Biological Activity

Description

JHU37160 is a Designer Receptors Exclusively Activated by Designer Drug (DREADD) agonist with Ki of 1.9 nM and 3.6 nM for human muscarinic acetylcholine M3 receptors (hM3Dq) and hM4Di in vitro, respectively. And EC50 values are 18.5 nM and 0.2 nM for hM3Dq and hM4Di in fluorescent and BRET-based assays in HEK-293 cells, respectively.

Targets

hM4Di ^[1] (Cell-free assay)	hM3Dq ^[1] (Cell-free assay)	hM4Di ^[1] (Cell-free assay)	hM3Dq ^[1] (Cell-free assay)
0.2 nM(EC50)	1.9 nM(Ki)	3.6 nM(Ki)	18.5 nM(EC50)

In vitro

JHU37160 is a potent DREADD agonist with high potency and efficacy in fluorescent and BRET-based assays in HEK-293 cells, whereas no responses are observed in untransfected HEK-293 cells.^[1]

In vivo

JHU37160 exhibits high in vivo DREADD potency. JHU37160 exhibits selective [3H]clozapine displacement from DREADDs in brain tissue from WT and D1-DREADD mice.^[1]

Protocol (from reference)

Cell Assay:^{^[1]}	Cell lines HEK-293 cells Concentrations -- Incubation Time 250 s Method HEK-293 cells are transfected with 7 µg/dish of the cDNA encoding for hM3Dq or hM4Di and 7 µg/dish of GCaMP6. 48 hours after transfection, cells are harvested, washed, resuspended in Mg2+-free Locke's buffer pH 7.4 containing 5.6 mM of glucose and approximately 200,000 cells/well are distributed in black 96-well plates. Increasing concentrations of JHU37160 are added to the cells and fluorescence intensity (excitation at 480 nM, emission at 530 nM) is measured at 18-s intervals during 250 s using a PHERAstar FSX. The net change in intracellular Ca2+ concentration is expressed as F − F0 where F is the fluorescence at a given concentration of ligand and F0 is the average of the baseline values (fluorescence values of buffer-treated wells).
