TAK-960

TAK-960 is a n orally available PLK1 inhibitor with potential antineoplastic activity. Polo-like kinase 1 inhibitor TAK-960 selectively inhibits PLK1, inducing selective G2/M cell-cycle arrest followed by apoptosis in a variety of tumor cells while causing reversible cell-cycle arrest at the G1 and G2 stages without apoptosis in normal cells. PLK1 inhibition may result in the inhibition of proliferation in PLK1-overexpressed tumor cells. PLK1, named after the polo gene of Drosophila melanogaster, is a serine/threonine kinase crucial in the regulation of mitosis.

How to use

In Vitro:

TAK-960 treatment causes accumulation of G2-M cells, aberrant polo mitosis morphology, and increased phosphorylation of histone H3 (pHH3). TAK-960 (2-1000 nM; 72 hours) inhibits proliferation of multiple cancer cell lines, with mean EC50 values ranging from 8.4 to 46.9 nM, but not in nondividing normal cells. TAK-960 (8 nM) leads to G2/M cell cycle arrest without significant cytotoxicity in HeLa cells.

In Vivo:

TAK-960 exhibits (10 mg/kg; p.o.; once daily for 2 weeks) significant efficacy against multiple tumor xenografts. In animal models, TAK-960 (p.o.) increases pHH3 in a dose-dependent manner and significantly inhibits the growth of HT-29 colorectal cancer xenografts.
