BACKGROUND ART Peroxisome proliferator activated receptors (PPARs) belong to the superfamily of transcription factors known as nuclear receptors. This family includes steroid, retinoid and thyroid hormone receptors. Three sub-types of PPARs have been identified in humans, rodents and'Xenopus. They are PPARa, PPARß/6 and PPARy, each encoded by a different gene and showing different tissue distribution.

The gene encoding for PPARy is transcribed in humans in three different mRNA isoforms (PPARyl, PPARy2 and PPARy3) through different splicing and promoter usage (Fajas et al., J. Biol.

Chem. 1997, 272, 18779-18789). The PPARy1 isoform shows a wide tissular distribution, while PPARy2 and PPARy3 are confined to certain tissues: PPARγ2 is expressed only in adipose tissue and PPARy3 in adipose tissue as well as in macrophages (Fajas et al., FEBS Lett. 1998, 438,55-60).

X9 Differences detected in tissue distribution as well as in the activation profile of the PPARr isoforms suggest they are involved in a variety of physiological functions playing a central role in homeostasis and lipid metabolism (Vamecg et al., Lancet 1999,354, 141-148). These functions include, for example, lipidic transport in plasma and catabolism of fatty acids, regulation of insulin sensitivity and blood glucose levels, differentiation of macrophages that form atherosclerotic plaques, inflammatory response, carcinogenesis, hyperplasia, and adipocyte differentiation, the latter being the most verified function of the PPARy (Grimaldi, Prog. Lipid Res. 2001,40, 269-281, Schiller et <BR> <BR> <BR> <BR> al. , J. Biol. Chem. 2001, 276, 14133-14137). Thus, the discovery of these transcription factors has provided new pharmacological targets for the development of useful therapeutic agents for the prevention and treatment of metabolic diseases such as diabetes, obesity and dyslipidaemia.

Non-insulin dependent diabetes mellitus (NIDDM) or type 2 diabetes is characterized by an insulin resistance in peripheral tissues, including muscle, liver, and adipose tissue. Glitazones, selective PPARy agonist compounds, are drugs that reduce insulin resistance and lower blood glucose levels. Currently two products belonging to this family, rosiglitazone and pioglitazone, have been approved for the treatment of type 2 diabetes in humans.

A great effort has been made in recent years to design new drugs that improve the side effect profile of the first glitazones, show a greater affinity as a PPARy ligands, and increase their potency in type 2 diabetes. This rational design has yielded structurally diverse compounds that show great potency and selectivity. Among them is interesting to highlight the 2-alkoxyphenylpropionic type derivatives ragaglitazar (1, EP 1049684) and tesaglitazar (2, EP 1084103). These compounds are currently in phase III and II of clinical development, respectively.

(1) (2) The use of compounds totally or partially blocking PPARy activity is useful for the inhibition of adipocyte differentiation, which constitutes an effective treatment for obesity.

PPAR8 activation has been shown to lead to increased levels of HDL cholesterol in db/db mice (Leibowitz et al, FEBS Lett. 2000, 473, 333-336), and in diabetic-obese rhesus monkeys, while lowering the levels of LDL, triglycerides, and insulin (Oliver et al, Proc Nat Acad Sci USA, 2001, 98, 5306-5311). The involvement of PPAR# in fatty acid oxidation in muscles was further sustained in PPARa knock-out mice (Muoio et al., J. Biol. Chem. 2002, 277,26089-26097). A number of PEAR. compounds have been reported to be useful in the treatment of hyperglycemia, hyperlipidemia and hypercholesterolemia (e. g. WO 02/59098, WO 01/603, WO 01/25181, WO 02/14291, WO 01/79197, WO 99/4815, WO 97/28149, WO 98/27974, WO 97/28115, WO 97/27857, WO 97/28137, WO 97/27847). Taken together, these observations suggest that PPAR6 activation is useful in the treatment and prevention of cardiovascular diseases and conditions including atherosclerosis, hypertriglyceremia and mixed dyslipidemia (WO 01/00603) In vitro studies investigating the pharmacological modulation of PPARB suggest that this kind of ligands may prove to be efficacious drugs for decreasing cardiovascular disease associated with metabolic syndrome, a condition comprised of a cluster of risk factors that also includes insulin resistance, obesity and hypertension (Mukjerheer, Drug News Perspect. 2002,15, 261-267).

Pro-differentiation and lipid accumulation effects have been reported in rodent and cultured human keratinocytes, as well as protection against cell death upon PPARB activation (Tan et al., Genes Dev. 2001,15, 3263-3277; Schmuth et al., J.

Invest. Dermatol. 2004,122, 971-983). Modulators of these activities could be useful for treating a variety of skin disorders.

