Technical Field
The present invention relates to compounds that are useful for treating lammaiory and immune diseases, to pharmaceutical compositions comprising thesf ■npounds, and to methods of inhibiting inflammation or suppressing immune ponsc in a mammal.
Background
Inflammation results from a cascade of events that includes vasodilation ompanied by increased vascular permeability and exudation of fluid and plasma teins. This disruption of vascular integrity precedes or coincides with an Itration of inflammatory cells. Inflammatory mediators generated at the site of tne iai lesion serve to recruit inflammatory cells to the site of injury. These mediator^ ;mokines such as IL-8, MCP-l, MIP-l, and RANTES, complement fragments an**

lipid mediators) have chcmotactic activity for leukocytes and attract the inflammatory cells to the inflamed lesion. These chemotactic mediators which cause circulating leukocytes to localize at the site of inflammation require the cells to cross the vascular endothelium at a precise location. This leukocyte recruitment is accomplished by a process called cell adhesion.
Celi adhesion occurs through a coordinately regulated series of steps that allow the leukocytes to first adhere to a specific region of the vascular endothelium and then cross the endothelial barrier to migrate to the inflamed tissue (Springer, T A., 1994, Traffic Signals for Lymphocyte Recirculation and Leukocyte Emigration: The Multistep Paradigm. Cell 76: 301-314: Lawrence, M. B.. and Springer, T. A.. 1991, Leukocytes' Roll on a Seleclin at Physiologic Flow Rates: Distinction from and Prerequisite for Adhesion Through Integrins, Ccll.65: 859-873: von Adrian. U., Chambeis, J. D., McEnvoy. L.M., Bargztze, R.F., Arfos, K..E. and Butcher. E.C., 1991, Two-Step Model of Leukocyte-Endothelial Cell Interactions in Inflammation. Proc. Natl. Acad. Sci. USA 88: 7538-7542; and Ley. K.. Gaehtgens. P.. Fennie, C, Singer, M.S., Lasky, L.H. and Rosen. S.D.,1991, Lectin-Like Cell Adhesion Molecule 1 Mediates Rolling in Mesenteric Venules in vivo, Blood 77: 2553-2555). These steps are mediated by famiiies of adhesion molecules such as integrins, Ig supergene family members, and selectins which are expressed on the surface of the circulating leukocytes and on the vascular endothelial cells. The first step consists of leukocytes rolling along the vascular endothelial cell lining in the region of inflammation. The rolling step is mediated by an interaction between a leukocyte surface oligosaccharide.

such as Sialylated Le^is-X antigen (SLe*), and a selectin molecule expressed on the surface of the endothelial eel] in the region of inflammation. The selectin molecule is not normally expressed on the surface of endothelial ceils but rather is induced by the action of inflammatory mediators such as TNF-a andinterieukin-1. Rolling decreases the velocity of the circulating leukocyte in the region of inflammation and allows the cells to more firmJy_a«}herB to the endothelial cell. The firm adhesion is accomplished by the interaction of integrin molecules that are present on the surface of the rolling leukocytes and their counter-receptors (the Ig superfamily molecules) on the surface of the endothelial cell. The Ig superfamily molecules or CAMs (Cell Adhesion Molecules) are either dot expressed or are expressed at low levels on normal vascular endothelial, cells. The CAM's, like the selectins, are induced by the action of inflammatory mediators like TNF-alpha and IL-1. The final event in the adhesion process is the extravasation of leukocytes through the endothelial cell barrier and their migration along a chernotactic gradient to the site of inflammation. This transmigration is mediated by the conversion of the leukocyte integrin from a low avidity state to a high avidity state. The adhesion process relies on the induced expression of selecting and CAM's on the surface of vascular endothelial cells to mediate the rolling and firm adhesion of leukocytes to the vascular endothelium. ) The interaction of the intercellular adhesion molecule ICAM-I (cd54) on endothelial cells with the integrin LFA-1 on leukocytes plays an important role in endothelial-leukocyte contact. Leukocytes bearing high-affinity LFA-1 adhere to endothelial cells through interaction with 1CAM-1. initiating the process of

