Description: COMPOUNDS FOR MODULATING THE RAGE RECEPTOR This application claims the benefit, under 35 U.S.C. § 119, of provisional application U.S. Serial No. 60/207,343, filed May 30, 2000. Field of the Invention This invention relates to compounds which are modulators of the receptor for advanced glycated end products (RAGE) and interaction with its ligands such as advanced glycated end products (AGEs), SlOO/calgranulin EN-RAGE, β-amyloid and amphoterin, for the management, treatment, control, or as an adjunct treatment of diseases caused by RAGE. Background of the Invention Incubation of proteins or lipids with aldose sugars results in nonenzymatic glycation and oxidation of amino groups on proteins to form Amadori adducts. Over time, the adducts undergo additional rearrangements, dehydrations, and cross-linking with other proteins to form complexes known as Advanced Glycosylation End Products (AGEs). Factors which promote formation of AGEs included delayed protein turnover (e.g. as in amyloidoses), accumulation of macromolecules having high lysine content, and high blood glucose levels (e.g. as in diabetes) (Hori et al, J. Biol. Chem. 270: 25752-761, (1995)). AGEs have implicated in a variety of disorders including complications associated with diabetes and normal aging. AGEs display specific and saturable binding to cell surface receptors on endothelial cells of the microvasculature, monocytes and macrophages, smooth muscle cells, mesengial cells, and neurons. The Receptor for Advanced Glycated Endproducts (RAGE) is a member of the immunoglobulin super family of cell surface molecules. The extracellular (N-teπninal) domain of RAGE includes three immunoglobulin-type regions, one V (variable) type domain followed by two C-type (constant) domains (Neeper et al, J. Biol. Chem. 267:14998-15004 (1992). A single transmembrane spanning domain and a short, highly charged cytosolic tail follow the extracellular domain. The N-terminal, extracellular domain can be isolated by proteolysis of RAGE to generate soluble RAGE (sRAGE) comprised of the N and C domains. RAGE is expressed in most tissues, and in particular, is found in cortical neurons during embryogenesis (Hori et al, J. Biol. Chem. 270:25752-761 (1995)). Increased levels of RAGE are also found in aging tissues (Schleicheret al, J. Clin. Invest. 99 (3): 457-468 (1997)), and the diabetic retina, vasculature and kidney (Schmidt et al, Nature Med. 1:1002-1004 (1995)). Activation of RAGE in different tissues and organs leads to a number of pathophysiological consequences. RAGE has been implicated in a variety of conditions including: acute and chronic inflammation (Hofmann et al, Cell 97:889-901 (1999)), the development of diabetic late complications such as increased vascular permeability (Wautier et al, J. Clin. Invest. 97:238-243 (1995)), nephropathy (Teilletet al, J. Am. Soc. Nephrol 11:1488-1497 (2000)), atherosclerosis (Nlassara et. al, The Finnish Medical Society DUODECIM, Ann. Med. 28:419-426 (1996)), and retinopathy (Hammes et al, Diabetologia 42:603-607 (1999)). RAGE has also been implicated in Alzheimer's disease (Yan et al, Nature 382: 685-691, (1996)), erectile dysfunction, and in tumor invasion and metastasis (Taguchi et al, Nature 405: 354-357, (2000)). In addition to AGEs, other compounds can bind to, and modulate RAGE. In normal development, RAGE interacts with amphoterin, a polypeptide which mediates neurite outgrowth in cultured embryonic neurons (Hori et al, 1995). RAGE has also been shown to interact with EΝ-RAGE, a protein having substantial similarity to calgranulin (Hofmann et al, Cell 97:889-901 (1999)). RAGE has also been shown to interact with β-amyloid (Yan et al, Nature 389:589-595, (1997); Yan et al, Nature 382:685-691 (1996); Yan et al, Proc. Natl.Acad. Sci, 94:5296-5301 (1997)). Binding of ligands such as AGEs, SlOO/calgranulin/EΝ-RAGE, β-amyloid, CML (Ν ε -Carboxymefhyl lysine), and amphoterin to RAGE has been shown to modify expression of a variety of genes. For example, in many cell types interaction between RAGE and its ligands generates oxidative stress, which thereby results in activation of the free radical sensitive transcription factor NF-κB, and the activation of NF-κB regulated genes, such as the cyto ines IL-lβ, TNF-α, and the like. In addition, several other regulatory pathways, such as those involving p21ras, MAP kinases, ERK1 andERK2, have been shown to be activated by binding of AGEs and other ligands to RAGE. In fact, transcription of RAGE itself is regulated at least in part by NF-κB. Thus, an ascending, and often detrimental, spiral is fueled by a positive feedback loop initiated by ligand binding. Antagonizing binding of physiological ligands to RAGE, therefore, is our target for down-regulation of the pathophysiological changes brought about by excessive concentrations of AGEs and other ligands for RAGE. Thus, there is a need for the development of compounds that antagonize binding of physiological ligands to the RAGE receptor.

