (2-3 months old, 170-220 g) or Hartley guinea pigs (20 day old, 180-200 g) were anesthetized with isoflurane and three injections of the emulsion, 0.1 ml each, were made in each flank Motor impairment onset is seen in approximately 9 days 30 Candidate compound treatment began on Day 8, just before onset of symptoms. Compounds were administered subcutaneously ("SC"), orally ("PO") or intrapentoneally ("IP") Doses were given in a range of lOmg/kg to Printed from Mimosa WO 99/06431 PCT/US98/15313 -- 171 - 200 mg/kg, bid, for five days, with typical dosing of 10 to 100 mg/kg SC, 10 to 50 mg/kg PO, and 10 to 100 mg/kg IP. Antibody GG5/3 against a4p, integnn (Keszthelyi et al, Neurology, 1996, 5 47.1053-1059), which delays the onset of symptoms, was used as a positive control and was injected subcutaneously at 3 mg/kg on Day 8 and II. Body weight and motor impairment were measured daily. Motor impairment was rated with the following clinical score- 10 0 no change 1 tail weakness or paralysis 2 hindlimb weakness 3 hindlimb paralysis 15 4 moribund or dead A candidate compound was considered active if it delayed the onset of symptoms, e.g., produced clinical scores no greater than 2 or slowed body 20 weight loss as compared to the control When tested in this in vivo assay, the compounds of Examples 5, 12, 18 and 20 were active. 25 Example 144 Asthma Model Example Inflammatory conditions mediated by a4P, integnn include, for example, airway hyper-responsiveness and occlusion that occurs with chronic asthma. 30 The following describes an asthma model which can be used to study the in vivo effects of the compounds of this invention for use in treating asthma. Following the procedures descnbed by Abraham et al, J Clin. Invest, 93 776-787 (1994) and Abraham et al, Am J. Respir Cnt Care Med, 156 696-35 703 (1997), both of which are incorporated by reference in their entirety, Printed from Mimosa WO 99/06431 PCT/US98/15313 - 172 -- compounds of this invention are formulated into an aerosol and administered to sheep which are hypersensitive to Ascaris suum antigen. Compounds which decrease the early antigen-induced bronchial response and/or block the late-phase airway response, e.g, have a protective effect against antigen-induced 5 late responses and airway hyper-responsiveness ("AHR"), are considered to be active in this model. Allergic sheep which are shown to develop both early and late bronchial responses to inhaled Ascaris suum antigen are used to study the airway effects 10 of the candidate compounds. Following topical anesthesia of the nasal passages with 2% hdocaine, a balloon catheter is advanced through one nostril into the lower esophagus. The animals are then intubated with a cuffed endotracheal tube through the other nostril with a flexible fiberoptic bronchoscope as a guide. 15 Pleural pressure is estimated according to Abraham (1994). Aerosols (see formulation below) are generated using a disposable medical nebulizer that provides an aerosol with a mass median aerodynamic diameter of 3.2 nm as determined with an Andersen cascade impactor. The nebulizer is connected to 20 a dosimeter system consisting of a solenoid valve and a source of compressed air (20 psi). The output of the nebulizer is directed into a plastic T-piece, one end of which is connected to the inspiratory port of a piston respirator. The solenoid valve is activated for 1 second at the beginning of the inspiratory cycle of the respirator Aerosols are delivered at VT of 500 ml and a rate of 20 25 breaths/minute. A 0.5% sodium bicarbonate solution only is used as a control. To assess bronchial responsiveness, cumulative concentration-response 30 curves to carbachol can be generated according to Abraham (1994). Bronchial biopsies can be taken prior to and following the initiation of treatment and 24 Printed from Mimosa WO 99/06431 PCT/US98/15313 - 173 -- hours after antigen challenge. Bronchial biopsies can be preformed according to Abraham (1994). An in vitro adhesion study of alveolar macrophages can be performed 5 according to Abraham (1994), and a percentage of adherent cells is calculated Aerosol Formulation A solution of the candidate compound in 0.5% sodium bicarbonate/saline (w/v) at a concentration of 30.0 mg/mL is prepared using the following 10 procedure: A.
