BACKGROUND OF THE INVENTION Field of the Invention This invention relates to novel therapeutic agents which bind to mammalian receptors and modulate their activity. More particularly, the invention relates to novel therapeutic agents that bind to and modulate the in vivo activity of PPARy and RXR receptors in mammals by acting as multi-binding compounds. The therapeutic agents or multi-binding compounds described herein comprise at least two ligands connected by a linker or linkers, wherein said ligands in their monovalent state bind to and/or are capable of modulating the activity of the PPARy and RXR receptors. The linking moiety is chosen such that the multi- binding compounds so constructed demonstrate increased biological activity as compared to the same number of individual units of the ligand or ligands. The invention also relates to methods of using such compounds, to methods of preparing such compounds and to pharmaceutical compositions containing them.

These multi-binding compounds are particularly useful in treating mammalian conditions that are mediated by the PPARy receptors targeted by the ligands, such as non-insulin dependent diabetes mellitus, cancer, including colon carcinomas and lipocarcinomas, hyperlipidemia, atherosclerosis and inflammatory

diseases such as rheumatoid arthritis and inflammatory bowel disease.

Accordingly, this invention also relates to pharmaceutical compositions comprising a pharmaceutically acceptable excipient and an effective amount of a multi-binding compound of this invention.

Publications cited herein are incorporated by reference in their entirety to the same extent as if each individual publication was specifically and individually indicated to be incorporated by reference in its entirety.

State of the Art A receptor is a biological structure with one or more binding domains that reversibly complexes with one or more ligands, where that complexation has biological consequences.

Receptors can exist entirely outside the cell (extracellular receptors), within the cell membrane (but presenting sections of the receptor to the extracellular milieu and cytosol), or entirely within the cell (intracellular receptors). They may also function independently of a cell (e. g., clot formation). Receptors within the cell membrane allow a cell to communicate with the space outside of its boundaries (i. e., signaling) as well as to function in the transport of molecules and ions into and out of the cell.

A ligand is a binding partner for a specific receptor or family of receptors.

A ligand may be the endogenous ligand for the receptor or alternatively may be a synthetic ligand for the receptor such as a drug, a drug candidate or a pharmacological tool.

The ligands that bind to cellular receptors may be specifically classified as follows:

1. Full agonists-ligands that when bound trigger the maximum activity seen by natural ligands; 2. Partial agonists-ligands that when bound trigger sub-maximal activity; 3. Antagonist-ligands that when bound inhibit or prevent the activity arising from a natural ligand binding to the receptor. Antagonists may be of the surmountable class (results in the parallel displacement of the dose-response curve of the agonist to the right in a dose dependent fashion without reducing the maximal response for the agonist) or insurmountable class (results in depression of the maximal response for a given agonist with or without the parallel shift); 4. Inverse antagonist-ligands that when bound decrease the basal activity of the unbound receptor (if any).

There are four fundamental measurable properties that pertain to the interaction of a ligand with its receptor: 1) the affinity of the ligand for the receptor, which relates to the energetics of the binding; 2) the efficacy of the ligand for the receptor, which relates to the functional downstream activity of the ligand; 3) the kinetics of the ligand for the receptor, which defines the onset of action and the duration of action; and 4) the desensitization of the receptor for the ligand.

With regard to the ligand, it is the combination of these properties that provides the foundation for defining the nature of the functional response. Thus, an activating ligand (or agonist) has affinity for the receptor and downstream efficacy. In contrast, an inhibiting ligand (antagonist) has affinity for the receptor but no efficacy.

Selectivity defines the ratios of affinities or the ratios of efficacies of a given ligand compared across two receptors. It is the selectivity of a specific drug that provides the required biological profile.

Current drugs (ligands) targeting PPARy receptors have clinical shortcomings identified by one or more of low efficacy, low affinity, poor safety profile, lack of selectivity or overselectivity for the intended receptor, and suboptimal duration of action and onset of action. Accordingly, it would be beneficial to develop ligands that have improved affinity, efficacy, selectivity, onset of action and duration of action.

Affinity of ligand for target receptor An increase in ligand affinity to the target receptor may contribute to reducing the dose of ligand required to induce the desired therapeutic effect. A reduction in ligand affinity will remove activity and may contribute to the selectivity profile for a ligand.

Efficacy of ligand at a target receptor (functional effect An increased ligand efficacy at a target receptor can lead to a reduction in the dose required to mediate the desired therapeutic effect. This increase in efficacy may arise from an improved positive functional response of the ligand or a change from a partial to full agonist profile. Reduced efficacy of a full agonist to a partial agonist may provide clinical benefit by modulating the biological response.

Selectivity of ligand compared across receptor subtypes An increase in the selectivity of the ligand across receptor subtypes requires that the affinity or efficacy of the ligand at other receptors is reduced relative to the desired receptor.

Onset of Action More rapid onset of action of the ligand to effect a biological response is often preferred.

Duration of Action An increased duration of action of the ligand to effect a biological response may be preferred. For example ß2 adrenergic agonists such as albuterol have a relatively short duration of action of approximately 3-4 hours and an increase in duration of action would simplify the dosing regimen required to administer this drug (ligand).

The nuclear receptor superfamily comprises a number of ligand-activated transcription factors which control a wide range of biological processes involving gene expression such as differentiation, development and homeostasis. This superfamily of receptors includes the estrogen (ER), thyroid (TR), progesterone (PR) and retinoid receptors (RXR, RAR), in addition to the peroxisome proliferator-activated receptors (PPARa, PPAR5, and PPARy). These receptors possess the common structural motifs of an amino-terminal ligand independent transactivation domain, a central DNA binding domain, and a carboxy-terminal ligand-binding domain (LBD). The central DNA binding domain recognizes a specific sequence of DNA, termed generically the Hormone Response Element (HRE). Activation of these receptors is associated with the binding of specific small molecule ligands to the LBD site, which then correlates with the association of the DNA binding domain with an HRE site on DNA, leading to transcriptional events. There is a body of crystallographic and biological evidence indicating that this class of receptors functions as a homo-or hetero-dimeric complex. For a review, see Cell Vol 83 (1995) 835-839.

The peroxisome proliferator-activated receptor gamma (PPARy) is found principally in adipocytes and forms a functional heterodimer with the retinoid X receptor (RXR). Receptor dimerization has been shown to be required for functional gene expression via activation of the nuclear receptors. Activation of the PPARy-RXR heterodimer by PPARy-specific or RXR-specific ligands in preadipocytes promotes gene transcription and differentiation to adipocytes. Thus, either ligand can activate the heterodimeric receptor complex. Administration of PPARy ligands or RXR ligands to mammals with hyperglycemia, hyperinsulinemia, or hypertriglyceridemia leads to a reduction of blood glucose, serum triglycerides and serum non-esterified fatty acids, in addition to the differentiation of adipocytes. Additionally, the co-administration of a PPARy ligand and an RXR ligand to cells over-expressing the PPARy-RXR heterodimer is synergistic in activating gene transcription. The coadministration of a PPARy ligand and an RXR ligand to a hyperglycemic mammal leads to an enhancement of the glucose-and lipid-lowering effects compared to administration of either ligand alone. See Nature Vol 386 (1197) 407-410 and Mol. and Cell Biol. Vol 18 (1998) 3483-3494.