Biological Assay The following assay method is utilized to identify compounds of Formula (I) which are effective in binding with RAGE, and hence useful as modulators, preferably antagonists of RAGE. This method is also described and claimed in co-pending U.S. Serial No. 09/799,152 (Attorney Docket No. TTP2000-02) filed on this date. General Assay Procedure SI 00b, β-amyloid and CML (500 ng/lOOuL/weU) in 100 mM sodium bicarbonate/sodium carbonate buffer (pH 9.8) is loaded onto the wells of aNUNC Maxisorp flat bottom 96 -well microtitre plate. The plate is incubated at 4°C overnight. The wells are aspirated and treated with 50 mM imidazole buffer saline (pH 7.2) (with lmM CaCl 2 /MgCl 2 ) containing 1% bovine serum albumin (BSA) (300 μL/well) for two h at 37 °C. The wells are aspirated and washed 3 times (400 μL/well) with 155mM NaCl pH 7.2 buffer saline and soaked 10 seconds between each wash. Test compounds are dissolved in nanopure water (concentration: 10-100 μM). DMSO may be used as co-solvent. 25 μL of test compound solution in 2% DMSO is added, along with 75 μL sRAGE (4.0 x 10 "4 mg/mL FAC) to each well and samples are incubated for 1 h at 37°C. The wells are washed 3 times with 155 mM NaCl pH 7.2 buffer saline and are soaked 10 seconds between each wash. Non-radioactive binding is performed by adding: lOμL Biotinylated goat F(ab')2 Anti-mouse IgG. (8.0 x 10 " mg/mL, FAC) lOμL Alk-phos-Sterptavidin (3 x 10 "3 mg/mL FAC) 1 OμL Polyclonal antibody for sRAGE (FAC 6.0 x 10 -3 mg/mL) to 5 mL 50mM imidazole buffer saline (pH 7.2) containing 0.2% bovine serum albumin and lmM CaCl 2 . The mixture is incubated for 30 minutes at 37° C. 100 μL complex is added to each well and incubation is allowed to proceed at rt for 1 h. Wells are washed 3 times with wash buffer and soaked 10 s between each wash. 100 μL 1 mg/mL (pNPP) in 1 M diethanolamine (pH adjusted to 9.8 with HCl) is added. Color is allowed to develop in the dark for 1 to 2 h at rt. The reaction is quenched with 10 μL of stop solution (0.5 N NaOH in 50% ethanol) and the absorbance is measured spectrophotometrically with a microplate reader at 405 nm. The following compounds of Formula 1 were synthesized according to the Schemes and tested according to the assay method described above. IC 50 (μM) of ELIS A assay represents the concentration of compound at which 50% signal has been inhibited. Compound inhibition of S-lOOb/RAGE interaction in Glioma cells by Example 1 had an IC50 of 3.3 μM. Thus, the cell based assay demonstrated effective correlation with the binding of ELISA IC 50 value (1.75 μM). NA= ELISA assay data not available The invention further provides pharmaceutical compositions comprising the RAGE modulating compounds of the invention. The term "pharmaceutical composition" is used herein to denote a composition that may be administered to a mammalian host, e.g. , orally, topically, parenterally, by inhalation spray, or rectally, in unit dosage formulations containing conventional non-toxic carriers, diluents, adjuvants, vehicles and the like. The term "parenteral" as used herein, includes subcutaneous injections, intravenous, intramuscular, intracisternal injection, or by infusion techniques. The pharmaceutical compositions containing a compound of the invention may be in a form suitable for oral use, for example, as tablets, troches, lozenges, aqueous, or oily suspensions, dispersible powders or granules, emulsions, hard or soft capsules, or syrups or elixirs. Compositions intended for oral use may be prepared according to any known method, and such compositions may contain one or more agents selected from the group consisting of sweetening agents, flavoring agents, coloring agents, and preserving agents in order to provide pharmaceutically elegant and palatable preparations.

