| | Activity on Human GSK-3beta |
| Description: | The activity on human GSK-3β of the compounds of the invention listed in the following Table 1 and of the comparison compound C was assessed at five concentrations ranging from 10 μM to 1 nM with ten-fold dilutions in duplicate using the following methods (according to Meijer et al., Chem. Biol., 2003-10:1255-1266).Human recombinant enzyme GSK-3β was incubated for 90 minutes at 22° C. in the presence of compounds or vehicle in a reaction buffer containing ATP plus 100 nM unphosphorylated specific substrate peptide (Ulight-CFFKNIVTPRTPPPSQGK-amide). Substrate phosphorylation was measured by LANCE technology (PerkinElmer, CT, USA).The IC50 values (concentration causing a half maximal inhibition of control specific activity) were determined by non-linear regression analysis of the inhibition curves generated with mean replicate values using Hill equation curve fitting. |
