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].
