AZ 3146 Chemical Structure

CAS No. 1124329-14-1

AZ3146 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.

  • Following single thymidine arrest (STA) for 24 h (the numbers above the arrows indicate the time in hours), cells were released into nocodazole (Noc) for 12 h and then treated with DMSO or Noc plus MG132 (to prevent mitotic exit). After 2 h, cells were processed for immunoprecipitation (IP). cells were synchronized using AZ3146 or other small molecule inhibitors. Cell lysates were then analyzed for BUBR1. Noc, nocodazole.

AZ3146 also inhibits FAK, JNK1, JNK2 and Kit. AZ3146 significantly inhibits phosphorylation of Mps1 in cells. Mitotic-specific phospho forms of aurora B and BubR1 are not affected by AZ3146. AZ3146 does not inhibit Cdk1 or aurora B in mitotic cells. HeLa cells treated with nocodazole and 2 μM AZ3146 only delay mitosis briefly and then rereplicate their genomes, indicating that AZ3146 overrides the SAC. AZ3146 also inhibits an already established SAC signal, as after release from a nocodazole block, AZ3146 dramatically accelerates mitotic exit.During an otherwise unperturbed mitosis, AZ3146 reduces the time to complete mitosis from 90 minutes in controls to 32 minutes. Strikingly, ~90% of AZ3146-treated HeLa cells undergo abnormal mitoses, although ~50% enter anaphase without aligning all of their chromosomes, and ~30% exit mitosis without undergoing obvious chromosome segregation. AZ3146 has a dramatic effect on kinetochore localization of Mad2, reducing its levels to ~15%, but its effect on Mad1 is less pronounced, with levels remaining at ~60%. When Mps1 is inhibited by AZ3146 before mitotic entry, subsequent recruitment of Mad1 and Mad2 to kinetochores is abolished. However, if Mps1 is inhibited by AZ3146 after mitotic entry, the Mad1–C-Mad2 core complex remains kinetochore bound, but O-Mad2 is not recruited to the core. [1]

Definitions of molecular mass, molecular weight, molar mass and molar weight:

Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
