| Description: | Compounds of the invention were tested for ACK1 inhibition activity. 1 uL compounds prepared at 15× in 4 mM DMSO were combined with 9 uL ATP solution in assay buffer containing 50 mM Hepes, 1% glycerol, 1.665 mM MnCl2 and Poly-(GT)-Biotin (Cisbio #61GT0BLD, 1:1500 dilution) in ProxiPlate-384 Plus plate (PerkinElmer #6008280). Final DMSO concentration was 0.25% with an ATP final concentration of 100 uM. The reaction was started by adding 5 uL ACK1 solution (Carna, 15 pg/uL final in assay) in an enzyme buffer containing 50 mM Hepes, 0.24 mM EGTA, 0.024% Brij-35, 3 mM DTT, 0.01% BSA. Reaction was allowed to occur for 20 min., shaking, at RT. Anti PT66 acceptor beads and Streptavidin donor beads (PerkinElmer #6760602R) were prepared by adding each at 1:160 dilution in a detection buffer containing 25 mM Tris-HCl, 250 mM NaCl, 100 mM EDTA, 0.25% BSA. Prepared beads were added to assay plate at 5 uL well and allowed to incubate protected from light, shaking, for 2 hrs at RT. Plates were read on AlphaQuest reader. |