The tablets may be uncoated or they may be coated by known techniques to delay disintegration and absorption in the gastrointestinal tract and thereby provide a sustained action over a longer period. For example, a time delay material such as glyceryl monostearate or glyceryl distearate may be employed. They may also be coated by the techniques described in U.S. Patent Nos. 4,356,108; 4,166,452; and 4,265,874, incorporated herein by reference, to form osmotic therapeutic tablets for controlled release. Formulations for oral use may also be presented as hard gelatin capsules where the active ingredient is mixed with an inert solid diluent, for example, calcium carbonate, calcium phosphate or kaolin, or a soft gelatin capsules wherein the active ingredient is mixed with water or an oil medium, for example peanut oil, liquid paraffin, or olive oil. Aqueous suspensions may contain the active compounds in admixture with excipients suitable for the manufacture of aqueous suspensions. Such excipients are suspending agents, for example sodium carboxymethylcellulose, methylcellulose, hydroxypropylmethylcellulose, sodium alginate, polyvinylpyrrolidone, gum tragacanth and gum acacia; dispersing or wetting agents may be a naturally-occurring phosphatide such as lecithin, or condensation products of an alkylene oxide with fatty acids, for example polyoxyethylene stearate, or condensation products of ethylene oxide with long chain aliphatic alcohols, for example, heptadecaethyl-eneoxycetanol, or condensation products of ethylene oxide with partial esters derived from fatty acids and a hexitol such as polyoxyethylene sorbitol monooleate, or condensation products of ethylene oxide with partial esters derived from fatty acids and hexitol anhydrides, for example polyethylene sorbitan monooleate. The aqueous suspensions may also contain one or more coloring agents, one or more flavoring agents, and one or more sweetening agents, such as sucrose or saccharin. Oily suspensions may be formulated by suspending the active ingredient in a vegetable oil, for example arachis oil, olive oil, sesame oil or coconut oil, or in a mineral oil such as a liquid paraffin.

Thus, in a further embodiment, there is provided a pharmaceutical composition comprising a compound of the present invention, or a pharmaceutically acceptable salt, solvate, or prodrug therof, and one or more pharmaceutically acceptable carriers, excipients, or diluents. The compounds of the present invention selectively act as modulators of RAGE binding to a single endogenous ligand, i.e., selective modulators of β-amyloid - RAGE interaction, and therefore are especially advantageous in freatment of Alzheimer's disease and related dementias. Further, the compounds of the present invention act as modulators of RAGE interaction with two or more endogenous ligands in preference to others. Such compounds are advantageous in treatment of related or unrelated pathologies mediated by RAGE, i.e., Alzheimer's disease and cancer. Further, the compounds of the present invention act as modulators of RAGE binding to each and every one of its ligands, thereby preventing the generation of oxidative stress and activation of NF-κB regulated genes, such as the cytokines IL-1, and TNF- α. Thus, antagonizing the binding of physiological ligands to RAGE prevent targeted pathophysiological consequences and useful for management or treatment of diseases, i.e., AGE-RAGE interaction leading to diabetic complications, S100/EN- RAGE/calgranulin-RAGE interaction leading to inflammatory diseases, β-amyloid- RAGE interaction leading to Alzheimer's Disease, and amphoterin-RAGE interaction leading to cancer. I. RAGE and the Complications of Diabetes As noted above, the compounds of the present invention are useful in the freatment of the complications of diabetes. It has been shown that nonenzymatic glycoxidation of macromolecules ultimately resulting in the formation of advanced glycation endproducts (AGEs) is enhanced at sites of inflammation, in renal failure, in