RTICBM-189 is a potent, brain-penetrant allosteric modulator of the cannabinoid type-1 (CB1) receptor with a pIC50 of 7.54 in Ca2+ mobilization assay. RTICBM-189 has pIC50s of 5.29 and 6.25 for hCB1 and mCB1, respectively. RTICBM-189 significantly and selectively attenuates the reinstatement of the cocaine-seeking behavior in rats[1]. RTICBM-189 (10 mg/kg; i.p.) significantly and selectively attenuates reinstatement of the cocaine-seeking behavior in rats[1].RTICBM-189 (10 mg/kg; i.p.) rapidly absorbs into systemic circulation, with peak plasma concentration (Cmax,plasma=288.4 ng/mL) observed at tmax,plasma of 0.4 h post-dose. Peak brain levels are also reached at tmax,brain of 0.4 h with a significantly higher Cmax,brain value of 594.6 ng/mL in the brain[1].
