| | Inhibitory Effect on LRRK2 |
| Description: | After the compound was dissolved in 100% DMSO at 10 mM, it was serially diluted to the range of 1 μM to 10 μM using biochemical LRRK2 assay buffer (50 mM HEPES (4-(2-hydroxyethyl)-1-piperazineethanesulfonic acid) pH 7.5, 10 mM MgCl2, 1 mM EGTA (1,2-bis(o-aminophenoxy)ethane-N,N,N′,N′-tetraacetic acid), 2 mM DTT (dithiothreitol), and 0.01% TWEEN-20 (Aldrich)). Purified LRRK2 (CARNA BIOSCIENCES) was added to a black U-bottom 96-well microtiter plate containing 6 μl of the serially diluted compound, followed by incubation at room temperature for 30 minutes. For the kinase reaction, ATP and a substrate solution specific urea-polypeptide (ULIGHT -poly TK, PerkinElimer) were added. The reaction was carried out at room temperature for 1 hour, and it was detected with an detection solution (brand name: LANCE ) containing EDTA. A LANCE detection solution containing europium-labeled antibody (LRRK2 specific PT66) was added, followed by incubation at room temperature for 50 minutes, to terminate the kinase experiment. The phosphorylated substrate was detected by 665 nm emission measurement. |