Accordingly, novel ligands having desired potency and therapeutic effect for the PPARy receptor would be particularly desirable in order to further increase insulin sensitivity, especially in the case of non-insulin dependent diabetes mellitus (NIDDM) in mammalian patients. Such novel ligands would preferably achieve the desired potency and therapeutic effect by modulating one or more of the ligand's properties as to efficacy, affinity, safety profile, selectivity, duration of action and/or onset of action. This may have advantages in the effects on other disease states as well, such as certain types of cancer, hyperlipidemia, atherosclerosis and inflammatory diseases.

DETAILED DESCRIPTION OF THE INVENTION Ligand (drug) interactions with cellular receptors are controlled by molecular interaction/recognition between the ligand and the receptor. In turn, such interaction can result in modulation or disruption of the biological processes/functions of these receptors and, in some cases, leads to cell death.

Accordingly, when cellular receptors mediate mammalian pathologic conditions, interactions of the ligand with the cellular receptor can be used to treat these conditions. Of particular interest are mammalian PPARy and RXR receptors which are known to affect insulin sensitivity, serum triglyceride levels and free fatty acids, as well as other important functions controlled by gene expression. As noted above, this invention is directed, in part, to multi-binding compounds that bind PPARy and RXR receptors.

The"affinity"and"specificity"of the PPARy and RXR receptors and ligands thereto are dependent upon the complementarity of molecular binding surfaces and the energetic costs of complexation."Affinity"is sometimes quantified by the equilibrium constant of complex formation. Specificity relates to the difference in affinity between the same ligand binding to different ligand binding sites on the cellular receptor.

The multi-binding compounds of this invention are capable of acting as multi-binding agents and the surprising activity of these compounds arises at least in part from their ability to bind in a multivalent manner with mammalian PPARy and optionally RXR receptors. Multivalent binding interactions are characterized by the concurrent interaction of multiple ligands with multiple ligand binding sites

on one or more PPARy and optionally RXR receptors. Multivalent interactions differ from collections of individual monovalent interactions by imparting enhanced biological and/or therapeutic effect. Examples of multivalent binding interactions (e. g., trivalent) relative to monovalent binding interactions are shown below: Just as multivalent binding can amplify binding affinities, it can also amplify differences in binding affinities, resulting in enhanced binding specificity as well as affinity.

The term"optional"or"optionally"means that the subsequently described event, circumstance or substituent may or may not occur, and that the description includes instances where said event or circumstance occurs and instances where it does not.

As used herein, the terms"inert organic solvent"or"inert solvent"mean a solvent inert under the conditions of the reaction being described in conjunction therewith [including, for example, benzene, toluene, acetonitrile, tetrahydrofuran ("THF"), dimethylformamide ("DMF"), chloroform (CHCl3), methylene chloride (or dichloromethane or"CH2Cl2"), diethyl ether, ethyl acetate, acetone, methylethyl ketone, methanol, ethanol, propanol, isopropanol, tert-butanol, dioxane, pyridine, and the like]. Unless specified to the contrary, the solvents used in the reactions of the present invention are inert solvents.

The"PPARy receptor"is a receptor and plays a role in the mechanisms of insulin sensitivity. PPARy receptors are located primarily in adipose tissues throughout the body. The PPARy receptor forms a heterodimer with the RXR receptor. Together, they act to affect insulin sensitivity in the cell, particularly as results from NIDDM, and may affect inflammatory diseases such as rheumatoid

arthritis and inflammatory bowel disease, cancer such as colon carcinoma and lipocarcinoma, hyperlipidemia and arterioclerosis.

It should be recognized that the PPARy and RXR receptors that participate in biological multivalent binding interactions are constrained to varying degrees by their intra-and intermolecular associations (e. g. cellular receptors may be covalently joined in a single structure, noncovalently associated in a multimeric structure, embedded in a membrane or polymeric matrix and so on) and therefore have less translational and rotational freedom than if the same cellular receptors were present as monomers in solution.

The term"library"refers to at least 3, preferably from 102 to 109 and more preferably from 102 to 104 multimeric compounds. Preferably, these compounds are prepared as a multiplicity of compounds in a single solution or reaction mixture which permits facile synthesis thereof. In one embodiment, the library of multimeric compounds can be directly assayed for multibinding properties. In another embodiment, each member of the library of multimeric compounds is first isolated and, optionally, characterized. This member is then assayed for multibinding properties.

The term"collection"refers to a set of multimeric compounds which are prepared either sequentially or concurrently (e. g., combinatorially). The collection comprises at least 2 members; preferably from 2 to 109 members and still more preferably from 10 to 104 members.

The term"ligand binding site"as used herein denotes the site on the PPARy or RXR receptor that recognizes a ligand domain and provides a binding partner for that ligand. The ligand binding site may be defined by monomeric or multimeric structures. This interaction may be capable of producing a unique

biological effect, for example agonism, antagonism, modulatory effect and the like or may maintain an ongoing biological event.

"PPARy Ligand"as used herein denotes a compound that is a binding partner for the PPARY receptor and is bound thereto by complementarity. The specific region or regions of the ligand that is (are) recognized by the PPARY receptor is designated as the"PPAR ligand domain". A'igand may be either capable of binding to a receptor by itself, or may require the presence of one or more non-ligand components for binding (e. g., Ca+2, Mg+2 or a water molecule).

"RXR Ligand"as used herein denotes a compound that is a binding partner for the RXR receptor and is bound thereto by complementarity. The specific region or regions of the ligand that is (are) recognized by the RXR receptor is designated as the"RXR ligand domain". A ligand may be either capable of binding to a receptor by itself, or may require the presence of one or more non- ligand components for binding (e. g., Ca+2, Mg+2 or a water molecule).

It is further understood that the term"PPARy ligand"or"RXR ligand"is not intended to be limited to compounds known to be useful as PPARY and RXR receptor binding compounds (e. g., known drugs). It should also be understood that portions of the ligand structure that are not essential for specific molecular recognition and binding activity may be varied substantially, replaced with unrelated structures and, in some cases, omitted entirely without affecting the binding interaction. The primary requirement for the ligand is that it has a ligand domain as defined above. Those skilled in the art will understand that the term ligand can equally apply to a molecule that is not normally associated with PPARY and RXR cellular receptor binding properties. In addition, it should be noted that ligands that exhibit marginal activity or lack useful activity as monomers can be

highly active as multivalent compounds because of the benefits conferred by multi- valency. The only requirement for a ligand is that it has a ligand binding domain as defined above.

