Catalog Number: 4936
Chemical Name: 8-Chloro-11-(4-methyl-4-oxido-1-piperazinyl)-5H-dibenzo[b,e][1,4]diazepine
Biological Activity
Metabolite of clozapine (Cat. No. 0444). Activates human muscarinic designer receptors (DREADDs) in vitro. Silences hippocampal neurons expressing hM4 DREADDs in vitro.
