| | Radioligand Binding Assay (Ki) and Norepinephrine Uptake Assay (IC50) |
| Description: | Compounds were evaluated the inhibition of [3H] nisoxetine binding to MDCK-Net6 cells, stably transfected with the human norepinephrine transporter (hNET). Data from wells containing 1 uM desipramine were used to define non-specific hNET binding. Total radioligand bound is defined by addition of binding buffer alone in the presence of [3H]nisoxetine (Perkin-Elmer). The radioligand binding reaction was initiated by addition of [3H]nisoxetine, and incubated for 2 h at 37 deg C. The KD value estimated for [3H]nisoxetine was 10 nM using intact whole cells. The inhibition constant (Ki) was calculated by the Cheng and Prusoff equation. IC50 Values were obtained from inhibition of norepinephrine uptake in MDCK-Net6 cells, stably transfected with the human NET. |