extravasation from the vasculature into the surrounding tissues. Thus, an agent which blocks the ICAM- 1/LFA-l interaction suppresses these early steps in the inflammatory response. Consistent with this background, ICAM-I knockout mice have numerous abnormalities in their inflammatory responses.
The present invention discloses compounds which bind to the interaction-domain (I-domain) of LFA-1, thus interrupting endothelial eel I-leukocyte adhesion by blocking the interaction of LFA-1 with 1CAM-1, ICAM-3, and other adhesion molecules. These compounds are useful for the treatment or prophylaxis of diseases in which leukocyte trafficking plays a role, notably acute and chronic inflammatory diseases, autoimmune diseases, tumor metastasis, allograft rejection, and reperfusion injury. The compounds of this invention arsdiaryl sulfides^ which arc substituted with a cinnamide moiety. The cinnamide functionality may be placed either ortho- Or para- to the linking sulfur atom, although para-substitution is preferable. - Appropriate substitution of both aromatic rings is tolerated, and can be used to modulate a variety of biochemical, physicochemical and pharmacokinetic properties. In particular the amide moiety is readily modified; a variety of secondary and tertiary amides are active, and alternatively a heterocyclic ring may be attached at this position. Modifications of this amide functionality are particularly useful in modulating physicochemical and pharmacokinetic properties.

Pharmaceutical Compositions and Methods of Treatment
The present invention also provides pharmaceutical compositions which comprise compounds of the present invention formulated together with one or more pharmaceutically-acceptable carriers. The pharmaceutical compositions may be specially formulated for oral administration in solid or liquid form, for parenteral injection, or for rectal administration.
The pharmaceutical compositions of this invention can be administered to humans and other animals orally, recially, paremerally, inlracisternally. -intra vaginally, intraperitoneally, topically (as by powders, ointments, or drops), bucally, or as an oral or nasal spray. The term "parenteral" administration as used herein refers to modes of administration which include intravenous, intramuscular, intraperitoneal, intrastcrnal, subcutaneous and intraarticular injection and infusion.
Pharmaceutical compositions of this invention for parenteral injection comprise pharmaceuticalJy-acceptable sterile aqueous or nonaqueous solutions, dispersions, suspensions or emulsions as well as sterile powders for reconstitutbn into sterile injectable solutions or dispersions just prior to use. Examples of suitable aqueous and nonaqueous carriers, diluents, solvents or vehicles include water.

ethanol, polyois (such as glycerol, propylene glycol, polyethylene glycol, and the like), and suitable mixtures thereof, vegetable oils (such as olive oil), and injectable organic esters such as ethyl oleate. Proper fluidity can be maintained, for example, by the use of coating materials such as lecithin, by the maintenance of the required particle size in the case of dispersioa'?, and by the use of surfactants.
These compositions may also contain adjuvants such as preservative, wetting agents, emulsifying agents, and dispersing agents. Prevention of the action of microorganisms may be ensured by the inclusion of various antibacterial and antifungal agents, for example, paraben, chlorobutanol, phenol sorbic acid, and the like. It may also be desirable to include isotonic agents such as sugars, sodium chloride, and the like. Prolonged absorption of the injectable pharmaceutical form may be brought about hy the inclusion of agents which delay absorption such as aluminum monostcaratc and gelatin.
In some cases, in order 10 prolong the effect of the drug, it is desirable to slow the absorption of the drug from subcutaneous or intramuscular injection. This may be accomplished by the use of a liquid suspension of crystalline or amorphous material with poor water solubility. The rate of absorption of the drug then depends upon its rate of dissolution which, in lum, may depend upon crystal size and crystalline form. Alternatively, delayed absorption of a parenterally administered drug form is accomplished by dissolving or suspending the drug in an oil vehicle.
Injectable depot forms are made by forming microencapsule matrices of the drug in biodegradable polymers such as polylactide-polyglycolide. Depending upon.

