S6796 BTB-1 BTB-1 is a novel, selective and reversible inhibitor of the mitotic motor protein Kif18A with IC50 of 1.69 μM.
Nat Commun, 2024, 15(1):5448
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.

E5883New AM-9022 AM-9022 is an orally active, potent, and selective inhibitor of KIF18A, a mitotic kinesin motor protein critical for chromosome alignment and segregation. It exhibits significant anti-cancer effects in human breast and ovarian tumor models.
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.
E5992New VLS-1272 VLS-1272 is an orally bioavailable, potent, ATP non-competitive, microtubule-dependent, and highly selective inhibitor of KIF18A with an IC50 of 41 nM. It induces mitotic defects with strong anti-mitotic, anti-cancer, and anti-proliferative effects, leading to dose-dependent tumor growth inhibition and can be used for the study of cancers with high chromosomal instability.
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.
E1180 Sovilnesib (AMG 650) AMG 650 (Sovilnesib) is an oral, first in class, selective kinesin-like protein KIF18A inhibitor, can be used for the research of cancer.
