CB1R Allosteric modulator 2 (compound 18) is a potent allosteric modulator of the CB1R receptor. It exhibits negative modulation of the functional activity of orthosteric ligands (NAM) at CB1Rs, as demonstrated in previous studies [1].
CB1R Allosteric modulator 4 is an effective and positive modulator of cannabinoid type-1 (CB1R), exhibiting significant biological activity. This compound inhibits the production of cAMP and demonstrates strong β-arrestin-2 recruitment [1].