IP I
the ratio of drug to polymer and the nature of the particular polymer employed, the rate of drug release can be controlled. Examples of other biodegradable polymers include poly(orthoesters) and poly (anhydrides). Depot injectable formulations are also prepared by entrapping the drug in liposomes or micraemulsions which are compatible with body tissues.
The injectable formulations can be sterilized, for example, by filtration through a bacterial-retaining filter, or by incorporating sterilizing agents in the form of sterile solid compositions which can be dissolved or dispersed in sterile water or other sterile injectable medium just prior to use.
Solid dosage forms for oral admini strati on include capsules, tablets, pills, powders, and granules, in such solid dosage forms, the active compound is mixed with at least one inert, pharmaceutically-acceptable excipient or carrier such as sodium citrate or dicalcium phosphate and/or (a) fillers or extenders such as starches, lactose, sucrose, glucose, mamutol. and silicic acid, (b) binders such as, for example, carboxy methyl cellulose, alginates, gelatin, polyvinylpyrrolidone, sucrose, and acacia, (c) humectants such as glycerol, (d) disintegrating agents such as agar-agar, calcium carbonate, potato or tapioca starch, alginic acid, certain silicates, and sodium carbonate, (e) solution retarding agents such as paraffin, (f) absorption accelerators such as quaternary ammonium compounds, (g) wetting agents such as, for example, cetyl alcohol and glycerol monostearate, (h) absorbents such as kaolin and bentonim clay, and (I) lubricants such as talc, calcium stearate, magnesium stcarate, solid

polyethylene glycols, sodium lauryl sulfate, and mixtures thereof. In the case of capsules, tablets and pills, the dosage form may also comprise buffering agents.
Solid compositions of a similar type may also be employed as fillers in soft and hard-filled gelatin capsules using such excipients as lactose or milk sugar as well as high molecular weight polyethylene glycols and the like.
The solid dosage forms of tablets, dragees, capsules, pills, and granules can be prepared with coatings and shells such as enteric coatings and other coatings well known in the pharmaceutical formulating art. They may optionally contain opacifying agents and can also be of a composition that they release the active ingredient(s) only, or preferentially, in a certain part of the intestinal tract, optionally, in a delayed manner. Examples of embedding compositions which can be used include polymeric substances and waxes.
The active compounds can also be in micro-encapsulated form, tf appropriate, with one or more of the above-mentioned excipients.
Liquid dosage forms for oral administration include pharmaceuti'caKy-acceptable emulsions, solutions, suspensions, syrups and elixirs. In addition to the active compounds, the liquid dosage forms may contain inert diluents commonly used in the art such as, for example, water or other solvents, solubilizing agents and emuisifiers such as ethyl alcohol, isopropyl alcohol, ethyl carbonate, ethyl acetate, benzyl alcohol, benzyl benzoaie, propylene glycol, 1,3-butylene glycol, dimethyl formamide, oils (in particular, cottonseed, groundnut, com, germ, olive, castor, and

iesame oils), glycerol, tetrahydrofurfury] alcohol, polyethylene glycols and fatty acid ssters of sorbitan, and mixtures thereof.
Besides inert diluents, the oral compositions can also include adjuvants such is wetting agents, emulsifying and suspending agents, sweetening, flavoring, and perfuming agents.
Suspensions, in addition to the active compounds, may contain suspending igents as, for example, ethoxylated isostearyl alcohols, polyoxyethylene sorbitol and sorbitan esters, microcrystalline cellulose, aluminum metahydroxide, bemomte, agar, igar, and tragacanth, and mixtures thereof.
Compositions for rectal or vaginal administration are preferably suppositories which can be prepared by mixing the compounds of this invention with suitable noiv. rritating excipients or carriers such as cocoa butter, polyethylene glycol or a suppository wax which are solid at room temperature but liquid at body temperature uid therefore melt in the rectum or vaginal cavity and release the active compound.
Compounds of the present invention can also be administered in the form of iposomes. As is known in the art, liposomes are generally derived from jhospholipids or other lipid substances. Liposomes are formed by mono- or multi-amellar hydrated liquid crystals that are dispersed in an aqueous medium. Any non-oxic, physiologically-acceptable and metabolizable lipid capable of forming iposomes can be used. The present compositions in liposome form can contain, in addition to a compound of the present invention, stabilizers, preservatives, excipients,

and the like. The preferred lipids are the phospholipids and the phosphatidyl cholines (lecithins), both natural and synthetic.

Preparation of Compounds of the Invention
The compounds and processes of the present invention may be better understood in connection with the following synthetic Schemes which illustrate the methods by which the compounds of the invention can be prepared.

