RTICBM-303
RTICBM-303 is a blood-brain barrier-penetrant cannabinoid receptor type 1 (CB1) inhibitor. RTICBM-303 concentration-dependently decreases the Emax of the agonist CP55,940, increases the binding of [3H]CP55,940, and inhibits CB1 receptor signaling. RTICBM-303 selectively reduces cue-induced and drug-priming-induced drug-seeking relapse behaviors in rats. RTICBM-303 can be used in studies related to addictive behaviors.

In Vitro
RTICBM-303 (compound 11) potently inhibits CP55,940-stimulated calcium mobilization in CHO-RD-HGA16 cells expressing human CB1, with a pIC50 of 7.07. It acts as an insurmountable antagonist and exhibits no agonist activity[1].
RTICBM-303 (60 min) inhibits CP55,940-induced G protein activation in human CB1-expressing HEK293 cell membranes and mouse cerebellar membranes, with pIC50 values of 5.91 and 6.24, respectively[1].
RTICBM-303 positively regulates the binding of [3H]CP55,940 to cell membranes of HEK293 cells expressing human CB1, increasing the binding rate to 218% of the baseline level, with a pEC50 of 6.33[1].
RTICBM-303 exhibits low apparent permeability in MDCK-MDR1 cells, with Papp values of < 0.1 × 10-6 cm/s in both transport directions[1].

i.p.; single dose; 10 minutes prior (food-maintained operant responding tests) -
Result:Significantly reduced lever-pressing responses in both cue-induced and drug-primed psychostimulant reinstatement tests at 10 mg/kg.
Failed to alter food-reinforced operant response rates at 5.6 mg/kg or 10 mg/kg.
