KSP-IA

A potent, specific, allosteric and cell-active inhibitor of KSP with IC50 of 11 nM; has no ihibitory activity toward other kinesins, includin CENP-E, MKLP-1, KIF-3A, and uKHC (IC50>50 uM); induces the formation of monoastral spindles, causes mitotic arrest in a dose-dependent manner (EC50=30 nM) in A2780 ovarian carcinoma cells; sustained KSP inhibition activates the proapoptotic protein, Bax, and both activation of the spindle checkpoint and subsequent mitotic slippage are required for Bax activation.
