ChEMBL Radioligand Binding Assay: Radioligand binding assays were carried out in a volume of 200 mL (96-well plates) which contained 100 mL of cell memebranes, [3H]flumazenil at a concentration of 1 nM for α1, α2, α3 subunits and 0.5 nM for α5 subunits and the test compound in the range of 10-10−3x10−6 M. Nonspecific binding was defined by 10−5 M diazepam and typically represented less than 5% of the total binding. Assays were incubated to equilibrium for 1 hour at 4 C. and harvested onto GF/C uni-filters (Packard) by filtration using a Packard harvester and washing with ice-cold wash buffer (50 mM Tris; pH 7.5). After drying, filter-retained radioactivity was detected by liquid scintillation counting. B 8.33 pKi 4.7 nM Ki US-8846719-B2. Isoxazolo-pyridine derivatives (2014)
ChEMBL Binding affinity to GABA-A alpha5 (unknown origin) B 8.33 pKi 4.7 nM Ki J Med Chem (2020) 63: 3425-3446 [PMID:31738537]
GtoPdb Binding affinity determined in a radioligand displacement assay: test compound competition for [3H]flumazenil at α5β3γ2 GABAA channels transiently expressed in HEK293 cells. - 8.33 pKi 4.7 nM Ki WO2009071476A1. Isoxazolo-pyridine derivatives (2009)
