The metabolic syndrome is the result of an increased peripheral resistance to insulin, and is characterized by hyperinsulinaemia, glycose intolerance, an alteration in lipid metabolism, and arterial hypertension (Grundy, S. M. : Hypertriglyceridemia, insulin resistance, and the metabolic syndrome. Am. J. Cardiol. 1999, 83, 25F-29F). Obesity is often associated with these metabolic disorders, and the coming together of these multiple risk factors promotes the development of the atheromatous pathology that causes arterial thrombosis, which is today the primary cause of mortality in industrialized regions. Peroxisome proliferator activated receptors (PPARs) belong to the superfamily of transcription factor nuclear receptors. After activation, they form a heterodimer with the 9-cis-retinoic acid receptor (RXR); this complex (PPAR-RXR) binds specifically to DNA sequences located in regions that regulate genes involved in lipid and carbohydrate metabolism (Pineda Torra, I., Gervois, P. and Staels, B.: Peroxisome proliferator-activated receptor alpha in metabolic disease, inflammation, atherosclerosis and aging. Curr. Opin. Lipidol. 1999, 10, 151-159, Vamecq. J. and Latruffe, N.: Medical significance of peroxisome proliferator-activated receptors. Lancet 1999, 354, 141-148). The activation of PPARs, firstly, restores certain altered metabolic pathways which predispose to atherosclerosis and, secondly, reduces the inflammatory events which promote the development and fissuration of the atheroma plaque.

The compounds of the present invention are characterized by means of their original structure, their affinity with respect to PPAR-alpha and/or PPAR-gamma receptors and their pharmacological profile.

A solution of 0.71 g (2.16 mmol) of intermediate 6h in 10 ml of DMF is then run in dropwise and stirring is continued at 80°C for 2 h 30 min. After concentration to dryness, the residue obtained is taken up with H20 and extracted with ethyl acetate. After drying over MgS04, the organic phases are evaporated and the light-coloured oil obtained is placed in 17 mi of ethanol in the presence of 0.04 g of para-toluenesulphonic acid. This mixture is refluxed for 2 h and then concentrated to dryness. The residue is taken up with H20 and then extracted with ethyl acetate. After drying and evaporation of the organic phases, the light-coloured oil obtained is purified by flash chromatography on silica (petroleum ether-EtOAc: 90-10) and 0.87g of crystals is isolated (yield = 90%). They are then placed in 15 mi of DMF at 0°C under nitrogen and 0.09g (2.34 mmol) of NaH (60% in paraffin) is added.

The reaction medium is stirred at ambient temperature for 30 min and 1,1, 1- trifluoro-4-iodobutane (0.56g, 2.34 mmol) diluted in 10 mi of DMF is then run in and stirring is continued for 15 h at ambient temperature and then for 13 h

PHARMACOLOGICAL EVALUATION In vitro Activation of transcription (transactivation) of the reporter gene controlled by specific response elements after binding of the ligand to the receptor (reporter gene assay).

These experiments were carried out according to J. M. Lehmann et aL (J. Biol. Chem 1995,270 : 12953-12956) with a few modifications.

Subconfluent Cos-7 cells (ATCC, CRL-1651) are transfected with, firstly, (i) the chimeric receptors containing the human PPARa-, PPARy-or PPAR6-ligand-binding domain fused to the yeast galactosidase DNA-binding domain (Gal-4) and, secondly, (ii) the reporter plasmid containing five copies of the Gal-4 response element upstream of the thymidine kinase promoter adjacent to the luciferase gene (p5xUAS-tk-Luc). After 24 hours, these cells are treated for the following 24 hours with the compounds or their carrier, and the luciferase activity is evaluated after cell extraction according to the supplier's recommendations (Promega).

The results have been reported in Table 5 below, in which the term"hit"denotes a compound for which the level of transactivation is significant without however allowing an EC50 value to be defined.