Scheme ! describes the synthesis of a typical cinnamide-substituted diaryl sulfide 4 through an aldehyde intermediate 2. Aldehyde 2 is prepared by reaction of a thiophenol (for example 2.4-dichlorothiophenol, 2-bromoihiophenoi. or the like) with halo-substituted benzaldehyde derivative 1 (e.g. 2-chlorobenzaldehydc, 3-chloro,4-fluorobcnzaldehyde, or the like) in the presence of base (e.g. sodium carbonate, triethylamine, or the like) and a polar solvent (e.g. dimethylformamide, dimethy [sulfoxide, or the like). The aldehyde group is homologated to the corresponding cinnamic acid 3, using an acetate equivalent (for example, malonic I acid, triethoxypbosphonoacetale, or the like) in the presence of an appropriate base and solvent. In some cases, it may be necessary to hydrolyze an intermediate ester (for example using sodium hydroxide in alcohol). The acid group is activated (for

example using thionyl chloride, or dicyclohexylcarbodiimide and N-hydroxysuccinimide, or the like) and reacted with a primary or secondary amine (for example, 5-aminohexanol, pyrrol idone-3-propylamine, or ihe like) to provide the desired anaiog 4. In one variant, a halo-acetophenone can replace bcnzaldehyde 2; the resultant cinnamides 4 are substituted with a methyl group at the 3-position.

Alternatively, the order of these coupling steps may be reversed (Scheme 2). A substituted halocinnamic acid S (e.g. 3-chloro-2-nitrocinnamic acid or the like) may he coupled with a primary or secondary amine (e.g. N-acetylpipcrazine OT the like) as described above to give the corresponding amide 6. The halo-group can then be displaced with a substituted thiophenol in the presence of base to provide the product 7.


A number of the compounds described herein may be prepared from intermediate benzylic alcohols like 8 (Scheme 3) Activation of the alcohol moiety (for example, using phosphorus tribromide or methanesulfonyl chloride and lithium halide in dimethylformamide) and displacement with a primary or secondary amine (e.g. morpholine. N-formylpiperazine or the like) provides analogs with structures related to 9. Alternatively the alcohol may be oxidized (for example using TPAP or PCC or the like) to give aldehyde lfl.

Cinnamides like 13 may be prepared from halo-substituted derivatives 11 by palladium-mediated coupling (e.g. using tetrakis (o-tolyl phosphine) palladium (0), Pd,(dba)„ or the like] with acrylarnidc derivatives 12 (Scheme 4). In similar manner, anilino-cinnamidcs like 16 can be prepared by palladium-mediated coupling of amines 15 with halo-cinnamides 14.


In some cases, functional groups on the aromatic rings can be modified to produce new analogs (Scheme 5). For example, a nitro group in compounds like 17 may be reduced [for example, with tin(ll) chloride, or by catalytic hydrogcnation. or the like) to the corresponding amine 18. This amine may then itself be converted to a halogen, for example by diazotization using nitrous acid or t-butyl nitrite in the presence of a metal halide salt like cupric bromide, providing analog 19.

It is also possible to assemble cinnamide-stibstituted diary! sulfides in a "reverse" sense (Scheme 6). Thus, for example, compound 20, prepared as described in Scheme 1, may be deprolected by treatment with base (e.g. potassium t-butoxide or the like) to provide thiolatc anion 21, which may be reacted with an activated

haloarene (e.g. 2,3-diehlorobenzaldehyde, 3-chioro,4-fluorobenzaldehyde or the like) to provide the corresponding product 22. Alternatively, this same thiolate anion may Decoupled withunactivated aryl hal ides (e.g. aryl bromide or Aryl iodides) using a metal-catalyzed Ullman coupling procedure (for example, using a palladium or nickel catalyst) to give product 23.
A further method for producing diarylsulfide cinnamides is shown in Scheme 7, wherein the diaryl sulfide is formed through coupling of a suitably protected aryl thiol 28 to an activated cinnamale ester 27. Substituted phenol 24 may be brominated to give bromophenol 25. Heck-type coupling of bromide 25 with an appropriate olefinic substrate, for example methyl acrylate, is effected with palladium catalysis, leading to the cinnamate ester 26. The phenol is then activated towards further reaction, for example by conversion to the corresponding triflate 27 under standard conditions. The required protected thiol 28 may be prepared by the method of XXX {Tetrahedron Lett. 1994,35. 3221-3224), by coupling an aryl halide or triflate with triisopropylsilyi thiol under palladium catalysis. The two partners 27 and 28 are then reacted in the presence of a fluoride source, for example cesium fluoride, to provide the diarylsulfide cinnamate 29. Hydrolysis is accomplished by basic media, such as lithium or sodium hydroxide in water-THF, and the resulting acid 30 is coupled to amines under standard amide-bond forming conditions (for example, EDC/HOBt) IQ produce the amides 31.