A"multimeric compound"refers to a compound that is capable of multivalency as defined below, and which has 2 to 10 ligands covalently bound to one or more linkers which may be the same or different. The compound may or may not possess multibinding properties. At least one of the ligands comprises a ligand domain capable of binding to one or more PPARy receptors, and optionally RXR receptors. The multi-binding compound provides a biological and/or therapeutic effect greater than the aggregate of unlinked ligands equivalent thereto which may be the same or different which unlinked ligands comprise a ligand domain capable of binding to one or more PPARy receptors, and optionally RXR receptors. That is to say that the biological and/or therapeutic effect of the PPARy and/or RXR binding ligands attached to the multi-binding compound is greater than that achieved by the same amount of unlinked PPARy and/or RXR ligands made available for binding to the ligand binding sites.

The phrase"increased biological or therapeutic effect"includes, for example increased affinity for a target, increased specificity for a target, increased selectivity for a target, increased potency, increased efficacy, decreased toxicity, improved duration of action, decreased side effects, increased therapeutic index, improved bioavailability, improved pharmacokinetics, improved activity spectrum, and the like. The multi-binding compounds of this invention will exhibit at least one and preferably more than one of the above mentioned effects.

"Uni-valency"as used herein refers to a single binding interaction between one ligand as defined herein with one ligand binding site as defined herein. It should be noted that a molecule having multiple copies of a ligand (or ligands) exhibits uni-valency when only one ligand is interacting with a ligand binding site.

Examples of a univalent interaction are depicted below.

"Multi-valency"as used herein refers to the concurrent binding of from 2 to 10 linked ligands (which may be the same or different) and two or more corresponding ligand binding sites on the receptors which receptors may be the same or different.

For example, two ligands connected by a linker that bind concurrently to two ligand binding sites would be considered as bi-valency ; three ligands thus connected would be an example of tri-valency. An example of tri-valency illustrating a multi-binding agent bearing three ligands versus a monovalent binding interaction is shown below: univalent interaction trivalent interaction

It should be understood that all compounds that contain multiple copies of a ligand attached to a linker do not necessarily exhibit the phenomena of multi- valency, i. e., that the biological and/or therapeutic effect of the multi-binding agent is greater than the sum of the aggregate of unlinked ligands made available to the ligand binding site. For multivalency to occur, the ligands that are connected by a linker have to be presented to their receptors by the linker in a specific manner in order to bring about the desired ligand-orienting result, and thus produce a multi-binding agent.

"Potency"as used herein refers to the minimum concentration at which a ligand is able to achieve a desirable biological or therapeutic effect. The potency of a ligand is typically proportional to its affinity for its ligand binding site. In some cases the potency may be non-linearly correlated with its affinity. In comparing the potency of two drugs, e. g., a multi-binding agent and the aggregate of its unlinked ligand, the dose-response curve of each is determined under identical test conditions (e. g. an in vitro or in vivo assay, in an appropriate animal model such as a human patient). The finding that the multi-binding agent produces an equivalent biological or therapeutic effect at a lower concentration than the aggregate unlinked ligand (e. g. on a per weight, per mole or per ligand basis) is indicative of enhanced potency.

"Selectivity"or"specificity"is a measure of the binding preferences of a ligand for different ligand binding sites. The selectivity of a ligand with respect to its target ligand binding site relative to another ligand binding site is given by the ratio of the respective values of Kd (i. e., the dissociation constants for each ligand- receptor complex) or in cases where a biological effect is observed below the Kd, the ratio of the respective EC50 s (i. e., the concentrations that produce 50% of the maximum response for the ligand interacting with the two distinct ligand binding sites).

The terms"agonism"and"antagonism"are well known in the art. The term"modulatory effect"refers to the ability of the ligand to change the activity of an agonist or antagonist through binding to a ligand binding site.

The term"partial agonist"refers to a receptor agonist which cannot fully elicit a maximal response when it binds to the receptor, no matter how high the concentration of the partial agonist. A partial agonist is able to combine with the receptor, but the full effect of the binding is not elicited. This term is well known in the art and a discussion of it may be found in Textbook of Receptor Pharmacology, ch 1.4, J. Foreman and T. Johansen eds., CRC Press, 1996.

The term"treatment"refers to the treatment of diabetes, in particular insulin sensitivity in a mammal, particularly a human, and includes: (i) increasing insulin sensitivity in a subject; (ii) lowering insulin, triglyceride and free fatty acid serum levels; or (iii) relieving or reducing insulin resistance, e. g., relieving or reducing the intensity and/or severity of the insulin resistance.

The term"therapeutically effective amount"refers to that amount of multi- binding compound which is sufficient to effect treatment, as defined above, when administered to a mammal in need of such treatment. The therapeutically effective amount will vary depending upon the subject and disease condition being treated, the weight and age of the subject, the severity of the disease condition, the manner of administration and the like, which can readily be determined by one of ordinary skill in the art.

The term"linker,"identified where appropriate by the symbol"X", refers to a group or groups that covalently link (s) from 2 to 10 ligands (as identified above) in a manner that provides for a compound capable of multi-valency when in

the presence of at least one cellular receptor having 2 or more ligand binding sites.

The linker is a ligand-orienting entity which may be chiral or achiral that permits attachment of multiple copies of a ligand (which may be the same or different) thereto. In some cases the linker may be biologically active. The term linker does not, however, extend to cover solid inert supports such as beads, glass particles, fibers and the like. But it is to be understood that the multi-binding compounds of this invention can be attached to a solid support if desired, for example, for use in separation and purification processes and for similar applications.

The ligands and linkers which comprise the multibinding agents of the invention and the multibinding compounds themselves may have various stereoisomeric forms, including enantiomers and diastereomers. It is to be understood that the invention contemplates all possible stereoisomeric forms of multibinding compounds, and mixtures thereof.

The extent to which multivalent binding is realized depends upon the efficiency with which the linker or linkers that joins the ligands presents them to their ligand binding sites on one or more receptors. Beyond presenting ligands for multivalent interactions with ligand binding sites, the linker spatially constrains these interactions to occur within dimensions defined by the linker. Thus the structural features of the linker (valency, geometry, orientation, size, flexibility, chemical composition) are features of multivalent compounds that play an important role in determining their activities.

Methodology The linker, when covalently attached to the ligands, provides a biocompatible, substantially non-immunogenic multi-binding compound of this invention. The biological activity of the multi-binding compound is highly sensitive to the valency, geometry, composition, size, flexibility or rigidity, etc. of

the linker as well as the presence or absence of anionic or cationic charge, the relative hydrophobicity/hydrophilicity of the linker, and the like on the linker. In general, the linker may be chosen from any organic molecule construct that orients two or more ligands to the receptors to permit multi-valency. In this regard, the linker can be considered as a"framework"on which the ligands are arranged in order to bring about the desired ligand-orienting result, and thus produce a multi- binding compound.

Ancillary groups which enhance the water solubility/hydrophilicity of the linker and, accordingly, the resulting multi-binding compounds are useful in practicing this invention. Thus, it is within the scope of the present invention to use ancillary groups such as, for example, poly (ethylene glycols), alcohols, polyols, (e. g., glycerin, glycerol propoxylate, saccharides, including mono-, oligo-and polysaccharides, etc.) carboxylates, polycarboxylates, (e. g., polyglutamic acid, polyacrylic acid, etc.), amines, polyamines, (e. g., polylycine, poly (ethyleneimine), and the like) to enhance the water solubility and/or hydrophilicity of the multi-binding compounds of this invention. In preferred embodiments, the ancillary group used to improve water solubility/hydrophilicity will be a polyether. In particularly preferred embodiments, the ancillary group will be a poly (ethylene glycol).

