gpr68

Ogremorphin (GPR68-IN-1) is a potent inhibitor of GPR68 with an EC50 of 170 nM, used in the study of autoimmune chronic inflammatory diseases [1].

Ogerin is a selective GPR68 positive allosteric modulator (pEC50: 6.83) that blocks recall in fear conditioning in mice. It exhibits inverse agonist and antagonist activity (Ki, 220 nM) at the A2A receptor and weak antagonist activity (Ki, 736 nM) at the 5-HT2B receptor.

MS48107 is a potent, selective positive allosteric modulator of G protein-coupled receptor 68 (GPR68), demonstrating specificity for GPR68 over closely related proton GPCRs, neurotransmitter transporters, and hERG ion channels. It effectively crosses the blood-brain barrier (BBB) in mice.
