Description:

HETEROARYL-IMIDAZOLE DERIVATIVES AS CANNABINOID CB 1

RECEPTOR ANTAGONISTS

FIELD OF THE INVENTION

The present invention relates to a novel heteroaryl-imidazole compound which is effective as a cannabinoid CB 1 receptor inverse agonist or antagonist.

DESCRIPTION OF THE PRIOR ART

The World Health Organization (WHO) recently reported that obesity has become a global epidemic, posing a serious threat to public health because of the increased risk of associated health problems (See Report of a WHO Consultation on Obesity: Obesity-Preventing and Managing a Global Epidemic; World Health Organization: Geneva, 1997). Obesity is characterized by excess body fat, especially visceral fat, and constitutes a pro-inflammatory state eventually leading to serious health consequences. There are growing evidences that obesity as a chronic disease cannot be cured by short-term dieting or exercise alone, but additional pharmacological treatments would lead to higher success rates. CB 1 cannabinoid receptor belongs to G-protein-coupled receptor (GPCR) type and is coupled to inhibitory G proteins (G(i/o)) to inhibit certain adenylyl cyclase isozymes, leading to decreased cAMP production, decreased Ca 2+ conductance, increased K + conductance, and increased mitogen-activated protein kinase activity (See Di Marzo et al., Nat. Rev. Drug Discovery 2004, 3, 771-784; Rhee, M. H. et al., J Neurochem. 1998, 71, 1525-1534). The major physiological effect of cannabinoids (in the central nervous system (CNS) and neuronal tissues) is the modulation of neurotransmitter release via activation of presynaptic CB 1 receptors located on distinct types of axon terminals throughout the brain (See Howlett, A. C. et al., Neuropharmacology 2004, 47 (Suppl. 1), 345-358). The CB 1 receptor is mainly expressed in several brain areas including the limbic system (amygdala, hippocampus), hypothalamus, cerebral cortex, cerebellum, and basal ganglia, hi the cerebellum and basal ganglia, cannabinoids modulate the locomotor activity. In the limbic system, cannabinoids influence learning, memory, emotion, and motivation, and through activation of CB 1 receptors in the limbic system-hypothalamus axis, cannabinoids have an important role in the control of appetite. Moreover, lower levels of CB 1 receptors can also be found in peripheral tissues including urinary bladder, testis, prostate, GI tract, heart, lung, adrenal gland,

parotid gland, bone marrow, uterus, ovary, and adipose tissue (See Cota, D. et al., J. Clin. Invest 2003, 112, 423-431; Ravinet Trillou, C. et al., Int. J. Obes. Relat. Metab. Disord. 2004, 28, 640-648; Galiegue, S. et al., Eur. J. Biochem. 1995, 232, 54-61; Howlett, A. C. et al., Pharmacol. Rev. 2002, 54, 161-202). Many preclinical in vitro and in vivo experiments have been shown that CB 1 receptor antagonists can influence energy homeostasis by central and peripheral mechanisms and may represent promising targets to treat diseases that are characterized by impaired energy balance. Already the first published studies with rimonabant (SR141716) in both rodents (See Arnone, M. et al., Psychopharmacology (Berlin) 1997, 132, 104-106) and primates (See Simiand, J.; Keane, M.; Keane, P. E.; Soubrie, P. Behav. Pharmacol. 1998, 9, 179-181) showed clear differentiation, i.e., marked effects on sweet food intake versus marginal effects on regular chow intake or water drinking. Many other preclinical "proof of concept" studies have been performed in the meantime with several CB agonists and antagonists to further uncover the amount and mode of contribution of cannabinergic system modulators to energy homeostasis. Almost all of those studies have been recently reviewed (See Smith, R. A. et al., IDrugs 2005, 8, 53-66).

Considering the important impact of obesity on public health and the lack of any efficient and viable drug to cure it, it is no surprise that CB 1 antagonists are currently the subject of intense studies, which were published in several reviews (See Adam, J. et al., Expert Opin.Ther. Patents, 2002, 12(10), 1475-1489; Hertzog, D. L. Expert Opin.Ther. Patents, 2004, 14(10), 1435-1452; Lange, J. H. M. et al., Drug Discov. Today, 2005, 10, 693-702; Bishop, M. J. J Med. Chem., 2006, 49(14), 4008- 4016).

SUMMARY OF THE INVENTION

Pharmacological Test: In vitro Activity Analysis

The compounds of the present invention were analyzed for their binding characteristics for CB 1 and CB 2 and the pharmacological activity thereof in accordance with the method disclosed in [Devane WA, Dysarz FA 3 rd , Johnson MR, Melvin LS and Howlett AC, Determination and characterization of a cannabinoid receptor in rat brain, MoL Pharmacol., 34(5): 605-13(1998)]. The analysis was performed using [ 3 H]CP-55940 which is a selectively radioactivity-labeled 5-(l,l-dimethyheptyl)-2[5- hydroxy-2-(3-hydroxypropyl)-cyclohexyl]-phenol, purchased from PerkinElmer Life Sciences, Inc. (Boston, Massachusetts, U.S.A.), through a rat CB-I receptor binding protocol as follows.

The tissue obtained from the brain of SD rats was homogenized with a Dounce homogenate system in TME(50 mM Tris, 3 mM MgCl 2 and 1 mM EDTA, pH 7.4) at 4 ° C, and the homogenate was centrifuged at 48,000g for 30 min. at 4 ° C . The pellet was resuspended in 5 mi of TME and the suspension was divided into aliquots and stored at -70 ° C until its use in the following assay.

2 μJt of the test compound was diluted in dimethylsulphoxide and was added to a deep well of a polypropylene plate, to which 50 μi of [ 3 H]CP-55940 diluted in a ligand buffer solution (0.1 % bovine serum albumin(BAS)+TME) was added. The tissue concentrations were determined by Bradford protein analysis, and 148 μJL of brain tissue of the required concentration was added to the plate. The plate was covered and placed in a 30 ° C incubator for 60 min, and then transformed on GF/B

filtermat pretreated in polyethylenimine (PEI) using a cell harvester. Each filter was washed five times and dried at 60 ° C for 1 hr. Then, the degree of radioactivity retained by the filter was measured using Wallac Microbeta™ (PerkinElmer Life Sciences, Inc., Massachusetts, U.S.A.) and the activity of the compound for inhibiting CB 1 receptor was determined there from and compared with that of the control, rimonabant which is known as a cannabinoid CB 1 receptor antagonist. The results are shown in Table 1.

Table 1

As shown in Table 1, the inventive compounds are effective as a cannabinoid CB 1 receptor ligand.

While the invention has been described with respect to the specific embodiments, it should be recognized that various modifications and changes may be made by those skilled in the art to the invention which also fall within the scope of the invention as defined as the appended claims.
