Ispinesib (SB-715992)Ispinesib (SB-715992) is a potent, specific and reversible inhibitor of kinesin spindle protein (KSP) with Ki app of 1.7 nM in a cell-free assay, no inhibition to CENP-E, RabK6, MCAK, MKLP1, KHC or Kif1A. Ispinesib induces mitotic arrest and apoptotic cell death. Phase 2. |
Representative photographs of fluorescent staining of microtubules and nuclei in MDA-MB-231 cells 24 h post-treatment with 4 nM of ispinesib or vinblastine or their combination. Arrows and arrowheads denote mitotic cells with monoploar and bipolar spindles, respectively. Scale bars, 20 um.

SB743921 HClSB743921 is a kinesin spindle protein (KSP) inhibitor with Ki of 0.1 nM, almost no affinity to MKLP1, Kin2, Kif1A, Kif15, KHC, Kif4 and CENP-E. Phase 1/2. |
HeLa cells expressing iRFP were seeded onto 96-well plates and incubated with buffer or different concentrations of SB743921.During the next five days, the plate was scanned with an infrared imaging system (upper panel) to quantify the infrared signals (lower panel). |

AZ 3146AZ3146 is a selective Mps1 inhibitor with IC50 of ~35 nM, contributes to recruitment of CENP-E (kinesin-related motor protein), less potent to FAK, JNK1, JNK2, and Kit. |
Dose response curves for the treatment of breast cancer cell lines in the absence or presence of escalating doses of the TTK inhibitor (TTKi) AZ3146. The survival of cells was measured using the CellTitre MTS/MTA assay carried out 6 days after treatment. Percentage survival (n ¼ 3 per dose) was calculated as the percentage of the signal from treated cells to that from control cells. |
|
| S7090 |
GSK923295GSK923295 is a first-in-class, specific allosteric inhibitor of CENP-E kinesin motor ATPase with Ki of 3.2 nM, and less potent to mutant I182 and T183. Phase 1. |
(f) HeLa cells were treated with mitotic kinesin CENP-E inhibitor GSK923295 (50 nM) for 1 h to generate misaligned kinetochores. After fixation, cells were stained for ACA, tubulin, and TIP60. Statistical significance was tested by two-sided t-test and represented by asterisks corresponding to ***, p < 0.001. Scale bars, 5 μm. |

| S7488 |
MPI-0479605MPI-0479605 is an ATP competitive and selective inhibitor of mitotic kinase Mps1 with IC50 of 1.8 nM, >40-fold selectivity over other kinases. |
||
| S5933 |
K 858K858 is a novel and potent inhibitor of Eg5 with an IC50 of 1.3 μM for inhibiting the ATPase activity of Eg5, showing at least 150-fold more selective for Eg5 than other members of the kinesin superfamily. |