the presence of hyperglycemia and other conditions associated with systemic or local oxidant stress (Dyer, D., et al, J. Clin. Invest, 91:2463-2469 (1993); Reddy, S., et al, Biochem., 34:10872-10878 (1995); Dyer, D., et α ., J. Biol. Chem., 266:11654-11660 (1991); Degenhardt, T., et al, Cell Mol Biol, 44:1139-1145 (1998)). Accumulation of AGEs in the vasculature can occur focally, as in the joint amyloid composed of AGE-β 2 - microglobulin found in patients with dialysis-related amyloidosis (Miyata, T., et al, J. Clin. Invest, 92: 1243-1252 (1993); Miyata, T., et al, J. Clin. Invest, 98: 1088-1094 (1996)), or generally, as exemplified by the vasculature and tissues of patients with diabetes (Schmidt, A-M., et al, Nature Med., 1:1002-1004 (1995)). The progressive accumulation of AGEs over time in patients with diabetes suggests that endogenous clearance mechanisms are not able to function effectively at sites of AGE deposition Such accumulated AGEs have the capacity to alter cellular properties by a number of mechanisms. Although RAGE is expressed at low levels in normal tissues and vasculature, in an environment where the receptor's ligands accumulate, it has been shown that RAGE becomes upregulated (Li, J. et al, J. Biol. Chem., 272:16498-16506 (1997); Li, J., et al, J. Biol. Chem., 273:30870-30878 (1998); Tanaka, N, et al, J. Biol. Chem,. 275:25781-25790(2000)). RAGE expression is increased in endothelium, smooth muscle cells and infiltrating mononuclear phagocytes in diabetic vasculature. Also, studies in cell culture have demonstrated that AGE-RAGE interaction caused changes in cellular properties important in vascular homeostasis. II. RAGE and Cellular Dysfunction in the Amyloidoses Also as noted above, the compounds of the present invention are useful in treating amyloidoses and Alzheimer's disease. RAGE appears to be a cell surface receptor which binds β-sheet fϊbrillar material regardless of the composition of the subunits (amyloid-β peptide, Aβ, amylin, serum amyloid A, prion-derived peptide) (Yan, S. -D.,et al., Nature, 382:685-691 (1996); Yan, S-D., et al, Nat. Med., 6:643-651 (2000)). Deposition of amyloid has been shown to result in enhanced expression of RAGE. For example, in the brains of patients with Alzheimer's disease (AD), RAGE expression increases in neurons and glia (Yan, S. -D., et al., Nature 382:685-691 (1996)). The consequences of Aβ interaction with RAGE appear to be quite different on neurons versus microglia. Whereas microglia become activated as a consequence of AJ3-RAGE interaction, as reflected by increased motility and expression of cytokines, early RAGE-mediated neuronal activation is superceded by cytotoxicity at later tunes. Further evidence of a role for RAGE in cellular interactions of Aβ concerns inhibition of Aβ-induced cerebral vasoconstriction and transfer of the peptide across the blood-brain barrier to brain parenchyma when the receptor was blocked (Kumar, S., et al.,Neurosci Program, pl41- #275.19 (2000)). Inhibition of RAGE-amyloid interaction has been shown to decrease expression of cellular RAGE and cell stress markers (as well as ΝF-kB activation), and diminish amyloid deposition (Yan, S-D., et al, Nat. Med., 6:643-651 (2000)) suggesting a role for RAGE-amyloid interaction in both perturbation of cellular properties in an environment enriched for amyloid (even at early stages) as well as in amyloid accumulation. III. RAGE and Propagation of the Immune/Inflammatory Response As noted above, the compounds of the present invention are useful in treating inflammation. For example, SlOO/calgranulins have been shown to comprise a family of closely related calcium-binding polypeptides characterized by two EF-hand regions linked by a connecting peptide (Schafer, B. et al, TIBS, 21:134-140 (1996); Zimmer, D., et al, Brain Res. Bull, 37:417-429 (1995); Rammes, A., et al, J. Biol. Chem., 272:9496- 9502 (1997); Lugering, N, et al, Eur. J. Clin. Invest, 25:659-664 (1995)). Although they lack signal peptides, it has long been known that S 