EP1 receptor/Prostanoid EP1 receptor in Mouse (target type: SINGLE PROTEIN) [ChEMBL: CHEMBL2181] [GtoPdb: 340] [UniProtKB: P35375]
GtoPdb Measuring antagonism of agonist-induced intracellular calcium elevation in cells expressing mouse EP1 receptor. - 8.03 pIC50 9.3 nM IC50 US9181187B2. Therapeutic agent for urinary excretion disorder (2015)
ChEMBL Inhibition Assay: The cells expressing mouse EP1 receptor were seeded at 104 cells/well in 96-well plates and cultured for 2 days with 10% Fetal Bovine Serum (FBS)/alpha Modified Eagle Medium (alphaMEM) in the incubator (37° C., 5% CO2). The cells were washed with phosphate buffer, and load buffer (10% FBS/αMEM containing Fura2/AM (5 uM), indomethacin (20 uM) and probenecid (2.5 mM)) was then added to each well and cells were left standing for 1 hour. Load buffer of each well was discarded and assay buffer (Hank's Balanced Salt Solution (HBSS) containing indomethacin (2.5 mM), probenecid (2.5 mM), HEPES-NaOH (10 mM) and 0.1% (w/v) Bovine Serum Albumin (BSA)) was added to each well and plates were left at room temperature in a dark room for 1 hour. Afterwards, compounds of the present invention (10 uL) or PGE2 (10 uL) prepared with assay buffer was added to each well and intracellular calcium concentrations were measured using a Fluorescence Drug Screening System.
