What is 11-Piperazinyldibenzo[b,e][1,4]diazepine?

Description

DREADD agonist 21 activates hM3Dq (EC₅₀ = 1.7 nM), a designer receptor exclusively activated by designer drugs (DREADD) derived from the human muscarinic acetylcholine M₃ receptor. It does not agonize the hM3 receptor and displays relatively weaker binding affinities for serotonin 5-HT_2A, 5-HT_2C, α_1A-adrenergic, and histamine H₁ receptors (K_is = 66, 170, 280, and 6 nM, respectively).

The Uses of 11-Piperazinyldibenzo[b,e][1,4]diazepine

DREADD agonist 21 is an agonist of hM3Dq, a designer receptor exclusively activated by designer drugs (DREADD). It preferentially binds hM3Dq?DREADDs over endogenous hM3?receptors.
