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]

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
