Pharmacological activity. The compounds of the present invention are active against the receptor product of the CB1 gene. The affinity of the compounds of the invention for central cannabinoid receptors can be demonstrated in methods described in Devane et al, Molecular Pharmacology, 1988, 34, 605 or those described in WO01 / 70700 or EP 656354. Alternatively, the test can be performed as follows. 10 μg of prepared membranes from stably transfected cells with the CB1 gene are suspended in 200 μl of 100 mM NaCl, 5 mM MgCl 2, 1 mM EDTA, 50 mM HEPES (pH 7.4), 1 mM DTT, 0.1% BSA and 100 μM of GPD. To this is added a concentration of agonist (CP55940) of CE80. The required concentration of the test compound of 0.1 μCi [35 C] -GTP? S. The reaction is allowed to advance at 30 ° C for 45 minutes. The samples are then transferred onto GF / B filters using a cell harvester and washed with buffer for washing (50 mM Tris (pH 7.4), 5 mM MgCl 2, 50 mM NaCl). The filters are then covered with scintillation fluid and counted against the amount of [35 S] -GTP? S retained by the filter. The activity is measured in the absence of all ligands (minimal activity) or in the presence of a CE8o concentration of compound CP55940 (maximum activity). These activities are set as activity of 0% and 100% respectively. At various concentrations of the new ligand, the activity is calculated as a percentage of the maximum activity and plotted. The data are adjusted using the equation y = A (BA) / 1 + ((C / x) UD)) and the Cl50 value is determined as the concentration required to provide the maximum inhibition half of GTP? S binding under the conditions used. The compounds of the present invention are active in the BC1 receptor (Clso < 1 micromolar). The most preferred compounds have IC50 < 200 nanomolar. For example, the IC50 of Example 10 is 6.0 nM and of Example 1 1 is 6.4 nM. It is believed that the compounds of the invention are selective CB 1 antagonists or inverse agonists. Potency, selectivity profile and propensity to side effect may limit the clinical utility of current known compounds that have CB1 antagonist / inverse agonist properties. In this regard, the pre-clinical evaluation of compounds of the present invention in models of gastrointestinal and / or cardiovascular function indicate that they offer significant advantages in comparison with the representative CB 1 inverse antagonist / antagonist agents. The compounds of the invention may provide additional benefits in terms of potency, selectivity profile, bioavailability, plasma half-life, hemato-encephalic permeability, plasma protein binding (eg, higher free drug fraction) or solubility in comparison with representative reference CB1 inverse antagonist / antagonist agents. The utility of the compounds of the present invention in the treatment of obesity and related conditions was demonstrated by a reduction in body weight in obese mice induced by cafeteria diet. C57B 1 / 6J female mice are supplied, ad libitum, access to a dense-calorie "cafeteria" diet (soft chocolate / cocoa-type snacks, fatty cheese and nougat) and normal laboratory food for 8-10 weeks. The compounds to be evaluated are then administered systemically (iv, ip, se or po) once per route for a minimum of 5 days, and the body weights of the mice are monitored on a daily basis. The simultaneous assessment of adiposity is carried out by means of DEXA imaging in the baseline and at the conclusion of the study. Blood sampling is also done to evaluate changes in plasma markers related to obesity.
