E4602New VLS-1488(KIF18A-IN-6 ) VLS-1488 (KIF18A-IN-6) is an oral inhibitor of KIF18A with an IC50 of 0.016 μM. KIF18A is a mitotic kinesin motor protein that localizes at the plus-end of kinetochore microtubule spindle fibers and is crucial for cell division in aneuploid cancer cells with high chromosomal instability (CIN).

E4595 SB-743921 SB-743921 (SB-921) is an inhibitor of Kinesin Spindle Protein (KSP), a mitotic protein essential for cell cycle control and motility. It functions by selectively targeting rapidly dividing cells and disrupting spindle formation during cell division, leading to G2/M phase arrest and ultimately causing cell death. It also inhibits proliferation and induces apoptosis in diffuse large B-cell lymphoma (DLBCL) cell lines.
S6953 GW406108X GW406108X (GW108X) is an inhibitor of Kif15 (Kinesin-12) with an IC50 of 0.82 μM in the ATPase assay. GW406108X inhibits recombinant ULK1 kinase activity with a pIC50 of 6.37 and blocks autophagy in cells, without affecting the upstream signalling kinases mTORC1 and AMPK.
S7972 Litronesib Litronesib (LY2523355) is a selective allosteric inhibitor of the human mitosis-specific kinesin Eg5. LY2523355 also exhibits highly schedule-dependent, broad-spectrum anticancer activity against tumor models and causes mitotic arrest and apoptosis in cancer cells.
E0779 Paprotrain Paprotrain is a cell-permeable inhibitor of the kinesin MKLP-2, inhibits the ATPase activity of MKLP-2 with an IC50 of 1.35 μM and a Ki of 3.36 μM and shows a moderate inhibition activity on DYRK1A with an IC50 of 5.5 μM.
S7354 Filanesib hydrochloride Filanesib (ARRY-520) hydrochloride is a kinesin spindle protein (KSP) inhibitor that blocks the separation of centrosomes and assembly of spindles in the early stage of cell mitosis, and cell proliferation.
S5522 H-Cys(Trt)-OH H-Cys(Trt)-OH (L-Cys(Trt)-OH, H-L-Cys(Trt)-OH, S-Tritylcysteine,S-Trityl-L-cysteine) is a specific inhibitor of Eg5 that inhibits Eg5-driven microtubule sliding velocity in a reversible fashion with an IC50 of 500 nM.
S5933 K 858 K858 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.
