| in vitro transactivation assay |
Description: | The in vitro transactivation assay determined the capacity of the compounds of the invention to activate the Nurr1:RXR heterodimers. Naive SHSY-5Y cells were transiently co-transfected, using Lipofectamine 2000 (Invitrogen), with a plasmid expressing the human receptor Nurr1, a plasmid expressing the RXR human receptor (RXRα or RXRγ receptor) and a reporter plasmid DR5-TK-Luc. After 24 hours, the culture medium was changed. The test compounds were added (final concentration between 0.5, 2.5 and 12.5 μM) in the culture medium. After incubation overnight, the expression of luciferase was measured (FIG. 1A). Positive control cells were treated with XCT0135908 (1 μM; WO 2005/047268) which induces activation of the Nurr1:RXR heterodimer and results in maximal expression of luciferase. |
