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].
GAT564 (Compound 15d) is a highly effective allosteric modulator of cannabinoid 1 receptor (CB1R), having EC50 values of 87 nM and 320 nM for cAMP and β-arrestin2, respectively. It significantly enhances the binding of orthosteric ligands to hCB1R. Moreover, GAT564 exhibits remarkable efficacy as a topical agent, resulting in a significant reduction of intraocular pressure (IOP) in an ocular normotensive murine model of glaucoma [1].
