| EP4 receptor/Prostaglandin E2 receptor EP4 subtype in Human (target type: SINGLE PROTEIN) [ChEMBL: CHEMBL1836] [GtoPdb: 343] [UniProtKB: P35408] | ||||||||
| ChEMBL | Antagonist activity at human EP4R assessed as inhibition of agonist-induced cAMP production by fluorescent cAMP tracer cAMP-d2 based FRET assay | F | 7.82 | pIC50 | 15.3 | nM | IC50 | J Med Chem (2019) 62: 2541-2563 [PMID:30707023] |
| ChEMBL | Test for Antagonism: 4 μl of a cAMP-d2/cell suspension (625000 cells/ml) were added to a test plate containing the substance solutions already initially introduced (0.05 μl; 100% DMSO, concentration range from 0.8 nM-16.5 μM). After a 20-minute preincubation at room temperature (RT), 2 μl of a 3xPGD2 solution (6 nM, in PBS-IBMX) were added and incubated in the presence of the agonist for a further 30 min at RT (volume: ¿6 μl). Subsequently, the reaction was stopped by addition of 2 μl of lysis buffer and incubated for a further 20 min at RT before the actual measurement (volume: ¿8 μl). | B | 7.82 | pIC50 | 15.3 | nM | IC50 | US-9708311-B2.
