Potency data for probe BI-113823 and control BI-5832


In vitro potency


Target name Target information Species Assay description Compound conc. BI-113823 BI-5832 Publication of assay conditions
BDKRB1 Membranes of CHO-K1 cells expressing human recombinant B1R Homo sapiens Radioligand binding assay (displacement of kallidin, hBDKRB1 ) : Non-specific binding is estimated in the presence of 10 µM Des-Arg9- (Leu8)-Bradykinin. Membranes are filtered and washed, the filters are then counted to determine [3H]Kallidin[des-Arg10, Leu9] specifically bound. 10 µM Ki = 5.3 nM Ki = 431 nM DOI: 10.1111/j.1533-2500.2011.00528.x
BDKRB1 Rattus norvegicus Radioligand binding assay (displacement of kallidin, rat BDKRB1 ) : Non-specific binding is estimated in the presence of 10 µM Des-Arg9- (Leu8)-Bradykinin. Membranes are filtered and washed, the filters are then counted to determine [3H]Kallidin[des-Arg10, Leu9] specifically bound. 10 µM Ki = 13.3 nM DOI: 10.1111/j.1533-2500.2011.00528.x
BDKRB1 Oryctolagus cuniculus Radioligand binding assay (displacement of kallidin, rabbit BDKRB1 ) : Non-specific binding is estimated in the presence of 10 µM Des-Arg9- (Leu8)-Bradykinin. Membranes are filtered and washed, the filters are then counted to determine [3H]Kallidin[des-Arg10, Leu9] specifically bound. 10 µM Ki = 15.3 nM DOI: 10.1111/j.1533-2500.2011.00528.x
BDKRB2 Homo sapiens Radioligand binding assay (displacement of kallidin, human BDKRB2 ) : Non-specific binding is estimated in the presence of 10 µM Des-Arg9- (Leu8)-Bradykinin. Membranes are filtered and washed, the filters are then counted to determine [3H]Kallidin[des-Arg10, Leu9] specifically bound. 10 µM Ki > 10 µM DOI: 10.1111/j.1533-2500.2011.00528.x
