Biological Activity

TAK-960 is an orally bioavailable, potent, and selective polo-like kinase 1 (PLK1) inhibitor. By inhibiting PLK1, TAK-960 disrupts mitotic progression, causing cell cycle arrest at the G2/M phase, accumulation of aberrant polo mitosis morphology, and elevated phosphorylation of histone H3. These downstream mitotic defects lead to the inhibition of cancer cell proliferation and potent antitumor activity in multiple tumor xenograft models, including multidrug-resistant malignancies. [1]

FAQ
Q: Why does a DMSO stock precipitate in media/saline?
A: It is caused by unheated aqueous media (supersaturation), local solvent shock, or incorrect mixing sequence.
How to fix it?
  • Preheat media/saline to 37°C.
  • Mix rapidly (pipette/vortex) upon addition.
  • For complex mixes, always add the aqueous phase last.
  • Re-dissolve minor precipitates with a 37°C water bath and sonication (≤30 min).