The incorporation of lipophilic ancillary groups within the structure of the linker to enhance the lipophilicity and/or hydrophobicity of the multi-binding compounds described herein is within the scope of this invention. Lipophilic groups useful with the linkers of this invention include, by way of example only, aryl and heteroaryl groups which, as above, may be either unsubstituted or substituted with other groups, but are at least substituted with a group which allows their covalent attachment to the linker. Other lipophilic groups useful with

the linkers of this invention include fatty acid derivatives which do not form bilayers in aqueous medium until higher concentrations are reached.

Also within the scope of this invention is the use of ancillary groups which result in the multi-binding compound being incorporated into a vesicle such as a liposome or a micelle. The term"lipid"refers to any fatty acid derivative that is capable of forming a bilayer such that a hydrophobic portion of the lipid material orients toward the bilayer while a hydrophilic portion orients toward the aqueous phase. Hydrophilic characteristics derive from the presence of phosphato, carboxylic, sulfato, amino, sulfhydryl, nitro and other like groups well known in the art. Hydrophobicity could be conferred by the inclusion of groups that include, but are not limited to, long chain saturated and unsaturated aliphatic hydrocarbon groups of up to 20 carbon atoms and such groups substituted by one or more aryl, heteroaryl, cycloalkyl, and/or heterocyclic group (s). Preferred lipids are phosphoglycerides and sphingolipids, representative examples of which include phosphatidylcholine, phosphatidylethanolamine, phosphatidylserine, phosphatidylinositol, phosphatidic acid, palmitoyleoyl phosphatidylcholine, lysophosphatidylcholine, lysophosphatidyl-ethanolamine, dipalmitoylphosphatidylcholine, dioleoylphosphatidylcholine, distearoyl- phosphatidylcholine or dilinoleoylphosphatidylcholine could be used. Other compounds lacking phosphorus, such as sphingolipid and glycosphingolipid families are also within the group designated as lipid. Additionally, the amphipathic lipids described above may be mixed with other lipids including triglycerides and sterols.

The flexibility of the linker can be manipulated by the inclusion of ancillary groups which are bulky and/or rigid. The presence of bulky or rigid groups can hinder free rotation about bonds in the linker or bonds between the linker and the ancillary group (s) or bonds between the linker and the functional groups. Rigid

groups can include, for example, those groups whose conformational lability is restrained by the presence of rings and/or multiple bonds, for example, aryl, heteroaryl, cycloalkyl and heterocyclic groups. Other groups which can impart rigidity include polypeptide groups such as oligo-or polyproline chains.

Rigidity can also be imparted electrostatically. Thus, if the ancillary groups are either positively or negatively charged, the similarly charged ancillary groups will force the presenter linker into a configuration affording the maximum distance between each of the like charges. The energetic cost of bringing the like- charged groups closer to each other will tend to hold the linker in a configuration that maintains the separation between the like-charged ancillary groups. Further ancillary groups bearing opposite charges will tend to be attracted to their oppositely charged counterparts and potentially may enter into both inter-and intramolecular ionic bonds. This non-covalent mechanism will tend to hold the linker into a conformation which allows bonding between the oppositely charged groups. The addition of ancillary groups which are charged, or alternatively, bear a latent charge when deprotected, following the addition to the linker, include deprotectation of a carboxyl, hydroxyl, thiol or amino protecting group, by a change in pH, oxidation, reduction or other mechanisms known to those skilled in the art, is within the scope of this invention.

Bulky groups can include, for example, large atoms, ions (e. g., iodine, sulfur, metal ions, etc.) or groups containing large atoms, polycyclic groups, including aromatic groups, non-aromatic groups and structures incorporating one or more carbon-carbon multiple bonds (i. e., alkenes and alkynes). Bulky groups can also include oligomers and polymers which are branched-or straight-chain species. Species that are branched are expected to increase the rigidity of the structure more per unit molecular weight gain than are straight-chain species.

In preferred embodiments, rigidity is imparted by the presence of cyclic groups (e. g., aryl, heteroaryl, cycloalkyl, heterocyclic, etc.). In still further preferred embodiments, the ring is an aryl group such as, for example, phenyl or naphthyl. In other preferred embodiments, the linker comprises one or more six- membered rings or crown groups which, while not rigid, retain the conformation of the linker through conformational entropy.

In view of the above, it is apparent that the appropriate selection of a linker group providing suitable orientation, entropy and physico-chemical properties is well within the skill of the art. Eliminating or reducing antigenicity of the multi- binding compounds described herein is also within the scope of this invention.

As explained above, the multi-binding compounds described herein comprise 2-10 ligands for PPARy and/or RXR, so long as at least one PPARy ligand is present, attached to a linker that links the ligands in such a manner that they are presented to the PPARy/RXR receptor complex for multivalent interactions. The linker spatially constrains these interactions to occur within dimensions defined by the linker, thus greatly increasing biological activity of the multi-binding compound as compared to the same number of ligands used in mono-binding form.

The multi-binding compounds of this invention are preferably represented by the empirical formula (L) p (X) q where L, X, p and q are as defined above. This is intended to include the several ways in which the ligands can be linked together in order to achieve the objective of multi-valency, and a more detailed explanation is described below.

As noted previously, the linker may be considered as a framework to which ligands are attached. Thus, it should be recognized that the ligands can be

attached at any suitable position on this framework, for example, at the termini of a linear chain or at any intermediate position.

The simplest and most preferred multi-binding compound is a bivalent compound which can be represented as L-X-L, where L is a ligand and is the same or different and X is the linker. A trivalent compound could also be represented in a linear fashion, i. e., as a sequence of repeated units L-X-L-X-L, in which L is a ligand and is the same or different at each occurrence, as can X. However, a trimer can also be a multi-binding compound comprising three ligands attached to a central core, and thus represented as (L) 3X, where the linker X could include, for example, an aryl or cycloalkyl group. Tetravalent compounds can be represented as, for example, in a linear array: L-X-L-X-L-X-L or in a tetrahedral array:

where X and L are as defined herein.

The same considerations apply to higher multibinding compounds of this invention containing 5-10 ligands. However, for multibinding agents attached to a central linker such as aryl or cycloalkyl, there is a self-evident constraint that there must be sufficient attachment sites on the linker to accommodate the number of ligands present; for example, a benzene ring could not directly accommodate more than 6 ligands, whereas a multi-ring linker (e. g., biphenyl) could accommodate a larger number of ligands.

Certain of the above described compounds may alternatively be represented as cyclic chains of the form:

and variants thereof.

All of the above variations are intended to be within the scope of the invention defined by the formula (L) p (X) q.

