5、AEB071) inhibits PKC, with Ki values in the subnanomolar to lownanomolar range. When Sotrastaurin is tested on a selected panel of kinases, the only enzyme on whichSotrastaurin displays an IC50value below 1 M is glycogen synthase kinase 3 1. Sotrastaurin (AEB071)inhibits p-MARCKS, a PKC substrate, a

6、nd pS6 in all the cell lines, independently of the mutational status.There is a slight inhibition of pERK at lower doses also in the GNA11 mutant cells, but not in the WT cells atany concentrations. This is consistent with previous reports indicating that Sotrastaurin inhibits ERK1/2phosphorylation

Sotrastaurin (STN) treatmentof liver donors and orthotopic liver transplantation (OLT) recipients (Gr.I) or of OLT recipients alone (Gr.II)prolongs animal survival, as 9 out of 10 rats in Gr. I, and 6 out of 6 rats in Gr.II survive 14 days. In contrast,only 4 out of 10 control OLT r

The reaction is stopped by adding 50 L of amixture containing 100 mM EDTA, 200 M ATP, 0.1% Triton X-100, and 0.375 g/well streptavidin-coatedscintillation proximity assay beads in PBS without Ca2+ and Mg2+. Incorporated radioactivity is measured ina MicroBetaTrilux counter for 1 mi
