UMK57
Based on 1 Customer Validation
UMK57 is a MCAK activator and kinetochore-microtubule destabilizer. UMK57 enhances MCAK-dependent microtubule depolymerization, increases kinetochore-microtubule turnover, reduces chromosome mis-segregation and lagging chromosomes, and inhibits cancer cell proliferation. UMK57 triggers adaptive resistance in Aurora B cancer cells via reversible Aurora B signaling pathway alterations. UMK57 can be used for the research of solid tumors.

Biological Activity

Kif2c/MCAK |
UMK57 (100 nM; 1-72 h) reduces anaphase lagging chromosome rates in SW620 cells acutely[1].
UMK57 (100 nM; 1-72 h) selectively increases the levels of Aurora kinase A and TPX2 on mitotic spindles without altering Aurora kinase A activation status in SW620 cells[1].
UMK57 specifically potentiates MCAK-mediated microtubule depolymerization in vitro without inhibiting kinesin ATPase activity[2].
UMK57 (0.1-50 μM; 3 days) inhibits U2OS cell proliferation in a dose-dependent manner[2].
UMK57 (100 nM; <1h) suppresses chromosome mis-segregation in U2OS, HeLa, and SW-620 CIN cancer cells[2].
UMK57 (100 nM; 1 h) reduces metaphase k-MT attachment stability in U2OS cells in an MCAK-dependent manner, with no effect on prometaphase k-MT stability initially, but induces reversible hyper-stabilization of prometaphase k-MTs after extended continuous treatment[2].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