In view of the above description of the linker, it is understood that the term "linker"when used in combination with the term"multibinding compound" includes both a covalently contiguous single linker (e. g., L-X-L) and multiple covalently non-contiguous linkers (L-X-L-X-L) within the multibinding compound.

Preparation of Multibinding Compounds The multibinding compounds of this invention can be prepared from readily available starting materials using the following general methods and procedures. It will be appreciated that where typical or preferred process conditions (i. e., reaction temperatures, times, mole ratios of reactants, solvents, pressures, etc.) are given, other process conditions can also be used unless otherwise stated. Optimum reaction conditions may vary with the particular reactants or solvent used, but such conditions can be determined by one skilled in the art by routine optimization procedures.

Additionally, as will be apparent to those skilled in the art, conventional protecting groups may be necessary to prevent certain functional groups from undergoing undesired reactions. The choice of a suitable protecting group for a particular functional group as well as suitable conditions for protection and deprotection are well known in the art. For example, numerous protecting groups, and their introduction and removal, are described in T. W. Greene and G. M.

Suitable RXR ligands for use in the invention may include known RXR ligands such as the following: RXR Llgands <BR> <BR> Panretin Tazoretene Tagretin

Derivatives of RXR ligands may also be used in preparation of the invention. Such derivatives may be selected from one or more of the following formulas II-IV : wherein X, X1 and X2 are independently selected from the group consisting of H, OH, I, Br, Cl, F, Na, SH, O, NH, carbonyl, amide, alkyl, alkoxy, aryl, aryloxy, and alkaryl; R is aryl, substituted aryl, alkyl, substituted alkyl, heteroaryl, or substituted heteroaryl; R1 is H or alkyl ; R2 is H or alkyl ; R3 is CH2, O, or NOR4 wherein R4 is alkyl or substituted alkyl ; Q is CH or N, A is

and n is 1-10.

Other RXR and PPARy ligands and derivatives may be known to those in the art. Preferentially, RXR and PPARy ligands or derivatives thereof used in the invention are preferentially bound to only the RXR or PPARy receptor, respectively. In particular, it is preferred that the PPAR ligand or derivative thereof preferentially bind only to the PPARy receptor.

Activation of the RXR receptor with known RXR ligands can lead to modulation of the transcriptional activity of a wide variety of RXR/nuclear receptor complexes. Thus, the activation of the RXR receptor by the use of RXR ligands may potentiate many other effects within the body. Because of this lack of functional specificity, use of a modified RXR ligand as set forth above to control transcription exclusivity by the PPARy/RXR heterodimer is preferred.

Preferentially, the RXR ligands used in the invention are a derivative of known RXR ligands exhibiting more limited functionality and less independent activation of, or lower binding affinity for, other RXR/nuclear receptor complexes which are not of interest.

In contrast, many known PPARy ligands are very specific in that they bind preferentially to only the PPARy receptor. These ligands, some of which are exemplified herein, and derivatives of other known PPAR agonists selected for preferential binding to the PPAR receptor, may be used herein.

It is known that fatty acids, eicosanoids, prostaglandins and metabolites thereof activate PPARy, as do non-steroidal anti-inflammatory drugs (NSAIDS).

12,14<BR> Although fatty acids such as 15 deoxy D12, 14 PGJ2, linoleic acid, y-linolenic acid, oleic acid, stearic acid, cis-pariniaric acid, eicosopentonoic acid ad decosahexanoic acid bind well to the PPARy receptor, they are not specific to the PPARy

receptor. The NSAIDS are not specific and also may have a low affinity for the PPARy receptor. Therefore, because these compounds activate one or more of the PPAR receptors, including both PPARy and PPARa, as well as potentially other receptors, they prompt too broad a response causing potentially undesirable reactions and side effects. Therefore, these would not form acceptable ligands for the invention described herein, although derivatives thereof may be identified which would preferentially bind to the PPAR receptor ard therefore could be used in the invention described herein.

In contrast, the class of drugs known as thiazolidinediones (TZDs) are highly selective for PPARy. TZDs or"glitazones"are high-affinity agonists of PPARy. The glitazones enhance the sensitivity of target tissues to insulin while reducing serum insulin and lipid levels, as well as reducing plasma levels of free fatty acids, triglycerides and total cholesterol in mammals having Type 2 diabetes, which affects the proper storage and utilization of energy in the body in the form of glucose. NIDDM is characterized by high plasma glucose levels, insulin resistance, and insufficient insulin secretion by the p-cells of the pancreas. Drug treatment of NIDDM classically focuses on increasing insulin secretion, creating a condition of hyperinsulemia which creates a risk of heart disease. Some TZDs cause increases in plasma volume, increased adipose cell formation in bone marrow at high doses, and are known to have a hepatatoxic effect. Further some TZDs lack potency for the PPARy receptor, therefore requiring high patient doses or frequent patient dosing, and potentially leading to non-mechanism (i. e., non- PPARy binding) related side effects or toxicities. Diabetes Vol. 47, (1998) 507- 514. Therefore, although TZDs may be used as ligands for the invention described herein, derivatives thereof may be desired.

Further herein, the PPARy ligand or ligand derivatives suitable for use in the invention A-K are referred to as L 1-L 11, and the RXR ligands or derivatives thereof II-IV are referred to as L12-14.

Combinatorial Libraries Combinatorial approaches for identifying multimeric compounds which possess multibinding properties will now be discussed.

Specifically, factors such as the proper juxtaposition of the individual ligands of a multibinding compound with respect to the relevant array of binding sites on a target or targets is important in optimizing the interaction of the multibinding compound with its target (s) and to maximize the biological advantage through multivalency. One approach is to identify a library of candidate multibinding compounds with properties spanning the multibinding parameters that are relevant for a particular target. These parameters include: (1) the identity of ligand (s), (2) the orientation of ligands, (3) the valency of the construct, (4) linker length, (5) linker geometry, (6) linker physical properties, and (7) linker chemical functional groups.

Libraries of multimeric compounds potentially possessing multibinding properties (i. e., candidate multibinding compounds) and comprising a multiplicity of such variables are prepared and these libraries are then evaluated via conventional assays corresponding to the ligand selected and the multibinding parameters desired. Considerations relevant to each of these variables are set forth below.

Selection of ligand (s ! A single ligand or set of ligands is (are) selected for incorporation into the libraries of candidate multibinding compounds which library is directed against a

particular biological target or targets. The only requirement for the ligands chosen is that they are capable of interacting with the selected target (s). Thus, ligands may be known drugs, modified forms of known drugs, substructures of known drugs or substrates of modified forms of known drugs (which are competent to interact with the target), or other compounds. Ligands are preferably chosen based on known favorable properties that may be projected to be carried over to or amplified in multibinding forms. Favorable properties include demonstrated safety and efficacy in human patients, ability to increase insulin sensitivity, ability to lower serum triglyceride, cholesterol and/or fatty acid levels, etc. However, it is crucial to note that ligands which display an unfavorable property from among the previous list may obtain a more favorable property through the process of multibinding compound formation; i. e., ligands should not necessarily be excluded on such a basis. For example, a ligand that is not sufficiently potent at a particular target so as to be efficacious in a human patient may become highly potent and efficacious when presented in multibinding form. A ligand that is potent and efficacious but not of utility because of a non-mechanism-related toxic side effect may have increased therapeutic index (increased potency relative to toxicity) as a multibinding compound. Compounds that exhibit short in vivo half-lives may have extended half-lives as multibinding compounds. Physical properties of ligands that limit their usefulness (e. g. poor bioavailability due to low solubility, hydrophobicity, hydrophilicity) may be rationally modulated in multibinding forms, providing compounds with physical properties consistent with the desired utility.

