JHU 37160

High affinity and highly potent activator of hM3Dq and hM4Di DREADDs (Ki values are 1.9 nM and 3.6 nM for hM3Dq and hM4Di in vitro, respectively; EC50 values are 18.5 nM and 0.2 nM for hM3Dq and hM4Di in vitro, respectively). Displays approximately 25-fold higher affinity for hM4Di compared to DREADD agonist 21 . Selectively displaces [3H]clozapine from DREADDs in vivo, but not from other clozapine binding sites. Inhibits locomotor activity in mice expressing hM3Dq and hM4Di in D1-expressing neurons, and increases hM3Dq-stimulated locomotion in rats expressing hM3Dq in TH-expressing neurons. Brain penetrant in mice, rats and non-human primates.
