| | In Vitro V1b Receptor Assay |
| Description: | To determine selectivity, compounds were tested in luciferase-based transcriptional reporter gene assays expressing the human V1b receptor (hV1bR). Agonist activity of compounds on the hV1bR was determined in a transcriptional reporter gene assay in a Flp-In 293 cell line (HEK-flpin) stably transfected to express the hV1bR. These cells are transiently transfected with an NFAT responsive elements-luciferase (NFAT-Luc) reporter. Cells were exposed to serial dilutions of compounds diluted 10-fold per dose for 5 hours, followed by lysis of cells, determination of luciferase activity, and determination of compound efficacies and EC50 values through non-linear regression. AVP was used as an internal control in each experiment. |