Orientation: selection of ligand attachment points and linking chemistry Several points are chosen on each ligand at which to attach the ligand to the linker. The selected points on the ligand/linker for attachment are functionalized to contain complementary reactive functional groups. This permits probing the effects of presenting the ligands to their receptor (s) in multiple relative

orientations, an important multibinding design parameter. The only requirement for choosing attachment points is that attaching to at least one of these points does not abrogate activity of the ligand. Such points for attachment can be identified by structural information when available. Alternatively, evaluation of ligand/target binding by nuclear magnetic resonance will permit the identification of sites non- essential for ligand/target binding. See, for example, Fesik, et al., U. S. Patent No. 5,891,643. When such structural information is not available, utilization of structure-activity relationships (SAR) for ligands will suggest positions where substantial structural variations are and are not allowed. In the absence of both structural and SAR information, a library is merely selected with multiple points of attachment to allow presentation of the ligand in multiple distinct orientations.

Subsequent evaluation of this library will indicate what positions are suitable for attachment.

It is important to emphasize that positions of attachment that do abrogate the activity of the monomeric ligand may also be advantageously included in candidate multibinding compounds in the library provided that such compounds bear at least one ligand attached in a manner which does not abrogate intrinsic activity. This selection derives from, for example, heterobivalent interactions within the context of a single target molecule. For example, consider a receptor antagonist ligand bound to its target receptor, and then consider modifying this ligand by attaching to it a second copy of the same ligand with a linker which allows the second ligand to interact with the same receptor molecule at sites proximal to the antagonist binding site, which include elements of the receptor that are not part of the formal antagonist binding site and/or elements of the matrix surrounding the receptor such as the membrane. Here, the most favorable orientation for interaction of the second ligand molecule with the receptor/matrix may be achieved by attaching it to the linker at a position which abrogates activity of the ligand at the formal antagonist binding site. Another way to consider this is

that the SAR of individual ligands within the context of a multibinding structure is often different from the SAR of those same ligands in momomeric form.

The foregoing discussion focused on bivalent interactions of dimeric compounds bearing two copies of the same ligand joined to a single linker through different attachment points, one of which may abrogate the binding/activity of the monomeric ligand. It should also be understood that bivalent advantage may also be attained with heterodimeric constructs bearing two different ligands that bind to common or different targets. For example, a PPARy receptor agonist and an RXR receptor agonist may be joined to a linker through attachment points which do not abrogate the binding affinity of the monomeric ligands for their respective receptor sites. The dimeric compound may achieve enhanced affinity for both receptors due to favorable interactions between the PPARy ligand and elements of the RXR receptor proximal to the formal RXR agonist binding site and between the RXR ligand and elements of the PPARy receptor proximal to the formal PPARy agonist binding site. Thus, the dimeric compound may be a more potent and selective agonist of insulin sensitivity and a superior therapy for NIDDM, cancer including colon carcinomas and lipocarcinomas, hyperlipedemia, arteriosclerosis and inflammatory diseases such as rheumatoid arthritis and inflammatory bowel disease.

Once the ligand attachment points have been chosen, one identifies the types of chemical linkages that are possible at those points. The most preferred types of chemical linkages are those that are compatible with the overall structure of the ligand (or protected forms of the ligand), readily and generally formed, stable and intrinsically innocuous under typical chemical and physiological conditions, and compatible with a large number of available linkers. Amide bonds, ethers, amines, carbamates, ureas, and sulfonamides are but a few examples of preferred linkages.

Linkers: spanning relevant multibinding parameters through selection of valency. linker length, linker geometry, rigidity, physical properties, and chemical functional groups In the library of linkers employed to generate the library of candidate multibinding compounds, the selection of linkers employed in this library of linkers takes into consideration the following factors.

Valency. In most instances the library of linkers is initiated with divalent linkers. The choice of ligands and proper juxtaposition of two ligands relative to their binding sites permits such molecules to exhibit target binding affinities and specificities more than sufficient to confer biological advantage. Furthermore, divalent linkers or constructs are also typically of modest size such that they retain the desirable biodistribution properties of small molecules.

Linker length. Linkers are chosen in a range of lengths to allow the spanning of a range of inter-ligand distances that encompass the distance preferable for a given divalent interaction. In some instances the preferred distance can be estimated rather precisely from high-resolution structural information of targets, typically enzymes and soluble receptor targets. In other instances where high-resolution structural information is not available, one can make use of simple models to estimate the maximum distance between binding sites either on adjacent receptors or at different locations on the same receptor. In situations where two binding sites are present on the same target (or target subunit for multisubunit targets), preferred linker distances are 2-20 A, with more preferred linker distances of 3-12 A. In situations where two binding sites reside on separate (e. g., protein) target sites, preferred linker distances are 20-100 A, with more preferred distances of 30-70 A.

Linker geometry and rigidity. The combination of ligand attachment site, linker length, linker geometry, and linker rigidity determine the possible ways in which the ligands of candidate multibinding compounds may be displayed in three dimensions and thereby presented to their binding sites. Linker geometry and rigidity are nominally determined by chemical composition and bonding pattern, which may be controlled and are systematically varied as another spanning function in a multibinding array. For example, linker geometry is varied by attaching two ligands to the ortho, meta, and para positions of a benzene ring, or in cis-or trans-arrangements at the 1,1- vs. 1,2- vs. 1,3- vs. 1,4- positions around a cyclohexane core or in cis-or trans-arrangements at a point of ethylene unsaturation. Linker rigidity is varied by controlling the number and relative energies of different conformational states possible for the linker. For example, a divalent compound bearing two ligands joined by 1,8-octyl linker has many more degrees of freedom, and is therefore less rigid than a compound in which the two ligands are attached to the 4,4' positions of a biphenyl linker.

Linker physical properties. The physical properties of linkers are nominally determined by the chemical constitution and bonding patterns of the linker, and linker physical properties impact the overall physical properties of the candidate multibinding compounds in which they are included. A range of linker compositions is typically selected to provide a range of physical properties (hydrophobicity, hydrophilicity, amphiphilicity, polarization, acidity, and basicity) in the candidate multibinding compounds. The particular choice of linker physical properties is made within the context of the physical properties of the ligands they join and, preferably, the goal is to generate molecules with favorable properties.

For example, linkers can be selected to avoid those that are too hydrophilic or too hydrophobic to be readily absorbed and/or distributed in vivo.