In addition, PPARS has been implicated as a direct target in colorectal carcinogenesis in mice. All the evidences suggest that PPAR8 expression may promote tumour growth and, thus, may be also a potential target for the treatment of colorectal cancer (e. g. Park et al., Proc Nat Acad Sci USA, 2001, 98, 2598-2603). While PPARy is acknowledged as a master regulator of adipogenesis, PPAR8 may also play a role in adipocyte differentiation, as demonstrated by in vitro and in PPARB-deficient animals, promoting PPARy gene expression, which upon specific ligand activation promotes adipogenesis.

Thus a non-selective PPARy/6 antagonist would be also a potential drug for obesity (Shearer et al., Curr. Med. Chem.

2003,10, 267-280).

This indicate that research for compounds displaying various degrees of PPARy and PPAR5 modulation should lead to the discovery of drugs that have great potential in the treatment of diseases such as type-2 diabetes, dyslipidemia, syndrome X, cardiovascular diseases (including atherosclerosis), hypercholesteremia, colon cancer, skin disorders (including psoriasis, and wound healing, Tan et al., Expert Opín. Ther. Targets, 2004,8, 39), and bone diseases (Pei et al., J. Clin. Invest., 2004, 113, 805-806).

Consequently, it is of great interest to provide new therapeutic agents that selectively modulate PPARy, and PPARy /PPAR8.

Kundu and collaborators have described benzamides (3), (4) and (5) as N-0-glucosidase inhibitors (Comb. Chem. High.

2002,5, 545-550). These compounds are structurally close to those of this invention, but were described for different uses.

Preferred methods include, but are not limited to, the general processes shown in the attached schemes.

Proteins 2001, 32, 107-162). Final compounds (Ia) are obtained by Williamson etherification by displacement of a leaving group (LG) bonded to a type-Z radical with the phenol (IV) (using for example NaH, K2C03 or Cs2CO3 as a base in a solvent such as DMF or acetone; (Bal-Tembe et al., Bioorg. Med. Chem. 1997,5, 1381-1388 ; Cantello et al., J. Med. Chem. 1994,37, 3977-3985, Solar et al., J. Org. Chem. 1966,31, 1996-1997; EP. 875510), or by Mitsunobu reaction between (IV) and a Z-OH type alcohol in the presence of, for example, diethyl azodicarboxylate (DEAD) and triphenylphosphine in tetrahydrofurane as a solvent (Mitsunobu, Synthesis 1981, 1 ; Hughes, Org. React. 1992, 42, 335).

After basic hydrolysis of the resulting ester, the final compounds (I) are synthesized by reaction with the amine derivative (III). Alternatively, and only in the specific case of para substitution of the aromatic ring, the phenolic ether (VI) may be formed by aromatic nucleophilic substitution starting from the fluorinated compound (VII).

When-Z is a radical of the-(CH2) S-X-P-I-J-T type where X is O or S, for the alkylation of the phenol another alternative procedure may be followed (Method C).

The hydrolysis of'the esters (Xa) and (XIa) and their subsequent reaction with the amine derivative (III) also leads to the compounds (Iaa) and (Iab). The derivatives of the sulphoxide (Iac) and sulphone (Iad) types are obtained by oxidation of the corresponding thioether (Iab) in the presence of oxidizing agents such as, for example, hydrogen peroxide or m-chloroperbenzoic acid.

In the case of phenol (IV), the reaction with a doubly functionalised alkyliden derivative and, then, the nucleophilic substitution with the desired amines; or the etherification with the protected amine compound (XII) (as a trifluoroacetamide derivative, for example), and subsequent functionalisation of the amine released after its deprotection (in a basic medium, or with NaBH4 (Harland and Hodge Synthesis 1984,941-943)) yields the desired compounds.

The tertiary amines of the (Iaeb) and (Iaec) types are obtained by the treatement of the compound (Iaea) with alkylating agents or by reductive alkylation, respectively.

The amides (Iaed) are synthesized by acylation of the compound (Iaea) with the corresponding acid derivative in the presence of a tertiary amine, or by treating the secondary amine with an acid in the presence of a coupling agent such as, for example the combination of EDC and HOBT (Elmore, Amino Acids Pep. Proteins 2001, 32, 107-162). In the case of the phenol (V), the amines (Iae) are obtained by reaction of their precursor acids (XVIb), (XVIIb) and (XVIIIb) with the amine derivatives (III) following the methods outlined above.

These acids, in turn, are obtained from the phenol (V) following an analogous process to that used in the case of the phenol (IV).

The Z-OH or Z-LG type compounds are products that have already been described. Some of them are commercially available or may be prepared following methods analogous to those used to synthesize others that are already known, such as those that are explained in detail in the following documents: EP 03062228; WO 97/31907; WO 01/00603; Daoud et al. , J. Indian Chem. Soc. 1989, 66, 316-318 and Aquino, J. Med. Chem. 1996, 39, 562-569, some of them summarised in Scheme 1.

An approach for the preparation of the a-amino acids (W is - NH-CH (E) -) is the Sorensen synthesis (Mori, Tetrahedron 1985,2369-2377 ; Scheme 2), wherein dialkyl acyl-amide-malonate is alkylated in a basic medium and, after subsequent hydrolysis and decarboxylation, the desired a-amino acids (IIIa) are obtained.

