CP 945598 hydrochloride is a selective and high affinity CB1 antagonist with Ki value of 0.7 and 0.12 nM for binding and functional assays, respectively [1].
The CB1 receptor is a G protein-coupled cannabinoid receptor located primarily in the central and peripheral nervous system and plays an important role in energy homeostasis.
CP 945598 dose-dependently reversed the four characteristic effects (hypothermia, anti-nociception, hypo-locomotion, and catalepsy) of a centrally acting cannabinoid agonist (CP 55940).
In mice model, CP 945598 (17.8 mg/kg s.c.) increased locomotor activity. In Sprague–
Dawley rats, CP 945598 reduced food intake in a dose and concentration dependent way. With doses of 10 mg/kg and 30 mg/kg, CP 945598 increased energy expenditure by 16% and 19%, respectively. Also, ex vivo brain receptor occupancy increased to 33–36% in a dose-related way. In diet-induced obese mice, CP 945598 significantly decreased body weight by 9% compared to vehicle-treated mice [2].

Kinase experiment: | Membranes are prepared from CHOK1 cells stably transfected with the human CB-1 receptor cDNA. GTPγ [35S] binding assays are performed in a 96-well FlashPlate format in duplicate using 100 pM GTPγ [35S] and 10μg membrane per well in assay buffer composed of 50 mM Tris HCl, pH 7.4, 3 mM MgCl2, pH 7.4, 10 mM MgCl2, 20 mM EGTA, 100 mM NaCl, 30 µM GDP, 0.1% bovine serum albumin, and the following protease inhibitors: 100 μg/mL bacitracin, 100 μg/mL benzamidine, 5 μg/mL aprotinin, 5 μg/mL leupeptin. The assay mix is then incubated with increasing concentrations of antagonist (10-10M to 10-5 M) for 10 min and challenged with the cannabinoid agonist CP-55,940 (10 μM). Assays are performed at 30°C for 1 h. The FlashPlates are then centrifuged at 2000 g for 10 min. Stimulation of GTPγ [35S] binding is then quantified using a Wallac Microbeta. EC50 calculations are done using Prism by GraphPad. Inverse agonism is measured in the absence of agonist. |
Animal experiment: | Male, 14 week old C57/Bl6/6J mice which has been maintained on a high fat diet (45% kcal from fat) for 6 weeks are selected for the DIO weight loss study. The animals body weights range at least five standard deviations from age-matched chow-fed control animals mean body weight. Mice are singly housed. The mean starting weight of all animals is 38.9±0.5 g. On day 0, mice are randomLy assigned to treatment groups (n=10 per group). Mice are dosed daily with vehicle or 10 mg/kg (p.o.) CP-945,598 over 10 days, starting approximately at 30 min before the start of the 12 h dark cycle. BW and food intake are recorded daily. Analysis of variance and comparison of means are calculated for daily and cumulative FI and cumulative BW measurements. P < 0.05 is considered statistically significant. |