Linker chemical functional groups. Linker chemical functional groups are selected to be compatible with the chemistry chosen to connect linkers to the ligands and to impart the range of physical properties sufficient to span initial examination of this parameter.

Combinatorial synthesis Having chosen a set of n ligands (n being determined by the sum of the number of different attachment points for each ligand chosen) and m linkers by the process outlined above, a library of (n !) m candidate divalent multibinding compounds is prepared which spans the relevant multibinding design parameters for a particular target. For example, an array generated from two ligands, one which has two attachment points (Al, A2) and one which has three attachment points (B1, B2, B3) joined in all possible combinations provide for at least 15 possible combinations of multibinding compounds: A1-A1 A1-A2 A1-B1 A1-B2 A1-B3 A2-A2 A2-B1 A2-B2 A2-B3 B1-B1 B1-B2 B1-B3 B2-B2 B2-B3 B3-B3 When each of these combinations is joined by 10 different linkers, a library of 150 candidate multibinding compounds results.

Given the combinatorial nature of the library, common chemistries are preferably used to join the reactive functionalities on the ligands with complementary reactive functionalities on the linkers. The library therefore lends itself to efficient parallel synthetic methods. The combinatorial library can employ solid phase chemistries well known in the art wherein the ligand and/or linker is attached to a solid support. Alternatively and preferably, the combinatorial library is prepared in the solution phase. After synthesis, candidate multibinding

compounds are optionally purified before assaying for activity by, for example, chromatographic methods (e. g., HPLC).

Analysis of array by biochemical, analytical, pharmacological, and computational methods Various methods are used to characterize the properties and activities of the candidate multibinding compounds in the library to deterrrine which compounds possess multibinding properties. Physical constants such as solubility under various solvent conditions and logD/clogD values are determined. A combination of NMR spectroscopy and computational methods is used to determine low-energy conformations of the candidate multibinding compounds in fluid media. The ability of the members of the library to bind to the desired target and other targets is determined by various standard methods, which include radioligand displacement assays for receptor and ion channel targets, and kinetic inhibition analysis for many enzyme targets. In vitro efficacy, such as for receptor agonists and antagonists, ion channel blockers, and antimicrobial activity are also determined. Pharmacological data, including oral absorption, everted gut penetration, other pharmacokinetic parameters and efficacy data are determined in appropriate models. In this way, key structure-activity relationships are obtained for multibinding design parameters which are then used to direct future work.

The members of the library which exhibit multibinding properties, as defined herein, can be readily determined by conventional methods. First, those members which exhibit multibinding properties are identified by conventional methods as described above, including conventional assays (both in vitro and in vivo).

Second, ascertaining the structure of those compounds which exhibit multibinding properties can be accomplished via art recognized procedures. For

example, each member of the library can be encrypted or tagged with appropriate information allowing determination of the structure of relevant members at a later time. See, for example, Dower, et al., International Patent Application Publication No. WO 93/06121; Brenner, et al., Proc. Natl. Acad. Sci., USA, 89: 5181 (1992); Gallop, et al., U. S. Patent No. 5,846,839; each of which is incorporated herein by reference in its entirety. Alternatively, the structure of relevant multivalent compounds can also be determined from soluble and untagged libraries of candidate multivalent compounds by methods known in the art, such as those described by Hindsgaul, et al., Canadian Patent Application No. 2, 240, 325 which was published on July 11,1998. Such methods couple frontal affinity chromatography with mass spectroscopy to determine both the structure and relative binding affinities of candidate multibinding compounds to receptors.

The process set forth above for dimeric candidate multibinding compounds can, of course, be extended to trimeric candidate compounds and higher analogs thereof.

Follow-up synthesis and analysis of additional arra s Based on the information obtained through analysis of the initial library, an optional component of the process is to ascertain one or more promising multibinding"lead"compounds as defined by particular relative ligand orientations, linker lengths, linker geometries, etc. Additional libraries can then be generated around these leads to provide for further information regarding structure to activity relationships. These arrays typically bear more focused variations in linker structure to further optimize target affinity and/or activity at the target (antagonism, partial agonism, etc.), and/or alter physical properties. By iterative redesign/analysis using the novel principles of multibinding design along with classical medicinal chemistry, biochemistry, and pharmacology approaches,

one is able to prepare and identify optimal multibinding compounds that exhibit biological advantage towards their targets and as therapeutic agents.

To further elaborate upon this procedure, suitable divalent linkers include, by way of example only, those derived from dicarboxylic acids, disulfonylhalides, dialdehydes, dipseudohalides, diketones, dihalides, diisocyanates, diamines, diols, diboronates, mixtures of carboxylic acids, sulfonylhalides, aldehydes, ketones, halides, isocyanates, amines and diols. In each case, the carboxylic acid, sulfonylhalide, aldehyde, ketone, halide, isocyanate, amine and diol functional group is reacted with a complementary functionality on the ligand to form a covalent linkage. Such complementary functionality is well known in the art as illustrated in the following table, which is exemplary only: COMPLEMENTARY BINDING CHEMISTRIES First Reactive Group Second Reactive Group Linkage hydroxyl isocyanate urethane amine epoxide p-hydroxyamine sulfonyl halide amine sulfonamide carboxyl acid amine amide hydroxyl alkyl/aryl halide ether aldehyde amine/NaCNBH4 amine ketone amine/NaCNBH4 amine amine isocyanate carbamate Exemplary linkers include the following linkers identified as X-1 through X-418 as set forth below in Table 1: Diacide HO 0 OH HO OH H Ho 0 =-s 0 ° ° (tf x21 HO nf0 H X-22 HO OH OH 0 OH OH H X-24 X-2J 0 HO X-25OH OU N o 0 HOOH OH Chiral X-27O HO O HO 00 HO 0 HO p p HO 0 0 oh HO OH 0 ° X29 OH X-28X-30 0 HOSS,-, o OH OH O O fv OH 0 0 X-ii 1 0 HO HO 0yN OH 9 X-32 X-32 if zoo HO N cul OH C OH H3 C X-34 X-35 r "'"- X-33 o On o °H ° o 0 0 OH 0 HO F F OH X-, 3g 0 X36HO X-36 x-j6OH 0 0 0 ou OH OH 0 --CH3 0 S'N HO H3 0 Nv w 0 0 0 i i CH pf., r w w Chirol X-39 ° T X-40 X-41 N H3CCH3 o 0 OH HO Cl 0HO o o 0 zu X-42 X-42 OH X 44 HO0 H ',, 0 0 HO HO s 0 0s 0 OH X-45X-46 r rY' Chirol H3C OH X-47X-48 Ha 0 0 chu OH X-49 HO 0 OH OH OH N N S-S N HD p N N S-S N 0 HOF X-51 Chiral X-50 X-50 H2 N HN 0 \ HNp N p S 0 0 0 OH - pH OH X-55 HO Chirol HO Chiral X-53 X-54 0 OH OU 0 OH OH OH zu0 qHj 0 OH 3 ou o o X-58 X-56 00 OHOH HO HA HO 0D ° Chirol X60 X-590 OH Oh ou Ho nu Chiral X-61 X-62 /C C? jC 0 H3C CH3 H3C 0 0 tv tOH T 0 HO S^S/\\0 HO p H3 H3C OH Chiral 0 ° X65 ° o HOXX 64 HO OH HOzozo HO HA X-67 0 X-66 OH HO 0 0 0 0 -,OH S-N 0 HO o c ) HO Chirol N HO Chial 0 X-70 OH 0 0 HOHo OH 0 FFFFFFFF 0 HO H Chiral HA OU X-71 X-72 X-73 HO HO0 ) ===0 0 HOS 0 0 0 OH X-76 X-75 X-74 O O OHOH 0 0 H3 C HO HO X-77X-78 0 Ll) L'/77 0 HO"' OH CHj OH 0X-79 o o CH3CC NN 3 _ N CH 0 OH HOf s f N>) looH O OH Q 0 0 0 oh OH 0 HO NEZ HA OH HA 0 0 Ch ircl X-8i X-84 X-82 0 HO X-85OH CH3 0 CH3 y OH H 0 N,,..

