Embodiment 1
[0043] Embodiment 1: Human type 1 11β-hydroxysteroid dehydrogenase (11β-HSD 1) Inhibition; primary human distribution in culture In Vitro Tests on Humanized Adipocytes
[0044] Inhibition of human 11β-HSD 1 enzyme was evaluated on primary human adipocytes in culture (ZenBio).
[0045] plan:
[0046] Preadipocytes were thawed and their viability was confirmed. Then, put the preadipocytes in the specific preadipocyte medium (PM-1) provided by ZenBio in 96-well microplate; place the plate at 37°C and 5% CO 2 Incubation. One or more days after cell fusion, PM-1 was replaced with a more specific differentiation medium (DM), also provided by ZenBio, containing isobutylmethylxanthine, insulin, dexamethasone, and a PPAR agonist. After a minimum of 7 days, the cells will differentiate into adipocytes. Then, mature adipocytes were maintained in adipocyte maintenance medium (AM) for 4 to 6 days. Cells were then placed in steroid-deficient conditions for 48 h in the presence of ...
Embodiment 2
[0053] Example 2: Single oral administration of different type 1 11β-HS in C57BL / 6N mice D. Inhibitor compounds post blood Evaluation of pulp bioactivity (bioavailability / strength / efficacy)
[0054] plan
[0055] Evaluations were performed in non-fasted male C57BL / 6N strain mice aged 4 to 6 weeks. Compounds to be tested or vehicle (0.5% methylcellulose in water, 10 ml / kg) were administered orally; n=3 mice per treatment.
[0056] Blood samples were collected 1 h and 4 h after administration; tubes were centrifuged to obtain plasma and frozen at -70°C until bioanalysis. Plasma bioactivity (2% final volume) was analyzed at each dose tested by using inhibition of human type 1 11[beta]-HSD as the detection system for each compound (SPA technology). The percent inhibition (compared to vehicle-treated mice) was calculated for each dose.
[0057] Compounds tested:
[0058] Compound 1: (4-hydroxy-2-methyl-1,1-dioxo-2H-benzo[e][1,2]thiazin-3-yl)(naphthalene-2-yl)methanone;
...
Embodiment 3
[0070] Example 3: Single oral administration of different type 1 11β-HS in C57BL / 6N mice D. Inhibitor Compound Whitening Evaluation of bioactivity of adipose tissue (distribution / intensity / efficacy)
[0071] plan
[0072] Four hours after administration, mice were euthanized and inguinal white adipose tissue was removed and frozen at -70°C until the day of bioanalysis. White adipose tissue was homogenized in liquid nitrogen and then treated with acetonitrile (1 ml distilled water corresponds to 4 ml acetonitrile and 200 mg inguinal white adipose tissue) to extract soluble material. The acetonitrile fractions were collected, then dried, and the residue was dissolved in 1 ml DMSO (corresponding to 300 mg white adipose tissue). Inguinal white adipose tissue (equivalent to 150 μg tissue per well, 1% DMSO) was analyzed for bioactivity by using inhibition of human type 1 11β-HSD as a detection system (SPA technology) for each compound and each dose tested.
