Definitions

  • the present invention relates to novel compounds which are 2- (benzoylamino)benzoic acids and which modulate the activity of peroxisome proliferator- activated receptors (PPAR) ⁇ and/or ⁇ .
  • PPAR peroxisome proliferator- activated receptors
  • the said compounds are predicted to be useful in the treatment of metabolic diseases, e.g. type II diabetes.
  • PPARs peroxisome proliferator-activated receptors
  • PPARs were first cloned as the nuclear receptors that mediate the effects of synthetic compounds called peroxisome proliferators on gene transcription. It soon became clear that eicosanoids and fatty acids can also regulate gene transcription through PPARs.
  • PPARs act in a similar manner to other nuclear hormone receptors. First, they bind a specific element in the promoter region of target genes. PPAR and some other nuclear hormone receptors bind the promoter only as a heterodimer with the receptor for 9- cis retinoic acid, RXR (retinoid X receptor). Second, they activate transcription in response to binding ofthe hormone (ligand).
  • PPAR:RXR heterodimer binding ofthe ligand of either receptor can activate the complex, but binding of both ligands simultaneously is more potent.
  • Three PPAR isotypes have been identified: ⁇ , ⁇ (also called ⁇ and NUC1) and ⁇ .
  • PPAR ⁇ (GenBank Accession No. NM_005036) is expressed most in brown adipose tissue and liver, then kidney, heart and skeletal muscle.
  • PPAR ⁇ GenBank Accession No. NM_005037
  • PPAR ⁇ is mainly expressed in adipose tissue, and to a lesser extent in colon, the immune system and the retina.
  • PPAR ⁇ is found in many tissues but the highest expression is in the gut, kidney and heart.
  • PPARs are ligand-dependent transcription factors: activation of target gene transcription depends on the binding ofthe ligand to the receptor. Some ligands are shared by the three isotypes, such as polyunsaturated fatty acids and probably oxidized fatty acids.
  • Type I insulin-dependent diabetes mellitus
  • IDDM insulin-dependent diabetes mellitus
  • Type II non-insulin-dependent diabetes mellitus
  • NIDDM non-insulin-dependent diabetes mellitus
  • NTDDM is linked to heredity and obesity.
  • NIDDM is almost invariably accompanied by dyslipidemia, characterized by elevated triglycerides (TGs), VLDL-C and increased small dense LDL-C in combination with decreased levels of HDL-C and prolonged postprandial hyperlipidemia.
  • This form of dyslipidemia is highly atherogenic and thus represents a major risk factor for the development of premature atherosclerosis and coronary artery disease (CAD), which is the major cause of mortality in diabetic patients.
  • CAD coronary artery disease
  • a direct correlation between low HDL levels and incidence of CAD has been identified.
  • this pathological lipid profile or "lipotoxicity" is suggested to contribute to ⁇ - cell failure and as a consequence impaired glucose stimulated insulin release.
  • PPAR ⁇ and PPAR ⁇ are key sensors and transcriptional modulators of lipid and glucose homeostasis, respectively. Accordingly, a selective "dual action drug" that selectively binds and activates PPAR ⁇ and ⁇ is hypothesized to mechanistically target the two major metabolic abnormalities observed in type II diabetic patients and thus therapeutically intervene with insulin resistance, CAD and possibly also impaired insulin secretion or ⁇ -cell failure.
  • Murakami et al. discloses a thiazolidinedione derivative which activated both PPAR ⁇ and PPAR ⁇ , and restored reduced lipid oxidation, when administered to obese rats. It was suggested that PPAR ⁇ agonism has a protective effect against abnormal lipid metabolism in liver of obese rats. Agents modulating both PPAR ⁇ and PPAR ⁇ are also disclosed in Shibata, T. et al. (1999) Eur. J. Pharmacol. 364: 211-219; and in WO 99/19313.

  • Crude extracts were prepared from E. coli (BL21(DE3)pLysS, Novagen) producing GST-PPAR ⁇ LBD or GST-PPAR ⁇ LBD fusion proteins by freeze thawing in buffer containing 50 mM Tris-HCl pH 7.9, 250 mM KC1, 10% glycerol, 1% Triton X-100, 10 mM DTT, lmM PMSF, 10 ⁇ g/mL DNase and 10 mM MgCl.
  • Competitive ligand binding assays were performed on immobilized GST-PPAR ⁇ LBD or GST-PPAR ⁇ LBD fusion proteins from crude extracts incubated with glutathione-Sepharose 4B (Amersham Pharmacia Biotech).
  • the slu ⁇ y was washed three times in binding buffer containing 50 mM Tris-HCL, pH7.9, 50 mM KC1, 0.1% Triton-XlOO, 10 mM DTT, 2 mM EDTA, dispensed in 96-well filter plates (MHVB N45, Millipore) and incubated with a fixed amount tritiated ligand and different concentrations of cold competing ligands. Equilibrium binding was reached after incubation for 2 hours at room temperature on a plate shaker.

  • the animal model used was ob/ob mouse and as a reference compound the known PPAR ⁇ ligand, rosiglitazone.
  • the animals were orally treated during 7 days and parameters as food intake, body weight, plasma glucose, insulin, cholesterol, triglycerides and free fatty acids were monitored.
  • Compounds of formula I were shown to give dose related pharmacological effects.
  • PPAR ⁇ ligand binding domain (LBD) has previously been described in literature (Nolte, R. T. et al. (1998) Nature 395: 137-143; Uppenberg, J. et al. (1998) J. Biol. Chem. 273: 31108-31112).
  • the present inventors have determined the structure of human PPAR ⁇ LBD in complex with one ofthe compounds (Example 1) according to the invention. As indicated in Fig. 1, the compound according to Example 1 was shown to be located in the ligand binding pocket of human PPAR ⁇ .
  • the compound was found in an elongated conformation and occupied a region in proximity with, and approximately parallel to, helix 3 (the numbering of helices and strands follow the convention of Uppenberg et al. supra) and in proximity to beta-strand 3 and helices 5 and 2b.
  • the interactions between the compound (ligand) according to the invention and human PPAR ⁇ can be separated into four categories: (1) Interaction between the dibromo-phenyl moiety ofthe ligand and the predominantly hydrophobic pocket of human PPAR ⁇ , in particular the side chains of Ile326, Met329, Leu330, Leu333, Ala292 and Arg288.
  • the compounds according to the invention bind in a novel binding mode. These compounds modulate the activity of PPARs in a range of agonistic effects determined in a cell based reporter assay.
