CB1 antagonist 2
Based on 1 publication(s) in Google Scholar
CB1 antagonist 2 (AM4113) is an orally active cannabinoid receptor type 1 (CB1R) antagonist. CB1 antagonist 2 suppresses appetite, reduces body weight, and blocks addictive behaviors such as heroin addiction, without causing adverse effects like nausea and depression that are associated with traditional CB1 inverse agonists. CB1 antagonist 2 can be used in studies related to obesity and opioid addiction.

Biologische Aktivität
CB1 antagonist 2 does not alter Forskolin (HY-15371)-stimulated cAMP formation in in vitro, indicating a lack of inverse agonist profile at CB1 receptors[2].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
CB1 antagonist 2 (0.3-3 mg/kg; i.p.; single administration) dose-dependently antagonizes WIN55,212-2-induced inhibition of spontaneous activity and rearing behavior, prolongation of latency, and circling behavior[1].
CB1 antagonist 2 (3-10 mg/kg; i.p.; single administration) dose-dependently inhibits heroin self-administration behavior in male Long-Evans rats. At i.p. doses of 3 mg/kg and 10 mg/kg, both the number of heroin infusions and active lever presses decrease with statistical significance[2].
CB1 antagonist 2 (2-10 mg/kg; i.p.; 14 days) causes a transient, dose-dependent reduction in food intake in rats, which in turn results in sustained, dose-dependent inhibition of body weight gain[3].
CB1 antagonist 2 (50 mg/kg; p.o.; 7 days) causes a sustained reduction in food intake in rats over 7 days, thereby significantly inhibiting body weight gain[3].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

-
Result:Completely reversed WIN55,212-2-induced suppression of ambulation to control levels at all three doses.
Partially reversed WIN55,212-2-induced suppression of rearing at all three doses, with levels significantly below controls but significantly higher than WIN55,212-2 alone.
Blocked WIN55,212-2-induced increases in latency to leave the center circle at all three doses.
Dose-dependently reduced WIN55,212-2-induced circling at all three doses.
Significantly increased scratching frequency at 1 mg/kg and 3 mg/kg compared to WIN55,212-2 alone.
Significantly increased grooming frequency and grooming duration at 3 mg/kg compared to WIN55,212-2 alone and controls.
Showed no significant effects on defecation, urination, or vocalization at any dose.

Animal Model:C57BL/6N (female, 10-16 weeks old, 20-30 g start weight; CB1 receptor knockout, wild-type)[3]
-
Dosage:10 mg/kg
-
Administration:i.p.; single dose
-
Result:Significantly reduced food intake at 2, 3, and 18 h post-administration in wild-type mice.
Produced no significant change in food intake compared to vehicle in CB1 receptor knockout mice.
-
Animal Model:Sprague-Dawley (male, 180-280 g start weight)[3]
-
Dosage:2 mg/kg; 10 mg/kg
-
Administration:i.p.; daily; 14 days
-
Result:Significantly reduced food intake on treatment days 1 and 2 at 2 mg/kg, with body weight stabilizing at 5% less than vehicle-treated rats; body weight gain was significantly reduced on treatment days 5-14.
Significantly reduced food intake on treatment days 2-4 at 10 mg/kg, with body weight stabilizing at 10% less than vehicle-treated rats; body weight gain was significantly reduced on treatment days 5-14.
Reduced fat mass by 29.3±11.4% and lean body mass by 9.0±2.2% compared to vehicle-treated rats at 10 mg/kg, though differences did not reach statistical significance.
Showed no significant differences in plasma or hypothalamic 2-AG levels, or serum glucose, triglycerides, total cholesterol, or HDL cholesterol levels between AM4113-treated and vehicle-treated rats.

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 2.08 mg/mL (5.46 mM); Clear solution