100/calgranulins gain access to the extracellular space, especially at sites of chronic irnmune/inflammatory responses, as in cystic fibrosis and rheumatoid arthritis. RAGE is a receptor for many members of the SlOO/calgranulin family, mediating their proinflammatory effects on cells such as lymphocytes and mononuclear phagocytes. Also, studies on delayed-type hypersensitivity response, colitis in IL-10 null mice, collagen-induced arthritis, and experimental autoimmune encephalitis models suggest that RAGE-ligand interaction (presumably with SlOO/calgranulins) has a proximal role in the inflammatory cascade. IV. RAGE and Amphoterin As noted above, the compounds of the present invention are useful in treating tumor and tumor metastasis. For example, amphoterin is a high mobility group I nonhistone chromosomal DNA binding protein (Rauvala, H., et al, J. Biol. Chem., 262:16625-16635 (1987); Parkikinen, J., et α/., J. Biol. Chem. 268:19726-19738 (1993)) which has been shown to interact with RAGE. It has been shown that amphoterin promotes neurite outgrowth, as well as serving as a surface for assembly of protease complexes in the fibrinolytic system (also known to contribute to cell mobility). In addition, a local tumor growth inhibitory effect of blocking RAGE has been observed in a primary tumor model (C6 glioma), the Lewis lung metastasis model (Taguchi, A.,et al, Nature 405:354-360 (2000)), and spontaneously arising papillomas in mice expressing the v-Ha-ras transgene (Leder, A., et al, Proc. Natl Acad. Sci, 87:9178-9182 (1990)). Amphoterin is a high mobility group I nonhistone chromosomal DNA binding protein (Rauvala, H. and R. Pihlaskari. 1987. Isolation and some characteristics of an adhesive factor of brain that enhances neurite outgrowth in central neurons. J. Biol. Chem. 262:16625-16635. (Parkikinen, J., E. Raulo, j. Merenmies, R. Nolo, E. Kajander, M. Baumann, and H. Rauvala. 1993. Amphoterin, the 30 kDa protein in a family of HIMGl-type polypeptides. J. Biol. Chem. 268:19 726-19738). V. RAGE and Erectile Dysfunction Relaxation of the smooth muscle cells in the cavemosal arterioles and sinuses results in increased blood flow into the penis, raising corpus cavernosum pressure to culminate in penile erection. Nitric oxide is considered the principle stimulator of cavemosal smooth muscle relaxation (See Wingard CJ, Clinton W, Branam H, Stopper VS, Lewis RW, Mills TM, Chitaley K. Antagonism of Rho-kinase stimulates rat penile erection via a nitric oxide-independent pathway. Nature Medicine 2001 Jan;7(l): 119- 122). RAGE activation produces oxidants (See Yan, S-D., Schmidt A-M., Anderson, G., Zhang, j., Brett, j., Zou, Y-S., Pinsky, D., and Stem, D. Enhanced cellular oxidant stress by the interaction of advanced glycation endproducts with their receptors/binding proteins. J. Biol. Chem. 269:9889-9887, 1994.) via an NADH oxidase-like enzyme, therefore suppressing the circulation of nitric oxide. Potentially by inhibiting the activation of RAGE signaling pathways by decreasing the intracellular production of AGEs, generation of oxidants will be attenuated. RAGE blockers may promote and facilitate penile erection by blocking the access of ligands to RAGE. The calcium-sensitizing Rho-kinase pathway may play a synergistic role in cavemosal vasoconsfriction to maintain penile flaccidity. The antagonism of Rho-kinase results in increased corpus cavernosum pressure, initiating the erectile response independently of nitric oxide (Wingard et al). One of the signaling mechanisms activated by RAGE involves the Rho-kinase family such as cdc42 and rac (See Huttunen HJ, Fages C, Rauvala H. Receptor for advanced glycation end products (RAGE)- mediated neurite outgrowth and activation of NF-kappaB require the cytoplasmic domain of the receptor but different downstream signaling pathways, j Biol Chem 1999 Jul 9;274(28):19919-24). Thus, inhibiting activation of Rho-kinases via suppression of RAGE signaling pathways will enhance and stimulate penile erection independently of nitric oxide.
