Biological Activity for Deschloroclozapine

Deschloroclozapine is a high affinity and highly potent activator of muscarinic DREADDs (Ki values are 6.3 nM for hM3Dq and 4.2 nM for hM4Di, in vitro; EC50 values are 0.13 nM for hM3Dq and 0.081 nM for hM4Di, in vitro). Derivative of clozapine (Cat. No. 0444). Exhibits 100-fold greater affinity for hM3Dq and hM4Di compared to clozapine N-oxide (CNO; Cat. No. 4936), and 50-fold greater affinity compared to DREADD agonist 21 (Cat. No. 5548). Displays low 'off-target' receptor binding (Ki >100 nM at majority of GPCRs, ion channels and transporters tested). Displays rapid (approx. 10 minutes after i.p injection) binding and activation of hM3Dq and hM4Di in mice and non-human primates. Induces spatial memory deficits in non-human primates expressing hM4Di in the prefrontal cortex.

Allosteric GPCR Pharmacology Poster

Allosteric GPCR Pharmacology Poster

G protein-coupled receptors (GPCRs) are intrinsically allosteric proteins. This poster provides insights into allosteric mechanisms of GPCR biology, highlighting key facets of GPCR allostery and therapeutic applications of allosteric modulators.

GPCR Efficacy and Biased Agonism Poster

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.
