In Vitro Caliper Kinase Assay: For comparison between certain PKC inhibitors of the present application and structurally comparable PIM kinase inhibitors, the activity of PIM2 was measured using an in vitro Caliper kinase assay. Liquid handling and incubation steps were done on an Innovadyne Nanodrop Express equipped with a robotic arm (Thermo CatX, Caliper Twister II) and an incubator (Liconic STX40, Thermo Cytomat 2C450). The 384 well microtiter assay plates were prepared by addition of 50 nl per well of compound solution in 90% DMSO. The kinase reactions were started by stepwise addition of 4.5 ul per well of peptide/ATP-solution (50 mM HEPES, pH 7.5, 1 mM DTT, 0.02% Tween20, 0.02% BSA, 0.6% DMSO, 10 mM beta-glycerophosphate, and 10 uM sodium orthovanadate, 1 mM MgCl2, 25 uM ATP, and 2 uM S6 peptide) and 4.5 ul per well of enzyme solution (50 mM HEPES, pH 7.5, 1 mM DTT, 0.02% Tween20, 0.02% BSA, 0.6% DMSO, 10 mM beta-glycerophosphate, and 10 uM sodium orthovanadate, 1 mM MgCl2, and 0.6 nM PIM2 enzyme).