A method for preparing cinnamides bearing two a^lthio groups is outlined in Scheme 8. Commercially available difiuoro cinnamic acid 32 was coupled with an amine, using standard conditions, and this derived amide 33 was reacted with excess aryl thiol to provide the bis-sulfide 34.

Compounds which contain trifluoromethyl groups on the cinnamide-portion of inhibitors were made by the method shown in Scheme 9. According to the method of

XXX (Ref), Diels-Alder reaction between l,I,l,4,4.4-hexafluoro-2-butyne and 2-methylfuran led to bicyclic ether 35, whiuh was rearranged with Lewis acid (for example, baron trifluoridc etherate) to the phenol 36. The methyl group is then converted to the corresponding aldehyde 37 by bromination followed by reaction with dimethylsulfoxide. Using the analogous procedures described for Scheme 1 above, the pheno! was activated and condensed with thiols under basic conditions lo afford diarylsulfide aldehydes 38, and further converted to cinnamides 39 by the previously described procedures.
i
Cinnamides bearing more complex substituted piperidine amides can be produced by the methods outlined in Scheme 10 and 11. Cinnamic acids 40 are coupled to spiro-hydantoin piperidine 41, and the derived amide 42 is first reacted with an activating reagent (for example di-tert-butyl dicarbonate), and then
! hydrolyzed to the amino acid 43. The derived amino group may then be reacted further, for example with acid anhydrides or acid chlorides, to produce amides 44.


Further derivatives of piperidine amides can be obtained by coupling of piperidinone 45 with cinnamic acids 40, as shown in Scheme 11. Standard coupling conditions lead to amide 4fi, which is first reduced to the corresponding alcohol, then hydrolyzed to afford hydroxy acid 47.


Also included in this invention are compounds derived from coupling of amines, or amino acid derivatives (such as a-amino esters) to the carboxylic acid group of cinnamides 48, using standard coupling and hydrolysis methods, as outlined in Scheme 12. Thus, amides 49 are produced directly from amine coupling reactions. Amino acid esters are coupled lo 48, and the derived esters are hydrolyzed to the corresponding acids 50.

Inhibitors bearing substituted piperazine (or homopiperazinc) cinnamides may be produced by the methods described in Scheme ] 3. The methods described may be utilized to produce piperazine amide 51. Secondary amine 51 then serves as educt for preparing amides 52, through standard coupling reactions. Alternatively, 51 may be converted to tertiary amines 53. through standard reductive alkylation methods (for example, condensation with an aldehyde in the presence of a reducing agent such as sodium triacetoxyborobydride).


A process for preparing analogs with amino substitutions of the aryl portion of the sulfides is illustrated in Scheme 14. The intermediate triflate 27 is reacted with halo-substituted thiophenols 54 (X = Dt, CI, OTf. OTs) under basic catalysis, to provide the sulfide derivative 55. The halogen or activated hydroxy! is then substituted with an amine, using the method of Buchwald (Old, D. W.; Wolfe, J. P.; Buchwald, S. L. J. Am. Cheat. Soc. 1998,120. 9722-9723). Similar transition-metal catalyzed reactions may be applied, for example, the method of Hartwiy {Hamann, B. C; Hartwig. J. F. J. Am. Chem. Soc. 1998,120. 7369-7370). The NR3R, group may constitute a cyclic or acyclic group, optionally substituted with additional functionalities that may enhance the activities of the compounds, and that further synthetic transformations familiar to those skilled in the art may he applied. For instance, ester groups may be hydrolyzed to the corresponding carboxylic acids or amides. The derived anilino sulfides may then be processed as described above lo produce the cinnamides 56.
