DREADD agonist 21
Potent muscarinic DREADD agonist (pEC50 values are 8.91, 8.48 and 7.77 for hM1Dq, hM3Dq and hM4Di in vitro, respectively). Exhibits > 10-fold higher affinity for hM1Dq and hM4Di compared to wild type receptors. Also displays little to no activity at wild type M3 receptors. Activates neurons expressing hM3Dq DREADDS and inhibits activity in neurons expressing hM4Di in vivo. Displays excellent brain permeability. Water soluble salt also available, DREADD agonist 21 hydrochloride (Cat. No. 6422).

Chemogenetics Research Bulletin
Produced by Tocris, the chemogenetics research bulletin provides an introduction to chemogenetic methods to manipulate neuronal activity. It outlines the development of RASSLs, DREADDs and PSAMs, and the use of chemogenetic compounds. DREADD ligands and PSEMs available from Tocris are highlighted.
GPCR Efficacy and Biased Agonism Poster
GPCRs can interact with multiple distinct transducers or regulatory proteins and these can be preferentially engaged in an agonist-specific manner giving rise to biased agonism. This poster discusses cutting edge GPCR signaling pharmacology and highlights therapeutic applications of biased agonism.