Pharmaceutical Formulations When employed as pharmaceuticals, the compounds of the invention are usually administered in the form of pharmaceutical compositions. These compounds can be administered by a variety 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 comprise at least one active compound.

This invention also includes pharmaceutical compositions which contain, as the active ingredient, one or more of the compounds of the invention associated with pharmaceutically acceptable carriers. 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 carrier which can be in the form of a capsule, sachet, paper or other container. When the excipient serves as a diluent, it can be a solid, semi-solid, or liquid material, which acts as a vehicle, carrier 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 weight of the active compound, soft and hard gelatin capsules, suppositories, sterile injectable solutions, and sterile packaged powders.

In preparing a formulation, it may be necessary to mill the active compound to provide the appropriate particle size prior to combining with the other ingredients. If the active compound is substantially insoluble, it ordinarily 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 distribution in the formulation, e. g. about 40 mesh.

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, sterile water, syrup, and methyl cellulose. The formulations can additionally include: lubricating 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 flavoring agents. The compositions of the invention can be formulated so as to provide quick, sustained or delayed release of the active ingredient after administration to the patient by employing procedures known in the art.

The compositions are preferably formulated in a unit dosage form, each dosage containing from about 5 to about 100 mg, more usually about 10 to about 30 mg, of the active ingredient. The term"unit dosage forms"refers to physically discrete units suitable as unitary dosages for human subjects and other mammals, each unit containing a predetermined quantity of active material calculated to produce the desired therapeutic effect, in association with a suitable pharmaceutical excipient. Preferably, the compound of the invention is employed at no more than about 20 weight percent of the pharmaceutical composition, more preferably no more than about 15 weight percent, with the balance being pharmaceutically inert carrier (s).

The active compound is effective over a wide dosage range and is generally administered in a pharmaceutically effective amount. It, will be understood, however, that the amount of the compound actually administered will be determined by a physician or veterinarian, in the light of the relevant

circumstances, including the condition to be treated, the chosen route of administration, the actual compound administered and its relative activity, the age, weight, and response of the individual 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 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 dosage forms of the type described 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 action. For example, the tablet or pill can comprise an inner dosage and an outer dosage component, the latter being in the form of an envelope over the former.

The two components can be separated by an enteric layer which serves to 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 materials can be used for such enteric layers or coatings, such materials including a number of polymeric acids and mixtures of polymeric acids with such materials as shellac, cetyl alcohol, and cellulose acetate.

The liquid forms in which the novel compositions of the present invention may be incorporated for administration orally or by injection include aqueous

solutions, suitably flavored syrups, aqueous or oil suspensions, and flavored emulsions with edible oils such as corn oil, cottonseed oil, sesame oil, coconut oil, or peanut oil, as well as elixirs and similar pharmaceutical vehicles.

Compositions for inhalation or insufflation include solutions and suspensions in pharmaceutically acceptable, aqueous or organic solvents, or mixtures thereof, and powders. The liquid or solid compositions may contain suitable pharmaceutically acceptable excipients as described 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 solutions may be inhaled directly from the nebulizing device or the nebulizing device may be attached to a face mask 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 appropriate manner.

The following formulation examples illustrate representative pharmaceutical compositions of the present invention.

Formulation Example 1 Hard gelatin capsules containing the following ingredients are prepared: 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.

Formulation Example 2 A tablet formula is prepared using the ingredients below: Quantity Ingredient tablet Active Ingredient 25.0 Cellulose, microcrystalline 200.0 Colloidal silicon dioxide 10.0 Stearic acid 5.0 The components are blended and compressed to form tablets, each weighing 240 mg.

Formulation Example 3 A dry powder inhaler formulation is prepared containing the following components: Ingredient Weight % Active Ingredient 5 Lactose 95 The active ingredient is mixed with the lactose and the mixture is added to a dry powder inhaling appliance.

Formulation Example 4 Tablets, each containing 30 mg of active ingredient, are prepared as follows: Quantity Ingredient (mg/tablet) Active Ingredient 30.0 mg Starch 45.0 mg Microcrystalline cellulose 35.0 mg Polyvinylpyrrolidone (as 10% solution in sterile water) 4.0 mg Sodium carboxymethyl starch 4.5 mg Magnesium stearate 0.5 mg Talc 1.0 mg Total 120 mg

The active ingredient, starch and cellulose are passed through a No. 20 mesh U. S. sieve and mixed thoroughly. The solution of polyvinylpyrrolidone is mixed with the resultant powders, which are then passed through a 16 mesh U. S. sieve.

Another preferred formulation employed in the methods of the present invention employs transdermal delivery devices ("patches"). Such transdermal 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, herein incorporated by reference. Such patches may be constructed for continuous, pulsatile, or on demand delivery of pharmaceutical agents.

Frequently, it will be desirable or necessary to introduce the pharmaceutical composition to the brain, either directly or indirectly. Direct techniques usually involve placement of a drug delivery catheter into the host's ventricular 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.

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 primary amine groups present on the drug to render the drug more lipid soluble and amenable to transportation across the blood-brain barrier. Alternatively, the delivery of hydrophilic drugs may be enhanced by intra-arterial infusion of hypertonic solutions which can transiently open the blood-brain barrier.

Other suitable formulations for use in the present invention can be found in Remington's Pharmaceutical Sciences, Mace Publishing Company, Philadelphia, PA, 17'h Ed (1985).

Utility The multibinding agents of the present invention are useful for modulating the PPARy receptor, and, depending on the composition of the multibinding agent, also the RXR receptor. The modulation of these receptors in preadipocytes promotes gene transcription and differentiation to adipocytes. Further, modulation of these receptor sites leads gene transcription and reduction of blood glucose, serum triglycerides, and serum non-esterified fatty acids. These effects are useful in treating mammalian conditions modulated by the PPARy receptor, including non-insulin dependent diabetes mellitus, cancer, hyperlipedemia, arteriosclerosis and inflammatory diseases, for example.
