| Description |
A cell-permeable Erk Inhibitor II (Cat. No. 328007 ) structural analog that acts as a isoform-selective Aurora B kinase inhibitor (95% inhibition at 1 µM; [ATP] = 10 µM) with little or no activity against Aurora A or C (0% and 16% inhibition, respectively, at 1 µM; [ATP] = 15 µM), Also shown to inhibit Chk2, IRR/INSRR, and Ack1/TNK2 (% inhibition/[ATP] = 81%/70 µM, 75%/200 µM, and 71%/70 µM, respectively), while exhibiting much reduced or no inhibitory potency toward a panel of 228 other kinases, including Erk1/2.
