TAK-960

Polo-like kinases (Plks) are serine/threonine kinases with key roles in cell cycling. TAK-960 is an orally bioavailable, selective inhibitor of Plks with IC50 values of 0.8, 16.9, and 50.2 nM for Plk1, Plk2, and Plk3, respectively. It exhibits greater than 20-fold selectivity for Plk1 over FAK, MLCK, and the tyrosine protein kinase Fes, and has minimal activity against a panel of 282 other kinases. It inhibits the proliferation of various cancer cell lines, including MDR1-expressing tumors, and also prevents tumor growth in several human cancer cell xenograft models, including a disseminated model of AML- and MDR1-expressing hematological tumors.Formal Name: 4-[(9-cyclopentyl-7,7-difluoro-6,7,8,9-tetrahydro-5-methyl-6-oxo-5H-pyrimido[4,5-b][1,4]diazepin-2-yl)amino]-2-fluoro-5-methoxy-N-(1-methyl-4-piperidinyl)-benzamide.