MS: 621 Assay of binding to the PPARy2 The cDNA encoding for the open reading frame of the hPPARy2 is amplified by PCR (polymerase chain reaction) and inserted in the plasmid pGEX-4T-2. This construction (pGEX-hPPARγ) is introduced into E. coli where it is overexpressed and semipurified as a fusion protein with glutathione S-transferase (GST) (Elbrecht et al., J. Biol. Chem. 1999, 274, 7913-7922).

The binding of the compounds to the GST-hPPARy2 s is determined by modifications in the method described by Lehmann et al. (J. Biol. Chem. 1995,270, 12953-12957). The receptors (2.5 Ag) were incubated in 96-well plates in the presence or in the absence of the products with [3H] BRL-49853 (100 nM) for 3 h at 4°C, in a final volume of 200 HL of buffer Tris-HCl 10 mM pH: 8.0, containing KC1 50 mM and DTT 10 mM. Non-specific binding was determined in the presence of BRL-49853 100 MM. The reaction mixture was transferred to a Multiscreen Durapore (Millipore) microplate containing glutathione-Sepharose 4B in every well. The reaction mixture was left to incubate with the resin during 10 min, and then centrifuged at 735 g during 2 min. To dissociate the receptor bound to the resin, reduced glutathione 10 mM is added and incubated during 10 min. The receptor was eluted by centrifugation. Then, 800 AL of scintillation liquid were added to the elution and the contained radioactivity was quantified by liquid scintillation spectroscopy (Microbeta Wallac, Perkin Elmer).

LBD-hPPARs transactivation assay COS-7 cells were cultivated in 24-well plates and transfected with the pFACMV plasmids that encode the chimeric proteins containing the GAL4 DNA binding domain fused to the PPARy LBD. The reporter plasmid for the foregoing constructions was pFR-Luc, which contains five repetitions of the GAL4-response element in front of a promoter that controls the transcription of the luciferase gene. Lipofectamine was used as a transfection agent.

The plasmids of the chimeric receptors and the reporter gene were inserted in the cells by transitory transfection in COS-7 cells in culture. When the products were added to the culture for 48 h, the luciferase activity showed the effect of the PPAR activity modulation on the transcription of the reporter construction (Wright et al., J. Biol. Chem. 2000, 275,1873).

Cloning of human PPARa, PPARb and PPARy2 The human PPARs cDNAs were amplified through RT-PCR. For hPPARa, RNA was obtained from HepG2 cells treated with linoleic acid; for h PPARb, RNA was obtained from untreated HepG2 cells; for hPPARy2, RNA was obtained from human white adipose tissue. Each amplified fragment was cloned into pBluescript (Stratagene@) and sequenced. One clone for each construction was selected and used as template for further subcloning and PCR amplifications.

GST-fused protein construction To generate these chimeric proteins, the complete cDNA of the four human PPARs were cloned into pGEX4T2 (Amersham Biosciences). The fragment was obtained from the pBluescript-cDNAs clones digested with endonucleases. To assess the plasmid identity and to ensure the in-phase cloning of the proteins, pGEXs constructions were sequenced.

GST-hPPARy2, GST-hPPARa or GST-h PPAR5 fusion proteins were generated in Escherichia coli (BL21 strain DE3). Cells were cultured in LB medium to a density of A600= 1.6 odu, and induced for by addition of isopropyl-l-thio-p-D-galactopyranoside (IPTG) -induced cultures to a final concentration of 0.5 mM. The IPTG-induced cultures were grown at room temperature o/n, before cells were harvested by centrifugation at 5000 g for 15 min. After sonication, the GST-fusion proteins were purified from the cell pellet using glutathione-Sepharose beads, following the procedure recommended by the manufacturer (Amersham Pharmacia Biotech). Excess of gluthatione was removed o/n by dyalisis at 4°C. Receptor purity was visualized by SDS-PAGE and protein content was determined by Bradford method. Receptor aliquots were stored at-80°C until use.

GST-hPPARa and GST-hPPARo binding Using 96-well culture plates, PPARa or PPARS (5 yg) were diluted to a total volume of 100 AL with buffer consisting of 50 mM HEPES (pH: 7.0), 50 mM KCl, 5 mM EDTA andlO mM DTT, in the presence of [3H] -GW2433 (100 and 50 nM for PPARa and PPARb, respectively). Nonspecific binding was estimated in parallel incubations containing 50 AM of GW-2433. Plates were incubated for 2 h at room temperature. Free radioligand was separated from receptor-bound ligand by size exclusion chromatography using. Sephadex G-25 in 96-wells spin plates, using the Multiscreen Column Loader (Millipore). Eluted radioactivity was quantitated by liquid scintillation counting in a Microbeta counter (Perkin Elmer).
