JHU 37160

Biological Activity

JHU 37160 is a high affinity and highly potent activator of hM₃D_q and hM₄D_i DREADDs (K_i values are 1.9 nM and 3.6 nM for hM₃D_q and hM₄D_i in vitro, respectively; EC₅₀ values are 0.2 nM and 18.5 nM for hM₄D_i and hM₃D_q in vitro, respectively). Displays approximately 25-fold higher affinity for hM₄D_i compared to DREADD agonist 21 (Cat. No. 5548). Selectively displaces [³H]clozapine from DREADDs in vivo, but not from other clozapine binding sites. Inhibits locomotor activity in mice expressing hM₃D_q and hM₄D_i in D₁-expressing neurons, and increases hM₃D_q-stimulated locomotion in rats expressing hM₃D_q in TH-expressing neurons. Brain penetrant in mice, rats and non-human primates.
