PTH1 receptor/Parathyroid hormone receptor in Rat (target type: SINGLE PROTEIN) [ChEMBL: CHEMBL6038] [GtoPdb: 331] [UniProtKB: P25961]
ChEMBL cAMP Assay: Instead of HKRK-B7 cells, LLC-PK46_RATO_PTH1R cells overexpressing rat PTH1R, which were established at Chugai Pharmaceutical, were used to take measurements in a similar manner to Test Example 1: HKRK-B7 or LLC-PK1 cells were seeded into a 96-well plate at 1×105 cells/well and incubated overnight. On the following day, 50 μl of cAMP assay buffer (DMEM, 2 mM IBMX, 0.2 mg/ml bovine serum albumin, 35 mM Hepes-NaOH, pH 7.4) containing human PTH(1-34) or each compound was added and the plate was placed in a 37° C. incubator. The cells were incubated for 20 minutes. After removing the medium, the cells were washed with 100 μl of cAMP assay buffer once. The plate was placed on dry ice powder to freeze the cells and then removed from the dry ice. The cells were lysed with 40 μl of 50 mM HCl and frozen again on dry ice. The amount of intracellular cAMP produced was measured using a commercially available cAMP EIA kit (Biotrack cAMP EIA system, GE health care). F 5.62 pEC50 2400 nM EC50 US-9428505-B2. Hydantoin derivative (2016)
